Item 1. BUSINESS
        --------


GENERAL
- -------

Atlas Corporation ("Atlas" or "the Company") is a New York Stock Exchange listed
mining company (AZ:NYSE) which is principally engaged in the exploration,
development and exploitation of mineral resource properties.  Atlas was
incorporated under the laws of the State of Delaware on October 31, 1936.  The
principal office of Atlas is located at Republic Plaza, 370 Seventeenth Street,
Suite 3050, Denver, Colorado, 80202 USA.  Atlas has five subsidiaries: (i) Atlas
Precious Metals Inc. ("APMI"), incorporated under the laws of the State of
Nevada, which holds the Grassy Mountain property and the exploration portion of
the Gold Bar claim block, (ii) Atlas Gold Mining Inc. ("AGMI"), incorporated
under the laws of the State of Nevada, which holds the mineral reserves and
other assets and infrastructure at the Gold Bar mine, (iii) 50% ownership in
Arisur Inc., ("Arisur"), a Grand Cayman corporation, which owns and operates
mines in Bolivia, South America through a Bolivian branch (iv) Suramco Metals,
Inc. ("Suramco"), a Nevada Corporation which holds the remaining 50% interest in
Arisur amd (v) Cornerstone Industrial Minerals Corporation ("Cornerstone")
(formerly known as Phoenix Financial Holdings,Inc.).  Atlas intends to wind up
the businesses of APMI, AGMI, and Suramco, as soon as practicable, as a means to
cut its General and Administrative costs.  In December 1996 Atlas completed the
sale of its wholly-owned subsidiary, Atlas Perlite, Inc., to Cornerstone.  See
"Item 1 Business - Tucker Hill".  As a result of the sale, Atlas will ultimately
hold a 65% interest in Cornerstone.  In addition the Company holds a 9.6%
interest in Vista Gold Corp. (successor of Granges Inc. and Da Capo Resources
Ltd. amalgamation in October 1996 "Vista") See "Item. 1 Business - Investments".
                                                        ----------------------  

ARISUR INC.
- -----------

On October 8, 1996 the Company acquired Arisur which owns and operates the
Andacaba and Don Francisco underground lead, zinc and silver mines located in
southern Bolivia.  The Company acquired a 50% interest in Arisur from Arimetco
International Inc., a Canadian corporation, for $3 million in cash and purchased
100% of Suramco, which owns the remaining 50% interest in Arisur, for four
million shares of the Company's common stock.  In addition, in November 1996
Arisur acquired the Koyamayu mine and the Comali mill.

EMPLOYEES AND OFFICES

Arisur's corporate offices are located in La Paz and staffed by seven persons.
Operations are conducted out of Arisur's office in Potosi which is staffed by
eleven persons.  Additionally, there are 160 miners and 38 mill workers who are
directly involved in operations at Andacaba, Don Francisco and Koyamayu.

                                       3

ANDACABA  MINE
- --------------

LOCATION

The property is located in the south central altiplano region of Bolivia near
the city of Potosi, a historic mining community, at an altitude of approximately
4,500 meters (14,800 feet).  The Andacaba property is accessible by traveling
south/southeast 37 kilometers (23 miles) via an all weather gravel road from the
city of Potosi.

PROPERTY

The Andacaba mine and facilities are situated on 19 concessions controlled 100%
by Arisur comprising 3,000 hectares (7,400 acres).

OPERATIONS

The Andacaba lead, zinc and silver mine has been in operation since the early
1900s.  The mining operations take place year round on the basis of 28 days per
month for a total of 330 work days per year.  The two operating mills on site
are the Don Roy mill which processes Andacaba ore and the Don Max mill which
processes other ores and performs custom milling.  The concentrates are shipped
by truck to Potosi and then by rail to warehouses the Chilean seaports
(Antofagasta for the zinc-silver concentrates and Arica for the lead-silver
concentrates), prior to shipment to smelters in various markets.

CONDITION

Service facilities at the mine site are basic and require upgrading as part of
the mine and mill expansion underway. Don Roy mill capacity is being upgraded
and expanded to 600 tonnes per day (662 short tons).  Surplus equipment from the
Don Roy mill will be used to upgrade the Don Max mill to a rate of 200 tonnes
(221 short tons) per day. Power is currently supplied by a 1,500 kilowatt
substation.  An electrification program is underway to upgrade power for the
mine and mill expansion.  Water for the mills is supplied by mine drainage.
Ample water and power for the current mill size are available at the site.  The
city of Potosi provides a source of supplies and labor.

GEOLOGY/MINERALOGY

The mineralized veins at Andacaba are enclosed in tertiary porphyritic quartz
latite or rhyodacite volcanic rocks.  The volcanics are part of an igneous
complex that includes an elliptical-shaped pluton of biotite granodiorite that
crops out south of the mine area.  The pluton is believed to be 40 kilometers
(25 miles) long and 14 kilometers (9 miles) wide. Volcanic breccias can be
observed in the mine area.  Clasts in the breccias consist of sediments and
volcanics that range from one to 15 centimeters (0.4 to 6 inches) across.  The
matrix is fine, pulverized material cemented by quartz.  Paleozoic sediments
outcrop west of 

                                       4
<PAGE>
 
the mine and lead, zinc and silver veins are known to occur in the sediments
beyond the property boundary. The thickness of the volcanic package is not known
and at deeper levels in the mine the host volcanics may change to either
Paleozoic sediments or possibly granodiorite. On the surface the veins are
oxidized to a depth of about 20 meters (66 feet). Minerals in the oxidized zone
include limonite, hematite, goethite, quartz and clay. In the sulfide zone the
primary minerals are marmatite, galena, jamesonite, boulangerite, sphalerite,
tetrahedrite, stephanite, quartz, pyrite, pyrrhotite, chalcopyrite,
arsenopyrite, siderite, and others. Wall rocks show very little alteration.
There is possibly some silicification of the rhyodacite.

  Prospective resources of 7 million tonnes (7.7 million short tons) are
inferred based on geological projections.


DON FRANCISCO MINE
- ------------------

LOCATION

The property is accessible via an all weather road 77 kilometers (48 miles) in a
southerly direction from Potosi or 64 kilometers (40 miles) from the Andacaba
mine.  The Don Francisco mine is at an altitude of 3,000 meters (9,800 feet).

PROPERTY

Arisur owns four concessions covering 350 hectares (approximately 865 acres).

OPERATIONS

The Don Francisco mine, which is presently undergoing an underground development
program, is producing approximately 80 tonnes (88 short tons) per day.
Production is scheduled to increase to 100 tonnes (110 short tons) per day in
1997 and 200 tonnes (221 short tons) per day in 1998. There is no mill onsite
and ore is trucked to Andacaba for processing at the Don Max mill.
Alternatively, the ore may be trucked to the recently acquired Comali

                                       5
<PAGE>
 
mill, as described below, located near the town of Toropalca to the south. The
Company intends to use the Comali mill as a regional mill and may utilize it to
toll ore for third parties.

CONDITIONS

Sufficient water is available to conduct the mining operations.  Electrical
power is presently supplied by generator but the construction of a power line to
the project is planned for late 1997 or early 1998.  A camp is situated on the
property for the mine workers and a radio communication system is in place
between the Don Francisco and the Andacaba mines.

GEOLOGY

The structural setting is similar to Andacaba in that there is one main
structure - the Veta Principal south of the river which flows across the
property, and the Veta Cumbre north of the river with secondary splits off the
footwall of the main vein.  Host rocks are Ordovician calcareous shales,
siltstones and sandstones.  The sequence has been folded into a series of
synclines and anticlines.  The Veta Principal occupies both flanks and the axial
portion (for a short distance) of a major anticline.  Igneous dikes are also
present in the stratigraphic section.

KOYAMAYU MINE

In January 1997 the Company acquired the Koyamayu  lead, zinc and silver
property, located in southern Bolivia, for $100,000.  The Company is currently
developing a mine plan to confirm mineralization and expects to place the
property into production during the second half of 1997.  The ore mined at
Koyamayu will be processed at the Andacaba mine or alternatively at the Comali
mill.

                                       6
<PAGE>
 
COMALI MILL

The Comali mill was acquired in late 1996 by Arisur for $140,000.  Its current
operational capacity is 120 tonnes (130 short tons) per day.  Its circuits
recover lead, zinc and silver.  The Comali mill is situated near the community
of Toropalca, 30 kilometers (19 miles) south of Don Francisco.

                     ____________________________________

In Bolivia, the Company's near-term focus will be on expansion of existing
operations, the evaluation of additional lead, zinc and silver mining
opportunities and evaluation of precious metal opportunities.

CORNERSTONE INDUSTRIAL MINERALS CORPORATION
- -------------------------------------------

On November 30, 1995, the Company purchased from a group of individual investors
12.2 million shares of Phoenix Financial Holdings Inc., representing
approximately 51% of total shares outstanding for an aggregate purchase price of
C$1,781,200.  On September 3, 1996 the shareholders approved a name change from
Phoenix Financial Holdings Inc. to Cornerstone Industrial Minerals Corporation
("Cornerstone").  On December 13, 1996 Cornerstone executed a Stock Purchase
Agreement providing for the purchase by Cornerstone of all of the issued and
outstanding shares of Atlas Perlite, Inc., owner of the Tucker Hill perlite
Project (Tucker Hill) and a wholly-owned subsidiary of Atlas.  Subsequently,
Cornerstone changed the name of Atlas Perlite, Inc. to Cornerstone Industrial
Minerals Corporation, USA.  The Stock Purchase Agreement calls for payment to
Atlas of $1 million in cash, the issuance of 9,647,986 shares of common stock of
Cornerstone, valued at $1 million, the reimbursement of Atlas's Tucker Hill
development costs of $2,945,282, and the retention by Atlas of a 2% gross
proceeds royalty generated from the sale of perlite from Tucker Hill.  The
purchase price is payable in three stages as follows: $125,000 and 1,205,998
shares due at closing, $500,000 and 4,823,993 shares of common stock upon
obtaining all operating permits and $375,000 and 3,077,994 shares of common
stock related to Atlas assisting the Company in meeting three other milestones
which include obtaining base load perlite contracts for a specified amount of
revenues per year, obtaining permanent project financing and achieving
commercial production. The additional shares will result in Atlas's equity
position in Cornerstone increasing from approximately 51% to 65%.  The
transaction was approved by a committtee of independent board members of
Cornerstone and also was approved by a majority of the minority shareholders of
Cornerstone at its annual general meeting held on September 3, 1996.

TUCKER HILL OPERATIONS
- ----------------------

Cornerstone will produce and process perlite for sale to end users.  Operations
are directed through Cornerstone's Lakeview, Oregon office which will be staffed
by fifteen persons.  Cornerstone's Corporate offices are located in Denver,
Colorado.

Perlite is a naturally-occurring volcanic glass which is environmentally
friendly and chemically inert.  Expanded, perlite's heat resistance,
extraordinary insulating characteristics and low bulk 

                                       7
<PAGE>
 
density suit it ideally for wide application in construction, horticulture and
industry. Other uses for expanded perlite include filter media for
pharmaceuticals, food products and chemicals. Natural perlite, when subjected to
heat, physically expands to up to twenty times its original volume. This
expansion is due to the change in the state of water (2% to 5%) entrapped within
the glass structure. As this interstitial water turns to vapor, the internal
pressures increase and the perlite expands into larger, less dense particles.
Cornerstone mines, crushes, sizes, and delivers finished perlite meeting various
quality specifications to end users (expansion plants).

In 1997 demand for finished perlite in the United States is expected to exceed
700,000 tons. Demand growth averaged 6% per year from 1985 to 1994 and was 9% in
1995.  Cornerstone expects to take advantage of its regional location for sales,
including sales to customers in Canada and Pacific rim countries.

Location

The Tucker Hill project is comprised of a quarry, a processing facility and a
transloading facility, all located in south-central Oregon.  The quarry is
accessed by traveling 35 miles northwest of the community of Lakeview, in Lake
County, Oregon on US Highway 395 and State Highway 31, and then three and a half
miles south on an improved haulroad.  The processing facility is located in an
industrial park in Lakeview.  The transloading facility, comprised of silos for
product storage and load-out access to a rail spur, is located 90 miles west of
Lakeview in Henley, Oregon.

Property

The Tucker Hill property encompasses approximately 900 acres and is comprised of
45 unpatented lode mining claims.  The millsite property, comprised of 25 acres
of fee land, was purchased by Cornerstone from Lake County.  Finally, the
transloading facility located in Henley is situated upon property held under a
long term lease from the Burlington Northern Santa Fe Railway, owner and
operator of the rail spur adjacent to this facility.

Geology

Tucker Hill is a low hill with about 500 feet of relief within the Chewaucan
Valley.  The perlite deposit occurs in the northeastern portion of the Devils
Garden lava field.  The lava field is five to ten million years old and is thus
classified as late Miocene to early Pliocene and is composed largely of olivine
basalt flows, minor andesite flows, and related rhyolitic domes and pyroclastic
rocks.  Tucker Hill is one of the late miocene composite rhyolitic lava domes
within the field.  The Tucker Hill rhyolitic dome complex is a package of
cooling units that originated from a single eruptive center along a linear vent
system.  Two major cooling units are recognized: the outer chill margin and
inner rhyolitic core.  The chill margin consists of an outer glass envelope and
contains various sub-units of perlite.  Erosion of the Tucker Hill lava dome has
removed a significant portion of the outer glass envelope, exposing the
rhyolitic core.  Extensive areas of perlite remain.

                                       8

History

A small portion of the Tucker Hill perlite deposit was discovered by local
Oregon prospectors in 1949.  Bulk samples taken by these prospectors were
collected and crudely expanded by the US Bureau of Mines in Tucson, Arizona.
Expansion results were favorable and the property underwent a brief period of
surface mining.

In 1980, Houston International Minerals Corporation, later acquired by Tenneco
Inc. acquired the property through location of mining claims and confirmed the
presence of a significant resource of commercial grade perlite.  In July 1987
Atlas acquired an option to purchase this property from Tenneco Inc., which was
exercised in 1988.

Extensive evaluation work was carried out by Tenneco Inc. consisting of
geological mapping, rock chip sampling and analysis, diamond core drilling and
bulk sampling.  Atlas continued this effort and, to date, 42 holes have been
drilled and numerous surface bulk samples collected. Testing of the perlite
included expansion tests, measurements of expanded and compacted density,
sinkers (percentage of non-expandables) and brightness.  Full scale testing of
bulk samples was performed at the facilities of two end users.  The results of
this test work indicated that Tucker Hill perlite exceeded established standards
for expansion and yield.

In 1995, Atlas made the decision to develop Tucker Hill and has subsequently
acquired the necessary operating permits.  Construction of the processing
facility will be completed in 1997, making the facility operational on a
commercial basis.  A significant contract for over 40,000 tons per year has been
executed with Armstrong World Industries, Inc. ("Armstrong") and Cornerstone
continues its efforts to contract with other purchasers for finished perlite.

Reserves

Proven and probable reserves at Tucker Hill of 4.9 million tons of perlite were,
reported by Micon International Limited in its "Review of The Tucker Hill
Perlite Deposit" completed on April 26, 1996.  The report was prepared at the
direction of a special independent committee of the Cornerstone Board of
Directors, in support of Cornerstone's purchase of Atlas Perlite, Inc.

The 4.9 million tons is based on 42 core and reverse circulation drill holes and
13 bulk samples. Samples were analyzed for chemical, physical, an optical
characteristics as well as expandability performance.  Test results demonstrate
that the perlite is a universal variety suitable for a wide array of expanded
products.

The reserves are restricted to an area delimited by the ten year mining plan as
permitted with the Bureau of Land Management. Geologic resources have been
estimated in excess of 50 million tons.

Operations

Mining
- ------

Cornerstone conducts mining utilizing conventional quarrying methods.  Topsoil
and organic matter are stripped from the surface with a dozer to expose the
perlite.  This material is stockpiled for later use as growth media during
reclamation.  The perlite is then ripped and cross-ripped with the dozer to a
depth of about two feet.  This procedure provides the quality control necessary
for production of perlite containing minimal contaminants such as obsidian or
clay.

The perlite loosened by ripping is gathered into a pile with the dozer and
loaded into trucks with a loader.  A contract trucking company then hauls the
perlite to the processing facility in Lakeview where it is dumped onto the run-
of-mine stockpile.  Internal waste, which is minimal (approximately five
percent), will be hauled to a gravel pit at the base of Tucker Hill for
disposal.

Processing
- ----------

Finished perlite is produced from the processing facility, a crushing, drying
and sizing operation, in four product streams.  Run of mine perlite is reclaimed
from the mill stockpile with a loader and is then dumped into a pocket feeding a
primary jaw crusher.  This jaw crusher reduces the size of the perlite to about
two inches.  This crushed perlite reports to a crushed ore stockpile for
delivery to a secondary impact crusher where it is further reduced in size to
1/2 inch and is then dried in a rotary drier.  The purpose of drying is to
deliver a product to end users which has less than 0.5 percent free moisture, a
requirement for most end users.

After drying, the product reports to a primary screen where horticultural grade
perlite is separated.  Undersize perlite which passes the primary screen reports
to the secondary screens, with oversize being crushed by a tertiary impact
crusher, in closed circuit with the secondary screens.  Filler/insulation grade
perlite is obtained from the secondary screen undersize.  An extensive dust
collection system recovers fines from all transfer points downstream from the
dryer.  These fines are classified by cyclones thereby creating two additional
finished fine perlite grades.

Finally, the sized perlite is stored at this facility in silos with the finished
product being delivered to customers via rail or by truck.  The Lakeview plant
site is situated on a rail line which is serviced by the Union Pacific Railroad.

Transloading Facility
- ---------------------

In order to ensure rail access and to gain a competitive advantage for rail
transportation rates, Cornerstone has constructed a transloading facility at
Henley which is serviced by the Burlington Northern Santa Fe Railway.  Finished
perlite from the Lakeview plant will be hauled by a trucking contractor to
Henley and off-loaded into silos for transloading into rail cars.

                                      10
<PAGE>
 
Environmental Permitting

Cornerstone acquired the key regulatory permits for its quarry operations
through the Bureau of Land Management and Oregon Department of Geology and
Mineral Industries. Operation of the Lakeview plant is permitted under a
conditional use permit granted by Lake County and a permit granted from the
Oregon Department of Environmental Quality.

Project Status

Initial mining operations commenced at the quarry in December 1996.  As detailed
above, Cornerstone mines the quarry and a contractor is used for hauling perlite
to the Lakeview plant. The same contractor will haul finished perlite from the
Lakeview plant to the transloading facility at Henley. Testing of the processing
facility began in February 1997 at the Lakeview plant which is operated by
Cornerstone. Initial shipments of finished perlite have been made to Armstrong
which has reported that the perlite is satisfactory for its operations. The
facility is currently undergoing modifications identified in the testing phase.
Contract deliveries to Armstrong are expected to begin in the summer of 1997.

Cornerstone has a contract with Armstrong to supply Armstrong's St. Helens,
Oregon facility with all of its perlite requirements, currently estimated to be
approximately 55,000 tons per year. The initial term of the contract is for
three years and provides for a two year extension if rates are agreed.
Cornerstone is seeking to put in place additional contracts for the sale of
finished perlite. It is expected that sales in 1997 will achieve a rate of 5,000
tons per month.  The Lakeview plant has a permitted capacity of 100,000 tons per
year.  Prices are negotiated with end users and are partially a function of
transportation costs.

GRASSY MOUNTAIN PROPERTY
- ------------------------

LOCATION

The Grassy Mountain project is located in northern Malheur County, Oregon,
approximately 22 miles southwest of Vale, Oregon.  The property is accessed by
traveling four miles west from Vale on US Highway 20, then south on the Twin
Springs County Road for 23 miles, or by driving south from Nyssa on US Highway
95 to Owyhee and then west to Rock Springs Canyon and by gravel road for 14
miles.  The project elevation ranges from 3,300 to 4,300 feet.

PROPERTY

The Grassy Mountain property encompasses approximately 23 square miles.  Atlas
owns 611 unpatented lode claims.  An additional 119 unpatented lode and placer
claims are controlled under five separate mineral lease or lease/option to
purchase agreements.  Approximately 1,000 acres of fee surface, 240 acres of fee
surface and minerals, and 80 acres of fee minerals are held by two lease/option
agreements.  Atlas holds one state prospecting permit covering 1,280 acres.

                                      11

Geology

The rocks exposed at Grassy Mountain are part of a late to middle-Miocene Grassy
Mountain Formation, a sequence of volcanic and volcanisclastic rocks made up of
primarily olivine-rich basalt and intercalated tufaceous siltstones, sandstones,
and conglomerates.  The rocks have been dated through mammalian fossils and
Potassium Argon chronology to be approximately 10 million years old.  The
sediments are primarily flat-lying with a slight regional dip to the east. The
structural trend of the area is N10W to N30E.  These features were probably cut
by later post-mineralization east-west faulting.

Mineralization is associated with a low grade gold siliceous hot springs system
with enrichment along multi-stage quartz-adularia veins and favorable
lithologies.  Explosive brecciation and overpressuring of the rock, common in
these systems, was minimized due to the un-lithified nature of the sediments.
The mineralized rock is highly silicified and locally brecciated in the vicinity
of the feeder structures.  As silicification decreases so does grade.  Away from
the feeder zones lithology also plays an important role in gold deposition.  The
finer grained siltstones contain the bulk of the lower grade material.  The
higher grades are found in the coarser arkosic sandstones.  The feeder or vein
zones contain grades as high as 20 ounces of gold/ton ("oz. Au/t").

HISTORY

There was no significant mining or major mineral occurrence known in the area
prior to the Company's acquisition of the Grassy Mountain deposit in 1986.

Detailed mapping and sampling were completed in 1986 and several drill targets
were defined.  Hole 26-9 is considered the discovery hole with 145 feet of
mineralization averaging 0.075 oz. Au/t.  The claim block was expanded at this
time and exploration work continued through 1991.  The Company completed 388
drill holes for a total of approximately 221,500 feet on the property.

Newmont Grassy Mountain Corporation, a wholly owned subsidiary of Newmont
Exploration Company ("Newmont"), acquired the property from the Company in
September, 1992 and continued property evaluation through August, 1994
completing an additional 13 core and reverse circulation holes.

In September 1996 the Company executed an agreement with Newmont, (the
"Agreement"), which provided for the reconveyance of the Grassy Mountain
property to the Company. Pursuant to the Agreement, Atlas paid an amount of
$206,000 to Newmont, issued a $500,000 unsecured, non-interest bearing
promissory note due September 18, 1997 and assumed bonding requirements for
exploration reclamation of $146,000.

RESERVES

As part of a detailed feasibility study conducted by Kilborn SNC-Lavin, Inc.
("Kilborn") in 1990, an open pit mine model was developed by Pincock, Allen &
Holt, Inc.  The feasibility study resulted in the definition of a mineable
reserve of 996,000 ounces at a $350 gold price from 

                                      12
<PAGE>
 
16 million tons at grades 0.062 oz. Au/t of mill and heap leach ores. Neither
the recovered silver nor low grade leach ores were considered. The contained
silver is approximately 2,467,000 ounces.

A feasibility study was completed in 1990 by Pincock, Allen & Holt, Inc.  The
database utilized for this study consisted of 180 drill holes in the main
deposit area.  The drilling is predominantly vertical and angle reverse
circulation rotary drill holes with some core holes.  Using a 0.02 oz. Au/t
cutoff, Pincock, Allen & Holt, Inc. calculated a geologic resource of 17,217,000
tons at a grade of 0.061 oz. Au/t for a total of 1,051,500 ounces and 2,610,000
ounces of contained silver.

UNDERGROUND STUDY

Two underground feasibility studies were commissioned to evaluate 200 tons per
day ("tpd") and 1,000 tpd production options by Kilborn and Dynatec Mining
Corporation, respectively.  The 200 tpd study indicated diluted mineable
reserves of 131,000 tons at a grade of 1.132 oz. Au/t for 149,000 contained
ounces.  The second, larger scale underground study at 1,000 tpd used an 0.08
oz. Au/t cutoff and identifies diluted mineable reserves as 1.9 million tons at
a grade of 0.262 oz. Au/t for 497,000 contained ounces.

EXPLORATION

An additional resource was drilled out approximately 1 mile west of the main
deposit.  The Crabgrass target contains a near surface geologic resource at a
0.02 oz. Au/t cutoff of 24,000 ounces contained in 600,000 tons grading 0.038
oz. Au/t.  Several drilled and undrilled areas within the Grassy Mountain claim
block have potential for additional resources.

PROJECT STATUS

Based on pre-feasibility studies completed for underground development, the
Company believes that Grassy Mountain has the potential to be a low cost
producer.  Atlas plans to evaluate permitting and development of Grassy Mountain
with a joint venture partner.

GOLD BAR MINE
- -------------

LOCATION

The Gold Bar Resource Area is located in and adjacent to the Roberts Mountains
in Eureka County, Nevada, at elevations ranging from 6,400 to 8,800 feet above
sea level.  The area is reached by traveling 22 miles west of Eureka, Nevada, on
US Highway No. 50 and 17 miles northeast along the Three Bars Road.

PROPERTY

The Gold Bar Project area encompasses approximately 100 square miles.  There are
3,204 unpatented lode mining claims of which 3,025 are owned by Atlas and 179
are held through lease and option to purchase agreements.  Atlas also owns 182
unpatented millsite claims, 6 

                                      13
<PAGE>
 
patented lode claims and 8 patented millsite claims. Additionally, Atlas holds
under lease another 2,000 fee acres of surface with varying percentages of the
underlying minerals.

GEOLOGY

All of the mineralization found occurs as sediment-hosted, "Carlin-type"
deposits.  These deposits are hosted by carbonate-rich sedimentary rocks and are
characterized by micron size gold and a distinct hydrothermal alteration suite.
Gold mineralization and alteration are characteristically enriched in the trace
elements silver, antimony, arsenic, mercury, and thallium.

HISTORY

Regional reconnaissance exploration led the Company to the Battle Mountain Trend
area in the summer of 1983.  Focused reconnaissance along the southern Roberts
Mountains identified widespread hydrothermal alteration with anomalous gold
geochemistry along the western range front.  Detailed exploration in the area
subsequently led to acquisition of land, target development, and drilling.
Since then, the Company has discovered five gold deposits: Gold Bar, Goldstone,
Gold Ridge, Gold Pick, and Gold Canyon.  From inception through cessation of
operations in 1994, 485,200 ounces of gold were recovered from 7,514,600 tons of
ore grading .074 oz. Au/t milled.

Mill construction occurred during 1986 with the first gold poured in January,
1987.  The mill was originally designed and constructed for 1,500 throughput.
An expansion in 1989 increased throughput to the current 3,200 tpd rate.

RESERVES

Following suspension of mining operations at Gold Canyon, which occurred in
February of 1994, Atlas delayed plans for further mining of the Gold Pick and
Gold Ridge deposits pending additional drilling and further study of cost
cutting measures.  This confirmatory program included the drilling of 303
surface and 55 underground holes.

The mine plan for the Gold Pick and Gold Ridge deposits established proven and
probable mineable reserves which were independently audited by Mine Reserve
Associates of Denver, Colorado in December 1994.  Pincock, Allen & Holt, Inc. of
Denver, Colorado as part of its independent review of the Gold Bar Resource
Area, dated December 13, 1995, confirmed the following at a gold price of $400:

*    "Mineralized Material" is precious metal bearing rock that has been
physically delineated by one or more of a number of methods including drilling,
underground sampling and surface trenching and sampling.  This material has been
found to contain a sufficient amount of mineralization of an average grade of
metals to have economic potential that warrants further exploration and
evaluation.  Estimates of tonnage and grade are made on the continuity, size and
shape of the mineralization and have taken into account effects of waste mining
and dilution.
**   Advanced Prospects include Cabin Creek, Hunter, Gold Canyon and Pot Canyon.

JOINT VENTURES

As a result of the strategic decision to accelerate development of the entire
Gold Bar claim block, Atlas entered into joint venture arrangements with four
separate gold producing companies, Rayrock Yellowknife Resources, Inc.,
Homestake Mining Company, Hemlo Gold Mines (USA.), Inc. and Vista between July
of 1994 and September of 1995.  Active exploration programs conducted by these
companies on their respective areas of interest during 1994, 1995 and 1996 were
comprised of mapping, sampling and geophysical work as well as exploration
drilling.  Much information was gained concerning the exploration potential of
the Gold Bar Resource Area.  The four joint venture agreements were terminated
in 1996 and 1997.  As a result Atlas regained a 100% interest in the entirety of
the Gold Bar claim block, which contains the Company's Gold Bar mill.

In addition to existing reserves, Atlas has identified and partially defined
eleven high quality exploration targets, some with ore grade drill intercepts.
The Gold Pick and Gold Ridge deposits are unencumbered by royalties and are
controlled by unpatented mining claims for which first-half final certificates
have been issued by the Bureau of Land Management.  These are believed to
exempt the claims from federal royalties on production.  Atlas currently holds
the 

                                      15
<PAGE>
 
requisite environmental permits, licenses and waivers required by state and
federal authorities to operate the Gold Bar mine and mill.  There are no
requirements associated with the current permits that would prohibit the
restarting of mining operations.

Currently, the Company has decided not to pursue alternatives for self 
development of the property. However, various scenarios are being considered for
continued development including a joint venture for outright sale.

DOBY GEORGE PROPERTY
- --------------------

On October 25, 1995 Atlas purchased the Doby George property from Independence
Mining Company, Inc. ("Independence") for $400,000 in cash plus 1.4 million
common shares of Atlas.

LOCATION

Doby George is situated in northern Elko County, Nevada, approximately 60 air
miles north of the community of Elko.  The property is accessed by traveling
north of Elko on US Highway 225 for approximately 70 miles, then southwest on
Maggie Creek Summit Road another 12 miles.

PROPERTY

The Doby Project area encompasses approximately nine square miles in Elko
County, Nevada. Atlas owns 601 acres of fee land plus 240 unpatented lode mining
claims.  An additional 104 lode claims are held under three separate lease
agreements.

GEOLOGY

Rock types at Doby George are dominated by Mississipian Schoonover Formation
siliceous and limy siltstones, sandstones, cherts and quartzites, which host all
significant mineralization on the property.  Mineralization is generally
controlled by structure and stratigraphy.  High angle structures appear to be
related to the more significant mineralization with mineralization increasing in
both grade and thickness toward major structures.  Gold is fine grained and
commonly occurs within quartz veins and silicified zones.

                                      16
<PAGE>
 
HISTORY

The property was first identified by Felmont Oil Company, an affiliate of
Homestake Mining Company, in 1983.  Homestake conducted exploration drilling on
the property through 1991 when the property was sold to Independence.  A total
of 727 holes have been drilled at Doby on five separate deposits, and
metallurgical testwork has confirmed that the mineralization is generally not
refractory and is amenable to heap leach processing.  The drilling and mapping
to date have confirmed that a significant portion of the mineralization is
shallow, varying in thickness from 15 feet to 225 feet, and may be mined by open
pit methods.  The identified mineralized zones have been estimated by Behre
Dolbear & Company of Denver, Colorado, in an independent evaluation concluded in
July 1994, to contain 3.6 million tons of mineralized material at a grade of
0.06 oz. Au/t.

PROJECT STATUS

Atlas completed a $600,000 work program of additional drilling, metallurgical,
engineering and environmental studies on the previously identified West Ridge
and Red Tail deposits in order to confirm reserves.  The Company is currently
evaluating either joint venture exploration and development or a sale of the
property.

MUSGROVE CREEK PROPERTY
- -----------------------

The Musgrove Creek property is located in Lemhi County, Idaho, 25 miles
southwest of the town of Salmon. In November 22, 1996 the Company signed an
option with Meridian Gold Company ("Meridian") for the purchase of the Musgrove
Creek property and on February 28, 1997 Meridian exercised its option.  The
closing occurred on March 21, 1997.  For the property, Atlas received total
remuneration of $125,000 plus $27,000 as reimbursement of land holding costs.
Additionally, Meridian has agreed to assume a reclamation obligation of $55,000,
to convey to Atlas a 1% NSR on claims owned by Atlas and in the event Meridian
places minerals at Musgrove Creek into production, Atlas will receive an
additional $100,000.

INVESTMENTS
- -----------

VISTA GOLD CORP.
- ----------------

On August 15, 1994, the Company completed the purchase of 12,694,200 common
shares of Vista which represented 37.2% of the issued and outstanding shares of
Vista.  The purchase price was C$4.00 per share (US $2.80), or an aggregate
purchase price of C$50.8 million (US $35.8 million).  Vista is a Canadian-based
precious metals mining company with shares  traded on The Toronto Stock Exchange
and the American Stock Exchange.  Effective May 1, 1995, Vista amalgamated with
its subsidiary, Hycroft Resources and Development Corporation, reducing Atlas's
interest in the amalgamated entity to 27.5%.   On May 25, 1995, the Company
purchased 20,700 common shares of Vista which increased the Company's interest
to a total of 12,714,900.

On October 16, 1996 the Company sold 4,240,324 common shares of Vista for $1.32
per share. The Company continues to hold 8,474,576 Vista common shares, which
have been 

                                      17
<PAGE>
 
pledged as security for the Company's $9.81 million Exchangeable Debentures due
October 25, 2000. On October 22, 1996 an amalgamation between Granges Inc. and
Da Capo Resources Ltd. was approved by their respective shareholders to form
Vista, further reducing the Company's interest in the combined company to 9.6%

Operations at Vista's Hycroft mine, located near Winnemucca, Nevada have
consistently produced between 80,000 to 100,000 ounces of gold annually since
1989.  Given its identified reserves and current level of production, Vista has
stated that production is scheduled to continue through the year 2001.

The Company reported the results of Vista's operations using the equity method,
from August 15, 1994, when its share position in Vista's predecessor was
acquired, until the fourth quarter of 1996, during which quarter the Company's
equity was reduced to 9.6% as a consequence of the sale of the shares. As a
result, beginning with the 4th quarter and in accordance with Generally Accepted
Accounting Principles, the Company changed its method of accounting whereby it
records marketable securities at fair market value.  For the fiscal periods
ended December 31, 1996 and 1995 and June 30, 1995, Atlas recorded equity losses
of $2.72 million, $1.7 million and $1.36 million, respectively, attributable to
the operations of Vista.  These amounts include Atlas's proportional share of
Vista operating results, and an additional charge of approximately $34 per ounce
of Vista production as an amortization of Atlas's excess carrying cost above
Vista book value.

DISCONTINUED OPERATIONS
- -----------------------

Uranium Mill Site, Moab, Utah
- -----------------------------

Atlas's Moab mill site (the "Site") is located in Grand County, Utah.  The Site
is located on the northwest shore of the Colorado River, 3 miles northwest of
the center of Moab and can be accessed from US Highway 191 north of Moab.  The
Site encompasses 437 acres on the outside bend of the Colorado River, at the
southern terminus of the Moab Canyon, approximately 4,000 feet above mean sea
level.

Of the 437 acres owned by Atlas, the plant site and tailings pond combined cover
approximately 200 acres.  Before decommissioning, the plant site was composed of
a main processing plant, a 130-acre tailings pond, storage yards, ore receiving
facilities, various process-related structures, and an office complex.

The Uranium Reduction Company ("URC") built and began operations at the Moab
Mill (the "Mill") in October 1956.  Atlas acquired URC in 1962 and operated the
Mill until 1984 when it was placed on stand-by status.  Atlas holds US Nuclear
Regulatory Commission ("NRC") Source Material License SUA-917 for the Mill,
which was changed to a possession only status on December 18, 1992.

The Mill was authorized to extract uranium oxide by both the acid and alkaline
leach processes and was licensed for production at 850 metric tons (1,870,000
pounds) of yellowcake annually.  During the life of the Mill, only one tailings
pond was used.

                                      18
<PAGE>
 
The majority of the ore for the Mill came from the Big Indian Uranium District
approximately 80 miles to the southeast.  The ore was primarily a sandstone with
minor amounts of carbonate.  Ore was trucked to the Mill and ground to a
sufficiently fine consistency to allow maximum efficient chemical reactions to
occur.  It was then processed through either the acid-leach circuit or the
alkaline-leach circuit, both of which were used in the Mill.  After milling, the
combined waste slurry from both circuits was pumped to the tailings impoundment.

The approximate wet weight of the tailings contained within the tailings pile
was determined to be 10.5 million tons, with a volume of 7.5 million cubic
yards.  The tailings pile is composed of fine tailings (slimes), coarse tailings
(sand), and ore which was placed there at the end of the operation of the Mill
as part of an interim cover.

A decommissioning plan for the Mill was approved on November 28, 1988.
Decommissioning of the Mill began in 1988, and interim cover placement over the
tailings disposal area began in 1989 and was completed in 1995.

A reclamation plan for the tailings pile was prepared by Atlas in 1981 and
approved by the NRC in 1982.  The plan was based on the projected life of
facility tailings capacity requirements; the disposal pile was designed for an
ultimate crest elevation of 4,076 feet.  The maximum crest elevation constructed
before the Mill ceased operation was 4,058 feet, resulting in the necessity to
revise the reclamation plan.  Atlas, by letter dated August 2, 1988, submitted a
revised reclamation plan for NRC review and approval.  In 1990, the NRC changed
its technical criteria which resulted in requests for additional information,
reevaluation, and redesign.  As a result, Atlas submitted a revised reclamation
plan in 1992.  On July 20, 1993, NRC gave notice in the Federal Register of its
intent to approve the reclamation plan and made available for public comment an
environmental assessment of the effects of the proposed action, which addressed
only the environmental effects of changes to the plan approved in 1982.  The
comments received prompted NRC to withdraw, by Federal Register notice dated
October 8, 1993, its previously noticed intent to approve the revised
reclamation plan.  On March 30, 1994, NRC announced its intent to prepare an
Environmental Impact Statement ("EIS") to evaluate potential impact to the
environment of the proposed plan and certain alternative proposals.

Atlas's proposed reclamation plan (the "Plan") would allow the Company to (1)
reclaim the tailings pile for permanent disposal and long-term custodial care by
a government agency in its current location on the Site, (2) prepare the Site
for closure, and (3) relinquish responsibility of the Site after having its NRC
license terminated.  Closing the pile consists of recontouring the tailings pile
to allow for the natural drainage of precipitation and covering with earthen
material and rock to control radon emanations and prevent erosion.

                                      19
<PAGE>
 
The Company has nearly completed the regulatory process for approval of the
Plan.  On March 7, 1997 the NRC issued its Technical Evaluation Report ("TER")
which acknowledges that the Plan is in compliance with the technical
requirements for capping the tailings facility onsite.  The TER is used to
evaluate compliance with regulatory and safety criteria.  While NRC's issuance
of the TER is a favorable development, the regulatory approval process is not
complete until the NRC issues the final EIS which is anticipated in mid to late
1997.  In the draft EIS issued in January, 1996 the NRC staff concluded that
Atlas's proposal to reclaim the pile in place is acceptable and less costly than
the alternative.  The TER concludes that the proposed reclamation plan satisfies
the regulatory requirements.  Construction is planned to commence in early 1998.
For further information on the Moab site reclamation, see "Management's
Discussion and Analysis of Financial Position and Operating Results -
Environmental Matters".

When reclaimed, approximately 250 acres, which encompass the capped tailings and
reconfigured Moab Wash, will be deeded to the federal or state government.  The
remaining acreage, approximately 187 acres, would be released to Atlas for
unrestricted use.  A substantial portion of the remaining land would be
available for commercial use with an estimated value at current market prices in
excess of $1.5 million.

Asbestos Mine Site, Coalinga, California
- ----------------------------------------

Remedial construction activities at the Company's former asbestos mine and mill
site located near Coalinga, California, which began in October 1994, are
complete.  Atlas, which operated the mine for a five year period in the 1960s
was notified by the Environmental Protection Agency in fiscal 1988 that the
Bureau of Land Management, and several other subsequent owners were potentially
responsible parties under the Comprehensive Environmental Response, Compensation
and Liability Act for cleanup costs at the mine site.  The Environmental
Protection Agency issued its "Approval of Construction Completion" November 14,
1996 two years after the remedial action plan was approved.  For further
information on the Coalinga reclamation, see "Management's Discussion and
Analysis of Financial Position and Operating Results - Environmental Matters".

RISK FACTORS
- ------------

The Company's profitability has been significantly affected by metal prices.
These prices may fluctuate widely and are affected by numerous factors beyond
the Company's control, including global and regional demand, production costs,
transportation and smelting charges, political and economic conditions, strength
of the United States dollar and exchange rates.

Gold, lead, zinc and silver are products which can be easily sold on numerous
markets throughout the world.  It is not difficult to ascertain the market price
for these metals at any particular time, and these metals can be sold to a large
number of refiners or metals dealers on a competitive basis. The Company
normally sells its metals production through major dealers, in some cases may
use hedging programs, and is free to sell uncommitted metals to others.

Sales of finished perlite are individually negotiated with end users.  There are
no guarantees that the Company will be able to obtain sales commitments in
quantities or at prices sufficient to make a profit.

                                      20
<PAGE>
 
The Company is required to comply with various federal, state and local
regulations and requirements relating to environmental matters at its mining
properties.  The Company is required to obtain permits from various governmental
agencies in order to mine and mill.  The Company has obtained all of the
necessary permits relating to its on-going operations. The Company cannot
anticipate whether increasing costs of environmental compliance for its mining
operations will have a material adverse impact on planned operations or
competitive position.

The Company competes with substantially larger companies in the production and
sale of industrial minerals.  The Company does not believe that it or any other
competitor is a material factor in these markets, and the price it receives for
its production depends almost entirely upon market conditions over which it has
no control.  The Company believes that it can promptly sell at current market
prices all of the metals that it can produce.

With respect to the acquisition of mineral interests and exploration activities,
the Company competes with numerous persons and companies, many of which are
substantially larger and have considerably greater resources than the Company.

Item 2. PROPERTIES
        ----------

The Company's materially important properties consist of the Andacaba, Don
Francisco and Koyamayu mines which produce lead, zinc and silver in Bolivia,
Tucker Hill which produces perlite, Gold Bar which contains gold resources, and
to the Doby George and Grassy Mountain gold properties, described under "Item 1

Item 7.    Condition and Results of Operations
           -----------------------------------

The following discussion and analysis should be read in conjunction with the
Company's Consolidated Financial Statements and accompanying notes.

During 1995, the Board of Directors authorized a change in Atlas's fiscal year-
end to December 31.  This change was implemented during 1995, and resulted in
financial information being reported for the  six month period ended December
31, 1995.

WORKING CAPITAL, LIQUIDITY AND CAPITAL RESOURCES
- ------------------------------------------------

Between the summer of 1994 (briefly before the suspension of milling operations
at the Company's Gold Bar mine in September 1994) and early 1996, the Company
completed several financings, the proceeds of which were used to complete
acquisitions and to raise working capital.  During the summer of 1994, the
Company raised $50 million through private placement of 9,090,909 Units for a
purchase price of $5.50 per Unit, each Unit consisting of one share of Atlas
Common Stock and one-half of one warrant (exercisable for five years) to
purchase one share of Atlas Common Stock at an exercise price of $7.00 per
share. The financing closed in escrow in August 1994. Of $50 million raised,
$35.5 million was released from escrow on August 15, 1994, allowing Atlas to
complete the acquisition of 12,694,200 common shares (37.2% of the outstanding
shares) of Vista (see Item 1. "Investments - Vista Gold Corp."). The remaining
$14.5 million was released on December 15, 1994, following shareholder approval
of a proposal to increase the number of Atlas Common Shares authorized for
issuance. Of this amount, $3.2 million was ultimately used in March 1995 to
acquire 2.4 million shares (or 9% of the outstanding shares) of Dakota Mining
Corporation ("Dakota"). In November 1995, the Company completed a private
placement of $10 million 7% Exchangeable Debentures ("Debentures") due October
25, 2000. The debentures were secured by the pledge of 8,474,576 of the Vista
shares. The debentures are exchangeable at the option of the holder into shares
of Vista at the rate of 42.5 shares per $100 of debentures held. See Item 8.
"Financial Statements and Supplementary Data."

In March 1996, the Company sold its 2,419,000 common shares of Dakota for $4.5
million and in October 1996, it sold the 4,240,324 shares of Vista not pledged
for net proceeds of $5.5 million.

The above transactions, in addition to financing the acquisitions noted above,
have allowed the Company to acquire its interest in Arisur (see Item 1. "ARISUR
INC.") and to develop its Tucker Hill perlite project (see Item 1. "TUCKER
HILL").  These expenditures, combined with a lack of operating revenues during
this time period, have resulted in large swings in the Company's working capital
position.

Working capital decreased by $12.2 million during 1996.  This was a result of
acquisition costs of Arisur of approximately $3.7 million, construction and
development costs at Tucker Hill and Andacaba of $4.1 million, ongoing
exploration, standby and administrative costs totaling $7.1 million and net
uranium reclamation costs of $1.8 million, partially offset by the sale of 
Vista shares noted above.

During the year ended December 31, 1995, working capital increased by $1.4
million to $9.7 million at December 31, 1995. The increase reflects the $10
million proceeds from the issuance 

                                       24
<PAGE>
 
of Exchangeable Debentures, less $2.4 million net asbestos and uranium
reclamation costs, $1.7 million in project development expenditures, and $4.4
million in general and administrative costs and other working capital changes.

Working capital was $5.6 million at June 30, 1995, which compares to a working
capital deficit of $200,000 at June 30, 1994. The positive change in working
capital reflects the funds received from the issuance of units of common stock
warrants described above, which were partially applied to the purchase of Vista
shares. The remaining proceeds were in part used to repay a short term loan, to
pay fees related to the private placement of the units, to acquire 2.4 million
shares of Dakota Mining Corporation for $3 million and for continuing
exploration and administration expenses.

During 1997, the Company will focus its efforts on the continuing development of
its Bolivian operations, both through expansion of its current mine and mill
operations as well as through the identification and acquisition of other
promising properties in the area.  In addition, Cornerstone will complete
construction at Tucker Hill, which will transition from the development stage to
commercial during 1997.  The Company will also evaluate development options for
Grassy Mountain that, in the near term, will be dependent upon the Company's
ability to obtain sufficient financing.

In February 1997, Arisur signed a financing agreement with the Corporacion
Andina de Fomento ("CAF") for US$3 million dollars.  CAF is a multilateral
financial institution that supports sustainable development and integration
efforts within the Andean region of South America.  The proceeds of the loan
will pay for certain equipment and expansion programs of the Bolivian operations
and will reimburse Atlas in excess of $500,000 of funds previously advanced for
said purposes.  The proceeds of the loan are expected to be released when
certain guarantees and property liens have been completed.  

Pending the commencement of significant cash flows from Cornerstone and the 
Company's Bolivian properties, the Company is actively considering a number of 
sources for short-term working capital. In particular, the Company is actively 
evaluating several possible transactions involving the joint venture, option or 
sale of its gold properties at Gold Bar, Doby George and Grassy Mountain. The 
Company also continues aggressively to pursue other sources of funding, 
including potential mergers with companies holding sufficient cash reserves.

The Company is also evaluating the leveraging of its unencumbered properties and
of its restricted cash and Title X receivable (See Item 7. "ENVIRONMENTAL 
MATTERS") in order to secure short or long-term funding as appropriate.
Management believes that the above actions, along with the continued cooperation
of the Company's creditors and stringent management of cash resources, will
enable the Company to meet its short term cash requirements. 

                                       25
<PAGE>
 
The Company believes that its mining operations will generate positive
cash flows beginning in 1998, and will allow the Company to be less dependent on
the debt and equity markets for its working capital needs in the future.

In order to meet its estimated long term reclamation obligations the Company
will utilize its restricted cash and securities, which supports the bonding of
such obligations, and reimbursements due under the Title X reimbursement
program.  See Item 7. "ENVIRONMENTAL MATTERS."

During the year ended December 31, 1996, the Company's capital expenditures were
$4.4 million, compared with $1.7 for the comparable 12 month period in 1995.  In
1996, development and construction costs incurred at Tucker Hill were
approximately $3 million, mine and mill expansion costs at Andacaba were $1.1
million, and acquisition costs of Grassy Mountain were $.2 million.  For the
year ended December 31, 1995, $500,000 was spent on the development of Tucker
Hill, and a total of $1 million was incurred on the Commonwealth and Doby George
properties.  The remainder of expenditures were primarily related to the Gold
Bar property.

The Company's capital expenditures in the six months ended December 31, 1995
were $1.4 million, compared to $.3 million for the comparable period in 1994.
During the six months ended December 31, 1995, development costs of $365,000,
$353,000 and $643,000 were incurred on the Tucker Hill, Commonwealth, and Doby
George properties, respectively. Substantially all of the capital expenditures
incurred during the six month period ended December 31, 1994 related to Tucker
Hill development costs.

The Company's capital expenditures incurred during the fiscal year ended June
30, 1995 were $.6 million, compared to $5.2 million during the fiscal year ended
June 30, 1994.  In fiscal 1995, the majority of the funds were spent on the
development of Tucker Hill with the remainder being spent on the Gold Bar
property.  In fiscal 1994, substantially all of the capital expenditures were
for the development of the Gold Bar property.

RESULTS OF OPERATIONS
- ---------------------

Year Ended December 31, 1996 Compared to the Year Ended December 31, 1995:
- ------------------------------------------------------------------------- 

Revenues

As a result of the acquisition of Arisur in October, the Company had mining
revenues of $578,000 in 1996 relating to sales of lead, zinc and silver
concentrates from the Andacaba mine.  This compares with no mining revenues for
the year ended December 31, 1995 due to the suspension of milling operations at
Gold Bar in 1994.

                                       26
<PAGE>
 
Operating/Production Costs

Operating costs in 1996 reflect production costs of $441,000 and depreciation,
depletion and amortization costs of $324,000 incurred in Bolivia as a result of
the Arisur acquisition and shutdown and standby costs of $1,232,000.  During the
same period in 1995, the Company incurred shutdown and standby costs of
$882,000.  The standby and shutdown costs were lower in 1995 due to a $1,275,000
accrual for future costs at September 30, 1994, resulting in a reduction of
costs charged in 1995.

Exploration

The Company had exploration costs of $1,264,000 for the year ended December 31,
1996 as compared to $1,113,000 for the year ended December 31, 1995.  Costs
incurred in 1996 primarily reflect work performed on the Commonwealth property
whereas 1995 costs reflect exploration and holding costs on the Gold Bar claim
block.

General and Administrative

General and administrative expenses incurred in 1996 were $4,658,000, an
increase of $1,490,000 from 1995 costs of $3,168,000.  This increase is largely
attributable to the addition of Cornerstone general and administrative costs of
$547,000, severance costs of $830,000 related to the resignations of David J.
Birkenshaw as Chairman and CEO of the Company and Gerald E. Davis as President
of the Company, and approximately $300,000 reflecting costs associated with
unsuccessful merger discussions with MSV Resources Inc.

Other

In March 1996, the Company sold its interest in Dakota Mining Corporation for
approximately $4.5 million, resulting in a gain of $1.3 million.  In October
1996, the Company sold 4.2 million shares of Vista for total proceeds of $5.6
million that resulted in a loss of $1.5 million.

Six Months Ended December 31, 1995 Compared to Six Months Ended December 31,
- ----------------------------------------------------------------------------
1994:
- ----

Revenues

Due to the suspension of milling operations at the Gold Bar Project in September
1994, the Company had no mining revenues for the six months ended December 31,
1995.  This compares to mining revenue of $2,328,000 and gold production of
6,021 ounces generated from Gold Bar during the six months ended December 31,
1994.

Operating/Production Costs

The Company had no operating costs in the six months ended December 31, 1995.
Operating costs for the six month period ended December 31, 1994, which was
marked by the suspension of milling activities at Gold Bar on September 19,
1994, included production costs of $2,683,000, depreciation, depletion and
amortization of $348,000 and the accrual of shutdown and standby costs of
$1,275,000.  Production costs at the Gold Bar property increased to $446 per
ounce, or 

                                       27
<PAGE>
 
115% of revenue, due to the processing of low grade ore from depleting
stockpiles. The $1,275,000 accrual for shutdown and standby costs recorded in
September 1994 reflected the projected shutdown and standby costs to be incurred
through the remainder of fiscal 1995.

Exploration

The Company incurred exploration costs of $307,000 during the six months ended
December 31, 1995 for continued exploration efforts on the Gold Bar property, as
compared to $1,105,000 for the six months ended December 31, 1994.  This
decrease reflects the cost savings associated with entering into the joint
venture agreements covering approximately 80% of the Gold Bar claim block as
compared to the underground exploration conducted at Gold Bar during the six
months ended December 31, 1994.

General and Administrative

General and administrative expenses for the six months ended December 31, 1995
were $1,798,000 compared to $1,372,000 for the six months ended December 31,
1994.  This increase was primarily a result of an intensified property
acquisition program and relocation expenses.

Year Ended June 30, 1995 Compared to Year Ended June 30, 1994:
- -------------------------------------------------------------

In January 1994, production from the Gold Bar property was halted after a
confirmatory drill program indicated that mining to the originally designed Gold
Canyon pit bottom would have been uneconomical due to the occurrence of more
refractory material than had been previously forecast. Management initiated the
processing of low grade stockpiled ores in an effort to avoid the suspension of
milling operations.  Engineering and metallurgical studies focusing on the
development of short-term reserves were accelerated.  On September 16, 1994,
stockpiled ores were depleted and the Company was forced to suspend milling
operations and to temporarily place the Gold Bar property on standby.  As a
result, the fiscal year ended June 30, 1995 reflects only three months of
operations.

Revenues

Revenues for the years ended June 30, 1995 and 1994 were $2,328,000 and
$19,478,000, respectively.  Gold production decreased to 6,021 ounces in fiscal
1995 from 51,700 ounces in fiscal 1994.  The decreases in revenue and gold
production in fiscal 1995 reflect the suspension of operations at the Gold Bar
property after only three months of production.  The average price per ounce of
gold realized in fiscal 1995 was $387 versus $377 in fiscal 1994.

Operating/Production Costs

Production costs for fiscal 1995 and 1994 were $2,683,000 and $16,526,000,
respectively. Production costs per ounce in fiscal 1995 and 1994 were $446 and
$319, respectively.  The decreases in production costs are a result of the
suspension of operations at the Gold Bar property after three months of
production in fiscal 1995.  The higher production costs per ounce reflect the
lower grades of ore run subsequent to the suspension of mining operations.

The Company incurred $1,485,000 in shutdown and standby costs during the last
three quarters of fiscal 1995.  Such costs included severance payments,
continuing onsite security and maintenance as well as general and administrative
expenditures.

During the fourth quarter of fiscal 1994, the Company and an independent
consultant began evaluating the Gold Bar mine plan and remaining known ore
reserves.  As a result, the Company determined that its remaining unamortized
costs could not be recovered from undiscounted cash flows over the remaining
mine life and the Company recognized an impairment to adjust the carrying value
of its assets with the property being written down to estimated salvage value.
This adjustment resulted in a charge to operations of $5,355,000 in the fourth
quarter of fiscal 1994.

Depreciation, depletion and amortization charges of $348,000 in fiscal 1995
represent the flow through of non-cash costs contained in stockpiled ore
inventory at the end of fiscal 1994 and the write-off of capital expenditures
incurred during the three months of operations in fiscal 1995.

Exploration Costs

Exploration costs of $1,911,000 were incurred in fiscal 1995, a decrease of
approximately $400,000 from fiscal 1994.  The decrease is attributable to the
reduction of land holding costs, as joint venture partners (see below) were
responsible for land royalties and lease payments, and to a reduction of
personnel.  Exploration costs in fiscal 1994 increased $430,000 from fiscal 1993
as a result of an underground drilling program commenced in the fourth quarter
of fiscal 1994 and ended during the first quarter of fiscal 1995.

General and Administrative

General and administrative expenses decreased by $326,000 from $3,068,000 in
fiscal 1994 to $2,742,000 in fiscal 1995, or 11%.  The primary reason for the
decrease was a $400,000 reduction in salaries and severance costs.

Other

During the first quarter of the fiscal year ended June 30, 1995, the Company
acquired a 37.2% interest in Vista, and recorded an equity loss of $1,361,000
during the remainder of the year.  Following the merger of Vista with its 50.5%
subsidiary, Hycroft Resources and Development Corporation, Atlas re-evaluated
its investment in Vista relative to the fair values implied in the amalgamation
and to the known reserves at the Crofoot/Lewis mine.  As a result, the Company
recorded an $11,419,000 impairment of its investment in Vista as of June 30,
1995.

During October 1994, Atlas recorded a $1,144,000 loss related to the forfeiture
of a non-refundable deposit on the purchase of securities in Dakota.  Atlas's
decision to forfeit the deposit was based on its review of the relative market
and purchase prices.  In March 1995, Atlas entered into an agreement to purchase
approximately 2.4 million common shares of Dakota for $3,000,000, whereby each
company released the other from any liability arising out of the previous
agreement.

Notes 13 and 14 to the Financial Statements provide details and a discussion of
discontinued operations for the past three fiscal years.

ENVIRONMENTAL MATTERS
- ---------------------

The Company is subject to extensive federal, state and local environmental laws
and regulations.  These laws, which are constantly changing, regulate the
discharge of materials into the environment and may require the Company to
mitigate any environmental effects caused by its operations.  The Company
believes that it is currently in substantial compliance with all federal, state
and local environmental regulations applicable to its current and discontinued
operations.

The Company is obligated to decommission and reclaim its uranium mill site
located near Moab, Utah.  When the Company discontinued its uranium operations
in 1987, estimated shut-down and reclamation expenses of $17,406,000 were
accrued.  Reclamation and decommissioning costs (net of reimbursements, see
below) of $1,808,000, $1,189,000, $1,497,000 and $1,159,000 have been charged
against this accrual for the year ended December 31, 1996, six months ended
December 31, 1995, and the fiscal years ended June 30, 1995 and 1994.  The
balance of this accrual at December 31, 1996 was $2,705,000 and the reclamation
plan as proposed by the Company extends over the next three to six years.  Title
X of "The Comprehensive National Energy Policy Act" ("Title X"), which was
enacted in October 1992, provides for reimbursement by the federal government of
past and future reclamation expenses in proportion to the extent that the site's
tailings were generated by Atomic Energy Commission (AEC) contracts.  With
respect to the Company's discontinued uranium operations, 56% of the tailings
were generated by AEC contracts.  Requests for reimbursement under Title X must
be submitted annually to the Department of Energy ("DOE") and are subject to
review and audit. The timing on the repayment of costs approved for
reimbursement is a function of Congressional appropriation.

In July 1994, the Company submitted the first of three claims under Title X of
the 1992 Energy Act for reimbursement of compliance and reclamation costs.  The
claims cover costs incurred from fiscal 1980 through March 1996.  The amount
reimbursable under the three claims is $6,817,000.  As of March 30, 1997, the
Company had received $3,345,000 in reimbursements under Title X.  The $3,472,000
not yet reimbursed has been charged against the Company's reclamation accrual.
In addition to this amount, $500,000 has not yet been approved pending further
review.

On January 30, 1996, the Nuclear Regulatory Commission ("NRC") released a draft
Environmental Impact Statement ("EIS") and a draft Technical Evaluation Report
("TER") regarding the Company's reclamation proposal.  Atlas's proposed
reclamation plan consists of contouring the tailings pile to allow for the
natural drainage of precipitation and the addition of an earth and rock cover to
prevent erosion and minimize radon emanation.  The current EIS process is being
used by the NRC to evaluate the environmental impact of the Company's proposed
plan and an alternative proposal. In the draft EIS, the NRC staff preliminarily
concluded that Atlas's proposal to reclaim the pile in place was acceptable and
less costly than the proposed alternative.  The final TER, dated March 7, 1997,
concluded that the Atlas reclamation plan was in compliance with the technical
requirements for capping the tailings facility on-site.

                                       30

The Company is confident that the ultimate result of the EIS review process, in
conjunction with the supportive conclusion of the TER will be the approval of
its reclamation plan, and that its remaining accrual, when combined with
anticipated reimbursements of reclamation costs under the Title X program and
restricted cash used for surety collateral, is sufficient to cover future
reclamation costs.

Estimated reclamation costs relating to the Gold Bar Resource Area are recorded
based on the units of production method.  Total reclamation costs expensed in
the twelve month periods ended December 31, 1996, the six month period ended
December 31, 1995 and the fiscal years ended June 30, 1995 and 1994 were $0, $0,
$0 and $732,000, respectively.  As part of the impairment recorded during the
fourth quarter of fiscal year 1994 (see results of operations, above), the
Company increased its accrued expense by an additional $1,244,000. No charges
were recorded in 1996 since analysis indicated the $3,118,000 accrued for
reclamation costs at the Gold Bar Resource Area is adequate.

The Company believes it can meet the estimated closing and reclamation costs of
its uranium and gold mining operations from internally generated funds, from the
$6,266,000 in restricted cash which serves as collateral for letters of credit
and reclamation bonds relating to these costs, and from reimbursements under
Title X, without a significant impact on its working capital position.  It is
presently anticipated that these obligations will be satisfied over the next
three to six years.

During fiscal 1988, the United States Environmental Protection Agency notified
the Company that it was one of several potentially responsible parties ("PRPs")
under the Comprehensive Environmental Response, Compensation and Liability Act
("CERCLA") for cleanup costs at the Company's former asbestos mine and mill site
near Coalinga, California and in the City of Coalinga.  In fiscal 1993 and 1991,
the Company established a reserve of, and recorded as an expense, $600,000 and
$3,000,000, respectively, to cover the Company's share of costs to be incurred
in connection with this matter.  This accrual reflects participation by the BLM,
which was also named as a PRP.  The Company instituted legal action against 13
insurance carriers which had issued insurance policies over a period of more
than 25 years with respect to these sites. During fiscal 1994, the Company
reached settlement with a number of these carriers and recorded a gain from
discontinued operations of $2,175,000.

In October 1994, the Environmental Protection Agency approved a remedial action
plan for the sites.  Due to unusually heavy rains experienced at the site during
the spring and early summer of 1995, the Company experienced delays and cost
overruns.  As a result, the Company recorded an additional loss from
discontinued operations of $225,000 in the fourth quarter of fiscal 1995.  The
Environmental Protection Agency issued its "Approval of Construction Completion"
on November 14, 1996.

The Company is required to obtain permits from various governmental agencies in
order to mine and mill ores.  The Company has obtained all of the necessary
permits relating to its planned operations.  The Company cannot anticipate
whether the increasing costs of environmental compliance for its operations will
have a material adverse impact on its future operations or competitive position.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                   ------------------------------------------

1. ACCOUNTING POLICIES

Basis of Presentation --  The accompanying financial statements have been
prepared assuming that the Company will continue as a going concern.  The
Company has incurred operating losses of $10,358,000, $4,266,000, $20,397,000
and $12,040,000 for the year ended December 31, 1996, the six months ended
December 31, 1995 and the fiscal years ended June 30, 1995 and 1994,
respectively and has a working capital deficit of $2,528,000 at December 31,
1996.  These considerations raise substantial doubt about the Company's ability
to continue as a going concern.  The financial statements do not include any
adjustments to reflect the possible future effects on the recoverability and
classification of assets or the amounts and classification of liabilities that
may result from the outcome of this uncertainty.  

Management's plans to alleviate the substantial doubt include the following:

In February 1997, Arisur signed a financing agreement with the Corporacion
Andina de Fomento ("CAF") for US$3 million dollars.  CAF is a multilateral
financial institution that supports sustainable development and integration
efforts within the Andean region of South America.  The proceeds of the loan
will pay for certain equipment and expansion programs of the Bolivian operations
and will reimburse Atlas in excess of $500,000 of funds previously advanced for
said purposes.  The proceeds of the loan are expected to be released when 
certain guarantees and property liens have been completed.

Pending the commencement of significant cash flows from Cornerstone and the 
Company's Bolivian properties, the Company is actively considering a number of 
sources for short-term working capital. In particular, the Company is actively 
evaluating several possible transactions involving the joint venture, option or 
sale of its gold properties at Gold Bar, Doby George and Grassy Mountain. The 
Company also continues aggressively to pursue other sources of funding, 
including potential mergers with companies holding sufficient cash reserves.

The Company is also evaluating the leveraging of its unencumbered properties and
of its restricted cash and Title X receivable (note 14) in order to secure short
or long-term funding as appropriate. Management believes that the above actions,
along with the continued cooperation of the Company's creditors and stringent 
management of cash resources, will enable the Company to meet its short term 
cash requirements.

Principles of Consolidation --  The accompanying consolidated financial
statements include the accounts of the Company and all majority-owned
subsidiaries.  All significant intercompany balances and transactions have been
eliminated.  Minority interest represents the share of Cornerstone Industrial
Minerals Corporation not owned by the Company.

                                       37
<PAGE>
 
Change in Fiscal Year --  The Company changed its fiscal year from June 30 to
December 31 effective December 31, 1995.

Inventories --  Inventories other than finished gold are recorded at the lower
of average cost or net realizable value.   Finished gold inventory is carried at
realizable value.

Mining Costs --  During production periods, costs attributable to waste are
charged to operations based on the average ratio of waste tonnage to ore
tonnage.

Property, Plant and Equipment --  Property, plant and equipment is stated at the
lower of cost, or estimated net realizable value.  Depreciation of milling
facilities and depletion of mining properties is determined by the units of
production method.  The Company regularly assesses its ability to recover the
carrying value of its assets and recognizes an impairment when it is determined
that unamortized costs cannot be recovered from undiscounted cash flows over the
remaining project life.  Leasehold improvements are amortized on a straight-line
basis over the terms of related leases or, if shorter, estimated useful life.

Expenditures for maintenance and repairs are charged to operations as incurred.
Expenditures for additions and major renewals are added to the property, plant
and equipment accounts.  Interest expense allocable to the acquisition or
construction of capital assets and deferred mine development is capitalized
until operations commence.

Investments --  The Company uses the equity method to account for investments in
common stock of companies 20% to 50% owned. Marketable equity securities
available for sale are recorded at fair value with unrealized gains and losses
reported as a separate component of stockholders' equity.

Effective June 30, 1995, the Company changed its method of recognizing the
equity in earnings of companies accounted for under the equity method from
reporting the results of operations on a three month lag period to reporting the
results of operations on a current basis.

Excess of Cost over Net Assets Acquired --  The excess cost of acquisition over
net assets acquired from Cornerstone Industrial Minerals Corporation is being
amortized on a straight-line basis over five years.  Amortization expense for
the year ended December 31, 1996 and the six month period ended December 31,
1995 was $90,000 and $7,000, respectively.

Foreign Currencies --  All assets and liabilities of foreign subsidiaries are
translated into U.S. dollars using the exchange rate prevailing at the balance
sheet date, while income and expense items are translated at the weighted
average exchange rate prevailing during the period. Unrealized exchange gains
and losses are deferred and shown as a currency translation adjustment in
shareholders' equity.

Exploration and Mine Development --  Exploration costs are expensed as incurred.
When it is determined that a property has development potential, the subsequent
costs of exploration and development are capitalized. Upon commencement of
production the capitalized costs are amortized using the units of production
method.

Mining Revenue --  Gold revenues are recorded when the finished product is
available for shipment. Revenues on base metals are recorded at the time of
shipment.

                                       38
<PAGE>
 
Reclamation --  Estimated reclamation, site restoration and closure costs for
each mine are charged to operations over the expected life of the mine using the
units of production method.

Income Taxes --  The Company accounts for income taxes under Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes" (SFAS
109).  SFAS 109 is an asset and liability approach that requires the recognition
of deferred tax assets and liabilities for the expected future tax consequences
of events that have been recognized in the Company's financial statements or tax
returns.  In estimating future tax consequences, SFAS 109 generally considers
all expected future events other than enactments of changes in the tax law or
rates.  Income tax accounting information is disclosed in Note 17 to the
consolidated financial statements.

Cash Equivalents --  The Company considers all highly liquid investments
purchased with a maturity of three months or less to be cash equivalents.

Earnings per Share --  Earnings per share have been calculated based on the
weighted average number of common shares outstanding during the year.  Shares
issuable under options and warrants are excluded from the computation when they
are not dilutive.

Long-Lived Assets --  In March 1995, the FASB issued Statement No. 121,
"Accounting for the Impairment of Long-Lived Assets and for Long-Lived Assets to
be disposed of", which requires impairment losses to be recorded on long-lived
assets used in operations when indicators of impairment are present.  The
Company adopted Statement No. 121 in the first quarter of 1996.  The effect of
adoption was not material.

Accounting Estimates in the Preparation of Financial Statements --  The
preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the reported amount 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.

Reclassifications --  Certain of the comparative figures have been reclassified
to conform with the current year's presentation.

4.  INVESTMENTS IN MARKETABLE EQUITY SECURITIES

On May 31, 1994, the Company, Dakota Mining Corporation ("Dakota") and
VenturesTrident, L.P. and VenturesTrident II, L.P. entered into an agreement in
principle providing for (i) the purchase of 1,500,000 common shares of Dakota
from the VenturesTrident Partnerships, for $4.00 per share, and, subject to the
completion of the purchase of the VenturesTrident Shares, (ii) the subscription
by Atlas to 3,100,000 newly-to-be issued convertible preferred shares of Dakota.
On October 28, 1994, the Company determined that, based upon the prevailing
market conditions, it was in the best interests of its shareholders not to
proceed with the Dakota acquisition and forfeited $1,000,000 in nonrefundable
deposits to the VenturesTrident Partnerships.  Costs of $144,000 incurred in
conjunction with the Dakota transaction were also expensed.

On March 9, 1995 Atlas and Dakota entered into a Subscription Agreement, under
which Atlas purchased 2,419,355 Special Warrants of Dakota at a price of $1.24
per Special Warrant which were subsequently converted into 2,419,355 Common
Shares of Dakota.  As a result of such purchase, the Company owned over 9% of
the outstanding Common Shares of Dakota.  In connection with the purchase by the
Company of Special Warrants, the Company and Dakota executed a mutual limited
release, whereby each party released the other from any liability arising out of
the May 31, 1994 agreement.

On March 9, 1996 the Company sold its 2,419,355 common shares of Dakota Mining
Corporation for U.S. $1.87 per share, or U.S. $4,519,000.  The Company
recognized a gain in 1996 on this sale of $1,332,000.

As further described in note 9, the Company's investment in Vista Gold Corp.
fell below 20% in the fourth quarter of 1996.  Accordingly, the investment is
treated as a marketable equity security at December 31, 1996.

</TABLE> 

Short-Term Assets and Liabilities:  The fair value of cash and cash equivalents,
marketable equity securities, accounts receivable, accounts payable, other
accrued liabilities and short-term debt approximates their carrying value due to
the short-term nature of these instruments.  Marketable equity securities are
available for-sale equity securities with a cost of $0 at December 31, 1996 and
$3,187,000 at December 31, 1995 and June 30, 1995.  The unrealized gain is
included as a separate component of shareholders' equity.

Long-Term Equity Securities: Equity securities which are classified as long-term
are included as Investment in Vista Gold Corp. in the consolidated balance
sheets. These equity securities were accounted for on the equity method in the
fiscal period ended December 31, 1995 and June 30, 1995 and consequently are
carried at cost basis as adjusted for Atlas's share of Vista's gain or loss and
amortization of the excess cost over the basis in Vista's net assets in the
balance sheets for those years. At December 31, 1996, these securities are
available-for-sale equity securities with a basis of $13,864,000 and are stated
at fair value based upon quoted market prices. The unrealized gain is included
as a separate component of shareholders' equity.

Long-Term Debt:  The fair value of long-term debt is based primarily on the
company's current established refinancing rates of 12%.

The Company has an Amended and Restated Rights Agreement under which a holder of
Preferred Stock Purchase Rights ("Rights") is entitled to purchase from the
Company 1/200th of a share of Series A Preferred Stock at a price of $45 per
1/200th of a share.  Subject to action by the Board of Directors, the Rights
become exercisable upon the occurrence of certain events, including acquisition
by a person or group of 15% or more of the outstanding Common Stock of the
Company.  Upon any such acquisition, the amended Plan provides that upon
exercise of Rights and payment of the purchase price, the exercising Rights
holder is entitled to receive, in lieu of Series A Preferred Stock, shares of
Common Stock having a market value equal to twice the purchase price. The
Amended and Restated Rights Agreement was amended as of September 13, 1993 and
August 15, 1994 to provide that the transactions with Phoenix Financial Holdings
Inc., M.I.M. Holdings Limited and Mackenzie Financial Corporation would not
cause the Rights to become exercisable (Note 20).

8.     EMPLOYEE INCENTIVE PLANS

The Company's Long Term Incentive Plan (the "LTIP") provides that key employees
may be granted options to purchase Common Stock at the fair value of the shares
on the date of grant. At a February 17, 1995 Meeting of Stockholders, the
shareholders approved an amendment to the LTIP (i) to increase by 850,000 to
1,745,000 the number of shares authorized for issuance under the LTIP, (ii) to
provide for the automatic grant to non-employee directors of the Company of
awards of stock options under the LTIP and (iii) to reduce the minimum period
prior to which an option may be exercised for all options granted after January
6, 1995 from one year to six months. Options are exercisable for a maximum of
ten years from the date of grant and no options may be granted after July 31,
1999.

</TABLE> 

The Company has elected to follow Accounting Principles Board Opinion No. 25,
"Accounting for Stock Issued to Employees" (APB 25) and related Interpretations
in accounting for its employee stock options.  Under APB 25, because the
exercise price of the Company's employee stock options equals the market price
of the underlying stock on the date of grant, no compensation expense is
recognized.

During 1996 the Company authorized the grant of options to key personnel for up
to 901,000 shares of the Company's common stock.  Of these, 200,000 were granted
with a two year term, expiring June 21, 1998 and fully vested and exercisable at
time of grant.  Also, there were 100,000 options granted with a two year
term expiring November 5, 1998 and fully vested and exercisable at time of
grant. All remaining options granted have 10 year terms expiring November 1,
2006 and vest and become fully exercisable at the end of six months of continued
employment.  In 1995 the Company granted a total of 763,300 options to key
personnel.

Pro forma information regarding net income and earnings per share as required by
Statement 123, has been determined as if the Company had accounted for its
employee stock options under fair value method of that Statement.  The fair
value for these options was estimated at the date of grant using the Black-
Scholes option pricing model with the following weighted-average assumptions for
1995 and 1996: risk-free interest rate of  5.09%;  dividend yields of 0.0%;
volatility factors of the expected market price of the Company's common stock of
 .462;  and a weighted-average expected life of the option of 4 years.

The Black-Scholes option valuation model was developed for the use in estimating
the fair value of traded options which have no vesting restrictions and are
fully transferable.  In addition, option pricing models require the input of
highly subjective assumptions, including expected stock price volatility.
Because the Company's employee stock options have characteristics significantly
different from those of traded options, and because changes in the subjective
input assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its employee stock options.

For purposes of pro forma disclosures, the estimated fair value of the options
is amortized to expense over the option's vesting period.  The Company's pro
forma information for the years ended December 31, is as follows (in thousands
except for earnings per share)

9.  INVESTMENTS

Investment in Vista Gold Corp.

On August 15, 1994, the Company completed the purchase from M.I.M. (Canada) Inc.
("M.I.M.") of 12,694,200 common shares of Granges Inc. (subsequently changed to
Vista Gold Corp., hereinafter referred to as "Vista" see below) which
represented 37.2% of the issued and outstanding shares of Vista.  The purchase
price was Cdn. $4.00 per share (U.S. $2.80), or an aggregate purchase price of
Cdn. $50.8 million (U.S. $35.8 million).

Vista is a Canadian-based precious metals mining company the shares of which are
traded on the Toronto Stock Exchange and the American Stock Exchange.  Effective
May 1, 1995 Vista amalgamated with Hycroft Resources and Development Corporation
("Hycroft"), which operates the Crofoot/Lewis mine located in Nevada.  Prior to
the amalgamation, Vista had a 50.5% ownership position in Hycroft.  The terms of
the amalgamation called for each common share of Hycroft to be exchanged for
0.88 of a common share of Vista and for each common share of Vista outstanding
prior to the amalgamation, to be exchanged for one common share of Vista.  After
the amalgamation, Atlas continued to hold 12,694,200 shares of Vista,
representing 27.5% of the outstanding common shares.  On May 25, 1995 the
Company purchased 20,700 common shares of Vista which increased the Company's
interest to a total of 12,714,900 common shares.

                                       47
<PAGE>
 
On October 16, 1996 the Company sold 4,240,324 Vista Common shares at $1.32 per
share resulting in a net loss of $1.5 million. The Company continues to hold
8,393,826 Vista common shares, which have been pledged as security for the
Company's $9.81 million Exchangeable Debentures due October 25, 2000 (Note 10).
In October, Vista, known at the time as Granges Inc., amalgamated with Da Capo
Resources Ltd. to form Vista, further reducing the Company's ownership interest
in Vista to 9.6%.

The Company reported the results of Vista's operations on the equity method from
the acquisition date of August 15, 1994 until September 30, 1996.  On October 1,
1996 as a consequence of the sale of the Vista common shares and the
amalgamation with De Capo Resources Ltd., noted above, the Company changed its
method of accounting for the Vista investment to the lower of cost or market
basis.

Summarized Statements of Operations and Balance Sheets of Vista are presented
below.

</TABLE> 

Under the equity method, the Company recorded a loss of  $2,721,000, $1,703,000
and $1,361,000 for the nine months ended September 30, 1996 the six months ended
December 31, 1995 and for the period from August 15, 1994 (date of acquisition)
to June 30, 1995 respectively.

In connection with the May 1, 1995 amalgamation of Vista and Hycroft Resources
and Development Corporation, the Company re-evaluated its investment in Vista
relative to the fair values implied in the amalgamation and to known reserves at
the Crofoot/Lewis mine. As a result, the Company recorded an $11,419,000
impairment of its investment in Vista as of June 30, 1995.  The impairment
reduced the excess cost of the investment over the net assets attributable to
Atlas's interest in Vista from approximately $20.5 million on August 15, 1994
(date of acquisition) to approximately $9 million at June 30, 1995.  The Company
amortized the excess cost of the 

                                       48
<PAGE>
 
investment related to producing properties on a unit of production (gold ounces)
basis which is included in the reported loss discussed above.

Effective September 29, 1995 the Company entered into an exploration joint
venture agreement ("the Agreement") with Vista with respect to approximately 34
square miles of the Company's Gold Bar claim block.  In order to earn a 50%
undivided interest in not more than 15 square miles within the area of interest,
the terms of the Agreement required Vista to spend U.S. $2.25 million on
exploration and development within three years on approximately 1,190 claims
included in the area of interest, at the rate of U.S. $625,000 in each of the
first two years and U.S.$1 million in the third year, and to complete an
independent reserve report recommending development of a deposit containing a
mineable reserve in excess of 300,000 ounces of gold.  Upon execution of the
Agreement, Vista paid the Company $359,000 for reimbursement of past exploration
expenses.  On January 8, 1997 the Company entered into an agreement with Vista
to terminate  the Agreement ("the Termination Agreement") covering the Gold Bar
claim for a total cost of $450,000.  As a result of the Termination Agreement,
Atlas has regained a 100% interest in this portion of the claim block, which
contains the identified Mill Site deposit and the Company's Gold Bar mill, a
3,000 ton per day carbon-in-leach facility located centrally in this portion of
the block.

Investment in Cornerstone Industrial Minerals Corporation.

On November 30, 1995 Atlas purchased 12.2 million (51%) of the outstanding
common shares of Phoenix Financial Holdings Inc. (Phoenix) for an aggregate
purchase price of Cdn. $1,781,200 at which time, Atlas assumed control of the
Phoenix Board of Directors.  At a meeting of the shareholders on September 3,
1996 the shareholders of Phoenix approved a name change to Cornerstone
Industrial Minerals Corporation ("Cornerstone").

On December 13, 1996 Atlas and Cornerstone executed an agreement ("the "Purchase
Agreement") providing for the purchase by Cornerstone of all the issued and
outstanding shares of Atlas Perlite, Inc., Atlas's wholly owned subsidiary the
major asset of which is the Tucker Hill perlite project.  The Purchase Agreement
calls for payment to Atlas of $1 million in cash, 9,647,986 Cornerstone common
shares, the reimbursement of Atlas's Tucker Hill development costs of $2,945,282
and the retention by the Company of a royalty equivalent of 2% of the gross
proceeds generated from the sale of minerals from Tucker Hill.  The purchase
price is payable in three stages as follows:  $125,000 and 1,205,998 shares due
at closing, $500,000 and 4,823,993 shares of common stock upon obtaining all
operating permits and $375,000 and 3,077,994 shares of common stock related to
Atlas assisting the Company in meeting three other milestones which include
obtaining base load perlite contracts for a specified amount of revenues per
year, obtaining permanent project financing and achieving commercial production.
As of December 31, 1996, the Company has met the first two of these stages 
resulting in the Company increasing its ownership percentage to 61%. Upon 
completion of the transaction, the Company will have a 65% equity position in 
Cornerstone.

Investment in Arisur Inc.

On October 8, 1996 the Company acquired Arisur Inc., a Grand Cayman corporation
("Arisur") which owns and operates the Andacaba and the Don Francisco lead, zinc
and silver mines located in southern Bolivia, South America.  The Company
acquired a 50% interest in Arisur from Arimetco International Inc., a Canadian
corporation for $3 million in cash and purchased 100% of Suramco for four
million shares (valued at $3,250,000) of the Company's common stock.  Suramco
owns the remaining 50% interest in Arisur.

                                       49
<PAGE>
 
The acquisition was accounted for as a purchase under generally accepted
accounting principles. Costs of acquisition in excess of Arisur's book value
have been allocated to the mine and mill equipment, the known reserves of Arisur
and the future exploration potential.  The amortization of these costs will be
over the estimated lives of the respective assets, and on the units of
production method for the known reserves.  Exploration potential will be
amortized as reserves are delineated.  The functional currency of Arisur is the
U.S. dollar.


The following are pro forma results of operations as though Arisur had been
acquired as of January 1, 1996 and as of January 1, 1995.

13.  DISCONTINUED OPERATIONS

During fiscal year 1995 the Company recognized income of $621,000 from
discontinued operations, this included a gain of $846,000 recorded upon the
receipt of a payment from the Department of Energy under Title X of the Energy
Policy Act (Note 14) in connection with the reclamation of the 

                                       53
<PAGE>
 
Company's uranium mine and mill site in Moab, Utah. The gain was partially
offset by a loss of $225,000 due to cost overruns at the Company's Coalinga,
California asbestos mine and mill reclamation project (Note 14).

During fiscal year 1994, the Company recognized income of $2,175,000 from
discontinued operations primarily due to the recovery from insurance carriers of
cleanup costs at the Coalinga reclamation project.

The items above are included in the consolidated statements of operations under
the heading "Income from discontinued operations".  The following table
summarizes the operating income (loss) of the discontinued businesses:

14.  COMMITMENTS AND CONTINGENCIES

The Company is obligated to decommission and reclaim its uranium mill site
located near Moab, Utah.  The Company discontinued its uranium operations and
permanently shut down its uranium mill and mines in 1987, estimated shut-down
expenses and reclamation costs of $17,406,000 were accrued.  The balance in this
accrual at December 31, 1996 was $2,705,000.  Title X of "The Comprehensive
National Energy Policy Act" ("Title X"), enacted in October 1992, provides for
the reimbursement of past and future reclamation expenses related to uranium
sites operated under Atomic Energy Commission contracts.  The Company's uranium
reclamation costs are reduced by this Government cost sharing program since 56%
of its tailings were generated under government contracts.  The Company believes
the accrual, when combined with anticipated reimbursements under the Title X
program and the restricted cash used as collateral for the surety, is sufficient
to cover future reclamation costs.

In July 1994, the Company submitted a claim to the Department of Energy (the
"DOE") under Title X for approximately $5 million of reclamation costs incurred
from fiscal year 1986 through fiscal year 1994.  The DOE has given approval on
approximately $4.5 million of the claim and $2.5 million in reimbursement,
disallowing $500,000 pending further substantiation of the claim for
reimbursement.  On December 29, 1994, the Company received $846,000 as a partial
payment of the approved reimbursement which was recorded as income from
discontinued operations.  In June 1995 the Company submitted a second claim to
the DOE under Title X for approximately $3.6 million which included reclamation
costs incurred from fiscal year 1980 through fiscal year 1985, from June 1994
through May 1995 and reclamation costs previously disallowed.  In May 1996 the
Company submitted a third claim for approximately $4,000,000 of costs incurred
from June 1995 through March 1996.  In September 1996 and 1995 the Company
received $816,000 and $1,032,000 as partial payments against the three claims.
These amounts have been added to the 

                                       54
<PAGE>
 
Company's reclamation accrual. Timing of the remaining payments for approved
reimbursements is a function of Congressional appropriation of Title X funding.

During fiscal year 1988, the United States Environmental Protection Agency
notified the Company that it was one of several potentially responsible parties
for cleanup costs at the Company's former asbestos mine and mill site near
Coalinga, California and in the City of Coalinga.  A prolonged period of inquiry
and administrative process concerning this matter followed.

In fiscal years 1995, 1993 and 1991, the Company established a reserve, and
recorded as an expense, $225,000, $600,000 and $3,000,000, respectively, to
cover the Company's share of cleanup costs.  In fiscal year 1992, the Company
began legal action against thirteen insurance carriers which had issued
insurance policies with respect to the site.  During fiscal year 1994, the
Company reached settlement with a number of the carriers and recorded a gain
from discontinued operations of $2,175,000.  All claims with remaining carriers
were settled in fiscal year 1995.  The remedial action plan commenced October
1994 and was completed in 1996.  The Company received EPA's "Approval of
Construction Completion" on November 14, 1996.

Minimum future rental commitments under the Company's non-cancelable operating
leases having a remaining term in excess of one year at December 31, 1996 are as
follows:

Effective March 1, 1997, the Company elected to freeze future benefit accurals
under the plan. Past benefits earned will not be effected by this freeze.

The Company has an Investment and Savings Plan to assist eligible employees in
providing for retirement or other future financial needs. Employee contributions
(up to 10% of their earnings) are matched in Company stock by the Company at a
rate of 100% up to a maximum of 6% of the employee's earnings. In addition, the
Company provides a 4% contribution for all eligible employees compensated on an
hourly scale. The Company's contributions to this Plan in the year ended

December 31, 1996 the six months ended December 31, 1995 and the fiscal years
ended June 30, 1995 and 1994 were $69,000, $34,000, $91,000 and $179,000,
respectively.

16.  OTHER POSTRETIREMENT BENEFIT PLANS

In addition to the Company's defined benefit pension plan the Company has two
defined benefit postretirement plans covering most salaried employees.  One plan
provides medical benefits and the other provides life insurance benefits.  The
postretirement health care plans are contributory, with retiree contributions
adjusted annually, and contain other cost-sharing features such as deductibles
and coinsurance.  The accounting for the health care plans anticipates future
cost-sharing changes to the written plan that are consistent with the Company's
expressed intent to increase the retiree contribution rate annually for the
expected general inflation rate for that year. The life insurance plan is non-
contributory.  The Company's policy is to fund the cost of the postretirement
health care benefits in amounts determined at the discretion of management and
to make annual contributions to the life insurance plan in level amounts over
the plan participant's expected service period.

The following table shows the plan's combined funded status reconciled with the
amounts recognized in the Company's financial statements:

The weighted-average annual assumed rate of increase in per capita cost of
covered benefits (i.e. health care cost trend rate) for the plan is 10% for
fiscal year 1997 and is assumed to decrease gradually to 5% in 2002 and remain
at that level thereafter.

The health care cost trend rate assumption has a significant effect on the
amounts reported. For example, increasing the assumed health care cost trend
rates by one percentage point in each year would increase the accumulated
postretirement benefit obligation for the medical plans as of December 31, 1996,
December 31, 1995 and June 30, 1995 by $29,000, $32,000 and $32,000

respectively, and the aggregate of the service cost and interest cost components
of net periodic postretirement benefit cost for December 31, 1996 by $7,000.

The weighted-average discount rate used in determining the accumulated
postretirement benefit obligation was 7.25%, 7.25% and 7.5% at December 31,
1996, December 31, 1995 and June 30, 1995 respectively.

Deferred income taxes result from temporary differences in the timing of income
and expenses for financial and income tax reporting purposes. The primary
components of deferred income taxes result from exploration and development
costs; depreciation, depletion, and amortization expenses; impairments; and
reclamation accruals.

The net deferred tax balances in the accompanying December 31, 1996, December
31, 1995 and June 30, 1995 balance sheets include the following components:

At December 31, 1996 the Company has unused NOL carryovers of $114,508,000 which
commence expiring in 1998 and investment tax credit (ITC) carryovers of $449,000
which commence expiring in 1997.  The Company also has alternative minimum tax
credit (AMT) carryovers of $127,000 which can be carried forward indefinitely.
These carryovers are subject to restriction due to a change of ownership, as
defined by U.S. tax laws, occurring on October 8, 1996 when the company issued
stock for the acquisition of Arisur (Note 9).  Due to the change of ownership,
utilization of the Company's NOL, ITC and AMT credit carryovers existing as of
October 8, 1996, is limited to offset approximately $930,000 of taxable income
per year.

19. DIFFERENCES BETWEEN U.S. AND CANADIAN GENERALLY ACCEPTED
 ACCOUNTING PRINCIPLES (GAAP)

The Company prepares its consolidated financial statements in accordance with
accounting principles generally accepted in the United States.  These differ in
some respects from those in Canada, as described below.

In accordance with U.S. GAAP, equity securities available for sale are recorded
at fair value with unrealized gains and losses reported as a separate component
of stockholders' equity. Accordingly, unrealized gains and losses in investments
in marketable equitable securities at December 31, 1996 and 1995 have been
recorded as a component of stockholders' equity.  Under Canadian GAAP, such
investments would be recorded at the lower of cost or market.  Therefore, in
conformity with Canadian GAAP, the investments in marketable equity securities
and total stockholders' equity would approximate $13,864,000, $14,694,000,
$3,187,000 and $21,701,000 at December 31, 1996 and December 31, 1995
respectively.

20.  PRIVATE PLACEMENTS

The Company conducted a private placement of 9,090,909 Units of Atlas securities
during the summer of 1994 for a purchase price of $5.50 per Unit, each Unit
consisting of one share of the Company's Common Stock and one-half of a warrant
(exercisable for five years) to purchase a share of the Company's Common Stock
at an exercise price of $7.00 per share in order to finance the acquisition of
12,694,200 common shares of Vista (Note 9) and 1,500,000 Common Shares and
3,100,000 Preferred Shares of Dakota Mining Corporation ("Dakota").  The first
portion of such private placement, consisting of the sale of 6,486,809 Units for
an aggregate purchase price of $35,677,450, was completed on August 15, 1994,
and the proceeds thereof were applied primarily to the cost of the Vista shares.

On October 29, 1994, the Company determined not to proceed with acquisition of
the Dakota shares (see Note 4).  The second portion of the private placement,
the sale of an additional 2,604,100 Units for an aggregate purchase price of
$14,322,550, was completed on December 15, 1994 following the shareholder
approval of an increase in the authorized share capital of the Company. Upon
closing the second portion of the private placement, the Company used a portion
of the proceeds to repay the balance of $800,000 due on a short-term secured
loan.

Of the Units sold in the private placement, Mackenzie Financial Corporation
("Mackenzie Financial") acquired 1,820,000 Units, consisting of 1,820,000 shares
of Common Stock and 910,000 warrants to purchase shares of Common Stock, and
M.I.M. Holdings Limited ("M.I.M.") acquired 2,000,000 Units, consisting of
2,000,000 shares of Common Stock and 1,000,000 warrants to purchase shares of
Common Stock.

On January 18, 1994, the Company sold for $7,500,000 in gross proceeds,
1,500,000 shares of Common Stock for $5.00 per share in a private placement.
The shares were placed outside the United States with a number of gold funds in
Canada and European institutional investors.

On September 20, 1993, the Company sold to Phoenix Financial Holdings Inc. for
an aggregate of $8,375,000 (i) 1,500,000 shares of the Company's Common Stock,
(ii) a Redeemable Convertible Debenture due 1998 in the principal amount of
$3,500,000, which is convertible as to principal into Common Stock at the rate
of $4.00 per share and bears interest at the rate of 9% per annum payable in
cash or Common Stock at the rate of $4.00 per share, and (iii) Warrants to
purchase for three years 2,000,000 shares of Common Stock at $3.625 per share.
Of such securities, the 1,500,000 shares of the Company's Common Stock and
750,000 of the Warrants to Purchase Common Stock were sold to various investors
in a private placement.

REPORT OF INDEPENDENT AUDITORS

THE BOARD OF DIRECTORS AND STOCKHOLDERS OF ATLAS CORPORATION

We have audited the accompanying consolidated balance sheets of Atlas
Corporation and subsidiaries as of December 31, 1996 and 1995 and June 30,
1995, and the related consolidated statements of operations, stockholders'
equity (deficit) and cash flows for the year ended December 31, 1996, the six
months ended December 31, 1995 and the years ended June 30, 1995 and 1994. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits. We did not audit the financial statements of Arisur Inc., a wholly
owned subsidiary, which statements reflect total assets of $7,523,785 as of
December 31, 1996 and total revenues of $578,000 for the year then ended.
Those statements were audited by other auditors whose report has been furnished
to us, and our opinion, insofar as it relates to data included for Arisur Inc.
is based solely on the report of the other auditors.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. 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 and the report of other auditors provide a reasonable
basis for our opinion.

In our opinion, based on our audits and the report of other auditors, the
financial statements referred to above present fairly, in all material respects,
the consolidated financial position of Atlas Corporation and subsidiaries at
December 31, 1996 and 1995 and June 30, 1995, and the consolidated results of
their operations and their cash flows for the year ended December 31, 1996,
the six months ended December 31, 1995 and the years ended June 30, 1995 and
1994, in conformity with generally accepted accounting principles.

The accompanying consolidated financial statements have been prepared assuming
that Atlas Corporation will continue as a going concern. As more fully described
in note 1, the Company has incurred recurring operating losses and has a working
capital deficiency. These conditions raise substantial doubt about the Company's
ability to continue as a going concern. Management's plans in regard to these
matters, which include short-term financing, the sale/joint venture of certain
assets and the start up of Tucker Hill operations are also described in note 1.
The financial statements do not include any adjustments to reflect the possible
future effects on the recoverability and classification of assets or the amount
and classification of liabilities that may result from the outcome of this
uncertainty.

        INVESTMENT AND SAVINGS PLAN. The Atlas Company Investment and Savings
Plan (the "Plan") benefits employees of the Company and its subsidiaries who
have completed six months of service. Each participant under the Plan must be at
least 21 years of age. Under the Plan, an employee may elect to contribute,
pursuant to a salary reduction election, not less than 1 percent and not more
than 10 percent of the employee's annual compensation. The Company makes a
matching contribution of 100 percent of the amount contributed by the employee,
but not more than 6 percent of the employee's annual compensation. In addition,
the Company may make special contributions to the Plan, but these special
contributions may not exceed the maximum amount deductible under Section
404(a)(3)(A) of the Internal Revenue Code of 1986, as amended (the "Code").
Employee contributions may be invested in a number of investment options, but
not Common Stock of the Company. All matching and special contributions to the
Plan are invested in shares of Common Stock of the Company.

        1978 RETIREMENT PLAN. Eligible employees, including officers,
participate in the Atlas Company 1978 Retirement Plan (the "1978 Retirement
Plan"), a noncontributory defined benefit pension Plan. Benefits under the 1978
Retirement Plan are based on years of service and the participant's compensation
during the participant's three consecutive highest compensated years out of the
participant's final five years as a participant. Benefits under the 1978
Retirement Plan are payable upon disability, death or retirement at age 55 or
later and may be distributed in the form of a lump sum, a single-life annuity, a
joint and survivor annuity covering the participant and a beneficiary or
installments over a term of years. Participants retiring before the age of 55
are entitled to a lump sum distribution. Effective March 1, 1997, the Company
froze all future accrual of benefits under the 1978 Retirement Plan. The
benefits earned by each participant as of February 28, 1997 shall be preserved
and no benefit of any participant shall be decreased or reduced. At the
Company's option the freeze can be lifted at any time in the future.

        The following table shows the estimated annual benefits payable upon
retirement in the form of a single-life annuity under the 1978 Retirement Plan
to persons in the specified compensation and years-of-service classifications:

</TABLE>

        Retirement benefits under the 1978 Retirement Plan are based on salaries
and additional compensation such as awards under the Annual Incentive Plan.
These benefits are not affected by directors' fees.

        Benefits listed in the table are net of an offset for part of the
participant's Social Security benefits.  There is no other offset.  Years of
service credited through December 31, 1996 under the 1978 Retirement Plan for
the officers listed in the SUMMARY COMPENSATION TABLE are 6 years for Mr. Davis
and 14 years for Mr. Blubaugh.

        The Code sets limits on a participant's annual benefits on retirement
under the 1978 Retirement Plan. To assure that participants' retirement benefits
are not reduced in the future because of the Code limits, the Board of Directors
adopted a supplemental Executive Retirement Plan, which provides retirement
benefits on an unfunded basis to selected participants whose benefits under the
1978 Retirement Plan would be limited by the Code in an amount equal to the
difference between the annual retirement benefit permitted under the 1978
Retirement Plan by the Code and the amount that would have been paid but for the
limitation imposed by the Code.

        ANNUAL INCENTIVE PLAN. Under the Company's Annual Incentive Plan,
incentive compensation may be paid to key employees selected by the Compensation
Committee based on the achievement by the Company and the selected employees of
performance goals established for each fiscal year by the Compensation
Committee. In addition to target awards, which recognize achievement of the
predetermined goals, the Compensation Committee may establish threshold and
maximum awards to recognize performance which has only been minimally acceptable
and performance which has been significantly above target. Target, threshold and
maximum awards are expressed as a percentage of selected employees' base salary
for the pertinent fiscal year. The Compensation Committee may consider the
adverse impact of external circumstances on the Company's performance in
evaluating the achievement of individual employee goals and in determining
whether to exercise its authority in such

                                      71
<PAGE>
 
circumstances to make alternative or supplemental awards. Since July 1, 1993, no
awards were made under the Annual Incentive Plan.

  (b)     The Registrant filed or amended reports on Form 8-K during the fourth
          quarter of 1996 as follows:

              (i)    Report on Form 8-K dated October 12, 1996 containing the
                     Company's news release with respect to completing the
                     acquisition of Arisur and operating mines in Bolivia.

             (ii)    Report on Form 8-K dated October 18, 1996 containing the
                     Company's press release with respect to electing a Chairman
                     and funding expansion programs of the Company's Bolivia
                     operations.
                     
For purposes of complying with the amendments to the rules governing Form S-8
(effective July 13, 1990) under the Securities Act of 1933, the undersigned
hereby undertakes as follows, which undertaking shall be incorporated by
reference into the Company's Registration Statement on Form S-8 No. 33-18316
(filed on November 3, 1987, as amended by Post Effective Amendment No. 1 filed
on December 15, 1987):

  Insofar as indemnification for liabilities arising under the Securities Act of
  1933 may be permitted to directors, officers and controlling persons of the
  registrant pursuant to the foregoing provisions, or otherwise, the registrant
  has been advised that in the opinion of the Securities and Exchange Commission
  such indemnification is against public policy as expressed in the Securities
  Act of 1933 and is, therefore, unenforceable. In the event that a claim for
  indemnification against such liabilities (other than the payment by the
  registrant of expenses incurred or paid by the director, officer or
  controlling person of the registrant in the successful defense of any action,
  suit or proceeding) is asserted by such

                                      83

<PAGE>
 
     director, officer or controlling person in connection with the securities
     being registered, the registrant will, unless in the opinion of its counsel
     the matter has been settled by controlling precedent, submit to a court of
     appropriate jurisdiction the question whether such indemnification by it is
     against public policy as expressed in the Act and will be governed by the
     final adjudication of such issue.

condition of any character materially and adversely affecting the operations,
prospects or business of Buyer; (vi) any discharge or satisfaction of any Lien,

by or before any court,

                                      22

governmental body or other regulatory or administrative agency or commission,
domestic or foreign, or any arbitration pending, or, to the knowledge of Buyer
after due inquiry, threatened, to which Buyer is a party or by which any of its
assets or properties may be bound or affected, which, if adversely decided would
have a material adverse effect on Buyer; and (ii) by or before any court,
governmental or regulatory agency, or arbitrator, in each case pending or, to
the knowledge of Buyer, threatened, which seeks to restrain, enjoin, prevent the
consummation of, or otherwise challenge this Agreement or any of the

shall mean any action, suit, claim, proceeding, investigation or written
governmental inquiry.

affiliation that Sellers may now or hereafter have with the San Jose mine

                      Indemnification and Related Matters
                      -----------------------------------

     Section 5.1 Indemnification by Sellers. Sellers jointly and severally agree
to indemnify and hold harmless Buyer and its directors, officers and employees
against and in respect of any and all loss, liability, obligation, damage,
deficiency or expense resulting from (a) any misrepresentation, breach of any
warranty or non-fulfillment of any agreement of Sellers under the terms of this
Agreement or in any agreement or certification furnished pursuant hereto; (b)
any claim that Suramco has not fully paid all consideration payable in
connection with its acquisition of the Arisur Shares and the Minera Andacaba
Shares, or that further consideration

                                      26
<PAGE>
 
is payable by Suramco in respect of such Shares; or that Suramco is not the sole
record and beneficial owner of such Shares, in each case free and clear of all
Liens, or that as a result of the transfer of the Arisur Shares and the Minera
Andacaba Shares pursuant to this Agreement, Buyer has not acquired good and
marketable title to such Shares free and clear of all Liens; and (c) any
actions, suits, proceedings, demands, judgments, costs and reasonable legal,
investigatory and other expenses incident to any of the foregoing (regardless of
whether, in the case of third party actions, suits or proceedings, Sellers may
have a meritorious defense). For the avoidance of confusion, it is hereby
stipulated that any information provided by Sellers to Buyer in connection with
the circumstances surrounding the acquisition of the Arisur Shares from Curt and
Ana Maria Goldschmidt shall not relieve Sellers of their obligation under this
Section 5 to indemnify Buyer in full in respect of any and all loss, liability,
obligation, damage, deficiency or expense in respect of any claim that Suramco
has not fully paid all consideration payable in connection with its acquisition
of the Arisur Shares, or that further consideration is payable by Suramco in
respect of such Shares.

     Section 5.2 Indemnification by Buyer. Buyer agrees to indemnify and hold
harmless Sellers against and in respect of any and all loss, liability,
obligation, damage, deficiency or expense resulting from (a) any
misrepresentation, breach of any warranty or non-fulfillment of any agreement of
Buyer under the terms of this Agreement or in any statement or certification
furnished pursuant hereto; and (b) any actions, suits, proceedings, demands,
judgments, costs and reasonable legal, investigatory and other expenses incident
to any of the foregoing (regardless of whether, in the case of third party
actions, suits or proceedings, Buyer may have a meritorious defense).

                                       27
<PAGE>
 
     Section 5.3 Procedure. Promptly after receipt by any person or persons (as
the case may be) that is or are entitled to indemnification under this Section 5
(each, an "Indemnified Party") of notice of the commencement of any action in
respect of which the Indemnified Party will seek indemnification hereunder, the
Indemnified Party shall notify the person obligated to provide such
indemnification (the "Indemnifying Party") thereof in writing, but any failure
to so notify the Indemnifying Party shall not relieve the Indemnifying Party
from any liability that it may have to the Indemnified Party under this Section
5, except to the extent that the Indemnifying Party is prejudiced by the failure
to give such notice. The Indemnifying Party shall be entitled to participate in
the defense of such action and to assume control of such defense with counsel
reasonably satisfactory to such Indemnified Party; provided, however, that:

          (a) the Indemnified Party shall be entitled to participate in the
     defense of such claim and to employ counsel at its own expense to assist in
     the handling of such claim;
          
          (b) the Indemnifying Party shall obtain the prior written approval of
     the Indemnified Party before entering into any settlement of such claim or
     ceasing to defend against such claim, if pursuant to or as a result of such
     settlement or cessation, injunctive or other equitable relief would be
     imposed against the Indemnified Party or the Indemnified Party would be
     adversely affected thereby;
     
          (c) the Indemnifying Party shall not consent to the entry of any
     judgment or enter into any settlement that does not include as an
     unconditional term thereof the giving by each claimant or plaintiff to the
     Indemnified Party of a release from all liability in respect of such claim;
     and

                                      28
<PAGE>
 
          (d) the Indemnifying Party shall not be entitled to control the
     defense of any claim unless within 15 days after receipt of such written
     notice from the Indemnified Party the Indemnifying Party confirms in
     writing its responsibility for such defense and reasonably demonstrates
     that it will be able to pay the full amount of the reasonably expected
     liability in connection with any such claim.

After written notice by the Indemnifying Party to the Indemnified Party of its
election to assume control of the defense of any such action in accordance with
the foregoing, (i) the Indemnifying Party shall not be liable to such
Indemnified Party hereunder for any expenses subsequently incurred by such
Indemnified Party in connection with the defense thereof, and (ii) as long as
the Indemnifying Party is reasonably contesting such action in good faith, the
Indemnified Party shall not admit any liability with respect to, or settle,
compromise or discharge the claim underlying such action without the
Indemnifying Party's prior written consent. If the Indemnifying Party elects to
so participate in or assume the defense of any such action, the Indemnified
Party shall cooperate with the Indemnifying Party in connection with the
defense. If the Indemnifying Party does not assume control of the defense of
such claim as provided in this Section 5, the Indemnified Party shall have the
right to defend and/or settle such claim in such manner as it may deem
appropriate at the cost and expense of the Indemnifying Party, and the
Indemnifying Party will promptly reimburse the Indemnified Party therefor in
accordance with this Section 5. The reimbursement of fees, costs and expenses
required by this Section 5 shall be made by periodic payments during the course
of the investigation or defense, as and when bills are received or expenses
incurred.

     Section 5.4 Related Matters.  (a) Without prejudice to any remedies
available to it by law or otherwise, Buyer shall have the right to offset
against any payments or other consideration payable by it to any Seller or
Sellers after the date of this Agreement pursuant to the terms hereof any claims
that Buyer may have against such Seller or Sellers, for any breach of any
representations, warranties or undertakings.

     (b) In the event that an Indemnifying Party shall be obligated to indemnify
the Indemnified Party pursuant to this Section 5, an Indemnifying Party shall,
upon payment of such indemnity in full, be subrogated to all rights of the
Indemnified Party with respect to the claims to which such indemnification
relates. In the event that an Indemnified Party becomes entitled to any
indemnification from an Indemnifying Party, such indemnification shall be made
in cash upon demand. Sellers shall not be entitled to any contribution or
reimbursement from Suramco, Arisur or Minera Andacaba with respect to payments
made by Sellers under this Section 5.

suits, proceedings, demands, judgments, costs and reasonable legal,
investigatory and other expenses incident to any of the foregoing (regardless of
whether, in the case of third party actions, suits or proceedings, Buyer may
have a meritorious defense).

     Section 5.3  Procedure.  Promptly after receipt by any person that is
entitled to indemnification under this Section 5 (the "Indemnified Party") of
notice of the commencement of any action in respect of which the Indemnified
Party will seek indemnification hereunder, the Indemnified Party shall notify
the person obligated to provide such indemnification (the

                                       21
<PAGE>
 
"Indemnifying Party") thereof in writing, but any failure to so notify the
Indemnifying Party shall not relieve the Indemnifying Party from any liability
that it may have to the Indemnified Party under this Section 5, except to the
extent that the Indemnifying Party is prejudiced by the failure to give such
notice.  The Indemnifying Party shall be entitled to participate in the defense
of such action and to assume control of such defense with counsel reasonably
satisfactory to such Indemnified Party; provided, however, that:

          (a)  the Indemnified Party shall be entitled to participate in the
     defense of such claim and to employ counsel at its own expense to assist in
     the handling of such claim;

          (b)  the Indemnifying Party shall obtain the prior written approval of
     the Indemnified Party before entering into any settlement of such claim or
     ceasing to defend against such claim, if pursuant to or as a result of such
     settlement or cessation, injunctive or other equitable relief would be
     imposed against the Indemnified Party or the Indemnified Party would be
     adversely affected thereby;

          (c)  the Indemnifying Party shall not consent to the entry of any
     judgment or enter into any settlement that does not include as an
     unconditional term thereof the giving by each claimant or plaintiff to the
     Indemnified Party of a release from all liability in respect of such claim;
     and

          (d)  the Indemnifying Party shall not be entitled to control the
     defense of any claim unless within 15 days after receipt of such written
     notice from the Indemnified Party the Indemnifying Party confirms in
     writing its responsibility for such defense and reasonably demonstrates
     that it will be able to pay the full amount of the reasonably expected
     liability in connection with any such claim.

                                       22

After written notice by the Indemnifying Party to the Indemnified Party of its
election to assume control of the defense of any such action in accordance with
the foregoing, (i) the Indemnifying Party shall not be liable to such
Indemnified Party hereunder for any expenses subsequently incurred by such
Indemnified Party in connection with the defense thereof, and (ii) as long as
the Indemnifying Party is reasonably contesting such action in good faith, the
Indemnified Party shall not admit any liability with respect to, or settle,
compromise or discharge the claim underlying such action without the
Indemnifying Party's prior written consent.  If the Indemnifying Party elects to
so participate in or assume the defense of any such action, the Indemnified
Party shall cooperate with the Indemnifying Party in connection with the
defense.  If the Indemnifying Party does not assume control of the defense of
such claim as provided in this Section 5, the Indemnified Party shall have the
right to defend and/or settle such claim in such manner as it may deem
appropriate at the cost and expense of the Indemnifying Party, and the
Indemnifying Party will promptly reimburse the Indemnified Party therefor in
accordance with this Section 5.  The reimbursement of fees, costs and expenses
required by this Section 5 shall be made by periodic payments during the course
of the investigation or defense, as and when bills are received or expenses
incurred.

     Section 5.4  Related Matters.  (a) Without prejudice to any remedies
available to it by law or otherwise, Buyer shall have the right to offset
against any payments or other consideration payable by it to Seller after the
date of this Agreement pursuant to the terms hereof any claims that Buyer may
have against Seller for any breach of any representations, warranties or
undertakings.

                 authorized, executed and delivered by the Seller and
                 constitutes the valid and legally binding obligation of the
                 Seller, enforceable in accordance with its terms and
                 conditions, subject to: (A) bankruptcy, insolvency,

                 instrument.  To the knowledge of the Seller, there is no law,
                 rule or regulation, nor is there any judgment, decree or order
                 of any court or governmental authority binding on Seller or API

                 this Agreement, nor the consummation of the transactions
                 contemplated hereby, will violate (A) the charter or bylaws of
                 the Buyer; (B) any provision of law; (C) any order of any court
                 or other agency of government; (D) any provision of any

                 agreement or other instrument. To the knowledge of the Buyer,
                 there is no law, rule or regulation, nor is there any judgment,
                 decree or order of any court or governmental authority binding
                 on the Buyer which would be contravened by the execution,

                 instrument or agreement required hereunder.

          (v)    Brokers' Fees.  The Buyer has no liability or obligation to pay
                 any fees or commissions to any broker, finder, or agent with
                 respect to the transactions contemplated by this Agreement for
                 which the Seller could become liable or obligated.

                 been and will not be registered under the Securities Act or
                 under any state securities laws. The Buyer is a sophisticated
                 investor with knowledge and experience in business and is not
                 acquiring the API Shares with a view to or for sale in
                 connection with any distribution thereof within the meaning of
                 the Securities Act.

          (vii)  The Common Shares.  The Reorganization was approved by the

                 authorized for issuance and allotted to the Seller and, when

                 shall be validly issued as fully paid and nonassessable, free

<PAGE>
 
                                      10

            an agreement, for the purchase, subscription or issuance of any
            unissued shares of the Buyer, other than as set forth in the
            Financial Statements, or otherwise publicly disclosed or as
            contemplated hereby.

    (viii)  Financial Statements and Reports. The Buyer Financial Statements and
            the notes thereto were prepared in accordance with the books and
            records of the Buyer and fairly present the financial condition and
            results of the operations of the Buyer at the date and for the
            periods covered thereby all in accordance with Canadian generally
            accepted accounting principles consistently applied. None of the
            Buyer Financial Statements contained, as of its date, any untrue
            statement of a material fact or any omission to state a material
            fact required to be stated therein or necessary in order to make the
            statements therein, in light of the circumstances under which they
            were made, not misleading. Each of the balance sheets included in
            the Buyer Financial Statements (including any related notes)
            presents fairly in all material respects the financial position of
            the Buyer as of its date and the Buyer Financial Statements
            (including any related notes) present fairly in all material
            respects the results of operations, changes in financial position,
            cash flows and changes in stockholders' equity, as the case may be,
            of Buyer for the periods therein set forth, subject, in the case of
            unaudited financial statements, to normal year-end audit
            adjustments, in each case in accordance with generally accepted
            accounting principles consistently applied during the periods
            involved (except as otherwise stated therein).

       (ix) No Material Changes. Since June 30, 1996, there has not been, except
            as publicly disclosed or as contemplated hereby,

            (A)   any material adverse change, however caused, in the business,
                  assets, liabilities (actual or contingent), results of
                  operations, prospects, financial or other condition or
                  operations of Buyer;

            (B)   any change in Buyer's authorized or actual equity
                  capitalization;

            (C)   any damage, destruction or casualty loss, materially and
                  adversely affecting the business, assets, liabilities (actual
                  or contingent), results of operations, prospects, or financial
                  or other condition or operations of Buyer, whether or not
                  insured;

            (D)   any incurrence by the Buyer of long-term debt or any other
                  material liability or obligation, actual or contingent, other
                  than current liabilities incurred in the ordinary and usual
                  course of business consistent with past practices;
<PAGE>
 
                                      11


          (E) entry into, or agreement or commitment to enter into, any
              agreement, commitment or transaction by the Buyer (including,
              without limitation, any borrowing, capital expenditure or
              financing or any amendment, modification or termination of any
              existing agreement, commitment or transaction) other than in the
              ordinary and usual course of business consistent with past
              practices;

          (F) acquisition or disposition of, or entry into any agreement by the
              Buyer with respect to the acquisition or disposition of a
              significant amount of assets; or

          (G) any agreement with respect to any of the foregoing.

     warrants to the Buyer that the statements contained in this paragraph 4 are

     this paragraph 4):

     (a)  Organization, Qualification, and Corporate Power. API is a corporation

          operation of the Tucker Hill Property is not in violation of and has
          resulted in no liability (other than liability for compliance with
          existing permits and laws, including but not limited to performance of
          reclamation) under any statute, rule or regulation of any governmental
          authority applicable to the Tucker Hill Property, other than
          violations or liability, if any, which have not resulted and would not
          be reasonably expected to result in any material loss or liability.

              faith to satisfy the requirements of state and federal laws and
              regulations and generally regarded in the mining industry as

          Project taken as a whole. To the knowledge of Seller, there have been
          issued under applicable Environmental Laws no notices of violation or
          consent orders to which API (with respect to its operations at the

          not have a material adverse effect on the Project taken as a whole.
          There are no pending or, to the knowledge of Seller, threatened
          proceedings by or before any court or other governmental authority

          alleged to be, or have been, in violation of, under, any Environmental
          Law, except for such matters as would not have a material adverse
          effect on the Project taken as a whole.

     (k)  Material Contracts and Commitments. A list of all contracts,

          forth in Schedule 4(k). True and correct copies of all of the
          Contracts have been provided by the Seller to the Buyer prior to the
          date hereof. To Seller's knowledge, API has performed all material
          obligations required to be performed by it under the Contracts and is
          not in default, and will not be in default as a result of the

          Contract or any license, judgment, injunction, decree, order,
          determination, restriction, or other instrument to which it is subject
          in connection with the Project, except for such matters as would not
          have a material effect on the Project taken as a whole.

          regulations, except for such violations as would not materially 
          adversely affect the Project.

      (m) Litigation and Claims. To the knowledge of Seller, other than matters
          affecting the U.S. mining industry as a whole, there are no actions,
          suits or proceedings pending or threatened against or affecting the
          Project, including any actions, suits, or proceedings being prosecuted
          by any federal, state, or local department, commission, board, bureau,
          agency, or instrumentality. To the knowledge of Seller, API is not in
          any material default with respect to, or subject to, any order, writ,
          injunction, judgment or decree of any court or any federal, state or
          local department, commission, board, bureau, agency or instrumentality
          which relates to the Project.

     (n)  Consents. API has obtained all consents, approvals, authorizations,
          declarations, or filing required by any federal, state, local, or
          other authority, or any lenders, lessors, creditors, and other third

          taken as a whole.

     (p)  API Financial Statements. The API Financial Statements:

          (A)  have been prepared in accordance with generally accepted
               accounting principles, applied on a basis consistent with that of
               the preceding periods;

          (B)  are complete and accurate in all material respects;

          (C)  accurately disclose the assets, liabilities (whether accrued,
               absolute, contingent or otherwise) and financial condition of API

               and for the periods covered thereby;

          (D)  reflect all proper accruals as at the dates thereof and for the
               periods covered thereby of all amounts which, though not payable

               attributable to activities undertaken during that period; and

          (E)  contain or reflect adequate reserves for all liabilities and
               obligations of API of any nature, whether absolute, contingent or

          1996 as reflected in the API Financial Statements.

     (q)  Undisclosed Liabilities. API has no liabilities (whether accrued,

          except:

               Statements; and

          (B)  liabilities incurred in the ordinary course of business since

      correctly set out and disclose in all respects the financial position of
      API in accordance with good business practice and all financial
      transactions relating to API have been accurately recorded in such books

(dd)  Disclosure. No representation or warranty in this agreement contains any
      untrue statement of a material fact and the representations and warranties

      necessary to make any of the representations or warranties contained

          consents, and approvals of governments and governmental agencies in
          connection with the transactions contemplated by this Agreement.

     (c)  Operation of Business. The Seller will not cause or permit API to

          operations of API, to all premises, properties, personnel, books,
          records (including tax records), contracts, and documents of or
          pertaining to API, which may relate, in the good faith judgment of the
          Buyer, to the titles held by API and to its properties, to the
          financial condition of API, to environmental matters related to API
          and its properties, and to the ore reserve calculations of API. The
          Buyer and Seller hereby acknowledge and agree that the Seller makes no
          representation or warranty as to the reliability, accuracy or
          completeness of any of the information or date referred to in this
          paragraph 5(d). The Buyer (and its Representatives) will treat and
          hold as Confidential Information any and all information received from

          submission of any proposal or offer from any Person relating to the
          acquisition of all or substantially all of the capital stock or assets
          of API (including any acquisition structured as a merger,
          consolidation or share exchange), unless such proposal or offer
          pertains to the Seller as a whole and is made subject to this
          Agreement.

     6.   Post-Closing Covenants.  The Parties agree as follows with respect to 
          the period following the Closing.

     (a)  General.  In case at any time after the Closing any further action 
          is necessary to carry out the purposes of this Agreement, each of the
          parties will take such further actions (including the execution and
          delivery of such further instruments and documents) as any other Party
          reasonably may request, all at the sole cost and expense of the
          requesting Party (unless the requesting Party is entitled to
          indemnification hereunder).

     (b)  Litigation Support.  In the event and for so long as any Party 
          actively is contesting or defending against any third party action,
          suit, proceeding, hearing, investigation, charge, complaint, claim, or
          demand in connection with (i) any transaction contemplated under this
          Agreement or (ii) any fact, situation, circumstance, status,
          condition, activity, practice, plan, occurrence, event, incident,
          action, failure to act, or transaction on or prior to the Closing Date
          involving API, the other Party shall cooperate with it and its counsel
          in the defense or contest, make available its personnel, and provide
          such testimony and access to its books, records and properties as
          shall be necessary in connection with the defense or contest, all at
          the sole cost and expense of the contesting or defending Party (unless
          the contesting or defending Party is entitled to indemnification
          therefor hereunder).

     (c)  Transition.  The Seller will not take any action that is designed or 
          intended to have the effect of discouraging any material lessor,
          licensor, customer, supplier, or other business associate of API from
          maintaining substantially the same business relationships with API
          after the Closing as it maintained with API prior to the Closing.

               detriment (which shall include, but not be limited to, the
               utilization of any tax credits or other tax attributes) for
               periods after the Closing Date or arising from any action or
               failure to act by the Buyer or any Affiliate of the Buyer
               (including API) from and after the Closing, including without

               or similar agreement.

     (e)  Bonding.  For a period not to exceed 90 days (the "Bond Period") 
          following the Closing, the Seller shall maintain full force and effect
          all reclamation and other bonds presently maintained by or for the
          benefit of API. The Buyer's pro rata share (not to exceed 3/12) of all
          actual costs and expenses incurred by the Seller in maintaining such
          bonds shall be included in the amounts to be reimbursed to the Seller
          pursuant to subparagraph 2(b) hereof. As soon as possible following
          the Closing, and in any event within the Bond Period, the Buyer shall

          credit or other financial assurances acceptable to the Bureau of Land
          Management or the other authorities which require or have jurisdiction
          over such bonds.

     (f)  Corporate Records.  As soon as practicable after the Closing Date the 
          Seller shall deliver to the Buyer all corporate records of API which
          are maintained by the Seller or its agents or Affiliates provided that
          the Buyer and the Seller shall coordinate and agree upon a mutually
          acceptable schedule for the assembly and delivery of such documents.
          Following the Closing the Buyer shall afford the Seller reasonable
          access to such documents upon reasonable notice and during regular
          business hours.

          become entitled hereunder and the Buyer will deliver to the Seller
          within 15 days of the end of each calendar month a copy of the
          Internal Financial Statements for the previous month.

          "Buyer Indemnitees") from any and all Environmental Costs
          (collectively "Losses") sought or claimed by any Person, including any
          governmental agency, which are based upon the violation or alleged
          violation by Seller or API of, or liability imposed on Seller or API
          by, any Environmental Law, or relating to the use, treatment,
          handling, storage, disposal or release of Hazardous Substances on or
          in connection with the Project, with respect to all such Losses which
          arise as the result of or in connection with acts, omissions or
          conditions occurring or arising from and after October 24, 1988 (with
          respect to the Tucker Hill Property) and from and after May 1, 1996
          (with respect to the Process Plant Land), up to and including the
          Closing Date, and regardless of whether such Losses arise as a result
          of or on connection with acts, omissions, conditions or occurrences
          which are known to either of the Parties upon the date of this
          Agreement or on the Closing Date. The indemnity for Environmental
          Costs provided for by this subparagraph (7)a constitutes a principal
          element of the consideration for the transactions contemplated by this
          Agreement, and the maximum amount of the Seller's liability under this
          indemnity may exceed the purchase price paid by the buyer for the API
          Shares.


     (b)  Environmental Indemnity to Seller. The Buyer shall indemnify, defend
          and hold harmless the Seller and its Affiliates (collectively the
          "Seller Indemnitees") from any and all Environmental Costs
          (collectively "Losses") sought or claimed by any Person, including any
          governmental agency, which are based upon the violation or alleged
          violation of, or liability imposed by, any Environmental Law, or
          relating to the use, treatment, handling, storage, disposal or release
          of Hazardous Substances on or in connection with any properties or
          assets of API, with respect to all such Losses which arise as the
          result of or in connection with acts, omissions or conditions
          occurring or arising from and after the Closing Date, and regardless
          of whether such Losses arise as a result of or in connection with
          acts, omissions, conditions or occurrences which are known to either
          of the Parties upon the date of this Agreement or on the Closing Date.
          The indemnity for Environmental Costs provided for by this
          subparagraph 7(b) constitutes a principal element of the consideration
          for the transactions contemplated by this Agreement, and the maximum
          amount of the Buyer's liability under this indemnity may exceed the
          purchase price paid by the buyer for the API Shares.

     (c)  Additional Indemnification of Buyer. Seller hereby indemnifies and
          agrees to hold Buyer, its successors and assigns, harmless from and
          against any and all liabilities, claims, damages, losses, or expenses,
          including interest and penalties, reasonable attorneys' fees, and
          other reasonable expenses of defending any actions relating thereto
          (collectively "Losses"), incurred or sustained by Buyer in or as a
          result of or arising out of or attributable to any breach of the
          specific
<PAGE>
 
                                      23
 
          representations and warranties made by Seller herein, or the breach of
          any of the agreements, covenants, conditions, and obligations of
          Seller contained in this Agreement.

     (d)  Additional Indemnification of Seller. Buyer hereby indemnifies and
          agrees to hold Seller, its successors and assigns, harmless from and
          against any and all liabilities, claims, damages, losses, or expenses,
          including interest and penalties, reasonable attorneys' fees and
          other reasonable expenses of defending any actions relating thereto,
          (collectively "Losses"), incurred or sustained by Seller in or as a
          result of or arising out of or attributable to any breach of the
          specific representations and warranties made by Buyer herein, or the
          breach by Buyer of any of the agreements, covenants, conditions, and
          obligations of Buyer contained in this Agreement.

     (e)  Indemnification Procedure. In the case of any claim for
          indemnification brought under this paragraph 7, the Buyer Indemnitee
          or the Seller Indemnitee, (an "Indemnitee") , as the case may be,
          shall give the Buyer or Seller (the "Indemnitor"), as the case may be,
          reasonably prompt notice of the Losses which give rise to such claim;
          provided, however, that the failure to so notify the Indemnitor shall
          not affect the obligation of the Indemnitor to indemnify the
          Indemnitee hereunder unless the Indemnitor shall have been materially
          prejudiced by such failure to so notify. The Indemnitor shall, at its
          option, be entitled to assume the defense of any action, suit or
          proceeding ("Action") related to such claim at its sole cost and
          expense and with counsel reasonably satisfactory to the Indemnitee;
          provided, however, that the Indemnitee shall have the right to
          participate in such defense at its own expense. If the Indemnitor
          fails to defend any Action, any defense by the Indemnitee thereof
          shall be at the sole cost and expense of the Indemnitor. The party
          defending an Action shall control the conduct thereof. The Parties
          agree to make available to each other, their counsel and accountants,
          any information and documents reasonably available to them which
          relate to such Action and their employees, and the Parties hereto
          agree to render to each other such assistance as they may reasonably
          require of each other in order to insure the proper and adequate
          defense of any Action.

          (ii)   the Buyer may terminate this Agreement by giving written notice
                 to the Seller at any time prior to the Closing in the event the
                 Seller has breached any material representation, warranty, or
                 covenant contained in this Agreement in any material respect,
                 the Buyer has notified the Seller of the breach, and the Seller
                 has not disputed the existence or nature of such breach or such
                 breach has not been cured by the Automatic Termination Date; or

          (iii)  the Seller may terminate this Agreement by giving written
                 notice to the Buyer at any time prior to the Closing in the

<PAGE>
 

                                      26


                 occurred, for any reason, before the close of business on the 
                 Automatic Termination Date.

          (c)    Effect of Termination. If either Party terminates this
                 Agreement (or if it terminates automatically) pursuant to this
                 paragraph 10 all rights and obligations of the Parties
                 hereunder shall terminate without any liability of either Party
                 to the other Party except for any liability of any Party then
                 in breach; provided, however, that the confidentiality
                 provisions of paragraph 12 shall survive termination.

     11.  Rescission of Transaction. In the event the Closing occurs prior to
     the Automatic Termination Date but API has not received the Operating

     Seller at any time from the Automatic Termination Date until 5:00 p.m.

     Seller will forthwith (a) return to the Buyer for cancellation any Common
     Shares issued to the Seller hereunder and (b) pay the Buyer an amount equal
     to the aggregate of all cash payments theretofore made to the Seller
     hereunder, together with simple interest calculated at the rate of 10% per
     annum. Subject to the foregoing, all rights and obligations of the Parties
     hereunder shall terminate upon such rescission without any liability of
     either Party to the other Party except for any liability of any Party then
     in breach; provided, however, that confidentiality provisions of paragraph
     12 shall survive such rescission on the same basis as would apply if this
     Agreement had been terminated prior to the Closing.

     12.  Confidentiality. The Buyer acknowledges that any and all information
     concerning the businesses, properties and affairs of API which is disclosed
     to the Buyer or its Representatives by the Seller or its Representatives or
     by API or its Representatives, or which is discovered by the Buyer or its
     Representatives in the course of the due diligence contemplated by
     paragraph 5(d) hereof constitutes the unique, proprietary and confidential
     information of the Seller (collectively "Confidential Information").
     Notwithstanding the foregoing, however, "Confidential Information" shall
     not include any information or data which is in, or becomes a part of, the
     public domain by any means other than the breach by the Buyer or its
     Representatives of the obligations hereunder. Until the earlier to occur of
     the Closing or the second anniversary of the termination of this Agreement
     pursuant to paragraph 10 hereof the Buyer shall maintain all Confidential
     Information disclosed to or received by it pursuant to this Agreement in
     confidence and shall not disclose the same to any third party unless
     required to do so by court order or by law, in which case the Buyer shall
     notify the Seller, in writing, prior to making such disclosure and shall
     cooperate with the Seller to preserve and protect the confidentiality of
     the Confidential Information to the fullest extent possible. Additionally,
     except as specifically contemplated by this Agreement, the Buyer shall not
     utilize any Confidential Information for its own benefit or for the benefit
     of any other party until the earlier to occur of the Closing or the second
     anniversary of the termination of this Agreement in accordance with the
     provisions of paragraph 10 hereof. If this Agreement is terminated, for any
     reason whatsoever, the Buyer and its Representatives will return to the
     Seller all tangible embodiments (and all copies) of the Confidential
     Information which are in their possession.

          written approval of the Buyer and the Seller; provided, however, that
          any Party may make any public disclosure it believes in good faith is
          required by applicable law or any listing or trading agreement
          concerning its publicly-traded securities (in which case the

          prior to making the disclosure).

     (i)    Unresolved Disputes. Any disagreement or dispute arising out of or
            relating to this Agreement, its existence, interpretation,
            performance or enforcement (including but not limited to the
            existence of a default) not resolved by the Parties within fifty
            (50) days after the date on which one party notifies the other of
            any such disagreement or dispute shall be settled by arbitration in
            accordance with this paragraph 13(q).

     (ii)   Rules. Matters subject to arbitration shall be settled by
            arbitration before a panel of three arbitrators in Denver, Colorado,
            in accordance with the commercial arbitration rules of the American
            Arbitration Association in effect at the time of arbitration. In the
            event of a conflict between those commercial arbitration rules and
            this paragraph 13(p), this paragraph 13(p) shall control. The
            judgment of the arbitrators as to such matters shall be binding upon
            the parties to this Agreement, and judgment upon any award rendered
            by the arbitrators may be entered in any court having jurisdiction
            under the provision of the Colorado Revised Statutes pertaining to
            arbitration and award as they may be amended from time to time.

     (iii)  Demand. To demand arbitration any party (the "demanding party")
            shall give written notice to the other party (the "responding
            party"). Such notice shall specify the nature of the issues in
            dispute, the amount involved, and the remedy requested. Within
            twenty (20) days of the receipt of the notice, the responding party
            shall answer the demand in writing, specifying the issues that party
            disputes. The parties shall thereupon each select one arbitrator,
            who shall be qualified by skill and experience in the subject matter
            under dispute. Within fifteen (15) days thereafter, the two
            appointed arbitrators shall jointly select a third arbitrator
            similarly qualified.

     (iv)   Proceedings. Within twenty (20) days after the third arbitrator has
            been selected or appointed, each party to the dispute shall submit
            to the arbitrators a written statement of its position as to the
            matter being arbitrated, including its position on the necessity for
            discovery or a formal hearing. The arbitrators shall, within fifteen
            (15) days after submission of statements, establish a schedule for
            the arbitration proceedings and issues orders relating to the
            conduct of such proceedings, governing, among other matters, the
            extent and nature of any discovery to be allowed and the necessity
            of a formal hearing. If a hearing is held, the arbitrators shall
            issue a decision as to the resolution of the dispute within fifteen
            (15) days after the hearing. A majority ruling by the arbitrators
            shall be binding on the parties. All costs, expenses and fees, plus
            reasonable attorneys' fees, shall be recoverable by or paid to the
            substantially prevailing party in any dispute resolved by
            arbitration.

                             W I T N E S S E T H :
                             - - - - - - - - - -  

     WHEREAS, the Employee has been employed by the Company as its Chairman and
Chief Executive Officer, pursuant to the provisions of an employment agreement
between the Company and the Employee dated September 22, 1993 as the same has
been amended from time to time (the "Employment Agreement"); and

     WHEREAS, the Employee and the Company deem it to be in their mutual
interest that Employee's employment with the Company shall terminate; and

     WHEREAS, the Employee and the Company desire to settle fully and finally
all outstanding matters between them, including, but in no way limited to, any
outstanding matters that might arise out of the Employment Agreement, Employee's
employment with the Company and the termination thereof;

     NOW, THEREFORE, in consideration of the premises and mutual promises herein
contained, it is agreed as follows:

     1.  Termination Date. The parties agree that the Employee's employment by
the Company shall terminate effective as of June 21, 1996 (the "Termination
Date"). Employee understands and agrees that, effective as of the Termination
Date, he is no longer authorized to incur any expenses, obligations or
liabilities on behalf of the Company. Employee acknowledges that he has
submitted, and has been paid in full, for all outstanding expenses incurred or
claimed by him through such date.

     2.  Resignation. The execution of this Agreement shall serve as the
resignation by the Employee as an officer, director and employee of the Company
and of each "Affiliate" of the Company (as that term is defined by Paragraph
15(c) of this Agreement) and as a trustee, fiduciary or administrator of any
employee benefit plan of the Company or an Affiliate, effective as of the
Termination Date.

     3.  Terms of Separation. In consideration of the agreements by Employee
provided herein, including without limitation the release by the Employee in
Paragraph 4 hereof, the Company agrees to provide the following payments and

practicable after this Agreement becomes irrevocable pursuant to the provisions
of Section 10 hereof:]

          (a)  The Company shall pay to the Employee in full satisfaction of any
claims by him against the Company or any Affiliate for salary, bonus, vacation,
holiday, [expense or similar reimbursement,] pension or profit sharing benefits,
separation or severance pay and any other claim for compensation or benefits of
any kind whatsoever under the Employment Agreement or otherwise, (i) a single
lump sum payment of $337,500 (less applicable withholding for payroll and other
taxes), which amount shall be applied in payment of those expenses, advances,
loans, other amounts owed to the Company and its Affiliates and other items
listed in Exhibit D hereto which are presently known to the Company, and (ii) an
additional payment totaling $112,500 to be paid in six equal monthly
installments of $18,750 (less applicable withholdings for payroll and other
taxes), which amount shall be reduced by the amount of any expenses, advances,
loans, other amounts owed to the Company and its Affiliates or similar items
which the Company or its Affiliates may become obligated to pay after the date
hereof but which are not presently known to the Company and its Affiliates. Such
payments shall be made by depositing such amount to the Employee's checking
account or such other account, or by check, as Employee may authorize in
writing.

          (b)  The Company and the Employee agree that any stock options and
restricted stock or other awards which may have been granted to Employee under
the Company's Long Term Incentive Plan are hereby canceled and the Employee
hereby waives any claims to or in respect of such stock options or stock awards.
Immediately following the Termination Date, the Company agrees that it shall
award to Employee an option to purchase an aggregate of 200,000 shares of the
Company's common stock at an exercise price of $1.50 per share, which option
shall be exercisable in whole or in part at any time prior to June 20, 1999. If
not exercised by June 20, 1999, such stock option shall expire. The terms and
conditions of such stock option award shall reflected in a written option
agreement between the Company and the Employee in the form attached hereto as
Exhibit C.

          (c)  The Employee shall be placed on an unpaid personal leave of
absence as an employee through December 18, 1996. During such leave of
absence, Employee shall not have any duties or responsibilities, shall not have

behalf of the Company or to hold himself out as acting for or on behalf of the
Company in any way.

          (d)  The Company shall make available to the Employee through June 20,
1997 coverage under the Company's medical benefits plan for himself and his
dependents under the same terms and conditions, including required
contributions, as apply to active employees. Thereafter, the Employee may
purchase, if eligible, continuation medical benefits coverage to the extent and
for the period provided by federal law.

          (e)  Distributions or payments to Employee shall be made under any 
tax-qualified employee benefit plans of the Company in which the Employee
participated prior to the Termination Date, to the extent provided by such
plans.
 
          (f)  Subject to Employee providing the Company with documentation and
records satisfactory to the Company, the Company agrees to treat certain
Canadian securities trades undertaken by Employee in the name of the Company in

such time as the Company shall receive the proceeds of any such trades, it shall
remit to Employee the net amount received by the Company less all taxes,
expenses, fees and similar charges of any kind which may be incurred by the
Company. Employee represents that such securities trades were undertaken for his
own account and without any prior knowledge by any officer or director of the
Company.

          (g)  In exchange for the release of any and all claims by Employee for
personal and business moving, relocation or similar expenses, and for the other
agreements of the Employee hereunder, the Company agrees to forgive the
repayment of the $60,000 unsecured housing loan, and any accrued but unpaid
interest thereon, which the Company made to the Employee in connection with his
relocation to Denver, Colorado.

claimed to have, or could claim against each or any of the Company Releasees.
Employee hereby agrees to forego any right to file any charges or complaints
with any governmental agencies or a lawsuit against the Company Releasees under
any of the laws referenced in this paragraph or with respect to any matters
covered by the release in this paragraph. Notwithstanding the foregoing, the
release by the Employee in this paragraph shall not limit the right of the
Employee to seek to enforce the provisions of this Agreement.

     5.  Confidentiality and Non-Disclosure Agreements. (a) Employee
acknowledges that any confidentiality, proprietary rights or nondisclosure
agreement(s) in favor of the Company or the Company Releasees, including without
limitation, those agreements contained in Paragraph 7 of the Employment
Agreement, which he may have entered into in connection with his employment
("Nondisclosure Agreement(s)") with the Company, is understood to survive, and
does survive, any termination of such employment, and accordingly nothing in
this Agreement shall be construed as terminating, limiting or otherwise
affecting any such Nondisclosure Agreement(s) or Employee's obligations
thereunder. Without limiting the generality of the foregoing, no time period set
forth in this Agreement shall be construed as shortening or limiting the term of
any such Nondisclosure Agreement(s), which term shall continue as set forth
therein.

     (b)  Employee agrees that, except to the extent compelled by law or legal
process, he (i) will not hereafter disclose or communicate confidential
information of the Company, its Affiliates or their customers to any third party

the Company, its Affiliates and governmental agencies), (ii) will not make use
of confidential information of the Company, its Affiliates or their customersfor
his own behalf, or on behalf of any third party, and (iii) will not facilitate,
assist, persuade or attempt to facilitate, assist or persuade any third party to
commence or prosecute any legal proceedings against the Company, its Affiliates
and their customers and any Company Releasee. In the event Employee receives, is
notified of or is served with a subpoena, summons, complaint, order, notice,
notice of deposition or any other legal process or documents (collectively,

including but not limited to any action at law or equity, arbitral,
administrative proceeding or governmental investigation (collectively,
"Litigation"), relating to the performance of his services as an employee,
officer or director of the Company or its Affiliates or which, if complied with
by Employee, might compel or lead to the disclosure by Employee of confidential
information of the Company, its Affiliates or their customers, the Employee
shall promptly, but in no event later than 2 business days after receipt unless
2 business days is not reasonable under the circumstances, provide the Company
with a copy of the same, and shall in no event and under no circumstances
disclose any such information prior to the last date specified in the Legal
Process for making such disclosure. If the Company wishes Employee to contest
such Legal Process or to be represented by counsel selected by it, the Company
shall as soon as possible, but in no event later than 1 day prior to the date
specified in such Legal Process for complying with the same, (i) notify Employee
in writing that it wishes Employee to contest such Legal
<PAGE>
 

                                      -5-


Process and agree to pay Employee the costs and expenses of attorneys' fees
incurred by the Employee in connection with contesting such Legal Process, not
to exceed $5,000, or (ii) notify Employee that counsel selected by the Company
shall, at the sole expense of the Company, participate in or control the
response of the Employee to such Legal Process insofar as such response relates
to the Employee's performance of services for the Company or the possible
disclosure of confidential information of the Company, its Affiliates or their
customers. Employee agrees to take such lawful action in connection with
contesting any such Legal Process as the Company shall reasonably request from
time to time. Employee agrees to promptly notify the Company of any action taken
or proposed to be taken from time to time in connection with any Legal Process
or Litigation which might lead to the disclosure of the confidential information
of the Company, its Affiliates or their customers, and to make available to the
Company any Legal Process of documents related thereto. The Employee further
agrees to cooperate with the Company by providing a reasonable amount of
testimony relating to any Litigation, to the extent requested by the Company.

except to his immediate family and his legal and tax advisors; provided that
such persons agree to keep such information confidential and not disclose it to
others.

required to enter into this Agreement, that the payments and agreements in this
Agreement are in addition to anything of value to which he is already entitled,

wrongfully with respect to the Employee in connection with his employment by the

payable to Employee under Paragraph 3 hereof, the Company specifically disclaims
any liability to the Employee, and wrongful acts against Employee, on the part

                             EMPLOYEE ANNOUNCEMENT


                                                                   June 21, 1996


TO:       All Employees


FROM:     Gary E. Davis


     Today David Birkenshaw resigned as CEO and Chairman of the Company. As
further discussed in the attached press release which was just released, David
has decided to leave the Company so he can dedicate more time to the pursuit of
other business interests.

     Since David's association with Atlas in 1993, the Company has significantly
strengthened its balance sheet and made several notable acquisitions, including
the Granges control block, the Doby George gold property and the Phoenix public
shell through which we intend to pursue development of industrial minerals.

     Given the ongoing efforts to restart Gold Bar, pending the signing of an
appropriate gold hedging program, and the resulting commitment of both monies
and manpower to this, it was David's opinion that this new direction was
better left to others for implementation.

     I am sure you will join me in thanking David and in wishing him the best in
his new endeavors.

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


TO:       ATLAS CORPORATION (the "Shareholder")


          Granges Inc. ("Granges") and Da Capo Resources Ltd. ("Da Capo")
propose to enter into an agreement (the "Definitive Agreement") providing for
the amalgamation (the "Amalgamation") of Granges and Da Capo to become effective
under the provisions of the British Columbia Company Act (the "Act").

          Under the Amalgamation, each issued and outstanding common share of
Granges will be exchanged for one common share in the capital of the amalgamated
company ("Amalco") and each issued and outstanding common share of Da Capo will
be exchanged for two common shares in the capital of Amalco.

          This letter is intended to set out the terms and conditions of the
agreement of Atlas Corporation (the "Shareholder"): (i) to support the
Amalgamation, including any Alternative Transaction (as defined in section 1.3);
(ii) to vote its common shares (the "Shares") in Granges as set out opposite its
name in Schedule "A" in favour of the Amalgamation and any Alternative
Transaction; and (iii) to abide by the restrictions and covenants set forth
herein.

1.        Shareholder Commitments to the Amalgamation

1.1       Commitment, Non-Solicitation. Subject to the covenants of Granges
herein, the Shareholder covenants that until the date upon which the certificate
is issued under the Act giving effect to the Amalgamation (the "Effective
Date"):
<PAGE>
 
     (a) except to the extent permitted hereunder, the Shareholder will not take
         any steps, directly or indirectly, which may in any way adversely
         affect the transactions contemplated hereby and to be contemplated in
         the Definitive Agreement;

     (b) the Shareholder will not solicit, initiate or encourage submissions,
         proposals or offers from any other person, entity or group relating to,
         or facilitate or encourage any effort or attempt with respect to, the
         acquisition or disposition of all or any substantial part of the issued
         or unissued shares of Granges or Da Capo or their respective
         subsidiaries, or any arrangement, amalgamation, merger, sale of all or
         any substantial part of their respective assets, take-over bid,
         reorganization recapitalization, liquidation or winding-up of, or other
         business combination or similar transaction involving Granges or Da
         Capo or any of their respective subsidiaries and any other party (each
         an "Extraordinary Business Combination"). The Shareholder will not
         participate in any discussions or negotiations regarding, or (except as
         required by law) furnish to any other person, entity or group, any
         information with respect to, or otherwise cooperate in any way with, or
         assist or participate in, any Extraordinary Business Combination. If
         the Shareholder receives any such inquiry, submission, proposal or
         offer, the Shareholder will promptly notify Granges and Da Capo in
         writing of all relevant details relating thereto; and

     (c) the Shareholder will use all reasonable efforts to assist Granges and
         Da Capo to complete the Amalgamation or an Alternative Transaction as
         the case may be.

favour of the Amalgamation at each meeting or adjournment or adjournments
thereof (the "Meeting") of holders of shares of Granges to be held to consider
the Amalgamation.

                                      -2-
<PAGE>
 
1.3       Change In Nature of Transaction. The Shareholder agrees that if
Granges and Da Capo mutually agree that it is necessary or desirable to proceed
with another form of transaction (an "Alternative Transaction") whereby either
Granges or Da Capo or any of their respective affiliates is effectively to
acquire 100% of the Common Shares of the other and merge such entities on
economic terms (including tax treatment) which, in relation to the Shareholder,
are substantially equivalent to or better than those contemplated by the
Agreement, and provided that the consideration paid to shareholders of either
continues to be satisfied in common shares of the other, the Shareholder will
support the completion of such Alternative Transaction in the same manner as the
Amalgamation.

1.4       Meeting of Shareholders. If the Alternative Transaction involves a
meeting or meetings of holders of shares of Granges, the Shareholder agrees to
vote in favour of any matters necessary or ancillary to the completion of the
transactions contemplated by the Alternative Transaction.

1.5       Change of References. In the event of any proposed Alternative
Transaction, the references in this agreement to "Amalgamation" shall be changed
to "Alternative Transaction" and all terms covenants, representations and
warranties of this agreement shall be and shall be deemed to have been made in
the context of the Alternative Transaction. All references to the "Effective
Date" herein shall also refer to the date of closing of the transactions
contemplated by the Alternative Transaction.

1.6       No Dissent. The Shareholder covenants that it will not exercise any
rights of dissent provided under sections 231 and 273 of the Act with respect to
the Amalgamation or any Alternative Transaction.

2.        GENERAL

2.1       Personal Warranties. By executing this Agreement, the Shareholder
represents and warrants to Granges and Da Capo that the Shareholder has the sole
right to vote its Shares at the Meeting.

that it will not during the term of this Agreement transfer or assign or agree

Da Capo, which consent shall not be unreasonably withheld if it is sought for
bona fide tax, planning purposes which does not prejudice, directly or
indirectly, Granges or Da Capo; provided however that such consent is not
necessary if the transfer is (i) to a holding company beneficially owned by the
Shareholder; or (ii) a transfer by the Shareholder, which is a holding company,
to a shareholder who controls the holding company, where such holding company or
shareholder of such holding company, as the case may be, executes this
Agreement.

2.3       Acquired Shares. The Shareholder agrees that any shares of Granges or
Da Capo purchased or as to which the Shareholder acquires beneficial ownership

            AMENDMENT TO RESIGNATION AGREEMENT AND GENERAL RELEASE

          This Amendment to Resignation Agreement and General Release (the
"Amendment") is entered into as of this _____ day of October, 1996 by and
between David J. Birkenshaw ("Birkenshaw") and Atlas Corporation, a corporation
organized under the laws of Delaware ("Atlas").


                                    Recitals
                                    --------

          A.     Birkenshaw and Atlas are parties to the Resignation Agreement
and General Release made and entered into as of June 21, 1996 (the "Agreement").

          B.     Certain disputes and issues have arisen between Birkenshaw and
Atlas concerning the interpretation of, and performance under, the Agreement.

          C.     The parties have agreed to compromise their differences and to
settle their disputes by entering into this Amendment.


                                   Agreement
                                   ---------

          In consideration of the mutual promises contained herein, the parties
incorporate by reference and agree to the accuracy of the above Recitals and
further agree as follows:
<PAGE>
 
     1.   Lump Sum Payment. With regard to Paragraph 3(a) of the Agreement,
Birkenshaw and Atlas agree as follows:

          (a)    In full satisfaction of Atlas's outstanding obligation as of
the date of this Amendment to make monthly installment payments as contemplated
by Paragraph 3(a)(ii) of the Agreement, the parties agree that Atlas shall pay
the amount of $54,000 to Birkenshaw. This amount shall not be reduced by the
amount of any expenses, advances, loans, or other amounts owed to Atlas and its
Affiliates (as that term is defined in the Agreement) which were known to Atlas
as of October 8, 1996. Atlas specifically waives its rights to deduct or
otherwise collect such amounts from Birkenshaw provided, however, that Atlas
specifically reserves and does not waive its right to collect and seek
reimbursement for any such amounts or expenses of which Atlas becomes aware at
any time after October 8, 1996.

          (b)    Birkenshaw warrants and represents that, as of October 1, 1996,
he is a Canadian citizen and resident for tax purposes, and that he is no longer
a United States citizen or resident for tax purposes. In reliance upon this
warranty and representation, Atlas agrees that it will not withhold payroll or
other taxes from the amount to be paid to Birkenshaw pursuant to subparagraph
(a). In the event that any taxing authority treats or attempts to treat that
payment as payment of wages subject to withholding and/or income taxes,
Birkenshaw agrees to pay his own taxes, attorneys' fees, penalties and interest
associated with or
<PAGE>
 
arising from any such treatment or attempted treatment. He further agrees to
indemnify and hold Atlas harmless against any and all amounts (including,
without limitation, taxes, attorneys' fees, penalties and interest), which are
or become due from Birkenshaw or from Atlas to any taxing authority as a result
of this Amendment and the payment provided by the preceding subparagraph.

          (c) Atlas's payment shall be made, within 5 business days after the
date of this Amendment, by depositing such amount as Birkenshaw may direct.

          2. Jones, Gable & Company Limited. With regard to Jones, Gable &
Company Limited ("Jones, Gable"), Birkenshaw and Atlas agree as follows:

          (a) Atlas hereby assigns all of its right, title, interest, and
ownership rights to Jones, Gable Account No. 300202-9 to Birkenshaw. Atlas and
Birkenshaw agree that Paragraph 3 (f) of the Agreement is superseded by the
preceding sentence of this subparagraph. Immediately after the transfer of this
account, Birkenshaw shall apply that account toward partial payment of the
invoice referred to in subparagraph (b).

          (b) Birkenshaw agrees to assume all responsibility, and to hold
harmless and indemnify Atlas, with regard to the March 27, 1996 Jones, Gable
invoice to Atlas in the

                                      -3-

to Jones, Gable within 5 business days after receipt of the payment specified in
subparagraph (c).

          (c) Within 5 business days after the date of this Amendment, Atlas
shall pay Birkenshaw the amount of $6,000 in consideration for his promises set
forth in subparagraphs (a) and (b). This amount is in addition to the amount
referred to in Paragraph 1 of this Amendment.

          (d) Concurrently with the execution of this Amendment, Atlas and
Birkenshaw shall execute a document, in the form of that attached hereto as

(a) and (b). Atlas shall then deliver the original of that document to Jones,
Gable.

          3. Medical Benefits. As of the date of this Amendment, Birkenshaw
hereby waives all right, on behalf of himself and his dependents, to be provided
with coverage under Atlas's medical benefits plan pursuant to Paragraph 3(d) of
the Agreement.

          4. Status. Birkenshaw and Atlas agree to delete Paragraph 3(c) of the

<PAGE>
 
          5. Effect of Agreement. Except to the extent that it has been
specifically modified or amended by this Amendment, the Agreement remains in
full force and effect, and Birkenshaw and Atlas agree that the Agreement and
Amendment, taken together, constitute the entire agreement between the parties
hereto.

in Section 6.2(b)(ii) and (iii) if (A) Employer terminates Executive's
employment hereunder without Cause either prior to 3 months before a Change of
Control Event or more than two years after the last Change of Control Event, or
(B) Executive voluntarily terminates his employment hereunder with Good Reason
either prior to 3 months before a Change of Control Event or more than two years
after the last Change of Control Event. (ii) Prior to the 30th day following the
date of such termination Employer shall pay Executive (A) an amount equal to 
one-twelfth of such Executive's annual rate of base salary that is in effect on
the date of termination multiplied by the number of full years of employment by
the Company, provided that in no event shall such amount be less than one-half
of the amount of Executive's annual base salary in effect on the date of
termination, and (B) all amounts which had accrued but were not paid prior to
such termination for personal services actually rendered before the termination.
(iii) As soon as practicable following the date of such termination, or at such
later date as Executive may validly elect, Employer shall pay Executive all
amounts payable under then existing employee benefit plans and programs.
Notwithstanding the foregoing, if the sum of all of the payments to Executive
whether under this Agreement or otherwise (but excluding any payments which need
not be included in determining if a "parachute payment" has been made within the
meaning of Internal Revenue Code (the "Code") (S) 280G(b)(2)) exceeds the
product of multiplying the Base Amount times 2.99, then such payments hereunder
shall be reduced by the amount of such excess. For purposes of this Agreement,
the term Base Amount is defined in Code (S) 280G(b)(3) and the Treasury
Regulations promulgated thereunder, calculated as of the date required under the
Code.

               (c)  (i) Executive shall be entitled to compensation as specified
in Section 6.2(c)(ii) and (iii) if (A) Employer terminates Executive's
employment hereunder without Cause either (1) within 3 months prior to a Change
of Control Event or (2) upon or after a Change of Control Event but within two
years after the date of that Change of Control Event, or (B) Executive
voluntarily terminates his employment hereunder with Good Reason either (1)
within 3 months prior to a Change of Control Event or (2) upon or after a Change
of Control Event but within two years after the date of that Change of Control
Event. (ii) Prior to the 30th day following the date of such termination
Employer shall pay Executive (A) the amount which equals the Executive's annual
rate of base salary that is in effect on the date of termination, and (B) all
amounts which had accrued but were not paid prior to such termination for
personal services actually rendered before the termination. (iii) As soon as
practicable following the date of such termination, or at such later date as
Executive may validly elect, Employer shall pay Executive all amounts payable
under then existing employee benefit plans and programs. Notwithstanding the
foregoing, if the sum of all of the payments to Executive whether under this
Agreement or otherwise (but excluding any payments which need not be included in
determining if a "parachute payment" has been made within the meaning of Code
(S) 280G(b)(2)) exceeds the Base Amount times 2.99, then such payments hereunder
shall be reduced by the amount of such excess.

<PAGE>
 
               (d)  If Executive's employment hereunder is terminated by
Employer or by Executive under any circumstances other than as set forth in
Section 6.2(a), 6.2(b), or 6.2(c), all payments required by this Agreement shall
cease and the termination shall relieve Employer of its obligations to make any
further payments under this Agreement except payments under the employee benefit
plans and programs and payments of amounts which had accrued but were not yet
paid prior to the termination.

     7.   CONFIDENTIAL INFORMATION AND TRADE SECRETS. Executive acknowledges
that all information possessed by him relating to activities of Employer that is
of a secret or confidential nature, including without limitation financial

is employed by Employer hereunder, and for a period of two years thereafter,
Executive shall not use any such information for the benefit of anyone other
than Employer or disclose any such information to others except in the course of
Employer's business.

     8.   PAYMENT TO ESTATE OR BENEFICIARY. If Executive dies before any
payments required to be paid by Employer to Executive hereunder have been paid,
Employer shall make all such payments to the beneficiary or beneficiaries
designated by Executive in a written notice previously delivered by Executive or
Employer or, in the absence of such a notice, to Executive's estate.

     9.   ARBITRATION. Any and all disputes arising under or relating to this
Agreement shall be subject to mandatory binding arbitration in Denver, Colorado,
before the American Arbitration Association in accordance with its Commercial
Arbitration Rules. Discovery shall be allowed but subject to the limits and
procedures set forth in Rule 26.1 of the Colorado Rules of Civil Procedure. The
prevailing party in any such arbitration proceeding shall be entitled to an
award of his or its reasonable costs and attorney fees.

this Section 10, this Agreement shall be binding upon, inure to the benefit of
and be enforceable by Employer and Executive and their respective heirs, legal
representatives, successors and assigns. If Employer shall be merged into or
consolidated with another entity, the provisions of this Agreement shall be
binding upon and inure to the benefit of the entity surviving such merger or
resulting from such consolidation.

Re:  Withdrawal from Mining Venture Agreement

Dear Gregg:

     Subject to the terms and conditions set forth herein, this letter is
written notice of Granges (U.S.), Inc.'s ("Granges") election to withdraw (the
"Election") from that certain Mining Venture Agreement between Granges and Atlas
Corporation, Atlas Precious Metals Inc. and Atlas Gold Mining Inc.
(collectively, "Atlas") dated as of September 29, 1995 (the "Agreement"). This
Election by Granges is made in accordance with Section 12.1.B. of the Agreement,
which sets forth that Granges' "sole liabilities and responsibilities ...
resulting from or surviving such termination, shall be those set forth in
Sections 5.1(C)(2) and (C)(6), Section 5.2 and Section 5.8." For your
information and without having effect to interpretation of the Agreement, the
preceding recitals pertain to the following issues: *

Section 5.1(C)(2):                       
- -----------------
Granges required to reclaim areas of the Properties disturbed by Granges'
activities, to the extent disturbed by its activities, and shall indemnify Atlas
through completion of reclamation work in accordance with applicable
Environmental Laws for disturbance to the Properties caused by Granges"
Operations under the Agreement.

Section 5.1(C)(6):                             
- -----------------                                                               
After termination of the Agreement, Granges shall have the right of reasonable
access to the Properties in order to complete reclamation of the Properties 
disturbed by Granges' Operations.
- ------------------

/*/Unless defined otherwise in this letter, all capitalized terms shall
have the meanings and definitions provided for them in the Agreement.

Section 5.2:    
- -----------
Granges shall remain responsible for obligations or liabilities to third parties
resulting from its Operations prior to the date of delivery of this letter. 
Further, Granges shall reconvey to Atlas its interst in the Assets by a 
quitclaim deed, free of all liens, claims or other encumbrances arising by, 
through or under Grages. Upon delivery of the quitclaim deed, Granges is 
relieved of liability or obligation to complete its Initial Contribution.
 
Section 5.8:                                                    
- -----------                        
This Section is not applicable since Granges has made this Election prior to 
July 31 of 1997.
                            
     In consideration of Granges' withdrawal from the Agreement, Atlas hereby
agrees to pay to Granges the sum of $450,000, to be paid as follows: $100,000
due not later than five (5) business days after Atlas receives approval by its
Board of Directors for execution of this letter (however in no event beyond
January 10, 1997) with $350,000 to be paid on May 16, 1997. Simple interest in
the amount of eight percent (8%) will be paid on May 16, 1997, calculated on
$350,000 for 150 days. In the event Atlas sells or otherwise disposes of the
Properties prior to May 16, 1997, the $350,000 plus accrued interest shall be
paid to Granges within five (5) days of such a sale of disposition, with
interest prorated to the date of such payment.

     Granges hereby represents to Atlas that Granges' Operations have been
conducted in compliance with the Agreement. Upon Granges' completion of its
reclamation obligations under the Agreement as set forth above, as additional
consideration for the withdrawal of Granges, Atlas hereby agrees to indemnify
and save harmless Granges and its Affiliates from and against all claims,
demands, actions, damages, costs, losses, expenses (including but not limited to
reasonable attorneys' fees) and liabilities which may arise with respect to any
of the Assets or Operations under the Agreement, including but not limited to
those arising under any Environmental Laws in connection with Granges'
Operations under the Agreement, or pertaining to the facilities for processing
of ores at the Atlas Mill Complex, to include the tailings pond associated
therewith; provided, however, that Granges shall indemnify and hold Atlas
harmless from and against any claims, demands, actions, damages, costs, losses,
expenses (including but not limited to reasonable attorneys' fees) and
liabilities that Atlas may incur to third parties as a result of any condition
or event that

constitutes a breach by Granges of its representation in the first sentence of
this paragraph, or as a result of Granges' failure to complete its reclamation
obligations under the Agreement. Atlas' right to bring any action against
Granges based upon this indemnification shall terminate on midnight, Mountain
Standard Time, December 31, 1998.

     The parties understand and agree that, after this notice, Granges' sole
obligations with respect to the Assets shall be: (i) the indemnification of
Atlas, as set forth in the paragraph above; and (ii) filing and recording of the
Deed, as set forth in the paragraph below.

     Upon receipt from you of a fully-executed original of this letter and the
$100,000 payment described above, Granges will immediately proceed to file with
the Nevada State Office of the Bureau of Land Management and to record in Eureka
County, Nevada, with BLM filing fee and county recordation fee to be paid by
Granges, an executed and notarized Deed in the form attached hereto and
incorporated herein by reference, with a proper Exhibit A attached thereto.

     Thank you for your cooperation.

                              Sincerely,

                              GRANGES (U.S.), INC.
