         ENFORCEABILITY OF CIVIL LIABILITIES UNDER UNITED STATES LAWS
 
  Apex Silver Mines Limited is a Cayman Islands corporation, and certain of
its officers and directors are residents of various jurisdictions outside the
U.S. All or a substantial portion of the assets of the Company and of such
officers and directors, at any one time, are or may be located in
jurisdictions outside the U.S. In particular, Apex Silver Mines LDC, the
Company's majority-owned subsidiary, through which the Company conducts all of
its operations, is a Cayman Islands exempted limited duration company.
Therefore, it ordinarily could be difficult for investors to effect within the
U.S. service of process on the Company or any of those officers and directors
who reside outside the U.S. or to recover against the Company or such
individuals on judgments of courts in the U.S., including judgments predicated
upon civil liability under the U.S. federal securities laws and similar state
laws. Notwithstanding the foregoing, the Company has irrevocably agreed that
it may be served with process with respect to actions based on offers of
Shares made hereby in the U.S. by serving Apex Silver Mines Corporation, 1700
Lincoln Street, Suite 3050, Denver, Colorado 80203, its United States agent
appointed for that purpose.
 
  The Company has been advised by its Cayman Islands counsel, W. S. Walker &
Company, that there may be circumstances where the courts of the Cayman
Islands would not enforce (i) judgments of U.S. courts obtained in actions
against the Company or officers or directors of the Company not resident
within the U.S. predicated upon the civil liability provisions of the U.S.
federal securities laws and similar state laws or (ii) original actions
brought in the Cayman Islands against the Company or such persons predicated
solely upon U.S. federal securities laws. There is no treaty in effect between
the U.S. and the Cayman Islands providing for such enforcement, and there are
grounds upon which Cayman Islands courts may not enforce judgments of U.S.
courts. Certain remedies available under the laws of U.S. jurisdictions,
including certain remedies under U.S. federal securities laws, may not be
allowed in Cayman Islands courts as contrary to public policy.

  Except as expressly provided in the Underwriting Agreement, no Shares may be

                                  THE COMPANY
   
  Apex Silver Mines Limited is engaged in the exploration and development of
silver properties in South America, Central America and Central Asia. The
Company has accumulated one of the largest, privately controlled portfolios of
silver exploration properties in the world. Since 1993, the Company has
acquired the rights to or gained control of 27 non-producing silver properties
located in or near the traditional silver producing regions of Bolivia, Peru,
Chile, Honduras, Mexico, Kyrghyzstan, Mongolia and Tajikistan. Exploration
efforts since 1993 have successfully produced the Company's first development
project, the San Cristobal project (the "San Cristobal Project") located in
southern Bolivia, where regular and close spaced drilling and analysis have
delineated substantial proven and probable reserves of silver, zinc and lead.
In addition, exploration activities at the Company's other properties in
Bolivia, Peru and Honduras indicate the presence of significant quantities of
mineralized material containing silver and other metals.     
                               
                            SAN CRISTOBAL STUDY     
 
  A first phase feasibility study (the "San Cristobal Study") was completed in
August of 1997 with respect to the San Cristobal Project, which is located in
the San Cristobal district of the Potosi department in southern Bolivia, a
region that has historically produced a significant portion of the world's
silver supply. The San Cristobal Study indicates that the San Cristobal Project
contains in excess of 219 million ounces of silver in the proven and probable
reserves of 122.9 million tonnes of ore based on an average grade of
approximately 1.8 ounces of silver per tonne and contains in excess of 1.8
million tons of zinc and 0.6 million tonnes of lead in these proven and
probable reserves, based on average grades of 1.49 and 0.51 percent,
respectively. At and near the San Cristobal Project, several deposits contain
an additional 57.1 million tonnes of mineralized material, comprised of 43.3
million tonnes of mineralized material with average grades of 1.28 ounces of
silver per tonne and 1.1 percent of zinc and 0.34 percent of lead and 13.8
million tonnes of mineralized material at an average grade of 4.21 ounces of
silver per tonne. The full dimensions of the mineral deposits at the San
Cristobal Project have not yet been determined; mineralized material extends
outward from the identified ore body in most directions as well as to depths
below 200 meters. The reserve estimates are limited by the current extent of
the Company's program of closely spaced drilling analysis. The Company will be
conducting an ongoing exploration program in order to fully delineate the
mineralized zones.
   
  The San Cristobal Study was prepared for the Company by Kvaerner Metals, Davy
Nonferrous Division ("Davy"), an international engineering procurement,
construction and management firm. Davy was also retained by the Company to
confirm independently the reliability of the Company's drilling and sampling
procedures at the San Cristobal Project. A more detailed summary of key
conclusions from the San Cristobal Study is provided elsewhere in this
Prospectus. See "Development Project--San Cristobal Project--First Phase
Feasibility Study Results".     
 
                                       1
<PAGE>
 
 
  All aspects of this confirmatory process were controlled by Davy, including
(i) the number of test holes required (four), site selection and drilling of
the four reverse circulation drill holes parallel to holes previously drilled
by the Company; (ii) sample collection, preparation and transportation; and
(iii) assay analysis. Davy's work confirmed results reported by the Company.
Behre Dolbear & Company Inc. ("Behre Dolbear"), a geological and mining
consulting firm, conducted a technical audit of and confirmed, within the
accuracy of plus or minus 25 to 30 percent, the work undertaken by Davy and the
other independent technical specialists who contributed to the San Cristobal
Study. The San Cristobal Study concluded with an economic assessment of the
identified mineral deposits.
   
  Based on the San Cristobal Study, the San Cristobal Project, as currently
delineated, is forecast to produce an average of 14 million ounces of silver,
132,700 tonnes of zinc and 39,500 tonnes of lead per year over the anticipated
11.5 year life of the project. The San Cristobal Project is expected to consist
of two large scale, open pit mining operations using conventional mining and
processing technologies capable of producing and processing an aggregate 30,000
tonnes per day ("tpd") of ore. The stripping ratio for open pit operations is
1.66 tonnes of waste for each tonne of ore. The average cash production cost
over the life of the San Cristobal Project is forecast to be $2.66 per silver
equivalent ounce. Capital expenditures are estimated to total $327 million for
pre-production development and construction to complete the San Cristobal
Project. Based on the favorable results of the San Cristobal Study, the Company
is targeting the completion of a second phase feasibility study of the San
Cristobal Project by the third quarter of 1998 with a goal of securing
committed financing by late 1998. Subject to the completion of a second phase
feasibility study and securing committed financing, the Company anticipates
beginning construction at the San Cristobal Project in early 1999, with silver,
zinc and lead production commencing in early 2001.     
 
  In addition, the Company's recent drilling at its Cobrizos property, located
approximately 12 kilometers north of the San Cristobal Project within the San
Cristobal district, has identified approximately 10.8 million tonnes of
mineralized material with an average grade of 4.3 ounces of silver per tonne.
The Company plans to conduct further drilling and engineering studies to
establish proven and probable reserves.
   
  The Company estimates that its San Cristobal district properties may contain
some of the largest known open pit silver, zinc and lead deposits in the world.
Based on the general geology of the San Cristobal district, the drilling and
analysis performed for the San Cristobal Study, and the amount of mineralized
material identified to date, the Company expects that the San Cristobal Project
could be extended in life and/or increased in scale.     
   
  There are certain specific risks associated with the San Cristobal Project,
and thus there can be no assurance that the Company will successfully develop
the San Cristobal Project. See "Risk Factors--San Cristobal Project Risks."
                                
                             OTHER PROPERTIES     
 
  The Company is currently evaluating three other advanced-stage exploration
properties: the El Ocote silver property in southwestern Honduras; the San Juan
de Lucanas silver and gold property in southern Peru; and the Choroma silver
prospect in southern Bolivia. At the El Ocote property, the Company has
completed a conceptual engineering study in order to determine the feasibility
of bringing the property into production. Based on the results of this study,
the Company is planning a comprehensive metallurgical sampling and test
program. Upon completion of the registration of its ownership of the San Juan
de Lucanas property, the Company will conduct a focused exploration and
evaluation program to establish and develop reserves by, among other things,
drilling targets identified
 
                                       2
<PAGE>
 
by previous exploration activities. Sampling of outcrops at the Choroma silver
prospect has defined several anomalies which the Company plans to drill to test
for bulk mineable mineralization and access existing underground workings for
further sampling.
   
  The Company controls a portfolio of silver properties covering more than two
million acres of mineral rights in eight countries. The Company has conducted
limited drilling and sampling at some of these other exploration properties and
anticipates that certain of these properties may contain significant silver
mineralization.

  The Company is one of a limited number of mining companies with a primary
focus on silver exploration, development and production. The Company's business
strategy is to capitalize on its sizeable reserve and mineralized material base
in order to achieve long-term profitable growth and enhance shareholder value.
The principal elements of the Company's business strategy are as follows: (i)
to complete a second phase feasibility study of a large scale open pit mining
operation at the San Cristobal Project; (ii) to secure the financing required
to develop the San Cristobal Project; (iii) to proceed to develop the San
Cristobal Project into a large scale open pit mining operation; (iv) to
continue exploration and evaluation activities at the Cobrizos property in
southern Bolivia, the El Ocote property in southwestern Honduras, the San Juan
de Lucanas property in southern Peru, and to commence drilling and underground
sampling at the Choroma property in Southern Bolivia; (v) to evaluate other
properties in the Company's portfolio of silver exploration properties,
focusing the Company's exploration and development efforts on those properties
which are most likely to contain significant silver mineralization and
divesting itself of those properties that are not of continuing interest to the
Company; and (vi) to identify and acquire additional mining and mineral
properties that the Company believes contain significant amounts of silver or
have exploration potential.
 
  The Company believes that its expanding international portfolio of
development and exploration properties position it to take advantage of future
increases in demand for silver and certain co-occurring minerals, such as zinc,
lead, copper and gold.
 
                               BUSINESS STRENGTHS
   
  The Company's substantial proven and probable reserves of silver, zinc and
lead, its additional significant silver, zinc, lead, copper and gold
mineralized material, its large exploration property portfolio and its
experienced management team position the Company to become a major precious and
base metals producer and to benefit from favorable developments in these
markets.     
 
MAJOR SILVER DEVELOPMENT PROJECT
   
  The San Cristobal Study indicates that the San Cristobal Project may
constitute one of the largest known mineable silver deposits in the world.
Based on the San Cristobal Study, two of the 15 mineralized deposits identified
at the San Cristobal Project are estimated to contain total proven and probable
reserves of 219 million ounces of contained silver as well as significant
amounts of zinc and lead. The San Cristobal Study indicates that production at
the San Cristobal Project could commence as early as 2001 at a rate of 30,000
tpd of ore producing on average 14 million ounces of silver, 132,700 tonnes of
zinc metal and 39,500 tonnes of lead metal, subject to the results of a second
phase feasibility study and securing the required financing. The San Cristobal
Study indicates that the nature and extent of the deposits at the San Cristobal
Project will enable the development of a large scale, open pit mining operation
with low stripping ratios that utilizes conventional mining and processing
technology, enabling the Company to benefit from economies of scale in
production.

DIVERSIFIED PORTFOLIO OF SILVER PROPERTIES
 
  The Company's current property portfolio is diversified not only in terms of
property location, but also in terms of stages of evaluation. The Company's
development, advanced exploration and other exploration stage mineral
properties are located primarily in or near traditional silver producing
regions in South America, Central America and Central Asia. These properties
include substantial holdings throughout southern Bolivia, northern Chile,
southwestern Honduras, southern Peru, and the Zacatecas district of Mexico, as
well as significant mineral concessions in Kyrghyzstan, Mongolia and
Tajikistan. Initial analyses of several of the Company's early-stage
exploration properties indicate the presence of sufficient silver
mineralization to warrant additional exploration and evaluation in order to
determine the potential for future development. Notwithstanding its primary
focus on silver, the Company intends to exploit, where economically feasible,
co-occurring minerals, such as zinc, lead, copper and gold, at its mineral
properties.
 
EXPERIENCED MANAGEMENT TEAM
 
  The management of the Company is comprised of an experienced team of mining
experts, whose experience in managing, identifying, developing, building and
bringing into production major mining enterprises averages approximately 30
years. In addition, many of the members of the Company's management team have
extensive experience in operating large scale mining projects for major
international mining companies throughout the world. Certain of the Company's
senior executives and the members of its Development Committee have had overall
responsibility for the development and operation of major mining operations,
including, among others, one major expansion of an existing iron ore mine
costing $170 million, two new mine developments each costing $165 million, the
operation and administration of major open pit iron and zinc/silver mines
located in Peru, the development, construction and start up of the $230 million
Muruntau gold project in Zarafshan, Uzbekistan, the $450 million (Australian)
Mount Keith open pit nickel mine, and participation in the identification of
several multi-million ounce gold deposits.
       
                                COMPANY HISTORY
 
  The Company was founded in 1993 to acquire and develop attractive silver
properties throughout the world. Since 1993, the Company has accumulated a
portfolio of silver exploration properties covering more than two million acres
in eight countries. These acquisitions were premised on several factors,
including (i) the low price of silver relative to the price of other precious
metals, (ii) a perception that silver supply and demand fundamentals were
stronger than the then-prevailing price of silver suggested, (iii) the general
scarcity of attractive publicly-traded silver companies and (iv) the perception
of negative sentiment within the traditional silver mining community.
 
  In December of 1994, in connection with an investment by Silver Holdings LDC
("Silver Holdings"), the Company reorganized as a Cayman Islands holding
company with regionally targeted subsidiaries. See "Corporate Structure",
"Certain Transactions" and "Principal Shareholders". Following this
reorganization and new investment, Apex Silver Mines LDC, an exempted limited
duration company organized under the laws of the Cayman Islands ("Apex LDC"),
accelerated its program of acquiring silver exploration properties. In March of
1996, in connection with a private placement of common stock (the "1996 Private
Placement"), Apex Limited was organized. The 1996 Private Placement, which was
completed as of August 6, 1996, raised gross proceeds of $34.1 million. See
"Certain Transactions".
 
  Apex Limited conducts all of its operations through Apex LDC and the
subsidiaries of Apex LDC; Apex Limited's assets consist exclusively of its
shares in Apex LDC. Prior to the Offering, Apex Limited owned approximately 66
percent of the issued and outstanding shares of Apex LDC; upon completion
 
                                       4

of the Offering (assuming the over-allotment options granted to the U.S.
Underwriters and Managers are not exercised), Apex Limited will own
approximately [   ] percent of the issued and outstanding share capital of Apex
LDC. Currently, Apex Limited has approximately 13,601,544 Ordinary Shares
outstanding and approximately 7,077,007 Ordinary Shares reserved for issuance
for approximately 7,077,007 shares of Apex LDC owned by the Minority
Shareholders. If all such shares of Apex LDC were issued, Apex Limited would
have 20,678,551 Ordinary Shares outstanding. See "Corporate Structure" and
"Certain Transactions".
 
                           ADDRESS, PRINCIPAL OFFICE
 
  The Company was formed under the laws of the Cayman Islands and maintains its
registered office at Caledonian House, Ground Floor, Mary Street, George Town,
Grand Cayman, Cayman Islands, British West Indies.
 
  The Company has contracted with Apex Silver Mines Corporation ("Apex
Corporation"), a wholly-owned subsidiary of Apex LDC, for certain management
services. Apex Corporation maintains its principal office at 1700 Lincoln
Street, Suite 3050, Denver, Colorado 80203.

                  RESERVES AND MINERALIZED MATERIAL DATA     
   
  The following table sets forth the Company's proven and probable reserves of
silver, zinc and lead as of August 29, 1997 at the San Cristobal Project. The
reserves reflected below are based on an equivalent cut-off grade of 1.0 ounce
of silver per tonne and prices of $5.00 per ounce for silver and $0.55 and
$0.30 per pound for zinc and lead, respectively. Proven and probable reserves
include an average recovery of 75.5 percent for silver, 78.0 percent for zinc
and 73.3 percent for lead. The proven and probable reserves and mineralized
material have been determined by Mine Reserves Associates Inc. ("MRA"),
independent consultants working as members of the first phase feasibility
consultants' team. Confirmation of the reserves and mineralized material was
also conducted by another independent consulting firm, Pincock, Allen & Holt
("PAH") which developed an independent resource grade model using a common data
set that checked closely with the reserve estimates. Davy and, separately,
Behre Dolbear acting as technical auditor, reviewed the reserve estimates and
confirmed the results reported below within the accuracy of the study. See
"Properties--Development Project--San Cristobal Project--Reserves and
Mineralized Material."

  The following table sets forth the Company's estimates of the silver, zinc
and lead mineralized material contained in its property portfolio. Mineralized
material is that part of mineral deposits for which (i) tonnage and grade are
computed (a) partly from specific measurements, samples or production data
compiled from assays of outcrops, trenches, underground workings or drill holes
and (b) partly from projections based on geological evidence, and (ii) have not
been measured and sampled with sufficient confidence to determine that the
identified deposit can be economically and legally extracted at the time of
such determination. The mineralized material estimates were determined by MRA
for the Tesorera and Jayula deposits, and by the Company with respect to the
other deposits. In the case of the Cobrizos deposit, the mineralized material
estimates were verified by MRA. In the case of the El Ocote deposit, the
mineralized material estimates were developed by the Company and reviewed by
Behre Dolbear.

                                 RISK FACTORS
 
  Prospective purchasers of the Shares offered hereby should consider
carefully, in addition to the other information contained in this Prospectus,
the following risk factors:
   
LIMITED OPERATING HISTORY; HISTORY OF LOSSES     
   
  The Company, incorporated in the Cayman Islands in March of 1996, is the
successor to the mineral property acquisition, exploration and development
activities conducted by its affiliates since 1993. The Company has incurred
losses since its inception, and expects to incur additional losses for at
least the next four years. As of June 30, 1997, the Company had an accumulated
deficit of $24,975,158. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations".     
 
RESERVE AND OTHER MINERALIZATION ESTIMATES
 
  The reserves and other mineralization figures presented herein, unless
otherwise indicated, are based on estimates of contained silver and other
metals made by independent geologists and/or the Company's personnel. These
estimates are imprecise and depend on geological interpretation and
statistical inferences drawn from drilling and sampling which may prove
unreliable. There can be no assurance that such estimates will be accurate, or
that indicated reserves or mineralization can be profitably exploited. Since
production has not yet commenced on any of the Company's properties, reserves
and other mineralization estimates for these properties may require
adjustments or downward revisions based on actual production experience. Any
material reductions in estimates of the Company's reserves and other
mineralization, or of the Company's ability to extract such reserves or
mineralization, could have a material adverse effect on the results of
operations and financial condition of the Company.
 
  The Company has completed a first phase feasibility study with respect to a
portion of only one of its properties, the San Cristobal Project. Accordingly,
the Company has not established the presence of any proven or probable
reserves at any of its other mineral properties. Although conceptual studies
have been prepared with respect to the Company's El Ocote and San Juan de
Lucanas exploration properties by independent parties using data and
assumptions provided by the Company, these studies involve assumptions and
projections based on a level of data insufficient to establish the presence of
proven or probable reserves. There can be no assurance that subsequent testing
or future feasibility studies will establish additional reserves at the
Company's properties. The failure to so establish additional reserves could
restrict the Company's ability to successfully implement its strategies for
long term growth.
 
  In addition, there can be no assurance that the proven or probable reserves
set forth in the San Cristobal Study will actually be able to be mined and
processed profitably, if at all. The San Cristobal Study is based on many
assumptions, any, some, or all of which may prove to be inaccurate. The
failure of any such assumptions to prove accurate may alter the conclusions of
the San Cristobal Study and may have a material adverse effect on the Company.
In addition, the economics of mining at San Cristobal are based on (i) bench
scale metallurgical testing of drill samples from the property to estimate
extraction yields of silver and other metals, (ii) estimates of the cost of
creating and operating the necessary mine process infrastructure and transport
facilities to profitably extract the minerals at the property and (iii)
estimates of the market price of silver, zinc and lead. Such estimates can be
highly inaccurate. There can be no assurance that the Company will achieve the
anticipated extraction rates or operating costs, or create the necessary
facilities within the budgets, proposed by the San Cristobal Study.
 
 
                                       8
<PAGE>
 
SAN CRISTOBAL PROJECT RISKS
 
  In addition to the other risk factors, the San Cristobal Project involves
the following risks:
 
  The proximity of the town of San Cristobal may adversely affect the
Company's ability to efficiently mine the San Cristobal Project. The Company
expects to seek to relocate the local population of approximately 350. There
can be no assurance that the Company will be able to develop an amicable and
economically feasible relocation program within the time period anticipated by
the Company's development plans. See "Properties--Development Project--San
Cristobal Project".
 
  Although the Company anticipates that the development of the San Cristobal
Project will be successfully completed and that the resulting operations will
be in full production by early 2001, no assurance can be given that the
development of the San Cristobal Project will be completed on a timely basis,
that the operations will achieve the anticipated production capacity or that
the construction costs or ongoing operating costs associated with the
development of the San Cristobal Project will not be higher than anticipated.
The construction of expanded mining operations involves a number of
uncertainties, including factors beyond the Company's control. Failure to
complete the development of the San Cristobal Project on a timely basis or
unexpected cost increases could have a material adverse effect on future
results of operations and financial condition of the Company. If the capital
expenditures required to complete the development of the San Cristobal Project
are significantly higher than expected, there is no assurance that the
Company's capital resources would be sufficient to cover such costs or that
the Company would be able to obtain alternative sources of financing to cover
such costs. See "Use of Proceeds" and "Properties--Development Project--San
Cristobal Project".
 
NO PRODUCTION HISTORY
 
  The Company has no history of silver production. The Company's strategy to
develop its economically feasible properties will require the construction or
rehabilitation and operation of mines, processing plants and related
infrastructure. As a result, the Company is subject to all of the risks
inherent in the establishment of new mining operations and business
enterprises. There can be no assurance that the Company will successfully
establish mining operations or profitably produce silver or other metals at
any of its properties.
 
MANAGEMENT OF GROWTH
 
  The Company anticipates that as its mineral properties are brought into
production and as it acquires additional mineral rights, it will experience
significant growth in its operations. This growth is expected to create new
responsibilities for management personnel, as well as added demands on the
Company's operating and financial systems. There can be no assurance that the
Company will be successful in meeting such demands and managing its
anticipated growth. The Company's growth is dependent, in part, on the
continued identification and acquisition of additional mineral rights. There
can be no assurance that the Company will be successful in acquiring
additional mineral rights.
   
VOLATILITY OF METALS PRICES; HEDGING ACTIVITIES     
 
  The profitability of the Company and its long-term viability are dependent
in large part on the market price of silver and other metals, including zinc
and lead. The market prices for such metals are volatile and are affected by
numerous factors beyond the Company's control, including expectations for
inflation, speculative activities, currency exchange fluctuations, global or
regional consumption patterns, supply of and demand for silver and the other
metals, political and economic conditions and production and transportation
costs. The aggregate effect of these factors is impossible for the Company to
predict and could have a material adverse effect on the Company and the
results of its operations.
 
                                       9
<PAGE>
 
  Certain mining operations, including the San Cristobal Project, may be
dependent upon anticipated proceeds from the production of secondary metals
and a decline in the price of any metals extracted by the Company could
materially adversely affect the profitability of the Company. If the market
price for these metals falls below the Company's production costs and remains
at such level for any sustained period, the Company will experience additional
losses and may determine to discontinue the development of a project or mining
at one or more of its properties. See "Metals Market Overview".
   
  The Company currently does not hedge against commodity and base metals price
risks. However, the Company anticipates that as its mineral properties are
brought into production and it begins to derive revenue from the production,
sale and exchange of commodity and base metals, the Company may utilize
various price hedging techniques to lock in forward delivery prices on a
portion of its production, and thereby mitigate some of the risks associated
with fluctuations in the prices of the metals it produces. The Company may
also engage in hedging activities to hedge the risk of exposure to currency
fluctuations as a result of its operations in several foreign countries. There
can be no assurance that the use of hedging techniques will always benefit the
Company. For example, there is the possibility that the Company will lock in
forward deliveries at prices lower than the market price at the time of
delivery. Such an event would negatively affect the Company's revenues and
profits. See "Management's Discussion and Analysis of Financial Condition and
Results of Operations".     
 
EXPLORATION AND DEVELOPMENT RISKS
 
  The degree of profitability of the Company's operations will be affected by
the costs and results of its continued exploration and development programs.
The Company is seeking to expand its reserves through a broad program of
exploration and development, including ongoing development activities at the
San Cristobal Project. Mineral exploration is highly speculative in nature,
involves many risks, and frequently is nonproductive. There can be no
assurance that the Company's mineral exploration efforts will be successful.
Once mineralization is discovered, it usually takes a number of years from the
initial phases of exploration until production is possible, during which time
the economic feasibility of production may change. Substantial expenditures
are required to establish ore reserves through drilling, to determine metal
content and metallurgical processes to extract such metal from the ore and, in
the case of new properties, to construct mining and processing facilities. As
a result of these uncertainties, no assurance can be given that the Company's
exploration programs will result in the establishment of new ore reserves.
 
  None of the Company's mineral properties have an operating history upon
which estimates of future cash operating costs may be based. Estimates of
reserves and cash operating costs, particularly for development projects, to a
large extent, are based upon the interpretation of geologic data obtained from
drill holes and other sampling techniques, and feasibility studies which
derive estimates of cash operating costs based upon anticipated tonnage and
grades of ore to be mined and processed, the configuration of the ore body,
expected recovery rates of silver and other metals from the ore, comparable
facility and equipment operating costs, anticipated climatic conditions, and
other factors. As a result, it is possible that actual cash operating costs
and economic returns may differ significantly from those currently estimated
by the Company. It is not unusual in new mining operations to experience
unexpected problems during the start-up phase.
 
  There are a number of uncertainties inherent in any development program,
including the location and dimensions of a deposit, metal content, development
of appropriate metallurgical processes, receipt of necessary governmental
permits and the construction of mining and processing facilities.
 
  The costs involved in building or upgrading all necessary power, water or
transportation facilities at any given property may be considerable,
particularly in light of the frequently remote locations of the Company's
properties. The development of many of the Company's properties will require
the
 
                                      10
<PAGE>
 
creation of extensive infrastructure in order to commence production at such
sites. No assurance can be given that minerals will be discovered in
sufficient quantities to justify commercial operations or that the funds
required for development can be obtained at all, or on a timely basis.
Accordingly, there can be no assurance that the Company's future development
activities or exploration efforts will result in profitable mineral
production.
 
TITLE TO MINERAL PROPERTIES
 
  Although it is the Company's policy to seek to confirm the validity of its
rights to title to, or contract rights with respect to, each mineral property
in which it has a material interest, there is no guarantee that title to its
properties will not be challenged or impugned. Title insurance generally is
not available, and the Company's ability to ensure that it has obtained secure
claim to individual mineral properties or mining concessions may be severely
constrained. The Company has not conducted surveys of all of the claims in
which it holds direct or indirect interests and, therefore, the precise area
and location of such claims may be in doubt. Accordingly, the Company's
mineral properties may be subject to prior unregistered agreements, transfers
or claims, and title may be affected by, among other things, undetected
defects. In addition, the Company may not be able to operate its properties as
permitted, or to enforce its rights with respect to such properties.
 
  The Company's rights to certain of its mineral properties, including certain
of its principal properties at the San Cristobal Project, derive from
leaseholds or purchase option agreements which require the payment of rent or
other installment fees. In the event the Company fails to make such payments
with respect to any of its mineral properties on the relevant due date, the
Company's rights to any such property may lapse. There can be no assurance
that the Company will, or will be able to, effect all such payments by the
requisite payment dates. In addition, certain of the Company's contracts with
respect to its mineral properties mandate development or production schedules.
There can be no assurance that the Company will be able to meet any or all of
such development or production schedules. In addition, the Company's ability
to transfer or sell its rights to certain mineral properties may require
governmental approvals or third party consents, which may not be granted.
 
  The Company's title to, and control over its San Juan de Lucanas property in
Peru has been contested by certain employee creditors of the prior operator of
the property. During the last three years, parts of the property have been
physically controlled by individuals challenging the Company's ownership.
There can be no assurance that the Company will prevail in its attempt to
register title to the property. See "Properties--Advanced Exploration
Properties--San Juan de Lucanas".
 
MINING RISKS AND INSURANCE
 
  The business of mining is generally subject to a number of risks and
hazards, including adverse environmental effects, industrial accidents, labor
disputes, technical difficulties posed by unusual or unexpected geologic
formations, cave-ins, flooding and periodic interruptions due to inclement or
hazardous weather conditions. Such risks can result in damage to and
destruction of, mineral properties or producing facilities, as well as
personal injury, environmental damage, delays in mining, monetary losses and
possible legal liability. Although the Company maintains, and intends to
continue to maintain, insurance with respect to its operations and mineral
properties within ranges of coverage consistent with industry practice, no
assurance can be given that such insurance will be available at economically
feasible premiums. Insurance against environmental risks (including potential
liability for pollution or other disturbances resulting from mining
exploration and production) is not generally available to the Company.
 
FOREIGN OPERATIONS
 
  The Company currently conducts exploration activities in countries with
developing economies, including Bolivia, Chile, Honduras, Mexico and Peru in
Latin America, and Kyrghyzstan, Mongolia and
 
                                      11
<PAGE>
 
Tajikistan in Central Asia. Each of these countries has experienced recently,
or is experiencing currently, economic or political instability.
Hyperinflation, volatile exchange rates and rapid political and legal change,
often accompanied by military insurrection, have been common in these and
certain other emerging markets in which the Company may conduct operations.
The Company may be materially adversely affected by possible political or
economic instability in any one or more of those countries. The risks include,
but are not limited to, terrorism, military repression, expropriation,
changing fiscal regimes, extreme fluctuations in currency exchange rates, high
rates of inflation and the absence of industrial and economic infrastructure.
Changes in mining or investment policies or shifts in the prevailing political
climate in any of the countries in which the Company conducts exploration and
development activities could adversely affect the Company's business.
Operations may be affected in varying degrees by government regulations with
respect to production restrictions, price controls, export controls, income
and other taxes, expropriation of property, maintenance of claims,
environmental legislation, labor, welfare benefit policies, land use, land
claims of local residents, water use and mine safety. The effect of these
factors cannot be accurately predicted.
 
GOVERNMENT REGULATION AND ENVIRONMENTAL MATTERS
 
  All commercial production and mineral exploration and development by the
Company will be subject to foreign laws and regulations controlling not only
the mining of and exploration for mineral properties, but also the possible
effects of such activities upon the environment. These laws and regulations
are comprehensive and deal with matters such as air and water quality, mine
reclamation, waste handling and disposal, the protection of certain species
and the preservation of certain lands. These environmental laws and
regulations may require the acquisition of permits or other authorizations for
certain activities. Environmental legislation is evolving in a manner which
will require stricter standards and enforcement, increased fines and penalties
for non-compliance, more stringent environmental assessments of proposed
projects and a heightened degree of responsibility for companies and their
officers, directors and employees. Permits from a variety of regulatory
authorities are required for many aspects of mine operation and reclamation.
The Company cannot predict what environmental legislation or regulations will
be enacted or adopted in the future or how future laws and regulations will be
administered or interpreted. Compliance with more stringent laws and
regulations, as well as potentially more vigorous enforcement policies or
regulatory agencies or stricter interpretation of existing laws, may
necessitate significant capital outlays, may materially adversely affect the
Company's future operations or may cause material changes or delays in the
Company's intended activities.
 
  The Company's preliminary analysis of the existing mining activities
conducted by the current owner and operator of the Toldos mine at the San
Cristobal Project indicates that low-level effluents from the site may be
draining into a seasonal stream which flows into the Rio Grande and,
ultimately, into the Salar de Uyuni, a salt lake to the north of the San
Cristobal Project. See "Properties--Development Project--San Cristobal
Project". Pursuant to the recently enacted Bolivian mining code, mining
companies are not liable for identified pre-existing conditions. Nonetheless,
if the Company acquires the Toldos property from its current owner, the
Company expects to improve the environmental situation which may currently
exist at the site. The Company does not expect any such remediation program to
have a material adverse effect on the Company's proposed operations at the San
Cristobal Project.
 
  Environmental conditions may exist on other mineral properties currently
owned or controlled by the Company which are unknown to the Company at present
and which have been caused by previous or existing owners or operators of the
properties. The Company has not sought an environmental analysis at any of its
mineral properties, nor has it conducted a comprehensive review of the
environmental laws and regulations applicable to it in each of the various
jurisdictions in which it owns or controls mineral properties. To the extent
the Company is subject to environmental liabilities, the satisfaction of such
liabilities would reduce the Company's net cash flow and could have a material
 
                                      12
<PAGE>
 
adverse effect on the Company's financial position and results of operations.
Should the Company be unable to fund fully the cost of remediation of any
environmental condition, the Company might be required to suspend operations
or enter into interim compliance measures pending completion of the required
remediation.
 
COMPETITION
 
  The mining industry is intensely competitive. The Company competes with many
companies possessing greater financial resources, operational experience and
technical facilities than itself. Competition in the mining business could
adversely affect the Company's ability to attract requisite capital funding or
acquire suitable producing properties or prospects for mineral exploration in
the future. The Company recently has encountered increasing competition from
other mining groups in its efforts to acquire mineral properties.
 
HOLDING COMPANY STRUCTURE RISKS
 
  The Company currently conducts, and will continue to conduct, all of its
operations through subsidiaries. The Company's ability to obtain dividends or
other distributions from its subsidiaries may be subject to, among other
things, restrictions on dividends under applicable local law and foreign
currency exchange regulations in the jurisdictions in which the subsidiaries
operate. The subsidiaries' ability to pay dividends or make other
distributions to the Company may also be subject to their having sufficient
funds from their operations legally available for the payment thereof which
are not needed to fund their operations, obligations or other business plans.
If the Company's subsidiaries are unable to pay dividends or make other
distributions to the Company, the Company's growth may be inhibited after the
proceeds of the Offering are exhausted, unless the Company is able to obtain
additional debt or equity financing on terms which are acceptable to the
Company. In the event of a subsidiary's liquidation, there may not be assets
sufficient for the Company to recoup its investment therein.
       
DISCRETION AS TO USE OF PROCEEDS
 
  Apex Limited will contribute the gross proceeds of the Offering, and all
associated expenses, to Apex LDC. While the Company has identified certain
anticipated uses for the net proceeds, it will have broad discretion as to the
expenditure of such proceeds.
 
REQUIREMENT OF ADDITIONAL FINANCING
 
  The net proceeds of the Offering will not be sufficient to complete the
Company's planned development of the San Cristobal Project. The Company
intends to seek additional financing to complete development of the San
Cristobal Project and to fund the development of other of its mineral
properties, including the Cobrizos, El Ocote, San Juan de Lucanas, and Choroma
properties. Sources of such external financing include bank borrowings and
future debt and equity offerings. There can be no assurance that additional
financing will be available on terms acceptable to the Company and its
shareholders, or at all. The failure to obtain such additional financing could
have a material adverse effect on the results of operations and the financial
condition of the Company.
 
  The operations contemplated by the Company are expected to be highly capital
intensive. There can be no assurance that the Company will be able to secure
the financing necessary to retain its rights to, or to begin, or, if begun, to
sustain production at the Company's mineral properties.
 
DEPENDENCE ON KEY PERSONNEL
 
  The Company is dependent on the services of certain key executives including
its Chairman and the Chief Operating Officer. The loss of these persons, other
key executives or personnel, or the
 
                                      13
<PAGE>
 
   
inability to attract and retain the additional highly skilled employees
required for the expansion of the Company's activities, may have a material
adverse effect on the Company's business or future operations. Although the
Chairman does not have a written contract certain key executives have entered
into written agreements. See "Executive Compensation--Employment Agreements".
The Company does not intend to maintain "key-man" life insurance on any of its
executive officers or other personnel.     
 
SUBSTANTIAL CONTROL BY DIRECTORS AND SIGNIFICANT SHAREHOLDERS
   
  Upon the completion of this Offering, Thomas S. Kaplan and the Company's
directors and principal shareholders, together with members of their families
and entities that may be deemed affiliates of or related to such persons or
entities, will beneficially own approximately [   ] percent of the Ordinary
Shares outstanding after the Offering, including approximately 7,077,007
Ordinary Shares which would be issued in the event the Company elected to
satisfy all of its obligations to the Minority Shareholders of Apex LDC
arising under the Buy-Sell Agreement through the issuance of Ordinary Shares.
See "Certain Transactions". Mr. Kaplan and others, together with certain of
the shareholders of Apex LDC, including Silver Holdings, have entered into an
agreement with respect to the appointment of two designees of Silver Holdings
to the Company's board of directors for so long as Silver Holdings owns one
percent of the outstanding Ordinary Shares, including Ordinary Shares it may
receive pursuant to the Buy-Sell Agreement. Silver Holdings' investors include
entities affiliated with Mr. Paul Soros and Mr. Eduardo Elsztain, who are
directors of the Company. In addition, Quantum Industrial Partners LDC and
Geosor Corporation, collectively own more than 50 percent of Silver Holdings.
By virtue of his ownership of Geosor Corporation and his position with Soros
Fund Management LLC, an investment advisor to Quantum Industrial Partners LDC,
Mr. George Soros may have the power to direct the election of the directors of
Silver Holdings, who in turn, will elect the two designees. See "Certain
Transactions". Such a high level of ownership by such persons may have a
significant effect in delaying, deferring or preventing a change in control of
the Company or other events which could be of benefit to the Company's other
shareholders. See "Principal Shareholders".     
 
CONFLICTS OF INTEREST
 
  Certain officers and directors of the Company are officers and/or directors
of, or are associated with, other natural resource companies that acquire
interests in mineral properties. Such associations may give rise to conflicts
of interest from time to time. See "Certain Transactions."
 
SUBSTANTIAL DILUTION
 
  As a result of the Offering, persons purchasing Shares in the Offering will
experience immediate and substantial dilution in the net tangible book value
per share of $[    ]. See "Dilution".
 
ABSENCE OF DIVIDENDS
 
  The Company does not anticipate paying dividends to existing or future
shareholders for the foreseeable future. It is the present intention of the
Company to retain all earnings, if any, in order to support the future growth
of its business. Any determination in the future to pay dividends will be
dependent upon the Company's consolidated results of operations, financial
condition, cash requirements, future prospects and such other factors as the
Company deems appropriate at the time.
 
NO PRIOR PUBLIC MARKET
   
  Prior to the Offering, there has been no public market for the Shares. An
application will be made to have the Shares listed for quotation on the
American Stock Exchange. There can be no assurance that an active public
market for the Shares will develop, or if such market does develop, be
sustained. The initial public offering price for the Shares will be determined
by negotiations among the Company and the underwriters. There can be no
assurance that the market price of the Shares after     
 
                                      14
<PAGE>
 
the Offering will equal or exceed the initial public offering price. The
market price of the Shares could be subject to significant fluctuations in
response to variations in quarterly operating results, developments relating
to the Company and general trends affecting the metals industry. In addition,
broad market fluctuations and general economic and political conditions may
adversely affect the market price of the Shares regardless of the Company's
performance. See "Underwriting" for a description of the factors to be
considered in determining the initial public offering price.
 
ORDINARY SHARES ELIGIBLE FOR FUTURE SALE
 
  Sales of substantial amounts of Ordinary Shares in the public market
following the Offering could adversely affect the market price of the Shares.
The Company and certain of its directors and executive officers, and all
current shareholders (including the shareholders of Apex LDC) have agreed,
during the 180 days following the date of the Prospectus, not to sell any
Ordinary Shares without the prior written consent of Salomon Brothers Inc
("Salomon"). See "Certain Transactions", "Ordinary Shares Eligible for Future
Sale" and "Underwriting".
 
TAX RISKS
 
  Potential investors should inform themselves as to the tax consequences of
acquiring, holding and disposing of Shares in their particular circumstances.
In particular, potential investors that are U.S. taxpayers should consider
that the Shares may be considered interests in a "passive foreign investment
company" ("PFIC") for U.S. tax purposes, and should consult their own tax
advisers as to the taxation of U.S. shareholders of PFICs in light of their
particular circumstances. If the Company were deemed to be a PFIC, then a U.S.
taxpayer who disposes or is deemed to dispose of Shares at a gain generally
would be required to treat such gain as ordinary income and pay an interest
charge on a portion of the gain unless the U.S. taxpayer makes a timely
election (a "QEF election") to have the Company treated as a "qualified
electing fund".
 
  A U.S. taxpayer who makes a QEF election generally must report on a current
basis his share of any ordinary earnings and net capital gain of the Company
for any taxable year in which the Company is a PFIC. A QEF election generally
must be made for the first taxable year of the U.S. taxpayer's ownership of
Shares during which the Company is a PFIC, provided that the Company complies
with certain reporting requirements. The Company intends to comply with all
reporting requirements necessary for U.S. investors to make QEF elections with
respect to the Company and will upon request provide to U.S. investors such
information as may be required to make such QEF elections effective. For
taxable years beginning after December 31, 1997, a U.S. investor who owns
marketable stock in a PFIC may elect to recognize gain or loss on a mark-to-
market basis in lieu of making a QEF election. For a further discussion, see
"Taxation--United States Federal Income Taxation--Passive Foreign Investment
Company Considerations".
 
FORWARD-LOOKING STATEMENTS
 
  This Prospectus contains forward-looking statements within the meaning of
Section 27A of the Securities Act of 1933, as amended (the "Securities Act"),
and Section 21E of the Securities Exchange Act of 1934, as amended (the

                                USE OF PROCEEDS
 
  The aggregate net proceeds to the Company from the sale of Shares offered
hereby are estimated to be approximately [$ . ] (or approximately [$ . ] if
the U.S. Underwriters' and the Managers' over-allotment options are exercised
in full) after deducting the underwriting discount and estimated fees and
expenses payable by the Company in connection with the Offering. The Company
intends to use the net proceeds for one or more of the following purposes: (i)
feasibility studies, financing, and construction and development of the San
Cristobal Project, (ii) exploration and development activities at any of the
other properties within the Company's existing portfolio, (iii) maintenance of
control or ownership of the Company's existing mineral properties by making
ongoing lease payments, and paying royalties and other maintenance and
registration fees, and (iv) acquisition of additional properties or businesses
that are complementary to those of the Company. In addition, the Company may
use the net proceeds for working capital and other general corporate purposes.
Apex Limited will contribute the gross proceeds from the Offering, and all
associated expenses, to Apex LDC in exchange for an equal number of Apex LDC
shares.
   
  Although the Company has not determined a specific allocation of proceeds
among the various uses described above, the Company currently estimates that
it will spend $10 million in 1998 in connection with the second phase
feasibility study, and an additional $10 million and $15 million,
respectively, for exploration activities at the San Cristobal Project and the
Company's other mineral properties over the next three years performing
reconnaissance, field managing and sampling, including drilling. The Company
expects to incur approximately $5 million per annum in general and
administrative expenses. The amounts actually expended on each of the uses
described above will vary depending upon, among other factors, the results of
the second phase feasibility study and the success of the Company's
exploration and development activities. Additional financing will be required
to fund future development activities and there can be no assurance that such
financing will be available at all, or on terms acceptable or favorable to the
Company and its shareholders. See "Risk Factors--Discretion as to Use of
Proceeds" and "--Requirement of Additional Financing".     
 
                                DIVIDEND POLICY
 
  The Company has never paid any dividends on its Ordinary Shares and expects
for the foreseeable future to retain all of its earnings from operations for
use in expanding and developing its business. Any future decision as to the
payment of dividends will be at the discretion of the Company's board of
directors and will depend upon the Company's earnings, receipt of dividends
from its subsidiaries, financial position, capital requirements, plans for
expansion and such other factors as the board of directors deems relevant. See
"Risk Factors--Absence of Dividends".

  As of June 30, 1997, the net tangible book value of the Company was
$13,163,995 or $1.00 per share outstanding. After giving effect to the sale of
the [   ] Shares offered hereby, deduction of the underwriting discount and
estimated expenses of the Offering payable by the Company and the application
of the net proceeds therefrom as set forth under "Use of Proceeds", the pro
forma net tangible book value of the Company as of June 30, 1997 would have
been [   ] or [   ] per share. This change represents an immediate increase in
net tangible book value of [   ] per share to existing shareholders and an
immediate dilution of [   ] per share to purchasers of the shares of the
Company's share capital at the initial public offering price. The following

                              CORPORATE STRUCTURE
 
HISTORY OF THE COMPANY
 
  Beginning in 1993, the Company and its founders embarked on a program of
acquiring silver exploration properties throughout the world. In December of
1994, in connection with an investment by Silver Holdings, the Company
reorganized as a Cayman Islands holding company with subsidiaries based on
regional operations. See "Certain Transactions". Following this reorganization
and new investment, Apex LDC accelerated its program of acquiring silver
exploration properties. In March of 1996, in connection with the 1996 Private
Placement, Apex Silver Mines Limited was organized. The 1996 Private
Placement, which was completed as of August 6, 1996, raised gross proceeds of
$34.1 million for an approximately 21 percent interest (on a fully diluted
basis) in the Company. See "Certain Transactions".
 
  As an "exempted" company under the laws of the Cayman Islands, the Company
may not carry on business in the Cayman Islands, except in furtherance of the
business of the Company carried on outside the Cayman Islands. Substantially
all of Apex Limited's assets consist of shares of Apex LDC. Currently, Apex
Limited owns approximately 66 percent of Apex LDC. Upon completion of the
Offering (assuming the over-allotment options granted to the U.S. Underwriters
and the Managers are not exercised), Apex Limited will own [   ] percent of
the outstanding share capital of Apex LDC. The Minority Shareholders are
entitled to sell their shares of Apex LDC to Apex Limited for, at Apex
Limited's sole option, Ordinary Shares on a one-for-one basis, cash, or a
combination of cash and Ordinary Shares. The Company currently expects that
any future purchases by Apex Limited of shares of Apex LDC from the Minority
Shareholders will involve only Ordinary Shares of Apex Limited. Any such
transactions will not affect the beneficial and economic interest in Apex LDC
attributable to shareholders of Apex Limited. Currently, Apex Limited has
approximately 13,601,544 Ordinary Shares outstanding and approximately
7,077,007 Ordinary Shares reserved for issuance for approximately 7,077,007
shares of Apex LDC owned by the Minority Shareholders. If all such shares of
Apex LDC were issued, Apex Limited would have 20,678,551 Ordinary Shares
outstanding. See "Principal Shareholders" and "Certain Transactions". Apex LDC
conducts its business primarily through a series of directly and indirectly
owned subsidiaries. The Company has approximately 33 full-time employees.
   
  Apex LDC's, and hence the Company's, principal operating subsidiaries are
(i) Andean Silver Corporation LDC ("Andean"), which is indirectly engaged in
exploration and development activities in South America; (ii) Apex Asia LDC
("Apex Asia"), which is engaged, directly and indirectly, in exploration
activities in Asia; (iii) Apex Corporation, which serves as the principal
management services provider to the Company pursuant to the terms of a
Management Services Agreement executed in connection with Apex Corporation's
formation in the fall of 1996; (iv) Minera de Cordilleras (Honduras), S. de
R.L. ("Cordilleras Honduras"), which is engaged in exploration and development
activities in Honduras; (v) Cordilleras Silver Mines Ltd. ("Cordilleras
Bahamas"), which is indirectly engaged in exploration and development
activities in Honduras; and (vi) Compania Minerales de Zacatecas, S. de R.L.
de C.V. ("CMZ"), which is indirectly engaged in exploration activities in
Mexico. See "Certain Transactions".     
   
  Apex LDC is the sole beneficial owner of Andean, with a 99 percent interest;
the remaining one percent interest is held by Apex Partners LDC ("Apex
Partners"), which is wholly beneficially owned by Apex LDC. Apex LDC is the
sole beneficial owner of ASC Bolivia LDC ("ASC Bolivia"), with a 2.5 percent
interest; the remaining 97.5 percent is held by Andean. Apex LDC is the sole
beneficial owner of ASC Peru LDC ("ASC Peru"); Andean holds a 99 percent
interest in ASC Peru, and ASC Partners LDC ("ASC Partners"), which is wholly
and beneficially owned by Apex LDC, holds the remaining one percent interest.
The Company anticipates that individual properties will be contributed to new
special purpose holding companies prior to the commencement of production at
such properties. The formation of such additional subsidiaries will not
involve any dilution to the Company's beneficial ownership of the underlying
properties.

<PAGE>
 
   
  Apex Asia, which is wholly beneficially owned by Apex LDC, has formed joint
venture entities to own or otherwise hold interests in silver resource
properties in Kyrghyzstan and Mongolia, and is in the process of doing so in
Tajikistan. In Kyrghyzstan, Apex Asia holds a 50 percent interest in " "JSC'
Kumushtak" ("Kumushtak Mining"). The remaining 50 percent interest in
Kumushtak Mining is held by the North Kyrghyz Geological Expedition, a
government mining enterprise which operates in the Kumushtak region in
northwestern Kyrghyzstan. Apex Asia owns 99 percent of Kumushtak Management
Company; Apex Partners holds the remaining one percent. In Mongolia, Apex Asia
has organized "Asgatmongu' Company, Ltd. ("Asgat Mining"). Apex Asia holds
approximately one half of the total interests in Asgat Mining and has
appointed two individuals, including the chairman, of Asgat Mining's four
member board of managers. Mongolrostvetmet, a joint association owned by the
government of Mongolia and Zarubeshvetmet, a recently privatized company
organized under the laws of the Russian Federation, holds the remaining
interest in Asgat Mining. In Tajikistan, Apex Asia has entered into an
agreement with the Adrasman Mining Venture ("Adrasman Mining"), an agency of
the government of Tajikistan, to form "Kanimansur Ltd." Joint Mining Venture
("Kanimansur Mining"). Kanimansur Mining will be 49 percent owned by Apex
Asia.     
   
  In Mexico, CMZ serves as the holding company for Compania Metalurgica Largo,
S. de R.L. de C.V. ("Largo"), Compania Metalurgica Barones, S. de R.L. de C.V.
("Barones") and Minera de Cordilleras, S. de R.L. de C.V. ("Cordilleras
Mexico"). Apex LDC is the sole beneficial owner of CMZ, with a 99 percent
interest; Apex Partners holds the remaining one percent interest. Apex LDC is
the sole beneficial owner of Cordilleras Mexico; CMZ holds a 99 percent
interest and Apex Partners holds the remaining one percent interest. Barones
and Largo are each owned 75 percent by CMZ and 25 percent by Minera Dolore
Anguatias y Anexas, S.A. de C.V., an unaffiliated Mexican company.     
          
  Apex LDC is the sole owner of each of Cordilleras Bahamas and Apex
Corporation. Apex LDC is the sole beneficial owner of Cordilleras Caymans with
a 20 percent interest; the remaining 80 percent interest is held by
Cordilleras Bahamas. Apex LDC is the sole beneficial owner of Cordilleras
Honduras, with a 99 percent interest; the remaining one percent interest is
held by Apex Partners.

   MANAGEMENT'S DISCUSSION AND ANALYSIS OFFINANCIAL CONDITION AND RESULTS OF
                                  OPERATIONS
 
GENERAL
 
  The following discussion and analysis should be read in conjunction with the
Consolidated Financial Statements and related notes thereto which appear
elsewhere in this Prospectus.
   
  The Company is a mining exploration and development company that holds a
portfolio of silver exploration and development properties in South America,
Central America and Central Asia. None of these properties are in production
and, consequently, the Company has no current operating income or cash flow.
    
BACKGROUND
 
  In mid-1993, Apex Silver Mines Ltd. ("Apex Bermuda") was established to
acquire and develop silver exploration properties throughout the world.
 
  On December 22, 1994, Apex Bermuda contributed substantially all of its
assets to Apex LDC, a limited duration company formed under the laws of the
Cayman Islands.
 
  In March of 1996, Apex Limited, a limited liability company formed under the
laws of the Cayman Islands, was incorporated in order to facilitate the 1996
Private Placement. In connection with the 1996 Private Placement, Apex Limited
issued Ordinary Shares to certain of the non-U.S. investors in Apex LDC in
exchange for their interests in Apex LDC. These transactions, and the 1996
Private Placement were completed effective as of August 6, 1996. Currently,
Apex Limited owns approximately 66 percent of Apex LDC. Upon the completion of
the Offering (assuming the over-allotment options granted to U.S. Underwriters
and the Managers are not exercised) Apex Limited will own [   ] percent of the
outstanding share capital of Apex LDC. The Minority Shareholders are entitled
to sell their shares of Apex LDC to the Company for, at Apex Limited's sole
option, Ordinary Shares of Apex Limited on a one for one basis, cash, or a
combination of cash and Ordinary Shares. The Company currently expects that
any future purchases by Apex Limited of shares of Apex LDC from the Minority
Shareholders will involve only Ordinary Shares. Any such transactions will not
affect the beneficial and economic interest in Apex LDC attributable to
shareholders of Apex Limited. See "Certain Transactions". Currently, Apex
Limited has approximately 13,601,544 Ordinary Shares outstanding and
approximately 7,077,007 Ordinary Shares reserved for issuance for
approximately 7,077,007 shares of Apex LDC owned by the Minority Shareholders.
If all such shares of Apex LDC were issued, Apex Limited would have 20,678,551
Ordinary Shares outstanding.
 
  For United States investors, ownership of the Shares may have certain tax
consequences. See "Tax Considerations".
 
THE SAN CRISTOBAL PROJECT
   
  From 1994 to 1996, the properties comprising the San Cristobal Project were
acquired in a series of transactions. See "Properties--Development Project--
San Cristobal Project." In 1996, the Company began exploring these properties,
and discovered the presence of a significant silver zinc and lead deposit with
the potential to be developed as a large scale open-pit mining project. In the
fall of 1996, an in-fill drilling program using reverse circulation ("RC") and
diamond core drilling was continued in order to delineate the deposit and the
amount of reserves. In addition, an expanded exploration effort at the San
Cristobal Project resulted in the discovery of additional silver and base
metal anomalies.     
 
  Based on the San Cristobal Study, the San Cristobal Project is forecast to
produce annually an average of 14 million ounces of silver, 132,700 tonnes of
zinc and 39,500 tonnes of lead during an expected minimum life of 11.5 years.
The San Cristobal Project is expected to consist of two large
 
                                      22
<PAGE>
 
   
scale, open pit mining operations using conventional mining and processing
technologies capable of producing and processing an aggregate 30,000 tonnes
per day ("tpd") of ore. The average cash production cost over the life of the
San Cristobal Project is forecast to be $2.66 per silver equivalent ounce. See
"Glossary". Capital expenditures are estimated to total $327 million for pre-
production development and construction to complete the San Cristobal Project.
Based on the favorable results of the San Cristobal Study, the Company is
targeting the completion of a second phase feasibility study of the San
Cristobal Project by the third quarter of 1998 with a goal of securing
committed financing by late 1998. Subject to the completion of a second phase
feasibility study and committed financing, the Company anticipates beginning
construction at the San Cristobal Project in early 1999, with silver, zinc and
lead production commencing in early 2001.     
 
  The Company plans to commission this second phase feasibility study in the
fall of 1997, immediately after the completion of the Offering. The Company
also intends to continue an extensive drilling program in order to (i) further
define the existing ore bodies, (ii) increase the San Cristobal Project's
proven and probable reserves and (iii) evaluate other areas of potential
mineralization. At the same time, contracts for power supply, transportation,
and smelting and refining of metal concentrates will be negotiated.
 
  If the results of this second phase feasibility study confirm the economic
feasibility of the San Cristobal Project, and if no new properties emerge in
the interim that are considered to be more attractive development
opportunities, the Company expects to devote the majority of the proceeds from
the Offering to financing its equity portion of the construction and
development costs of the San Cristobal Project. See "Use of Proceeds".
 
  The Company has retained N.M. Rothschild & Sons Limited and Barclays Bank
PLC as the Company's financial advisor and arranger, respectively, in
connection with the anticipated project financing of the San Cristobal
Project. The Company anticipates that project financing activities will
commence on a preliminary basis in late 1997 and then accelerate with the
delivery of the a second phase feasibility study in mid-1998 with financing to
be secured by late 1998. If this timetable is achieved, project construction
could commence in early 1999 and, after an approximate two-year construction
and development program, production could commence in early 2001.
 
  The Company has engaged Salomon and Credit Suisse First Boston Corporation
("Credit Suisse First Boston") to act as the Company's financial advisors with
respect to the identification of, and negotiation with, potential joint
venture mining partners in the San Cristobal Project. The Company has paid
each of Salomon and Credit Suisse First Boston a financial advisory fee and
has agreed to pay each of them monthly advisory fees and a success-based
transaction fee, and to reimburse their respective out-of-pocket expenses. In
addition, the Company has agreed to indemnify each of Salomon and Credit
Suisse First Boston against certain liabilities.
 
OTHER PROJECTS
 
  The Company is also assessing the economic viability of (i) the Cobrizos
property in Bolivia, which may be developed in conjunction with the San
Cristobal Project; (ii) the El Ocote project in Honduras; (iii) the San Juan
de Lucanas project in Peru; and (iv) the Choroma property in Bolivia.
 
  The Cobrizos property is located approximately 12 kilometers north of the
San Cristobal Project. Recent drilling by the Company suggests the presence of
approximately 10.8 million tonnes of mineralized material containing 4.3
ounces of silver per tonne and 0.2 percent copper. This mineralized material
estimate has been reviewed and verified by MRA, an independent mine geology
consulting firm. The mineralized body is amenable to open pit mining and is
being considered as a satellite mining operation that could provide additional
feed to the proposed mill to be constructed at the San Cristobal Project,
thereby enhancing the silver grade of the ore processed by the mill after the
early years of operation at the San Cristobal Project.
 
                                      23
<PAGE>
 
  The El Ocote property is located in southeast Honduras. Behre Dolbear
reviewed the Company's estimate that the property contains approximately 2.1
million tonnes of mineralized material averaging 9.9 ounces of silver per
tonne and prepared a conceptual study of this property for the Company in
1996. On the basis of this initial study, the Company conducted further field
work and a second conceptual study. This latest study, which was performed by
Davy, utilized the earlier resource estimates, and estimated new capital and
operating costs and production schedules based on underground mining and heap
leach processing. The Company expects to conduct an additional round of field
work and to undertake metallurgical sampling and heap leach tests. If
warranted, these analyses will be followed by additional drilling to establish
proven and probable reserves.
 
  In June of 1995, PAH prepared a conceptual study for the rehabilitation of
an idled mine at the San Juan de Lucanas property. The results indicated that
approximately $10 million in capital expenditures would be required to
rehabilitate the mine to a 500 tpd capacity operation. The Company believes
that the identification of additional reserves at the site would be required
to justify such an investment. In addition, the Company has experienced
lengthy delays in its effort to register its title to the properties
comprising the San Juan de Lucanas property. While the Company believes its
legal position is secure, it is not currently possible to estimate when this
registration process will be completed. The Company expects to begin
exploration and commission a first phase feasibility study of the property
after its title thereto has been perfected.
 
  The Choroma property is located in the Bolivian silver-lead belt, 600
kilometers south of La Paz and 80 kilometers north of the Argentine border
near the town of Tupiza at an elevation of approximately 3,300 meters. During
early 1996, the Company channel-sampled many of the rock outcrops and
identified several anomalies 44 to 86 meters long with average grades between
1.8 and 4.0 ounces of silver per tonne. These anomalies will be drilled and
sampled to test for bulk mineable mineralization. In addition, the Company
will gain access to existing underground workings to sample these structures,
and to test further for bulk mineralization.
 
RESULTS OF OPERATIONS
 
  Loss Before Minority Interest. The Company does not produce silver or any
other mineral products and has no revenues from product sales. The only source
of revenue is interest income. The loss before minority interest for the six
month period ended June 30, 1997 was $11,177,495 compared to a loss before
minority interest of $5,990,521 for the six month period ended June 30, 1996,
and the loss before minority interest for the year ended December 31, 1996 was
$14,599,240 compared to a loss before minority interest of $3,354,160 in 1995
and a net loss before minority interest of $403,149 in 1994. The Company's
expenses for the year ended December 31, 1996 were substantially higher than
1995 and 1994 due to increased exploration activity and higher general and
administrative expenses.
 
  Exploration. Mineral exploration expenditures are expensed as incurred prior
to the determination of the feasibility of mining operations. Once it has been
determined that a mineral property has proven and probable ore reserves,
subsequent development and exploration expenses are capitalized. Through June
30, 1997, all acquisition and exploration costs have been expensed as
incurred. The Company will capitalize future exploration and development costs
associated with the San Cristobal Project commencing with the start-up of the
second phase feasibility study.
 
  Exploration expenses were $7,961,583 for the six month period ended June 30,
1997 compared to $4,322,867 for the six month period ended June 30, 1996, and
were $9,590,632 for the year ended December 31, 1996, compared to $1,559,874
in 1995 and $105,185 in 1994. The increased exploration expenses from 1995 to
1996 were due to an increase in exploration activity at the San
 
                                      24

Cristobal Project. Total cumulative exploration expense at the San Cristobal
Project was [$   ] through June 30, 1997.
 
  Administrative. Administrative expenses were $1,814,480 for the six month
period ended June 30, 1997, compared to $497,874 for the six month period
ended June 30, 1996, and totaled $1,923,165 for the year ended December 31,
1996, compared to $982,261 in 1995 and $147,780 in 1994. The increased
expenditures in 1996 relative to 1995 were primarily due to the hiring of key
management personnel during the second half of 1996 and the opening of Apex
Corporation's Denver office.
 
  Consulting. Consulting fees were $1,059,669 for the six month period ended
June 30, 1997 compared to $792,417 for the six month period ended June 30,
1996, and were $2,506,250 for the year ended December 31, 1996, compared to
$560,060 in 1995 and $144,840 in 1994. The increase in 1996 over 1995 is
primarily due to expenses associated with retaining third party consultants to
prepare technical studies on various properties and executive recruiters to
identify and hire key personnel.
 
  Professional Fees. Professional fees were $775,863 for the six month period
ended June 30, 1997, compared to $421,055 for the six month period ended June
30, 1996, and totaled $1,096,271 for the year ended December 31, 1996,
compared to $657,621 in 1995 and $20,600 in 1994. The increase in 1996 over
1995 was primarily due to higher legal and accounting fees.
 
  Amortization and Depreciation. Amortization and depreciation expense was
$41,198 for the six month period ended June 30, 1997, compared to $28,295 for
the six month period ended June 30, 1996, and totaled $57,392 for the year
ended December 31, 1996, compared to $56,591 in 1995 and $-0- in 1994. Costs
incurred in the organization of the Company and its subsidiaries were
capitalized and are being amortized on a straight-line basis over five years.
 
  Interest Income. The primary source of income for the Company since
inception is interest income. Interest income for the six month period ended
June 30, 1997 was $475,298 compared to $71,987 for the six month period ended
June 30, 1996, and totaled $574,470 for the year ended December 31, 1996,
compared to $462,247 in 1995 and $15,256 in 1994. The Company's policy is to
invest all excess cash in liquid, high credit quality, short term financial
instruments. The increase in interest income for the comparative periods was
due to the additional cash raised in the 1996 Private Placement.
 
  Income Taxes. Apex Corporation, the Company's U.S. management services
company, is subject to U.S. income taxes. Otherwise the Company pays no income
tax in the U.S. since the Company is incorporated in the Cayman Islands and
conducts no business that currently generates U.S. taxable income. There is
currently no corporate taxation imposed by the Cayman Islands. If any form of
taxation were to be enacted in the Cayman Islands, the Company has been
granted exemption until January 16, 2015. See "Tax Considerations".
 
EMPLOYEE BENEFITS
 
  The Company does not provide any post-retirement or post-employment benefits
to its employees and therefore does not accrue for such expenses. In 1997,
Apex Corporation instituted a 401(k) Plan for its U.S. employees. Apex
Corporation makes monthly contributions to this 401(k) Plan, and currently
matches 50 percent of each employee's contribution up to an employee
contribution of six percent of base salary. Employees vest in the Company's
contribution at 50 percent after one year of service and 100 percent after two
years of service. Although the Company does not currently have a formal bonus
or incentive plan for any of its employees, it anticipates instituting a bonus
plan in the future. See "Executive Compensation--Other Plans".

LIQUIDITY AND CAPITAL RESOURCES
 
  As of June 30, 1997, the Company had cash and short-term investments of
$13,088,342 compared to $25,949,771 at December 31, 1996 compared with
$3,296,618 at December 31, 1995 and $356,942 at December 31, 1994. The
increase in 1996 relative to 1995 was due primarily to the receipt of net
proceeds from the 1996 Private Placement and the payment of the Silver
Holdings demand note discussed below.
 
  On December 22, 1994, the Company received, in consideration for the
issuance of shares of Apex LDC to Silver Holdings, a $10,000,000 non-
negotiable demand note, with interest accrued thereon at an interest rate
equal to the one month London Interbank Offered Rate for U.S. dollar deposits.
The principal outstanding under this demand note was $2,819,718 on December
31, 1995 and $9,250,000 on December 31, 1994. On February 5, 1996, the
remaining balance was fully paid. See "Certain Transactions".
 
  In connection with the 1996 Private Placement, which closed effective August
6, 1996, the Company issued 4,256,700 Ordinary Shares at a price of $8.00 per
share and received net proceeds of $32,449,350.
 
  The net cash used in operating activities for the six month period ended
June 30, 1997 was $12,981,766 compared with $4,938,517 for the six month
period ended June 30, 1996, and was $12,091,580 for the year ended December
31, 1996, compared with $3,490,631 in 1995 and $328,586 in 1994. The variance
in the net cash used in operating activities between the comparative periods
was due to the increased exploration activity and the San Cristobal Study. The
net cash provided by financing activities was $171,659 for the six month
period ended June 30, 1997, compared with $2,819,718 for the six month period
ended June 30, 1996, and $35,269,068 for the year ended December 31, 1996,
compared with $6,430,307 in 1995 and $685,528 in 1994.
 
  The Company is subject to a series of obligations with respect to its
mineral properties; the failure to meet any of these commitments could result
in the loss or forfeiture of one or more of the Company's properties. These
obligations consist of government mineral patent fees and commissions, work
commitments, lease payments and advance royalties. In addition, a number of
the Company's property interests derive from contractual purchase options. In
order to acquire such properties, the Company will be obliged to make certain
payments to the registered concession holders and others who have interests in
the properties. See "Notes to the Consolidated Financial Statements".
 
  The Company does not currently have a line of credit with any financial
institution.
 
  The Company's future revenues and earnings will be influenced by currency
exchange rates and by world market prices for silver, zinc, lead, copper and
gold, which fluctuate and over which the Company has no control. See "Metals
Market Overview". Depending upon market conditions for currency exchange and
metal prices, the Company may from time to time hedge its metal or currency
exposure in order to decrease fluctuations in revenues and earnings. The
Company does not currently have a set of policies or guidelines for hedging
foreign currency, interest rate or metals price exposure. See "Risk Factors--
Volatility of Metals Prices".
 
  The Company does not know of any trends, demands, commitments, events or
incidents that may result in the Company's liquidity either materially
increasing or decreasing at present or in the foreseeable future other than
the Offering.
 
  It is anticipated that the Company will devote the majority of the net
proceeds from the Offering to financing its equity portion of the San
Cristobal Project's construction and development. In addition, it is
anticipated that significant expenditures will be made for other continuing
exploration, property acquisition, property evaluation and general corporate
expenses.
 
                                      26

  The development program at the San Cristobal Project will require
significant additional financing. Sources of financing may include bank
borrowings and future additional debt or equity financings. There can be no
assurance that any such financing will be obtainable on terms that are
attractive to the Company, or at all. The Company has retained N.M. Rothschild
& Sons Limited and Barclays Bank PLC to act as the Company's financial advisor
and arranger, respectively, in connection with the anticipated project
financing for the San Cristobal Project.
 
  The Company has engaged Salomon and Credit Suisse First Boston to act as the
Company's financial advisors with respect to the identification of, and
negotiation with, potential joint venture mining partners in the San Cristobal
Project. The Company has paid each such financial advisor a financial advisory
fee and has agreed to pay each of them monthly advisory fees and a success-
based transaction fee, and to reimburse their respective out-of-pocket
expenses. In addition, the Company has agreed to indemnify each financial
advisor against certain liabilities.
 
  As of the date hereof, the Company does not plan to declare or pay a
dividend.
 
ENVIRONMENTAL COMPLIANCE
 
  The Company's current and future mining and processing operations and
exploration activities will be subject to various federal, state and local
laws in the countries in which it conducts its activities, which govern the
protection of the environment, prospecting, development, production, taxes,
labor standards, occupational health, mine safety, toxic substances and other
matters. Management does not believe that compliance with such regulations
will have a material adverse effect on its competitive position. The Company
intends to obtain all licenses and permits required by all applicable
regulatory agencies in connection with its mining operations and exploration
activities. The Company's preliminary analysis of the previous and temporarily
continuing leaching operations at the Toldos mine operated by the current
owner and operator indicates that some effluents from the site may be draining
into a seasonal stream which flows into the Rio Grande and, ultimately, into
the Salar de Uyuni, a salt lake to the north of the San Cristobal Project.
Under Bolivian law the Company is not obliged to remediate known pre-existing
environmental conditions. Nonetheless, if the Company acquires the Toldos
property from its current owner, the Company expects to improve the
environmental situation which may currently exist at the Toldos property. The
Company does not expect any such program to have a material adverse effect on
the Company's proposed operations at the San Cristobal Project. The Company
intends to maintain standards of environmental compliance consistent with
World Bank environmental guidelines. See "Properties--Development Property--
San Cristobal Project".
   
METALS PRICE AND CURRENCY HEDGING ACTIVITIES     
          
  Currently, the Company's major principal cash balances are held in U.S.
dollars. Subsidiary cash balances in foreign currencies are held to minimum
balances and therefore have a minimum risk to currency fluctuations. There are
currently no hedge positions against foreign currencies. The Company currently
does not hedge commodity and base metals price risks. However, the Company
anticipates that as its mineral properties are brought into production and it
begins to derive revenue from the production, sale and exchange of commodity
and base metals, the Company may utilize various price hedging techniques to
lock in forward delivery prices on a portion of its production, and thereby
mitigate some of the risks associated with fluctuations in the prices of the
metals it produces. The Company may also engage in hedging activities to hedge
the risk of exposure to currency fluctuations as a result of its operations in
several foreign countries. There can be no assurance that the use of hedging
techniques will always benefit the Company.

                                  THE COMPANY
 
  The Company is engaged in the exploration and development of silver
properties in South America, Central America and Central Asia. The Company
believes it has accumulated one of the largest privately controlled portfolios
of silver exploration properties in the world. Since 1993, the Company has
acquired the rights to or gained control of 27 non-producing silver properties
located in or near the traditional silver producing regions of Bolivia, Peru,
Chile, Honduras, Mexico, Kyrghyzstan, Mongolia and Tajikistan. Exploration
efforts since 1993 have successfully produced the Company's first development
project, the San Cristobal Project located in southern Bolivia, where regular
and close spaced drilling and analysis has delineated substantial proven and
probable reserves of silver, zinc and lead. In addition, exploration
activities at the Company's other properties in Bolivia, Peru and Honduras
indicate the presence of significant quantities of mineralized material
containing silver and other metals.
 
  The San Cristobal Study was completed in August of 1997 with respect to the
San Cristobal Project, which is located in the Potosi department in southern
Bolivia, a region that has historically produced a significant portion of the
world's silver supply.
 
BUSINESS STRATEGY
 
  The Company was founded in 1993 to acquire and develop attractive silver
properties throughout the world. Since 1993, the Company has acquired a
portfolio of silver properties covering approximately two million acres in
eight countries. These acquisitions were premised on several factors,
including (i) the low price of silver relative to the price of other precious
metals, (ii) a perception that silver supply and demand fundamentals were
stronger than the then-prevailing price of silver suggested, (iii) the general
scarcity of attractive publicly-traded silver companies, and (iv) the
perception of negative sentiment within the traditional silver mining
community. As a consequence of a prolonged depressed price for silver, which
culminated in a low of $3.51 per ounce in 1993, many marginal silver producers
around the world were forced to scale back, and in some cases shut down, their
silver mining operations. The resultant mine closures, bankruptcies and low
prices contributed to a generally depressed market for silver mining
properties around the world. Competition for the purchase of silver properties
was further dampened by the fact that many of the silver mining companies that
maintained operations became less aggressive in their search for new silver
properties and/or attempted to diversify into other metals in order to
mitigate their exposure to low silver prices. Negative sentiment among silver
producers was reflected in reduced exploration expenditures. The Company's
founders believed that these market conditions provided the Company with
compelling opportunities to purchase silver exploration properties at
attractive prices.
 
  While this "bear market" psychology resulted in a soft market for silver
properties, the Company believed that the fundamental outlook for silver was
improving. The trend of large annual surpluses in silver supply relative to
demand, which had peaked in the early 1980s, began to reverse by the early
1990s, when rising industrial demand for silver, combined with declining
production profiles, caused substantial supply deficits. The Company believed
that the disequilibrium in supply and demand suggested that the "bear market"
in silver was nearing an end. Encouraged by what it considered a discrepancy
between market perceptions and improving fundamentals, the Company embarked on
a program of acquiring silver exploration properties globally and recruiting a
professional management team with a proven track record of developing and
operating mining properties worldwide.
 
  The Company believes that it has successfully achieved the objectives of its
initial acquisition program by assembling a portfolio comprised of
approximately 27 non-producing silver properties covering more than two
million acres of land located in or near traditional silver mining regions of
South
 
                                      28
<PAGE>
 
America, Central America and Central Asia. Moreover, the Company has recruited
an experienced management team with significant experience in the
identification, exploration and development of mineral properties, as well as
the construction and operation of large-scale mining projects. Finally, the
Company has successfully enlisted the support of major financial institutions
and investors through two private placements: a $10 million offering in
December of 1994, and a $34.1 million offering in August of 1996.
 
  Upon completion of the Offering, the Company will focus on achieving the
following five objectives: (i) to complete a second phase feasibility study of
a large scale open pit mining operation at the San Cristobal Project; (ii) to
secure the financing required to develop the San Cristobal Project; (iii) to
proceed to develop the San Cristobal Project into a large scale open pit
mining operation; (iv) to continue exploration and evaluation activities at
the Cobrizos property in southern Bolivia, the El Ocote property in
southwestern Honduras, the San Juan de Lucanas property in southern Peru, and
to commence drilling and underground sampling of the Choroma property in
Southern Bolivia; (v) to evaluate other properties in the Company's portfolio
of silver exploration properties, focusing the Company's exploration and
development efforts on those properties which are most likely to contain
significant silver mineralization and divesting itself of those properties
that are not of continuing interest to the Company; and (vi) to identify and
acquire additional mining and mineral properties that the Company believes
contain significant amounts of silver or have exploration potential.

<PAGE>
 
                                  PROPERTIES
 
  The Company's portfolio of silver properties in Bolivia, Peru, Chile,
Honduras, Mexico, Kyrghyzstan, Mongolia and Tajikistan, which cover an area in
excess of two million acres, contain identified silver mineralization or offer
significant exploration potential. These mineral properties consist of (i)
mining concessions which the Company has acquired, or is in the process of
acquiring, directly; (ii) concessions which the Company has leased, generally
with an option to purchase; (iii) concessions which the Company has agreed to
explore and develop and, if feasible, bring into production, in concert with
local joint venture partners; and (iv) new claims, principally to mineral
properties which the Company believes offer significant exploration
opportunities and which the Company has staked on its own behalf.
 
  The Company's exploration and development activities are currently focused
on five properties: the San Cristobal Project and the Cobrizos property in
southern Bolivia, the El Ocote property in southwestern Honduras, the San Juan
de Lucanas property in southern Peru, and the Choroma property in southern
Bolivia. All five of these properties remain subject to various stages of
exploration, analysis and development. The Company has completed a first phase
feasibility study with respect to the San Cristobal Project. Based on the
favorable results of the San Cristobal Study, the Company is targeting the
completion of a second phase feasibility study of the San Cristobal Project by
late 1998. The Company expects to commission a conceptual study with respect
to the Cobrizos property in the second half of 1997, and expects to commission
a drilling and underground sampling program of the Choroma property. The
Company has completed conceptual studies with respect to the El Ocote and San
Juan de Lucanas properties. Although the San Cristobal Project remains the
Company's top development priority, the initial analysis from the Cobrizos, El
Ocote, San Juan de Lucanas and Choroma properties have been promising and the
Company believes that these properties may be economic development and
production candidates.
 
  In addition to the aforementioned properties, the Company controls a
portfolio of silver exploration properties located in eight countries in South
America, Central America and Central Asia. The Company generally seeks to
structure its acquisitions of mineral rights so that individual properties can
be explored without significant expense and acquired if significant
development opportunities are identified. Properties which the Company
determines do not warrant further exploration or development expenditures will
be sold or otherwise relinquished, typically without further financial
obligation to the Company. Although the Company believes that its exploration
properties may contain significant silver mineralization, the Company's
analysis of such properties is at a preliminary stage. The activities
performed to date at these properties often have involved the analysis of data
from previous exploration undertaken with respect to a property, as
supplemented by the Company's own field work and sampling programs. See "Risk
Factors -- Reserve and Other Mineralization Estimates".

                              DEVELOPMENT PROJECT
 
SAN CRISTOBAL PROJECT
 
 Location and Access
 
  The San Cristobal Project is located in the San Cristobal district of Nor
Lipez province in the Potosi department in southern Bolivia, approximately 500
kilometers south of La Paz and 90 kilometers south of the town of Uyuni. The
San Cristobal Project is named after the town of San Cristobal which is
situated in the midst of the project area. The San Cristobal Project is
comprised of 15 separate identified mineralized anomalies, including the
Toldos deposit, which has been recently mined.
 
  The town of San Cristobal is accessible by a gravel road which runs
approximately 50 kilometers north to the railroad at Rio Grande and a further
60 kilometers northeast to Uyuni. A small unpaved airstrip is also located
approximately six kilometers from the Toldos deposit. The Company has
constructed unpaved roads to access the individual deposits at the site. The
Company anticipates that prior to the commencement of operations at the San
Cristobal Project it will be necessary to construct an approximately 53
kilometer rail spur and road linking the site to the existing main rail line
siding located 40 kilometers north of the property. The Company also expects
(i) to construct a 110 kilometer electric line to supply power to the San
Cristobal Project, and (ii) to pump water approximately ten kilometers to the
site from wells which will be drilled near the Rio Grande river.
 
  The property is largely undisturbed, except for the Toldos deposit, which
has been mined by underground block caving and open pit mining. At present,
there is no significant plant or equipment on site. There is an active mining
camp at the Toldos deposit. A small river, the Rio Grande, passes
approximately 11 kilometers south of the site. Due to the remote location and
small size of the town of San Cristobal, the Company expects that it will have
to recruit skilled and unskilled labor from neighboring areas.
 
 Operating History
   
  Silver was discovered in what is now the San Cristobal district in the early
seventeenth century, and mining has occurred intermittently in the area ever
since. Although no records from the Spanish colonial era mines have survived,
and few records exist with respect to production in the district during the
nineteenth and twentieth centuries, the Company estimates that the district
has produced in excess of 60 million ounces of silver. The Toldos mine was
operated as a block caving underground operation between 1985 and 1988, and
was operated as an open pit mine between 1989 and 1995. Empresa Minera Yana
Mallcu, S.A. ("Yana Mallcu"), a Bolivian mining corporation, continues to
operate a remnant heap leaching operation at Toldos, reprocessing the tailings
from the former mining operation.     
 
 Title and Ownership Rights
 
   Since commencing its acquisition program in the San Cristobal district, the
Company has secured contract rights over, outright ownership of or the first
claim of all of the mineral properties that it has identified to be of
interest within a radius of approximately 50 kilometers from the San Cristobal
Project.
   
  In October of 1994, the Company, acting through its agent Mineria Tecnica
Consultores Asociados ("Mintec"), entered into lease and option agreements
with the owner of ten mining concessions pertaining to approximately 1,134
acres of mineral rights including the mineralized areas known as Jayula and
Tesorera. In September of 1997, the Company exercised its option to purchase
these mining rights. The exercise price was $600,000, plus $12,000 per month
for the first 81 months, and $8,000 for the 82nd month, following exercise.
    
  In August of 1995, the Company, again acting through its agent Mintec,
acquired a two-year purchase option for the mining concessions containing the
Animas deposit from Cooperativa Minera
 
                                      31
<PAGE>
 
   
Litoral Ltda. ("Litoral"), a Bolivian mining cooperative. In July of 1997, the
Company exercised its option to purchase these mining concessions. The
acquisition price was $150,000, less 50 percent of the aggregate prior monthly
payments to Litoral.     
 
  In February of 1996, the Company, again acting through its agent Mintec,
acquired from Yana Mallcu an option to acquire mining concessions controlling
approximately 4,692 acres of mineral rights in the San Cristobal district,
including the entire Toldos mineralized dome. Under the terms of this option
agreement, which expires in February of 1998, the Company has agreed to pay
$6,000 per month to Yana Mallcu for the duration of the contract or until such
time as the Company exercises its option to purchase the concessions. The
Company is entitled to purchase the concessions for the sum of $500,000 and
the assumption of up to $5,750,000 of Yana Mallcu's indebtedness.
 
  The Company has engaged Salomon and Credit Suisse First Boston to act as the
Company's financial advisors with respect to the identification of, and
negotiation with, potential joint venture mining partners in the San Cristobal
Project.
 
 Geology and Mineralization
 
  The San Cristobal Project occupies the central portion of a volcanic
depression probably resulting from the collapse of a Miocene age volcanic
peak. The collapse resulted in the formation of a four kilometer diameter
depression, which was subsequently filled with fine to coarse-grained
volcaniclastic sedimentary rocks (shale, conglomerate, sandstone, landslide
debris, talus, etc.).
   
  In the late Miocene age, after sedimentation had nearly filled the
depression, a series of dacite and andesite porphyry sills and domes intruded
into the volcaniclastics, with disseminated and stockwork silver-lead-zinc
mineralization forming both within the volcaniclastics and in the intrusions
themselves. As a result, mineralization occurs in the San Cristobal district
in shallow intrusive dacite sills and domes, intrusive breccia bodies and
volcaniclastics. The disseminated mineralization has not been mined in the
past except for some areas of the Toldos mine. Previous workings were only on
mineralized veins. Company studies indicate the presence of at least 16
mineralized intrusive bodies, all located in close proximity to one another.
Most of the identified mineralized intrusive bodies are hydrothermally altered
and all have been found to be strongly mineralized. Nine of these intrusive
bodies have been drilled by the Company. To date, drilling has been conducted
in sufficient detail to allow estimates of proven and probable reserves at the
Tesorera and Jayula domes and additional mineralized material at Tesorera,
Jayula, Animas and Toldos domes. As previously noted, the Company currently
controls the mineral rights to all of these intrusive bodies.     
 
  The following paragraphs describe the geology and mineralization of the more
intensely drilled areas of the San Cristobal district. The two largest
identified areas of mineralization, the Jayula and Tesorera deposits, appear
to be portions of one single mineralized body, and even though they will be
identified separately below, recent drilling results suggest that the two
bodies may be connected with ore grade mineralization. The Company intends to
analyze these and other areas in conjunction with the overall exploration and
development plans for the San Cristobal Project.
 
  Jayula. The Jayula deposit consists of a dacite porphyry sill intruded into
volcaniclastics that filled the depression. Both the dacite intrusion and the
adjacent sediments have been cut by numerous narrow veins and veinlets,
forming a mineralized stockwork over large areas. Mineralization in the
stockwork consists of iron oxides, clays, galena, barite, sphalerite, pyrite,
tetrahedrite, and acanthite. Veins and veinlets are most common in the dacite
sill, near its contact with the sedimentary rocks. Within the volcaniclastics
rocks themselves, and locally within the intrusive sill, is a second form of
mineralization, characterized by disseminated galena, sphalerite and
acanthite. This disseminated mineralization is predominately confined to
coarser-grained sedimentary beds, usually conglomerates and coarse sandstones.
As the extent of ore grade mineralization is confined to the limits of the
planar beds of coarse-grained units, the mineral zones within the sediments
are both stratiform and
 
                                      32
<PAGE>
 
stratibound, forming gently-dipping planar bodies of mineralization which
parallel the bedding of the sediments.
 
  Oxidation of the mineralized zone in the Jayula deposit has occurred to a
depth averaging 40 meters. In this oxide zone, zinc has been nearly completely
leached out; silver values, however, are greatly enhanced due to secondary
enrichment processes. In the oxide zone, the dominant minerals are iron
oxides, clays, native silver, and secondary acanthite.
 
  Based on the assay results of samples taken from old small scale underground
workings, surface exposures, and seven diamond core and 50 RC holes drilled by
the Company, the Company believes that the dacite porphyry intrusion hosts
approximately 75 percent of the mineralization identified at Jayula, with the
volcaniclastics hosting the remainder. The mineralized zone at Jayula covers
an area no less than 500 meters by 600 meters on the surface, and ore grade
mineralization extends to at least 200 meters below the surface. Of the 57
holes drilled at Jayula, approximately one-half had ore-grade mineralization
at their lowest depth. The mineralized zone has not been fully delineated by
the drilling, with ore grade mineralization over significant widths being
found at the southeast, west and northwest perimeters of the drilled area and
at depth. The exploration program has delineated the boundaries of the deposit
only at the northeast corner of the deposit.
 
  Tesorera. The Tesorera deposit is 1,300 meters southwest of the Jayula
deposit, and both appear to be part of the same large mineralized system. The
geology and mineralization at Tesorera are nearly identical to Jayula. At
Tesorera, the west side of the deposit consists of a dacite porphyry sill
intruded into the caldera-fill sediments, and, as at Jayula, disseminated
mineralization occurs within certain coarse-grained sedimentary beds and in
the intrusion itself. This mineralization is similarly stratabound and
stratiform, forming several subparallel, gently-dipping horizons parallel to
the bedding of the volcaniclastics. The mineralogy is identical to that at
Jayula, consisting of pyrite, iron oxides, barite, clays, galena, sphalerite,
tetrahedrite, and acanthite.
 
  Oxidation has affected the Tesorera deposit to a greater depth than at the
nearby Jayula deposit, typically extending to a depth of 75 meters. The oxide
zone mineralogy of Tesorera, like that at Jayula, is dominated by iron oxides,
clays, native silver, and secondary acanthite.
 
  The Tesorera deposit has been drilled by 139 RC and ten diamond core holes
have been drilled at the Tesorera deposit. The assays indicate that the
mineralization is present over an area of 950 meters by 450 meters. As at
Jayula, the deposit is open to depth and in three directions but it is closed
to the west, as the dacite intrusion appears to have received minimal
mineralization. Approximately 40 percent of the holes had ore-grade
mineralization at their lowest depth, which was usually in excess of 200
meters below the surface.
 
  Animas. The Animas deposit, located two kilometers west of Tesorera, is
hosted by a subvertical breccia pipe adjacent to a stockwork-veined rhyolite
porphyry dike. The volcaniclastic rocks are not present at Animas, and thus
stratibound mineralization is absent.
 
  The breccia pipe occurs along the eastern margin of a north-trending
rhyolite dike. The pipe follows the margin for a distance of 400 meters, and
varies from 20 meters to 200 meters wide. It has been drilled to a depth of
200 meters, and is found to be shaped in cross section like an inverted cone
that is narrower at depth. Mineralization is primarily sulfide and consists of
massive galena and sphalerite as a matrix around the breccia fragments. Silver
is present as acanthite and minor tetrahedrite. The Company has drilled 33
reverse circulation holes at Animas.
 
  Toldos. The Toldos deposit consists of a series of a parallel, high-angle
veins. These veins were mined to a depth of approximately 100 meters below the
surface. These veins averaged approximately 15 ounces of silver per tonne. The
wall rock adjacent to the veins also contained disseminated
 
                                      33
<PAGE>
 
and veinlet mineralization. The Company believes that the wall rock and lower
grade ore has not been systematically mined.
 
  Yana Mallcu converted its operations at the Toldos dome from underground
narrow vein mining to bulk mining methods, principally block caving in 1985
and open pit mining in 1989. Beginning in 1985, ore was processed through a
conventional heap leaching circuit at a rate of 3,000 tonnes per day. With the
exception of some minor leaching of the mine tailings undertaken by the former
owner of the Toldos mine, mining activities at the Toldos deposit were
discontinued in 1995.
 
 Drilling Program
 
  The Company has been engaged in a comprehensive delineation and in-fill
drilling program at the San Cristobal Project since October of 1996. This
program was designed to substantiate initial positive drill results at several
of the numerous intrusive dacite or breccia domes located in the district and
has concentrated on the Tesorera, Jayula, and Animas mineralized dome
complexes. The Company has drilled 278 reverse circulation drill holes and 17
diamond core drill holes for a total of 64,554 meters of reverse circulation
RC drilling and 4,752 meters of diamond core drilling at the San Cristobal
Project. These drill holes were generally spaced at intervals from 25 up to
150 meters. Although this drilling is sufficient to establish the presence of
proven and probable ore reserves at the Tesorera and Jayula deposits, drilling
has been too widely spaced to establish proven and probable reserves at the
Animas deposit. The following table summarizes the Company's drilling
activities at San Cristobal.

 First Phase Feasibility Study
 
  In early 1997, the Company commissioned Davy to conduct the San Cristobal
Study. This first phase feasibility study was completed in August of 1997 and
has estimated accuracies ranging from plus or minus 25 to 30 percent. Davy
served as lead engineers, and reviewed the efforts and contributions of the
other independent San Cristobal Study consultants. MRA performed ore reserve
estimates using kriging estimating methods and prepared mine production
schedules, and estimated capital and operating costs. PAH developed an
independent resource grade model using the same database used by MRA which
checked closely with the MRA reserve estimates. Mineral Resource Development
Inc. ("MRDI") conducted the metallurgical test work and developed the process
flow sheet. Knight Piesold LLC was contracted to perform the preliminary
environmental assessment and geotechnical estimates, including mill tailings
pond design. The firm of Behre Dolbear was hired by the Company to conduct and
oversee a technical audit of Davy's procedures and analyses as well as the
work of the technical subcontractors. CPM Group ("CPM") was retained by the
Company to provide an independent analysis of the silver, lead and zinc
markets. The Company purchased published studies from Brook Hunt & Associates
and the International Lead Zinc Study Group regarding the lead and zinc
markets.
 
  Proven and probable reserve estimates are based on regularly spaced drilling
at the Tesorera and Jayula mineralized domes. Proven and probable reserves
were calculated using (i) the cost
 
                                      34
<PAGE>
 
assumptions delineated in the San Cristobal Study (see below) and (ii) the
market price assumptions of $5.00 per ounce of silver, $0.55 per pound of zinc
and $0.30 per pound of lead. The cut-off grade was based on a combined value
of $4.18 per tonne of ore. The ore reserve estimation method used was kriging,
a method which automatically moderates exceptionally high grades consistent
with the geostatistical character of its mineralization. The following table
summarizes the estimated proven and probable reserves and mineralized material
at the San Cristobal Project, as indicated by the drilling completed to date.
The reserve estimates for the Tesorera and Jayula deposits were prepared by
the San Cristobal Study consultants, and check closely with an independent
resource grade model developed by PAH. The additional mineralized material
which occurs proximate to the San Cristobal Project was estimated by MRA for
the Tesorera and Jayula deposits and the others were estimated by the Company.
The Company's Mineralized Material estimates with respect to the Cobrizos
deposit were confirmed by MRA.

Sampling Procedures
   
  The approximate 30 kilograms of RC drill cuttings from every two meters of
drill depth were sampled at the drill site by splitting the drill chips
ejected from the drill in a Vezin Sampler. This splitting process and the
moisture content of the ejected material results in approximately one-half of
the sample being collected in plastic buckets placed in series. The pulp is
allowed to settle and the excess water decanted off the sample. The sample is
then reslurried and split in half using a Jones type riffle sample splitter.
Each half is then placed in a sample bag and most of the remaining water is
allowed to drain for one to two days. One sample is sent to an assay
laboratory for sample preparation and analysis; the second sample is stored
for later reference and possible confirmatory testing. Drill core samples are
prepared by first sawing the core in half with a rock saw. Half of the core is
bagged for assay and the other half is used for geological logging and then
saved. These samples are also taken at intervals of approximately every two
meters of the drill core, depending upon rock type changes.     
 
  The six-kilogram RC drilling samples and the half core samples received at
the lab are first dried in an oven at a temperature not to exceed 85 degrees
centigrade. After drying, the samples are first crushed to minus ten (-10)
mesh (1.68 millimeters) and split in half. One of these samples is pulverized
to minus 65 mesh and again this is mixed and split down to 250 to 500 grams
using Jones type riffles. The remaining sample is bagged as a reserve. The
sample is then pulverized in a ring and puck pulverizer to minus 200 mesh
(0.074 millimeters).
 
                                      35
<PAGE>
 
  The minus 200 mesh sample is analyzed for silver using standard fire assay
procedures using a one assay tonne sample size. Samples with low silver values
are finished by atomic adsorption while samples with high silver values are
finished gravimetrically. Assay results are reported in parts per million
(grams per tonne). The sample is also analyzed for lead and zinc using
standard total wet analytical methods using a four acid digestion and atomic
adsorption. Results are reported in parts per million or percent, depending
upon the values encountered.
 
  Davy conducted its own independent drilling sampling and assay analysis of a
representative sample of four drill holes. Davy independently determined how
many holes and their positioning and managed the drilling of these four "twin"
holes, the collection of the resultant drill samples, and maintained custody
of the samples from the drill site to their independent assay laboratory in
the United States. This independent test program confirmed the Company's
drilling results.
 
 First Phase Feasibility Study Results
   
  The San Cristobal Study was based on field work involving extensive drilling
with typically evenly spaced drill holes designed to establish the presence
and dimensions of measurable mineralization. The Company's field work was
conducted in accordance with generally accepted mining industry procedures. In
addition, bench scale metallurgical test work was conducted. A fair and
accurate summary of key conclusions from the San Cristobal Study is provided
below.     
 
  Production Rates
 
  The first phase feasibility study utilized a base case incorporating an ore
production rate of 30,000 tonnes per day (10.8 million tonnes per year)
resulting in a minimum mine life of 11.5 years based on current reserves. An
average waste to ore strip ratio of 1:66:1 is indicated with the ratio varying
from approximately 2.0:1 in the early years to 0.5:1 in the later years of the
mine life. The ore is near the surface and outcrops in some areas and the
study estimates 30 million tonnes of pre-production waste stripping will be
required. Production will utilize conventional large scale open pit mining
methods and equipment.
 
  Processing
 
  The bench scale metallurgical tests and analysis indicate successful use of
conventional flotation separation of waste rock from minerals and separate
collection of silver rich zinc and lead concentrates for both oxide and
sulfide ores. Test results indicate average metallurgical recovery rates of 77
percent for silver, 85 percent for zinc and 75 percent for lead in the
sulphide ores, and 60 percent for silver and 55 percent for lead in the oxide
ores. These concentrates are expected to have metal content well within the
norms of downstream smelting and refining processes. Consequently, the process
selected by the study includes conventional primary crushing, followed by
semi-autogenous-grinding (SAG) milling, followed by differential flotation
which will produce separate zinc and lead concentrates each containing
approximately half of the silver produced.
 
  Metal in Concentrate Production
 
  The profile of the production of metals contained in concentrate is
estimated below.

  Cost Estimates
   
  Mine site cash production costs for mining, including stripping waste,
processing, overhead, reclamation, and general and administration costs are
estimated to be $6.33 per tonne of ore mined. These estimates assume the use
of a large scale mining contractor who will drill, blast, and transport the
ore and waste rock from the mine to the process plant and waste rock piles.
Average transport costs for concentrate produced to the market is estimated to
be $70 per tonne of concentrate from the mine gate. Treatment charges for
smelting and refining are estimated to be $175 per tonne of lead and zinc
concentrates.     
   
  Stripping ratio for the combined open pit operation is 1.66 tonnes of waste
for each tonne of ore. The cash production cost is estimated to be $2.66 per
equivalent ounce of silver.     
   
  Capital cost estimates for the completion of the second phase feasibility
study and financing, which the Company anticipates will be completed in late
1998, as well as the development and construction of mining, processing and
infrastructure and the inclusion of working capital, which the Company
anticipates will be completed in late 2000, total $327 million. This amount
includes $15 million of working capital, $24 million of pre-construction
capital, $26 million pre-production waste stripping, $262 million for the
construction of the process plant and necessary infrastructure. The process
plant and infrastructure estimates include a 20 percent contingency. These
estimates include the construction of transportation facilities and other
requisite infrastructure, but exclude the cost of mobile mining equipment
which will be provided by a mining contractor.     
 
  Proposed Development Program
 
  In the event no new properties emerge in the interim which represent more
attractive development opportunities, it is anticipated that the Company will
devote the majority of the proceeds from the Offering to develop the San
Cristobal Project.
 
  Part of the continuing development of the San Cristobal Project will be the
completion of a second-phase feasibility study. This study, and the field work
required in connection with it will involve:
 
  . Additional in-fill and extension drilling intended to delineate
    significant additional proven and probable reserves;
 
  . Sterilization drilling to confirm surface plant and infrastructure
    siting;
 
  . Collection of bulk and composite samples for additional bench scale and
    pilot plant scale metallurgical test work;
 
  . Comprehensive environmental sampling and monitoring including the
    preparation of an environmental impact study;
 
  . Discussions and negotiations with national and international service
    providers with respect to power supply and transportation, and
    negotiations with smelters and refiners of metal concentrates;
 
  . Collection of detailed and extensive cost information from national and
    international sources;
 
  . Preliminary engineering for mine, plant, and infrastructure to be
    advanced to approximately ten percent of final engineering so as to
    provide capital and operating cost estimates within an accuracy range of
    plus or minus ten percent; and
 
  . Continuing updates of metal markets dynamics and forecasts.
 
  The Company has retained N.M. Rothschild & Sons Limited and Barclays Bank
PLC as the Company's financial advisor and arranger, respectively, in
connection with the anticipated project financing of the San Cristobal
Project. The Company anticipates that project financing activities will
commence on a preliminary basis in late 1997 and then accelerate with the
delivery of the
 
                                      37
<PAGE>
 
second phase feasibility study in mid-1998 with financing to be secured by
late 1998. If this timetable is achieved, project construction could commence
in early 1999 and, after an approximate two-year construction and development
program, production could commence in early 2001.
 
 Exploration and Development
 
  Jayula. The Company plans to continue drilling the Jayula deposit in order
to determine the limits of economic mineralization. As the deposit is open in
most directions, and at depth, such drilling is required to determine the full
size of the deposit for pit design and mine planning. Preliminary drilling
west of the Jayula deposit indicates that the deposit may converge with the
Tesorera deposit, thus this probability will be tested by numerous closely
spaced drill holes.
 
  Tesorera. The Company intends to continue drilling the Tesorera deposit in
order to determine the full extent of the mineralization. A primary goal is to
determine the extent of mineralization, particularly toward the Jayula
deposit, to test the probability that the ore-grade mineralization at the
Tesorera deposit is indeed connected to that at the Jayula deposit, 1,300
meters to the northeast. Additional deep drilling will be conducted to
determine the depth of the mineralization at Tesorera, as many of the holes
have bottomed in ore grade mineralization.
 
  Animas. The Animas deposit is relatively small in comparison to the Tesorera
and Jayula deposits. Therefore, although much additional drilling is necessary
to put the mineralized material into a proven and probable category, drilling
at the site will likely take a lower priority than drilling at the other,
larger deposits. There is good exploration potential at the Animas deposit,
especially to the west of the rhyodocite dike, and to the north on strike of
the known breccia pipe. During routine district-wide exploration, these
potential areas will be tested.
   
  Cobrizos. Cobrizos is a joint venture between the Company and the
Corporacion Minera de Bolivia S.A. ("Comibol"), a government agency, and is
described in more detail below. Nevertheless, it is included under this
heading as its proximity to the San Cristobal Project makes it likely that it
will be developed in conjunction with the San Cristobal Project. Therefore,
future work will include drilling along strike beyond the currently defined
zone of mineralization, and diamond drilling to confirm the results of
reserve-circulation drilling as well as gather samples for metallurgical
testing. See "Advanced Exploration Properties--Cobrizos".     
 
  Toldos. The Company has started drilling reconnaissance holes in the area at
the Toldos deposit. Several of these holes show favorable results, and
additional drilling will be conducted to test the mineralized material for
proven and probable reserves.
 
  Satellite Deposits, including Inca, Colon, and Cerillos. In addition to the
above, the Company has additional anomalous zones in this area that it will
explore during the second phase feasibility study.
 
 Environmental and Other Issues
 
  The Company's preliminary analysis of the existing tailings operations at
the Toldos deposit at the San Cristobal Project indicates that some effluents
from the Toldos deposit may be draining into a seasonal stream which drains
into the Rio Grande and, ultimately, flows into the Salar de Uyuni, a salt
lake to the north of the San Cristobal Project. If the Company exercises its
option to acquire the Toldos property from its current owner, the Company
expects to improve the environmental situation which may currently exist at
the mine. The Company does not expect any such program to have a material
adverse effect on the Company's proposed operations at the San Cristobal
Project. See "Risk Factors--Government Regulation and Environmental Matters".
 
                                      38
<PAGE>
 
  The Company has determined that the town of San Cristobal, its church, and
its cemetery are located in close proximity to the planned Jayula and Tesorera
pits. The Company's efficiency when mining the deposits may be limited without
the resettlement of the residents of the town and the possible replacement of
its church. The Company is currently working with the residents of the town,
which it estimates has approximately 350 inhabitants, to develop an
economically feasible relocation plan sensitive to the interests of the
residents and the traditions of the town. See "Risk Factors--San Cristobal
Project Risks".

COBRIZOS
 
 Location and Access
 
  The Cobrizos property is located on level terrain 12 kilometers north of the
San Cristobal Project in southern Bolivia. The proximity to the San Cristobal
Project affords significant potential operating efficiencies. The former
railroad maintenance town of Uyuni lies 70 kilometers to the northeast and the
railroad to the Chilean port of Antofagasta, 460 kilometers distant, passes 20
kilometers to the north. The Bolivian commercial centers of Oruro and La Paz,
respectively, are located 350 kilometers and 500 kilometers to the north.
 
 Operating History
 
  Green and blue colored copper carbonate minerals were produced from the
deposit for use as pigment during pre-Columbian times and Spanish miners
subsequently engaged in small scale native copper and copper sulfate mining.
Between 1892 and 1906 Compania Arenal sank shafts as deep as 60 meters and
produced copper from approximately 100,000 tonnes of material extracted from
shallow underground and open cast workings. A combination of flooding and
carbon dioxide build-up in the workings ultimately forced a cessation of
operations.
 
 Title and Ownership Rights
 
  The Company acquired the right to enter into a joint venture with Comibol on
its approximately 4,178 acres of mining rights at the Cobrizos property
through public tender in August of 1996. An agreement defining the joint
venture was signed on September 11, 1996. Pursuant to this agreement, the
Company must complete certain payments and work commitments in order for its
rights to vest in this joint venture at the Cobrizos property, to which
Comibol contributes only the mining rights. These obligations are summarized
below.

  Comibol will receive five percent of the operating cash flow, as defined
below, from production at the Cobrizos property until the Company has
recovered its entire capital investment; thereafter, Comibol will receive 15
percent of operating cash flow. The Company has the right, in its discretion,
to reduce the acreage subject to the joint venture agreement prior to
commencement of the third year thereof and again prior to the commencement of
the fifth year thereof. Operating cash flow is defined in the agreement as the
gross revenues less the cost of transportation, smelting and refining,
marketing commissions, production costs and administrative expenses. Financing
costs and depreciation are not deductible from gross revenues.
 
 Geology
 
  The Cobrizos property hosts an oxidized copper-silver deposit of the red
bed-type composed of narrow (less than ten centimeters thick) veins in a
stockwork cutting shale and sandstone of the Jurassic Potoco Formation, which
dips steeply to the east.
 
 Mineralized Material
 
  In November and December of 1995, prior to entering into the aforementioned
joint venture agreement with Comibol, the Company conducted initial field
studies including geologic mapping and
 
                                      40
<PAGE>
 
   
the collection of 108 samples for geochemical analysis of gold, silver, and
copper. After successfully bidding for and acquiring the Cobrizos property,
the Company conducted a mercury vapor survey over the greater mineralized area
in August of 1996. In October of 1996, the Company drilled 11 inclined (-60
degrees) RC holes. Four of the holes drilled in a row 700 meters long and
spaced no less than 150 meters apart tested a single stratigraphic horizon and
intersected silver and copper mineralization.     
 
  These drill results precipitated a follow-up drilling phase focused on this
single stratographic horizon during which eight additional holes were drilled
over a strike length of 850 meters which, together with the four earlier
holes, resulted in all the drill holes being spaced approximately 75 meters
apart. The results indicate a steeply dipping mineralized zone with an average
width of 55 meters over the 855 meters of strike length. The indicated depth
from surface or near surface is at least 100 meters. The Cobrizos property
contains mineralized material of 10.8 million tonnes at an average grade of
4.3 ounces of silver per tonne and approximately 0.22 percent of copper. These
estimates were confirmed by MRA.
 
 Exploration and Development
 
  The Company intends to commission a conceptual study of the property in the
fall of 1997. Further drilling will be conducted in order to increase the
reliability of current data, to determine the limits of the mineralization at
the site, and to establish proven and probable reserves. The Company believes
that the proximity of the Cobrizos property to the San Cristobal Project may
result in significant operating efficiencies. Open pit mining with processing
either at the deposit site or at the proposed milling and processing facility
at the San Cristobal Project will be evaluated, and metallurgical test work
will be conducted.
 
EL OCOTE
 
 Location and Access
 
  The El Ocote property in southwestern Honduras is located near the town of
Santa Lucia in the municipality of La Labor, department of Ocotepeque,
approximately 150 kilometers south of the major city of San Pedro Sula and
approximately 30 kilometers east of the Guatemalan border. The property is
accessible by means of the paved Pan-American Highway which passes within one
kilometer of the deposit. Power, water and labor are available within two
kilometers of the property. The site is largely unimproved with no equipment
on site; some underground development has occurred, and it is possible to
inspect the mineral body from four adits.
 
 Operating History
 
  A portion of the El Ocote property was first explored and put into
production in the late nineteenth century. Rosario Resources ("Rosario"), a
New York-based company, subsequently acquired the property and in 1963 drilled
four diamond drill holes. According to Rosario's geologists responsible for
the project, Rosario decided against further development due to difficult
logistics and what was perceived to be unfavorable metallurgy. Rosario's
metallurgical studies at the time indicated that the mineralized material at
the site was best processed by flotation.
 
 Title and Ownership Rights
 
  In 1983, a Honduran entity, Compania Minera Ocote, S. de R.L. ("Minera
Ocote") acquired the property. In June of 1994, the Company, acting through an
agent, acquired an exclusive five-year exploitation concession and purchase
option for the El Ocote property from Minera Ocote totaling 986 acres. Minera
Ocote's rights to the property derive from a 40-year mining concession granted
by the government of Honduras in March of 1983, which may be extended for an
additional 20-year term.
 
                                      41
<PAGE>
 
  Pursuant to the contract with Minera Ocote, the Company has committed to
undertake a five-year, $1,000,000 exploration and development program on the
property, and to advance production royalties of $50,000 and $75,000 to Minera
Ocote on the fourth and fifth anniversaries, respectively, of the agreement.
The Company is also responsible for maintaining Minera Ocote's concession
until such time as title has been formally transferred to the Company. Minera
Ocote has agreed to transfer the title to the property on the fifth
anniversary of the aforementioned contract, assuming the property is in
production, or at such earlier time as the Company may request. Upon the
commencement of commercial production at the property, the Company will pay
Minera Ocote a five percent NSR royalty.
   
  In addition to the aforementioned concession at the El Ocote property, the
Company has also contracted with Minera Ocote to acquire an exploration
permit, the Ocote Exploration Zone, covering approximately 17,414 acres of
adjacent territory. Minera Ocote's title to this exploration permit was
formally granted in March of 1996. This exploration permit will have a life of
four years, extendable for an additional two years before converting into an
exploitation concession. The Company expects that if it elects to acquire this
permit outright from Minera Ocote, title to the property will be assigned to
Cordilleras Honduras. The Company also holds a right of first refusal with
respect to another property contiguous to the El Ocote property.     
 
 Geology
 
  The major geological feature of the El Ocote property is a zone of
mineralized breccia rock contained in a near vertical pipe-shaped structure.
This pipe is located at an altitude of approximately 1,600 meters on the side
of the very steep eastern slopes of Cordillera Del Merendo. The deposit is
hosted by a thin package of Tertiary andesitic volcanics, which overlie
Tertiary sediments and volcaniclastics, as well as Cretaceous Yojoa Group
limestones. Although faults are believed to be present immediately east and
northeast of the structure, it does not appear to have been subjected to any
significant post-mineral faulting.
 
  The deposit consists of a near vertical column of brecciated diorite,
roughly oval in plan section, in which silver and copper minerals, plus
fluorite, and quartz form the cement around the breccia fragments. This
structure in plan has dimensions of 150 meters (north-south) by 90 meters
(east-west). Within the mineralized structure, the fragments comprise angular
to rounded diorite and diorite porphyry. The degree of brecciation decreases
with depth, such that at a depth of less than approximately 50 meters below
the 1,200 level, there is no longer significant brecciation and the rock is
merely weakly jointed.
 
  The bulk of the silver mineralization is in one massive block of breccia
near the surface, with the grade diminishing rapidly below the 1,200 meter
level. Below that level, most of the higher grade material takes the form of
several arcuate bands, concave upward, which extend downward from the west
side of the structure and which terminate with depth toward the east.
 
 Mineralized Material
 
  In 1995, the Company began a process of evaluating the exploration and
development potential of the identified mineralized zone at the El Ocote
property. Specifically, the Company resampled four preexisting mine levels,
mapped the geology of the area, prepared topographic maps of the site, and
drilled 16 RC drill holes into the pipe-like structure and two RC holes into
the surrounding host rock. A total of 3,422 meters of drilling was completed
during this program and a total of 2,258 samples from these holes were sent
for assay. Using this drill assay data and the data from 313 samples from the
underground mine workings, the Company estimated that the deposit contains
approximately 2.1 million tonnes of mineralized material containing 9.9 ounces
of silver per tonne at a cut-off grade of 2.0 ounces of silver per tonne.
 
 
                                      42
<PAGE>
 
 Conceptual Study
 
  The Company commissioned Davy to prepare a conceptual study in order to
estimate the potential and timing of undertaking rapid exploitation of the
property via rapid bulk underground mining and heap leach extraction methods.
This study utilized the Company's estimate of mineralized material mentioned
above.
 
  This study was completed in July of 1997 and concluded as follows:
 
  . The project's economics are sensitive to metallurgical recovery and metal
    prices. Assuming a 50 percent heap leach recovery, the project's internal
    rate of return is positive with silver prices of approximately $6.00 per
    ounce, or at a 75 percent recovery, a positive rate of return begins at
    prices above $4.00 per ounce of silver.
 
  . Metallurgical test work should be undertaken to determine cyanide
    consumption and silver recovery rates.
 
  . Upside potential lies in lower cyanide consumption rates and the
    discovery of ore reserves to improve the return on capital invested in
    the mining and processing facilities.
 
 Exploration and Development
 
  The Company plans to commission an extensive metallurgical sampling and
testing program as the next step in its continuing evaluation of this
property. The Company believes that there is little likelihood of discovering
additional resources within the pipe structure itself. Nonetheless, as part of
the appraisal of the mineral potential of the El Ocote property, a regional
stream sediment survey was conducted over an area of 80 square kilometers. The
stream draining the mineralized area at the El Ocote property assayed 0.6
parts per million ("ppm") silver. Most other streams in the immediate area
assayed under 0.5 ppm silver. However, a large number of streams draining an
area 4.5 kilometers southwest of the mineralized structure assayed from 0.6 to
2.6 ppm silver. As numerous streams draining this area are strongly anomalous
in silver, the Company believes it is likely that additional silver
mineralization may occur in the headwaters of those sampled streams. The
Company plans to conduct further reconnaissance field work in this anomalous
area until the source of the silver is discovered.
 
SAN JUAN DE LUCANAS
 
 Location and Access
 
  The San Juan de Lucanas property is located 147 kilometers east of the town
of Nazca in the San Juan district of the Lucanas province in the department of
Ayacucho in southern Peru, approximately 500 kilometers south of Lima. The
property is accessible by means of a partly-paved, well-maintained highway
from Nazca which extends to within ten kilometers of the property and is
connected to the mine and mill site by well-established gravel roads. Water
and labor are available on site while power must be generated at the site.
 
 Operating History
 
  Mineralization was discovered in the San Juan district in colonial times.
Documented mining has occurred intermittently in the area since 1938. Empresa
Minera San Juan de Lucanas S.A. ("EMSJ") operated the San Juan de Lucanas mine
from 1966 until 1990, at which time operations were discontinued due to
operating losses. Between 1990 and early 1996, a small mining cooperative
 
                                      43
<PAGE>
 
intermittently ran the San Juan de Lucanas mine at a low production level.
Since 1951, the three mined veins at San Juan de Lucanas property have
produced approximately 3,000,000 tonnes of ore grading an average of 13.8
ounces of silver per tonne and 0.061 ounces of gold per tonne. Mill recoveries
of 84 percent silver and 91 percent gold resulted in district production of
approximately 35,830,000 ounces of silver and 170,400 ounces of gold.
 
 Title and Ownership Rights
 
  Through its new claims and the acquisition of mining concessions and certain
contract rights entitling it to explore and develop mining concessions in the
district, the Company has acquired title to, or otherwise controls, mineral
rights to more than 52,000 acres of properties dispersed over an area of
approximately 150 square miles in the San Juan district of the Lucanas
province of Peru. The Company has contracted to acquire 38 existing mining
concessions relating to 42,071 acres of land, including the aforementioned
pre-existing mining complex, and has staked new claims covering more than
10,131 acres. The Company believes that it controls all known mineralized
structures in the San Juan district.
 
  The registered holders of title to the 38 mining concessions include EMSJ
and Banco Minero del Peru, S.A. ("Banco Minero"), a Peruvian state bank which
is in liquidation. Among EMSJ's creditors were Banco Minero, which became
EMSJ's sole shareholder, and EMSJ's former employees, who where the
beneficiaries of certain statutory labor liens on EMSJ's assets. As a result,
these mining assets, although primarily registered in the name of EMSJ, also
included certain properties registered in the name of Banco Minero which are
now registered in the name of ASC Peru, a subsidiary of the Company. In June
of 1993, Banco Minero agreed to transfer ownership of the San Juan de Lucanas
mining complex to EMSJ's former workers in exchange for a release of all
claims by such workers against EMSJ and its successor in interest, Banco
Minero. The Banco Minero settlement agreement was subject to (i) a two-step
court approval process and (ii) subsequent registration with the Peruvian
Registry of Mines. The approval process has been completed and the
registration of the settlement agreement has been ordered by the Labor Court
in Lima. The registration of the settlement agreement, transfer of title to
the Company and the raising to public deed of the Company's rights to acquire
the concessions, however, remain pending.
 
  The Company has contracted with more than 90 percent in interest of the
beneficiaries of the Banco Minero settlement agreement to acquire all of their
rights in the San Juan de Lucanas mining complex (such contracts, the "San
Juan Contracts"). The Company has obtained the opinion of local counsel
attesting to the validity and enforceability of the San Juan Contracts. In
order for the Company to perfect its title to the San Juan de Lucanas mining
complex, the Banco Minero settlement agreement must be duly registered with
the Peruvian Registry of Mines. Since Peruvian law does not provide for
fractional interests in mining properties as an administrative procedure, a
special purpose mining entity, to be named SMRL Dorita I de Ica ("SMRL"),
which will be beneficially owned by the workers party to the settlement
agreement, will become the holder of the title to the San Juan de Lucanas
property. The SMRL is broadly analogous to a Peruvian limited liability
corporation. Pursuant to the San Juan Contracts, the Company will become the
holder of at least 90 percent of the participating interests in SMRL. The
Company expects that pursuant to the San Juan Contracts, SMRL will be
compelled to sell the San Juan de Lucanas property to the Company or its
designee upon the registration of the settlement agreement.
 
  As several of the former workers party to the Banco Minero settlement either
are not party to the San Juan Contracts, or have sought or may be expected to
seek to opt out of the San Juan Contracts, the Company's interest in
particular properties comprising the San Juan de Lucanas mining complex may be
subject to a small amount of dilution. Management does not believe that any
such dilution will have a material adverse effect on its interests or
activities in the San Juan district. The Company is
 
                                      44
<PAGE>
 
pursuing the rapid resolution of all title disputes and is committed to an
amicable settlement with all parties involved.
 
  Concurrent with the resolution of outstanding administrative legal issues,
the Company has taken steps to maintain an orderly physical presence in the
San Juan district. Of the 337 surviving ex-workers, approximately 60 continue
to live at the mining camp while the others no longer live in the district.
Those at the camp are living at a subsistence level. The Company provides
periodic truckloads of food and other supplies and has provided some
assistance to the local school and sports teams. The Company has two
representatives at the camp who periodically report to management, and the
Company's engineering personnel have made numerous uneventful visits to the
camp. However, the situation is unstable and is likely to remain so until such
time as the Company is able to make purchase payments on the SMRL properties.
The Company expects to make such payments as soon as the registration of the
settlement agreements have been completed and the San Juan Contracts have been
raised to public deed.
 
 Geology
 
  The mineral deposits at the San Juan de Lucanas property are epithermal,
with mineralization occurring in a number of steeply dipping veins, running
along two well defined orientations. The north-south veins include the veins
known as Santa Rosa, Saramarca, Yanarumi, Ventanilla and Rosaura; the
northeast-southwest vein is known as Concepcion-Raquel. The outcrops of the
Ventanilla and Concepcion-Raquel structures can be followed on the surface for
over one kilometer. The rocks hosting the veins consist of lava flows and tuff
flows with conglomerate.
 
  There are several systems of veins on the property. The Concepcion-Raquel
vein forms the most important structure in the district and is comprised of
two sets of three parallel structures each. The width of the veins varies
between two and four meters, although in some sections of the mine, widths
over 20 meters can be found. The Santa Rosa vein and another associated vein,
Alfa Romeo, form the second most important vein system; with vein widths
varying from one to seven meters. The third most important vein system is the
Saramarca system which is comprised of a series of veins and mineralization
occurring in lenses.
 
  All three vein systems are mineralized with gold, chalcopyrite, sphalerite,
galena, argentite and ruby silvers. Successive processes of leaching and
oxidation led to the formation of an enriched zone which constitutes the most
readily mineable portion of the deposit. The main minerals at the surface are
oxides extending to a depth of approximately 100 meters. The oxides contain
significant grades of silver and gold in some areas. Below this level, an
enriched zone with a vertical interval of 200 to 250 meters is present in most
of the known veins.
 
 Mineralized Material
 
  Underground mineralized material is estimated at 139,000 tonnes with an
average silver grade of 9.27 ounces per tonne and gold grade of 0.086 ounces
per tonne.
 
  During January and February of 1995, the Company engaged independent
contractors to survey and drill, under the supervision of Company geologists,
the two tailings dumps using impact casing methods. Twenty holes were drilled,
and 149 samples obtained. Approximately 85 percent of the tailings area was
sampled, and there is no reason to believe that the remaining 15 percent would
yield significantly different results.
 
  Based on the work described above, the Company estimates that the two
tailings dumps contain at least 1.75 million tonnes of mineralized material
with an average silver grade of 1.74 ounces per tonne and gold grade of 0.006
ounces per tonne. The Company sent a 60 pound (30 kilogram) sample to the
University of Cardiff, Wales, for metallurgical testing to estimate
recoveries, material balances
 
                                      45
<PAGE>
 
for various throughputs for processing the tailings, reagent consumption and
preliminary equipment and capital specifications. PAH found that these test
results support the concept of reprocessing the tailings profitably, assuming
a tailings reclaim agglomerate and heap leach process for a new or refurbished
underground mine combined operation. The tailings component would contribute a
net cash margin (before tax) of $1.99 per ounce of silver at an assumed price
of $5.15 per ounce of silver.
 
 Conceptual Study
 
  In June of 1995, PAH performed a conceptual study evaluating the
rehabilitation of the idled San Juan de Lucanas mine complex. PAH concluded
that rehabilitation would be feasible, and require approximately $10 million
to return the mine to a 500 tpd underground mining operation. Operating cash
costs of a rehabilitated and developed mine were estimated by PAH to be
approximately $2.40 per ounce of silver when fully operational. PAH outlined a
mine and power rehabilitation program and also defined requirements for
replacement of the crushing and grinding sections, a new flotation plant,
thickening section and cyanidation section, and repairs to the Merrill-Crowe
precipitation section. All ancillary structures would have to be rebuilt. The
Company believes additional reserves, which could result from such proposed
exploration, would be required to justify such investment.
 
 Exploration and Development
 
  The Company has defined a two stage, 5,500 meter core drilling program with
the goal of delineating an additional two million tonnes of reserves within
the known vein system. The first stage would consist of 12 core holes drilled
into eight veins to depths averaging 250 meters, for a total of 2,875 meters.
The second stage would consist of another 10 holes in the same veins, for a
total of 2,625 meters. If successful, a third phase consisting of additional
drilling and underground drifting will be conducted, the results of which will
be used to justify the rehabilitation and development of the mine, as well as
further exploration on other parts of the property.
 
CHOROMA
 
 Location and Access
 
  The Choroma property is located in the Bolivian silver-tin belt, 600
kilometers south of La Paz and 80 kilometers north of the border with
Argentina. It is 15 kilometers northeast of the small regional commercial
center of Tupiza, which is served by the railroad connecting Salta, Argentina
with Antofagasta, Chile and La Paz. Elevations in the prospect area range from
3,100 to 3,500 meters above mean sea level.
 
 Title and Ownership Rights
 
  The property is covered by approximately 310 acres of mining rights owned by
Comibol. The right to joint venture with Comibol was acquired through public
tender and contracted in July of 1996. The terms of the 40-year renewable
agreement provide for an initial five-year exploration period during which the
Company must make the following payments and investments in the property in
order to maintain the joint venture:

  Comibol will receive five percent of the operating cash flow, as defined
below, from production at the Choroma property until the Company has recovered
its entire capital investment; thereafter, Comibol will receive 15 percent of
operating cash flow. The Company has the right, in its discretion, to reduce
the acreage subject to the joint venture agreement prior to commencement of
the third year thereof and again prior to the commencement of the fifth year
thereof. Operating cash flow is defined in the agreement as the gross revenues
less the cost of transportation, smelting and refining, marketing commissions,
production costs and administrative expenses. Financing costs and depreciation
are not deductible from gross revenues.
 
 Operating History
 
  Production records are not available for the Choroma property. Pods of high-
grade lead-silver oxide ores were mined from veins during the Spanish Colonial
era. During the first half of the twentieth century, the deposit belonged to
Simon I. Patino until it was nationalized in 1952, when the property became
part of Comibol. Comibol leased the property to Messrs. H. Berinduague and A.
Levy, and finally to a miners' cooperative. Between 1976 and 1985, Comibol
rehabilitated several mine workings, carried out 526 meters of development on
several veins, and drilled 3,336 meters of core in 15 holes. The results of
this work are not in the Company's possession and reportedly have been lost by
Comibol. The mine was inactive when the United Nations Development Program
(UNDP) issued its report in December of 1990, following a 15-day field study.
UNDP concluded that the deposit had potential for the discovery of bulk
mineable material in fractured or brecciated rock as well as for traditional
vein ore bodies.
 
  During the first quarter of 1996, geologists for the Company channel sampled
many of the outcrops at the Choroma property. This work defined several lines
44 to 86 meters long which each averaged between 1.8 ounces of silver per
tonne and 4.0 ounces of silver per tonne. The Company acquired the property on
the basis of this work and the earlier reports.
 
 Geology
 
  The deposit is located near the southern end of the Bolivian silver-tin belt
in a sequence of dark colored shales of Ordovician age that have been intruded
by one or more porphyry domes of quartz dacitic to rhyolitic composition.
Veins and associated hydrothermal breccias occupy steep fractures trending
northwest. Hydrothermal alteration in rocks flanking the mineralized
structures consists of locally intense silification overprinted on more
broadly distributed propyllitic dominated by chlorite. Vein filling consists
of quartz, siderite, pyrite, chalcopyrite, arsenopyrite, galena, sphalerite,
tetrahedrite, tenantite and argentite with local concentrations of canfieldite
and agyrodite. Gold grades of up to 0.064 ounces per tonne are present in at
least one vein.
 
 Exploration
 
  Sampling of outcrops has defined several anomalies, which the Company
intends to drill in order to test for bulk mineable mineralization. In
addition, access will be gained to underground workings for sampling of
structures and wallrocks to further test for bulk mineable mineralization as
well as ore hosted by veins.

                           OTHER MINERAL PROPERTIES
 
  In addition to the aforementioned development project and advanced
exploration properties, the Company has a portfolio of more than two million
acres of exploration properties located in the traditional silver producing
regions of the world or otherwise identified by the Company as areas which
warrant exploration. The Company generally seeks to structure its acquisitions
of mineral properties in order to allow the Company to engage in phased
exploration of individual properties at a relatively low cost and to acquire
those properties that it regards as presenting significant development
opportunities. Properties which the Company determines do not warrant further
exploration or development will be sold or otherwise relinquished, typically
without further cost obligations to the Company. The Company currently holds,
controls or has options to acquire 22 major groups of exploration properties
located in eight countries. The distribution of these holdings is summarized
in the table below.

(/1/) Acreage and percent of total acreage figures do not include land
      considered part of the San Cristobal Project, El Ocote, San Juan de
      Lucanas, Cobrizos and Choroma properties. These five properties consist
      of claims and concessions comprising approximately 6,518 acres, 988
      acres, 52,200 acres, 4,178 acres and 309 acres, respectively.
 
  While the Company in the near term expects to focus primarily on the
development of the San Cristobal Project, the acquisition, exploration and
evaluation of properties will be vigorously pursued in order to unlock the
potential value of the Company's existing exploration property portfolio as
well as to sustain continuing corporate growth objectives.
 
  Drilling and geophysical engineering services are frequently subcontracted
to regional and/or international firms. Chemical analysis generally is
performed in laboratories located in the same regions as the specific
property, with metallurgical testing and analysis conducted in the U.S. When
using core drilling, the Company uses conventional split core sampling in its
testing, retaining one half of all drill cores for reference and confirmatory
testing processes. Similarly, representative portions of chip samples from
rotary percussion, reverse circulation drilling are processed leaving
substantial quantities of the chip sample material for reexamination and other
future test work.
 
  The Company's international exploration activities are described on a
country-by-country basis below. Due to the limited nature of the available
information regarding these properties, the general exploration portfolio is
addressed below in a summary manner only.

BOLIVIA
 
  The Company has continued its aggressive land acquisition program throughout
Bolivia, making the Company one of this country's largest private owners of
mineral rights. The Company's holdings and joint ventures, excluding the
Cobrizos property, the Choroma property and the San Cristobal Project, now
total almost 950,000 acres, including its existing joint venture interests for
the historic Pulacayo mine and options on several properties being explored
presently. The Company expects to pursue aggressively its exploration program
in Bolivia.
 
CHILE
 
  The Company has been systematically staking concessions in northern Chile.
This program, which is based on efforts to identify promising silver
exploration zones, has resulted in the staking of 22 claims over an area of
more than 53,000 acres. The Company's exploration of its Chilean property
holdings are at an early stage.
 
PERU
 
  In addition to its San Juan de Lucanas property, the Company has undertaken
numerous activities in Peru, including: (i) the acquisition and preliminary
evaluation of the Otuzco property located in northern Peru which has been
leased and is subject to a purchase option held by the Company; and (ii)
technical evaluation of a number of the mining properties being sold by
Centromin, the Peruvian state-owned mining company. The Company is presently
engaged in land acquisition programs in several districts.
 
MEXICO
   
  Exploratory work in Mexico has successfully secured a significant land
position in the vicinity of Zacatecas, historically Mexico's largest silver
producing district. An initial exploration program was completed in March of
1997. The Company's continuing program is evaluating the potential for several
underground silver operations. Additional exploration targets throughout
Mexico are being analyzed by the Company's Zacatecas office.     
 
HONDURAS
 
  In addition to its El Ocote property, the Company has acquired an extensive
land position in Honduras, encompassing more than 396,000 acres of exploration
and exploitation concessions. The Company's analysis of these properties
remains preliminary. Over the course of the next 12 to 18 months, the Company
expects to conduct additional field reconnaissance in order to determine
further drill targets at these properties.
 
KYRGHYZSTAN
 
  On March 26, 1996, the Company established Kumushtak Mining, a 50/50 joint
venture with North-Kyrghyz Geological Expedition, a state enterprise organized
under the laws of the Kyrghyz Republic. Kumushtak Mining holds concessions
located in a belt of silver occurrences which extends for several hundred
kilometers in the Kumushtak river valley in western Kyrghyzstan. The area
encompasses several historic mining districts.
 
  The Company recently completed its first round of drilling at one
significant silver anomaly situated in Kumushtak. The results of such drilling
indicate insufficient grades to sustain economic production at prevailing
silver prices. However, due to Kumushtak Mining's large property holdings and
exploration potential, the Company intends to preserve a strategic position in
this region and continue with its interest in Kumushtak Mining. The Company
believes that Kumushtak Mining's extraordinarily large concession offers the
possibility of numerous occurrences of silver and gold.

MONGOLIA
 
  On March 26, 1996, the Company established Asgat Mining, a 50/50 joint
venture with Mongolrostvetmet, a joint association owned by the Mongolian
government and Zarubeshvetmet, a privatized company formed under the laws of
the Russian Federation. Asgat Mining is involved in the evaluation of the
Asgat silver deposits in northwestern Mongolia (the "Asgat Silver Property").
 
  Work on the Asgat Silver Property, which already contains some underground
development, has principally involved data preparation for a feasibility
study. Recently, metallurgical bench scale test work has been conducted with
mixed results. While recoveries of silver and copper were high, the results
indicated large amounts of arsenic and antimony. The Company regards the Asgat
Silver Property as a strategic property position with potential long term
development prospects. Asgat Mining is presently assessing other precious
metal prospects based on its detailed knowledge of information and conditions
in Mongolia.
 
TAJIKISTAN
 
  The Company is in the process of obtaining an exclusive, irrevocable license
to exploit the Bolshoi Kanimansur and the Western Kanimansur silver deposits
in northern Tajikistan, through the formation of Kanimansur Mining, which will
be 49 percent owned by Apex Asia and 51 percent by Adrasman Mining. The
Company is considering entering into a joint venture with respect to the
property with Zarabeshtsvetmet, a Russian mining company.

                            METALS MARKET OVERVIEW
 
SILVER MARKET
 
  Silver has traditionally served as a medium of exchange, much like gold.
While silver continues to be used for currency, the principal uses of silver
can be divided into three main categories: (i) industrial uses, primarily
electrical and electronic components; (ii) photography; and (iii) jewelry and
silverware. According to the Silver Institute, in 1996, approximately 720
million ounces of silver were consumed for these and other industrial
purposes.
 
  Silver's strength, malleability, ductility, thermal and electrical
conductivity, sensitivity to light and ability to endure extreme changes in
temperature combine to make silver a widely-used industrial metal.
Specifically, it is used in batteries, computer chips, electrical contacts,
and high-technology printing. Silver's anti-bacterial properties also make it
valuable for use in medicine and in water purification.
 
  Most silver production is obtained from mining operations for which silver
is not the principal or primary product. Approximately 83 percent of mined
silver is produced as a by-product of mining of lead, zinc, gold or copper
deposits. According to the Silver Institute, approximately 400 million ounces
of silver were mined in 1996. CPM estimates that recycled or secondary
production accounts for a decreasing proportion of total silver supply,
approximately 29 percent of total silver production in 1996, compared to an
average of 36 percent of aggregate silver production between 1980 and 1990.
CPM further estimates that total silver supply (from mine production,
recycling and estimated dishoarding and government stockpile sales) has been
insufficient to meet industrial demand since 1989, and stockpiles have been
diminishing. CPM studies indicate that approximately 576 million ounces of
silver were supplied from all sources in 1996.
 
  The following table sets forth the London Silver Market's annual average
(except for 1997), high and low spot price of silver in U.S. dollars per troy
ounce since 1977.

ZINC AND LEAD MARKETS
 
  The Company anticipates that the San Cristobal Project will, and that other
future projects may, involve the production of economically significant
quantities of metals other than silver. The Company expects that production
from the San Cristobal Project will include the extraction, processing and
sale of significant quantities of zinc and lead.
 
  Zinc is utilized for its resistance to corrosion, and, in the form of steel
coating, is widely used in construction of infrastructure, housing and office
buildings. In the automotive industry, zinc is used for steel coating, and die
casting, and is an important component of tires and motor oil. Smaller
quantities of various forms of zinc are used in fertilizers, food supplements
and cosmetics, and in specialty electronic applications such as satellite
receivers. Industrial consumption of zinc in 1996 was estimated by the
International Lead Zinc Study Group (the "ILZSG") at 6.28 million tonnes.
Recycled zinc accounts for about 30 percent of the zinc consumed on an annual
basis. According to the ILZSG, 5.94 million tonnes of zinc were produced in
1996.
 
  The primary use of lead is in motor vehicle batteries, but it is also used
in cable sheathing, shot for ammunition and alloying, and in chemical form for
use in alloys, glass and plastics. Industrial consumption of lead in 1996 is
estimated by the ILZSG at 5.08 million tonnes. Lead is widely recycled with
secondary production accounting for a steady 54 percent of total supply.
According to the ILZSG, 5 million tonnes of lead were produced in 1996.
 
  The following table sets forth the annual average (except for 1997) spot
prices for zinc and lead on the London Metals Exchange since 1977.

                              REPUBLIC OF BOLIVIA
 
  The following information has been compiled by the Company from governmental
and private publications.
 
GENERAL INFORMATION
 
  Bolivia is situated in central South America and is bordered by Peru,
Brazil, Paraguay, Argentina and Chile. It has an area of 1,098,581 square
kilometers and a population of approximately 7.7 million people. Bolivia's
official and most widely spoken language is Spanish, but over 70 percent of
the population is either native Aymara or Quechua Indian. Sucre is the capital
city of Bolivia. La Paz is the seat of government and, with a population of
over one million people, the largest city in Bolivia. La Paz is situated on
the Altiplano, the high plateau which separates the eastern and western ranges
of the Andes. The land in this part of the country is largely semi-desert
plains bordered by steep, rugged mountains. The eastern portion of the country
consists of sparsely populated low-lands bordering the Brazilian Amazon basin
where temperate and tropical forest dominate. Santa Cruz is the principal city
of the low country with a population of approximately 700,000.
 
  The government of Bolivia consists of a directly elected president and a
bicameral congress. Since the military government stepped down in 1982,
Bolivia has maintained a stable democratic system with elections every four
years. The current president, Hugo Banzer, was elected by the Congress on
August 5, 1997, after no presidential candidate succeeded in winning a
majority of the votes in the general election held in June of 1997.
 
ECONOMY
 
  The Bolivian economy has experienced continuous growth and relatively low,
stable inflation in recent years. This economic performance is generally
ascribed to the deregulation of key sectors of the economy, including oil and
gas, communications, transport and finance, and to foreign direct investment
which has occurred as part of the recent privatization of formerly government-
owned electricity, telecommunications, railways, aviation and oil and gas
companies. The country's privatization program has involved (i) the sale of
shares in government-owned entities in exchange for capital contributions to
the privatized entities, and (ii) the contribution of government-owned shares
in such privatized entities to trust funds established on behalf of all
Bolivians over the age of 21 at the end of 1995. In connection with this
program, the Company has entered into joint venture agreements with the
government mining company, Comibol, with respect to two properties. Summary
information on the Bolivian economy is set forth in the table below.

  The official monetary unit of Bolivia is the boliviano, which was introduced
in January of 1987 following the adoption in 1985 of a broad based reform
program known as the "New Economic Policy". In the mid-1980s, prior to the New
Economic Policy, Bolivia suffered from hyperinflation, declining foreign
investment, growing balance of payments deficits and a foreign exchange
shortage fueled in part by an increasing disparity between the official and
unofficial exchange rates. The New Economic Policy removed restrictions on
exports and imports, ended most price controls and subsidies, instituted a
freeze on public sector wages and subjected the public sector to rigorous cost
cutting. By 1986, inflation was under control and the International Monetary
Fund resumed stand-by assistance. During the period of the New Economic
Policy, the gap between the official exchange rate and the parallel unofficial
rate was bridged. On December 31, 1996, the exchange rate was 5.19 bolivianos
to one U.S. dollar compared to the exchange rate on December 31, 1995 of 4.94
bolivianos to one U.S. dollar. On June 30, 1997, the exchange rate was 5.23
bolivianos to one U.S. dollar; over the past year the boliviano has shown a
tendency to depreciate approximately US$0.01 every 15 days.
 
  The boliviano is freely convertible in Bolivia at a single, public exchange
rate established by twice-weekly auctions held by the Bolivian Central Bank.
 
FOREIGN INVESTMENT AND TAX
 
  Since the New Economic Policy, most restrictions on trade have been removed
or are in the process of being phased out. Currently, import levies stand at
ten percent for all items except capital goods, which are subject to a five
percent levy. In March of 1991, a new export code introduced further measures
to liberalize trade. In order to prevent transfer pricing and other tax
avoidance mechanisms, almost all foreign trade transactions require the filing
of an aviso de conformidad describing the terms of the underlying
transactions.
 
  The 1990 Investment Law provides for unrestricted repatriation of capital,
freedom to import goods and services, equality under the law between foreign
and domestic companies, and the creation of "free trade zones".
 
  Mining companies in Bolivia are subject to a 25 percent income tax. Taxable
income is determined in accordance with Bolivian generally accepted accounting
principles. However, earnings reinvested (for specified purposes) in Bolivia
are deductible in computing taxable profits. If the reinvested capital exceeds
retained profits, the excess may not be carried forward. Income from the
export of derivative products from precious metals which include Bolivian
added value is exempt from taxes under the Bolivian Mining Code.
 
  Under the new Bolivian Mining Code, which came into effect on March 17,
1997, there is Complementary Mining Tax applicable to whomever carries out
mining activities, which would be payable if greater than the Bolivian income
tax. Mining activities are defined to include: prospecting and exploration;
mining or extracting minerals or metals; concentrating mine products; smelting
and refining; marketing of minerals and metals. The Complementary Mining Tax
is calculated by applying an aliquot to the taxable base. The aliquot of the
Complementary Mining Tax is a variable percentage (which fluctuates between
three percent and seven percent for precious stones and metals and between one
percent and five percent for other metallic minerals) indexed to the official
U.S. dollar market price for the relevant metal or mineral. The taxable base
is construed as the amount that results from multiplying the weight of the
fine content of the mineral or metal by its official U.S. dollar market price.
This tax is creditable against corporate income and is, in effect, a minimum
tax on mining companies. Manufacturing or processing involving minerals is not
subject to the Complementary Mining Tax.
 
  Bolivian source income, including dividends, interest, management fees and
expenses charged to a Bolivian company by foreign affiliates is subject to a
withholding tax of 12.5 percent.
 
                                      54
<PAGE>
 
  Operating losses (as adjusted for inflation) may be carried forward and
deducted from taxable income indefinitely. However, if accrued losses exceed
50 percent of capital (including that of a branch) the capital must be
increased.
 
  Bolivia assesses a 12.5 percent tax on profits of a branch of a foreign
corporation operating in Bolivia. The branch tax is calculated on the book
profits of the branch regardless of remittances or reinvestment of profits in
the branch. Book profits are deemed remitted 120 days after the end of the
fiscal year.
 
  There is a 13 percent value added tax ("VAT") on all sales, including
mineral commodities, a five percent import duty on machinery and equipment and
a ten percent duty on imported raw materials and components. The VAT paid on
purchases is recoverable against VAT collected on Bolivian sales. Exports are
not subject to VAT. The exporter can offset the VAT credit arising from
purchases with domestic sales or can apply for a refund of import duties and
VAT paid on inputs and raw materials included in the cost of exported goods.
However, the refund of credits arising from imports is limited to 13 percent
of the total value of the exports and therefore is not recoverable during the
exploration phase.
 
MINING INDUSTRY
 
  Bolivia produces a number of mineral commodities including tin, gold,
silver, lead, zinc, antimony, tungsten, copper and bismuth. The country has
long been a leading mineral and precious metals producer. Bolivia was
colonized in the early sixteenth century by Spaniards who arrived in search of
silver and gold. The extensive silver mining operations in Potosi which
developed under Spanish rule led to the region being described as the
"treasury of the Spanish empire". In the early Twentieth Century, tin became
the country's leading mineral export although in recent years the focus has
returned to gold, silver, lead and zinc. The country's principal mining
regions are the eastern part of Bolivia along the Brazilian border, and the
traditional mining areas of the Altiplano and Cordillera.
 
  Recent regulatory reforms have resulted in increased exploration activities,
particularly with respect to precious metals. In the early 1990s, the
government reformed the land tenure system, reduced taxes on mining
operations, established equal treatment under the law between Comibol and
foreign companies in obtaining mineral concessions, and created a national
Mining Inventory Service which will maintain up-to-date information, including
maps, for exploration and mining exploration concessions.
 
MINING CONCESSIONS
 
  Pursuant to the Bolivian constitution, all mineral deposits are the property
of the State. Mining concessions, which may be awarded by the government,
grant the holder, subject to the payment of patents, the real and exclusive
right to carry out prospecting, exploration, exploitation, concentration,
smelting, refining and marketing activities with respect to all mineral
substances located within a given concession. Individual mineral claims
consist of indivisible squares shaped like an inverted pyramid, whose lower
vertex is the center of the earth and whose surface area covers a total area
of 25 hectares. Mining concessions are comprised of no fewer than one and no
more than 2,500 adjacent squares. Mining concessions are distinct from the
surface rights which comprise traditional land ownership; holders of mining
concessions are entitled to explore and exploit a property and to use the
water found at the property. Expropriation or the establishment of easements
may not be legally carried out if the water supplies for a population are
interrupted or negatively affected.
 
  Holders of mining concessions are obliged to pay an annual mining patent.
Co-owners are jointly and severally responsible for the patent payment. The
patent is progressive and fees are based on the number of years of existence
of the concession. Concessions established before the enactment of the new
Mining Code, which comprise an area of up to 1,000 mining claims, pay the
equivalent of
 
                                      55
<PAGE>
 
$1.00 per claim per year. Concessions established before the enactment of the
new Mining Code which comprise an area of more than 6,000 mining claims pay
the equivalent of $1.00 per claim per year for the first five years of the
existence of the concession; thereafter, the patent increases to the
equivalent of $2.00 per claim per year. Concessions established under the new
Mining Code pay the following: for the first five years of the existence of a
concession, the owner is required to pay the equivalent of $25.00 per square
per year; thereafter the patent increases to the equivalent of $50.00 per
square per year. All of the Company's Bolivian concessions were established
prior to enactment of the new Mining Code.
 
  Mining concessions are liable to forfeiture when the corresponding annual
patent fails to be paid. Forfeiture is governed by law and does not require
any administrative or judicial declaration. When a concession has been
forfeited, the mining concession reverts to the State.
 
  The Mining Code requires concession holders to minimize damage to surface
rights, to neighboring concessions and to the environment. Concession holders
are liable for damage or injury caused by their operations. Concession holders
are not obliged to remediate environmental damage caused prior to the
effectiveness of the Environmental Law or the date on which the mining
concession was obtained, if the concession was granted at a later date. On
becoming the owner of a concession, the concession holder must carry out an
environmental audit to determine the extent of any environmental damage. If an
environmental audit is not performed, the concession holder assumes the
responsibility to mitigate all environmental damage. Environmental liabilities
incurred under this new regime survive the existence or ownership of the
relevant concession.
 
  In 1992, the Bolivian government passed environmental legislation that
establishes a comprehensive scheme for the initiation of a national
environmental policy to protect the environment, promote sustainable
development, promote the preservation of biological diversity and promote
environmental education. Few environmental regulations specifically applicable
to mineral exploration companies in Bolivia have been proclaimed to date. At
present, concession holders must maintain waterways running through their
concessions in their unspoiled state and concession holders must employ
exploration and development techniques that will minimize environmental
damage. Under Bolivia's environmental regulations, environmental impact
assessments are required. In practice, foreign mining companies operating in
Bolivia generally adhere to U.S. and European environmental standards for
mining and exploration.
 
LABOR MARKET
 
  Bolivia has a large pool of unskilled and, in the mining sector, semi-
skilled labor, but a relative shortage of skilled labor and managerial
expertise overall. One percent of the payroll tax is used for worker training.
A large portion of the labor force that is engaged in wage employment is also
unionized, although union participation is not mandatory. Strikes, which have
decreased greatly since the early 1980s, are not forbidden. However, before a
strike may be called, all legally-mandated alternatives, such as negotiation,
mediation and conciliation, must have been exhausted. Collective agreements
are very rare, as negotiations are generally carried out between an individual
company's union and management.

accountants, reviewing with the independent accountants the plans and results
of the auditing engagement, and considering the independence of the Company's
accountants. Messrs. Comninos, Katz and Hoegh currently serve on the Audit
Committee.
 
  A Compensation Committee has also been established to review the Company's
compensation policies and supervise the Company's Share Option Plans. See

of the total number of directors constituting the entire board and
approximately one-third of the members of the board are elected at each annual
meeting of stockholders. The Class I directors are Messrs. Conger, Katz and
Comninos; the Class II directors are Messrs. Hulley, Soros and Hoegh; and the
Class III directors are Messrs. Kaplan, Elsztain and Hanna. The term of the
Class I directors will end on the date of the 1998 annual meeting of
stockholders. The term of the Class II directors will end on the date of the
1999 annual meeting of stockholders. The term of the Class III directors will
end on the date of the 2000 annual meeting of stockholders. If the number of
directors is changed, any increase or decrease in the number of directors will
be apportioned among the classes so as to maintain the number of directors in
each class as nearly equal as possible, and any additional directors of any
class elected to fill a vacancy resulting from an increase in such class will
hold office for a term that coincides with the remaining term of that class.
Each director will hold office until the annual meeting for the year in which
his term expires and until his successor shall be elected, subject, however,
to his prior death, resignation, retirement or removal from office. Any
vacancy occurring in the board for any reason will be filled by a vote of the
majority of the directors then in office, even if less than a quorum, or by a
sole remaining director. Any director elected to fill a vacancy will hold
office for a term that coincides with the term of the class to which such
director was elected.

SHARE OPTION PLANS
 
  The Company has established two Share option plans; one for officers,
employees, consultants and agents of the Company and its subsidiaries, the
other for non-employee directors of the Company.
 
 Employee Share Option Plan
 
  The Company has established a share option plan for officers, employees,
consultants and agents of the Company and its subsidiaries (the "Employee
Share Option Plan"). The Employee Share Option Plan provides for the grant of
Ordinary Share options (including incentive Ordinary Share options as defined
in Section 422 of the U.S. Internal Revenue Code of 1986, as amended, (the
"Code")), Ordinary Share appreciation rights and other Share awards (including
restricted Ordinary Share awards, contingent Ordinary Share awards and
dividend or equivalent Ordinary Share awards) (collectively "Awards"). The
total number of options outstanding at any time cannot exceed ten percent of
the number of Ordinary Shares outstanding from time to time. Options granted
under the Employee Share Option Plan are non-assignable and exist for a term,
not to exceed ten years, fixed by the Compensation Committee of the board of
directors of the Company (the "Committee"). The exercise price of options
granted on or before the date of the Offering is $8.00 per share. The exercise
price of options granted after the date of the Offering is determined by the
Committee at the time the option is granted; provided that the exercise price
shall not be less than 100 percent of the fair market value of the share on
the date of the grant. In the case of an incentive share option granted to an
employee owning (actually or constructively under Section 422(d) of the Code),
more than ten percent of the total combined voting power of all classes of
Ordinary Shares of the Company, the price of any such option shall not be less
than 110 percent of the fair market value of the Ordinary Shares on the date
of grant. The aggregate fair market value (determined at the time the
incentive share options are granted) of the Ordinary Shares with respect to
which incentive share options are exercisable for the first time by any
optionee during any calendar year under all plans of the Company shall not
exceed $100,000. Awards may be granted by the Committee on such terms,
including vesting schedules, price, restriction
 
                                      67
<PAGE>
 
or option period, dividend rights, post-retirement and termination rights, and
payment forms as they deem appropriate. Unless terminated by the board of
directors, the Employee Share Option Plan continues until August 1, 2006.
 
  Options grants made under the Employee Share Option Plan provide that in the
event of a Change in Control (as defined in the Employee Share Option Plan),
the options whether or not currently vested and exercisable, shall become
immediately vested and exercisable as of the effective date of the Change of
Control.
 
  Under the Employee Share Option Plan, as of the date hereof, options to
purchase an aggregate of 415,000 Ordinary Shares are outstanding. All such
options are exercisable at a price of $8.00 per share. See "Principal
Shareholders".
 
 Non-Employee Director Share Option Plan
 
  The Company has established, a share option plan for non-employee directors
of the Company (the "Non-employee Director Share Option Plan"). The total
number of options outstanding at any time cannot exceed five percent of the
number of Ordinary Shares outstanding from time to time. Options granted under
the Non-employee Director Share Option Plan are non-assignable (except for
approved assignments to immediate family members) and expire at the earlier of
(i) ten years after the date of the grant of the option or (ii) one year after
the director ceases to be a director of the Company. Options shall have an
exercise price of 100 percent of the Fair Market Value (as defined in the Non-
employee Director Share Option Plan) of the Ordinary Shares on the date of the
grant. The Non-employee Director Share Option Plan provides for the automatic
grant of (i) an option to purchase the number of Ordinary Shares equal to
$50,000 divided by the Fair Market Value of the Ordinary Shares on the date of
the grant to each non-employee director at the effective date of their initial
election to the board of directors and, (ii) an option to purchase the number
of Ordinary Shares equal to $50,000 divided by the Fair Market Value of the
Ordinary Shares on the date of the grant at the close of business of each
annual meeting of the shareholders of the Company.
 
  No options have been granted under the Non-employee Director Share Option
Plan. However, non-employee directors have received options pursuant to
individual grants. See "Principal Shareholders".
 
OTHER PLANS
 
  In 1997, Apex Corporation instituted a 401(k) Plan for its U.S. employees.
Apex Corporation makes monthly contributions to this 401(k) Plan, and
currently matches 50 percent of each employee's contribution up to an employee
contribution of six percent of base salary. Employees vest in the company's
contribution at 50 percent after one year of service and 100 percent after two
years of service. Although the Company does not currently have a formal bonus
or incentive plan for any of its employees, it anticipates instituting a bonus
plan in the future.

                             CERTAIN TRANSACTIONS
   
  In December of 1994, Silver Holdings formed by (i) Quantum Industrial
Partners LDC, (ii) Geosor Corporation, (iii) VDM, Inc. (iv) entities
affiliated with Mr. Elsztain, and (v) Jack Nash, purchased a 75 percent
interest in Apex LDC in exchange for a $10 million demand note (the "Note")
payable to Apex LDC. Upon Silver Holdings' investment, Mr. Paul Soros and Mr.
Elsztain were appointed to Apex LDC's board of directors. As part of this
investment, and in consideration of introducing the principals of the Company
and Silver Holdings to each other. Litani Capital Management Ltd. ("Litani
Ltd."), an international business company formed under the laws of the
Bahamas, was granted an option to purchase 35 percent of the issued and
outstanding shares of Apex LDC from Silver Holdings for an amount equal to
Silver Holdings' initial purchase price for such shares, plus interest thereon
calculated at an annual rate of 20 percent.     
 
  In connection with the investment by Silver Holdings, Apex LDC agreed to pay
Tigris Financial Group Ltd. ("Tigris"), a corporation formed under the laws of
the State of Delaware, an annual advisory fee of $75,000, plus expenses, in
consideration for Mr. Kaplan's services to Apex LDC and its subsidiaries. Mr.
Kaplan is the sole shareholder of Tigris. This consulting arrangement was
terminated at the end of the first quarter of 1997, following the formation of
Apex Corporation. In addition, Apex LDC agreed to pay Litani Ltd. an annual
advisory fee of $45,000, plus expenses, in consideration for Litani Ltd.'s
services to Apex LDC and its subsidiaries. The right to this fee was
subsequently assigned to LCM Holdings LDC, a limited duration company formed
under the laws of the Bahamas ("LCM Holdings LDC"). This consulting
arrangement was terminated at the end of the first quarter of 1997.
   
  In the first half of 1995, Litani LDC succeeded to Litani Ltd.'s contract
rights with respect to Apex LDC, including the option, but excluding LCM
Holdings LDC's advisory fee. In July of 1995, Litani LDC completed the sale,
in a Private Placement, of 30 percent of its shares to accredited investors
(representing an approximately 10.5 percent beneficial economic interest in
Apex LDC) for approximately $6 million. In early August of 1995, Litani LDC
exercised its option to acquire from Silver Holdings 35 percent of the issued
and outstanding shares of Apex LDC for a price equal to approximately
$5,250,000. Substantially all of Litani LDC's assets consisted of its shares
of Apex LDC.     
 
  In January of 1996, the Company delivered to Silver Holdings a capital call
for the amount of the outstanding balance due on the Note. Silver Holdings
made its final payment under the Note, in the amount of just over $2.9
million, effective as of January 31, 1996.
 
  In the first four months of 1996, Apex LDC was restructured in order to
facilitate the 1996 Private Placement which was completed effective August 6,
1996. As part of this restructuring, Apex Limited was formed to serve as the
majority shareholder of Apex LDC. Apex LDC also formed ASM Holdings Limited
("ASM Holdings"), an exempted limited liability company organized and existing
under the laws of the Cayman Islands, and Apex Partners in order to facilitate
the purchase of minority interests in certain of Apex LDC's subsidiaries from
five officers of Apex Corporation. Apex Partners subsequently acquired a one
percent interest in each of Apex Asia, Cordillera Minera de Zacatecas,
Cordilleras Honduras, Andean and ASC Partners. The Company also purchased
certain minority profit interests in Honduran and Mexican properties from the
individual who had represented the Company in connection with the initial
acquisition of such properties.
   
  As part of the 1996 Private Placement, 4,256,700 shares of the Company were
sold at a price of US $8.00 per Ordinary Shares to accredited investors. The
gross proceeds from the 1996 Private Placement were $34,053,600. The Private
Placement agents for the sale included Salomon Brothers Inc and S.G. Warburg &
Co. Inc. In connection with the 1996 Private Placement, Consolidated
contributed its 25 percent interest in Apex LDC to the Company in exchange for
3,935,825 Ordinary Shares (approximately 30% of the Ordinary Shares
outstanding at such time, or 20%, assuming the issuance of the 7,077,007
Ordinary Shares reserved for issuance pursuant to the Buy-Sell Agreement),
    
                                      72
<PAGE>
 
   
and approximately 84 percent of the shareholders of Litani LDC exchanged their
interests in Apex LDC in exchange for 4,730,468 Ordinary Shares (approximately
36% of the Ordinary Shares outstanding at such time, or 23% assuming the
issuance of the 7,077,007 Ordinary Shares reserved for issuance pursuant to
the Buy-Sell Agreement).     
 
  Further in connection with the 1996 Private Placement, Apex LDC, the Company
and the other beneficial owners of Apex LDC entered into a Buy-Sell Agreement
dated as of August 6, 1996 (the Buy-Sell Agreement"). Pursuant to the terms of
the Buy-Sell Agreement, upon a request by a Minority Shareholder, the Company
is required to purchase, at its sole option, for cash, for Ordinary Shares or
for a combination of cash and Ordinary Shares, the shares of Apex LDC owned by
such shareholder. The Company currently expects that any future purchases by
Apex Limited of shares of Apex LDC from the Minority Shareholders will involve
only Ordinary Shares of Apex Limited. Any such transaction will not effect the
beneficial and economic interest in Apex LDC attributable to shareholders of
Apex Limited.
 
  Pursuant to a Shareholders' Agreement dated as of August 6, 1996 (the
"Shareholders' Agreement") by and among Apex LDC, the Company, the other
shareholders of Apex LDC, and each purchaser of Ordinary Shares in the 1996
Private Placement, such shareholders have agreed not to offer, sell, contract
to sell or otherwise dispose of, directly or indirectly, or announce the
offering of any Shares, including any such Shares beneficially or indirectly
owned or controlled by the Company, or any securities convertible into, or
exchangeable or exercisable for Shares, for 180 days from the date of this
Prospectus, without the prior written consent of Salomon.
   
  Dr. Larry J. Buchanan and Jon Gelvin, officers of the Company, are
shareholders and directors of Begeyge Minera Ltda. ("Begeyge"), from which the
Company purchased options for three properties in Honduras for a total of
$20,000. The Company declined to exercise its option to purchase two of the
three properties. From the time of entering into the option contracts until
December 31, 1996, the Company spent a total of $182,324 in connection with
the returned properties. During the period January 1, 1997 through June 30,
1997 the Company paid Begeyge $5,000 in lease payments for one of the returned
properties. The Company spent a further $9,619 in connection with this
property during the period. The Company still has an option to purchase the
remaining property for $3,000,000. Begeyge also serves as an associate of the
Company and during the period ended December 31, 1996, total expenditures
charged to the Company by Begeyge amounted to $106,691. During the period
January 1, 1997 through June 30, 1997, Begeyge did not receive any payment
from the Company other than the $5,000 in lease payments.     
   
  In 1996, Mr. Harry Conger, a director of the Company, received options to
purchase 25,000 Ordinary Shares at $8 per share. The option, were granted in
consideration of his consulting services for the Company and vest ratably over
four years, with the first tranche vesting on the date of grant.     
 
  In August 1997, the Company issued Mada Limited 25,000 shares in
consideration of its services to the Company.
 
  In August of 1997, the Company exchanged 268,496 Ordinary Shares for
Mintec's 2.5 percent interest in ASC Bolivia.
 
  In August of 1997, the Company issued Johnny Delgado Achaval, an officer of
the Company 113,595 Ordinary Shares of the Company in consideration of his
services to the Company.
 
  The Company is negotiating an agreement with Mintec in which the Company
would purchase from Mintec (i) its non-land assets for approximately $500,000
and (ii) concessions with respect to approximately 126,000 acres of land for
approximately $550,000. The closing of such transaction will not occur until
after the Offering.
   
  Silver Holdings, the Company, Mr. Kaplan, Argentum LLC, Aurum LLC, and

winding up, the full amount to which they shall be entitled, the holders of
the then outstanding Ordinary Shares shall be entitled to receive, pro rata
according to the number of Ordinary Shares registered in the names of such
shareholders, any remaining assets of the Company available for distribution
to its shareholders; provided, if, at such time, the holder of Ordinary Shares
has any outstanding debts, liabilities or engagements to or with the Company
(whether presently payable or not, either alone or jointly with any other
person, whether a shareholder or not (including, without limitation, any
liability associated with the unpaid purchase price of such Ordinary Shares),
the liquidator appointed to oversee the liquidation of the Company shall
deduct from the amount payable in respect of such Ordinary Shares the
aggregate amount of such debts, liabilities and engagements and apply such
amount to any of such holder's debts, liabilities or engagements to or with
the Company (whether presently payable or not). The liquidator may distribute,
in kind, to the holders of the Ordinary Shares remaining assets of the Company
or may sell, transfer or otherwise dispose of all or any part of such
remaining assets to any other corporation, trust or entity and receive payment
therefor in cash, shares or obligations of such other corporation, trust or
entity or any combination thereof, and may sell all or any part of the
consideration so received, and may distribute the consideration received or
any balance or proceeds thereof to holders of the Ordinary Shares.
 
  Voting Rights. The Articles provide that the quorum required for a general
meeting of the shareholders is not less than one shareholder present in person
or by proxy holding at least 50 percent of the issued and outstanding shares
entitled to vote at such meeting. Subject to applicable law and any provision
of the Articles requiring a greater majority, the Company may from time to
time by special resolution alter or amend the Memorandum or Articles;
voluntarily liquidate, dissolve or wind-up the affairs of the Company; reduce
its share capital or any capital, redemption or reserve funds, or any share
premium account; or change its name or alter its objects.
 
                                      75

  Each shareholder is entitled to one vote per share on all matters submitted
to a vote of shareholders at any such meeting. All matters, including the
election of directors, voted upon at any duly held shareholders' meeting shall
be carried by ordinary resolution, except (i) approval of a merger,
consolidation or amalgamation which requires (in addition to any regulatory or
court approvals) the approval of at least seventy-five percent of the
outstanding voting shares, voting together as a single class, (ii) any matter
that must be approved by special resolution, including any amendment of the
Memorandum and Articles, and (iii) as otherwise provided in the Articles. A
special resolution requires the approval of at least two-thirds of the votes
cast by holders of the outstanding voting shares voting together as a single
class represented in person or by proxy at a duly convened meeting. An
ordinary resolution requires the approval of a simple majority of votes cast
at a meeting of shareholders represented in person or by proxy.
 
  The Articles provide that, except as otherwise required by law and subject
to the rights of the holders of any class or series of shares issued by the
Company having a preference over the Ordinary Shares as to dividends or upon
liquidation to elect directors in specified circumstances, extraordinary
general meetings of the shareholders may be called only by (i) the directors
or (ii) at the request in writing of shareholders owning at least 25 percent
of the outstanding shares generally entitled to vote.
   
  The Ordinary Shares have noncumulative voting rights, which means that the
holders of a majority of the Ordinary Shares may elect all of the directors of
the Company and, in such event, the holders of the remaining Ordinary Shares
will not be able to elect any directors. The board of directors of the Company
is presently divided into three classes, of three directors each. At present,
each class is elected for a term of three years, with the result that
shareholders will not vote for the election of a majority of directors in any
single year. See "Management". Pursuant to the Articles, Directors may be
removed by the shareholders only with the vote of 80 percent of the
outstanding shares generally entitled to vote. The classified board provision
and the removal of directors by shareholder provision can only be amended with
the vote of 80 percent of the outstanding shares generally entitled to vote.
    
  This classified board provision could prevent a party who acquires control
of a majority of the outstanding voting power from obtaining control of the
board of directors until the second annual shareholders meeting following the
date the acquirer obtains the controlling share interest. The classified board
provision could have the effect of discouraging a potential acquirer from
making a tender offer or otherwise attempting to obtain control of the Company
and could thus increase the likelihood that incumbent directors will retain
their positions.
 
  Preemption Rights. No holder of shares of the Company shall, by reason of
such holding, have any preemptive right to subscribe to any additional issue
of shares of any class or series nor to any security convertible into such
shares.
 
  Transfer of Shares. The Articles also provide that the board of directors
may suspend the registration of transfers of Ordinary Shares for such periods
as the board of directors may determine, but shall not suspend the
registration of transfers for more than 40 days.
 
  The existing holders of Ordinary Shares have agreed not to offer, sell,
contract to sell or otherwise dispose of, directly or indirectly, or announce
the offering of any Ordinary Shares, including any such Ordinary Shares
beneficially or indirectly owned or controlled by the Company, or any
securities convertible into, or exchangeable or exercisable for Ordinary
Shares, for 180 days from the date of this Prospectus, without the prior
written consent of Salomon.
 
OTHER CLASS OR SERIES OF SHARES
 
  The Articles authorize the directors to create and issue one or more classes
or series of shares and determine the rights and preferences of each such
class or series, to the extent permitted by the
 
                                      76
<PAGE>
 
Articles and applicable law. Among other rights, the directors may determine:
(i) the number of shares of that class or series and the distinctive
designation thereof; (ii) the voting powers, full or limited, if any, of the
shares of that class or series; (iii) the right in respect of dividends on the
shares of that class or series, whether dividends shall be cumulative and, if
so, from which date or dates and the relative rights or priority, if any, of
payment of dividends on shares of that class or series and any limitations,
restrictions or conditions on the payment of dividends; (iv) the relative
amounts, and the relative rights or priority, if any, of payment in respect of
shares of that class or series, which the holders of the shares of that class
or series shall be entitled to receive upon any liquidation, dissolution or
winding up of the Company; (v) the terms and conditions (including the price
or prices, which may vary under different conditions and at different
redemption dates), if any, upon which all or any part of the shares of that
class or series may be redeemed, and any limitations, restrictions or
conditions on such redemption; (vi) the terms, if any, of any purchase,
retirement or sinking fund to be provided for the shares of that class or
series; (vii) the terms, if any, upon which the shares of that class or series
shall be convertible into or exchangeable for shares of any other class,
classes or series, or other securities, whether or not issued by the Company;
(viii) the restrictions, limitations and conditions, if any, upon issuance of
indebtedness of the Company so long as any shares of that class or series are
outstanding; and (ix) any other preferences and relative, participating,
optional or other rights and limitations not inconsistent with applicable law
or the Articles.
 
REGISTRATION RIGHTS
 
  Silver Holdings, Argentum LLC, Consolidated Commodities Ltd., Aurum LLC,
Thomas Kaplan and the Company will enter into a registration rights and voting
agreement, dated as of    , 1997, pursuant to which each of Silver Holdings
and Argentum LLC are entitled to demand registration of any Ordinary Shares
owned by either of them. Silver Holdings and Argentum LLC may make such demand
up to three times each on Form S-1 or S-2 of the Securities Act and up to
three times each on Form S-3, when such form is available for use by the
Company. The Company is not required to effect any demand registration within
120 days after the effective date of a previous demand registration and may
postpone, on one occasion in any 365-day period, the filing or effectiveness
of a registration statement for a demand registration for up to 120 days under
certain circumstances, including pending material transactions. Silver
Holdings, Argentum LLC, Aurum LLC and Consolidated Commodities Ltd. are also
entitled to unlimited piggyback registrations. All such registrations would be
at the Company's expense, exclusive of underwriting discounts and commissions.
The Company and such shareholders have entered into customary indemnification
and contribution provisions.
 
TRANSFER AGENT
   
  The Company's registrar and transfer agent for all Ordinary Shares is
American Stock Transfer & Trust Company.     
 
DIFFERENCES IN CORPORATE LAW
 
  The Companies Law (1995 Revision) (the "Companies Law") of the Cayman
Islands is modeled after that of England, and differs in certain respects from
such laws generally applicable to United States corporations and their
shareholders. Set forth below is a summary of certain significant provisions
of the Companies Law (including such modifications thereto adopted pursuant to
the Articles) applicable to the Company which differ from provisions generally
applicable to United States corporations and their shareholders. These
statements are a brief summary of certain significant provisions of the
Companies Law and, as such, do not deal with all aspects of every law that may
be relevant to corporations and their shareholders.
 
  Interested Directors. The Company's Articles provide that any transaction
entered into by the Company in which a director has an interest is not
voidable by the Company nor can such director be liable to the Company for any
profit realized pursuant to such transaction. A director having an interest
 
                                      77
<PAGE>
 
in a transaction is entitled to vote in respect of such transaction provided
the nature of the interest is disclosed at or prior to the vote on such
transaction.
 
  Mergers and Similar Arrangements. The Company may acquire the business of
another company and carry on such business when it is within the objects of
the Memorandum. The approval of the holders of at least 75 percent of the
outstanding shares entitled to vote, voting together as a single class, at a
meeting called for such purpose is required for the Company to (i) merge,
consolidate or amalgamate with another company, (ii) reorganize or reconstruct
itself pursuant to a plan sanctioned by the Cayman Islands courts or (iii)
sell, lease or exchange all or substantially all of its assets, except in the
case of a transaction between the Company and any entity which the Company,
directly or indirectly, controls. In order to merge or amalgamate with another
company or to reorganize and reconstruct itself, as a general rule, the
relevant plan would need to be approved in accordance with the provisions of
the Companies Law by the holders of not less than 75 percent of the votes cast
at a general meeting called for such purpose and thereafter sanctioned by the
Cayman Islands court. In respect of such a court sanctioned reorganization,
while a dissenting shareholder may have the right to express to a Cayman
Islands court his view that the transaction sought to be approved would not
provide the shareholders with the fair value of their shares, (i) the court
ordinarily would not disapprove the transaction on that ground absent other
evidence of fraud or bad faith, and (ii) if the transaction were approved and
consummated, the dissenting shareholder would have no rights comparable to the
appraisal rights (as here defined, rights to receive payment in cash for the
judicially determined value of their shares) ordinarily available to
dissenting shareholders of United States corporations.
 
  Shareholders' Suits. There does not appear to be any history of either a
class action or a derivative action ever having been brought by shareholders
in the Cayman Islands courts. There has, however, until recently been no
official law reporting in the Cayman Islands and actions subject to the
Confidential Relationships (Preservation) Law of 1976, as amended, are held in
closed court. However, in this regard, the Cayman Islands courts ordinarily
would be expected to follow English precedent, which would permit a minority
shareholder to commence an action against or a derivative action in the name
of the corporation only (i) where the act complained of is alleged to be
beyond the corporate power of the corporation or illegal, (ii) where the act
complained of is alleged to constitute a fraud against the minority
perpetrated by those in control of the corporation, (iii) where the act
requires approval by a greater percentage of the corporation's shareholders
than actually approved it, or (iv) where there is an absolute necessity to
waive the general rule that a shareholder may not bring such an action in
order that there not be a denial of justice or a violation of the
corporation's memorandum of association.
 
  Indemnification; Exculpation. Cayman Islands law does not limit the extent
to which a company's Articles of Association may provide for the
indemnification of officers and directors, except to the extent that such
provision may be held by the Cayman Islands courts to be contrary to public
policy (for instance, for purporting to provide indemnification against the
consequences of committing a crime). In addition, an officer or director may
not be indemnified for fraud or wilful default.
 
  The Company's Articles contain provisions providing for the indemnity by the
Company of an officer, director, consultant, employee or agent of the Company
for threatened, pending or contemplated actions, suits or proceedings, whether
civil, criminal, administrative or investigative (including, without
limitation, an action by or the right of the company), brought against such
indemnified person by reason of the fact that such person was an officer,
director, consultant, employee or agent of the Company. In addition, the board
of directors may authorize the Company to purchase and maintain insurance on
behalf of any such person against any liability asserted against him and
incurred by him in any such capacity, or arising out of his status as such,
whether or not the company would have the power to indemnify him against such
liability under the provisions of the Articles.
 
 
                                      78
<PAGE>
 
  The Company also purchases directors and officers liability insurance from
third parties for its directors and officers. The Company's Article's provide
that directors and officers of the Company shall have no liability (i) for the
acts, receipts, neglects, defaults or omissions of any other such director or
officer or agent of the Company or (ii) by reason of his having joined in any
receipt for money not received by him personally or (iii) for any loss on
account of defect of title to any property of the Company or (iv) on account
of the insufficiency of any security in or upon which any money of the Company
shall be invested or (v) for any loss incurred through any bank, broker or
other agent or (vi) for any loss occasioned by any negligence, default, breach
of duty, breach of trust, error of judgement or oversight on his part of (vii)
for any loss, damage or misfortune whatsoever which may happen in or arise
from the execution or discharge of the duties, powers, authorities, or
discretions of his office or in relation thereto, unless the same shall happen
through his own dishonesty.
 
  Inspection of Books and Records. Shareholders of a Cayman Islands company
have no general rights to inspect or obtain copies of the list of shareholders
or corporate records of a corporation.
 
ANTI-TAKEOVER EFFECTS OF ARTICLES OF ASSOCIATION
 
  The Articles contain certain provisions that make more difficult the
acquisition of control of the Company by means of a tender offer, open market
purchase, a proxy fight or otherwise. These provisions are designed to
encourage persons seeking to acquire control of the Company to negotiate with
the directors. The directors believe that, as a general rule, the interests of
the Company's shareholders would be best served if any change in control
results from negotiations with the directors. The directors would negotiate
based upon careful consideration of the proposed terms, such as the price to
be paid to shareholders, the form of consideration to be paid and the
anticipated tax effects of the transaction. However, these provisions could
have the effect of discouraging a prospective acquirer from making a tender
offer or otherwise attempting to obtain control of the Company. To the extent
these provisions discourage takeover attempts, they could deprive shareholders
of opportunities to realize takeover premiums for their shares or could
depress the market price of the shares.
 
  In addition to those provisions of the Articles discussed above, set forth
below is a description of other relevant provisions of the Articles. The
descriptions are intended as a summary only and are qualified in their
entirety by reference to the Articles, which are filed as an exhibit to the
Registration Statement of which this Prospectus is a part.
 
  Shareholder Action by Written Consent. Cayman law permits shareholders to
act by unanimous written consent.
 
  Availability of Ordinary Shares of the Company for Future Issuances. The
availability for issue of shares by the directors of the Company without
further action by shareholders (except as may be required by applicable stock
exchange requirements) could be viewed as enabling the directors to make more
difficult a change in control of the Company, including by issuing warrants or
rights to acquire shares to discourage or defeat unsolicited share
accumulation programs and acquisition proposals and by issuing shares in a
Private Placement or public offering to dilute or deter share ownership of
persons seeking to obtain control of the Company. The Company has no present
plan to issue any shares other than possibly pursuant to employee benefit
plans.
 
  Shareholder Proposals. The Articles provide that if a shareholder desires to
submit a proposal for consideration at an annual general meeting or
extraordinary general meeting, or to nominate persons for election as
directors, written notice of such shareholder's intent to make such a proposal
or nomination must be given and received by the secretary of the Company at
the principal executive offices of the Company not later than (i) with respect
to an annual general meeting, 60 days prior to the anniversary date of the
immediately preceding annual general meeting, and (ii) with respect to an
extraordinary general meeting, the close of business on the tenth day
following the date on which notice of such meeting is first sent or given to
shareholders. The notice must describe the proposal or
 
                                      79
<PAGE>
 
nomination in sufficient detail for a proposal or nomination to be summarized
on the agenda for the meeting and must set forth (i) the name and address of
the shareholder, (ii) a representation that the shareholder is a holder of
record of shares of the Company entitled to vote at such meeting and intends
to appear in person or by proxy at the meeting to present such proposal or
nomination, and (iii) the class and number of shares of the Company which are
beneficially owned by the shareholder. In addition, the notice must set forth
the reasons for conducting such proposed business at the meeting and any
material interest of the shareholder in such business. In the case of a
nomination of any person for election as a director, the notice shall set
forth: (i) the name and address of any person to be nominated; (ii) a
description of all arrangements or understandings between the shareholder and
each nominee and any other person or persons; (iii) such other information
regarding such nominee proposed by such shareholder as would be required to be
included in a proxy statement filed pursuant to Regulation 14A under the
Exchange Act, whether or not the Company is then subject to such Regulation;
and (iv) the consent of each nominee to serve as a director of the Company, if
so elected. The presiding officer of the annual general meeting or
extraordinary general meeting shall, if the facts warrant, refuse to
acknowledge a proposal or nomination not made in compliance with the foregoing
procedure.
 
  The advance notice requirements regulating shareholder nominations and
proposals may have the effect of precluding a contest for the election of
directors or the introduction of a shareholder proposal if the procedures
summarized above are not followed and may discourage or deter a third party
from conducting a solicitation of proxies to elect its own slate of directors
or to introduce a proposal.
 
                                      80
<PAGE>
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
  After consummation of the Offering, there will be [   ] Ordinary Shares
still owned by the current shareholders of the Company. Approximately
7,077,007 Ordinary Shares may be issued to the Minority Shareholders on a one-
for-one basis for the shares of Apex LDC subject to the terms of the Buy-Sell
Agreement. See "Certain Transactions". Shareholders will only be able to sell
such Ordinary Shares pursuant to a registration statement under the Securities
Act or an exemption therefrom.
 
  Rule 144 under the Securities Act provides such an exemption for resales of
securities under certain circumstances. Under Rule 144, as currently in
effect, a person (or persons whose shares are aggregated) who beneficially
owns "restricted" shares that have been issued and not held by an affiliate of
the Company for at least one year from the time the shares were fully paid for
will be entitled to sell in "brokers' transactions" or to market makers,
within any three-month period, a number of shares that does not exceed the
greater of (i) one percent of the shares then outstanding or (ii) the average
weekly trading volume of the shares on all national securities exchanges
and/or reported through the automated quotation system of a registered
securities association during the four calendar weeks preceding such sale.
Sales under Rule 144 are also subject to certain notice requirements, and the
availability of current public information about the Company. Restricted
shares held for two years by a person who is not, at the time of sale and has
not been at any time within three months prior thereto, an affiliate of the
Company may be sold without regard to the volume limitations or manner of sale
restrictions under Rule 144. The foregoing summary of Rule 144 is not intended
to be a complete description thereof.
 
  The existing holders of Ordinary Shares have agreed with the representatives
of the U.S. Underwriters subject to certain exceptions, not to register any
transfer of such shares, without the consent of Salomon until at least the
date 180 days from the date of this Prospectus. See "Underwriting".
 
  In addition, after the Offering approximately [   ] Ordinary Shares
(including all Ordinary Shares issuable pursuant to the Buy-Sell Agreement)
will be entitled to certain rights with respect to registration of such Shares
under the Securities Act. See "Description of Ordinary Shares--Registration
Rights".
 
  There has been no public market in the shares prior to the Offering and no
predictions can be made as to the effect, if any, that additional sales of
Ordinary Shares in the future by any Shareholders or the availability of such
Ordinary Shares for sale will have on the market price prevailing from time to
time. Sales of substantial amounts of additional Ordinary Shares in the public
market, or the perception that such sales could occur, could adversely affect
prevailing market prices and the Company's ability to raise additional equity
capital (although the Company has no current plans to do so).

  The Company has been advised by the U.S. Representatives that the several
U.S. Underwriters initially propose to offer such Shares to the public at the
Price to Public set forth on the cover page of this Prospectus and to certain
dealers at such price less a concession not in excess of $[   ] per Share. The
U.S. Underwriters may allow, and such dealers may re-allow, a concession not
in excess of $[   ] per Share to other dealers. After the Offerings, the Price
to Public and such concessions may be changed.
 
  The Company has granted to the U.S. Underwriters and the Managers
(collectively, the "Underwriters") options, exercisable during the 30-day
period after the date of this Prospectus, to purchase up to [   ] additional
Shares from the Company at the Price to Public less the Underwriting Discount,
solely to cover over-allotments. To the extent that the U.S. Underwriters and
the Managers exercise such options, each of the U.S. Underwriters and the
Managers, as the case may be, will be committed, subject to certain
conditions, to purchase a number of option shares proportionate to such U.S.
Underwriter's or Manager's initial commitment.
 
  The Company has entered into an International Underwriting Agreement with
the Managers named therein, for whom Salomon Brothers International Limited,
PaineWebber International (U.K.) Limited and ABN AMRO Rothschilds are acting
as the representatives (the "International Representatives" and, together with
the U.S. Representatives, the "Representatives"), providing for the concurrent
offer and sale of [   ] Shares (in addition to the shares covered by the over-
allotment options described above) outside the U.S. and Canada. Both the U.S.
Underwriting Agreement and the International Underwriting Agreement provide
that the obligations of the U.S. Underwriters and the Managers are such that
if any of the Shares are purchased by the U.S. Underwriters pursuant to the
U.S. Underwriting Agreement, or by the Managers pursuant to the International
Underwriting Agreement, all the Shares agreed to be purchased by either the
U.S. Underwriters or the Managers, as the case may be, pursuant to their
respective agreements must be so purchased. The Price to Public and
Underwriting Discount per Share for the U.S. Offering and International
Offering will be identical. The closing of the International Offering is a
condition to the closing of the U.S. Offering and the closing of the U.S.
Offering is a condition to the closing of the International Offering.
 
  Each U.S. Underwriter has severally agreed that, as part of the distribution
of the [   ] Shares offered by the U.S. Underwriters: (i) it is not purchasing
any Shares for the account of anyone other than a U.S. or Canadian Person;
(ii) it has not offered or sold, and will not offer or sell, directly or
indirectly, any Shares or distribute this Prospectus to any person outside of
the U.S. or Canada, or to anyone other than a U.S. or Canadian Person; and
(iii) any dealer to whom it may sell any Shares will
 
                                      82
<PAGE>
 
represent that it is not purchasing for the account of anyone other than a
U.S. or Canadian Person and agree that it will not offer or resell, directly
or indirectly, any Shares outside of the U.S. or Canada, or to anyone other
than a U.S. or Canadian Person or to any other dealer who does not so
represent and agree. Each Manager has severally agreed that, as part of the
distribution of the [   ] Shares offered by the Managers: (i) it is not
purchasing any Shares for the account of any U.S. or Canadian Person; (ii) it
has not offered or sold, and will not offer or sell, directly or indirectly,
any Shares or distribute any Prospectus relating to the International Offering
to any person in the U.S. or Canada, or to any U.S. or Canadian Person; and
(iii) any dealer to whom it may sell any Shares will represent that it is not
purchasing for the account of any U.S. or Canadian Person and agree that it
will not offer or resell, directly or indirectly, any Shares in the U.S. or
Canada, or to any U.S. or Canadian Person or to any other dealer who does not
so represent and agree.
 
  The foregoing limitations do not apply to stabilization transactions or to
certain other transactions specified in the Agreement Between U.S.
Underwriters and the Managers. "U.S. or Canadian Person" means any person who
is a national or resident of the U.S. or Canada, any corporation, partnership
or other entity created or organized in or under the laws of the U.S. or
Canada or of any political subdivision thereof, and any estate or trust the
income of which is subject to U.S. or Canadian federal income taxation,
regardless of its source (other than any non-U.S. or non-Canadian branch of
any U.S. or Canadian Person), and includes any U.S. or Canadian branch of a
person other than a U.S. or Canadian Person.
 
  Pursuant to the Agreement Between U.S. Underwriters and the Managers, sales
may be made between the U.S. Underwriters and the Managers of such number of
Shares as may be mutually agreed. The price of any Shares so sold shall be the
Price to Public, less an amount not greater than the concession to securities
dealers. To the extent that there are sales between the U.S. Underwriters and
the Managers pursuant to the Agreement Between U.S. Underwriters and the
Managers, the number of Shares initially available for sale by the U.S.
Underwriters or by the Managers may be more or less than the amount specified
on the cover page of this Prospectus.
 
  Any offer of the Shares in Canada will be made only pursuant to an exemption
from the prospectus filing requirement and an exemption from the dealer
registration requirement (where such an exemption is not available, offers
shall be made only by a registered dealer) in the relevant Canadian
jurisdiction where such offer is made.
 
  The U.S. Underwriting Agreement provides that the Company will indemnify the
U.S. Underwriters against certain liabilities and expenses, including
liabilities under the Securities Act, or contribute to payments the U.S.
Underwriters may be required to make in respect thereof.
 
  The International Underwriting Agreement provides that the Company will
indemnify the Managers against certain liabilities and expenses.
 
  The existing holders of Shares have agreed not to offer, sell, contract to
sell or otherwise dispose of, directly or indirectly, or announce the offering
of any Shares, including any such Shares beneficially or indirectly owned or
controlled by the Company, or any securities convertible into, or exchangeable
or exercisable for Shares, for 180 days from the date of this Prospectus,
without the prior written consent of Salomon.
 
  During and after the Offerings, the Underwriters may purchase and sell the
Shares in the open market. These transactions may include overallotment and
stabilizing transactions and purchases to cover syndicate short positions
created in connection with the Offerings. The Underwriters also may impose a
penalty bid, whereby selling concessions allowed to syndicate members of other
broker-dealers, in respect of the Shares sold in the Offerings for their
account may be reclaimed by the syndicate if such Shares are repurchased by
the syndicate in stabilizing or covering transactions. These activities may
stabilize, maintain or otherwise affect the market price of the Shares which
may be higher than the price that might otherwise prevail in the open market.

  Prior to the Offerings, there has been no public market for the Shares. The
Price to Public was determined by negotiations between the Company and the
Representatives. Among the factors considered in determining the Price to
Public were prevailing market conditions, the market values of publicly traded
companies that the Underwriters believed to be somewhat comparable to the
Company, the demand for the Shares and for similar securities of publicly
traded companies that the Underwriters believed to be somewhat comparable to
the Company, the future prospects of the Company and its industry in general,
sales, earnings and certain other financial and operating information of the
Company in recent periods, and other factors deemed relevant. There can be no
assurance that the prices at which the Shares will sell in the public market
after the Offerings will not be lower than the Price to Public.
 
  Certain of the U.S. Underwriters and Managers provide financial advisory
services to or are engaged in other financial transactions with the Company
for which they have received and will receive customary compensation. The
Company has retained N.M. Rothschild & Sons Limited, an affiliate of ABN AMRO
Rothschilds, to act as the Company's financial advisor in connection with the
anticipated project financing with respect to the San Cristobal Project. The
Company has engaged Salomon and Credit Suisse First Boston to act as the
Company's financial advisors with respect to the identification of, and
negotiation with, potential joint venture mining partners in the San Cristobal
Project. The Company has paid Salomon and Credit Suisse First Boston financial
advisory fees and has agreed to pay them monthly advisory fees and success-
based transaction fees, and to reimburse their respective out-of-pocket
expenses. The Company has also agreed to indemnify Salomon and Credit Suisse
First Boston against certain liabilities.

                                   TAXATION
   
  The following discussion is a summary of the material Cayman Islands and
U.S. federal income tax consequences of the acquisition, ownership and
disposition of Shares. The discussion is based on the Code and the tax laws of
the Cayman Islands as in effect on the date hereof, which are subject to
change. The discussion does not consider any specific facts or circumstances
that may apply to a particular investor, some of which (for example, tax-
exempt entities, insurance companies, banks, broker-dealers, investors liable
for alternative minimum tax, investors who hold Shares as part of straddles or
hedging or conversion transactions or constructive sales, and investors whose
functional currency is not the U.S. dollar) may be subject to special rules.
In addition, the discussion does not address special rules that could in
certain circumstances apply to a U.S. Holder (as defined below) of Shares that
owns directly or by attribution 10 percent or more of the Ordinary Shares.
Because the discussion is not exhaustive of all possible tax considerations
relevant to the ownership of Shares and is not based upon an opinion of
counsel, prospective investors are urged to consult their tax advisors
regarding the U.S. federal, state, local and foreign tax consequences,
including the Cayman Islands tax consequences, of the acquisition, ownership
and disposition of Shares in their particular circumstances.     
 
CAYMAN ISLANDS TAXATION
 
  There is, at present, no direct income taxation in the Cayman Islands.
Accordingly, income and gains received by the Company, and distributions by
the Company to its shareholders and gains realized upon the disposition of
Shares, will be received free of all Cayman Islands income and withholding
taxes. The Company is registered as an exempted Company under Cayman Islands
law, and the Company has received an undertaking from the Governor-in-Council
of the Cayman Islands to the effect that, for a period of 20 years from the
date of the undertaking, no law that is enacted in the Cayman Islands imposing
any tax to be levied on profits or income or gains or appreciations will apply
to the Company nor shall any tax in the nature of estate duty or inheritance
tax be payable on the shares, debentures or other obligations of the Company.
 
UNITED STATES FEDERAL INCOME TAXATION
 
  For purposes of this discussion, a "U.S. Holder" is any beneficial owner
that owns Shares as a capital asset and is (i) a citizen or resident of the
U.S., (ii) a corporation or partnership that is created or organized in the
U.S. or under the law of the U.S. or any state thereof, (iii) an estate that
is subject to U.S. federal income tax on its income regardless of source, or
(iv) a trust if a court within the U.S. is able to exercise primary
supervision over the administration of the trust and one or more U.S.
fiduciaries have authority to control all substantial decisions of the trust.
 
TAXATION OF DIVIDENDS
 
  Subject to the discussion under "Passive Foreign Investment Company
Considerations" and "Foreign Personal Holding Company Considerations", under
U.S. federal income tax law, U.S. Holders will include in gross income as a
dividend the gross amount of any distribution paid by the Company to the
extent of its current or accumulated earnings and profits (as determined for
U.S. federal income tax purposes) as ordinary income when the dividend is
received by the U.S. Holder. The dividend will not be eligible for the
dividends-received deduction generally allowed to U.S. corporations. In
general, the dividend will be income from sources outside the U.S., and
generally will be treated together with other items of "passive income" (or,
in the case of certain holders, "financial services income") for U.S. foreign
tax credit purposes.
 
TAXATION OF CAPITAL GAINS
 
  Subject to the discussion under "Passive Foreign Investment Company
Considerations", upon a sale or other disposition of Shares, a U.S. Holder
will recognize gain or loss for U.S. federal income
 
                                      85
<PAGE>
 
tax purposes in an amount equal to the difference between the U.S. dollar
value of the amount realized and the U.S. Holder's tax basis (determined in
U.S. dollars) in such Shares. Such gain or loss will be capital gain or loss
and, if the U.S. Holder's holding period for such Shares exceeds 18 months,
will be long-term capital gain or loss.
 
PASSIVE FOREIGN INVESTMENT COMPANY CONSIDERATIONS
 
  Classification as a PFIC. The Company will be a PFIC for any taxable year if
75 percent or more of its gross income for the taxable year is "passive"
income or 50 percent or more of its assets produce or are held for the
production of "passive" income. For purposes of applying these income and
asset tests, the Company is deemed to receive its pro rata share of the
income, and to own its pro rata share of the assets, of any corporation in
which the Company directly or indirectly owns 25 percent or more of the stock
(measured by value). In addition, although not free from doubt, it is expected
that the Company will be deemed to receive its pro rata share of the income,
and to own its pro rata share of the assets, of any partnership in which the
Company is a partner (either directly or through one or more intervening
partnerships). U.S. Holders should be aware that the Shares may be treated as
stock of a passive foreign investment company ("PFIC") for U.S. federal income
tax purposes because the Company will earn significant passive income from
investments relative to any non-passive income of the Company prior to the
commencement by the Company of substantial mining operations. Further, the
Code treats gains from transactions in commodities, such as silver, as passive
income for PFIC purposes unless "substantially all" of a company's business is
as an active producer of the commodity. Applicable U.S. Treasury Regulations
interpret "substantially all" to mean that 85 percent or more of a producer's
taxable income must be gross receipts from sales in the active conduct of a
commodities business or certain related activities. Under these rules, there
can be no assurance that the Company would not be treated as a PFIC in future
taxable years even after it has begun to earn income from mining operations.
In this regard, prospective investors should note that the Company would
likely constitute a PFIC even after it begins to generate significant income
from mining operations in the event the Company conducts its mining operations
predominantly through the use of independent contractors rather than directly
through the use of its own employees.
 
  Prospective investors should note that the PFIC classification rules are
complex and may apply in numerous unexpected circumstances. Under these rules,
the Company could be classified as a PFIC in various circumstances in addition
to those described in the preceding paragraphs. For example, the Company could
constitute a PFIC for any taxable year as a consequence of owning substantial
"passive assets" such as cash and marketable securities (including any cash
derived from the issuance of Company securities or the sale of assets of the
Company), even in a year in which the Company generates significant income
from direct mining operations.
 
  Consequences of PFIC Status. If the Company were treated as a PFIC, unless a
U.S. Holder makes a "QEF election" or "mark to market election" in respect of
the Company, as described below, such U.S. Holder will be subject to a special
tax regime (i) in respect of gains realized on the sale or other disposition
of Shares, and (ii) in respect of distributions on Shares held for more than
one taxable year to the extent those distributions constitute "excess
distributions". Although not entirely free from doubt, the PFIC rules should
not apply to gain realized in respect of any Shares disposed of during the
same taxable year in which the Shares are acquired. An excess distribution
generally includes dividends or other distributions received from a PFIC in
any taxable year to the extent the amount of such distributions exceeds 125
percent of the average distributions for the three preceding years (or, if
shorter, the investor's holding period). In general, under the PFIC rules, a
U.S. Holder will be required to allocate such excess distributions and any
gain realized on sale of the Shares to each day during the Holder's holding
period for the Shares, and will be taxable at the highest rate of taxation
applicable to ordinary income for the year to which the excess distribution or
gain is allocable (without regard to the U.S. Holder's other items of income
and loss for such taxable year) (the "deferred tax"). The deferred tax (other
than the tax on amounts allocable to the year of disposition or receipt of the
 
                                      86
<PAGE>
 
distribution) will then be increased by an interest charge computed by
reference to the rate generally applicable to underpayments of tax (which
interest charge generally will be non-deductible interest expense for
individual taxpayers).
 
  QEF Election. The special PFIC tax rules described above will not apply to a
U.S. Holder if the U.S. Holder elects to have the Company treated as a
"qualified electing fund" ("QEF election") in the first taxable year of the
holder's ownership of the Shares during which the Company is a PFIC and the
Company complies with certain reporting requirements. The Company intends to
comply with all reporting requirements necessary for U.S. Holders to make a
QEF election with respect to the Company and will upon request provide to U.S.
Holders such information as may be required to make such QEF election
effective.
 
  A U.S. Holder that makes a QEF election with respect to the Company will be
currently taxable on its pro rata share of ordinary earnings and net capital
gain of the Company for each taxable year of the Company in which the Company
qualifies as a PFIC, regardless of whether the holder receives any
distribution from the Company. The U.S. Holder's basis in the Shares of the
Company will be increased to reflect taxed but undistributed income of the
Company. Distributions of income that previously had been taxed will result in
a corresponding reduction of basis in the Shares and will not be taxed again
as a distribution to the U.S. Holder.
 
  During the period in which the Company may be a PFIC, the Company may be
entitled to deductions under U.S. federal income tax principles that may
substantially offset earnings of the Company. As a result, the pro rata share
of the ordinary earnings and net capital gain of the Company that would be
includable by a U.S. Holder making a QEF election may not be material. If this
were the case, U.S. Holders generally could obtain the benefits of making a
QEF election in respect of the Company (i.e., the elimination of deferred tax
and interest charges on excess distributions and realized gains) without
having to bear current inclusions of income substantially in excess of
distributions received. U.S. Holders should consult their own tax advisors
concerning the most appropriate manner in which to make a QEF election.
 
  Lower-Tier PFICs. At the present time, none of the Company's non-U.S.
subsidiaries is classified as a corporation for U.S. federal income tax
purposes. Accordingly, U.S. Holders are not subject to the PFIC rules with
respect to their indirect ownership interests in these subsidiaries.
 
  If, in the future, the Company acquires a non-U.S. subsidiary that is
classified as a corporation for U.S. federal income tax purposes, the Company
will notify its shareholders so that U.S. Holders may determine whether to
make a QEF election with respect to the subsidiary. If the Company were a
PFIC, U.S. Holders generally would be deemed to own, and also would be subject
to the PFIC rules with respect to, their indirect ownership interests in any
corporate subsidiaries of the Company which themselves constitute PFICs
("lower-tier PFICs"). If the Company were a PFIC and a U.S. Holder does not
make a QEF election in respect of any lower-tier PFIC, the U.S. Holder could
incur liability for the deferred tax and interest charge described above if
either (i) the Company receives a distribution from, or disposes of all or
part of its interest in, a lower-tier PFIC or (ii) the U.S. Holder disposes of
all or part of its Shares. The Company intends to cause any lower-tier PFIC to
comply with all reporting requirements necessary for a U.S. Holder to make a
QEF election with respect to the lower-tier PFIC.
 
  Mark to Market Election. For taxable years beginning after December 31,
1997, a U.S. Holder who owns marketable stock of a PFIC may elect to recognize
any gain or loss on the stock on a mark-to-market basis at the end of the U.S.
Holder's taxable year. If an election is made, any mark-to-market gains, and
any gains realized on disposition of the stock, will be treated as ordinary
income. Mark-to-market losses, and any losses recognized on disposition of the
stock to the extent of the holder's net mark-to-market gains, will be treated
as ordinary losses. U.S. Holders should consult their tax advisors regarding
the effect of making a mark-to-market election with respect to the Shares,
including the effect of such an election on any lower-tier PFICs that the
holder is deemed to own.
 
                                      87
<PAGE>
 
  A U.S. Holder who owns Shares during any year that the Company is a PFIC
must file an Internal Revenue Service Form 8621 in respect of such Shares and,
under proposed U.S. Treasury Regulations, in respect of interests in any
lower-tier PFICs.
 
  Prospective investors are urged to consult their own tax advisors regarding
the possible classification of the Company as a PFIC as well as the potential
tax consequences arising from the ownership and disposition (directly or
indirectly) of interests in a PFIC.
 
FOREIGN PERSONAL HOLDING COMPANY CONSIDERATIONS
 
  Prospective investors should also be aware that special U.S. tax laws would
apply to U.S. Holders if the Company (or any corporate subsidiary of the
Company) is characterized as a foreign personal holding company ("FPHC"). In
particular, if the Company (or any corporate subsidiary) is an FPHC in respect
of any taxable year of the Company, U.S. Holders may be subject to current tax
on their (direct or indirect) pro rata share of the income of the FPHC (as
determined for purposes of the FPHC rules), even if no cash dividend is
actually paid by the FPHC. In general, the Company (or any corporate
subsidiary of the Company) will constitute a FPHC during a taxable year if (i)
a specified percentage of its income is passive for purposes of the FPHC
rules, and (ii) at any time during the taxable year five or fewer individuals
who are U.S. citizens or residents own (directly, indirectly or
constructively) more than 50 percent of the voting power or value of such
company's stock. The Company does not anticipate that it or any of its
subsidiaries will be an FPHC immediately following the Offering or in the
future. The Company, however, can provide no assurance as to such conclusion.
 
TAXATION OF NON-U.S. HOLDERS
 
  An investor who is not a U.S. Holder will not be subject to U.S. federal
income tax on any dividends received on the Shares unless (i) the investor has
an office or other fixed place of business in the U.S. to which the dividends
are attributable and either the dividends are derived in the active conduct of
a banking, finance or similar business in the U.S. or the investor is a non-
U.S. corporation the principal business of which consists of trading in stocks
or securities for its own account and certain other conditions are met or (ii)
the investor is a foreign insurance company that conducts business in the U.S.
and the dividends are attributable to such business.
 
  An investor who is not a U.S. Holder will not be subject to U.S. federal
income tax on any gain realized on the sale or other disposition of Shares
unless (i) the investor is engaged in the conduct of a trade or business in
the U.S. and the gain is effectively connected with such trade or business or
(ii) the investor is an individual who is present in the U.S. for 183 days or
more during the taxable year in which the gain is realized and certain other
conditions are met.
 
UNITED STATES INFORMATION REPORTING AND BACKUP WITHHOLDING
 
  Under current U.S. federal income tax law, payments of dividends to certain
U.S. Holders are subject to information reporting, and a "back up" withholding
tax at a rate of 31 percent if such persons fail to supply correct taxpayer
identification numbers and certain other information in the required manner.
Payments of dividends to a U.S. Holder (a) made by mail or wire transfer to an
address in the U.S. , (b) made by a paying agent, broker or other intermediary
in the U.S. or (c) made by a U.S. broker or by a custodian, nominee or agent
that is (i) a U.S. person, (ii) a controlled foreign corporation for U.S. tax
purposes, or (iii) a foreign person 50% or more of whose gross income is from
a U.S. trade or business (hereinafter, any of the persons described in (i),
(ii) and (iii) shall be referred to as a "U.S. Controlled Person") to such
holder outside the U.S. may be subject to U.S. information reporting
requirements. Payments of dividends received by investors who are not U.S.
Holders generally would be exempt from these reporting requirements, but such
persons may be required to comply with certification and identification
procedures in order to prove their exemption from the reporting requirements.
Treasury regulations currently in effect do not require backup withholding
with respect to dividends paid by a foreign corporation such as the Company.
 
                                      88
<PAGE>
 
  The payment of proceeds of the disposition of Shares by a holder to or
through the U.S. office of a broker generally will be subject to information
reporting and backup withholding at a rate of 31 percent, unless the holder
either certifies its status as a non-U.S. Holder under penalties of perjury or
otherwise establishes an exemption. The payment of proceeds of the disposition
by a holder of Shares to or through a non-U.S. office of a broker will
generally not be subject to backup withholding and information reporting.
However, information reporting (but not backup withholding) may apply to such
a holder who sells a beneficial interest in Shares through a non U.S. branch
of a U.S. broker, or through a non-U.S. office of a U.S. Controlled Person, in
either case unless the holder establishes an exemption or the broker has
documentary evidence in its files of the holder's status as a non-U.S. person.
 
  Any amounts withheld under the backup withholding rules from payment to a
holder will be refunded (or credited against the holder's United States
federal income tax liability, if any) provided that the required information
is furnished to the United States Internal Revenue Service.

minerals leaving a "concentrate" of metal and/or metal minerals with a
consequent order of magnitude higher content of metal and/or metal minerals
than the beginning ore material.

  PROBABLE RESERVES--reserves for which quantity and grade and/or quality are
computed from information similar to that used for proven reserves (see
below), but the sites for inspection, sampling and measurement are farther
apart or are otherwise less adequately spaced. The degree of assurance,
although lower than that for proven reserves, is high enough to assume
continuity between points of observation.
   
  PROPYLITIC ALTERATION--a hydrothermally altered rock containing chlorite,
pyrite, and carbonate.     
 
  PROVEN RESERVES--reserves for which (a) quantity is computed from dimensions

  In our opinion, the accompanying consolidated balance sheet and the related
consolidated statements of operations, of changes in shareholders' equity and
of cash flows present fairly, in all material respects, the financial position
of Apex Silver Mines Limited (successor to Apex Silver Mines LDC) and its
subsidiaries at December 31, 1996 and 1995 and the results of their operations
and their cash flows for the years ended December 31, 1996 and 1995, the
period from December 22, 1994 (inception) through December 31, 1994 and the
period from inception through December 31, 1996 in conformity with generally
accepted accounting principles. These financial statements are the
responsibility of the Company's management; our responsibility is to express
an opinion on these financial statements based on our audits. We conducted our
audits of these statements in accordance with generally accepted auditing
standards which require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of
material misstatement. An audit includes examining, on a test basis, evidence
supporting the amounts and disclosures in the financial statements, assessing
the accounting principles used and significant estimates made by management,
and evaluating the overall financial statement presentation. We believe that
our audits provide a reasonable basis for the opinion expressed above.

                NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS
                     (EXPRESSED IN UNITED STATES DOLLARS)
 
1.INCORPORATION, RECAPITALIZATION, OWNERSHIP AND OPERATIONS
 
 a. Apex Silver Mines Limited ("Apex Limited" or the "Company") was formed
under the laws of the Cayman Islands in March of 1996 for the sole purpose of
serving as a holding company for certain ownership interests in Apex Silver
Mines LDC ("Apex LDC"). On April 15, 1996, holders of approximately 55% of the
then-outstanding shares of Apex LDC elected to participate, effective as of
the completion of a proposed private placement of shares of Apex Limited which
was completed as of August 6, 1996, in a recapitalization effected by an
exchange, on a one-for-one basis, of their shares in Apex LDC for identical
equity instruments of Apex Limited (the "Recapitalization"). The balance of
shareholders retained a direct ownership interest in Apex LDC. As a result of
this recapitalization, Apex LDC became a majority-owned subsidiary of Apex
Limited. The accompanying financial statements reflect the historical accounts
of the Company's predecessor, Apex LDC. For purposes of the accompanying
consolidated financial statements of Apex Limited, the recapitalization has
been given retroactive effect to the date of incorporation of Apex LDC, with
the results of operations and equity attributable to the other ownership
interests in Apex LDC being reflected in "minority interest in consolidated
subsidiary". Consequently, for purposes of these financial statements, Apex
Limited is considered the successor to Apex LDC.
 
 b. In August of 1996, Apex Limited issued 4,256,700 ordinary shares in a
private placement transaction (the "Private Placement") for net proceeds of
$32.4 million. These proceeds were contributed to Apex LDC in exchange for the
issuance by Apex LDC of 4,256,700 shares of its share capital. As a result of
this private placement, the Company's ownership interest in Apex LDC was
increased from approximately 55% to 65%.
 
 c. Apex LDC was incorporated under the laws of the Cayman Islands on November
23, 1994 as a 30-year limited duration company on the contribution of all the
assets of its predecessor entity, Apex Silver Mines Ltd., a Bermuda
corporation. (Actual contribution occurred on December 22, 1994.) The activity
of the predecessor has not been presented herein as it was immaterial.
However, all expenses incurred by the predecessor have been presented. The
Company's principal activity is the exploration of mineral properties. The
Company participates in the acquisition and exploration of mineral properties
for possible future development directly and indirectly through Apex LDC's
principal subsidiaries, Andean Silver Corporation LDC ("Andean"), ASC Bolivia
LDC ("ASC Bolivia"), Apex Asia LDC ("Apex Asia"), Minera de Cordilleras
(Honduras), S. de R.L. ("Cordilleras Honduras"), Cordilleras Silver Mines Ltd.
("Cordilleras Bahamas"), Cordilleras Silver Mines (Cayman) LDC ("Cordilleras
Cayman"), Compania Minerales de Zacatecas, S. de R.L. de C.V. ("CMZ"), Apex
Silver Mines Corporation, ("Apex Corporation") and ASC Peru LDC ("ASC Peru").
 
 
 d. In conjunction with the Recapitalization and the Private Placement, Apex
Limited and the shareholders of Apex LDC entered into a Buy-Sell Agreement
(the "Buy-Sell Agreement") which is intended to maintain the same beneficial
interest in Apex LDC attributable to all shareholders of Apex LDC prior to the
Recapitalization and Private Placement. Pursuant to the terms of the Buy-Sell
Agreement, upon a request by a shareholder of Apex LDC, Apex Limited is
required to purchase, at its sole option, for cash, for ordinary shares or for
a combination thereof, the shares of Apex LDC owned by such shareholder. Apex
Limited currently expects that any purchase of shares of Apex LDC will involve
only an equal number of ordinary shares. As of August 29, 1997, Apex Limited
has approximately 13,601,544 shares outstanding and approximately 7,077,007
ordinary shares reserved

          NOTES TO THE CONSOLIDATED FINANCIAL STATEMENTS--(CONTINUED)
                     (EXPRESSED IN UNITED STATES DOLLARS)

for issuance for the approximately 7,077,007 shares of Apex LDC owned by such
shareholders. If all such ordinary shares were issued, the Company would have
approximately 20,678,551 ordinary shares outstanding. Because of the
provisions of the Buy-Sell Agreement, all of the outstanding shares of Apex
LDC are considered ordinary share equivalents for purposes of computing net
loss per ordinary share but are not included in the computation for any of the
periods presented because they are antidilutive. If all of the Apex LDC shares
were assumed to be purchased in all periods, the outstanding ordinary shares
and the net loss per ordinary share as of and for the periods ended June 30,
1997 and 1996 and December 31, 1996, 1995 and 1994, on a pro forma basis,
would have been (all unaudited) 20,271,460, 15,899,553, 17,673,178, 15,899,553
and 15,899,553 ordinary shares and $(0.55), $(0.21), $(0.66), $(0.12) and
$(0.01) net loss per ordinary share.
 
 e. The Company, through its direct and indirect subsidiaries, is active in
Central America, South America and Central Asia and currently holds interests
in, or is the beneficial owner of, non-producing silver resource properties in
Chile, Bolivia, Honduras, Kyrghyzstan, Mexico, Mongolia, Peru and Tajikistan.
The Company is in the process of evaluating its properties to determine
economic feasibility of bringing one or more of the properties into
production.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  These consolidated financial statements have been prepared in accordance
with accounting principles generally accepted in the United States of America
("GAAP"). The preparation of financial statements in conformity with GAAP
requires management to make estimates and assumptions that affect the reported
amounts and disclosures in the financial statements. Actual results could
differ from those estimates. The policies adopted, considered by management to
be significant, are summarized as follows:
 
 a. Basis of consolidation
 
  These consolidated financial statements include the accounts of the Company
and its majority owned subsidiaries. Investment in 50% joint ventures are
proportionately consolidated.
 
 b. Interim financial data
 
  The interim financial data as of June 30, 1997 and for the six-month periods
ended June 30, 1997 and 1996 are unaudited; however, in the opinion of
management, such interim data includes all adjustments (consisting only of
normal recurring adjustments) considered necessary for a fair presentation of
financial position and results of operations for the interim periods. All data
included herein as of such date and for such periods are unaudited.
 
 c. Translation of foreign currencies
 
  All expenditures are made in United States dollars. Accordingly, the Company
uses the United States dollar as its functional currency.

                     (EXPRESSED IN UNITED STATES DOLLARS)
 
 d. Cash, cash equivalents and short-term investments
 
  The Company considers all highly liquid investments with a maturity of three
months or less when purchased to be cash equivalents. Short-term investments
include certificates of deposit with maturities greater than three months, but
not exceeding six months. Short-term investments are recorded at cost which
approximates fair value.
 
 e. Exploration and development costs
 
  The Company expenses general prospecting costs and the costs of acquiring
and exploring unevaluated mining properties. When a property is determined to
have proven and probable reserves, further exploration costs and development
costs are capitalized. When commercially profitable ore reserves are developed
and operations commence, capitalized costs will be amortized using the units-
of-production method. Upon abandonment or sale of projects, all capitalized
costs relating to the specific project are written off in the year abandoned
or sold and a gain or loss is recognized.
 
  As of December 31, 1996, no exploration and development costs have been
capitalized.
 
 f. Fixed assets
 
  Buildings and equipment are carried at cost and are depreciated on a
straight-line basis over estimated useful lives of three to thirty years.
 
 g. Deferred organizational costs
 
  Costs incurred in the organization of the Company have been capitalized and
are being amortized on a straight-line basis over five years.
 
 h. Asset impairment
 
  The Company evaluates its long-lived assets for impairment when events or
changes in circumstances indicate that the related carrying amount may not be
recoverable. If the sum of estimated future net cash flows on an undiscounted
basis is less than the carrying amount of the related asset, an asset
impairment is considered to exist. The related impairment loss is measured by
comparing estimated future net cash flows on a discounted basis to the
carrying amount of the asset. Changes in significant assumptions underlying
future cash flow estimates may have a material effect on the Company's
financial position and results of operations. To date no such impairments have
been identified.
 
 i. Fair value of financial instruments
 
  The Company's financial instruments consist of cash, receivables, accounts
payable and other current liabilities. The carrying amounts of these financial
instruments approximate fair value due to their short maturities.

 j. Stock compensation
 
  As permitted under Statement of Financial Accounting Standards ("SFAS") No.
123, "Accounting for Stock-Based Compensation," the Company has elected to
measure compensation expense as prescribed by Accounting Principles Board
Opinion No. 25, "Accounting for Stock Issued to Employees." Under that method,
the difference between the exercise price and the estimated fair value of the
shares at the date of grant is charged to compensation expense ratably over
the vesting period.
 
 k. Net loss per ordinary share
 
  Net loss per ordinary share is computed using the weighted average number of
ordinary and equivalent shares outstanding during the period. Equivalent
shares are excluded from the computation if their effect is antidilutive
except that, pursuant to the requirements of the Securities and Exchange
Commission, equivalent shares relating to options issued and ordinary shares
sold at less than the initial public offering price during the twelve-month
period prior to the initial public offering contemplated hereby are included
in the computations for all periods presented.
 
 l. New accounting pronouncements
 
  During February of 1997, the Financial Accounting Standards Board released
SFAS No. 128, Earnings per Share, which requires the disclosure of both basic
earnings per share and diluted earnings per share. The Company will be
required to adopt SFAS No. 128 effective December 31, 1997, and believes it
will not have a material impact on previously reported losses per share.
 
  Other pronouncements issued by authoritative bodies with future effective
dates are either not applicable or not material to the consolidated financial
statements of the Company.
 
3. INCOME TAXES
 
  The provision for income taxes includes United States federal, state and
foreign income taxes currently payable and deferred based on currently enacted
tax laws. Deferred income taxes are provided for the tax consequences of
differences between the financial statement and tax bases of assets and
liabilities. A valuation allowance is recognized if, based on the weight of
available evidence, it is more likely than not that some portion or all of the
deferred tax asset will not be realized.
 
  There is currently no taxation imposed by the Cayman Islands. If any form of
taxation were to be enacted, the Company has been granted exemption therefrom
to January 16, 2015. The Company's subsidiaries which do business in other
countries have not generated income and therefore are not liable for local
income taxes.
 
  Apex Corporation, a Delaware corporation, is the only entity within the
Company which is currently subject to United States federal and state income
taxes. As of June 30, 1997 and December 31, 1996, Apex Corporation had a
United States net operating loss carryforward of approximately $1,300,000
(unaudited) and $500,000, respectively. As such, no United States tax
provision is included in the accompanying financial statements. Additionally,
as of June 30, 1997 and December 31, 1996, Apex Corporation had net deferred
tax assets of approximately $500,000 (unaudited) and $200,000, respectively,
primarily as a result of operating loss carryforwards which are entirely
offset by a valuation allowance.

  As of June 30, 1997 and December 31, 1996, operating loss carryforwards
generated by ASC Bolivia amounted to approximately $9.7 million (unaudited)
and $3.4 million, respectively. Operating losses (as adjusted for inflation)
may be carried forward and deducted from taxable income indefinitely. The
deferred tax asset resulting from the operating loss carryforwards has been
entirely offset by a valuation allowance.
 
  No net deferred tax assets related to operating losses generated through
June 30, 1997 by the Company's other foreign subsidiaries have been included
in the accompanying financial statements, as all such assets have been
entirely offset by a valuation allowance.
 
4. NOTE RECEIVABLE
 
  At December 31, 1995, the note receivable represents the outstanding balance
of a $10,000,000 non-negotiable secured demand note, dated December 22, 1994,
on demand at any time, accruing interest at LIBOR, issued by Silver Holdings
LDC in consideration for 7,500 shares of the share capital (75% of the then
issued and outstanding shares) of Apex LDC. The balance at December 31, 1995
is comprised of the note receivable in the amount of $2,819,718 and accrued
interest of $66,112. The note was paid in full during 1996.

7. STOCK OPTION PLANS
 
  During 1996, options to purchase 281,250 shares of the Company's ordinary
shares were granted, exercisable at a price of $8.00 per share. Of these
options, 73,438 vested immediately. The remainder of the options vest ratably
over periods of up to four years with the first tranche vesting on the date of
grant. Unexercised options expire ten years after the date of grant.
 
The following table summarizes stock option information:

   Options outstanding at end of period.......................      281,250
   Options exercisable at end of period.......................       73,438
</TABLE>
 
  The weighted average grant-date fair value of options granted for the year
ended December 31, 1996 is $1.30. The weighted average remaining contractual
life of the options at December 31, 1996 is 11.1 years. To date, none of these
options have been exercised.
 
  Pro forma information regarding net income is required by SFAS No. 123, and
has been determined as if the Company has accounted for its employees' stock
options under the fair value method of SFAS No. 123. For purposes of
calculating the fair value of options, volatility was not considered for the
options granted in 1996 since the Company was non-public at the date of grant.
The Company currently does not foresee the payment of dividends in the near
term. The fair value for these options was estimated at the date of grant
using the Black-Scholes option pricing model with the following assumptions:

officer of Apex LDC and its subsidiaries, and an indirect shareholder. LCM is
wholly owned by an indirect shareholder of Apex LDC. This consulting
arrangement was terminated at the end of the first quarter of 1997, following
the formation of Apex Corporation. Apex Corporation provides management,
advisory and administrative services for the Company pursuant to a Management

services amounted to $423,684, $143,368 and $21,250, respectively. As of
December 31, 1996, the amount payable for such services was $11,119.
 
  Apex LDC hires both individuals and companies ("associates") to perform
services on its behalf in countries in which it has mineral interests. These
services include administrative expenses, obtaining interests in properties on
Apex LDC's behalf, and consulting services. In certain cases persons
affiliated with such associates serve as officers or directors of Apex LDC's
subsidiaries. During the periods ended December 31, 1996, 1995 and 1994, the
total amounts charged to Apex LDC by such related associates were $5,695,193,
$1,965,276 and $275,653, respectively, and are included in the statement of
operations under the applicable captions. As of December 31, 1996, the amount
payable for such services was $386,639.
 
  During the periods ended December 31, 1996, 1995 and 1994, Apex LDC paid an
associate who, until August 6, 1996, was a shareholder of certain subsidiaries
of Apex LDC $485,179, $239,647 and $14,104, respectively, in consideration for
geology services provided and disbursements made on Apex LDC's behalf. As of
December 31, 1996, the amount payable for such services was $135,517.
 
  During the year ended December 31, 1995, Apex LDC made an interest-free loan
to an indirect shareholder in the amount of $100,000. The loan was forgiven by
Apex LDC as of August 6, 1996, as partial payment for that shareholder's
remaining interest in one subsidiary and his profits interests in certain
properties owned or controlled by Apex LDC or its subsidiaries.
 
  Apex LDC received interest income on the note receivable issued by Silver
Holdings LDC, a shareholder of Apex LDC. During the periods ended December 31,
1995 and 1994, such interest income amounted to $360,937 and $15,256,
respectively.
 
  Two individuals, one of whom is an officer and indirect shareholder of Apex
LDC, the second of whom is an officer of certain of Apex LDC's subsidiaries,
are also shareholders and directors of Begeyge Minera Ltda. ("Begeyge"), with
whom the Company has a non-binding commitment to purchase the Suyatal Project
for an aggregate purchase price of $3,000,000 (see Note 10). Begeyge also
served as an associate and during the year ended December 31, 1996, total
amounts charged to Apex LDC by Begeyge were $106,691.

      these properties prior to October of 1998 for $2,000,000, less the sum of
      all prior lease payments ($12,000 per month). In addition, the Company has
      an option to acquire mining concessions for $6,000 per month until
      February 1, 1998. Upon exercise of the option, a payment of $250,000 is

      thereafter.
/6/   The commitments relating to the years 1999 to 2001 are for land taxes.
      The amounts disclosed represent the maximum possible payment. Upon
      production, the Company will pay a royalty of 5% of operating cash flow
      until the investment has been recovered, and a 15% royalty thereafter.
/7/   The lease agreement related to this property also includes payment of a

ORDINARY SHARES
 
(PAR VALUE $0.01 PER SHARE)
   
Of the [   ] shares (the "Shares") of ordinary shares, par value $0.01 per
share, (the "Ordinary Shares") of Apex Silver Mines Limited (the "Company")
offered hereby (the "Offering"), [   ] Shares are being offered initially in
the United States and Canada by the U.S. Underwriters and [   ] Shares are
being offered initially outside the United States by the Managers. See
"Underwriting". Upon completion of the Offering (assuming the over-allotment
options granted to the U.S. Underwriters and the Managers are not exercised),
the Company will own [   ] percent of the outstanding share capital of Apex
Silver Mines LDC ("Apex LDC"), the Company's principal operating subsidiary.
See "Corporate Structure". The minority shareholders of Apex LDC (the "Minority
Shareholders") are entitled to sell their shares of Apex LDC to the Company
for, at the Company's sole option, shares of the Company on a one-for-one
basis, cash, or a combination of cash and Ordinary Shares. The Company
currently expects that any future purchases by the Company of shares of Apex
LDC from the Minority Shareholders will involve only Ordinary Shares of Apex
Silver Mines Limited. Any such transactions will not affect the beneficial or
economic interest in Apex LDC attributable to shareholders of Apex Silver Mines
Limited. Currently, the Company has approximately 13,601,544 Ordinary Shares
outstanding and approximately 7,077,007 Ordinary Shares reserved for issuance
for 7,077,007 shares of Apex LDC owned by the Minority Shareholders. If all
such shares of Apex LDC were issued, the Company would have 20,678,551 Ordinary
Shares outstanding. See "Certain Transactions". AN APPLICATION WILL BE MADE TO
LIST THE SHARES FOR QUOTATION ON THE AMERICAN STOCK EXCHANGE UNDER THE TRADING
SYMBOL ["SIL"], SUBJECT TO NOTICE OF ISSUANCE.     
 
Prior to the Offering, there has been no public market for the Shares. It is
anticipated that the initial offering price will be between [$   ] and [$   ]
per share. See "Underwriting" for information relating to the factors
considered in determining the initial public offering price.
 
FOR A DISCUSSION OF CERTAIN FACTORS THAT SHOULD BE CONSIDERED BY PROSPECTIVE
INVESTORS IN PURCHASING THE SHARES OFFERED HEREBY, SEE "RISK FACTORS" ON PAGE

  The Companies Act (1995 Revision) of the Cayman Islands provides in Section
77 that:
 
  The liability of the directors, manager or the managing director of a
company may, if so provided by the memorandum of association, be unlimited.
 
  The Articles of Association of the Company provide as follows:
 
    85. (a)    Every Director (including for the purposes of this Article any
               Alternate Director appointed pursuant to the provisions of
               these Articles), Managing Director, Secretary, Assistant
               Secretary, and, at the discretion of the Board of Directors,
               other officer, consultant, employee or agent, for the time
               being and from time to time of the Company and the personal
               representatives of the same shall be indemnified and secured
               harmless out of the assets and funds of the Company against all
               actions, proceedings, costs, charges, expenses, losses, damages
               or liabilities incurred or sustained by him in or about the
               conduct of the Company's business or affairs or in the
               execution or discharge of his duties, powers, authorities or
               discretions, including without prejudice to the generality of
               the foregoing, any costs, expenses, losses or liabilities
               incurred by him in defending (whether successfully or
               otherwise) any civil proceedings concerning the Company or its
               affairs in any court whether in the Cayman Islands or elsewhere
               provided, that no indemnification shall be available in the
               case of wilful default or fraud.
 
        (b)    No such Director, Alternate Director, Managing Director, agent,
               Secretary, Assistant Secretary or other officer of the Company
               shall be liable (i) for the acts, receipts, neglects, defaults
               or omissions of any other such director or officer or agent of
               the Company or (ii) by reason of his having joined in any
               receipt for money not received by him personally or (iii) for
               any loss on account of defect of title to any property of the
               Company or (iv) on account of the insufficiency of any security
               in or upon which any money of the Company shall be invested or
               (v) for any loss incurred through any bank, broker or other
               agent or (vi) for any loss occasioned by any negligence,
               default, breach of duty, breach of trust, error of
 
                                     II-1
<PAGE>
 
               judgment or oversight on his part or (vii) for any loss, damage
               or misfortune whatsoever which may happen in or arise from the
               execution or discharge of the duties, powers authorities, or
               discretions of his office or in relation thereto, unless the
               same shall happen through his own dishonesty.
 
        (c)    The Board of Directors may authorize the Company to purchase
               and maintain insurance on behalf of any person described in
               Section 83(a), against any liability asserted against him and
               incurred by him in any such capacity, or arising out of his
               status as such, whether or not the Company would have the power
               to indemnify him against such liability under the provisions of
               this Section 83.
 
  To the extent that it is permitted to do so by these provisions, the Company
intends to give an indemnity to each of its directors and to arrange for the
liabilities under these indemnities to be covered.

    2. Effective as of August 6, 1996, the Company issued (i) 25,000 Ordinary

ITEM 17. UNDERTAKINGS.
 
  Insofar as indemnification for liabilities arising under the Securities Act
of 1933 may be permitted to directors, officers and controlling persons of the
registrant pursuant to the provisions described in Item 14 of this
registration statement or otherwise may be permitted, the registrant has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act
and is, therefore, unenforceable. In the event that a claim for
indemnification against such liabilities (other than the payment by the
registrant of expenses incurred or paid by a director, officer or controlling
person of the registrant in the successful defense of any action, suit or
proceeding) is asserted by such director, officer or controlling person in
connection with the securities being registered, the registrant will, unless
in the opinion of its counsel the matter has been settled by controlling
precedent, submit to a court of appropriate jurisdiction the question whether
such indemnification by it is against public policy as expressed in the
Securities Act and will be governed by the final adjudication of such issue.
 
 
  The undersigned registrant hereby undertakes that:
 
    (1) For purposes of determining any liability under the Securities Act of
  1933, the information omitted from the form of prospectus filed as part of
  this registration statement in reliance upon Rule 430A and contained in a
  form of prospectus filed by the registrant pursuant to Rule 424(b)(1) or
  (4) or 497(h) under the Securities Act shall be deemed to be part of this
  registration statement as of the time it was declared effective.
 
    (2) For the purpose of determining any liability under the Securities Act
  of 1933, each post-effective amendment that contains a form of prospectus
  shall be deemed to be a new registration statement relating to the
  securities offered therein, and the offering of such securities at that
  time shall be deemed to be the initial bona fide offering thereof.
 
    (3) The undersigned registrant hereby undertakes to provide the
  underwriters at the closing specified in the underwriting agreements
  certificates in such denominations and registered in such names as required
  by the underwriters to permit prompt delivery to each purchaser.

     Notice") to the Company and the other Original Investors.  The Offer Notice

     such Shares or Sub Shares not elected to be purchased by the end of such
     10-day period shall be reoffered for an additional ten (10) day period by
     the Transferring OI Holder on a pro rata basis to the Original Investors
     who have elected to purchase their Investor Pro Rata Share.  Each Original
     Holder's "Investor Pro Rata Share" shall be based upon such Original

     the Original Investors shall be consummated as soon as practical after the
     delivery of the final Election Notice, but in any event within 15 days
     after the delivery of the final Election Notice. In the event that the
     Original Investors do not elect to purchase all of the OI Transfer Shares,
     the Transferring OI Holder may, within 90 days after the expiration of the
     Election Period, transfer such remaining OI Transfer Shares to one or more
     third parties at a price no less than the price per share specified in the
     Offer Notice for such class and on other terms no more materially favorable
     to the transferees thereof than offered to the Original Investors in the
     Offer Notice. Any OI Transfer Shares not transferred within such 90-day
     period shall be reoffered to the Original Investors under this Section 3(c)
     prior to any subsequent Transfer pursuant to the terms of this Section. The
     purchase price specified in any Offer Notice shall be payable solely in
     cash at the closing of the transaction or in installments over time, and no
     Shares may be pledged without the prior written consent of the
     Shareholders, which consent may be withheld in their sole discretion.

          (d) Other Restrictions.  (i) After the Restricted Period, Shares or
              ------------------

or Rule 144A of the Securities Act (or any similar rule or rules then in force)
if such rule is available, and (C) subject to the conditions specified in
Section 3(d)(ii) below, any other legally available means of transfer.

              (ii) In connection with the transfer of any Shares or Sub Shares
     (other than a transfer described in Section 3(d)(i) (A) or (B) above), the
     holder thereof shall deliver written notice to the Company describing in
     reasonable detail the transfer or proposed transfer, together with an
     opinion of counsel which (to the Company's reason able satisfaction) is
     knowledgeable in securities law matters to the effect that such transfer of
     Shares or Sub Shares may be effected without registration of such Shares or
     Sub Shares under the Securities Act.  In addition, if the holder of the
     Shares or Sub Shares delivers to the Company an opinion of counsel that no
     subsequent transfer of such Shares or Sub Shares shall require registration
     under the Securities Act, the Company shall promptly upon such contemplated
     transfer deliver new certificates for such Shares or Sub Shares which do
     not bear the Securities Act legend set forth in Section 4.  If the Company
     is not required to deliver new certificates not bearing such legend in
     exchange for such Shares or Sub Shares, the holder thereof shall not
     transfer the same until the prospective transferee has confirmed to the
     Company in writing its agreement to be bound by the conditions contained in
     this Section and Section 4.

          (e) Permitted Transfers.  The restrictions set forth in this Section 3

shall not apply to (i) any Transfer of Shares by any Shareholder among its
Affiliates, (ii) a Transfer of Shares by any Shareholder pursuant to the laws of
descent and distribution or among such Share holder's Family Group, (iii) any
Transfer from a Shareholder to another Shareholder, provided that the provisions
                                                    --------                    
of this Agreement will continue to be applicable to the Shares after any
Transfer pursuant to clauses (i), (ii) and (iii) above and the transferees of
such Shares shall agree in writing to be bound by the provisions of this
Agreement.  Upon the Transfer of Shares pursuant to clauses (i), (ii) and (iii)
of the previous sentence, each transferee will deliver a

                                      -5-

written notice to the Company, which notice will disclose in reasonable detail
the identity of such transferee.

             -----------------

outstanding Shares), the Company shall first offer to sell to each Shareholder a
portion of such Shares or other securities equal to the percentage of Shares
and, for the purposes hereof, Sub Shares held by such Shareholder at the time of
such issuance.

             (ii) In order to exercise its purchase rights hereunder, each
Shareholder must within 20 days after receipt of written notice from the Company
describing in reasonable detail the Shares or securities being offered, the
purchase price thereof, the payment terms and such Shareholder's pro rata
percentage allotment, deliver a written notice to the Company describing its
election hereunder.  Any Shares not elected to be purchased by the end of such
20-day period shall be reoffered for an additional 10-day period by the Company
on a pro rata basis to the Shareholders who elected to purchase the entire
allotment of Shares originally offered to such Shareholders.

             (iii)  Upon the expiration of the offering periods described above,
the Company shall be entitled to sell such Shares or securities which the
Shareholders have not elected to purchase during the 180 days following such
expiration on terms and conditions no more favorable to the purchasers thereof
than those offered to the Shareholders.  Any Shares or securities offered or
sold by the Company to any Person after such 180-day period must be reoffered to
the Shareholders pursuant to the terms of this Section.

Company's assets determined on a consolidated basis, or a sale of all or
substantially all of the Company's outstanding capital stock (whether by merger,
recapitalization, consolidation, reorganization, combination or otherwise) to
any independent third party or group of independent third parties is approved by
the Company's Board (any such Company Sale approved by the Board constituting an
"Approved Sale"), each Shareholder will consent to and raise no objections to
 -------------                                                               
such Approved Sale.

                                      -7-
<PAGE>
 
          (b) In connection with any such Approved Sale, (i) if the Approved

waive any dissenters rights, appraisal rights or similar rights in connection
with such merger or consolidation, (B) a sale of stock, each Shareholder shall
agree to sell all of his Shares, or rights to acquire Shares, on the terms and
conditions so approved, or (C) as a sale of assets, each Shareholder shall vote
in favor of such sale and any subsequent liquidation of the Company or other
distribution of the proceeds therefrom, (ii) each Shareholder shall take all
necessary or desirable actions in connection with the consummation of the
Approved Sale reasonably requested by the Company and (iii) each Shareholder
shall be obligated to join on a pro rata basis (based on the share of the
aggregate proceeds paid in such Approved Sale) in any indemnification or other
obligations that the Company agrees to provide in connection with such Approved
Sale other than any such obligations that relate specifically to the Company or
to a particular Shareholder such as indemnification with respect to
representations and warranties given by a Shareholder regarding such
Shareholder's title to and ownership of Shares; provided that no Shareholder
                                                --------                    
shall be obligated in connection with such Approved Sale to agree to indemnify
or hold harmless the prospective transferee(s) with respect to an amount in
excess of the net cash proceeds paid to such holder in connection with such
Approved Sale.

          (c) The obligations of the Shareholders with respect to an Approved
Sale are subject to the satisfaction of the following conditions: (i) upon the
consummation of the Approved Sale, each Shareholder will receive the same form
of consideration and the same portion of the aggregate consideration that such
Shareholders would have received if such aggregate consideration had been
distributed by the Company in complete liquidation pursuant to the rights and
preferences set forth in the Company's Memorandum and Articles of Association as
in effect immediately prior to such Approved Sale and (ii) each holder of then
currently exercisable rights to acquire Shares will be given an opportunity to
exercise such rights prior to the consummation of the Approved Sale and
participate in such sale as Shareholders.

          (d) If the Company or any one or more Shareholders enter into any
negotiation or transaction for which Rule 506 (or any similar rule then in
effect) promulgated by the Securities Exchange Commission may be available with
respect to such negotiation or transaction (including a merger, consolidation or
other reorganization), the Shareholders will, at the request of the Company,
appoint a purchaser representative (as such term is defined in Rule 501)
reasonably acceptable to the Company.  If any Shareholder appoints a purchaser
representative designated by the Company, the Company will pay the fees of such
purchaser representative, but if any Shareholder declines to appoint the
purchaser representative designated by the Company such holder will appoint
another purchaser representative, and such Shareholder will be responsible for
the fees of the purchaser representative so appointed.

          (e) Shareholders will bear their pro rata share (based upon the number
of Shares (including the aggregate number of Shares which would be issued in the
event the Company purchased all outstanding Sub Shares for Shares) which would
be sold) of the costs of any sale of Shares pursuant to an Approved Sale to the
extent such costs are incurred for the benefit of all Shareholders and are not
otherwise paid by the Company or the acquiring party.  For purposes of this
section 8(e), costs incurred in exercising reasonable efforts to take all
necessary actions in connection with the consummation of an Approved Sale in
accordance with

                                      -8-
<PAGE>
 
Section 8(a) shall be deemed to be for the benefit of all Shareholders.  Costs
incurred by Shareholders on their own behalf will not be considered costs of the
transaction hereunder.

          (f) The provisions of this Section 8 will terminate upon the
consummation of a Public Offering.

          10. COMPANY REPRESENTATIONS.  The Company hereby represents and
              -----------------------

Company or the ability of the Company to perform its obligations under this
Agreement.

          (b) The Company has all requisite corporate power and authority to

binding obligation of the Company, enforceable against it in accordance with its
terms.

          (d) There is no action suit, investigation or proceeding of or before

jurisdiction, such invalidity, illegality or unenforceability shall not affect
any other provision or the effectiveness or validity of any provision in any
other jurisdiction, and this Agreement shall be reformed, construed and enforced

Apex Corporation pursuant to this Agreement, Apex Corporation shall receive a
fee in an amount equal to the direct and indirect costs incurred by Apex
Corporation in providing such services to the Apex Group (including, without
limitation, personnel costs, travel and expenses for fees and disbursements of
third parties and all overhead expenses), plus ten percent (10%) of such costs
(such fee, the "Service Fee").
                -----------   

                                      -3-
<PAGE>
 
          (b) Unless paragraph 5(c) applies, the Service Fee shall be allocated
to each entity comprising the Apex Group in the following manner:  time devoted
to any specific Apex Group entity and time devoted to the Apex Group as a whole.

          (c) The parties hereby agree that if a method of allocating and
apportioning the Service Fee among the members of the Apex Group exists that is
more appropriate than the method set forth in paragraph 5(b) above, such method
shall be implemented and this Agreement shall be modified accordingly.  Factors
to be considered in establishing a different method of allocation and
apportionment shall include, total expenses, asset size, sales, payroll and the
level of expertise of each Apex Group member.

          (d) Apex Corporation shall establish and maintain a system that
identifies all costs related to the services provided under this Agreement.  The
Apex Group or a mutually agreed upon certified public accountant shall have

month shall be the prorated portion thereof for the actual number of days.

          (f) In the event that Apex Corporation needs an advance with respect
to the Service Fee in order to render the services set forth herein to the Apex
Group, such advance shall be provided to Apex Corporation upon the consent of
the board of directors of Apex Limited.  Such advance shall be credit against
the future monthly Service Fee payable by Apex LDC (on behalf of any and all
relevant Apex Group entities) in a manner mutually agreeable by the parties.

          (g) The parties hereto agree that the documentation as required
pursuant to Sections 6038A and 6662(e) of the Code shall be prepared as soon as
practicable and be maintained in order to establish and support the Service Fee.

     6.   Non-Exclusivity.  Nothing in this Agreement shall be construed to
          ---------------                                                  
restrict Apex Corporation's ability to provide services to parties other than
members of the Apex Group, provided that if any such services rendered to a
party other than a member of the Apex Group are similar to the services rendered
to members of the Apex Group under this Agreement, the provision of such
services shall require the prior consent of the board of directors of Apex
Limited.

     7.   Exculpation and Indemnification of Apex Corporation.  (a)  To the
          ---------------------------------------------------              
fullest extent permitted by law, none of Apex Corporation or its officers,
directors or employees (each an "Exculpated Party") shall be liable to the Apex
                                 ----------------                              
Group for (i) any act or omission taken or suffered by such Exculpated Party in
connection with the conduct of the business of the Apex Group in connection with
this Agreement, (ii) the rendering of advice to the Apex Group, (iii) the
provision of other services by such Exculpated Party in accordance herewith,
(iv) any

                                      -4-
<PAGE>
 
action or omission taken or suffered by the Apex Group;  provided, that such
limitation from any liability shall not apply to any Exculpated Party that is
not a natural person to the extent of any such Exculpated Party's gross
negligence, willful misconduct or bad faith (or the gross negligence, willful
misconduct or bad faith of any shareholder, member, officer, director or
employee of such Exculpated Party) in complying with the material terms of this
Agreement.  To the extent that, at law or in equity, any Exculpated Party has
duties (including fiduciary duties) and liabilities relating thereto to the Apex
Group, such Exculpated Party acting under this Agreement shall not be liable to
the Apex Group for its good faith reliance on the provisions of this Agreement.
The provisions of this Agreement, to the extent that they restrict the duties
and liabilities of an Exculpated Party otherwise existing at law or in equity,
are agreed by the parties hereto to modify to that extent such other duties and
liabilities of such Exculpated Party.

          (b) An Exculpated Party may consult with legal counsel, accountants or
professional advisors selected by it with reasonable care, and any act or
omission taken or suffered by it on behalf of the Apex Group in furtherance of
the business of the Apex Group in good faith in reliance on and in accordance
with the advice of such counsel, accountants or professional advisors shall be
full justification for the act or omission, and the Exculpated Party shall be
fully protected in so acting or omitting to act provided such counsel,
accountants or professional advisors were selected with reasonable care.

          (c) Subject to Section 7(e) hereof, to the fullest extent permitted by
law, Apex LDC shall indemnify and save harmless Apex Corporation, and its
officers, directors or employees (each, an "Indemnified Party") from and against
                                            -----------------                   
any and all claims, liabilities, damages, losses, costs and expenses (including
amounts paid in satisfaction of judgments, in compromises and settlements, as
fines and penalties and legal or other costs and expenses of investigating or
defending against any claim or alleged claim but excluding any liabilities for
taxes of any Indemnified Party) of any nature whatsoever, known or unknown,
liquidated or unliquidated, that are incurred by such Indemnified Party and
arise out of or in connection with the business of the Apex Group or the
performance by such Indemnified Party of its responsibilities hereunder
(including, without limitation, those that arise out of or in connection with
the employment by Apex Corporation of advisors, agents or other third parties to
assist Apex Corporation in the performance of its duties pursuant to this
Agreement) (each of the foregoing, a "Claim");  provided, that an Indemnified
                                      -----                                  
Party shall not be entitled to indemnification hereunder to the extent such
Claim arises from such Indemnified Party's gross negligence, willful misconduct
or bad faith with respect to material terms of this Agreement.  The termination
of any proceeding by settlement, judgment, order or upon a plea of nolo
contendere or its equivalent shall not, of itself, create a presumption that an
Indemnified Party was grossly negligent or engaged in willful misconduct or bad
faith.  Any Person entitled to indemnification from Apex LDC hereunder shall
obtain the written consent of Apex LDC (which consent shall not be unreasonably
withheld) prior to entering into any agreement or settlement which would result
in an obligation of the Apex Group to indemnify such Person; provided, that any
Person entitled to indemnification hereunder may enter into an agreement or
settlement without the written consent of Apex LDC on the condition that the
right of such Indemnified Party to indemnification by Apex LDC is irrevocably
waived.

          (d) Expenses incurred by an Indemnified Party in defense or settlement
of any Claim that may be subject to a right of indemnification hereunder may be
advanced by

                                      -5-
<PAGE>
 
Apex prior to the final disposition thereof upon receipt of an undertaking by or
on behalf of the Indemnified Party to repay such amount to the extent that it
shall be determined ultimately that such Indemnified Party is not entitled to be
indemnified hereunder. The right of any Indemnified Party to the indemnification
provided herein shall be cumulative of, and in addition to, any and all rights
to which such Indemnified Party may otherwise be entitled by contract or as a
matter of law or equity and shall be extended to such Indemnified Party's
successors, assigns and legal representatives.

          (e) Promptly after receipt by an Indemnified Party of notice of the
commencement of any action or proceeding or threatened action or proceeding in
connection with any Claim referred to in Section 7(c), such Indemnified Party
shall give written notice thereof to the Apex Group; provided, that the failure
of an Indemnified Party to give such notice shall not relieve Apex LDC of its
obligations pursuant to Section 7(c) hereof, except to the extent that the Apex
Group is actually prejudiced by such failure to give notice.

          (f) In case any action or proceeding is commenced against any
Indemnified Party which may be subject to indemnification pursuant to this
Section 7, the Apex Group shall have the right to assume the defense thereof,
with counsel reasonably satisfactory to such Indemnified Party.  After notice
from Apex LDC to such Indemnified Party of Apex LDC's election to assume the
defense thereof, Apex LDC will be liable for the expenses subsequently incurred
by such Indemnified Party in connection with the defense thereof.  Apex LDC will
not consent to the entry of any judgment or enter into any settlement which does
not include as an unconditional term the giving to such Indemnified Party a
release from all liability in respect of such Claim.

          (g) Any person who is not a party to this Agreement may be required,
prior to being paid any amount under this Section 7, to agree to the provisions
of this Section 7 applicable to Indemnified Parties.

          (h) Any claims which may be the subject of a right of indemnification
pursuant to this Section 7 shall be subject to verification by an independent
accountant acceptable both to the party giving and the party receiving
indemnification.

     8.   Term and Termination.  (a)  This Agreement shall become effective as
          --------------------                                                
of October 22, 1996 and shall remain in full force and effect until the date of
termination or removal pursuant to subsections 8(b) and 8(c) below.

     (b)  The Apex Group may terminate this Agreement or remove Apex
Corporation at any time upon 30 days' written notice to Apex Corporation
delivered in accordance with the provisions of Section 11 hereof.

     (c)  Apex Corporation may terminate this Agreement at any time by
delivering to Apex LDC (with a copy to Apex Limited's Board of Directors) a
notice to that effect (the "Resignation Notice").  Apex Corporation's
                            ------------------                       
resignation shall be effective on the 90th day following the receipt of the
Resignation Notice by Apex LDC (the "Resignation Date").
                                     ----------------   

                                      -6-
<PAGE>
 
       (d)  If the Resignation Date is a date other than the end of a calendar
month, at the start of the calendar month in which the Resignation Date will
occur, Apex LDC shall pay to Apex Corporation the amount of its Services Fee
allocable to that portion of the calendar month which is prior to the
Resignation Date.

       (e)  The provisions of Section 7 shall survive the termination of this
Management Services Agreement.

       9.   Independent Contractor Status.    This Agreement is intended to
            -----------------------------                                  
create, and creates, a contractual relationship for services to be rendered by
Apex Corporation acting in the ordinary course of its business as independent
contractor and is not intended to create, and does not create, a partnership,
joint venture or any like relationship among the parties hereto (or any other
parties).

       10.  Arbitration.  Any dispute or disagreement which may arise under, or
            -----------                                                        
as a result of, or in any way relate to, the interpretation, construction or
application of this Agreement shall be determined by binding arbitration.  The
parties may agree to submit the matter to a single arbitrator or to several
arbitrators, may require that arbitrators possess special qualifications or
expertise or may agree to submit a matter to a mutually acceptable firm of
experts for decision.  In the event the parties shall fail to thus agree upon
terms of arbitration within twenty (20) days from the first written demand for
arbitration, then such disputed matter shall be settled by arbitration under the
Rules of the American Arbitration Association, by three arbitrators appointed in
accordance with such Rules.  Such arbitration shall be held in New York, New
York.  Once a matter has been submitted to arbitration pursuant to this section,
the decision of the arbitrators reached and promulgated as a result thereof
shall be final and binding upon all parties.  The cost of arbitration shall be
shared equally by Apex Limited and the Consultant and each party shall pay the
expenses of its attorneys, except that the arbitrators shall be entitled to
award the costs of arbitration, attorneys' and accountants' fees, as well as
costs, to the party that they determine to be the prevailing party in any such
arbitration.

Agreement, any voting securities of the Company issued in respect thereof by

blank or properly assigned, by the acceptance or holding thereof, shall be
deemed conclusively for all purposes to have assented to this Agreement and to
all of its terms, conditions and provisions and shall be bound thereby with the
same force and effect as if such holder or bearer had executed this Agreement.
Without limiting the foregoing, this Agreement shall be binding upon and inure
to the benefit of each of the parties hereto and their respective heirs,

other covenant or condition of this Agreement.

     WHEREAS, the Beneficiary is the holder of Two Million Seven Hundred Thirty-
Nine Thousand One Hundred Fifty-Three and Ninety-Three One-Hundredths
(2,739,153.93) ordinary shares, par value US $0.01 per share (each a "Share" and
collectively the "Shares") of Apex Silver Mines Limited, a Cayman Islands
corporation (the "Company"); and

     WHEREAS, in order to vest in the Trustee the sole right to vote the Shares
and all investment authority and power with respect to the Shares, the
Beneficiary is willing to deposit the Shares owned by it with the Trustee under
this Agreement for the period commencing on the date hereof and ending upon the
termination of this Agreement in accordance with its terms.

     NOW, THEREFORE, the parties hereto agree as follows:

     1.  Delivery to Trustee of Certificates for Shares.   Simultaneously with
the execution and delivery of this Agreement, the Beneficiary shall deliver to
the Trustee certificates representing an aggregate of Two Million Seven Hundred
Thirty-Nine Thousand One Hundred Fifty-Three and Ninety-Three One-Hundredths
(2,739,153.93) Shares, representing all of the Shares held by the Beneficiary,
endorsed in blank or accompanied by duly completed instruments of share transfer
executed by the Beneficiary.  Immediately subsequent to the execution and
delivery of this Agreement and such instruments of share transfer, the Trustee
shall deliver a copy of this Agreement to the Company, shall surrender to the
Company said certificates and instruments of share transfer, and the Trustee and
Beneficiary shall take all further necessary or appropriate actions to cause the
Directors to enter the name of the Trustee in the register of Members in respect

     2.  Delivery to Trustee of Certificates for Additional Shares.  Any and all
certificates for additional shares of the Company issued to the Beneficiary
while it is the Beneficiary under this Agreement shall be in like manner
endorsed and delivered to the Trustee together with a duly completed and
executed form of share transfer to be held by him subject to the terms and
conditions hereof.  All such additional shares shall be deemed to be "Shares"
for all purposes of this Agreement.

     3.  Delivery of Trustee's Certificates.  Upon the delivery to the Trustee
of the certificates and forms of share transfer referred to in paragraph 1
hereof, the Trustee shall deliver to the Beneficiary a certificate (the
"Trustee's Certificate") for the number of Shares delivered to the Trustee by
the Beneficiary, substantially in the form hereinafter set forth.  Upon each
receipt of certificates for additional shares issued to a Beneficiary, the
Trustee shall deliver to such Beneficiary a Trustee's Certificate for the number
of shares so deposited, substantially in the form hereinafter set forth.

     The Trustee's Certificate (the terms and provisions of which are a part of
this Agreement) shall be substantially in the following form:


                             TRUSTEE'S CERTIFICATE

          This is to certify that the undersigned Trustee has received a
     certificate or certificates issued in the name of Thomas Kaplan, Trustee,
     evidencing the ownership of ___ shares of a nominal or par value of US
     $0.01 each of Apex Silver Mines Limited, a Cayman Islands corporation (the
     "Shares"), and that the Shares are held subject to all the terms and
     conditions of that certain Agreement (the "Voting Trust Agreement"), dated
     as of August 27, 1997, by and between Argentum LLC and Thomas Kaplan, as
     Trustee.  During the term of the Voting Trust Agreement, the Trustee shall,
     as provided in the Voting Trust Agreement, possess and be entitled to
     exercise the right to vote and otherwise represent all of the Shares for
     all purposes, and to exercise all investment authority and power with
     respect to all of the Shares for all purposes, it being agreed that no
     voting right and no investment authority or power shall pass to the holder
     hereof by virtue of the ownership of this Certificate.

          This Certificate is assignable with the right to issuance of a new
     certificate of like tenor only upon the surrender to the Trustee of this
     certificate properly endorsed.  Upon the termination of the Voting Trust

                                       2
<PAGE>
 
     Agreement, this certificate shall be surrendered to the Trustee by the
     holder hereof upon delivery to the holder hereof of a certificate
     representing the Shares not sold or otherwise disposed of by the Trustee
     pursuant to the Voting Trust Agreement.

          IN WITNESS WHEREOF, the undersigned has executed this Certificate this
     ____ day of _______________, ____.

                                    ______________________
                                    Thomas Kaplan, Trustee

     Each Trustee's Certificate may be transferred by endorsement by the person
to whom issued, or by his, her or its attorney-in-fact, or by the administrator
or executor of his, her or its estate, by delivery of such Trustee's Certificate
so endorsed to the Trustee; but such transfer shall not be evidence to or be
binding upon the Trustee until such Trustee's Certificate is surrendered to the
Trustee and the transfer is entered upon the "Trustee's Certificate Book", which
shall be kept by the Trustee to show the names of the parties by whom and to
whom transferred, the numbers of the certificates, the number of shares and the
date of transfer.  No new Trustee's Certificate shall be issued until the
Trustee's Certificate for the shares represented thereby shall have been
surrendered to and cancelled by the Trustee, and the Trustee shall preserve the
certificates so cancelled as vouchers.  In case any Trustee's Certificate shall
be claimed to be lost or destroyed, a new Trustee's Certificate may be issued in
lieu thereof, upon such proof of loss as may be required by the Trustee.


     4.   Voting and Investment Authority and Power of Trustee.

shareholders of the Company and may vote for, do or assent or consent to and
shall have all the powers, rights and privileges of a shareholder of the
Company.

          b.   The Trustee may vote in person or by proxy, and a proxy in
writing signed by the Trustee shall be sufficient authority to the person named
therein to vote all the Shares held by the Trustee hereunder at any meeting,
regular or special, of the shareholder of the Company.

          c.   The Trustee shall have complete investment authority and power
with respect to the Shares held by the Trustee hereunder, including, without
limitation, the authority and power to sell or otherwise dispose of any or all
of the Shares on such terms and subject to such conditions, as the Trustee in
his sole discretion

                                       3
<PAGE>
 
shall deem appropriate.  The Beneficiary and each holder of Trustee's
Certificates hereby appoints the Trustee as his, her or its attorney-in-fact to
execute any documents or instruments necessary (in the determination of the
Trustee) to effect such sale or disposition.  Without limiting the foregoing,
each holder of Trustee's Certificates hereby agrees, following written
notification from the Trustee of any such contemplated sale or other disposition
of Shares, to surrender to the Trustee at the time and place indicated in such
notice, his, her or its Trustee's Certificates.  The Trustee, promptly following
the closing of any such sale or other disposition of Shares, shall issue and

interest in the net proceeds of any such sale or other disposition of Shares

Trustee's Certificates, and such payment of such net proceeds, this Agreement
shall terminate as to the shares so sold or otherwise disposed of.

     5.   Distribution of Cash Dividends.

     (a)  The Trustee shall distribute directly any cash dividends or
distributions declared and paid on the Shares deposited hereunder (other than
dividends or distributions made in the form of voting securities of the Company)
to the holders of Trustee's Certificates in proportion to their respective
interests therein as shown on the books of the Trustee, such distribution to be
equivalent to the dividends or distribution which each respective holder would
have been entitled to receive had the Shares not been deposited hereunder.

Agreement, any voting securities of the Company issued in respect thereof by
reason of any dividend, distribution, capital reorganization, stock split,
combination or the like and shall issue and deliver Trustee's Certificates
therefor to the holders of the Trustee's Certificates in proportion to their
respective interests therein as shown on the books of the Trustee.
 
     6.   Term of Agreement.  This Agreement and the trust hereby created shall
terminate on December 31, 1997.  Until termination in accordance with the terms
of this Agreement, neither this Agreement nor the trust hereby created shall be
revocable or amendable, in whole or in part.

any error of judgment or mistake of fact or law, or for any act or omission
undertaken in good faith in connection with his powers and duties under this

Trustee shall not be

liable for acts or omissions of any employee or agent of the Company.  The
Trustee shall not be liable for acting in reliance on any notice, request,

opinion of legal or other counsel shall be binding and conclusive on the parties
to this Agreement.
