        Statements contained in the annual report that are not historical facts
are forward-looking statements as that term is defined in the Private Securities
Litigation Reform Act of 1995. Such forward-looking statements are subject to
risks and uncertainties, which could cause actual results to differ materially
from estimated results. Such risks and uncertainties are detailed in filings
with the Securities and Exchange Commission, including, without limitation, in
Item 1. "BUSINESS", Item 2. "PROPERTIES" and Item 7. "MANAGEMENT'S DISCUSSION
AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS" below.

ITEM 1. BUSINESS

        Azco Mining Inc. ("AZCO" or the "Company") is a U.S. mining company with
a general business strategy to acquire and develop mineral properties amenable
to low cost production. The Company is currently focused on producing high
quality Muscovite Mica from its 100% owned Black Canyon Mica project located in
Arizona. The Company, with its 30% interest, has established a strategic
partnership with Phelps Dodge Corporation on the Piedras Verdes copper project
located in Sonora, Mexico. The business strategy on large exploration projects
has been focused on establishing partnerships with major companies. This
strategy generally reduces financial risk and offers the opportunity to
participate in major mineral projects.

        Prior to the sale of the majority of its copper assets the Company was
dedicated to the development and production of low-cost copper utilizing solvent
extraction-electrowinning or the SX-EW process. AZCO's principal mineral
property was the Sanchez porphyry copper project ("Sanchez" or "Sanchez
Project") located about 10 miles northeast of the City of Safford in
southeastern Arizona. The Company also had interests in two other porphyry
copper properties, the Piedras Verdes and Suaqui Verde properties located in
Sonora State, Mexico. On July 27, 1995 the Board of Directors of AZCO (the
"Board") signed definitive agreements with Phelps Dodge Corporation ("Phelps
Dodge" or "PDC") to sell a substantial portion of the Company's copper assets.
AZCO's shareholders approved the sale of 100% of the Sanchez and 70% of the
Piedras Verdes project for gross consideration of $40 million.

        A predecessor of AZCO was incorporated on July 13, 1988 under the laws
of Colorado to acquire the mining rights to the Sanchez, as well as certain
other mineral properties. On August 27, 1991, the predecessor was merged into
AZCO, a newly incorporated Delaware corporation. In October 1991, AZCO acquired
all of the shares of Filton Enterprises Limited, a Gibraltar corporation
("Filton"), in return for the issuance of 3,650,000 common shares. At that time
Filton owned rights in two mining properties located in Mexico, the Suaqui Verde
project in southeastern Sonora and the Piedras Verdes project in southern
Sonora. Filton was dissolved effective February 14, 1994 with its Mexican
interests being distributed to the Company.

        On July 31, 1992 AZCO merged with AZCO Mining Inc., a Wyoming
corporation ("AZCO (Wyoming)"), with AZCO being the survivor of the merger (the
"Merger"). At the time of the completion of the Merger AZCO (Wyoming) had
3,946,550 shares issued and outstanding and the Company had 12,633,822 common
shares issued and outstanding. One common share of the Company was issued in
exchange for each


                                       2
<PAGE>   3

share of AZCO (Wyoming) in connection with the Merger. AZCO (Wyoming) was
formerly a British Columbia corporation, which was incorporated under the laws
of the Province of British Columbia on August 20, 1981 under the name 241145
B.C. Ltd. 241145 B.C. Ltd. changed its name to Canarex Resources Inc. on June
22, 1983, to International Baron Resources Ltd. on January 25, 1988 and finally
to AZCO Mining Inc. on February 20, 1992. AZCO (Wyoming) was continued under the
laws of Wyoming effective May 13, 1992 prior to merging with AZCO.

SIGNIFICANT DEVELOPMENTS IN FISCAL 1999 AND SUBSEQUENT EVENTS

        On March 9, 1999 the Company completed the acquisition of Arizona Mica
Properties, Inc., an Arizona corporation ("Arizona Mica"), which owned the
rights to develop 43 unpatented lode-mining claims located in Yavapai County,
Arizona. This acquisition was accomplished through the merger of Arizona Mica
with and into the Company's wholly owned subsidiary, Sanchez Mining Inc., a
Delaware corporation ("Sanchez"), with Sanchez being the surviving corporation
in the merger. Sanchez has subsequently changed its name to AZCO Mica, Inc. In
connection with the merger, the Company issued an aggregate of 4,500,000 shares
(the "Shares") of its common stock to the three shareholders of Arizona Mica,
Messrs. Lawrence G. Olson, John O. Rud and Floyd R. Bleak, with each such
shareholder receiving 1,500,000 shares of the Company's common stock. The Shares
were issued as "restricted securities", as that term is defined in Rule 144
promulgated under the United States Securities Act of 1933, as amended (the
"Act"), and the certificates representing the Shares bear a restrictive legend
permitting transfer only pursuant to registration or applicable exemption under
the Act.

        The Company undertook a 3-month due diligence period, which included
confirmation drilling, a marketing study and environmental and legal audits. The
price of the transaction was determined at arms length with the principals of
Arizona Mica.

        In addition to the 43 mining claims the Company also acquired a pilot
mica processing facility that Arizona Mica was developing in Glendale, Arizona.
The Company is currently developing further this processing facility.

                                       ***

        On June 18, 1998 the Company entered into an agreement with Minera
Cortez Resources Ltd. ("Cortez") whereby the Company was granted a right of
first refusal for a period of five years to acquire all or any property
interests that Cortez desired to either joint venture, option or dispose of. In
consideration, therefore, the Company has subscribed for 200,000 common shares
of Cortez at Cdn. $.25 per share. The Company was also granted a right of first
refusal for the same period to provide up to 100% of any private or public
equity or debt financing that Cortez proposes to obtain, on similar terms, as
any third party is willing to provide.

        On July 21, 1998 the Company entered into an option agreement with
Cortez whereby the Company was granted an option to earn up to a 70% interest in
the La Adelita property located in Sonora, Mexico, under the following terms:

1. by subscribing to 100,000 common shares of Cortez at Cdn. $0.25 per share;


                                       3
<PAGE>   4

2. by making option payments and paying finders' fees on behalf of Cortez
   totaling $165,000 over the next five years; and

3. by incurring exploration expenditures on the property totaling $500,000 over
   the next three years.

        On June 10, 1999 the Company acquired a 100% interest in the Silverado
property, which surrounds the Adelita property, from Cortez for $20,000 and
30,000 of the Company's shares.

                                       ***

        On May 9, 1996 the Company signed an agreement with West Africa Gold &
Exploration Ltd., Eagle River International Limited ("Eagle") and Lion Mining
Finance Limited ("Lion") that provided for the establishment of a joint venture
holding company, Sanou Mining Corporation ("Sanou"). Sanou is the sole
beneficial owner of a Malian subsidiary headquartered in Bamako and called
Western African Gold and Exploration Company S.A. ("WAG"), which has a 100%
working interest in the Medinandi and Dandoko concessions located in the Kenieba
Gold Mining District of western Mali. Eagle, the original principal concession
owner through a Malian subsidiary, has caused that subsidiary to convey the
concessions to Wag.

        Effective August 9, 1996 Wag entered into a debenture agreement with
AZCO thereby acknowledging itself indebted to and promising to pay AZCO, in
consideration of financial advances and services then made, or thereafter made,
the aggregate principal sum of $4,000,000. All advances AZCO has made to date
under this agreement are also evidenced by promissory notes from Eagle.

        On September 3, 1997 AZCO served notice to Eagle stating that, due to
the fact that the work commitment for the license on the Mali project was
unacceptable, AZCO was declaring default of its May 9, 1996 agreement with the
same. In regard to the May 9, 1996 agreement among West African Gold &
Exploration Ltd., Eagle, Lion and AZCO, AZCO gave notice of default to its
joint-venture partners. This dispute is still outstanding and the Company is
currently trying to resolve it. Eagle is currently bankrupt as indicated in Item
3. "LEGAL PROCEEDINGS"

        On April 6, 1998 the Company entered into an agreement with Lines
Overseas Management Ltd. ("Lines"). Under the terms of the Mali agreement, Lines
had originally advanced $500,000 and 125,000 shares of the Company's common
stock owned by it to Eagle for payments to Guefest and other parties. The
Company issued 375,000 shares to Lines in consideration for assigning and
quitclaiming to the company all advances and any other benefit or claim of Lines
related to the Mali agreement.

        On January 21, 1999 the Company announced that it had entered into a
joint venture arrangement with Randgold Resources Ltd. ("Randgold") whereby
Randgold was to acquire the right to earn up to 75% of the Company's interest in
WAG. To earn this consideration Randgold has agreed, over the next 36 months,
to conduct exploration on the WAG concessions at a minimum cost of $2 million,
with the aim of establishing whether there is a viable economic gold resource,
as defined in


                                       4
<PAGE>   5

the agreement, of at least one million ounces. Thereafter Randgold is required
to prepare a Bankable Feasibility Study on any such resource for WAG within a
further 12 months in order to earn its interest therein.

                                       ***

        On December 5, 1997 the Company announced that it had acquired the
option to explore, evaluate and purchase the Benitoite Gem Mine located in San
Benito County, California. AZCO paid $20,000 for the original option and an
additional $20,000 in March of 1999 for an option extension through January 1,
2000. On or before this date the Company has the option to purchase the mine
outright for $1.5 million, unencumbered by royalty.

                                       ***

        On May 22, 1998 the Company entered into an agreement to purchase a
$1,500,000 convertible debenture in and to Oro Argentina Limited ("OAL") for the
purpose of financing the first phase of the Chigue White Bentonite project and
the option payments of OAL as required thereby. OAL has an option to acquire a
50% interest in this Bentonite project that is located in San Juan, Argentina,
pursuant to an agreement dated February 2, 1998 between OAL and Pierre Martre.
The debenture bears interest at 12% per annum and is due on September 1, 2000.
Accrued interest on the debenture for the first year was due on September 1,
1999.

        As at June 30, 1999 $1,159,390 has been drawn against the debenture by
OAL. During the first three quarters $81,969 of accrued interest had been
capitalized.

        On September 1, 1999 OAL defaulted on the interest payment of $136,722
due under the terms of the debenture agreement. The Company expensed all costs
related to this project in fiscal 1999 and is currently considering its
alternatives under the debenture agreement with OAL.

                                       ***

        Effective on August 9, 1999 the Company entered into an "Agreement in
Principal" (the "AIP") with each of Thomas Ford and Calgem, Inc., Mr. Ford's
wholly owned subsidiary, of Redondo Beach, California (collectively, "Calgem"),
pursuant to which, and subject to such legal, accounting and tax advice as may
be provided to the Company by its various professional advisors and counsel
prior to closing, Calgem therein granted the Company an option to purchase all
of the issued and outstanding shares of Calgem and/or business assets of Calgem
in consideration of, among other matters, the issuance of an aggregate of
250,000 common shares of the Company to Calgem together with the payment to
Calgem of an aggregate of $150,000 over a period of one year from regulatory
approval to the transaction.

        In accordance with the terms and conditions of the AIP the Company has
now advanced, by way of interim loan (the "Loan"), an aggregate of $250,000 to
the order and direction of Calgem. The Loan, together with interest accruing
thereon at the rate of ten percent per annum, is to be secured by way of a
senior fixed and floating charge on all of the assets of Calgem and,
furthermore, and in accordance with the terms of the AIP, the Loan is to be
utilized for the sole


                                       5
<PAGE>   6

purpose of purchasing gemstones on behalf of, in the name of and as agent only
for the Company and in conjunction with the present business of Calgem which is
contemplated for acquisition by the Company under the AIP.

        The Company and Calgem, in accordance with the terms and conditions of
the AIP, are presently negotiating the terms and conditions of a proposed formal
agreement which is expected to expand upon, and replace in its entirety, the
AIP, together with the formal terms, conditions and security for the Loan which
is contemplated under the AIP.

REPURCHASE PROGRAM

        On August 6, 1998 the Company approved the repurchase of up to 1,284,024
shares of its issued and outstanding common stock on The American Stock Exchange
commencing on August 13, 1998 and continuing up to and including August 13,
1999. The Company purchased 803,376 shares through the life of the repurchase
program for a total of $490,776.

EXPLORATION AND DEVELOPMENT

        During fiscal 1999 the Company received no material revenues, other than
interest income, as the Company has no mineral properties in production.

        Exploration expense of $229,479 was incurred as the Company funded its
30% share of the Piedras Verdes project.

        Exploration expense in Indonesia totaled $37,628 during fiscal 1999. The
Company continues to investigate the whereabouts of refundable deposits made to
the Indonesian government and written off in fiscal 1998.

        During fiscal 1999 AZCO incurred $409,428 of exploration expense on the
Mali project. Randgold Resources Ltd. successfully completed its first year
commitment under the joint venture agreement on the Mali project and has
indicated to the Company that it intends to continue with the second year of
commitments under the agreement.

        The Company incurred exploration expense of $411,413 for its gemstone
initiative. Expenses of $88,910 and $322,503 were accumulated on the Chivor
Emerald and California Benitoite projects, respectively.

        A total of $1,241,359 was expensed to the Chigue Bentonite project
located in Argentina. This represents the $1,159,390 advanced to OAL under the
debenture agreement and any accrued interest booked to date. The decision to
expense all costs related to this project was made after OAL was expected to
default on its interest payment due on September 1, 1999.

        Costs associated with the due diligence performed on the Black Canyon
Mica project, a total of $293,386, were expensed as exploration expense.

        Exploration expense of $228,258 was allocated to the La Adelita property
in fiscal 1999.

EMPLOYEES

        As of August 15, 1999 there were 9 full-time employees of AZCO. None of
these employees are represented by a labor union contract or a collective
bargaining agreement.

LAWS AND REGULATIONS

        AZCO's interests in its projects will be subject to various laws and
regulations concerning development, production, taxes, labor standards,
environmental protection, mine safety and other matters. In addition, new laws
or regulations governing operations and activities could have a material adverse
impact on AZCO.

FOREIGN COUNTRIES AND REGULATORY REQUIREMENTS

        AZCO has mineral interests located in foreign countries including
Mexico, Indonesia and Mali. Mineral exploration, development and mining
activities on its property interests may be affected in varying degrees by
political stability and the policies of other nations in respect of these
countries. Any changes in regulations or shifts in political conditions are
beyond the control of the Company and may adversely affect its business.
Operations may be affected in varying degrees by government regulations,
including those with respect to export controls, expropriation of property,
employment, land use, water use, environmental legislation and mine safety.
Operations may be also affected in varying degrees by political and economic
instability, economic or other sanctions imposed by other nations, terrorism,
military repression, crime, extreme fluctuations in currency exchange rates and
high inflation.

SEASONABILITY

        The mine and concentrator located at the Black Canyon Mica project are
accessed by crossing a ford in the Agua Fria River. This ford is unusable at
times due to high runoff from streams and snowmelt. From past records the
maximum duration that the ford is unusable is approximately 30 days. To overcome
possible interruptions to production due to weather, a one to two month
stockpile of mica concentrate is expected to be inventoried at the Glendale
process plant.

        It is not anticipated that AZCO's Mexican property interests in the
State of Sonora will be of a seasonable nature. The Company is aware of the fact
that circumstances in other parts of the world, such as Mali and Indonesia, do
make exploration, mining and mineral processing a seasonal endeavor.

COMPETITIVE CONDITIONS

        Many companies are engaged in the exploration and development of mineral
properties. Since many of these companies have substantially greater technical
and financial resources than the Company, the Company may be at a disadvantage
with respect to some of its competitors.

        The marketing of minerals is affected by numerous factors, many of which
are beyond the control of the Company. Such factors include the price of the


                                       7
<PAGE>   8

mineral in the marketplace, imports of minerals from other nations, the
availability of adequate refining and processing facilities, the price of fuel,
electricity, labor, supplies and reagents and the market price of competitive
minerals. In addition, sale prices for many commodities are determined by world
market forces or are subject to rapid and significant fluctuations that may not
necessarily be related to supply or demand or competitive conditions that in the
past have affected such prices.

ENVIRONMENTAL

        In connection with its future mining and processing operations, the
Company will be required to comply with various federal, state and local laws
and regulations pertaining to the discharge of materials into the environment.
The Company will also be required to maintain various permits and licenses
necessary for its operations from appropriate regulatory agencies. Apart from
capital expenditures associated with the construction and maintenance of
facilities required for usual mining and processing activities, the Company does
not anticipate that compliance with environmental laws will have a material
adverse effect upon the capital expenditures, earnings and competitive position
of the Company for the remainder of the current fiscal year, the next fiscal
year or in subsequent periods deemed material by the Company. AZCO is not
currently subject to any material proceedings arising under environmental laws
and regulations.

        In light of the nature of its business the Company could face
significant exposure from potential claims involving environmental matters.
These matters could involve alleged soil, air and water contamination, and
personal injuries or property damage allegedly caused by toxic materials handled
or used by the Company in connection with its mining activities. The Company's
policy is to accrue environmental and cleanup costs when it is probable that a
liability has been incurred and the amount of such liability is determinable.
However, future environment-related expenditures cannot be reasonably quantified
in many circumstances due to the speculative nature of remediation and cleanup
costs, estimates and methods, the imprecise and conflicting data regarding the
characteristics of various types of materials and waste, the unknown number of
other potentially responsible parties involved, the extent to which such costs
may be recoverable from insurance and changing environmental laws and
interpretations. As a result the Company believes its future environment-related
expenditures could potentially become material at some point, but the amount of
such expenditures are uncertain at this time.

ITEM 2. PROPERTIES

BLACK CANYON MICA PROJECT

        On March 9, 1999 the Company completed the acquisition of Arizona Mica,
which owned the rights to develop 43 unpatented lode-mining claims located in
Yavapai County, Arizona. This acquisition was accomplished through the merger of
Arizona Mica with and into the Company's wholly owned subsidiary, Sanchez, with
Sanchez being the surviving corporation in the merger. Sanchez has subsequently
changed its name to AZCO Mica, Inc. ("AZCO Mica").


                                       8
<PAGE>   9

        AZCO Mica has staked 226 additional claims adjacent to the original
property and has defined, through its initial drill program, a deposit of
390,000 tons of muscovite mica resource. Construction is underway on a 10,000
tpy wet ground mica processing facility in Glendale, Arizona, approximately 40
miles from the Black Canyon Mica Mine.

        Through August 31, 1999 the Company has expended a total of $3,361,338
on the construction of the Glendale processing facility and mine development.
Total capital costs for the Black Canyon Mica project are currently budgeted at
$5,387,000. AZCO Mica is expecting to be in production of high quality muscovite
mica by the end of 1999.

PIEDRAS VERDES PROJECT

        The Piedras Verdes property is leased by Cobre del Mayo, S.A. de C.V.
("Cobra del Mayo"), a Mexican corporation that is owned 30% by AZCO and 70% by
Minera Phelps Dodge Mexico S. de R.L. de C.V. ("MPDM"), a subsidiary of Phelps
Dodge. The property consists of approximately 640 hectares and is located in
southern Sonora State, Mexico.

        Prior to the sale of a 70% interest in Cobre del Mayo to MPDM, 242
reverse circulation holes totalling 26,815 meters had been drilled. Since the
sale of the 70% interest in Cobre del Mayo to MPDM 217 holes totaling 47,869
meters have been cored. In addition, the geologic mapping has been expanded,
metallurgical testing has been advanced and a geological and ore deposit model
has been prepared. A pre-feasibility report has been prepared and a $3,600,000
work budget advancing the project towards a bankable feasibility has been
approved and initiated.

        The Company estimates that the Piedras Verdes property contains a 316
million ton deposit grading .37% copper or 2.34 billion pounds of contained
copper (at a .2% cut-off).

SUAQUI VERDE PROJECT

        Cobre de Suaqui Verde, S.A. de C.V., a Mexican corporation that is owned
99.97% by AZCO, leased the Suaqui Verde copper property. Effective July 31, 1999
Cobre de Suaqui Verde, S.A. de C.V., under the direction of the Company,
terminated the June 17, 1991 Suaqui Verdi Agreement with Mrs. Maria Dausinger
and is currently having the mineral concessions transferred to Mrs. Dausinger.

MALI GOLD CONCESSIONS

        On May 9, 1996 the Company signed an agreement with West Africa Gold &
Exploration Ltd., Eagle and Lion that provided for the establishment of a joint
venture holding company, Sanou. Sanou is the sole beneficial owner of a Malian
subsidiary headquartered in Bamako and called Wag, which has a 100% working
interest in the Medinandi and Dandoko concessions located in the Kenieba Gold
Mining District of western Mali. Eagle, the original principal concession owner
through a Malian subsidiary, has caused that subsidiary to convey the
concessions to Wag.

        Effective August 9, 1996 Wag entered into a debenture agreement with
AZCO


                                       9
<PAGE>   10

thereby acknowledging itself indebted to and promising to pay AZCO, in
consideration of financial advances and services then made, or thereafter made,
the aggregate principal sum of $4,000,000. All advances AZCO has made to date
under this agreement are also evidenced by promissory notes from Eagle.

        On September 3, 1997 AZCO served notice to Eagle stating that, due to
the fact that the work commitment for the license on the Mali project was
unacceptable, AZCO was declaring default of its May 9, 1996 agreement with the
same. In regard to the May 9, 1996 agreement among West African Gold &
Exploration Ltd., Eagle, Lion and AZCO, AZCO gave notice of default to its
joint-venture partners. This dispute is still outstanding and the Company is
currently trying to resolve it. Eagle is currently bankrupt as indicated in Item
3. "LEGAL PROCEEDINGS".

        On January 21, 1999 the Company announced that it had entered into a
joint venture with Randgold whereby Randgold acquired the right to earn up to
75% of the Company's interest in WAG. To earn this consideration Randgold has
agreed, over the next 36 months, to conduct exploration on the WAG concessions
at a minimum cost of $2 million, with the aim of establishing whether there is a
viable economic gold resource, as defined in the agreement, of at least one
million ounces. Thereafter Randgold is required to prepare a Bankable
Feasibility Study on any such resource for WAG within a further 12 months in
order to earn its interest therein.

PONGKOR PROPERTIES

        The South and West Pongkor properties adjoin the claim block containing
the 3 million ounce Pongkor Gold Mine in the Bayah Dome area of Western Java in
Indonesia. AZCO does not own any interest in the Pongkor Gold Mine.
Mineralization is known on both claim blocks, neither of which has been explored
by modern methods. In recent years accessibility has been greatly improved with
road access running to the heart of each property. Both properties are highly
prospective for low sulphidation epithermal mineralization, containing
opportunities not only for small tonnage, high-grade mineralization, but also
for bulk-tonnage, open pit targets. There are no proven or probable reserves at
the Pongkor properties at this time.

        AZCO has completed a geologic evaluation of the Pongkor properties and
has compiled an extensive report that is currently being disseminated to a
number of companies, which have expressed an interest in joint-venturing the
properties.

ITEM 3. LEGAL PROCEEDINGS

        On January 22, 1999 the trustee ("Petitioner") in bankruptcy proceedings
against Eagle served a petition, in the Quebec Superior Court, District of Hull,
upon the Company in order to recuperate assets from the Company. The Petitioner
alleges that the Company owes an accounting to the Petitioner for certain stock
in its subsidiary and other alleged assets which, the Petitioner has alleged,
represent hypothetical values that may aggregate, if one accepts the
Petitioner's claims of private stock values, up to $3,400,000. The Company
considers the Petitioner's claims to be without merit and has engaged counsel
that is disputing


                                       10
<PAGE>   11

the matter vigorously on behalf of the Company. To the knowledge of the Company
it is also the largest creditor of Eagle (a claim has been made in excess of
$4,000,000) and, therefore, it is ultimately the Company's and Canadian
counsel's view that the Petitioner will be primarily accountable to the Company
for any assets recovered, whether such should be through the Company or any
other party.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS

        On May 26, 1999 the Company held an annual and special meeting of
shareholders. A brief discussion of the matters voted upon follows:

        1. Alan P. Lindsay, Anthony R. Harvey, Ian M. Gray, Lawrence G. Olson
           and Paul A. Hodges were elected directors of the Company to hold
           office until the next annual general meeting of the Company or until
           their successors are elected or appointed subject to the provisions
           of the Company's by-laws;

        2. It was resolved that PricewaterhouseCoopers would serve as the
           Company's auditors for the fiscal year ending June 30, 1999;

        3. It was resolved that the Voting Agreement among the Company, Arizona
           Mica, Lawrence G. Olson, John O. Rud, Floyd R Bleak, Alan P. Lindsay
           and Anthony R. Harvey be authorized and approved;

        4. It was resolved that the maximum number of shares for which options
           may be granted under the Company's existing Stock Option Plan be
           fixed at 5,950,424; and

        5. It was resolved that the proposal to amend certain issued and
           outstanding options to acquire shares of common stock of the Company
           in the manner as set forth in the Company's Proxy Statement be
           authorized and approved.

        The following table states the number of shares cast as to each matter.

ITEM 7. MANAGEMENT DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
OPERATIONS

GENERAL

        All material revenues received during fiscal 1999 and 1998 were a result
of interest earned on the proceeds of the sale of assets to Phelps Dodge. All
funds raised prior to fiscal 1996 were used in the exploration and development
of the Company's various mineral properties.


                                       13
<PAGE>   14

RESULTS OF OPERATIONS

TWELVE MONTHS ENDED JUNE 30, 1999 COMPARED TO TWELVE MONTHS ENDED JUNE 30, 1998.

        AZCO had a net loss of $4,528,006 in fiscal 1999 compared to net loss of
$3,044,112 in 1998. The increase in net loss for the year ended June 30, 1999
was the result of a provision for income tax benefit booked in fiscal 1998.

        The Company's provision for income tax benefit in fiscal 1998 was
$2,109,237 compared to $4,186 for 1999 due to federal income tax refunds
received as a result of taxes paid on the sale of assets in 1996.

        Exploration expense in 1999 was $3,041,175 as compared to $3,261,405 in
1998. Exploration expense for the current period includes $1,241,359
representing advances and accrued interest under the OAL debenture agreement.
The decision to expense all costs related to this project was made after OAL
defaulted on its interest payment due on September 1, 1999.

        Miscellaneous expense in fiscal 1998 resulted from the $400,000 payment
to AIOC Corporation ("AIOC") as full and final payment of all matters and claims
between AIOC, AZCO and Sanchez.

TWELVE MONTHS ENDED JUNE 30, 1998 COMPARED TO TWELVE MONTHS ENDED JUNE 30, 1997.

        AZCO had a net loss of $3,044,112 for fiscal 1998 compared to net loss
of $8,155,700 in 1997. The reduction in net loss for the year ended June 30,
1998 was the result of a decrease in exploration expenditures of $4,313,601.

        Exploration expense in 1998 was $3,261,405 as compared to $7,575,006 in
1997. The Company, in fiscal 1998, funded $1,101,188 for its 30% share of the
costs related to the Piedras Verdes project compared to $1,846,330 in fiscal
1997. During the fiscal year ended June 30, 1998 AZCO expended $783,672 on the
Mali project as compared to $4,052,316 in the previous fiscal year. In fiscal
1998 a total of $290,678 was expensed against the Indonesian properties in
contrast to $1,211,549 during fiscal 1997. In addition, the Company incurred
expenses of $973,830 relating to its gemstone initiative in fiscal 1998.

        Accounting and legal expenses increased from $254,288 in 1997 to
$386,870 in 1998. Increased legal expense in 1998 is the result of the AIOC
settlement.

        Miscellaneous expense in fiscal 1998 resulted from the $400,000 payment
to AIOC as full and final payment of all matters and claims between AIOC, AZCO
and Sanchez.

LIQUIDITY AND CAPITAL RESOURCES

        For the fiscal year ended June 30, 1998 the Company met its capital
requirements through the proceeds of the sale of assets to Phelps Dodge in 1996.


                                       14
<PAGE>   15

        At June 30, 1999 and June 30, 1998 the Company had cash and cash
equivalents of $12,106,173 and $18,320,882, respectively, and working capital of
$11,813,811 and $19,021,047, respectively. Total liabilities at June 30, 1998
were $299,061 as compared to $387,984 on June 30, 1999.

        The Company feels that its current cash position is strong enough to
fund all capital requirements in fiscal 2000. In the event that a production
decision is made in regards to the Piedras Verdes project it is the Company's
intention to raise additional capital to fund its share of the construction
costs. The continued development of the Black Canyon Mica project is expected to
be funded from the Company's treasury. Funding of the ongoing exploration
projects in California, Mali, Indonesia and Mexico (including approximately $4.1
million in potential pre-production royalties on the Piedras Verdes project over
the next 10 years) is expected to come from either the Company's treasury or
from potential joint venture partners. In the event that is not possible
additional funding will be sought to fund the advance royalties on the Piedras
Verdes project if the Company chooses to retain its interest in that project.

ADDRESSING YEAR 2000

        The Year 2000 issue arises because many computerized systems use two
digits rather than four to identify a year. Date-sensitive systems may recognize
the year 2000 as 1900 or some other date, resulting in errors when information
using year 2000 dates is processed. In addition, similar problems may arise in
some systems that use certain dates in 1999 to represent something other than a
date. The effects of the Year 2000 issue may be experienced before, on or after
January 1, 2000, and, if not addressed, the impact on operations and financial
reporting may range from minor errors to significant systems failure that could
affect an entity's ability to conduct normal business operations. However, the
Company has installed updated accounting software that addresses the potential
year 2000 problem. It is anticipated that there will be no material impact on
the Company. It is not possible to be certain that all aspects of the Year 2000
issue affecting the Company, including those related to the efforts of
customers, suppliers or other third parties, will be fully resolved.

EMPLOYMENT CONTRACTS AND CHANGE-IN-CONTROL ARRANGEMENTS


                                       21
<PAGE>   22

        Effective February 1, 1998 the Company entered into a management
agreement with Alan Lindsay and Associates Ltd. ("Associates"), a British
Columbia corporation owned and controlled by Mr. Lindsay, the Company's Chief
Executive Officer. This new agreement replaces an original May 1, 1989 agreement
in its entirety. This agreement requires all salary amounts otherwise payable by
the Company to Mr. Lindsay to be paid to Associates. Associates is therein
provided with a base fee of $180,000 annually and an allowance for equivalent
benefits enjoyed by Company personnel. The base fee may be renegotiated annually
at the request of either party. In the event that the parties cannot agree then
the base fee is to be increased by the greatest of 5% or the amount of the cost
of living index as published by the Canadian Federal government. The term of
this agreement is for a period of 36 months and renews automatically for
subsequent one-year periods unless either party gives the other party notice of
non-renewal at least 90 days prior to the end of any term. In the event that the
agreement is terminated, or fails to renew due to failure of agreement after the
issuance of a non-renewal notice, Associates will receive a termination fee
equal to either the sum of the buy-out of any outstanding stock options for a
price equal to the average market price of the Company's shares on The Toronto
Stock Exchange multiplied by the number of shares under option and less the
exercise price thereof or, at the election of Associates and subject to
regulatory approval, extension of the option for a year after termination; plus
the greater of:(i) the aggregate remaining base fee for the unexpired remainder
of the term and (ii) the then annual base fee plus one month of base fee for
each year, or portion thereof, served after the effective date. In the event
that Associates is unable to provide the services due to protracted disability
or sickness or the death of its principal (Mr. Lindsay) it may, at any time,
declare such to the Company and may terminate the agreement as a without fault
termination and the termination fee shall be payable. The Company may elect to
effect such termination, and shall pay the termination fee, in the case of death
of Associates' principal or in the event that sickness or disability has
continued for a period in excess of 120 days. It is the Company's estimation
that if the management agreement with Associates was terminated September 23,
1999 Associates would be due $454,420 as a termination fee. This fee represents
$186,670 (Cdn.$275,000) for the buyout of outstanding stock options on September
23, 1999 and $267,750 as the aggregate remaining base fee for the remainder of
the term of the agreement.

        Effective February 1, 1998 the Company entered into a management
agreement with ARH Management Ltd. ("Management"), a British Columbia
corporation owned and controlled by Mr. Harvey, the Company's Vice Chairman.
This new agreement replaces an original May 1, 1989 agreement in its entirety.
This agreement requires all salary amounts otherwise payable by the Company to
Mr. Harvey to be paid to Management. Management is therein provided with a base
fee of $180,000 annually and an allowance for equivalent benefits enjoyed by
Company personnel. The base fee may be renegotiated annually at the request of
either party. In the event that the parties cannot agree then the base fee is to
be increased by the greatest of 5% or the amount of the cost of living index as
published by the Canadian Federal government. The term of this agreement is for
a period of 36 months and renews automatically for subsequent one-year periods
unless either party gives the other party notice of non-renewal at least 90 days
prior to the end of any term. In the event that the agreement is terminated, or
fails to renew due to failure of agreement after the issuance of a non-renewal
notice, Management will receive a termination fee equal to the sum of the
buy-out of any outstanding stock options for a price equal to the average market
price of either


                                       22
<PAGE>   23

the Company's shares on The Toronto Stock Exchange multiplied by the number of
shares under option and less the exercise price thereof or, at the election of
Management and subject to regulatory approval, extension of the option for a
year after termination; plus the greater of: (i) the aggregate remaining base
fee for the unexpired remainder of the term and (ii) the then annual base fee
plus one month of base fee for each year of portion thereof, served after the
effective date. In the event that Management is unable to provide the services
due to protracted disability or sickness or the death of its principal (Mr.
Harvey) it may, at any time, declare such to the Company and may terminate the
agreement as a without fault termination and the termination fee shall be
payable. The Company may elect to effect such termination, and shall pay the
termination fee, in the case of death of Management's principal or in the event
that sickness or disability has continued for a period in excess of 120 days. It
is the Company's estimation that if the management agreement with Management was
terminated September 23, 1999 Management would be due $454,420 as a termination
fee. This fee represents $186,670 (Cdn.$275,000) for the buyout of outstanding
stock options on September 23, 1999 and $267,750 as the aggregate remaining base
fee for the remainder of the term of the agreement.

        Effective August 15, 1994 management agreements were provided to both
Messrs. Harvey and Lindsay that are effective in the event of a change in
control of the Company. Similar management agreements (collectively, the
"Management Agreements") were provided to each of Mr. Modesto, on November 19,
1996, and Mr. Simmerman, on October 23, 1998. The Management Agreements provide
for a lump sum distribution in an amount (taking into account all other
applicable change in control payments by the Company) not to exceed 299% of the
base amount as defined in IRC Section 280G(b) upon a change in control of the
Company. Such "base amount" is generally equivalent to the applicable person's
average annual compensation from the Company includable in his gross income over
the preceding five years. Change of control is therein defined to include only
the following circumstances:

  (i) the acquisition (whether direct or indirect)of shares in excess of 20
      percent of the outstanding shares of common stock of the Company by a
      person or group of persons, other than through a public equity offering by
      the Company;

 (ii) the occurrence of any transaction relating to the Company required to be
      described pursuant to the requirements of item 6(e) of Schedule 14A of
      Regulation 14A of the SEC under the Securities and Exchange Act of 1934;
      or

(iii) any change in the composition of the Board of Directors of the Company
      resulting in a majority of the present directors not constituting a
      majority, provided, that in making such determination directors who were
      elected by, or on the recommendation of, such present majority, shall be
      excluded.

        Effective August 15, 1994 for Mr. Hodges, and effective November 19,
1996 for Dr. Gray, director's agreements (collectively, the "Director's
Agreements") were provided to each of the above that are also effective in the
event of a change in control of the Company. These Director's Agreements provide
for a lump


                                       23
<PAGE>   24

sum distribution not to exceed $100,000 upon a change in control of the Company.
Change in control has the same definition as set forth above in connection with
the Management Agreements.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

        During the fiscal year ending 1999 the entire board of directors acted
as the Company's compensation committee.

ITEM 13. CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

        On March 9, 1999 the Company completed the acquisition of Arizona Mica,
which owned the rights to develop 43 unpatented lode-mining claims located in
Yavapai County, Arizona. This acquisition was accomplished through the merger of
Arizona Mica with and into the Company's wholly owned subsidiary, Sanchez, with
Sanchez being the surviving corporation in the merger. Sanchez has subsequently
changed its name to AZCO Mica, Inc. In connection with the merger, the Company
issued an aggregate of 4,500,000 shares (the "Shares") of its common stock to
the three shareholders of Arizona Mica, Messrs. Lawrence G. Olson, John O. Rud
and Floyd R. Bleak, with each such shareholder receiving 1,500,000 shares of the
Company's common stock. The Shares were issued as "restricted securities", as
that term is defined in Rule 144 promulgated under the United States Securities
Act of 1933, as amended (the "Act"), and the certificates representing the
shares bear a restrictive legend permitting transfer only pursuant to
registration or applicable exemption under the Act.

        As part of the merger transaction Messrs. Olson, Bleak and Rud also
entered into a Voting Agreement (the "Voting Agreement") with the Company,
Arizona Mica and Messrs. Alan P. Lindsay and Anthony R. Harvey, who are
officers, directors and shareholders of the Company. The Voting Agreement has a
term of five years commencing March 9,1999 and the principal provisions of the
Voting Agreement are as follows:

1. Messrs. Olson, Rud and Bleak each grant to the management of the Company, as
such may exist from time to time, the right to vote their Shares in favor of


                                       25
<PAGE>   26

the nominees to the Company's Board of Directors proposed by management at any
meeting of Shareholders of the Company. This provision is implemented through
the grant of an irrevocable proxy by Messrs. Olson, Rud and Bleak to such member
of the Board of Directors of the Company as the Board of Directors may specify
from time to time;

2. The Company agrees to appoint one nominee (the "Nominee") of Messrs. Olson,
Rud and Bleak to the Company's Board of Directors and agrees to include the
Nominee in the management's slate of directors at any meeting, of the
Shareholders of the Company;

3. Messrs. Olson, Rud and Bleak are permitted to sell, assign or otherwise
transfer the Shares covered by the Voting Agreement provided that such transfers
comply with applicable securities laws. Any Shares so transferred will no longer
subject to the terms of the Voting Agreement; and

        Lawrence G. Olson, a non-officer director of the Company since March 15,
1999, is the owner of Olson Precast of Arizona Inc. ("Precast"). Precast,
through a closed bidding arrangement, was awarded the concrete contract on the
Company's Glendale, Arizona, mica processing facility. Precast was compensated a
total of $141,385 for the contract.

AUDITORS' REPORT

TO THE SHAREHOLDERS OF
AZCO MINING INC. (DELAWARE)

We have audited the consolidated financial statements and the financial
statement schedule of AZCO MINING INC. (DELAWARE) and its subsidiaries listed in
the index on page F-1 of this Form 10-K. These financial statements and the
financial statement schedule are the responsibility of the Company's management.
Our responsibility is to express an opinion on these financial statements and
the financial statement schedule based on our audits.

We conducted our audits in accordance with United States generally accepted
auditing standards. Those standards require that we plan and perform an audit to
obtain reasonable assurance 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. An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, these consolidated financial statements present fairly, in all
material respects, the financial position of Azco Mining Inc. (Delaware) and its
subsidiaries as at June 30, 1999 and the consolidated results of their
operations and their cash flows for each of the three years in the period ended
June 30, 1999 in conformity with United States generally accepted accounting
principles. In addition, in our opinion, the financial statement schedule
referred to above, when considered in relation to the basic consolidated
financial statement taken as a whole, presents fairly, in all material respects,
the information required to be included therein.

AZCO MINING INC. (DELAWARE)
Notes to Consolidated Financial Statements
JUNE 30, 1999, 1998 AND 1997
- --------------------------------------------------------------------------------


1   NATURE OF OPERATIONS

    Azco Mining Inc. (Delaware) (the Company) is a U.S. mining company with a
    general business strategy to acquire mineral properties. The Company plans
    to supplement its core assets, the 100% owned Black Canyon Mica Project in
    Arizona and a 30% interest in the Piedras Verdes Project, through its
    acquisition of other mineral properties. As at June 30, 1999, no property
    had proven reserves of commercial ore.

    Although the Company has taken steps to verify title to mineral properties
    in which it has an interest, according to the usual industry standards for
    the stage of exploration of such properties, these procedures do not
    guarantee the Company's title. Such properties may be subject to prior
    agreements or transfers and title may be affected by undetected defects.

2   SIGNIFICANT ACCOUNTING POLICIES

    PRINCIPLES OF CONSOLIDATION

    These consolidated financial statements include the accounts of the Company
    and its majority-owned subsidiaries.

    CASH AND CASH EQUIVALENTS

    The Company considers all liquid investments purchased with a maturity of
    three months or less to be cash equivalents. Cash and cash equivalents are
    stated at cost which approximates market value.

    MINERAL PROPERTIES, PLANT AND EQUIPMENT

    Mineral properties, plant and equipment are recorded at cost.

    Depletion of mineral properties and development costs is to be provided on
    the unit-of-production method, based on proven and probable ore reserves.
    Buildings, plant and equipment is to be depreciated on a straight-line basis
    over their estimated useful lives.

    EXPLORATION PROPERTIES

    The Company expenses prospecting and exploration costs and capitalizes costs
    directly attributable to the acquisition of mineral properties, pending
    determination as to their commercial feasibility (to contain a viable
    mineral deposit). Gains or losses resulting from the sale or abandonment of
    mineral properties are included in operations. Proceeds from sales of
    properties in which the Company has retained an economic interest are
    credited against property costs, and no gain is recognized until all costs
    have been fully recovered.



                                                                             F-7

    PROPERTY EVALUATION

    Recoverability of investments in operating and non-operating properties is
    evaluated periodically. Estimated future net cash flows from each property
    are calculated using estimates of proven and probable ore reserves,
    estimated future prices (considering historical and current prices, price
    trends, and related factors), operating capital, and reclamation costs on an
    undiscounted basis. Where property costs are not recoverable reductions in
    the carrying value of each property are recorded to the extent the remaining
    investment exceeds the estimate of fair value. Changes in the geological and
    engineering interpretations of the Company's ore bodies, mica prices and
    operating costs may change the Company's estimate of proven and probable
    reserves. It is reasonably possible that the Company's estimate of proven
    and probable reserves will change in the near term resulting in additional
    charges for depreciation and reclamation in future reporting periods.

    Where properties are held for sale, recoverability is assessed based on
    management's estimate of fair value. Reductions in the carrying value of
    each property are recorded to the extent the remaining investment exceeds
    fair value, less costs of disposal.

    ENVIRONMENTAL AND RECLAMATION COSTS

    Estimated costs of decommission and reclamation associated with mineral
    properties, plant and equipment, as well as revised regulatory requirements
    are accrued over the life of the mine through periodic charges to earnings
    on the unit-of-production method.

    FURNITURE AND EQUIPMENT

    Furniture and equipment are carried at cost. Replacements, maintenance and
    repairs that do not improve or extend the life of the respective assets are
    expensed. Major renewals and improvements are capitalized. Upon retirement,
    sale or other disposition of furniture and equipment, the cost and
    accumulated depreciation are eliminated from the accounts and the gain or
    loss is included in operations.

    The Company depreciates these assets over their estimated useful lives
    (3 - 5 years) using the straight-line method.

    INCOME TAXES

    The Company accounts for income taxes under Statement of Financial
    Accounting Standards No. 109, "Accounting for Income Taxes." Income taxes
    and liabilities are recognized for the expected future tax consequences of
    events that have been included in the financial statements or income tax
    returns. Deferred tax assets and liabilities are determined based on the
    difference between the financial statements and tax bases of assets and
    liabilities using enacted tax rates in effect for the year in which the
    differences are expected to reverse.



                                                                             F-8

    ESTIMATES

    The preparation of financial statements in conformity with generally
    accepted accounting principles requires management to make estimates and
    assumptions that affect the reported amounts of assets and liabilities and
    disclosure of contingent assets and liabilities at the date of the financial
    statements and the reported amounts of revenues and expenses during the
    reporting period. Actual results could differ from those estimates.

    STOCK-BASED COMPENSATION

    In October 1995, the Financial Accounting Standards Board issued Statement
    of Financial Accounting Standards No. 123, "Accounting for Stock-Based
    Compensation," (SFAS No. 123), which defines a fair value based method of
    accounting for employee (including directors) stock options. However, it
    also allows an entity to continue to account for these plans according to
    Accounting Principles Board Opinion No. 25, "Accounting for Stock Issued to
    Employees," (APB No. 25), provided pro forma disclosures of net income and
    earnings per share are made as if the fair value based method of accounting
    defined by SFAS No. 123 has been applied. The Company has elected to
    continue to measure compensation expense related to employee stock options
    using APB No. 25. The fair value of options granted to non-employees is
    expensed as compensation when options are granted, and the corresponding
    amount is credited to stockholders' equity.

3   CONCENTRATIONS OF CREDIT RISK

    Financial instruments that potentially subject the Company to significant
    concentrations of credit risk consist principally of cash and cash
    equivalents. The Company invests its cash and cash equivalents in high
    quality issuers. The Company, in the normal course of business, maintains
    cash balances in excess of the Federal Deposit Insurance Corporation's
    insurance limit. At June 30, 1999 and 1998, cash equivalents of $11,800,000
    and $18,300,000, respectively, were invested with one bank's trust and
    institutional portfolio department.

4   INVESTMENT AND ADVANCES

    INVESTMENT

    On June 18, 1998, the Company entered into an agreement with Minera Cortez
    Resources Ltd. (Cortez), a private company, whereby the Company was granted
    a right of first refusal for a period of five years to acquire all or any of
    the property interest that Cortez decides to either joint venture, option,
    or dispose of. In consideration, the Company has subscribed for 200,000
    common shares of Cortez at Cdn. $0.25 per share. The Company was also
    granted a right of first refusal for the same period to provide up to 100%
    of any private or public equity or debt financing that Cortez proposes to
    obtain, on similar terms as any third party is willing to provide.

    ADVANCES

    On May 22, 1998, the Company entered into an agreement to purchase a
    $1,500,000 convertible debenture of Oro Argentina Limited (OAL) for the
    purpose of financing the first phase of the Chiqua White Bentonite Project
    and the option payments of OAL. OAL has an option to acquire a 50% interest
    in the Bentonite Project in San Juan, Argentina pursuant to an agreement
    dated February 2, 1998 between OAL and Pierre Martre. The debenture bears
    interest at 12% per annum and is due on September 1, 2000. During the term
    of the debenture, the Company has the option to convert the unpaid balance
    of the principal and interest into common units of OAL at $0.50 per unit,
    where each unit consists of one common share and one warrant, and each
    warrant entitles the Company to purchase an additional common share at $0.60
    per share for a period of two years after conversion. The debenture is
    collateralized by a first floating and fixed charge on the assets of OAL.

    The Company was also granted a two-year option to purchase all of the shares
    of OAL, subject to OAL shareholders' approval. Pursuant to the terms of the
    agreement, if the financing of the second phase of the project is not in
    place after 18 months from the date of issue of the debenture, the Company
    can extend the option for an additional year. The exercise of the option
    will be paid with common shares of the Company at a ratio of one common
    share for two shares of OAL. The shares of the Company issued for 10,136,935
    issued and outstanding shares of OAL and any other shares issued pursuant to
    the purchase option will be placed into a pool for a period of two years,
    25% of which will be released immediately, 25% one year thereafter, and the
    remaining 50% two years thereafter.

    During the year ended June 30, 1999, the Company made the decision to write
    off all the investment in OAL. This resulted in a charge to exploration
    expense of $1,241,359 during the year.

6   EXPLORATION PROPERTIES

    a)  Piedras Verdes Project

        The Piedras Verdes Project is located in southern Sonora, Mexico. During
        the year ended June 30, 1996, the Company sold 70% of its interest in
        the Piedras Verdes Project to Phelps Dodge Corporation (Phelps Dodge).

        Under the terms of the sales agreement with Phelps Dodge, all assets and
        commitments related to this project were transferred to a separate
        company incorporated as Cobre del Mayo, S.A. de C.V. (Cobre). The
        Company maintains a 30% interest and Phelps Dodge a 70% interest in
        Cobre. Under the terms of the Shareholders' and Operator's Agreement
        among Phelps Dodge, Cobre del Mayo, Inc., the Company, and Cobre, the
        Company committed to provide up to $3,000,000 for costs required to
        bring the Piedras Verdes Project to the feasibility stage. As at June
        30, 1999, the Company has advanced $3,865,511 towards the project. The
        Company also committed to funding its 30% of expenditures incurred in
        the feasibility stage. The Company is expensing all costs related to the
        project.

        On March 4, 1997, Cobre entered into a mining exploration and
        exploitation agreement with Compania Minera Serrana, S.A. de C.V. This
        agreement superseded the pre-existing lease. Under the terms of this
        agreement, Cobre has the following commitments to be funded 70% by
        Phelps Dodge and 30% by the Company:

        i)  $10,000 per month from the execution of the agreement until
            production begins;

        ii) three payments of $299,035 due on the date of execution and on the
            first and second anniversaries of the date of execution;



                                                                            F-11

        iii) royalties equal to three percent of the net value of mineral
             production; and

        iv)  advance royalties of $1,000,000 on the third through fifth
             anniversaries of the date of execution, and $1,500,000 on the sixth
             through eleventh anniversaries if commercial production is not met
             by those anniversary dates.

        Following the results of a pre-feasibility study carried out by Phelps
        Dodge and announced in November 1998, Phelps Dodge has approved and
        initiated a $3,600,000 work budget advancing the project towards a
        bankable feasibility. Under the terms of the agreement, the Company is
        responsible for funding 30% of this work.

    b)  Suaqui Verde Project

        On June 20, 1996, the Company entered into a Mineral Exploration and
        Option to Form Company Agreement with Minera Phelps Dodge Mexico (MPDM)
        for the mineral exploration and evaluation of the Suaqui Verde mineral
        concessions in Sonora, Mexico. Under the terms of the agreement, MPDM
        could earn a 70% interest in the concessions by incurring exploration
        expenditures of $2,000,000 on the project over three years, funding the
        completion of a comprehensive feasibility study, and paying the Company
        $25,000 annually.

        During the year ended June 30, 1998, MPDM terminated the option
        agreement with the Company.

        On July 17, 1999, the Company decided to terminate the agreement with
        the property owners and made the final payment due under the agreement.
        The Company intends to leave the property in good standing and have paid
        the mineral duties on the concessions until December 31, 1999.

    c)  La Adelita Property

        On July 21, 1998, the Company entered into an option agreement with
        Cortez whereby the Company was granted an option to earn up to 70%
        interest in the La Adelita property in Sonora, Mexico under the
        following terms:

        i)   by subscribing to 100,000 common shares of Cortez at Cdn. $0.25 per
             share;

        ii)  by making option payments and paying finder's fees on behalf of
             Cortez totalling $165,000 over the next five years; and

        iii) by incurring exploration expenditures on the property totalling
             $500,000 over the next three years.

        During the year ended June 30, 1999, the company has expended $228,256
        on the La Adelita property and thus completing its first year's
        commitment to the property.

        On June 10, 1999, the Company acquired 100% interest in the Silverado
        property, which surrounds the La Adelita property, from Cortez for
        $20,000 and 30,000 of the Company's shares.



                                                                            F-12

    d)  Mali Project

        On May 9, 1996, the Company entered into a Memorandum of Agreement with
        West African Gold and Exploration, Ltd. (WAG), a British Virgin Islands
        company, Eagle River International Limited (Eagle River), a Vanuatu
        corporation, and Lion Mining Finance Limited (Lion Mining), a United
        Kingdom corporation. Eagle River has purchased properties in Mali,
        Africa from Guefest, a Russian mining consortium. Under the terms of
        this agreement, the properties were transferred to West African Gold
        (Mali) Inc. (WAG (Mali)) on July 7, 1997. Shares in this corporation
        have been transferred to Chaplin Holding Ltd., a Bahamian company, which
        has changed its name to Sanou Mining Corporation (Sanou). The Company
        currently holds a 100% interest in Sanou.

        On May 17, 1996, under the terms of the above agreement, the Company
        issued an irrevocable standby letter of credit in the amount of
        $1,000,000 to guarantee the development of certain mineral concessions
        in Mali. The Company, on behalf of Eagle River, Lion Mining, and WAG,
        had guaranteed $1,000,000 of development by May 15, 1997 to keep the
        properties in good standing. During the year ended June 30, 1997, the
        Company funded $4,052,316 for operating costs on the Mali Project, which
        exceeds the required expenditures. The operating costs are included in
        exploration costs in the accompanying statement of loss.

        On September 3, 1997, the Company served notice to Eagle River that it
        was declaring default of the Mali agreement as the work commitment for
        the licence on the Mali Project was unacceptable. Under the terms of the
        agreement, Eagle River and Lion Mining have to repay all advances made
        by the Company towards the Mali Project. These advances were secured by
        promissory notes from Eagle River and debentures from Societe Olifer de
        Falome (SOF) and WAG Mali in the amount of $4,000,000. The Company is in
        the process of foreclosure on these securities and, as a consequence,
        takes the position that it is the 100% owner of the mining concessions
        through its subsidiaries WAG and Sanou and will pursue Eagle River and
        SOF for any value shortfall.

        On November 18, 1997, the Company entered into an agreement with Lion
        Mining forming a joint venture called the Kingfisher Venture created to
        pursue profitable exploitation of mineral opportunities located by Lion
        Mining. Pursuant to the terms of the agreement, Lion Mining will seek
        and make available to the venture mineral opportunities coming to them
        in which they are capable of participating, and the Company has the
        right of first refusal on these opportunities. The term of the venture
        is the longer of three years or the payout of the Negative Balance plus
        six months, expiring on December 31, 2010. The Negative Balance is equal
        to the total expenditures related to the Mali agreement less all
        recoveries. Lion Mining has also assigned to the Company all its rights
        and interests in the Mali agreement and has agreed to cooperate fully
        with the Company in pursuit of any remedies against Eagle River. The
        Company has released and discharged Lion Mining of all suits, debts, and
        claims related to the Mali agreement. The Company plans to foreclose on
        the promissory notes of Eagle River.

        On December 18, 1997, WAG (Mali) was granted a renewable exploration
        agreement on the Mali Project by the Mali Ministry of Mines and Energy.
        The agreement ran through December 1998 and has a work commitment of
        $3,360,000 assigned to it. As of June 30, 1998, this work commitment has
        been fulfilled.



                                                                            F-13

        On April 6, 1998, the Company entered into an agreement with Lines
        Overseas Management Ltd. (Lines). Under the terms of the Mali agreement,
        Lines had originally advanced $500,000 and 125,000 shares of the Company
        owned by it to Eagle River for payments to Guefest and other parties.
        The Company has agreed to issue 375,000 of its shares to Lines in
        consideration for assigning and quitclaiming to the Company all advances
        and shares and any other benefit or claim of Lines related to the Mali
        agreement. These shares were issued on September 17, 1998.

        On January 22, 1999, the trustee ("Petitioner") in bankruptcy
        proceedings against Eagle River International Ltd. ("Eagle") served a
        petition, in the Quebec Superior Court, District of Hull, upon the
        Company in order to recuperate assets from the Company (see note 11).

        On March 31, 1999 the Company announced that it had entered into a joint
        venture with Randgold Resources Ltd. ("Randgold") whereby Randgold
        acquired the right to earn up to 75% of the Company's interest. To earn
        this consideration Randgold has agreed, over the next 36 months, to
        conduct exploration on the WAG concessions at a minimum cost of $2
        million, with the aim of establishing whether there is a viable economic
        gold resource, as defined in the agreement, of at least one million
        ounces. Thereafter Randgold shall prepare a Bankable Feasibility Study
        on any such resource for WAG within a further 12 months in order to earn
        its interest therein.

    e)  Indonesia Projects

        During the year ended June 30, 1997, the Company entered into certain
        agreements to obtain the rights to explore properties in Indonesia. As a
        part of the agreements, the Company was obligated to pay all costs
        required under Indonesian law. These costs include funds required to be
        put on deposit with the Indonesian Ministry of Mines to obtain Contracts
        of Work (CoWs).

        At June 30, 1997, the Company had a total of $615,255 on deposit with
        the Indonesian Ministry of Mines as security for CoWs on mineral
        concessions covering 121,623 hectares. During the year ended June 30,
        1998, the Company decided not to pursue exploration on 83,940 hectares.

        As a result, the Company received a refund of $244,750 in deposits on
        one of the properties. The remaining $370,505 in deposits was written
        off to exploration expenses in the year ended June 30, 1998.

    f)  Benitoite Project

        On December 1, 1997, the Company entered into an agreement whereby it
        was granted an option to purchase the Benitoite mineral property in San
        Benito County, California for a purchase price of $1,500,000. The
        Company can exercise the option on or before February 1, 1999. Pursuant
        to the terms of the agreement, the Company has made a non-refundable
        payment of $20,000 to the property owners.

        On March 18, 1999 the Company made an additional payment of $20,000 to
        extend the option to January 1, 2000.



                                                                            F-14

7   STOCK OPTIONS

    The Company has elected to follow APB No. 25 and related interpretations in
    accounting for its stock-based employee compensation arrangements. Under APB
    No. 25, as the exercise price of the Company's stock options equals the
    market price of the underlying stock on the date of grant, no compensation
    expense is recognized.

    The Company has a Stock Option Plan (the Plan) dated July 24, 1989, as
    amended, for the granting of options to purchase common stock. The board of
    directors may grant options to key personnel and others as it deems
    appropriate. There are no vesting requirements under the Plan. The options
    are exercisable over a maximum term of five years.

    Pro forma information regarding net income and earnings per share is
    required by SFAS No. 123, and has been determined as if the Company had
    accounted for its stock option plan under the fair value based method of
    SFAS No. 123. The fair value of these options was estimated at the date of
    grant using a Black-Scholes options valuation model with the following
    weighted-average assumptions for fiscal 1999: risk-free interest rate from
    4.07% to 5.50%, no dividend, volatility factor of the expected market price
    of the Company's common stock of 0.71, and an expected life of five years.

    The Black-Scholes options valuation model was developed for use in
    estimating the fair value of traded options that have no vesting or trading
    restrictions and are fully transferable. In addition, option valuation
    models require the input of highly subjective assumptions including the
    expected stock price volatility. The Company's employee stock options have
    characteristics significantly different from those of traded options.
    Changes in the subjective assumptions can materially affect the fair value
    estimate.

    For the purposes of pro forma disclosure, the estimated fair value of the
    options of $303,580 (1998 - $59,141; 1997 - $376,394) is expensed when the
    options are granted as the options are fully vested when granted. Additional
    fair value of the options of $269,760 (1998 - $nil; 1997 - $nil) is expensed
    when certain options were repriced during the year. The Company's pro forma
    information for fiscal 1999, 1998 and 1997 follows:

    At June 30, 1999, the Company had net operating loss carryforwards for
    Arizona income tax purposes of approximately $9.1 million (1998 - $7.6
    million). These losses expire in the amount of $5.3 million on June 30,
    2002, $2.3 million on June 30, 2003 and $1.5 million on June 30, 2004.

    At June 30, 1999, the Company had net operating loss carryforward for
    federal income tax purposes of approximately $2.5 million (1998 - $nil).
    These losses expire on June 30, 2019.

9   EARNINGS PER SHARE

    In February 1997, Statement of Financial Accounting Standards No. 128,
    "Earnings Per Share," (SFAS No. 128) was issued. In accordance with SFAS No.
    128, the Company has adopted the new standard in the quarter ended December
    31, 1997 and for the year ended June 30, 1998. SFAS No. 128 requires dual
    presentation of basic and diluted earnings per share (EPS) on the face of
    the consolidated statement of loss, and a reconciliation of the components
    of the basic and diluted EPS calculations in the notes to the financial
    statements. Basic EPS excludes dilution and is computed by dividing net
    income (loss) by the weighted average number of shares outstanding. Diluted
    EPS reflects potential dilution that would occur if securities or other
    contracts to issue common stock were exercised or converted into common
    stock. The following is the reconciliation of EPS for fiscal 1999, 1998 and
    1997:

11  CONTINGENCIES AND COMMITMENTS

    EAGLE RIVER INTERNATIONAL LTD.

    LITIGATION

    On January 22, 1999, the trustee ("Petitioner") in bankruptcy proceedings
    against Eagle River International Ltd. ("Eagle") served a petition, in the
    Quebec Superior Court, District of Hull, upon the Company in order to
    recuperate assets from the Company (see note 6(d)). It is the understanding
    of the Company and its Canadian legal counsel that the Petitioner alleges
    that, through the Company's involvement with Eagle in the Mali Project, the
    Company is guilty of contractual breaches in excess of $3,400,000. In
    management's opinion this claim is unfounded, although the eventual outcome
    of the case is not yet determinable.

    Copper Purchase Agreement

    The Company had formerly entered into a Copper Purchase Agreement relating
    to the copper output of the Sanchez Project. After sale of the Sanchez
    Project, the Company was informed that it was in alleged violation of this
    agreement. A lawsuit was filed against the Company by AIOC Corporation
    (AIOC). The Company agreed to binding arbitration with AIOC and received a
    dismissal of the lawsuit on February 8, 1996, under terms of the Stipulation
    and Order of Compromise and Dismissal.

    Under the terms of the Company's Stipulation and Order of Compromise and
    Dismissal with AIOC, the Company placed $4,000,000 into escrow to satisfy
    any award in the arbitration. During the year ended June 30, 1998, the
    Company settled the dispute and paid $400,000 to AIOC. This amount has been
    recorded as a legal settlement cost. The remaining deposit with interest
    held in escrow has been refunded to the Company.



                                                                            F-19

    EMPLOYMENT AGREEMENTS

    The Company has entered into agreements with four officers and two
    directors. The agreements provide that if there is a change in control of
    the Company and the officer leaves the employment of the Company, for
    whatever reason (other than discharge for cause, death, or disability)
    within six months after such acquisition of control, the officer shall
    receive a lump sum cash payment pursuant to certain limitations of the
    Internal Revenue Code. In addition, the officers will continue to be covered
    by all of the Company's medical, health, life, and dental plans for 24
    months after such change of control. The directors shall receive a lump sum
    cash payment in the amount not to exceed $100,000.

    In addition, the Company has entered into separate management agreements
    with its President and its Executive Vice-President. These agreements were
    effective February 1, 1998 for a term of 36 months, and provide that in the
    event of termination or failure to renew, the officer will receive a
    termination fee equal to the sum of:

    a)  buy-out of any outstanding stock options at the average market price of
        the Company's shares and less the exercise price, or at the officer's
        election and subject to regulatory approval, extension of the option for
        a year after termination

    b)  greater of the aggregate remaining base fee for the unexpired remainder
        of the term, or an annual base fee plus one month of base fee for each
        year of service after the effective date of the agreement.

    During the year ended June 30, 1999, the Company paid $403,500 in management
    fees to companies controlled by directors. This amount has been recorded as
    salaries expense.

    PUBLIC RELATIONS AGREEMENT

    On April 1, 1998, the Company entered into an agreement with the Wall Street
    Group to provide financial public relations services to the Company.
    Pursuant to the terms of the agreement, the Company will pay a monthly cash
    fee of $5,000 and has granted a five-year stock option on 84,000 common
    shares of the Company at $1.20 per share. If the agreement is not cancelled
    or modified after 12 months, the same terms will apply for the next 12
    months, except that an additional five-year stock option on as many common
    shares as can be purchased for $100,000 will be granted, with an exercise
    price equal to the closing bid price on April 1, 1999. Each year thereafter,
    this additional stock option grant and formula will be maintained until the
    agreement is cancelled or modified.

    On April 1, 1999, the Company cancelled the agreement. The stock option was
    still outstanding at June 30, 1999.

    LEASE COMMITMENTS

    The Company is obligated under a long-term operating lease for its office
    space in Vancouver, British Columbia, through April 1999. The lease contains
    a renewal option of five years. The aggregate annual rental commitment under
    the leases is as follows:



                                                                            F-20

    Rental expense, net of sublease income, for the years ended June 30, 1999,
    1998 and 1997 was $60,732, $60,514 and $68,121, respectively.

12  FAIR VALUE OF FINANCIAL INSTRUMENTS

    The carrying amounts of cash and cash equivalents and restricted cash
    approximated fair value as of June 30, 1999 and 1998 because of the
    relatively short maturity of these instruments. It was not practicable to
    estimate the fair value of advances to OAL as at June 30, 1998 because the
    ultimate recovery of the advances was dependent on the ability of OAL to
    realize its exploration and development assets, which are subject to the
    measurement uncertainty inherent in such assets. This investment was written
    off during the year ended June 30, 1999.

13  FOURTH QUARTER CHARGES

    During the fourth quarter of fiscal 1999, the Company recorded a
    compensation expense credit of $123,400 relating to an over-provision in the
    accounting of stock options granted to non-employees under SFAS No. 123 in
    the third quarter of fiscal 1999. The company recognized a deferred tax
    asset of $754,800 to offset the deferred tax liability arising on the
    acquisition, during the third quarter of fiscal 1999, of the Black Canyon
    Mica Project. In addition, the Company wrote off $1,241,359 investment in
    Oro Argentina Limited due to uncertainty of recoverability.

14  NEW PRONOUNCEMENTS

    The Financial Accounting Standards Board has issued Statement of Financial
    Accounting Standards No. 133, "Accounting for Derivative Instruments and
    Hedging Activities." The Company is currently assessing the impact of this
    statement for fiscal years beginning after June 15, 2000.

                  condition specified in any offer to the remaining shareholder;

        10.4.2    the disposal is concluded within 120 (one hundred and twenty)
                  days of the expiry of the offer to the remaining shareholder;

        10.4.3    the purchasing party becomes a party to this Agreement;

        10.4.4    the purchasing party shall have the capacity at the time of
                  sale to perform the obligations of the offeror and to enter
                  into all such guarantees, suretyships, or any other obligation
                  of the offeror, failing which, at the sole discretion of the
                  other shareholders, the offeror shall not be relieved of any
                  obligations arising from this agreement or any other agreement
                  entered into in the course of the development of the Permits.

        10.4.5    If at the expiry of the offer period the remaining shareholder
                  has notified its willingness to accept the offered identified
                  shares, WAG shall record the transfer of such identified
                  shares to the remaining shareholder who shall be bound to pay
                  the price for the identified shares and the offeror shall be
                  bound upon payment to transfer the shares to the remaining
                  shareholder.

10.5    If upon the expiry of the offer period the aggregate of the shares for
        which acceptances have been received is less than the aggregate of the
        identified shares, the offeror may within 14 days elect to withdraw the
        offer in which case the offer shall be deemed to be withdrawn and the
        offeror shall be entitled to retain the identified shares.

10.6    The offeror shall execute and deliver, or cause to be delivered to each
        purchaser of identified shares such documents, duly completed and
        signed, as are necessary to transfer complete and full title in respect
        of the shares sold to those purchasers.

10.7    Notwithstanding the provisions of this clause, any share may be
        transferred by either shareholder to an Affiliate provided such
        Affiliate becomes a party to this Agreement and the rights of
        pre-emption conferred on the shareholders shall not arise on the
        occasion of such transfer.

                               FURTHER EXPENDITURE

11.1    Once Randgold has expended US $2,000,000.00 on Exploration during the
        three year period and has produced the Bankable Feasibility Study, it
        will be the unrestricted owner of 75% of WAG constituting the Randgold
        Shares and such shall be released to Randgold from escrow.

11.2    After Randgold has expended funds on Exploration and produced the
        Bankable Feasibility Study then the Board of WAG will thereafter call
        for contributions from its

                                       11
<PAGE>   12

        shareholders for funds for further Budgets in accordance with programs
        and Budgets approved by the Board. A Budget requiring cash calls in
        excess of $1,000,000US shall be approved unanimously by the Board but in
        the event of disagreement and dead-lock extending in excess of 30 days,
        the Manager shall have a casting vote which shall determine the issue. A
        cash call for a Budget shall be for no more than the projected Budget
        requirements for the succeeding quarter, unless additional expenditure
        is approved by all parties.

11.3.   Within 45 days of the approval by the Board of such program and budget,
        the shareholders may elect to contribute to such program and budget as
        follows:

        11.3.1    in proportion to their then existing shareholding as at the
                  beginning of the period covered thereby; or

        11.3.2    in some lesser amount than its respective shareholding, or not
                  at all, in which case its shareholding shall be recalculated
                  as provided in Article 13.

11.4    In the event that none of the shareholders will contribute their portion
        of a Budget, or in the event that any part of a Budget is unfunded and
        no shareholder will assume the unfunded portion, then the Budget shall
        be considered void and the Manager and the Board shall produce a new
        Budget for which the shareholders will fund the entire Budget.

11.5    From the commencement of a Budget the Manager shall immediately notify
        the Board of any material departure from an approved program and Budget.
        If the Manager exceeds an approved Budget by more than 10% (ten
        percent), then the excess over 10% (ten percent), unless directly caused
        by an emergency or unexpected expenditure or unless otherwise authorized
        by the Board and the parties hereto, shall be for the sole account of
        the Manager, and such excess shall not be included in the calculations
        of the shareholding for the purpose of dilution or otherwise. Budget
        overruns of 10% (ten percent) or less shall be borne by the contributing
        parties in proportion to their respective shareholding as of the
        beginning of the period covered by the program and budget in question.
        Such overrun shall be funded by the parties in accordance with their
        shareholding within 30 days of invoice by the Manager.

11.6    From the commencement of a Budget in case of emergency, the Manager may
        take any action it deems necessary to protect life, limb or property, to
        protect the assets or to comply with law or government regulation.
        Likewise, the Manager may make expenditures for unexpected events which
        are beyond its reasonable control and which do not result from a breach
        by it of its standard of care. In the case of either an emergency or
        unexpected expenditure, the Manager shall promptly notify the parties of
        the emergency or unexpected expenditure, and the Manager shall be
        reimbursed therefore by the parties in proportion to their respective
        shareholding as of the beginning of the period covered by the then
        current program and budget.

11.7    Within 15 (fifteen) days of a shareholder's election in terms of
        subclause 11.3 for a Budget which has been fully committed for funding
        the shareholders shall advance to the Manager their proportionate share
        of the estimated amount of the forthcoming calendar quarter adjusted if
        necessary to take account of the election. Thereafter on the basis of
        the approved program and Budget, the Manager shall submit to the
        shareholders 15 days prior to the last day of each calendar quarter a
        billing for estimated cash requirements for the next ensuing calendar
        quarter. The shareholders shall advance to the Manager their
        proportionate share of the estimated amount by the first day of such
        next ensuing quarter. Time is of the essence for payment of such
        billings.

                                       12

11.8    If a shareholder fails to meet cash calls in the amount and at the times
        specified in clause 11.7 they shall be in default. Such default if not
        rectified within 14 (fourteen) days.

        following receipt of written notification by the Manager shall result in
        a dilution by the shareholder as provided for in clause 13.

                           BANKABLE FEASIBILITY STUDY

12.1    At any time during the duration of the first 36 months of the Agreement
        the Manager may decide that the results of the Exploration warrants the
        preparation of a Bankable Feasibility Study.

12.2    To the extent that Randgold has not completed its funding of
        US$2,000,000 in Exploration expenditure then Randgold shall apply such
        unexpended amount to the funding of the Bankable Feasibility Study.

                                   ARTICLE 13

                            DILUTION OF SHAREHOLDING

13.1    Once Randgold has fully earned its interest in accordance with the terms
        of this Agreement then the shareholders of WAG shall contribute to the
        costs of Budgets and programs in proportion to their shareholding at any
        relevant time.

13.2    It is anticipated, and permitted, that the parties shall largely or
        fully fund Budgets through inter-corporate loans to WAG and it is
        acknowledged that all funds advanced to date are in the form of loans.
        All loans shall be advanced under a first charge security which shall
        rank between the parties equally and ratably in accordance with their
        shareholder interests, subject only to subordination to bona fide third
        party lenders approved by the Board or to charges required by law. Until
        Randgold has fully earned its Randgold Shares, all loans shall rank
        equally and ratably with the actual amount of outstanding loans as
        between Azco and Randgold. It is acknowledged that in regard to Azco's
        historical debt of approximately $4,000,000 US (the "Azco Debt"), and
        the debenture of such amount outstanding on the books of WAG, that upon
        Randgold earning its Randgold Shares the Azco Debt shall be amended to
        provide that such shall be an encumbrance only on the interest of Azco
        in WAG, shall not be a general liability of such company, and shall only
        be paid from the revenue of WAG attributable to Azco's equity interest
        in WAG.

13.3    In the event that Mali elects to receive a non-contributory 15% and
        further elects to receive a 5% working interest then the other
        shareholders in the mining company will be required to contribute the
        proportionate costs towards further Budgets in the following proportions
        or dilute:

13.3.1  If Mali elects to receive the 15% carried plus the 5% working interest,
        then the shareholding and contributions in the mining company will be:

                 remain with its 15%

        non-contributory interest, the parties shareholding and contributions
        will be:

        Mali                 15%             0%
</TABLE>

13.4    The shareholding of that party electing to reduce its contribution to a
        Budget or not to contribute at all or failing to make a cash call, shall
        be recalculated at the time of election or default and abated in
        accordance with the formula set out hereunder. The percentage interest
        of a Party shall be recalculated by multiplying such percentage interest
        by a factor (hereafter called "X"), expressed as a decimal factor
        derived by the following formula. The Party not being diluted shall have
        its interest increased by the interest lost by the diluting party
        resulting from the following formula:

<TABLE>
<S>                          <C>
                                 A + B
                             X = -----
                                 C + D
</TABLE>

        Where X  is the recalculation factor; and

        A is the deemed expenditure of the party whose interest is being diluted
        and shall be the sum of the following as identified for each party:

        1)     US $2,000,000 (two million United States Dollars) plus all other
               costs to the completion of the Bankable Feasibility Study for
               Randgold (the "Randgold Expenses") plus Azco's historical
               expenditures of sec. 13.4(3) below multiplied by Randgold's
               contribution percentage of sections 13.3.1 or 13.3.2, dependent
               upon Mali's election, shall be deemed for Randgold;

        2)     Azco's contribution percentage of section 13.3.1 or 13.3.2,
               dependent upon the relevant Mali election, multiplied by the
               Randgold Expenses shall be deemed for Azco; and

        3)     Azco's historical expenditure to acquire the Permits and to
               explore the same in the amount of $4,000,000 US for Azco (less
               the amount paid by Randgold to Azco for the camp);

        B is the diluting party's actual contribution to Budgets to date;

        C is the total deemed expenditure for a Party, of numerator A 1 to 3
          above;

        D is the total amount which a Party should have contributed in
          accordance with its contributory interest of sections 13.3.1 or
          13.3.2.

13.5    Once a party has suffered dilution of its shareholding, it shall be
        entitled to resume contributions to Budgets for the next quarter and
        thereafter, only at the diluted level of its shareholding, provided
        however, that the shareholding of a diluted party may be increased in
        the event of any other party subsequently itself suffering dilution of
        its shareholding in terms of the above. However, a diluted party may
        employ a one time election at any time, for a period of 12 months
        following dilution, to regain its interest ("Repurchase Election") by
        paying the party which has borne the additional cost the total costs
        during that period the paying party has borne for the other party's
        diluted interest to the date of the Repurchase Election plus a fifty
        (50%) percent premium plus interest at

                                       14
<PAGE>   15

        US Treasury Department month end prime plus 4% and calculated monthly on
        the non-premium amount.

13.6    If a party's interest is diluted to 5% or less of WAG then it shall
        relinquish all of its interest and shareholding and receive a 4% net
        profits interest ("NPI"). The NPI shall be calculated on the net profit
        determined in accordance with Schedule "5" hereto.

                                   ARTICLE 14

                                     MANAGER

14.1    Appointment

        14.1.1   Each party hereby appoints Randgold as the Manager of WAG for
                 the period in which Randgold is the largest shareholder of WAG
                 and agrees that the Manager shall have overall management
                 responsibility for WAG. The parties agree that Randgold may
                 from time to time appoint an Affiliate to be Manager to act on
                 its behalf under this Agreement and that, in this respect,
                 Randgold may appoint Affiliates to manage (in accordance with
                 this Agreement) all or any other specific areas to which this
                 Agreement relates. Randgold agrees to serve as Manager unless
                 and until it resigns (whether by Randgold nominating an
                 Affiliate to act as Manager in its place or otherwise) or is
                 deemed to resign as provided in clause 14.4

        14.1.2   If Randgold assigns or transfers its shares in WAG to an
                 Affiliate then, if Randgold is the Manager at the time of such
                 assignment or transfer, Randgold shall continue as Manager
                 under this Agreement, unless it otherwise determines to
                 transfer the Manager's duties to such Affiliate.

        14.1.3   In the event that an Affiliate succeeds Randgold as Manager
                 Randgold and the Affiliate shall take such transitional steps
                 as are necessary for the Affiliate to assume and perform the
                 powers and duties of Manager under this Agreement.

        14.1.4   Subject to notice to the Board and non-objection thereby and
                 subject to Randgold's continuing obligations of supervision,
                 Randgold may sub-contract part or all of its duties as Manager
                 to reputable and capable independent contractors so long as
                 such sub-contracts do not materially add to cost in the areas
                 where Randgold has capability to perform the duties.

14.2    Powers And Duties Of Manager

        Subject to the provisions of this Agreement, the Manager shall have the
        following powers and duties:

        14.2.1   The Manager shall, by itself or through its employees, agents,
                 independent contractors or Affiliates, manage, direct and
                 control operations on behalf of WAG in regard to the Permits,
                 and for that purpose shall have control of all the Assets. The
                 Manager shall conduct operations in accordance with programs
                 and budgets adopted by, and the lawful decisions and directions
                 of the Board, but shall otherwise be entitled to conduct
                 operations in the Manager's absolute discretion.

        14.2.2   The preparation of budgets and the expenditure of funds shall
                 be at Randgold's sole discretion, save that such expenditure
                 shall comply with the undertaking by Randgold to expend $2
                 million on Exploration on the Permit

                                       15

                 the best terms available, taking into account all of the
                 circumstances;

        14.2.4.2 obtain such customary warranties and guarantees as are
                 available in connection with such purchases and acquisitions;

                 and clear of all liens and encumbrances, except for those

                 acquisition of such Assets; and

        14.2.4.4 pay, on behalf of such parties as are liable to contribute, all
                 costs and expenses incurred through the conduct of Operations.

14.2.5  The Manager shall conduct such title examinations and, to the extent it
        is able to do so in view of which entity holds title to the Permits,
        cure such title defects as may be advisable in the reasonable judgment
        of the Manager.

14.2.6  The Manager shall:

        14.2.6.1 make or arrange for all payments required by permits, licenses,
                 concessions, contracts and other agreements related to the
                 Permits;

        14.2.6.2 pay all taxes, assessments and like charges on Operations and
                 Assets except taxes determined or measured by a party's sales
                 revenue or net income; and

        14.2.6.3 do all other acts, including the preparation and lodgment of
                 such reports as are required by law, as are reasonably
                 necessary to maintain the Assets in good standing.

14.2.7  The Manager shall:

        14.2.7.1 apply for all necessary permits, licenses and approvals
                 required for or in connection with operations;

        14.2.7.2 comply with applicable laws and regulations;

        14.2.7.5 shall prosecute and defend on behalf of WAG but shall not
                 initiate

        without  consent of the Board, any litigation or administrative
        proceedings arising out of Operations. The parties shall have
        the right to participate, at their own expense, in such
        litigation or administrative proceedings;

14.2.8  The Manager shall notify each party of any litigation or administrative
        proceeding of which it becomes aware which is instituted against the
        Manager or the parties arising out of Operations, and of any material
        matter arising out of Operations which could reasonably be regarded as
        giving rise to a right in the parties or the Manager to commence any
        litigation or administrative proceeding. If the Board does not consent
        to the Manager initiating a litigation or administrative proceeding, a
        party may institute that proceeding in its own name and at its own
        expense, but shall keep the Manager and each other party fully informed
        of the progress of the proceeding and shall indemnify the Manager and
        each other party against all losses, liabilities, damages and such costs
        which they may incur in respect of or arising out of the proceeding.

14.2.9  The Manager shall procure and maintain such insurance as may be required
        by all applicable laws, rules or regulations and good mining practice in
        respect of Operations. No other insurance shall be provided for the
        benefit of the parties. However, a party may procure and maintain at its
        cost and expense such other specific insurance relating to Operations as
        it shall consider necessary and such other insurance shall be solely for
        the benefit of the party procuring the same and the premium therefor
        shall be for the account of that party. Further, such insured party
        shall indemnify each other party against any liabilities incurred by the
        other party as a result of a claim by the relevant insurer, whether by
        subrogation or otherwise.

14.2.10 The Manager may not dispose of Assets, whether by sale, assignment,
        abandonment or other transfer, except with the consent of all of the
        parties. Notwithstanding, the Manager shall carry out all procedures
        required on behalf of WAG to abandon any part of the Permits required by
        law and to the extent determined by the Board and the Manager shall also
        act to secure such new permit areas as the Board may determine to
        acquire.

14.2.11 The Manager shall have the right to carry out its powers, duties and
        obligations under this Agreement through its employees, agents,
        independent contractors or Affiliates.

14.2.12 The Manager shall keep and maintain all required accounting and
        financial records in respect of WAG in accordance with customary cost
        accounting practices in the mining industry.

14.2.13 The Manager shall select and employ at competitive rates all supervision
        and labour necessary or appropriate to all Operations. All persons
        engaged or employed hereunder, the number thereof, their hours of labour
        and their compensation shall be determined by the Manager, and they may
        be employees of the Manager.

14.2.14 At the end of each half year, the Manager shall provide to the parties a
        report on Operations which shall include copies of all information
        acquired in Operations, including, but not limited to, maps, drill logs,
        core tests, reports, surveys, assays, analyses, production reports,
        Operations, technical,

                                       17
<PAGE>   18

        accounting and financial records. In addition, the Manager shall, upon
        receiving reasonable notice and at reasonable times, allow the parties
        at their sole risk and expense, and subject to reasonable safety
        regulations, to:

        14.2.14.1  inspect the Assets and Operations, but shall be entitled to
                   request that the inspecting parties first undertake not
                   unreasonably to interfere with Operations; and

        14.2.14.2  have access to, and inspect and copy, all information
                   relating to Operations.

        14.2.15    The Manager shall undertake all other activities reasonably
                   necessary to fulfill the foregoing.

        14.2.16    If the Manager fails to adequately insure the project or
                   causes the insurance to fail then the Manager shall indemnify
                   and hold harmless the parties hereto and their directors,
                   officers, employees, agents and any other person to which a
                   party hereto has responsibility for all damages, costs,
                   injury, litigation, liability, indemnity, prosecution or any
                   other matter arising from the acts or omissions of the
                   Manager arising from willful acts or omissions or gross
                   negligence.

        14.2.17    The Manager shall not be in default of its duties if its
                   inability to perform results from the failure of the parties
                   to perform acts or to contribute funds, call or other amounts
                   required of them by this Agreement.

14.3    Standard of Care

        The Manager shall conduct all Operations in a good workmanlike and
        efficient manner, in accordance with sound mining and other applicable
        international industry standards and practices and shall operate in
        accordance with all applicable laws of Mali and in accordance with the
        terms and provisions of the Permits.

14.4    Resignation and Deemed Offer to Resign

        The Manager may resign as Manager of WAG at any time upon three month's
        prior written notice to the directors of WAG and Azco, or may be deemed
        to have resigned on the date of occurrence of the following, and in
        either case WAG shall elect a new Manager:

        14.4.1    where Randgold's shareholding in WAG is no longer the
                  largest; or

        14.4.2    the Manager, in that capacity, fails to perform a material
                  obligation imposed upon it under this Agreement and such
                  failure continues for a period of 60 days after notice from a
                  party demanding performance and the Manager has not disputed
                  the default, otherwise has been adjudged in default; or

        14.4.3    the Manager fails to pay the bills of WAG within 60 days after
                  they are due, provided such failure is not as a result of a
                  party failing to make part or all of the cash calls or other
                  contributions required of it under this Agreement; or

        14.4.4    the Manager suffers the appointment of a receiver, liquidator,
                  administrators, assignee, custodian, trustee, sequestrator or
                  similar official for a substantial part of its assets in a
                  proceeding brought against or initiated by it, and such

                                       18
<PAGE>   19

                   appointment is neither made ineffective nor discharged within
                   90 days after the making thereof or such appointment is
                   consented to, requested by or acquiesced in by it; or

14.4.5  the Manager:

        14.4.5.1   commences a voluntary case under any applicable bankruptcy,
                   insolvency or similar law now or hereafter in effect; or

        14.4.5.2   consents to the entry of an order of relief in an involuntary
                   case under any such law or to the appointment of or taking
                   possession by a receiver, liquidator, administrator,

                   official of any substantial part of its assets; or

        14.4.5.3   makes a general assignment for the benefit of creditors; or

        14.4.6     entry is made against the Manager of a judgment, decree or
                   order for relief by a court of competent jurisdiction in an
                   involuntary case commenced under any applicable bankruptcy,
                   insolvency or other similar law of any jurisdiction now or
                   hereafter in effect.

        14.4.7     in the event that Randgold is the majority shareholder but
                   has elected or failed to contribute to two or more quarterly
                   Budgets then Randgold may be replaced by the next largest
                   shareholder which is contributing to Budgets and wishes to be
                   Manager; or

        14.4.8     on termination of this Agreement.

14.5    Charges Levied by Manager

        14.5.1     The Manager shall be entitled to charge each month a
                   management fee equal to 5% of the funds expended in respect
                   of Operations on or relating to the Permit Areas during the
                   previous month.

        14.5.2     The management fee charged by the Manager under this clause
                   may be regarded for all purposes as part of the relevant
                   party's contribution to the minimum exploration expenditure
                   of $2 million which relates to the period during which the
                   charge is made.

        14.5.3     Nothing contained in this Agreement shall require the
                   Manager, in its capacity as such, to advance its own funds
                   for costs or expenses of the parties under this Agreement
                   except for the Manager's obligation to fund cost overruns as
                   contemplated in Article 11.

14.6    Transactions With Affiliates

        If the Manager engages Affiliates to provide services hereunder, it
        shall do so on terms no less favourable than would be the case with
        arm's length transactions.

                                   ARTICLE 15

                           FORMATION OF MINING COMPANY

15.1 After completion of a Bankable Feasibility Study, if the parties elect
to proceed with the

                                       19
<PAGE>   20

        development and if the law of Mali so requires, they shall form a mining
        company for that purpose. If the law of Mali does not require a new
        mining company then WAG shall continue as the mining company unless the
        parties mutually agree otherwise. The interest in the new mining company
        shall be held by WAG or, if the parties so elect, the new mining company
        shall allot to each of the parties the number of shares in accordance
        with their interests in WAG, adjusted for any dilution, and proportional
        in terms of the interest elected to be received by Mali as set forth
        below.

        15.1.1 Shareholding if Mali elects not to contribute towards Further
        Expenditure:

<TABLE>
<S>               <C>                       <C>
                  WAG                       85%

                  MALI                      15%
</TABLE>

        15.1.2 Shareholding if Mali contributes in full (5%) towards Further
        Expenditure:

<TABLE>
<S>               <C>                       <C>
                  WAG                       80%

                  MALI                    - 20%
</TABLE>


15.2    The mining company shall adopt a memorandum and articles of association
        in the form normally adopted at the relevant time by Malian mining
        companies unless the parties otherwise agree.

15.3    The mining company shall apply for an exploitation permit in its own
        name in respect of the Permit Areas or if that cannot be done, the
        parties shall jointly do so on behalf of the mining company.

15.4    Randgold will be appointed the first Manager and operator of the mining
        company on the same terms of this Agreement.

15.5    The Manager shall arrange financing for the development of a mine by the
        mining company. The intention of the parties is that external project
        finance be arranged to the maximum available. Any project financing
        shortfall shall be met by Randgold and Azco and if it elects to
        participate, by Mali, pro-rata to their shareholding in the mining
        company.

                                   ARTICLE 16

                             DISTRIBUTION OF PROFITS

16.1    All charges and expenses, as set forth in Part 13 regarding dilution
        which for the purposes hereof include exploration, operating,
        administration and depreciation costs incurred by Randgold and Azco on
        the Permit Areas up to the completion of the Bankable Feasibility Study,
        shall be considered as a loan by those parties to WAG.

16.2    The expenditure by Randgold and Azco up to the date of completion of the
        Bankable Feasibility Study will not bear interest. Expenses incurred
        after that date will bear monthly interest at the following rate:

        16.2.1     if the funds have been borrowed, the rate of interest must be
                   such as to cover the interest on the borrowed funds together
                   with all other costs associated with the loan;

        16.2.2     if the funds have not been borrowed, the interest rate must
                   be that which the

                                       20
<PAGE>   21

                   party's main bank will charge to its preferential clients,
                   on a non-guaranteed loan.

16.3    The above loans together with the interest shall be repaid to Azco and
        Randgold out of the proceeds of the sale of the product of the mine
        subject to cash being available in WAG as determined by the Manager on a
        reasonable basis after considering submissions from the parties.

16.4    The net after-tax profit of WAG, after setting aside sufficient for
        working capital and capital expenditure, shall be distributed in the
        following preferential order:

        16.4.1     to satisfy the obligations of the mining company to Mali;

        16.4.2     to repay loans from third parties in accordance with the
                   terms of such loan agreements;

        16.4.3     to pay interest on party loans, then to repay in the order in
                   which they were advanced the principal of non-interest
                   bearing loans as defined above to Randgold and Azco and
                   thereafter to pay principal on party loans ratably in
                   accordance with shareholdings;

        16.4.4     the balance to the parties in accordance with their
                   shareholding applicable at that time.

                                   ARTICLE 17

                              DISTRIBUTION OF CASH

17.1    All the cash available for payment of loans and distribution in
        accordance with Article 16.4 above, as at the last day of each quarter
        shall be distributed to the parties within 14 (fourteen) days after the
        end of such quarter in the proportions of their shareholding.

17.2    Should any difference arise between the parties as to the amount of cash
        available for distribution as at the last day of any quarter, the
        difference shall be determined by WAG's auditor or another party
        mutually selected to mediate.

                                   ARTICLE 18

                      CAMP EQUIPMENT AND DRILLING EQUIPMENT

18.1    Randgold has offered to buy from WAG or Azco (in accordance with their
        ownership) and Azco and WAG have accepted the offer, camp equipment and
        drilling equipment located at Dabia. Any proceeds WAG is to receive as
        an allocation of any part, or all, of the equipment, the parties agree
        shall be paid directly to Azco as a reduction of its loan to WAG. A copy
        of the offer and its acceptance is attached hereto as Schedule `6'. The
        basis of the sale is that the equipment is sold as is, and no
        representations are made as to its conditions and suitability, other
        than that no other party has any rights to the equipment, which is fully
        paid for.

18.2    Effective as of 13 October 1998 this equipment is the property of
        Randgold subject to execution of this Agreement.

18.3    Payment of the purchase price of US$277,500 will be made by Randgold to
        Azco within 90 days of the actual closing of the issue of WAG shares to
        Randgold, for the equipment and prices set forth in the enclosed
        Schedule "6".

19.1    Termination

        The parties may terminate this Agreement at any time by unanimous
        written agreement. Randgold shall be entitled to terminate this
        Agreement at any time until it has fully earned its Randgold Shares on
        the giving of 90 days' prior written notice to each other party and
        subject to all obligations arising from Randgold's operations as Manager
        and controlling shareholder of WAG shall have been discharged or Azco
        shall have been satisfied that sufficient security has been given for
        such discharge. However, termination shall not be effected in the time
        frame which is less than 180 days prior to the expiration of the Permits
        unless such shall be left in good standing adequate to renew the Permits
        in accordance with the terms of the Permits and Malian law. Termination
        shall be deemed to occur on the later of the last day of the notice
        period or the day that unfulfilled obligations are finally fulfilled.

19.2    Continuing Obligations

        Upon termination of this Agreement each party shall remain bound by and
        liable to satisfy, perform and fulfill their or its (as the case may be)
        obligations which are or were due to be satisfied, performed or
        fulfilled prior to the date of termination or withdrawal (as the case
        may be), and also any obligations which are expressed by this Agreement
        to survive termination or withdrawal (as the case may be).

19.3    Return of WAG Shares on Termination

        Promptly after termination the escrow agent shall be instructed by
        Randgold to deliver the Randgold Shares together with the transfer forms
        to Azco. Azco may then deal with or transfer the shares as it requires,
        at its cost. The Manager shall take all action necessary to wind up the
        activities of the operations and all costs and expenses incurred in
        connection with the termination of this Agreement shall be expenses
        chargeable to Randgold save for the share transfer fees.

19.4    Right to Data After Termination

        After termination of this Agreement each party shall be entitled to
        copies of all information acquired in connection with this Agreement as
        of the date of termination and not previously furnished to it.

        20.2.2     to be best of its knowledge and belief (having made all
                   reasonable inquiries):

                   20.2.2.1   no option, pre-emptive right, lease, prospecting
                              contract or other right or interest vested in any
                              third party exists in respect of the Permits,
                              which might restrict, prejudice, or in any way
                              detract from the rights conferred on Randgold
                              under this Agreement; and

                   20.2.2.1   there are no restrictions or limitations on
                              exploration or mining in or on the Permit Areas
                              other than the normal restrictions imposed by law
                              and the restrictions set out in the Permits;

        20.2.3     the Permits are in good standing at the Effective Date, and
                   remain in good standing as at the Implementation Date of this
                   Agreement;

        20.2.4     it has disclosed to Randgold all obligations that must be
                   fulfilled to keep the Permits in good standing during the
                   duration of this Agreement;

        20.2.5     it will, and it shall procure that its Affiliates will make
                   no further commitment to the Malian Ministry of Mines, or
                   other relevant mining authorities, or any other person, that
                   would affect the conditions required to be met to maintain
                   the Permits in good standing without first discussing and
                   agreeing those conditions and commitments with Randgold;

                   available to Randgold all data, records and other information
                   concerning title to, and all geological data relating to, the
                   Permits and the Permit Areas which was in its or its
                   Affiliates' possession or control as at the Effective Date or
                   which has since come into its or its Affiliates' possession
                   or control; and

        20.2.8     it has been entitled to, and shall continue to be entitled
                   to, deliver or make available to Randgold all data, records
                   and information of the type referred to in clause 20.2.7 and
                   that the data, records and information are, and shall be,

20.3    Azco Covenants

        Azco covenants and agrees as follows and each of these covenants shall

        20.3.1    Azco will assist, to the extent that it reasonably can and at
                  the cost of Randgold, the Manager in any aspects of
                  administration of title to the Permits which, because of the
                  operation of Malian law, regulation or practice, the Manager
                  is unable to fully perform or comply;

        20.3.2    without limitation to clause 20.3.1, at any time, and in any

                  efforts to assist the Manager in obtaining or maintaining the
                  Permits which are necessary to the conduct of Operations, and
                  it shall assist the Manager by informing the Manager of title
                  and mining problems or items which may affect the Permits;

        20.3.3    it shall make known and available to the Manager, its

                  from time to time pertaining to the Permits or pertaining to
                  the Permit Areas;

        20.3.4    it will not, unless expressly permitted by this Agreement,
                  enter into any agreement or arrangement, or purport to enter
                  into any agreement or arrangement, pursuant to which any third
                  party, entity or person would or may obtain any interest in,
                  or rights in respect of, the Permits, or any rights to
                  prospect, explore or mine in, or to evaluate or develop, the
                  Permit Areas.

        party the partner of the other parties or, except as otherwise herein
        expressly provided, to constitute a party the agent or legal
        representative of the other parties or to create any fiduciary
        relationship between the parties. It is not the intention of the parties
        to create, nor shall this Agreement be construed to create, any mining,
        commercial or other partnership. Neither parties shall have any

        without consulting the other, unless such competitive operation exists
        on the Implementation Date and has been disclosed. Neither party shall
        have any obligation to the other party with respect to any opportunity
        to acquire any property outside the Permit Areas at any time, except as

        from and against any liabilities which may be imposed upon, asserted
        against or incurred by any of them and which arise out of or result from
        any act or any assumption of liability by the indemnifying party, or any
        of its directors, officers, shareholders, employees, agents, attorneys
        and Affiliates, when such assumption is done or undertaken, or
        apparently done or undertaken, on behalf of the other parties or its

        nor any party, shall dispose of any interest in the Permits or the
        Permit Areas or any material Assets except if unanimously approved by
        the parties hereto or where required by law.

21.6    Employees

        not be regarded as, and shall not be held out to be, employees of the
        other parties.

        22.1.2     by electronic communication, with a confirmation sent by
                   registered or certified mail, return receipt requested. All

               22.1.2.2 if by electronic communication on the date of receipt of
                        the electronic communication. A party may change its

22.2    Waiver

        The failure of a party to insist on the strict performance of any
        provision of this Agreement or to exercise any right, power or remedy
        upon a breach hereof shall not constitute a waiver of any provision of
        this Agreement or limit the party's right thereafter to enforce any
        provision or exercise any right.

22.3    Modification

        No modification or amendment of this Agreement shall be valid unless
        made in writing and duly signed by the parties. If, in the event of
        experience gained through the operation of this Agreement, the parties
        agree that application of any of its provisions results in a material
        inequity to one or all of the parties, then the parties agree that they
        will meet to discuss possible changes in such provision(s) proposed by
        the parties as a means of obviating such inequity.

22.4    Force Majeure

        period that performance is prevented by any cause, whether foreseeable
        or unforeseeable, beyond its reasonable control, including, without
        limitation, labour disputes (however arising and whether or not employee
        demands are reasonable or within the power of the party to grant); acts
        of God; laws, regulations, orders, proclamations, instructions or
        requests of any government or governmental entity; judgments or orders

        possible.

                   this Agreement and shall also continue to apply for one year
                   following its termination, and shall continue to apply to a
                   party which forfeits, surrenders, assigns, transfers or
                   otherwise disposes of its shares for one year following the
                   date of such occurrence.

22.10   Default

        If a party defaults in the performance of any obligation under this
        Agreement or any provision of this Agreement (the "defaulting party"),
        each other party (the "non-defaulting party") may serve upon the
        defaulting party written notice of default. If the defaulting party
        within 30 (thirty) days following such notice does not cure the alleged
        default, the defaulting party shall be deemed to be in default of this

        rights and remedies which it has in respect of the default. Except as
        otherwise provided, the rights and remedies for default provided in this
        Agreement shall be in addition to, and not in lieu of, any other rights

               within the time periods specified in paragraph "2.2(b)".

2.5 TERMINATION BY THE OPTIONEE. Prior to the exercise of the Option the
Optionee may terminate the Option by providing a notice of termination to the
Optionor in writing of its desire to do so at least two calendar days prior to
its decision to do so. After such two calendar days' period the Optionee shall
have no further obligations, financial or otherwise, under this Agreement,
except that the provisions of section "2.7" hereinbelow shall become immediately
applicable to the Optionee upon providing the said notice of termination to the
Optionor.

or in the possession of the Optionee with respect to the mineral interests
comprising the Property and not theretofore already furnished to the Optionor.

the required Cash Payment and Trading Share issuance in accordance with section
"2.2" hereinabove, within the Option Period and the time periods as specified in
section "2.2", then the Option shall be deemed to have been exercised by the
Optionee, and the Optionee shall have thereby, in accordance with the terms and
conditions of this Agreement and without any further act required on its behalf,
acquired an undivided one hundred percent (100%) legal and beneficial interest
in and to the mineral property interests comprising the Property.

               contained in this section from being misleading or which would
               likely affect the decision of the Optionor to enter into this
               Agreement.

4.2 CONTINUITY OF THE REPRESENTATIONS, WARRANTIES AND COVENANTS BY THE OPTIONEE.
The representations, warranties and covenants of the Optionee contained in this

warranty or covenant of the Optionee contained herein caused by any act or

the Execution Date. In the event that any of the said representations,
warranties or covenants are found by a court of competent jurisdiction to be
incorrect and such incorrectness results in any loss or damage sustained
directly or indirectly by the Optionor, then the Optionee will pay the amount of
such loss or damage to the Optionor within 30 calendar days of receiving notice
of judgment therefor; provided, however, that the Optionor will not be entitled

10.1 CONFIDENTIAL INFORMATION. Each Party hereto acknowledges that any and all
information which a Party may obtain from, or have disclosed to it, about the
other Parties constitutes valuable trade secrets and proprietary confidential
information of the other Parties (collectively, the "Confidential Information").
No such Confidential Information shall be published by any Party without the
prior written consent of the other Parties hereto; however, such consent in
respect of the reporting of factual data shall not be unreasonably withheld and
shall not be withheld in respect of information required to be publicly
disclosed pursuant to applicable securities or corporation laws. Furthermore,
each Party hereto undertakes not to disclose the Confidential Information to any
third party without the prior written approval of the other Parties hereto and
to ensure that any third party to which the Confidential Information is
disclosed shall execute an agreement and undertaking on the same terms as
contained herein.

10.2 IMPACT OF BREACH OF CONFIDENTIALITY. The Parties hereto acknowledge and
agree that the Confidential Information is important to the respective
businesses of each of the Parties and that, in the event of disclosure of the
Confidential Information, except as authorized hereunder, the damage to each of
the Parties hereto, or to either of them, may be irreparable. For the purposes
of the foregoing sections the Parties recognize and hereby agree that a breach
by any of the Parties of any of the covenants therein contained would result in
irreparable harm and significant damage to each of the other Parties that would
not be adequately compensated for by monetary award. Accordingly, the Parties
agree that in the event of any such breach, in addition to being entitled as a
matter of right to apply to a court of competent equitable jurisdiction for
relief by way of restraining order, injunction, decree or otherwise as may be
appropriate to ensure compliance with the provisions hereof, any such Party will
also be liable to the other Parties, as liquidated damages, for an amount equal
to the amount received and earned by such Party as a result of and with respect
to any such breach. The Parties also acknowledge and agree that if any of the
aforesaid restrictions, activities, obligations or periods are considered by a
court of competent jurisdiction as being unreasonable, the Parties agree that
said court shall have authority to limit such restrictions, activities or
periods as the court deems proper in the circumstances. In addition, the Parties
further acknowledge and agree that all restrictions or obligations in this
Agreement are necessary and fundamental to the protection of the respective
businesses of each of the Parties and are reasonable and valid, and all defenses
to the strict enforcement thereof by either of the Parties are hereby waived by
the other Parties.

(the "Purchaser's Notice of Termination") at least 10 calendar days prior to the
effective date of any such termination (the "Effective Termination Date"). In
any such event the respective obligations of each of Parties hereto under this

the Shareholder during such four year term and, thereafter, transfer to the
Shareholder for the sum of U.S. $1.00; it being acknowledged and agreed that the

               Sales of at least U.S. $600,000 during each of such four
               additional months and, in addition, during each of which
               additional four months a similar Profit Margin of at least twenty
               percent (20%) was maintained by either the Purchaser, its
               subsidiary or its Trading Subsidiary, as the case may be, in

               Issuance"); and

        (c)    subject to the prior obligation and completion of each of the
               Initial Performance Share Issuance and the Second Performance
               Share Issuance under the conditions and during the initial five
               month and additional four month periods as contemplated in
               paragraphs "3.4(a)" and "3.4(b)" hereinabove, the final 250,000

               which either the Purchaser, its subsidiary or its Trading
               Subsidiary, as the case may be, maintained Gross Sales of at
               least U.S. $800,000 during each of such three additional months
               and, in addition, during each of which additional three months a
               similar Profit Margin of at least twenty percent (20%) was
               maintained by either the Purchaser, its subsidiary or its Trading
               Subsidiary, as the case may be, in respect of such Gross Sales.

3.5 CALCULATION AND COLLECTION OF GROSS SALES. It is hereby acknowledged and
agreed that the Royalty shall be accounted for monthly, and within 30 calendar
days after the end of each such month, and that the first month shall commence
on the first business day of the month following the month of the Effective Date
hereof. The Royalty shall be calculated on all amounts invoiced, or deemed
invoiced, in a month. Within 30 calendar days (or such extended time as the
Parties may permit) of the end of each month the Purchaser, its subsidiary or
its Trading Subsidiary, as the case may be, shall be required to render a
monthly accounting statement with explanatory notes, shall make any adjustments
thereto and shall calculate any Royalty due from such adjustment upon
presentation of such accounting or give notice of any deduction to be carried to
apply to Gross Sales for the next month. The calculation of Gross Sales shall be
carried out in accordance with generally accepted United States accounting
principles applied on a consistent basis. In this regard the Vendors may contest
any accounting within 15 calendar days of presentation of such report. However,
an accounting may be challenged at any time if it comes to the attention of the
Vendors that the Purchaser has failed to clearly disclose any material fact or
Gross Sale therein. It will be the responsibility of the Purchaser, its
subsidiary or its Trading Subsidiary, as the case may be, to collect the amounts
of Gross Sales and all risk of such shall be that of the Purchaser.
Notwithstanding that the Purchaser shall not have invoiced a customer, it shall
be deemed to have invoiced for all Product on the tenth calendar day after
delivery of the same unless special circumstances, with prior approval in
writing by the Vendors, pertain. However, the Purchaser may deduct from Gross
Sales upon which a Royalty is calculated the uncollected receivables from
preceding months which the Purchaser has made bona fide and reasonable best
efforts to collect, but the cost of collection shall not be deducted from Gross
Sales for the purpose of any Royalty calculation. All calculated Gross Sales
figures shall be made in U.S. dollars without any reduction or deduction of any
nature or kind whatsoever, except as set forth in this Agreement. In this regard
the Purchaser shall not exercise any set-off, deduction or any other reduction
to the Gross Sales whether for claims of damages, costs or any other amount
excepting only the uncollected receivables as set forth hereinabove. In the
event that there is any dispute about the calculation or deductibility of
uncollected receivables, such shall be determined by arbitration in accordance
with Article "17" hereinbelow.

                                    ARTICLE 4

                   INTERIM SECURED LOAN AND SECURITY THEREFORE

4.1 INTERIM SECURED LOAN FROM THE PURCHASER TO THE VENDORS. In conjunction with
and as a condition to the entering into of this Agreement by the Parties hereto,
and prior to the Closing (as hereinafter determined) the Purchaser has agreed to
hereby advance by way of a loan or loans to the Vendors (collectively,

                                      -7-
<PAGE>   8

the "Principal Sum"), together with interest accruing thereon at the rate of ten

Purchaser and the Vendors prior to the advancement of any such Loan, and which
Principal Sum and Interest will be secured, contemporaneously with the
advancement of any funds under any such Loan, by way of a senior fixed and
floating charge on all of the assets of the Vendors (collectively, the
"Security"). In this regard it is hereby acknowledged and agreed that, upon the
completion of the within purchase and sale, it is intended, subject to the
Purchaser's prior receipt of appropriate accounting and legal advice, that the
Loan will simply be forgiven or become an inter-company account as the situation
may require.

in any way by any other contract or agreement between the Parties hereto whether

duty, liability and responsibility shall be to hold and deal with the Transfer
Documents as herein directed. The Escrow Agent shall be entitled to assume that

                DUE DILIGENCE, NON-DISCLOSURE AND CONFIDENTIALITY

8.1 DUE DILIGENCE. Each of the Parties hereto may conduct such further due
diligence examination of the other Parties hereto as it deems appropriate. Each
Party may in a reasonable manner carry out such investigations and due diligence
as to the other Parties hereto, at all times subject to the confidentiality
provisions hereinbelow, as each Party deems advisable. In that regard the
Parties agree that each shall have full and complete access to the other
Parties' books, records, financial statements and other documents, articles of
incorporation, by-laws, minutes of Board of Directors' meetings and its
committees, investment agreements, material contracts and as well such other
documents and materials as the Parties hereto, or their respective counsel, may
deem reasonable and necessary to conduct an adequate due diligence investigation
of each Party, its respective operations and financial condition prior to the
Closing.

8.2 NON-DISCLOSURE. Subject to the provisions of hereinbelow, the Parties
hereto, for themselves, their officers, directors, shareholders, consultants,
employees and agents, agree that they each will not disseminate or disclose, or
knowingly allow, permit or cause others to disseminate or disclose to third
parties who are not subject to express or implied covenants of confidentiality,
without the other Parties' express written consent, either: (i) the fact or
existence of this Agreement or discussions and/or negotiations between them
involving, inter alia, possible business transactions; (ii) the possible
substance or content of those discussions; (iii) the possible terms and
conditions of any proposed transaction; (iv) any statements or representations
(whether verbal or written) made by either Party in the course of or in
connection with those discussions; or (v) any written material generated by or
on behalf of any Party and such contacts, other than such disclosure as may be

                                      -14-
<PAGE>   15

generated by either Party hereto in the course of, or in connection with, the
due diligence investigations conducted pursuant to this Agreement shall be
marked "Confidential" and shall be treated by each Party as a trade secret of
the other Parties. Upon termination of this Agreement prior to Closing all
copies of any and all documents obtained by any Party from any other Party
herein, whether or not marked "Confidential", shall be returned to the other
Parties forthwith. Notwithstanding the provisions of this Article, the Parties
hereto agree to make such public announcements of this Agreement promptly upon
its execution in accordance with the requirements of applicable securities
legislation and regulations.

8.3 CONFIDENTIAL INFORMATION. Each Party hereto acknowledges that any and all
information which a Party may obtain from, or have disclosed to it, about the
other Parties constitutes valuable trade secrets and proprietary confidential
information of the other Parties (collectively, the "Confidential Information").
No such Confidential Information shall be published by any Party without the
prior written consent of the other Parties hereto, however, such consent in
respect of the reporting of factual data shall not be unreasonably withheld, and
shall not be withheld in respect of information required to be publicly
disclosed pursuant to applicable securities or corporation laws. Furthermore,
each Party hereto undertakes not to disclose the Confidential Information to any
third party without the prior written approval of the other Parties and to
ensure that any third party to which the Confidential Information is disclosed
shall execute an agreement and undertaking on the same terms as contained
herein. The Parties hereto acknowledge that the Confidential Information is
important to the respective businesses of each of the Parties and that, in the
event of disclosure of the Confidential Information, except as authorized
hereunder, the damage to each of the Parties hereto, or to either of them, may
be irreparable. For the purposes of the foregoing sections the Parties recognize
and hereby agree that a breach by any of the Parties of any of the covenants
therein contained would result in irreparable harm and significant damage to
each of the other Parties that would not be adequately compensated for by
monetary award. Accordingly, the Parties agree that in the event of any such
breach, in addition to being entitled as a matter of right to apply to a Court
of competent equitable jurisdiction for relief by way of restraining order,
injunction, decree or otherwise as may be appropriate to ensure compliance with
the provisions hereof, any such Party will also be liable to the other Parties,
as liquidated damages, for an amount equal to the amount received and earned by
such Party as a result of and with respect to any such breach. The Parties also
acknowledge and agree that if any of the aforesaid restrictions, activities,
obligations or periods are considered by a court of competent jurisdiction as
being unreasonable, the Parties agree that said court shall have authority to
limit such restrictions, activities or periods as the court deems proper in the
circumstances. In addition, the Parties further acknowledge and agree that all
restrictions or obligations in this Agreement are necessary and fundamental to
the protection of the respective businesses of each of the Parties and are
reasonable and valid, and all defenses to the strict enforcement thereof by
either of the Parties are hereby waived by the other Parties.

                                    ARTICLE 9

                                   ARBITRATION

receiving notice of the appointment of the first arbitrator, or if the two
arbitrators appointed by the Parties shall be unable to agree on the appointment
of the chairman, the chairman shall be appointed under the provisions of the

Parties, and he shall preside over the arbitration and determine all questions

The expense of the arbitration shall be paid as specified in the award. The
Parties hereto agree that the award of a majority of the arbitrators, or in the
case of a single arbitrator, of such arbitrator, shall be final and binding upon
each of them.
