Item 1.    Business1

     GENERAL

     Hecla Mining Company (the Company), originally incorporated in 1891, is
     principally engaged in the exploration, development and mining of precious
     and nonferrous metals, including gold, silver, lead and zinc, and certain
     industrial minerals.  The Company owns or has interests in six precious
     and nonferrous metals properties and five industrial minerals businesses.
     In 1993, the Company's attributable gold and silver production was 60,715
     ounces and 2,974,698 ounces, respectively.  The Company also shipped
     approximately 888,000 tons of industrial minerals products during this
     period, including ball clay, kaolin, feldspar, landscape materials, and
     specialty aggregates.

     The Company's principal producing metals properties include the La Choya
     gold mine, located in Sonora, Mexico, which began operations in January
     1994; the Lucky Friday silver mine, located near Mullan, Idaho, which is a
     significant primary producer of silver in North America; the Republic gold
     mine, located in the state of Washington, historically one of the
     lowest-cost gold operations in North America; and the Greens Creek mine,
     located near Juneau, Alaska, a large polymetallic mine in which the
     Company owns 29.7% interest.  In April 1993, operations at the Greens
     Creek mine were suspended by the manager of the mine in response to
     depressed metals prices.

     The Company's industrial minerals businesses consist of Kentucky-Tennessee
     Clay Company (Ball Clay and Kaolin Divisions), K-T Feldspar Corporation,
     K-T Clay de Mexico, S.A. de C.V., Colorado Aggregate Company of New
     Mexico, and Mountain West Bark Products, Inc.  The Company's industrial
     minerals segment has positioned itself as a leading producer of three of
     the four basic ingredients required to manufacture ceramic and porcelain
     products, including sanitaryware, pottery, dinnerware, electric
     insulators, and tile.  At current production rates, the Company has over
     20 years of proven and probable reserves of ball clay, kaolin and
     feldspar.  During 1993, the industrial minerals businesses provided
     approximately $6.6 million of cash from operations which served to
     partially offset the impact of decreasing gold production from the
     Company's metals segment.

     On December 29, 1993, the Company, two wholly owned Canadian subsidiaries
     of the Company, and Equinox Resources Ltd. (Equinox), a mining,
     exploration and development company, incorporated under the laws of the
     Province of British Columbia and headquartered in Vancouver, Canada,
     executed an Acquisition Agreement providing for the Company's acquisition
     of Equinox.  Pursuant to the Acquisition Agreement and related Plan of
     Arrangement, upon consummation of the transactions contemplated thereby,
     (i) Equinox common shareholders will receive 0.3 common share of the
     Company (Company common shares), for each outstanding Equinox common
     share, (ii) holders of Equinox's Series "A" production participating
     preferred shares will receive





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

           1For definitions of certain  mining terms used in  this
     description, see "Glossary of Certain Mining Terms" at the end of
     Item 1, page 27.

                                      -1-
<PAGE>   3
     newly issued production notes of the Company with the same material terms
     and conditions, and (iii) outstanding Equinox options and warrants will
     become exercisable for Company common shares.  In connection with the
     acquisition of Equinox, the Company expects to issue approximately 6.3
     million Company common shares, including shares issuable upon exercise of
     outstanding options and warrants.

     The Board of Directors of the Company and Equinox have each approved the
     Acquisition Agreement.  On February 25, 1994, the shareholders of Equinox
     also approved the Acquisition Agreement.  However, the transactions
     contemplated by the Acquisition Agreement are subject to a number of
     conditions including, without limitation, approval by a Canadian court of
     the Plan of Arrangement.

     If consummated, the Company will acquire Equinox's primary producing
     property, the American Girl gold mine, located in Imperial County,
     California, which is operated by its joint venture partner MK Gold
     Company.  In addition, the Company believes that Equinox's Rosebud gold
     property, located in Pershing County, Nevada, has significant exploration
     and development potential.

     The Company's strategy is to focus its efforts and resources on the
     development and construction of the Grouse Creek gold project and to
     expand its gold and silver reserves via a combination of acquisition and
     exploration efforts.  During 1994, the Company's most important priority
     will be the timely development and construction of the Grouse Creek gold
     project which is expected to commence production during the fourth quarter
     of 1994.  Additionally, the Company's exploration plan consists primarily
     of exploring for additional reserves and mineralization at or in the
     vicinity of the Republic and La Choya gold mines, the Lucky Friday and
     Greens Creek silver mines and the Grouse Creek gold project.  At the same
     time, the Company will continue to evaluate acquisition and other
     exploration opportunities, primarily in North America, that will
     complement its existing operations.

     The Company's revenues and profitability are strongly influenced by the
     world prices of silver, gold, lead and zinc.  Metals prices fluctuate
     widely and are affected by numerous factors beyond the Company's control,
     including inflation and worldwide forces of supply and demand.  The
     aggregate effect of these factors is not possible to accurately predict.

     Sales of metal concentrates and products are made principally to custom
     smelters and metal traders.  The percentage of revenue contributed by each
     class of product is reflected in the following table:

      La Choya Gold Mine - Sonora, Mexico

      The La Choya gold mine is located 30 miles south of the U.S. border in
      the State of Sonora, Mexico, and is the Company's first operation outside
      the U.S. and Canada.  In May 1992, the Company exercised its option to
      purchase the Mexican mineral concessions related to this property, which
      includes a land position of over 36,000 acres.

      The La Choya gold mine commenced operations in January 1994.  The Company
      expects to produce approximately 63,000 ounces of gold in each of 1994,
      1995 and 1996.  Current proven and probable gold reserves at the La Choya
      gold mine are expected to be substantially depleted in 1996 or early
      1997.

      An exploration drilling program is planned for 1994 to attempt to expand
      the gold reserves at the La Choya gold mine.  The Company believes there
      is the potential to discover additional gold reserves within the mining
      concessions currently controlled by the Company.  The drilling program
      will continue with the objective of expanding the current project and
      extending the life of the mine.

      As of December 31, 1993, the Company has expended approximately $18.8
      million (excluding capitalized interest) on the purchase and development
      of the La Choya gold mine.  Electrical power is provided by on-site
      diesel generators.  The following table presents the proven and probable
      ore reserves for the La Choya gold mine for the periods indicated:

     At December 31, 1993, there were 87 employees at the La Choya gold mine.
     The National Union of Mine, Metallurgical and Related Workers of the
     Mexican Republic is the bargaining agent for the La Choya gold mine
     employees.  The current labor agreement expires on September 7, 1994.

     Grouse Creek Gold Project - Idaho

     The Grouse Creek gold project is located in central Idaho, 27 miles
     southwest of the town of Challis in the Yankee Fork Mining District.
     Mineral rights comprising the Grouse Creek gold project cover 21.4 square
     miles.  The Grouse Creek gold project consists of 18 patented lode mining





                                      -3-
<PAGE>   5
     claims and two patented placer claims, 43 unpatented millsite claims, and
     17 unpatented lode claims for which patent applications are pending.  With
     respect to the 17 unpatented lode claims, the Company has received the
     first half of a Mineral Entry Final Certificate.  Upon certification by a
     United States Federal Mineral Examiner and issuance of patents for these
     claims, all of the current proven and probable reserves at the Grouse
     Creek gold project will be located within patented mining claims.  The
     remainder of the mineral rights in the Yankee Fork Mining District consist
     of 846 unpatented claims.

     The Company acquired these patented and unpatented mining claims as a
     result of its acquisition of CoCa Mines Inc. (CoCa) in 1991.  During 1989
     CoCa purchased the assets of Geodome Resources Limited and its limited
     partner interests in the Grouse Creek project.  As partial consideration,
     CoCa issued 1,023,169 shares of Common Stock valued at $9.5 million and
     472,427 warrants to purchase Common Stock valued at $0.2 million.  In
     addition, CoCa issued promissory notes payable to purchase limited partner
     interests in the Grouse Creek property acquired from Geodome Resources
     Limited (See Note 7 of Notes to Consolidated Financial Statements).

     On February 8, 1994, the Company sold to Great Lakes Minerals, Inc. of
     Toronto (Great Lakes) a 20% undivided interest in the Company's Grouse
     Creek gold project.  Proceeds received from the sale, totaling $13.3
     million, represent the sales price of $6.8 million for 20% of the amount
     spent by the Company on acquisition, exploration and development of the
     project through June 30, 1993, including a fixed premium of $1.25 million,
     plus Great Lakes' pro-rata share of construction costs for Grouse Creek
     from July 1, 1993 through January 31, 1994.  Pursuant to the acquisition
     and joint venture agreements, Great Lakes is required to fund its 20%
     pro-rata portion of remaining capital expenditures required to bring the
     Grouse Creek project to commercial production.  In addition, these
     agreements provide that Great Lakes has the option, at any time prior to
     12 months following the commencement of commercial production at the
     Grouse Creek gold project, to purchase up to an additional 10% undivided
     interest in the project and fund its increased share of capital
     expenditures.

     As of December 31, 1993, the Company and its predecessors had expended
     approximately $54.0 million (excluding capitalized interest) on the
     acquisition, exploration and development of the Grouse Creek project.
     Based on the current mine plan, the Company's share of additional capital
     costs for the project are expected to total approximately $50.0 million in
     1994 and $3.4 million (primarily for equipment) during 1995.  The Company
     currently estimates that production will commence during the fourth
     quarter 1994, with full production achieved in 1995.  The Company
     estimates, that assuming timely commencement of production during the
     fourth quarter, its share of total production at the Grouse Creek gold
     project will be approximately 53,000 gold ounces in 1994 and 106,000 gold
     ounces in 1995.

     Two distinct mineral deposits have been identified at the Grouse Creek
     project:  the Sunbeam deposit and the Grouse deposit, which includes the
     Grouse pit and the Grouse underground high-grade ore zone.

     As a result of drilling programs conducted in 1991 and 1992, the Company
     discovered the Underground Deposit, a high-grade gold ore zone beneath the





                                      -4-
<PAGE>   6
     proposed Upper Grouse Pit, approximately 500 feet below the existing
     surface.  The Underground Deposit is open at depth and has good potential
     to contain additional high-grade ore.

     The Sunbeam deposit was defined by 721 reverse circulation test holes
     totaling 198,097 feet and 22 diamond core drill holes totaling 7,152 feet.
     Test-hole drilling has been completed on an approximate 75-foot grid over
     the Sunbeam deposit.  The deposit is above the water table.  The Upper
     Grouse Pit has been defined by 416 reverse circulation test holes totaling
     175,508 feet and 22 diamond core drill holes totaling 8,488 feet.  The
     higher sections of the deposit are drilled on an approximate 75- to
     100-foot grid.  Portions of the Upper Grouse Pit ore body are below the
     water table.  The deeper high-grade gold ore zone in the Underground
     Deposit has been defined by a reverse circulation test-hole grid pattern
     on approximately 50-foot centers.

     The following table presents the Company's share of the proven and
     probable ore reserves for the Grouse Creek gold project for the periods

              (1)     1993 proven and probable ore reserves reflect only the
                      Company's share (80%) pursuant to the February 8, 1994,
                      sale of a 20% interest in its Grouse Creek project to
                      Great Lakes Minerals, Inc. of Toronto, Canada.

     Pursuant to the mine plan, the Sunbeam Deposit and the Underground Deposit
     are to be mined simultaneously beginning in the fourth quarter of 1994,
     followed by the Upper Grouse Pit.  The mine plan for the Underground
     Deposit proposes a panel cut-and- fill method.  The ore zone is
     approximately 30-feet thick and will be mined in panels 10-feet high and
     20-feet wide.  Cemented backfill will be used to obtain nearly 100%
     extraction of the underground reserve.  Conventional underground mining
     equipment will be used for drilling, blasting, loading, and hauling.  Both
     the Sunbeam Deposit and the Upper Grouse Pit will use conventional surface
     mining methods.  Blasthole assays will be used to determine ore grade
     material.  The material will be segregated and hauled by off-highway
     trucks to the mill.  Waste material will be hauled to a waste storage area
     or will be used as construction material in the tailings dam.  Both
     deposits will mine ore on 20-foot benches.  The milling process involves a
     6,000-ton-per-day gold recovery facility.  The recovery process involves
     crushing and grinding of the ore and recovering approximately 50% of the
     gold in a gravity circuit.  The remaining gold and silver is dissolved in
     a weak





                                      -5-

     sodium cyanide solution and recovered with carbon adsorption and
     Merrill-Crowe precipitation.  Overall recoveries are currently estimated
     at 94% gold and 41% silver for ore from the Sunbeam Deposit, 74% gold and
     64% silver for ore from the Upper Grouse Pit and 95% gold and 85% silver
     from the Underground Deposit.  A refinery on the property will produce
     dore that will be further processed by commercial refiners.  The tailings
     from the cyanide process will be impounded in a 15.5 million ton capacity
     double-lined tailings pond.  All permits for this facility have been
     approved.

     The Sunbeam Deposit will be mined at a rate of 7,700 tons of ore per day
     at a cut-off grade of 0.020 ounce per ton of gold equivalent and a
     stripping ratio of 3.2:1.  The Upper Grouse Pit will be mined at
     approximately the same rate and will have a cut-off grade of 0.031 ounce
     per ton of gold equivalent and a stripping ratio of 5.1:1.  Based upon the
     information developed to date, the Underground Deposit is expected to
     produce 183,000 tons of ore in each of 1994 and 1995 containing
     approximately 96,000 ounces of gold and over 400,000 ounces of silver.
     The Company is currently developing the Underground Deposit.

     Reclamation activities include the partial backfill and revegetation of
     the Sunbeam Deposit and the Grouse Deposit and covering, recontouring and
     revegetating the tailings surface and construction of a permanent
     spillway.  The waste dump and haul roads will be recontoured and
     revegetated.  Process facilities will be removed and foundations will be
     buried.  Concurrent reclamation practices will be employed whenever
     possible.  The reclamation plans have been approved by the appropriate
     state and federal agencies.

     The Company believes that there is excellent potential for extending and
     discovering additional gold reserves at the project including a
     continuation of the high-grade underground mineralization which remains
     unexplored under most of the deposits.  To date, the Company has
     identified 15 exploration targets.  Within the immediate area of the Upper
     Grouse Pit, the Company also believes that there could be additional
     high-grade zones accessible through the underground operations.  An
     exploration program will be undertaken during 1994 to begin to evaluate
     the economic potential of areas below and adjacent to the Upper Grouse
     Pit.

     Lucky Friday Mine - Coeur d'Alene Mining District - Idaho

     The Lucky Friday, a deep underground silver and lead mine, located in
     northern Idaho and 100% owned by the Company, has been a producing mine
     for the Company since 1958.  The mine operated continuously until low
     metals prices and rockburst activity forced the suspension of operations
     in April 1986.  During the shutdown, the Company's engineers began
     converting portions of the mine to a mechanized underhand mining method
     designed to increase productivity and reduce rockburst activity.
     Production was resumed at the Lucky Friday mine in June 1987 and has
     continued uninterrupted since that time.

     The ore-bearing structure at the Lucky Friday mine is the Lucky Friday
     Vein, a fissure vein typical of many in the Coeur d'Alene Mining District.
     The ore body is located in the Revett Formation which is known to provide
     excellent host rocks for a number of ore bodies in the Coeur d'Alene
     District.  The Lucky Friday Vein strikes northeasterly and dips steeply to





                                      -6-
<PAGE>   8
     the south, with an average width of six to seven feet.  The principal ore
     minerals are galena and tetrahedrite, with minor amounts of sphalerite and
     chalcopyrite.  It appears that the ore occurs as a single continuous ore
     body in and along the Lucky Friday Vein.  The major part of the ore body
     has extended from the 1200-foot level to and below the 5660-foot level,
     which is currently being developed.

     The ore produced from the mine is processed in a 1,000-ton-per-day
     conventional flotation mill at a current rate of 700 tons per day at the
     Lucky Friday mine site.  The flotation process produces both a silver-lead
     concentrate and a zinc concentrate.  During 1993 approximately 98% of the
     silver, 97% of the lead, and 86% of the zinc were recovered.  The Company
     believes that adequate provision has been made for disposal of mine waste
     and mill tailings in a manner which complies with current federal and
     state environmental requirements.

     The Lucky Friday mine's mill facility and surface and underground
     equipment are in good working condition.  The mill was originally
     constructed approximately 32 years ago.  The Company maintains and
     modernizes the plant and equipment on an ongoing basis.  Significant
     improvements to the mill include installation of coarse ore feeder bins in
     1982, a new ball mill in 1984, installation in 1989 of a new zinc column
     cell to improve the purity of zinc concentrates, and in 1991, upgrading of
     tailings pumps.  Improvements to the mine include construction of the
     Silver Shaft and installation of a new compressor plant during 1980
     through 1983; installation of a new ventilation system during 1985; and,
     since 1986, construction of a new ore pass system servicing the Silver
     Shaft at the deepest levels of the mine.  The net book value of the Lucky
     Friday mine property and its associated plant and equipment was $28.1
     million as of December 31, 1993.  Washington Water Power Company supplies
     electrical power to the Lucky Friday mine.

     The Lucky Friday silver-lead concentrate product is shipped primarily to
     the ASARCO smelter at East Helena, Montana.  The silver contained in the
     concentrates is returned to the Company under a tolling arrangement.  The
     Company then sells the tolled silver to major metal brokers.  The pricing
     of the silver is based on worldwide bullion markets.  The lead and gold
     contained in the concentrates are sold to ASARCO.  The Lucky Friday zinc
     concentrates are shipped to Cominco's smelter in Trail, British Columbia,
     Canada, and are sold under an agreement with Cominco Ltd.

     In the event agreements with ASARCO and Cominco are terminated, the
     Company believes that new agreements could be negotiated with other
     smelters at terms that would not have a material effect upon the overall
     results of operations or financial condition of the Company.

     Based on the Company's experience in operating deep mines in the Coeur
     d'Alene Mining District, where the persistence of mineralization to
     greater depths may be reliably inferred from operating experience and
     geological data, the Company's policy is to develop new levels at a
     minimum rate consistent with the requirements for uninterrupted and
     efficient ore production.  A new level is developed and brought into
     production only to replace diminishing ore reserves from levels being
     mined out.





                                      -7-
<PAGE>   9
     The length and strength of the ore body have not materially diminished on
     the lowest developed level of the mine.  Based upon this factor, drilling
     data and extensive knowledge of the geologic character of the deposit, and
     many years of operating experience in the Lucky Friday mine and Coeur
     d'Alene Mining District, there are no geologic factors known at present
     which appear to prevent the continuation of the Lucky Friday ore body for
     a considerable distance below the lowermost working level.  Although there
     can be no assurance of the extent and quality of the mineralization which
     may be developed at greater depths, the existing data and operating
     experience justify, in the opinion of the Company's management and based
     upon industry standards, the conclusion that the mineralization will
     extend well below the 6200-foot level, which is the existing bottom of the
     mine's Silver Shaft.

     The principal mining method, underhand cut and fill, was piloted in 1985
     and 1986, and has since been fully implemented.  This method utilizes
     mechanized equipment, a ramp system and cemented sand fill.  The method
     has proven effective in reducing mining costs and limiting rockburst
     activity.  Without this mining method, the mine would be unworkable in
     certain stopes because of the unstable nature of the rock.  However,
     rockbursting continues to be a concern in the one-mile-deep mine.

     reserves, and average cost per ounce of silver produced for the past five
     years is set forth in the table below:

            projected to 100 feet below the lowest level or to one-half
            the exposed strike length, whichever is less, are classified
            as probable reserves.  Mineralization known to exist from
            drill-hole intercepts does not meet the Company's current
            proven or probable reserve criteria and is excluded from these
            reserve categories.


     During 1991, the Company discovered several mineralized structures
     containing some high-grade silver ores in an area known as the Gold Hunter
     property, about 5,000 feet northwest of the existing Lucky Friday
     workings.  In an extensive exploration program in 1992, the Company
     undertook an underground evaluation of the Gold Hunter property
     mineralization.  The program discovered mineralization containing
     significant amounts of silver and lead in an area accessible from the
     4050-foot level of the Lucky Friday mine.  The exploration program and a
     feasibility study were completed during 1993.  The Company's decision
     regarding development of the Gold Hunter property is pending.  The Gold
     Hunter property is controlled by the Company under a long-term operating
     agreement, which entitles the Company, as operator, to a 79.08% interest
     in the net profits from operations from the Gold Hunter properties.  The
     Company will be obligated to pay a royalty after it has recouped its costs
     to explore and develop the properties, which as of December 31, 1993,
     totaled approximately $7.9 million.  If the Gold Hunter property is
     further developed, the Company currently estimates that $10-15 million of
     capital expenditures would be required.

     At December 31, 1993, there were 139 employees at the Lucky Friday mine.
     The United Steelworkers of America is the bargaining agent for the Lucky
     Friday hourly employees.  The current labor agreement expires on June 12,
     1996, and will be continued for an additional three years if the Company
     develops the Gold Hunter property.

     Republic Mine - Republic, Washington

     The Company owns and operates the Republic mine located in the Republic
     Mining District near Republic, Washington, which consists of several
     associated deposits and properties, a mill and ancillary surface plants.
     The property is readily accessible year-round by all-weather roads.  The
     mine produces gold-silver ore which is milled on the property.  Products
     of the mill are a gold-silver flotation concentrate and a gold-silver
     dore.

     The Company's land position in the Republic area consists of approximately
     five square miles, where the Company is currently focusing exploration
     efforts in search of additional gold mineralization.  If additional
     reserves are not discovered and developed, the Company expects that gold
     reserves at the Republic mine will be substantially depleted in early 1995
     and mining operations will cease.  As further described below, the Company
     has undertaken a significant exploration program to determine if there are
     additional reserves on the property.

     The mine is an underground operation using both conventional and
     smaller-scaled mechanized underground mining methods.  Access is provided
     by shafts and a ramp decline.  The ore from the mine is processed in a
     325-ton-per-day flotation and cyanidation mill.  Combined average recovery
     for 1993 in the two mill products (flotation concentrate and dore)
     amounted





                                      -9-
<PAGE>   11
     to 91% of the gold and 80% of the silver contained in the crude ore.  The
     Company believes that adequate provision has been made for disposal of
     mine waste and mill tailings in a manner which complies with current
     federal and state environmental requirements.

     The Republic mine's mill facility and surface and underground equipment
     are in good working condition.  The mill was constructed approximately 57
     years ago.  The Company maintains and modernizes the plant and equipment
     on an ongoing basis.  Significant improvements include, during 1989
     through 1992, expansion of mill capacity, enhanced metals recovery through
     installation of a counter-current decantation circuit, a closed ore
     crushing circuit, an enhanced metals concentrate leaching and
     electrowinning recovery circuit and a small refinery to further enhance
     the value of the mine's products prior to shipment.  Improvements to the
     mine include a decline and development drift which the Company drove
     during 1990 to improve access to mineralized areas, as well as allowing
     direct underground access by rubber-tired vehicles and improving
     ventilation.  The net book value of the Republic mine property and its
     associated plant and equipment is approximately $11.4 million as of
     December 31, 1993.  Ferry County P.U.D. supplies electrical power to the
     Republic mine.

     The mineral-bearing structures in the Republic Mining District are
     dominantly quartz fillings in fissure veins.  Less commonly,
     mineralization is hosted by volcanic and sedimentary wall rocks near the
     veins.  Principal ore minerals are electrum, native gold and silver with a
     variety of sulfosalts and selenides.  The mine has been developed on 13
     levels from the surface to a vertical depth of 1,750 feet.  Since 1984,
     the Golden Promise deposit of the mine has been developed on seven levels.
     Ongoing exploration and development of the Golden Promise deposit are
     complicated by post-ore faulting and by the occurrence of several styles
     of mineralization.  Development drilling during 1993 located several
     ore-grade intercepts 250 feet below the lowest working level of the Golden
     Promise  (See "Exploration" for additional discussion of the Golden
     Promise).

     Flotation concentrates produced from the Company's Republic mill are
     smelted by ASARCO Incorporated at East Helena, Montana.  The silver
     contained in the concentrates is sold directly to ASARCO.  The dore
     product is shipped to Johnson Matthey's refinery at Salt Lake City, Utah,
     for further refining.  The gold contained in the concentrate and the gold
     and silver contained in the dore are then sold by the Company to metal
     brokers, primarily under short-term contracts.  Pricing of silver and gold
     is based on worldwide bullion markets.

     If ASARCO or Johnson Matthey should be unable to receive or process the
     products, the Company believes that other purchasers or processors for the
     products could be found without causing a material effect upon the overall
     results of operations or financial condition of the Company.

     reserves, and average cost per ounce of gold produced for the past five

     (1)   Reserves represent diluted in-place grades and do not reflect losses
           in the recovery processes.  Dilution was effected through
           application of 1.0 feet on either side of the vein for any sample
           thicker than 2.1 feet.  For samples thinner than 2.1 feet, dilution
           was effected with whatever thickness was necessary to equal 4.0
           feet.  Diluent grades are zero ounces per ton for both gold and
           silver.


     In 1993 a negative ore reserve adjustment was made totaling approximately
     39,000 ounces of gold and 235,000 ounces of silver.  Most of the
     adjustment was necessary when development encountered erratic
     mineralization in an upper level ore zone which was previously estimated
     to be continuous reducing the tonnage available for mining by 33,765 tons.
     Other various adjustments attributable to the reduction totaled 867 tons.

     There were 116 people employed at the Republic mine at December 31, 1993.

     Cactus Mine - Mojave, California

     The Cactus mine consists of approximately 1,600 acres of leasehold lands,
     mining claims and millsites, located approximately 85 miles northeast of
     Los Angeles, California, in the Mojave Mining District.  The property is
     readily accessible year-round by all-weather roads.  The Company currently
     has a 63.75% effective interest in Cactus Gold Mines Company (Cactus) and
     manages Cactus' two open-pit heap leach mines, the Middle Buttes and
     Shumake.  The Company, as manager of Cactus, receives a management fee
     equal to 2% of net revenues of Cactus as defined in the mining venture
     agreement and is reimbursed for costs incurred on behalf of Cactus.





                                      -11-
<PAGE>   13
     The Middle Buttes mine began production in August 1986.  During 1991,
     operations were completed at the Middle Buttes mine, and the remaining
     recoverable gold was processed.  Development of the Shumake mine was
     completed in November 1988, with commercial production beginning in
     December 1988.  Mining operations at the Shumake mine were completed in
     February 1992.  The Company's share of gold recovery from the heap is
     estimated to be 3,250 ounces in 1994, which is expected to be the final
     year of production.  Reclamation efforts are ongoing.

     The book value of the Company's interest in the Cactus mine property and
     its associated plant and equipment was fully depreciated as of December
     31, 1993.  Southern CalEdison supplies electrical power to the Cactus
     mine.

     Cactus is owned 75% by Middle Buttes Partners Limited (MBPL) and 25% by
     Compass Mining Inc.  MBPL is a limited partnership in which the Company is
     both the sole general partner (52.50%) and a limited partner (11.25%).
     The Company, as general partner of MBPL, receives 75% of the production
     from Cactus subject to payment of 11.25% of the net cash flows to the
     other limited partner of MBPL.

     The following table sets forth the information with respect to the
     Company's share of production, proven and probable mineral reserves, and
     average cost per ounce of gold produced for the past five years.

      Granduc Mines Limited - British Columbia, Canada

      On January 24, 1994, the Company sold its entire investment in Granduc by
      selling 2,000,000 Granduc common shares to Conwest Exploration Company
      Limited and 815,330 Granduc common shares to Jascan Resources Inc., both
      of which are Toronto, Ontario, Canada based companies.  The Company
      recognized a gain on the sale of approximately $1,327,000 in the first
      quarter of 1994.

      INDUSTRIAL MINERALS SEGMENT

      The Company's principal industrial minerals assets are its ball clay
      operations in Kentucky, Tennessee, and Mississippi; its kaolin operations
      in South Carolina and Georgia; its feldspar operations in North Carolina;
      its clay slurry plant in Monterrey, Mexico; its lawn and garden products
      operations in southern Idaho and western Montana; and its specialty
      aggregate operations (primarily scoria) in southern Colorado and northern
      New Mexico.  The Company conducts these operations through five wholly
      owned subsidiaries:  (1) Kentucky-Tennessee Clay Company (K-T Clay),
      which operates its Ball Clay and Kaolin Divisions; (2) K-T Feldspar
      Corporation (K-T Feldspar), which operates the feldspar business; (3) K-T
      Clay de Mexico, S.A. de C.V. (K-T Mexico), which operates the clay slurry
      plant business; (4) Mountain West Bark Products, Inc. (Mountain West),
      which operates a lawn and garden products business; and (5) Colorado
      Aggregate Company (CAC), which operates the Company's specialty aggregate
      business.

      K-T Clay Ball Clay Division

      K-T Clay is one of the nation's major suppliers of premium ball clay.
      Ball clay is of sedimentary origin and consists of several basic clay
      minerals along with a slight amount of organic content, a combination of
      materials that gives ball clay its unique character.  The principal use
      of ball clay is in the ceramic and porcelain fields, which includes use
      for such items as pottery, dinnerware, tile, electrical insulators and
      sanitaryware.  Ball clay is also used in refractories and abrasives and
      has applications in other specialty industries as well.

      Mining of ball clay is accomplished through strip mining methods.  The
      mining activity requires definition drilling and the removal of
      overburden in order to expose the clay strata to be mined.  Mining
      activity is selective based on clay grade and strata control.  The clays
      are mined with loaders and backhoes, loaded into trucks and hauled to one
      of K-T Clay's plants for processing.  Processing of ball clay consists of
      shredding and classification of clay by various grades, hammer or roller
      milling to reduce particle size, drying and packaging.  The grades can be
      shipped in bulk or blended and bagged in order to meet a particular
      customer's requirements.  A particular clay or blend of several clays can
      also be shipped to customers in slurry form in tanker trucks or rail
      cars.

      There are many grades of ball clay which K-T Clay mines, processes and
      blends to meet the specifications and requirements of its various
      customers.  Different uses may require mixtures of ball clay having
      substantially different physical properties, and K-T Clay, through many
      years of experience and ongoing research performed in its laboratories,





                                      -13-
<PAGE>   15
      possesses the expertise that enables it to respond to changes in customer
      requirements with minimal advance notice.  The marketing of ball clays is
      directed from K-T Clay's headquarters in Mayfield, Kentucky.  K-T Clay's
      marketing personnel are trained in ceramic engineering or related
      technical fields, which also has enabled K-T Clay to respond to changes
      in its customer requirements.

      K-T Clay mines and processes different grades of ball clays in Kentucky,
      Tennessee and Mississippi.  K-T Clay has identified or delineated
      deposits of ball clay on numerous properties.  Such properties are either
      owned in fee simple or held under long-term lease.  The royalties or
      other holding costs of leased properties are consistent with the
      industry, and the expiration of any particular lease would not affect K-T
      Clay's ability to operate at current levels of operations.  K-T Clay has
      sufficient reserve positions to maintain current operations in excess of
      20 years.  K-T Clay is also continuously exploring for new deposits of
      ball clay, either to replace certain grades of clay that may become mined
      out or to locate new deposits that can be mined at lower cost.

      Minimum standards for strip mining reclamation have been established by
      various governmental agencies which affect K-T Clay's ball clay mining
      operations.  The Tennessee Surface Mining Law and the Mississippi
      Geological Economics and Topographical Survey, Division of Mining and
      Reclamation, require K-T Clay to post a performance bond on acreage to be
      disturbed.  The release of the bond is dependent on the successful
      grading, seeding and planting of spoil areas associated with current
      mining operations.  In addition, the United States Environmental
      Protection Agency has issued guidelines and performance standards which
      K-T Clay must meet.  K-T Clay may be required to obtain other licenses or
      permits from time to time, but it is not expected that any such
      requirements will have a material effect upon the Company's results of
      operations or financial condition.

      There were 166 people employed by K-T Clay at its ball clay operations as
      of December 31, 1993.  Some of the hourly employees are represented by
      the United Steelworkers of America.  The three-year labor agreement will
      expire on February 8, 1997.

      K-T Clay Kaolin Division

      K-T Clay acquired the kaolin operations and assets of Cyprus Minerals
      Company's clay division on February 17, 1989, including kaolin mines and
      plants at Deepstep and Sandersville, Georgia, and Aiken, South Carolina.
      Kaolin, or china clay, is a near white clay of sedimentary origin, and is
      consumed in a variety of end uses including ceramic whiteware, textile
      grade fiberglass, as rubber and paper filler, and in miscellaneous
      plastics, adhesives and pigment applications.  Kaolin is a unique
      industrial mineral because of its wide range of chemical and physical
      properties.  The Kaolin Division of K-T Clay mines, processes, and blends
      numerous grades of clay to meet the specifications and requirements of
      its customers.

      Markets for K-T Clay's kaolin products are similar to ball clay and
      adverse shifts in market demand could occur due to mineral substitution
      and





                                      -14-
<PAGE>   16
      decreased demand for end-use products, which could adversely impact the
      demand for kaolin.  Kaolin currently competes with minerals such as
      calcium carbonate in many filler applications, but the substitution of
      other minerals for kaolin in ceramic and fiberglass applications is
      limited.  The marketing of kaolin to the ceramics industry is carried out
      by K-T Clay's sales force.  Marketing to other industries is done through
      sales and distribution agents.

      Mining of kaolin is done by open-pit methods.  Ore bodies are identified
      and delineated by exploration drilling and overburden is removed by
      scrapers down to favorable clay strata.  Select mining of clay is then
      accomplished by backhoe with over-the- road truck haulage to the
      processing and stockpiling facilities.  K-T Clay operates kaolin mines in
      Georgia, serving its processing plants located at Sandersville and
      Deepstep, Georgia.  K-T Clay also operates kaolin mines located in South
      Carolina, serving a processing plant located in Aiken, South Carolina.

      Processing of the clays is completed by the air-floating method where
      clay is shredded, dried, ground and separated by particle size at the
      Sandersville, Deepstep and Aiken locations.  In addition, clay is also
      processed into a water slurry mixture at the Sandersville location.

      K-T Clay's Kaolin Division holds in excess of 20 years of reserves based
      on current sales and product mix.  Reserves are held on fee simple and
      leased property and K-T Clay plans to continue a very active kaolin
      exploration and development program.

      The Kaolin Division operates its mines in Georgia and South Carolina
      under mine permits issued by the Environmental Protection Division,
      Department of Natural Resources of the State of Georgia, and the Land
      Resource Conservation Commission, Division of Mining and Reclamation of
      the State of South Carolina.  All mines and processing plants have
      current permit status and are in good standing.

      There were 92 people employed by K-T Clay at its Kaolin Division as of
      December 31, 1993, with less than 25% of the labor force being
      represented by the Cement, Lime, Gypsum and Allied Workers, Division of
      International Brotherhood of Boilermakers.  The current labor contract at
      the Sandersville, Georgia operation expires on March 1, 1995.

      Both the Ball Clay and Kaolin Divisions of K-T Clay's plants and
      equipment have been operational in excess of 25 years.  The Company has
      upgraded and modernized these facilities over the years and has a
      continuing maintenance program to maintain the plant and equipment in
      good physical and operating condition.  The net book value of the K-T
      Clay property and its associated plant and equipment was $19.1 million as
      of December 31, 1993.  K-T Clay utilizes power from several public
      utilities as well as local utility co-operatives located in the vicinity
      of K-T Clay's operating plants.

      K-T Feldspar Corporation

      The Company acquired the operations and assets of K-T Feldspar on
      December 13, 1990, including sodium feldspar mines and a processing plant
      located near Spruce Pine, North Carolina.  Feldspars are a mineral group





                                      -15-
<PAGE>   17
      that are the major constituents of igneous rocks and important
      constituents of other major rock types.  The feldspars are the most
      widespread mineral group and make up 60% of the earth's crust.
      Chemically the feldspars are aluminosilicates that contain potassium,
      sodium and calcium.

      K-T Feldspar mines, processes and blends sodium feldspar and
      feldspar-silica products.  It also produces by-product mica concentrate
      and construction sand.  K-T Feldspar products are primarily used in the
      ceramic whiteware, glass and paint industries.

      Markets for feldspar have fluctuated slightly over time as a result of
      mature market conditions.  However, adverse shifts in market demand could
      occur due to mineral substitution and decreased demand for end-use
      products.  Feldspar currently competes with nepheline syenite in some
      market segments and substitution between minerals is linked to economics,
      physical-chemical characteristics and supplier reliability.  The
      marketing of feldspar to the ceramics and filler industries is carried
      out by K-T Clay's sales force and through sales and distribution agents.

      Feldspar ore is mined by open-pit methods using a 40-foot bench mining
      plan.  Ore is drilled and blasted, loaded by hydraulic shovel or
      front-end loader into off-highway dump trucks and transported to the
      processing plant.  K-T Feldspar operates several mine locations in the
      Spruce Pine, North Carolina area, all serving the centrally located
      processing plant.  Processing of the feldspar ores consists of crushing,
      grinding, density separation, flotation, drying and high intensity
      magnetic separation.

      K-T Feldspar holds in excess of 20 years of reserves based on current
      sales, product mix and lease terms.  Reserves are held on fee simple and
      leased properties.

      K-T Feldspar operates its mines and plant under permits issued by the
      North Carolina Department of Natural Resources and Community Development.
      All permits are in good standing.

      K-T Feldspar's plant and equipment have been operational in excess of 25
      years.  The Company has upgraded and modernized these facilities over the
      years and has a continuing maintenance program to maintain the plant and
      equipment in good physical and operating condition.  The net book value
      of the K-T Feldspar property and its associated plant and equipment was
      $5.8 million as of December 31, 1993.  Carolina Power & Light Company, a
      regulated public utility, provides the electric power utilized for
      operations at K-T Feldspar.

      There were 44 employees employed by K-T Feldspar as of December 31, 1993;
      none of whom are represented by a bargaining agent.


      K-T Clay de Mexico, S.A. de C.V.

      In 1993, K-T Clay substantially completed construction of its clay slurry
      plant in Monterrey, Mexico, which now supplies clay slurry to the Mexican
      ceramics industry.  Bulk semi-dry clay is shipped by rail from K-T Clay's
      domestic operations to the K-T Mexico slurry plant in Monterrey.  The
      clay





                                      -16-
<PAGE>   18
      is blended to customer specifications and converted to a slurry form for
      final shipment to its customers.

      Approximately $5.8 million was expended in constructing the clay slurry
      plant.  K-T Mexico utilizes electrical power from the local public
      utility.  There were 14 people employed by K-T Mexico as of December 31,
      1993, who are represented by a bargaining agent.

      Mountain West Bark Products, Inc.

      The Company acquired the operations and assets of Mountain West in
      December 1993 (See Note 2 of Notes to Consolidated Financial Statements).
      Mountain West's primary business is the purchasing, processing and
      marketing of certain waste products from lumber milling operations in the
      western intermountain region.  These products are sold as organic soil
      amendments, organic landscape mulches and organic decorative ground cover
      for landscape purposes.

      The waste products are purchased by Mountain West and transported by
      truck for processing to plants at two locations: Rexburg, Idaho and
      Superior, Montana.  The plants are located near the sources of supply to
      reduce trucking costs.  The principal customers are lawn and garden
      retail yards, lawn and garden product distributors and discount retail
      chain stores.  The processing plants are owned by Mountain West and the
      sources of waste bark supply are held under contracts.

      Most of the annual sales take place in the first six months of the year
      due to the seasonality of the market.  The plants have operated in excess
      of 13 years at Rexburg and five years at Superior.  The plants are
      maintained and upgraded continually and are in good working order.

      The net book value of the associated plant and equipment was
      approximately $4.6 million as of December 31, 1993.  Utah Power and Light
      and Montana Power Company provide electrical power utilized by the
      operations at Rexburg and Superior, respectively.

      Mountain West employed 68 employees as of December 31, 1993; none of whom
      are represented by a bargaining agent.

      Colorado Aggregate Company

      CAC mines and sells volcanic rock (scoria) for use as briquettes in gas
      barbecue grills, as landscaping mulch and decorative ground cover, and as
      gravel bedding in aquariums.  Volcanic scoria is a lightweight
      clinker-like material produced during gaseous volcanic eruptions that
      form cinder cones.  These cones occur frequently in the geological
      environment but are unique by density, texture and color.

      The Company operates mines at Mesita, Colorado, and in northern New
      Mexico as well as processing plants at San Acacio and Antonito, Colorado.
      All mining is open pit with minimal requirements for the removal of
      overburden.

      The principal customers for scoria briquettes are manufacturers and

      materials, lawn and garden retailers and discount chain stores are the
      principal customers for scoria landscape stone.

      The Mesita mine is owned by CAC.  Due to the seasonal nature of CAC's
      business, it is usually anticipated that most of its annual sales and
      profits will be generated in the first two quarters of each calendar
      year.  The Company has over 20 years of mineral reserves at the Mesita,
      Colorado, location and has developed in excess of 15 years of mineral
      reserves at the Red Hill mine in northern New Mexico which is under lease
      from the Bureau of Land Management.

      CAC's plants and equipment have been operational in excess of 20 years.
      The Company has upgraded and modernized these facilities over the years
      and has a continuing maintenance program to maintain the plant and
      equipment in good physical and operating condition.  The net book value
      of CAC's property and its associated plants and equipment was $4.0
      million as of December 31, 1993.  Public Service Company of Colorado and
      San Luis Valley Electric Co-operative provide the electric power utilized
      for operations at CAC.

      CAC employed 68 employees as of December 31, 1993; none of whom are
      represented by a bargaining agent.

      SPECIALTY METALS SEGMENT

      Apex Facility - Utah

      Acquired in 1989 from Musto Exploration Ltd., of Vancouver, British
      Columbia, the Apex facility is located in Washington County approximately
      23 miles west of St. George, Utah, on the east flank of the Beaverdam
      Mountains at an elevation of 5,600 feet.  The mine property consists of
      24 patented mining claims and nine unpatented lode mining claims accessed
      by year-round all-weathered roads.  Two of the unpatented lode mining
      claims are leased.  The total surface area covered by the mine properties
      is approximately 700 acres.

      The Apex facility was constructed in 1984 by St. George Mining
      Corporation, a wholly owned subsidiary of Musto Exploration Ltd.  The
      plant and equipment are in good working condition and are maintained on
      an ongoing basis.  Improvements to the plant since the Company acquired
      it in 1989 include redesigning the plant flow sheet, increasing metals
      leaching capacity, the addition of copper and germanium solvent
      extraction circuits, adding copper electrowinning facilities, upgrading
      liners and leak detection systems in the tailings ponds, and constructing
      a tailings neutralization plant.  The net book value of the Apex facility
      property and its associated plant and equipment was $3.0 million as of
      December 31, 1993.  The Apex facility is provided electrical power by
      Utah Power and Light Company.

      The Company suspended mining operations and processing activities at the
      Apex mine in 1990 due to depressed germanium and gallium prices.  Based
      on its periodic review of the status of various mining properties, the
      Company determined in the fourth quarter of 1992 that a write-down of
      approximately $13.5 million was necessary to properly reflect the
      estimated net





                                      -18-
<PAGE>   20
      realizable value of the Apex facility.  There were 26 employees at the
      Apex facility at December 31, 1993; none of whom are represented by a
      bargaining agent.

      Although the Company's strategy has primarily focused on expanding its
      precious metal and industrial mineral operations, the Company continues
      to investigate specialty mineral opportunities for its modern processing
      facility located in southern Utah.  During 1993, the Apex facility
      continued production of cobalt chemicals and process trials of
      metallurgical residues.  The Company believes that it has achieved good
      project performance during 1993 and plans to continue to develop the Apex
      facility to produce cobalt chemicals and specialty metals assuming
      satisfactory economics can be achieved.

      PROPERTIES ON STANDBY

      General

      Various mining operations of the Company have been placed on a standby
      basis.  Placing a mining property on a standby basis during periods of
      depressed metals prices, thereby preserving a depletable asset, is common
      in the mining industry.  The most important of these properties are
      described below.

      Greens Creek Mine - Admiralty Island, Alaska

      At December 31, 1993, the Company held a 29.7% interest in the Greens
      Creek mine, located on Admiralty Island, near Juneau, Alaska, through a
      joint venture arrangement with Kennecott Greens Creek Mining Company, the
      manager of the mine, a wholly owned subsidiary of Kennecott Corporation,
      and CSX Alaska Mining Inc.  Greens Creek is a polymetallic deposit
      containing silver, zinc, gold, and lead.  Effective January 1, 1993, the
      Company increased its interest in the Greens Creek joint venture from
      28.08% to 29.7% when the Company elected its right, under the joint
      venture agreement, to acquire its allocable portion of Exalas Resources
      Corporation's 5.54% joint venture interest offered to the other parties.

      Greens Creek lies within the Admiralty Island National Monument, an
      environmentally sensitive area.  The Greens Creek property includes 17
      patented lode claims, and one patented millsite claim in addition to
      property leased from the U.S. Forest Service.  The entire project is
      accessed and served by 13 miles of road and consists of an ore
      concentrating mill, tailings impoundment, a ship-loading facility and
      ferry dock.

      In February 1993, as a result of depressed metals prices, the decision
      was made by the manager to suspend operations at the Greens Creek mine.
      Commercial production ceased in April 1993, and the mine and mill were
      placed on a standby basis.  Limited mine development activities have
      continued at the mine.  All operating and environmental permits are being
      maintained in anticipation of a resumption of operations once economic
      conditions improve.





                                      -19-
<PAGE>   21
      During operations, ore from the Greens Creek mine, a trackless
      underground operation, is milled at a 1,320-ton-per-day mill at the mine
      site.  The mill produces saleable lead, zinc and bulk lead/zinc
      concentrates.  The three concentrate products were predominantly sold to
      a number of major European and Asian smelters.  A lesser amount of the
      concentrates was sold to metal merchants under short-term agreements.
      The concentrates are shipped from a marine terminal located about nine
      miles from the mine site.

      The Greens Creek mill plant facility and surface and underground
      equipment are in good working condition.  The mill was originally
      constructed about six years ago.  The manager of the joint venture
      maintains the plant and equipment on an ongoing basis.  Improvements to
      the mill during 1992 were directed to increasing mill processing rates
      and improving metals separation capability.  Specific improvements
      included increasing flotation capacity by installing larger float cells
      and column cells and increasing grinding capacity by installing two
      vertical regrinding mills.  The Greens Creek mine uses electrical power
      provided by diesel-powered generators located on-site.  The net book
      value of the Company's interest in the Greens Creek mine property and its
      associated plant and equipment was $49.2 million as of December 31, 1993.

      The Greens Creek deposit consists of zinc, lead, and iron sulfides and
      copper-silver sulfides and sulfosalts with substantial contained gold and
      silver values, having a vein-like to blanket-like form of variable
      thickness.  The ore is thought to have been laid down by an "exhalative"
      process (i.e., volcanic-related rifts or vents deposited base and
      precious metals onto an ocean floor).  Subsequently, the blanket-like
      mineralization was severely folded by several generations of tectonic
      events.

      The estimated mineral reserves for the Greens Creek mine are calculated
      by Greens Creek Mining Company's engineering department with support from
      Kennecott Corporation's technical staff and are not independently
      confirmed by the Company.  Information with respect to the Company's
      share of production, proven and probable mineral reserves, and average
      cost per ounce of silver produced is set forth in the table below:

       1   Operations were suspended in April 1993 and placed on a standby
           basis.

       2   Production commenced in March 1989.


      Ore reserve criteria and estimation techniques used for year-end 1993
      reserves differed substantially from those used in prior years.  Among
      these changes were the adoption of block modeling techniques in place of
      the sectional methods for a major section of the mine, a reevaluation of
      cut-off criteria, and the development of refinements to in-situ net
      smelter return estimates involving projected smelting terms and
      distribution or recovery of metals in the three concentrate products and
      metal price changes.  In addition, more rigorous criteria for reserve
      classification were applied to the probable reserves category.  These
      changes and the deduction for production in 1993 resulted in a reduction
      in proven and probable mineral reserves from 3.4 million tons at December
      31, 1992, to 1.9 million tons at December 31, 1993.

      In 1993, drilling in the southwest area of the mine encountered an
      additional mineralized zone containing higher than mine average gold and
      silver content.  The Company's interest in this mineral-bearing material
      would amount to approximately 840,000 tons at 33.71 ounces of silver per
      ton, 0.27 ounce of gold per ton, 13.36% zinc, and 5.84% lead.  Sufficient
      drilling in the southwest area has not yet been completed to classify the
      mineralized zone as proven and probable mineral reserves.  Drilling is
      expected to continue in 1994 to define the nature and extent of this
      resource.





                                      -21-
<PAGE>   23
      In January 1994, the manager of the Greens Creek mine initiated a
      feasibility study to determine the advisability of placing the mine,
      including the mineral-bearing material of the southwest area, back into
      production.  The feasibility study is expected to be completed during the
      fourth quarter of 1994 or the first quarter of 1995.

      At December 31, 1993 there were 26 employees at the Greens Creek Joint
      Venture.  The employees at the Greens Creek Joint Venture are not
      represented by a bargaining agent.

      Yellow Pine - Idaho

      The Yellow Pine gold mine is located in Valley County, Idaho, about 50
      miles east of McCall in central Idaho, and is accessed by secondary roads
      and air.  The property consists of 26 patented claims which are held by
      the Company under lease from the Bradley Mining Company of San Francisco,
      California, and 57 unpatented claims.  The lease provides for production
      royalties equal to 6% of net smelter returns plus 10% of cumulative cash
      flow, and also provides for a minimum royalty payment of $3,500 per month
      reduced by current production royalties.  Production from the oxide
      mineralization ceased in 1992; the operation has been undergoing
      reclamation since that time.  Mineralized sulfide material, estimated at
      between 15 and 20 million tons containing approximately 0.09 ounce of
      gold per ton, is also located on the property.  The Company continues to
      evaluate the economic feasibility of developing this extensive
      gold-bearing deposit.

      Hog Heaven - Montana

      The Company controls all of the mineral rights and necessary surface
      rights to approximately 6,720 acres known as Hog Heaven, located 25 miles
      south of Kalispell in northwestern Montana.  The property has mineralized
      material totaling approximately 3,886,000 tons containing 0.019 ounce of
      gold per ton and 6.16 ounces of silver per ton.  At present metals
      prices, the Company believes it is uneconomical to bring the property
      into production.

      The Company owns fee simple mineral interests on 6.5 of the 10.5 sections
      it controls.  Approximately 95% of the project's presently known
      mineralization is believed to be contained on those 6.5 sections.  The
      Company leases the remaining 4 sections which are subject to a 5% royalty
      rate.  Three of these sections are also subject to annual advance royalty
      payments of $12,500 for 1991 through 2007 and the remaining section is
      subject to annual rentals of $1,920 per year for 1993-1996.

      The property is subject to two noninterest-bearing production payments.
      The obligation to Canadian Superior Mining Company (U.S.) (Superior) of
      $2,650,000 is payable out of 10% of Hog Heaven net profits after the
      return to the Company, with interest, of all funds invested by it
      subsequent to May 15, 1982.  The second obligation of $1,315,000 payable
      to former partners of a predecessor partnership is also payable out of
      10% of net profits of Hog Heaven and begins after payment in full to
      Superior.

      Based on its periodic review of the status of various mining properties,
      the Company determined in the fourth quarter of 1992 that a write-down of





                                      -22-
<PAGE>   24
      approximately $7.0 million was necessary to properly reflect the
      estimated net realizable value of the Hog Heaven property.

      Escalante Mine - Utah

      The Escalante mine is located in Iron County approximately 40 miles west
      of Cedar City in southwest Utah.  The total surface area covered by the
      mine properties is presently about 800 acres.  The Company ceased mining
      operations at the Escalante mine on December 30, 1988, and the milling of
      stockpiled ore was completed in August 1990.  The currently known ore
      body at the Escalante mine has been mined out and exploration efforts to
      discover more ore have not been successful.  The mill has been placed on
      care-and-maintenance status.

      Lisbon Valley Project - Utah

      The Company leases a block of property comprising approximately 1,100
      acres of private, state and county lands in the Lisbon Valley district
      about 30 miles south of Moab in San Juan County, Utah.  In 1976, the
      Company entered into a joint venture with Union Carbide Corporation (now
      succeeded in interest by Umetco Minerals Corporation, a wholly owned
      subsidiary of Union Carbide) whereby Union Carbide became the operator of
      the property.  The joint venture agreement provides for equal sharing of
      all costs and production.  A second agreement provides for the milling of
      the Company's share of production at Union Carbide's mill.  In December
      1982, the property was placed on a maintenance and standby basis because
      of the depressed markets for uranium and vanadium.  It is fully developed
      and ready for production mining.  However, at current metals prices, the
      Company believes it is uneconomical to place the property into
      production.

      Based on its periodic review of the status of various mining properties,
      the Company determined in the fourth quarter of 1992 that a write-down of
      approximately $3.5 million was necessary to properly reflect the
      estimated net realizable value of the Lisbon Valley Project.

      OTHER INTERESTS

      Uranium Royalties

      The Company receives minimum royalties from certain of its uranium
      properties located in the Ambrosia District near Grants, New Mexico,
      leased by the Company to Rio Algom Corporation, successor to Kerr-McGee
      Corporation.  The leases covering the properties continue in effect so
      long as these royalties are paid, but terminate if defined mining
      operations are not conducted on such properties during a continuous
      period of 36 months.  Although uranium mining operations have been
      suspended on the properties, Rio Algom continues to recover uranium from
      the underground leach solutions from which the Company will continue to
      receive royalties.

      The Company also holds a 2% royalty interest from uranium ores mined from
      certain other properties in the Ambrosia Lake District, which are owned
      by others.





                                      -23-
<PAGE>   25
      The Company does not have current independent or verified mineral reserve
      estimates for any of such properties.  In addition, in view of the
      severely depressed market price for uranium which now exists, uranium
      royalties are immaterial to the operating results of the Company.

      Uranium Mill Tailings

      The Company has been involved in a number of remediation issues related
      to uranium mill tailings located at properties in Colorado and New
      Mexico.  The Company will reclaim a site located near Naturita, Colorado,
      where it processed uranium tailings under a uranium tailings processing
      license originally issued to the Company by the State of Colorado.  The
      Company is currently working with the State of Colorado Department of
      Health to develop a reclamation plan for this site.  During 1993, the
      Nuclear Regulatory Commission terminated the Company's license for a site
      in New Mexico (Johnny M) after successfully completing the required
      reclamation.

      Exploration

      The Company conducts exploration activities from its headquarters in
      Coeur d'Alene, Idaho.  The Company owns or controls patented and
      unpatented mining claims, fee land, mineral concessions, and state and
      private leases in ten states in the U.S.  and two Mexican states.  The
      Company's strategy regarding reserve replacement is to concentrate its
      efforts on (1) existing operations where an infrastructure already
      exists, (2) other properties presently being developed and advanced-stage
      exploration properties that have been identified as having potential for
      additional discoveries, and (3) advanced-stage exploration acquisition
      opportunities.  The Company is currently concentrating its exploration
      activities of existing operations at the Republic and La Choya gold mines
      and the Lucky Friday and Greens Creek silver mines.  The Company is also
      continuing exploration activities at the Grouse Creek gold project.  The
      Company remains active in other exploration areas and is seeking
      advanced-stage acquisition opportunities in the United States, Canada and
      Mexico.

      As part of its strategy to increase its development and expansion of
      currently producing gold properties, the Company continues to focus its
      efforts on the exploration (and development) of the Republic mine.  With
      the completion of the underground decline into the Golden Promise area of
      the mine, the Company has secondary access to that area as well as a base
      for further exploration.  The Company has already identified numerous
      gold targets through a surface and underground drilling program and is
      currently working to access these targets from the underground decline.
      For other activities at the mine see "Metals Segment - Republic Mine -
      Republic, Washington."

      In February 1992, the Company discovered several mineralized structures
      located about 5,000 feet northwest of the existing Lucky Friday mine
      workings in an area referred to as the Gold Hunter.  An exploration and
      development program to determine the size, content and economic
      feasibility of mining the mineralization continued during 1992 and was
      completed in 1993.  The Company's decision regarding development of the
      Gold Hunter is pending (See "Metals Segment - Lucky Friday Mine - Coeur
      d'Alene Mining District - Idaho" for additional discussion regarding the
      Gold Hunter).

      Assuming the consummation of the planned acquisition of Equinox in March
      1994, the Company believes there are significant exploration and
      development opportunities at the Rosebud gold property located in
      Pershing County, Nevada.  Additionally, the Equinox acquisition will also
      bring the American Girl gold mine, located in Imperial County,
      California, and a host of other exploration properties.

      Properties are continually being added to or dropped from this inventory
      as a result of exploration and acquisition activities.  Exploration
      expenditures for the three years ending December 31, 1993, 1992 and 1991
      were approximately $4.4 million, $7.7 million and $5.7 million,
      respectively.

      INDUSTRY SEGMENTS

      Financial information with respect to industry segments is set forth in
      Note 11 of Notes to the Consolidated Financial Statements.

      COMPETITION

      The Company is engaged in the mining and processing of gold, silver and
      other nonferrous metals and industrial minerals in the United States.
      The Company encounters strong competition from other mining companies in
      connection with the acquisition of properties producing, or capable of
      producing, gold, silver and industrial minerals.  The Company also
      competes with other mining companies in connection with the recruiting
      and retention of qualified employees knowledgeable in mining operations.
      Silver and gold are worldwide commodities and, accordingly, the Company
      sells its production at world market prices.  The table below reflects
      the volatility of silver and gold prices:

</TABLE>


     The Company cannot compare sales from its ball clay mining operations with
     sales of other ball clay producers because the principal competitors are
     either family-owned or divisions of larger, diversified companies, but the
     Company believes that K-T Clay is the largest producer of ball clay in the
     United States.  With the acquisition of kaolin assets from Cyprus Minerals
     Company in 1989, the Company has also become an important producer in the
     United States of ceramic-grade kaolin.  The principal competitors of the
     Company in the ball clay industry are H. C. Spinks Clay Company, Watts
     Blake Bearne & Company, and Old Hickory Clay Company.  The principal
     competitors of the Company in the kaolin industry, are Albion Kaolin
     Company, Evans Clay Company, JM Huber Corporation, English China Clay
     Company and Dry Branch Kaolin Company.  The Company, with the acquisition





                                      -25-
<PAGE>   27
     of Indusmin Incorporated's feldspar assets, is also a major producer and
     supplier of sodium feldspar products.  The principal competitors of the
     Company in the feldspar industry are Feldspar Corporation and Unimin
     Corporation.

     The Company competes with other producers of scoria and with manufacturers
     of ceramic briquettes in the production and sale of briquettes.  The
     Company has limited information as to the size of the barbecue briquette
     industry, but believes that it supplies a major portion of the scoria
     briquettes used in gas barbecue grills.  Price and natural product
     characteristics, such as color, uniformity of size, lack of contained
     moisture and density, are important competitive considerations.  The
     Company believes that it has a significant portion of the landscape scoria
     market east of the Continental Divide.

     Mountain West competes with other producers of lawn and garden and soil
     products, decorative bark products and landscape mulches.  The principal
     competitors are either privately owned companies or divisions of larger
     diversified companies that operate in numerous regional markets.  The
     Company has limited information about the sales of competing products in
     its overall markets but believes it supplies a significant portion of the
     market for its product in the intermountain region.

     With respect to the acquisition of mineral interests and exploration
     activities, which in terms of continuing growth and success may be the
     most important area of the Company's activities, the Company competes with
     numerous persons and with companies, many of which are substantially
     larger than the Company and have considerably greater resources.

     SAFETY AND ENVIRONMENTAL REGULATION

     The mining operations of the Company are subject to inspection and
     regulation by the Mine Safety and Health Administration of the Department
     of Labor (MSHA) under provisions of the Federal Mine Safety and Health Act
     of 1977.  It is the Company's policy to comply with the directives and
     regulations of MSHA.  In addition, the Company takes such necessary
     actions as, in its judgment, are required to provide for the safety and
     health of its employees.  MSHA directives have had no material adverse
     impact on the Company's results of operations or financial condition, and
     the Company believes that it is substantially in compliance with the
     regulations promulgated by MSHA.

     The Company's operations are also subject to regulation under various
     federal and state environmental laws and regulations.  The most
     significant of these laws deal with mined land reclamation, waste water
     discharges and solid wastes from mines, mills, and further processing
     operations (see Note 8 of Notes to Consolidated Financial Statements).
     The Company does not believe that these laws and regulations have a
     material adverse effect on its results of operations or financial
     condition at this time.  However, charges by smelters to which the Company
     sells its metallic concentrates and products have substantially increased
     over a period of years because of requirements that smelters meet revised
     environmental quality standards.  Smelters are also subject to
     environmental protection laws and regulations.  The Company has no control
     over the smelters' operations or their





                                      -26-
<PAGE>   28
     compliance with environmental laws and regulations.  If the smelting
     capacity of the United States was significantly further reduced because of
     environmental requirements, it is possible that the Company's operations
     could be adversely affected.

     While the Company believes that it is in substantial compliance with
     current applicable environmental regulations, changes in federal and state
     regulatory policies may, at some future date, impose additional costs and
     operating requirements upon the Company.  In addition, the future
     development of other Company holdings may require the acquisition of
     permits from various governmental agencies.  Such future changes in
     federal and state regulatory policies on the Company's exploration and
     development activities could adversely affect the Company.

     EMPLOYEES

     As of December 31, 1993, the Company and its subsidiaries employed 919
     people.

     GLOSSARY OF CERTAIN MINING TERMS

     BALL CLAY -- A fine-grained, plastic, white firing clay used principally
     for bonding in ceramic ware.

     CASH PRODUCTION COSTS -- Includes all direct and indirect operating cash
     costs incurred at each operating mine.

     CASH PRODUCTION COSTS PER OUNCE - Calculated based upon total cash
     production costs, as defined herein, net of by-product revenues earned
     from all metals other than the primary metal produced at each mine,
     divided by the total ounces of the primary metal produced.

     DECLINE -- An underground passageway connecting one or more levels in a
     mine, providing adequate traction for heavy, self- propelled equipment.
     Such underground openings are often driven in an upward or downward
     spiral, much the same as a spiral staircase.

     DEVELOPMENT -- Work carried out for the purpose of opening up a mineral
     deposit and making the actual ore extraction possible.

     DORE -- Unparted gold and silver poured into molds when molten to form
     buttons or bars.  Further refining is necessary to separate the gold and
     silver.

     EXPLORATION -- Work involved in searching for ore, usually by drilling or
     driving a drift.

     FELDSPARS -- Aluminosilicates that contain potassium, sodium and calcium.
     Feldspar products are primarily used in the ceramic whiteware, glass and
     paint industries.

     FULL PRODUCTION COSTS -- Includes all cash production costs, as defined,
     plus depreciation, depletion and amortization relating to each operating
     mine.





                                      -27-
<PAGE>   29
     FULL PRODUCTION COSTS PER OUNCE - Calculated based upon total full
     production costs, as defined, divided by the total ounces of the primary
     metal produced.

     GRADE -- The average assay of a ton of ore, reflecting metal content.

     HEAP LEACHING -- A process involving the percolation of a cyanide solution
     through crushed ore heaped on an impervious pad or base to dissolve
     minerals or metals out of the ore.

     KAOLIN -- A fine, white clay used as a filler or extender in ceramics and
     refractories.

     MILL -- A processing plant that produces a concentrate of the valuable
     minerals or metals contained in an ore.  The concentrate must then be
     treated in some other type of plant, such as a smelter, to affect recovery
     of the pure metal.

     MINERAL-BEARING MATERIAL -- Material for which quantitative estimates are
     based on inferences from known mineralization, or on drill-hole samples
     too few in number to allow for classification as probable reserves.

     ORE -- Material that can be mined and processed at a positive cash flow.

     PATENTED MINING CLAIM -- A parcel of land originally located on federal
     lands as an unpatented mining claim under the General Mining Law, the
     title of which has been conveyed from the federal government to a private
     party pursuant to the patenting requirements of the General Mining Law.

     PROVEN AND PROBABLE MINERAL RESERVES -- Reserves that reflect estimates of
     the quantities and grades of mineralized material at the Company's mines
     which the Company believes can be recovered and sold at prices in excess
     of the cash cost of production.  The estimates are based largely on
     current costs and on projected prices and demand for the Company's
     products.  Mineral reserves are stated separately for each of the
     Company's mines based upon factors relevant to each mine.  Proven and
     probable mineral reserves for the Greens Creek mine (in which the Company
     owns a 29.7% interest) are based on calculations of reserves provided to
     the Company by the operator of such property that have been reviewed but
     not independently confirmed by the Company.  Greens Creek Mining Company's
     estimates of proven reserves and probable reserves at December 31, 1993
     and 1992 are based on silver prices of $4.75 and $4.50 per ounce, gold
     prices of $350 and $340 per ounce, zinc prices of $0.57 and $0.60 per
     pound, and lead prices of $0.28 and $0.33 per pound, respectively.

     Changes in reserves represent general indicators of the results of efforts
     to develop additional reserves as existing reserves are depleted through
     production.  Grades of ore fed to process may be different from stated
     reserve grades because of variation in grades in areas mined from time to
     time, mining dilution and other factors.  Reserves should not be
     interpreted as assurances of mine life or of the profitability of current
     or future operations.  The Company's estimates of proven reserves and
     probable reserves at December 31, 1993 and 1992 are based on gold prices
     of $375 and $350 per ounce, silver prices of $4.50 and $4.00 per ounce,
     lead





                                      -28-
<PAGE>   30
     prices of $0.23 and $0.30 per pound, and zinc prices of $0.44 and $0.55
     per pound, respectively.

     PROBABLE RESERVES -- Resources for which tonnage and grade and/or quality
     are computed primarily from information similar to that used for proven
     reserves, but the sites for inspection, sampling and measurement are
     farther apart or are otherwise less adequately spaced.  The degree of
     assurance, although lower than that for proven reserves, is high enough to
     assume continuity between points of observation.

     PROVEN RESERVES -- Resources for which tonnage is computed from dimensions
     revealed in outcrops, trenches, workings or drill holes and for which the
     grade and/or quality is computed from the results of detailed sampling.
     The sites for inspection, sampling and measurement are spaced so closely
     and the geologic character is so well defined that size, shape, depth and
     mineral content of reserves are well established.  The computed tonnage
     and grade are judged to be accurate, within limits which are stated, and
     no such limit is judged to be different from the computed tonnage or grade
     by more than 20%.

     RESERVES -- That part of a mineral deposit which could be economically and
     legally extracted or produced at the time of the reserve determination.
     Reserves are customarily stated in terms of "Ore" when dealing with
     metalliferous minerals.

     ROCKBURST -- Explosive rock failures caused by the pressure exerted by
     rock adjacent to mine openings far below the surface.

     SAND FILL -- The coarser fraction of concentrator tailings, which is
     conveyed as a slurry in underground pipes to support cavities left by
     extraction of ore.

     SHAFT -- A vertical or steeply inclined excavation for the purpose of
     opening and servicing a mine.  It is usually equipped with a hoist at the
     top which lowers and raises a conveyance for handling personnel and
     materials.

     STOPE -- An underground excavation from which ore has been extracted
     either above or below mine level.

     TROY OUNCE -- Unit of weight measurement used for all precious metals.
     The familiar 16-ounce avoirdupois pound equals 14.583 Troy Ounces.

     UNDERHAND MINING -- The primary mining method employed in the Lucky Friday
     mine utilizing mechanized equipment, a ramp system and cemented sand fill.
     The method has proven effective in reducing mining cost and rockburst
     activity.

     UNPATENTED MINING CLAIM -- A parcel of property located on federal lands
     pursuant to the General Mining Law and the requirements of the state in
     which the unpatented claim is located, the paramount title of which
     remains with the federal government.  The holder of a valid, unpatented
     lode mining claim is granted certain rights including the right to explore
     and mine such claim under the General Mining Law.





                                      -29-
<PAGE>   31
     VEIN -- A mineralized zone having a more or less regular development in
     length, width and depth which clearly separates it from neighboring rock.

     WASTE -- Barren rock in a mine, or mineralized material that is too low in
     grade to be mined and milled at a profit.

Item 2.     Properties

     The Company's principal mineral properties are described in Item 1 above.
     The Company also has interests in other mineral properties in the United
     States and Mexico.  Although some of such properties are known to contain
     significant quantities of mineralization, they are not considered material
     to the Company's operations at the present time.  Encouraging results from
     further exploration or increases in the market prices of certain metals
     could, in the future, make such properties considerably more important to
     the business of the Company taken as a whole.

     The general corporate office of the Company is located in Coeur d'Alene,
     Idaho, on a tract of land containing approximately 13 acres.  The Company
     also owns and plans to subdivide and sell approximately 70 adjacent acres.

     The administrative offices of the Company's ball clay, kaolin and feldspar
     operations are located five miles southwest of Mayfield, Kentucky.
     Additionally, there are general offices and laboratory facilities at each
     operating location.  The Company also owns approximately 1,600 acres of
     land principally for use in connection with milling and storage
     operations.

     The general offices of the scoria operations are located in Alamosa,
     Colorado.  The Company owns a parcel of land of approximately 20 acres in
     the vicinity of Blanca, Colorado, on which are located building, storage
     and shipping facilities utilized in its scoria business, and a bagging
     plant for landscape scoria.  An additional bagging facility, utilized for
     scoria briquettes, is located at San Acacio, Colorado.

     The general offices of Mountain West Bark Products, Inc. are located in
     Rexburg, Idaho.  Processing facilities are located in both Rexburg, Idaho
     and Superior, Montana.

Item 7.          Management's Discussion and Analysis of Financial Condition
                 and Results of Operations1

INTRODUCTION

The Company is primarily involved in the exploration, development, mining, and
processing of gold, silver, lead, zinc, and industrial minerals.  As such, the
Company's revenues and profitability are strongly influenced by world prices of
gold, silver, lead, and zinc, which fluctuate widely and are affected by
numerous factors beyond the Company's control, including inflation and
worldwide forces of supply and demand.  The aggregate effect of these factors
is not possible to accurately predict.

The Company recorded net losses applicable to common shareholders for each of
the past three years ended December 31, 1993, primarily as a result of:  (1) a
reduction in carrying values of certain mining properties, losses on
investments and provisions for closed operations and environmental matters
totaling $2.7 million in 1993, $42.7 million in 1992 and $3.6 million in 1991;
(2) depressed gold, silver, lead, and zinc prices; and (3) decreased gold
production due to the depletion of oxide ore reserves at the Cactus and Yellow
Pine mines and the decline in ore grade at the Republic mine.

The volatility of metals prices requires that the Company, in assessing the
impact of prices on recoverability of its assets, exercise judgment as to
whether price changes are temporary or are likely to persist (See "Competition
- - Average Metal Prices").  The Company performs a comprehensive evaluation of
the recoverability of its assets on a periodic basis.  The evaluation includes
a review of future cash flows against the carrying value of the asset.  Asset
write-downs may occur if the Company determines that the carrying values
attributed to project assets are not recoverable given reasonable expectations
for future market conditions.

In 1994, the Company expects to produce approximately 106,000 ounces of gold,
including 63,000 ounces from the La Choya gold mine, 38,000 ounces of gold from
the Republic mine and an additional 5,000 ounces of gold from other sources.
Assuming the timely commencement of production at the Grouse Creek gold project
in the fourth quarter of 1994, the Company's planned 1994 total gold production
could increase by up to 53,000 ounces to 159,000 ounces, based upon its 80%
interest in the project.  Assuming the consummation of the planned acquisition
of Equinox Resources Limited (Equinox) in March 1994, the Company's planned
1994 gold production is expected to increase 25,000 ounces to 184,000 ounces,
principally resulting from Equinox's interest in the American Girl mine (See
Note 2 of Notes to Consolidated Financial Statements).  The Company's gold
production increase in 1994 is based upon assuming a full year of production at
the La Choya mine and the start-up of production at the Grouse Creek gold
project in the fourth quarter of 1994, which offsets the expected decrease in
gold production at the Republic mine.  The Company's level of gold production
for 1994 will depend, in part, upon the timely commencement of production at
the Grouse Creek property.

<PAGE>   35
The Company's share of silver production for the year ended December 31, 1993,
was 3.0 million ounces.  Estimated silver production for 1994 is 2.7 million
ounces.  The decrease in estimated silver production in 1994 compared to 1993
is principally due to the suspension of operations at Greens Creek which
commenced in April 1993.

During the year ended December 31, 1993, the Company shipped 888,000 tons of
industrial minerals including ball clay, kaolin, feldspar, and specialty
aggregates.  The Company currently estimates that it will ship 945,000 tons of
industrial minerals during 1994.  Additionally, the Company expects to ship
591,000 cubic yards of landscape material in 1994 from its newly acquired
subsidiary, Mountain West.

The Management's Discussion and Analysis of Financial Condition and Results of
Operations should be read in conjunction with the Company's historical
Consolidated Financial Statements set forth elsewhere herein.

Results of Operations

1993 vs 1992

A net loss of approximately $11.7 million, or $0.36 per common share, was
incurred in 1993 compared to a net loss of $49.3 million, or $1.60 per common
share, in 1992.  After $4.1 million in dividends to holders of the Company's
Series B Cumulative Convertible Preferred Stock (Series B Preferred Stock), the
Company's net loss applicable to common shareholders for 1993 was $15.8
million, or $0.48 per common share.  The 1993 loss was due to a variety of
factors, the most significant of which are discussed below.

Sales of products decreased by $18.8 million, or 19%, in 1993 as compared to
1992, principally the result of (1) decreased gold production due to the
winding down of operations at the Cactus mine, lower-grade ore being mined and
processed at the Republic mine, and the completion of operations at the Yellow
Pine mine during the third quarter of 1992; (2) decreased silver, lead, and
zinc production due to suspension of operations at the Greens Creek mine in
April 1993, and the sale of the Company's 25% interest in the Galena mine in
May 1992; (3) decreases in the average prices of lead and zinc in 1993 compared
to 1992; (4) decreased production of lead at the Lucky Friday mine resulting
from lower lead contained in the ore processed; and (5) decreased sales of ball
clay from Kentucky-Tennessee Clay Company; all of which were partially offset
by (1) increased revenue from the Company's Apex facility; (2) increased sales
of feldspar from K-T Feldspar Corporation, clay slurry products from the
recently completed slurry plant in Monterrey, Mexico, landscape products from
the newly acquired Mountain West, and specialty aggregate products from
Colorado Aggregate Company; and (3) increases in the average prices of gold and
silver in 1993 compared to 1992.

Cost of sales and other direct production costs decreased by $12.2 million, or
15%, in 1993 as compared to 1992, primarily a result of (1) decreased operating
costs at the Greens Creek mine due to suspension of operations in April 1993;
(2) decreased operating costs at the Cactus mine due to the completion of
mining operations in February 1992; (3) decreased operating costs resulting
from the sale of the Company's 25% interest in the Galena mine in May 1992; (4)
decreased operating costs at the Yellow Pine mine resulting from the completion
of operations during the third quarter of 1992; and (5) decreased cost of
production





                                      -34-
<PAGE>   36
at the Republic mine; all of which were partially offset by (1) increased
operating costs during 1993 at the Apex facility, K-T Feldspar Corporation,
Kentucky-Tennessee Clay Company's Ball Clay Division, and Colorado Aggregate
Company; and (2) operating costs in 1993 associated with the newly acquired
Mountain West.

Depreciation, depletion and amortization expense decreased by approximately
$3.2 million, or 24%, in 1993 as compared to 1992, primarily a result of (1)
the suspension of operations at the Greens Creek mine in April 1993, as well as
the completion of mining operations at the Cactus mine in February 1992 and the
Yellow Pine mine during the third quarter of 1992, where depreciable assets
were depreciated primarily on a unit-of-production basis, and (2) significant
assets at Kentucky-Tennessee Clay Company's Ball Clay Division reaching the end
of their depreciable lives.  Both were partially offset by increased
depreciation expense due to increased ore tons mined during 1993 at the Lucky
Friday and Republic mines where significant depreciable assets are depreciated
on a unit-of-production basis.

Other operating expenses decreased by $44.4 million, or 75%, in 1993 as
compared to 1992, primarily the result of (1) the 1992 reduction in carrying
value of mining properties totaling $27.9 million, nonrecurring in 1993,
including (a) a $13.5 million write-down to reflect the estimated net
realizable value of the Company's interest in the Apex facility; (b) a $9.0
million write-down of the Consolidated Silver property in northern Idaho and
the Hog Heaven property in northwest Montana due to depressed silver prices;
(c) a $3.5 million write-down to reflect the estimated net realizable value of
the Company's interest in the Lisbon Valley project in Utah; and (d) a $1.9
million write-down of the Creede and Hardscrabble gold and silver properties
located in Colorado due to depressed precious metals prices; (2) the 1992
provision for closed operations and environmental matters totaling $12.7
million, nonrecurring in 1993, which consisted principally of an $8.5 million
increase in the allowance for the Bunker Hill Superfund Site remediation costs
and additional idle property reclamation and closure costs accruals of $3.3
million as further described in Note 8 of Notes to Consolidated Financial
Statements; (3) decreased domestic exploration expenditures mainly at the
Republic mine in 1993; (4) foreign exploration expenditures in Chile during
1992, nonrecurring in 1993; (5) reduced general and administrative costs in
1993 principally due to staff reductions and other cost-cutting measures at
corporate headquarters; and (6) research expenditures incurred at the Apex
facility during 1992, nonrecurring in 1993.

Other income (expense) netted to income of approximately $1.4 million in 1993
compared to income of $5.5 million in 1992.  The decrease is primarily due to
(1) the sale of surface and timber rights on various nonoperating Company-owned
properties in 1992 resulting in a gain of approximately $9.0 million,
nonrecurring in 1993, and (2) the sale of the Company's 25% interest in the
Galena Unit and adjacent properties in May 1992 resulting in a gain of
approximately $1.2 million, nonrecurring in 1993.  Both of these items were
partially offset by (1) decreased interest expense in 1993 resulting from (a)
the April 29, 1993, issuance of 2.2 million shares of the Company's Common
Stock for 60,400 of its outstanding Liquid Yield Option Notes as described in
Note 7 of Notes to Consolidated Financial Statements, and (b) increased
capitalized interest related to the Grouse Creek and La Choya projects; (2) the
$2.1 million write-down in 1992 of the Company's Common Stock investment in
Granduc Mines Limited to reflect the apparent other- than-temporary decline in
market value of





                                      -35-
<PAGE>   37
the investment, nonrecurring in 1993; and (3) increased interest income earned
in 1993 on the investment of the proceeds from the Company's public offering of
2.3 million shares of Series B Preferred Stock as described in Note 10 of Notes
to Consolidated Financial Statements.

Income taxes reflect a benefit of $0.9 million in 1993 compared to a $0.3
million benefit in 1992.  The benefit in both periods reflects the carryback of
1993 and 1992 net operating losses to reduce income taxes previously provided.

Results of Operations

1992 vs 1991

The net loss for 1992 was $49.3 million, or $1.60 per share, compared to a net
loss of $15.4 million, or $0.51 per share, for 1991.

Sales of products decreased by $16.9 million, or 14%, from 1991 to 1992,
principally as a result of (1) decreased gold production at the Republic and
Cactus mines due to lower-grade ore mined and processed, and the completion of
operations at the Yellow Pine mine in August 1992; (2) decreases in the average
prices of gold, silver, and lead in 1992 compared to 1991; (3) decreased silver
production resulting from the 1992 sale of the Company's 25% interest in the
Galena mine; and (4) decreased silver, zinc, lead and gold production at the
Greens Creek mine due to lower-grade ore mined and processed; all of which were
partially offset by (1) increased silver, lead and zinc production at the Lucky
Friday mine; (2) increased sales of specialty aggregates from Colorado
Aggregate Company during 1992; (3) increases in the average price of zinc; (4)
increased sales of feldspar from K-T Feldspar Corporation during 1992; and (5)
increased sales from the Kaolin Division of Kentucky-Tennessee Clay Company
during 1992.

Cost of sales and other direct production costs decreased $1.6 million, or  2%,
from 1991 to 1992 primarily due to (1) decreased operating costs resulting from
the completion of operations at the Yellow Pine mine in August 1992; (2)
decreased operating costs at the Cactus mine due to the completion of mining
operations in February 1992; (3) decreased operating costs incurred resulting
from the sale of the Company's 25% interest in the Galena mine; and (4)
decreased operating costs at the Republic and Lucky Friday mines; all of which
were partially offset by (1) increased operating costs at the Greens Creek mine
and (2) increased operating costs at Colorado Aggregate Company,
Kentucky-Tennessee Clay Company, and K-T Feldspar Corporation.

Depreciation, depletion and amortization decreased by approximately $7.7
million, or 36%, primarily as a result of the completion of mining operations
at the Cactus mine in February 1992 where depreciation was based on ore tons
mined, and to a lesser extent by (1) the completion of mining operations at the
Yellow Pine mine in August 1992 and (2) the sale of the Company's 25% interest
in the Galena mine; all of which were partially offset by increased ore tons
mined at the Lucky Friday mine where significant depreciable assets are being
depreciated based on ore tons mined.

Other operating expenses increased by $33.3 million, or 130%, due principally
to (1) the reduction in carrying value of mining properties totaling $27.9
million including (a) a $13.5 million write-down to reflect the estimated net
realizable value of the Company's interest in the Apex facility, a
hydrometallurgical





                                      -36-
<PAGE>   38
processing plant near St. George, Utah; (b) a $9.0 million write-down of the
Consolidated Silver property in northern Idaho and the Hog Heaven property in
northwest Montana due to depressed silver prices; (c) a $3.5 million write-down
to reflect the estimated net realizable value of the Company's interest in the
Lisbon Valley project in Utah, a joint venture project fully developed for
uranium and vanadium production; and (d) a $1.9 million write-down of the
Creede and Hardscrabble gold and silver properties located in Colorado due to
depressed precious metals prices; (2) the provision for closed operations and
environmental matters totaling $12.7 million which consisted principally of an
$8.5 million 1992 increase in the allowance for the Bunker Hill Superfund Site
remediation costs and additional idle property reclamation and closure costs
accruals of $3.3 million, as further described in Note 8 of Notes to
Consolidated Financial Statements; and (3) increased exploration expenditures
at the Republic and Lucky Friday mines during 1992; all of which were partially
offset by decreased general and administrative costs principally due to (1)
1991 expenses incurred in connection with the June 26, 1991, merger of CoCa,
nonrecurring in 1992; (2) decreased other general and administrative costs
resulting from closing the CoCa office; and (3) other general and
administrative cost reduction efforts.

Other income (expense) changed from expense of $3.9 million in 1991 to income
of $5.5 million in 1992, primarily a result of (1) the sale of surface and
timber rights on various nonoperating Company-owned properties in 1992
resulting in a gain of approximately $9.0 million; (2) the 1992 sale of the
Company's 25% interest in the Galena mine and adjacent properties located in
northern Idaho, resulting in a gain of about $1.2 million; (3) the exchange of
1,120,125 shares of the Company's Common Stock for 30,900 of the Company's
outstanding Liquid Yield Option Notes resulting in a gain of approximately $0.5
million and a reduction of interest expense in 1992; and (4) increased
capitalized interest related to the Grouse Creek and La Choya projects in 1992;
all of which were partially offset by the $2.1 million write-down of the
Company's Common Stock investment in Granduc Mines Limited to reflect the
apparent other-than-temporary decline in the market value of the investment.

Income taxes reflect a benefit of $0.3 million in 1992 compared to a $2.6
million benefit in 1991.  The benefit in both periods reflects the carryback of
1992 and 1991 net operating losses to reduce income taxes previously provided.

In 1992, the Company changed its method of accounting for income taxes and
postretirement benefits other than pensions.  The adoption of SFAS No. 109,
"Accounting for Income Taxes," resulted in a $1.5 million benefit as of January
1, 1992.  The effect of adopting SFAS No. 106, "Employers' Accounting for
Postretirement Benefits Other Than Pensions," resulted in an additional expense
of $1.6 million as of January 1, 1992.  The net cumulative effect of both of
these accounting changes was to increase the 1992 loss by $0.1 million.

Financial Condition and Liquidity

A substantial portion of the Company's revenue is derived from the sale of
products, the prices of which are affected by numerous factors beyond the
Company's control.  Prices may change dramatically in short periods of time and
such changes have a significant effect on revenues, profits and liquidity of
the Company.  The Company is subject to many of the same inflationary pressures
as the U.S. economy in general.  To date, the Company has been successful in
implementing cost-cutting measures which have reduced per unit production
costs.





                                      -37-
<PAGE>   39
Management believes, however, that the Company may not be able to continue to
offset the impact of inflation over the long term through cost reductions
alone.  However, the market prices for products produced by the Company have a
much greater impact than inflation on the Company's revenues and profitability.
Moreover, the discovery, development and acquisition of mineral properties are,
in many instances, unpredictable events.  Future metals prices, the success of
exploration programs and other property transactions can have a significant
impact on the Company's need for capital.

At December 31, 1993, assets totaled approximately $332.9 million and
shareholders' equity totaled approximately $240.1 million.  Cash, cash
equivalents and short-term investments increased by $62.1 million to $65.4
million at December 31, 1993, from $3.3 million at the end of 1992.  The major
sources of cash and short-term investments were the $110.3 million net proceeds
received from the June 29, 1993, issuance of 2.3 million shares of Series B
Preferred Stock as described further in Note 10 of Notes to Consolidated
Financial Statements and proceeds of approximately $1.1 million from the
issuance of Common Stock under stock option plans.  Other major sources of cash
were from operations at the Republic and Cactus mines, Kentucky-Tennessee Clay
Company's Ball Clay and Kaolin Divisions, K-T Feldspar Corporation, and
Colorado Aggregate Company.  The major uses of cash were for (1) the
development costs incurred in connection with the Grouse Creek and La Choya
projects; (2) property, plant and equipment expenditures at the clay slurry
plant in Mexico, Kentucky-Tennessee Clay Company's Kaolin Division and Colorado
Aggregate Company; (3) general and administrative expenses; (4) exploration
costs; (5) idle property expenditures including environmental costs; and (6)
operations at the Lucky Friday mine, the Apex facility, and Mountain West.

The Company estimates that capital expenditures to be incurred in 1994 will be
approximately $62.2 million.  The estimated capital expenditures for 1994
reflect the sale of a 20% ownership interest in the Company's Grouse Creek
project as described in Note 5 of Notes to Consolidated Financial Statements.
The Company's 1994 capital expenditures are expected to consist primarily of
(1) development expenditures at the Grouse Creek project totaling approximately
$50.0 million; (2) further development expenditures at the Greens Creek mine
totaling approximately $3.4 million; and (3) assuming completion of the
acquisition of Equinox as described below, development expenditures at
Equinox's Rosebud and Oro Cruz projects totaling approximately $3.7 million and
$1.3 million, respectively.  The Company intends to finance these capital
expenditures through a combination of (1) existing cash, cash equivalents and
short-term investments; (2) proceeds from the sale of a minority joint venture
interest in the Grouse Creek project as described in Note 5 of Notes to
Consolidated Financial Statements; and (3) cash flow from operating activities.
In addition, the Company may borrow additional funds under its revolving credit
facility which, subject to certain conditions, provides for borrowings up to a
maximum of $30.0 million, as described further in Note 7 of Notes to
Consolidated Financial Statements.  Moreover, to the extent the Company is able
to complete a securities offering, as described below, excess proceeds, if any,
may be used for these capital expenditures.

As further described in Note 2 of Notes to Consolidated Financial Statements,
the Company has entered into an Acquisition Agreement to acquire Equinox.  The
Company's 1994 expenditures on the Rosebud and Oro Cruz projects are contingent
upon the Company's successful consummation of the acquisition of Equinox.





                                      -38-
<PAGE>   40
The Company's planned environmental and reclamation expenditures for 1994 are
expected to be approximately $6.6 million, principally for environmental and
reclamation activities at the Bunker Hill and California Gulch Superfund Sites
and at the Yellow Pine, Escalante and Durita properties.

Exploration expenditures for 1994 are estimated to be approximately $6.2
million.  The Company's exploration strategy is to focus further exploration at
or in the vicinity of its currently owned properties.  Accordingly, 1994
exploration expenditures will be incurred principally at the Republic, Grouse
Creek and La Choya properties.

As described in Note 7 of Notes to Consolidated Financial Statements, the
Company has a secured reducing revolving credit facility which provides for
credit advances of up to $30.0 million.  The availability of advances under
this facility reduces commencing December 31, 1995, and is subject to certain
other limitations, with the balance due at maturity on December 31, 1996.
Borrowings under the facility are secured by the accounts receivable,
inventories, and specified marketable securities.  As of December 31, 1993, the
Company had no outstanding borrowings under the revolving credit facility.

As further described in Note 7 of Notes to Consolidated Financial Statements,
on April 23, 1993, the Company exchanged 2.2 million shares of its common stock
for 60,400 outstanding Liquid Yield Option Notes in a noncash transaction.

The Company currently has outstanding $109,950,000 aggregate principal amount
of Liquid Yield Option Notes (LYONs) due 2004, which are currently convertible
into 20.824 shares of common stock per $1,000 principal amount of LYONs.
Pursuant to the terms of the indenture governing the LYONs, on June 14, 1994,
holders of LYONs may require the Company to purchase LYONs held by them (the
Put Feature) at a purchase price of $456.39 per $1,000 principal amount of
LYONs.  The purchase price may be paid, at the option of the Company, in cash,
in shares of common stock (valued at the market price of the common stock) or
in the Company's Subordinated Extension Notes due 2004; but because of the
Company's need to utilize cash for planned capital expenditures, it is probable
that, absent any action by the Company, it will pay for any LYONs delivered to
it pursuant to the Put Feature by issuing common stock.  The Company is unable
to predict how many LYONs it may be required to purchase pursuant to the Put
Feature, and the Company cannot predict what effect the Put Feature will have
on the market price of its common stock.

The Company is currently considering several alternatives with respect to the
Put Feature.  One of the alternatives being examined by the Company is the sale
of additional shares of common stock (or other Company securities) with the
proceeds of such an offering being used to pay cash for LYONs delivered to the
Company pursuant to the Put Feature (and any remaining proceeds would be used
for capital expenditures).  The Company is also considering amending certain
terms of the LYONs in order to make it less likely that the Put Feature will be
exercised on June 14, 1994, including changing the conversion ratio to increase
the number of shares of common stock that would be issuable for each LYON.  If
either of these alternatives is pursued, then additional shares of common stock
could be issued, although the Company's intent with respect to these
alternatives is to issue less shares of common stock (other than any securities
sold to raise additional funds for capital expenditures) than would be the case
if the Company was required to repurchase all of the outstanding LYONs pursuant
to the Put Feature on June 14,





                                      -39-
<PAGE>   41
1994.  If the Company takes no action with respect to the Put Feature and is
required to purchase all of the outstanding LYONs on June 14, 1994, based upon
year end market prices ($11.63 on December 31, 1993), the Company would have to
issue approximately 4,300,000 shares of common stock.  There can be no
assurance that the Company will determine to pursue, or be successful in
pursuing, any alternative (including and in addition to the alternatives
discussed above) to reduce the likelihood that the Put Feature will result in
the issuance of a significant amount of the Company's common stock.

In December 1993, the Company acquired all of the issued and outstanding common
stock of Mountain West through the issuance of 655,000 shares of the Company's
common stock with an estimated value of $6,305,000.  Mountain West is engaged
primarily in the mining and processing of scoria, specialty aggregates and
landscaping products.  The transaction has been accounted for as a purchase.

As further described in Note 8 of Notes to Consolidated Financial Statements,
the Company has been notified by the United States Environmental Protection
Agency (EPA) that it has been designated by the EPA as a potentially
responsible party with respect to several Superfund sites.  At December 31,
1993, the Company's allowance for Superfund site remedial action costs was
approximately $10.7 million, which the Company believes is adequate based on
current estimates of aggregate costs.  Although the ultimate disposition of
these and various other pending legal actions and claims is not presently
determinable, it is the opinion of the Company's management, based upon the
information available at this time, that the outcome of these suits and
proceedings will not have a material adverse effect on the consolidated results
of operations and financial condition of the Company.

Other

In November 1992, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 112, "Employers' Accounting for
Postemployment Benefits" (SFAS No. 112).  This statement requires companies to
recognize the obligation to provide postemployment benefits if the obligation
is attributable to employees' services already rendered, employees' rights to
those benefits have accumulated or vested, payment of the benefits is probable
and the amount of the benefits can be reasonably estimated.  The statement
requires the Company to make the necessary changes in accounting for these
postemployment benefits effective January 1, 1994.  It is the opinion of the
Company's management that the adoption of SFAS No. 112 will not have a material
effect on the consolidated results of operations or financial condition of the
Company.

                      REPORT OF INDEPENDENT ACCOUNTANTS



The Board of Directors and Shareholders 
Hecla Mining Company


We have audited the accompanying consolidated balance sheets of Hecla Mining 
Company and subsidiaries as of December 31, 1993 and 1992, and the related 
consolidated statements of operations, changes in shareholders' equity and 
cash flows for each of the three years in the period ended December 31, 1993.  
These financial statements are the responsibility of the Company's 
management.  Our responsibility is to express an opinion on these financial 
statements based on our audits.

We conducted our audits 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 provide a 
reasonable basis for our opinion.

In our opinion, the financial statements referred to above present fairly, 
in all material respects, the consolidated financial position of Hecla 
Mining Company and subsidiaries as of December 31, 1993 and 1992, and the 
consolidated results of their operations and their cash flows for each of 
the three years in the period ended December 31, 1993 in conformity with 
generally accepted accounting principles.

As discussed in Notes 6 and 9 to the consolidated financial statements, the 
Company changed its method of accounting for income taxes and postretirement 
benefits other than pensions in 1992.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS



Note l:   Summary of Significant Accounting Policies

          A.  COMPANY'S BUSINESS AND CONCENTRATIONS OF CREDIT RISK - Hecla
     Mining Company and its subsidiaries (the Company) are engaged in mining
     and mineral processing.  Sales of metals products are made principally to
     domestic and foreign custom smelters and metal traders.  Industrial
     minerals are sold principally to domestic manufacturers and wholesalers.
     Sales to significant metals customers, as a percentage of total sales of
     metals products, were as follows:

</TABLE>


          During 1993, 1992 and 1991, the Company sold 19%, 26%, and 17% of its
     products to companies in foreign countries, respectively.

          The Company's financial instruments that are exposed to
     concentrations of credit risk consist primarily of cash and cash
     equivalents and trade accounts receivable.  The Company places its cash
     and temporary cash investments with high credit worthy institutions.  At
     times such investments may be in excess of the FDIC insurance limit.  The
     Company routinely assesses the financial strength of its customers and, as
     a consequence, believes that its trade accounts receivable credit risk
     exposure is limited.

          B.  BASIS OF CONSOLIDATION - The consolidated financial statements
     include the accounts of the Company, its majority-owned subsidiaries and
     its proportionate share of the accounts of the joint ventures in which it
     participates.  All significant intercompany transactions and accounts are
     eliminated.

          C.  INVENTORIES - Inventories are stated at the lower of average cost
     or estimated net realizable value.

          D.  INVESTMENTS - The Company follows the equity method of accounting
     for investments in common stock of operating companies 20% to 50% owned.
     Investments in nonoperating companies that are not intended for resale or
     are not readily marketable are valued at the lower of cost or net
     realizable value.  The carrying value of marketable equity securities is
     based on the lower of aggregate cost or quoted market value.  The cost of
     investments sold is determined by specific identification.





                                      F-7
<PAGE>   53
          Short-term investments represent investments in certificates of
     deposits, commercial paper and U.S. Treasury Notes recorded at amortized
     cost, plus accrued interest, which approximates market value.

          E.  PROPERTIES, PLANTS AND EQUIPMENT - Properties, plants and
     equipment are stated at the lower of cost or estimated net realizable
     value.  Maintenance, repairs and renewals are charged to operations.
     Betterments of a major nature are capitalized.  When assets are retired or
     sold, the costs and related allowances for depreciation and amortization
     are eliminated from the accounts and any resulting gain or loss is
     reflected in operations.  Idle facilities, placed on a standby basis, are
     carried at the lower of net book value or estimated net realizable value.

          Management of the Company reviews the net carrying value of all
     facilities, including idle facilities, on a regular, periodic basis.
     These reviews consider, among other factors, (1) the net realizable value
     of each major type of asset, on a property-by-property basis, to reach a
     judgment concerning possible permanent impairment of value and any need
     for a write-down in asset value, (2) the ability of the Company to fund
     all care, maintenance and standby costs, (3) the status and usage of the
     assets, while in a standby mode, to thereby determine whether some form of
     amortization is appropriate, and (4) current projections of metal prices
     that affect the decision to reopen or make a disposition of the assets.

          Depreciation is based on the estimated useful lives of the assets and
     is computed using straight-line, declining-balance, and unit-of-production
     methods.  Depletion is computed using the unit-of-production method.

          F.  MINE EXPLORATION AND DEVELOPMENT - Exploration costs are charged
     to operations as incurred, as are normal development costs at operating
     mines.  Major mine development expenditures at operating properties and at
     new mining properties not yet producing are capitalized.

          G.  RECLAMATION OF MINING AREAS - Minimum standards for mine
     reclama-tion have been established by various governmental agencies which
     affect certain operations of the Company.  A reserve for mine reclamation
     costs has been established for restoring certain abandoned and currently
     disturbed mining areas based upon estimates of cost to comply with
     existing reclamation standards.  Mine reclamation costs for operating
     properties are accrued using the unit-of-production method.

          H.  INCOME TAXES - In the fourth quarter of 1992, the Company adopted
     the provisions of Statement of Financial Accounting Standards No. 109,
     "Accounting for Income Taxes" (SFAS No. 109), retroactive to January 1,
     1992.  SFAS No. 109 requires a company to recognize deferred tax
     liabilities and assets for the expected future income tax consequences of
     events that have been recognized in a company's financial statements.
     Under this method, deferred tax liabilities and assets are determined
     based on the temporary differences between the financial statement
     carrying amounts and tax bases of assets and liabilities using enacted tax
     rates in effect in the years in which the temporary differences are
     expected to reverse.  In 1991, the Company utilized the liability method
     of accounting for income taxes as required by Statement of Financial
     Accounting Standards No. 96.

          I.  NET LOSS PER COMMON SHARE - Net loss per common share is computed
     by adding preferred stock dividends to net loss and dividing the result by
     the weighted average number of shares of common stock and common stock





                                      F-8
<PAGE>   54
     equivalents (stock options) outstanding during each reporting period
     unless the common stock equivalents are anti-dilutive.  Due to the net
     losses in 1993, 1992 and 1991, common stock equivalents are anti-dilutive
     and therefore have been excluded from the computation.

          J.  REVENUE RECOGNITION - Sales of metal products sold directly to
     smelters are recorded when they are received by the smelter, at estimated
     metal prices.  Recorded values are adjusted periodically and upon final
     settlement.  Metal in products tolled (rather than sold to smelters) is
     sold under contracts for future delivery; such sales are recorded at
     contractual amounts when products are available to be processed by the
     smelter or refinery.  Sales of industrial minerals are recognized as the
     minerals are delivered.

          K.  INTEREST EXPENSE - Interest costs incurred during the
     construction of qualifying assets are capitalized as part of the asset
     cost.

          L.  CASH EQUIVALENTS - The Company considers cash equivalents to
     consist of highly liquid investments with a remaining maturity of three
     months or less when purchased.  For investments characterized as cash
     equivalents, the carrying value is a reasonable estimate of fair value.

          M.  FOREIGN CURRENCY TRANSLATION - All assets and liabilities of the
     Company's Canadian and Mexican operations are translated to U. S. dollars
     using the exchange rate at the balance sheet date.  Income and expense
     items are translated using average exchange rates.  Gains and losses from
     foreign currency transactions are included in operations.

Note 2:   Business Combinations

     Equinox Resources Limited

          On December 29, 1993, the Company, two wholly owned Canadian
     subsidiaries of the Company, and Equinox Resources Ltd.  (Equinox), a
     mining, exploration and development company, incorporated under the laws
     of the Province of British Columbia and headquartered in Vancouver,
     Canada, executed an Acquisition Agreement providing for the Company's
     acquisition of Equinox.  Pursuant to the Acquisition Agreement and related
     Plan of Arrangement, upon consummation of the transactions contemplated
     thereby, (i) Equinox common shareholders will receive 0.3 common share of
     the Company (Company common shares), for each outstanding Equinox common
     share, (ii) holders of Equinox's Series "A" production participating
     preferred shares will receive newly issued production notes of the Company
     with the same material terms and conditions, and (iii) outstanding Equinox
     options and warrants will become exercisable for Company common shares.
     In connection with the acquisition of Equinox, the Company expects to
     issue approximately 6.3 million Company common shares, including shares
     issuable upon exercise of outstanding options and warrants.

          The Board of Directors of the Company and Equinox have each approved
     the Acquisition Agreement.  However, the transactions contemplated by the
     Acquisition Agreement are subject to a number of conditions including,
     without limitation, approval by Equinox shareholders, and approval by a
     Canadian court of the Plan of Arrangement.

          Assuming the transaction is consummated as planned, the acquisition
     will be treated as a pooling-of-interests, and accordingly, the

     consolidated financial statements will be restated to reflect the accounts
     of Equinox.

          Pro forma unaudited results of operations assuming the merger had

     Mountain West Bark Products, Inc.

           In December 1993, the Company acquired all of the issued and
     outstanding common stock of Mountain West Bark Products, Inc. (Mountain
     West) through the issuance of 655,000 shares of the Company's common
     stock.  Mountain West is engaged primarily in the purchasing, processing
     and marketing of certain waste products from lumber milling operations in
     the western intermountain region.  These products are sold as soil
     amendments, landscape mulches and decorative ground cover for landscape
     purposes.  The transaction has been accounted for as a purchase and,
     accordingly, the acquired assets and liabilities have been recorded at
     their estimated fair value at December 1, 1993, the date of the
     acquisition.  Mountain West's operating results have been included in the
     consolidated financial statements since that date and were immaterial to
     the Company.  Results of operations of Mountain West prior to December 1,
     1993, were not material and, therefore, are not presented.  The value of
     the Company's common shares issued in this transaction was approximately
     $6,305,000.  Goodwill of $1,733,000 was recorded in the transaction and is
     being amortized straight-line over 15 years.

          At December 31, 1993, the Company had forward sales commitments for
     4,500 ounces of gold at an average price of $363 per ounce.  The
     commitments are for delivery in February 1994.  There is no silver
     committed to forward sales at December 31, 1993.  The Company purchased
     options to put 41,880 ounces of gold to the counterparties at an average
     price of $385 per ounce.  Concurrently, the Company sold options to allow
     the counterparties to call 41,880 ounces of gold from the Company at an
     average price of $453 per ounce.  There was no net cost associated with
     the purchase and sale of these options.

           At December 31, 1993, the portfolio of noncurrent marketable equity
      securities includes gross unrealized gains of approximately $9,000 and
      gross unrealized losses of approximately $17,000.  The other investments
      are principally large blocks of common and preferred stock in several
      mining companies, investments in various ventures, and cash surrender
      value of life insurance policies.  The securities are generally
      restricted as to trading or marketability, although some are traded on
      various exchanges.

           At December 31, 1993, other investments with a carrying value of
      $5,430,632 had an estimated fair value of $7,689,811 based on the quoted
      market price for such securities and cash values of life insurance
      policies.  For the remaining other investments, for which there are no
      reliable quoted market prices, a reasonable estimate of fair value could
      not be made without incurring excessive costs.

           During the fourth quarter of 1992, the Company wrote down its common
      stock investment in Granduc Mines Limited (Granduc) to current estimated
      market value.  The $2.1 million write-down of this investment was
      recorded to reflect the apparent other- than-temporary decline in market
      value of the common stock investment due to continued depressed metal
      prices.  At December 31, 1993, the Company's carrying value of its
      Granduc common stock investment was approximately $1,488,000.

           On January 24, 1994, the Company sold its entire investment in
      Granduc by selling 2,000,000 Granduc common shares to Conwest Exploration
      Company Limited and 815,330 Granduc common shares to Jascan Resources
      Inc., both of which are Toronto, Ontario, Canada based companies.  The
      Company recognized a gain on the sale of approximately $1,327,000 in the
      first quarter of 1994.

           On June 30, 1993, the Company sold substantially all of its interest
      in Acadia Mineral Ventures Limited, a previously consolidated subsidiary,
      to Kingswood Resources, Inc., a Canadian exploration and development
      company, for (C)$350,000 cash, plus 5,000,000 Kingswood Resources, Inc.
      common shares.  The Company recognized a loss on the sale of
      approximately $120,000 in the second quarter of 1993.

           Based on its periodic reviews of the status of various mining
      properties and investments, the Company determined in the fourth quarter
      of 1992 that certain adjustments were appropriate to properly reflect
      estimated net realizable values.  These adjustments consisted primarily
      of the write-downs of various properties, plants and equipment totaling
      approximately $28.0 million.  The major portion of the adjustments
      related to the $13.5 million write-down of the Company's interest in the
      Apex Unit, a hydrometallurgical processing plant near St. George, Utah.
      The Company continues to evaluate the feasibility of custom recoveries of
      specialty metals and chemical products.  Also in 1992, due to depressed
      silver prices, the Company recorded write-downs of approximately $9.0
      million related to the Consolidated Silver and Hog Heaven silver
      properties, located in North Idaho and northwest Montana, respectively.
      The Lisbon Valley Project in Utah, a joint venture which is fully
      developed for uranium and vanadium production, was also written down in
      1992 by approximately $3.5 million to its estimated net realizable value.
      Included in the 1992 write-downs were approximately $1.5 million and $0.4
      million

      related to the Company's interests in the Creede and Hardscrabble gold
      and silver properties, respectively, both located in Colorado.

           On May 19, 1992, the Company acquired interests in a number of
      Mexican mineral concessions for approximately $2.9 million.  The purchase
      consideration included the issuance of 184,862 shares of the Company's
      common stock valued at $1.8 million.

           The net carrying values of the major mining properties of the
      Company that were on a standby or idle basis at December 31, 1993 and
      1992 were approximately $55.3 million and $5.3 million, respectively.
      Operations at the Greens Creek mine, with a net carrying value of $49.2
      million at December 31, 1993, were suspended in April 1993 pending
      improvement in lead, zinc and silver prices.

           On February 8, 1994, the Company sold a 20 percent interest in its
      Grouse Creek gold project to Great Lakes Minerals Inc.  of Toronto,
      Ontario.  The purchase price of $6.8 million represents 20 percent of the
      amount spent by the Company on acquisition, exploration and development
      of the project through June 30, 1993, including a fixed premium of $1.25
      million.  In addition, Great Lakes will fund its pro-rata share of the
      total construction cost for Grouse Creek from July 1, 1993 to the
      completion of the project which is currently estimated at $90.0 million,
      and has the option to increase its ownership to a maximum of 30 percent
      by contributing additional funds on a proportional basis.

           Effective January 1, 1992, the Company adopted the provisions of
      SFAS No. 109.  As of January 1, 1992, the Company recorded a tax benefit
      of approximately $1.5 million ($0.049 per common share), which represents
      the net decrease in the deferred tax liability as of that date.  This has
      been reflected in the consolidated statement of operations as a component
      of the cumulative effect of changes in accounting principles.

           In 1992 and 1991, for income tax purposes, the Company carried back
      current operating losses to offset income recorded in prior years and
      recorded income tax refunds of approximately $390,000 and $2.2 million,
      respectively.

           In addition to the above, the Company had Mexican tax net operating
      loss carryovers totaling $1,280,000, which expire in 1998.

           During 1992, the Company used prior year capital loss carryovers of
      approximately $7.4 million to offset 1992 capital gains.  At December 31,
      1993, for income tax purposes, the Company had approximately $6.0 million
      of alternative minimum tax net operating losses generated by CoCa Mines
      Inc. prior to its merger with the Company in 1991.  Due to the merger,

      Zero Coupon Convertible Notes

           During 1989, the Company issued subordinated zero coupon convertible
      notes, due June 14, 2004, with a face value at maturity of $201,250,000.
      These Liquid Yield Option Notes (LYONs) were issued at 30.832% of their
      face value at maturity which results in an 8% yield compounded
      semiannually to maturity.  These notes are carried net of original issue
      discount, which is being amortized by the interest method over the life
      of the issue.  The outstanding balances at December 31, 1993 and 1992,
      include the accrued original issue discount.  The noteholder, at his
      option, may convert each note with a face value of $1,000 into 20.824
      shares of the Company's common stock.  The notes are redeemable in cash
      at any time at the option of the Company, in whole or in part, at
      redemption prices equal to the issue price plus original issue discount
      to the date of redemption.  The Company will purchase any note with a
      face value of $1,000 at the option of the holder on June 14, 1994 (Put
      Feature), at a purchase price of $456.39 (issue price plus original issue
      discount to such date).  The Company, at its option, may pay such
      purchase price in cash, shares of common stock or extension notes, but
      not in any combination thereof.  However, because of the Company's need
      to utilize cash for planned capital expenditures, absent any action by
      the Company, it will pay for any LYONs delivered to it pursuant to the
      Put Feature by issuing Company common stock.  The Company is unable to
      predict how many LYONs it may be required to purchase pursuant to the Put
      Feature and cannot predict what effect the Put Feature will have on the
      market price of Company common stock.

           The Company is currently considering several alternatives with
      respect to the Put Feature.  Among the alternatives being examined by the
      Company is the sale of additional shares of the Company's common stock
      (or other Company securities) with the proceeds of such an offering being
      used to pay cash for LYONs delivered to the Company pursuant to the Put
      Feature (and any remaining proceeds would be used for the Company's
      capital expenditures).  The Company is also considering amending certain
      terms of the LYONs in order to make it less likely that the Put Feature
      will be exercised on June 14, 1994, including changing the conversion
      ratio to increase the number of shares of the Company's common stock that
      would be issuable for each LYON.  If either of these alternatives is
      pursued, then additional shares of Company common stock could be issued,
      although the Company's intent with respect to these alternatives is to
      issue less shares of Company common stock (other than any securities sold
      to raise additional funds for capital expenditures) than would be the
      case if the Company was





                                      F-18
<PAGE>   64
      required to repurchase all of the outstanding LYONs pursuant to the Put
      Feature on June 14, 1994.  However, if the Company takes no action with
      respect to the Put Feature and is required to purchase all of the
      outstanding LYONs on June 14, 1994, based upon year end market prices
      ($11.63 on December 31, 1993), the Company would have to issue
      approximately 4,300,000 shares of Company common stock.  There can be no
      assurance that the Company will determine to pursue, or be successful in
      pursuing, any alternative (including and in addition to the alternatives
      discussed above) to reduce the likelihood that the Put Feature will
      result in the issuance of a significant amount of the Company's common
      stock.

           At December 31, 1993, remaining deferred debt issuance costs of
      approximately $1.4 million incurred in connection with the issuance of
      this debt is being amortized using the interest method over the life of
      the issue.

           On May 19, 1992, the Company exchanged 1,120,125 shares of its
      common stock for 30,900 outstanding LYONs.  In the noncash transaction,
      the Company recorded the issuance of common stock totaling approximately
      $11.2 million and the reduction of long- term debt and deferred issuance
      costs totaling approximately $12.0 million and $0.3 million,
      respectively, recognizing a gain totaling approximately $0.5 million.

           On April 29, 1993, the Company exchanged 2.2 million shares of its
      common stock for 60,400 outstanding LYONs.  The Company recorded the
      issuance of common stock totaling approximately $24.4 million and the
      reduction of long-term debt and deferred issuance costs totaling
      approximately $25.2 million and $0.5 million, respectively, recognizing a
      gain from this transaction of approximately $0.3 million.  The market
      value of the outstanding LYONs at December 31, 1993, is $48.4 million
      based on quoted market prices for the debt.

      Notes Payable

           The notes are noninterest-bearing, discounted at 15% and payable in
      three annual equal amounts from the date of commercial production of the
      Grouse Creek property which is currently estimated to be October 1994.
      The fair value of these notes payable approximates the carrying value at
      December 31, 1993.

      Revolving Credit Agreement

           On January 25, 1993, the Company entered into a secured reducing
      revolving credit facility.  The agreement provided for reducing revolving
      credit advances of up to $24.0 million.  On November 11, 1993, the
      Company amended this agreement to provide for reducing revolving credit
      advances of up to $30.0 million.  There were no outstanding borrowings
      under this agreement at December 31, 1993.  Pursuant to the amended
      agreement, the availability under the facility reduces as follows:

           Commitment fees are 1/2 of 1 percent on the average daily unused
      portion of the base commitment.  The interest rate options are a
      specified bank's reference rate plus 1/2 percent, a CD Rate plus 1 5/8
      percent or the Offshore Rate plus 1 1/2 percent.  No compensating
      balances are required.  Borrowings under the agreement are collateralized
      by the Company's accounts receivable, inventories, and specified
      marketable securities.  The agreement contains restrictive covenants,
      among others, concerning the maintenance of a minimum net worth, current
      ratio, leverage ratio, and fixed charge coverage ratio.

Note 8:    Contingencies

           The Company has received notices from the United States
      Environmental Protection Agency (EPA) that it and numerous other parties
      are potentially responsible to remediate alleged hazardous substance
      releases at several sites under the Comprehensive Environmental Response
      Compensation and Liability Act of 1980 (CERCLA or Superfund).  In
      addition, in January of 1985, the Company was named, along with a number
      of other parties, as a third-party defendant in a suit initially brought
      by the State of Colorado against ASARCO Inc. in December 1983 in Colorado
      Federal District Court under CERCLA to recover natural resource damages
      allegedly caused by releases of hazardous substances into the environment
      from the Yak Tunnel, located near Leadville, Colorado (Leadville Site).
      The third-party complaint seeks contribution from the third-party
      defendants for damages which ASARCO may be held liable for in the primary
      action.  In August 1986, the Company was named a defendant in a lawsuit
      brought in Colorado Federal District Court by the United States of
      America against the Company and a number of other parties seeking to
      recover the United States' response costs under CERCLA incurred or to be
      incurred at the Leadville Site covered by the State of Colorado lawsuit
      filed previously.  The state and federal government CERCLA litigation
      related to the Leadville Site was consolidated into a single lawsuit on
      February 2, 1987.  In September 1991, the Company entered into an Order
      on Consent with the EPA and the Department of Justice pursuant to which
      the Company and the federal government agreed to a three-step process for
      settling the Company's liability to the federal government at the
      Leadville Site.  As a step in the three-step settlement process, on
      January 6, 1993, the Colorado Federal District Court entered a Partial
      Consent Decree between the United States and the Company which resolves
      all issues concerning the Company's alleged liability to the United
      States for response costs at the site, except for response costs related
      to certain mill tailings impoundments located at the Leadville Site.  The
      Company paid the United States $450,000 under the decree.  The other two
      steps in the settlement process at the site relate to the Company
      finalizing a study of any environmental impacts associated with the
      tailings impoundments and implementing the appropriate response activity
      to address these impacts.  In July 1993, the Company completed and
      delivered to EPA the study report analyzing the environmental impacts
      associated with the tailings impoundments.  Based on that study report,
      EPA has selected a response action for the tailings impoundments which
      requires capping and providing of vegetation cover for the tailings
      impoundments.  The Company has recently finalized the terms of a consent
      decree with the federal government providing for the payment by the
      Company of $516,000 to cover a portion of EPA's past costs at the site
      and a portion of the costs of the selected response action for the
      tailings impoundments.  The consent decree is in the process of being
      signed by all parties and must also be approved by the Colorado Federal
      District Court.  Upon final approval of the consent decree, the Company
      will be released from liability for response costs for





                                      F-20
<PAGE>   66
      the entire Leadville Site.  In November 1991, the Company finalized a
      settlement with two primary liability insurers concerning insurance
      coverage for the Company's environmental liability at the Leadville Site.
      The monies received in the insurance settlement in November 1991 are
      sufficient to cover the Company's CERCLA liability at the site.

           In October 1989, and again in February 1990, the Company was
      notified by the EPA that the EPA considered the Company a Potentially
      Responsible Party (PRP) at the Bunker Hill Superfund Site located at
      Kellogg, Idaho (Bunker Hill Site).  The EPA has also notified a number of
      other companies involved in mining or smelting activities in the site
      area that the EPA has determined they are also PRPs at the site.  The EPA
      has asserted that all PRPs, including the Company, are responsible for
      the EPA's response costs and for remediating the Bunker Hill Site as a
      result of the parties' release of hazardous substances at or into the
      site.  In August 1991, the EPA issued a Record of Decision regarding the
      remedial action plan for the populated areas of the site.  During the
      summers of 1990, 1991, 1992, and 1993, the Company participated, along
      with a number of other PRPs at the site, in a number of Orders on Consent
      pursuant to which the participating PRPs agreed to undertake certain
      limited remedial activities related to the populated areas of the site.
      The Company has also participated with Gulf USA Corporation, one of the
      PRPs at the site, in an Order on Consent with the EPA pursuant to which
      the Company and Gulf USA agreed to undertake certain remedial activity
      with regard to the hillsides located within the site.  The EPA's Record
      of Decision covering the nonpopulated areas of the site was issued on
      September 22, 1992.  On November 4, 1992, the EPA issued special notice
      letters under CERCLA to the Company and a number of other PRPs at the
      site demanding reimbursement of the federal government's past response
      costs and implementation of the remedial activity covered by the two
      previous Records of Decision issued for the site.  In November 1992, the
      major PRPs at the site, including the Company, agreed to an allocation of
      most of the future remedial activity at the site under the Records of
      Decision.  The allocation is between two PRP groups.  One PRP group is
      principally made up of mining companies who operated upstream from the
      site, and the second PRP group is made up of Gulf USA and other companies
      who had mining, smelting, or related operations within the site.  The
      allocation for remedial activity among the two PRP groups is based upon a
      number of factors, including each PRP's level of activity affecting the
      site and an estimate of the costs to implement the various portions of
      the site remediation.  On January 11, 1993, the Company and certain other
      PRPs who had received the special notice letters submitted to the EPA an
      offer which the PRPs deemed should satisfy the government's requirements
      under CERCLA for a good-faith offer.  Under the terms of the offer, the
      Company and a subset of the participating PRPs would assume
      responsibility for most residential and commercial soils remediation and
      other incidental and related activities.  A different PRP sub-group, of
      which the Company is not a member but which includes Gulf USA, would be
      responsible for implementing most of the remaining site's remedial
      activities.  The responsibility of each PRP group would be several from
      the responsibilities of the other group, but would be joint and several
      among the PRPs within each group.  The Company estimates most of the
      proposed remedial activity at the site will be undertaken over a period
      of five to seven years.  The PRPs' good-





                                      F-21
<PAGE>   67
      faith offer did not include payment of any of the government's past
      response costs.  In October 1993, Gulf USA filed voluntary bankruptcy
      under Chapter 11 of the United States Bankruptcy Code.  Notwithstanding
      Gulf's bankruptcy filing, the PRP group including the Company has
      recently finalized the terms of a consent decree with the federal
      government generally along the allocation of liability set forth in the
      PRP's good-faith offer.  The Company and the other PRPs participating in
      the consent decree have also agreed to an allocation of costs to
      implement the work at the Bunker Hill Site under the terms of the consent
      decree.  The consent decree at the Bunker Hill Site is in the process of
      being executed by all parties and will also be subject to Idaho Federal
      District Court approval.

           In July 1991, the Coeur d'Alene Indian Tribe brought a lawsuit,
      under CERCLA, in Idaho Federal District Court against the Company and a
      number of other mining companies asserting claims for damages to natural
      resources located downstream from the Bunker Hill Site over which the
      Tribe alleges some ownership or control.  The Company has answered the
      Tribe's complaint denying liability for natural resource damages and
      asserted a number of defenses to the Tribe's claims, including a defense
      that the Tribe has no ownership or control over the natural resources
      they assert have been damaged.  In July 1992, the Idaho Federal District
      Court, in a separate action, determined that the Coeur d'Alene Indian
      Tribe does not own the beds, banks and waters of Lake Coeur d'Alene and
      the lower portion of its tributaries, the ownership of which is the
      primary basis for the natural resource damage claims asserted by the
      Coeur d'Alene Indian Tribe against the Company.  Based upon the Tribe's
      appeal of the July 1992 district court ownership decision to the 9th
      Circuit U.S. Court of Appeals, the court in the natural resource damage
      litigation issued an order on October 30, 1992, staying the court
      proceedings in the natural resource damage litigation until a final
      decision is handed down on the question of the Tribe's title.

           In 1991, the Company initiated litigation in the Idaho State
      District Court in Kootenai County, Idaho, against a number of insurance
      carriers which provided comprehensive general liability insurance
      coverage to the Company and its predecessors.  The Company believes that
      the insurance companies have a duty to defend and indemnify the Company
      under their policies of insurance relating to claims asserted against the
      Company by the EPA and by the Coeur d'Alene Indian Tribe.  In two
      separate decisions issued in August 1992 and in March 1993, the court
      ruled that the named primary insurance companies had a duty to defend the
      Company in the Tribe's lawsuit, but that no carrier had a duty to defend
      the Company in the EPA proceeding.  The Company has not reduced its
      environmental accrual to reflect any anticipated insurance proceeds.

           The Records of Decision with respect to both the populated and
      nonpopulated areas for the Bunker Hill Site indicate that future
      remediation costs total approximately $93.0 million.  Additionally, the
      federal government has asserted that they have incurred approximately
      $17.0 million in past costs at the site.  Because CERCLA assigns joint
      and several liability among the PRPs, any one of the PRPs, including the
      Company, could be assessed the entire cost of remediation.  However,
      based upon the terms of the consent decrees and related agreements for
      the Bunker Hill and Leadville Sites, as described above, the Company has
      accrued an amount for the Company's share of such remediation and other
      costs that management presently believes is the most likely amount that
      the Company will be required to fund.  Based upon this analysis, in the
      fourth quarter of 1993, the Company increased its allowance for CERCLA
      Superfund Site remedial action costs at the Bunker Hill and Leadville
      Sites by approximately $0.2 million and $0.3 million, respectively.  The
      total allowance for liability for remedial activity costs at the Bunker
      Hill and Leadville Sites is $10.2 million and $0.5 million, respectively,
      as of December 31, 1993.  Other than consulting work necessary for the
      implementation of the Company's allocated portion of the remedial
      activity at these sites, the Company's accruals do not include any future
      legal or





                                      F-22
<PAGE>   68
      consulting costs.  The Company does not believe that these costs will be
      material.  In addition, the Company has not included any amounts for
      unasserted claims at these or any other sites because the Company's
      potential liability has not been asserted or established and amounts, if
      any, of potential liability are impossible to determine.  During 1993,
      1992 and 1991, the Company expensed approximately $0.8 million, $8.6
      million and $2.8 million, respectively, in connection with the Superfund
      Sites.

           In December 1993, Industrial Contractors Corp. (ICC) served the
      Company with a complaint in Federal District Court for the District of
      Idaho alleging that the Company failed to comply with the terms of the
      contract between the Company and ICC relating to the earth moving work
      contracted to ICC at the Company's Grouse Creek gold project.  ICC has
      alleged that the Company owes ICC in excess of $5.0 million not
      previously paid, including an approximate $1.0 million retention
      currently held by the Company under the terms of the contract.  The
      Company terminated ICC's work at the Grouse Creek gold project effective
      November 26, 1993, pursuant to its rights in the contract and is
      proceeding to rebid the second season of work originally contracted to
      ICC.  The Company has answered the complaint denying the allegations of
      ICC and has filed a counterclaim against ICC in excess of $2.0 million
      for damages incurred by the Company as a result of ICC's failure to
      comply with the terms of the contract.  The litigation is in the early
      stages of discovery; however, the Company hopes to be able to mediate the
      dispute with ICC prior to proceeding to trial.

           A jury trial is scheduled to commence in March 1994 in Idaho State
      District Court with respect to a lawsuit previously filed against the
      Company by Star Phoenix Mining Company (Star Phoenix), a former lessee of
      the Star-Morning Mine, over a dispute between the Company and Star
      Phoenix with respect to the Company's November 1990 termination of Star
      Phoenix's lease of the Star-Morning Mine property.  Star Phoenix, which
      is in bankruptcy, alleges the Company wrongfully terminated the lease
      agreement and interfered the Star Phoenix's contractual relationship with
      a major vendor and the purchase of concentrates for the Star Phoenix
      operations.  In addition, certain principals of Star Phoenix who
      guaranteed a portion of the Star Phoenix obligations have made similar
      claims against the Company.  In each case the plaintiffs have asserted
      that they have incurred damages amounting to millions of dollars as a
      result of the Company's actions.  It is the Company's position that the
      plaintiffs' claims are without merit and that the Company terminated the
      lease agreement in accordance with the terms of the agreement.  The
      Company believes it has sufficient defenses to all the plaintiffs'
      claims, and that the Company will ultimately prevail in this litigation.

           The Company is subject to other legal proceedings and claims which
      have arisen in the ordinary course of its business and have not been
      finally adjudicated.  These actions when ultimately concluded and
      determined and any remaining unaccrued potential liability at the
      Superfund sites addressed above, will not, in the opinion of management,
      have a material effect on results of operations or the financial
      condition of the Company and its subsidiaries.

Note 9:    Employee Benefit Plans

           The Company and certain subsidiaries have pension plans covering
      substantially all employees.  One plan covering eligible salaried and
      hourly employees provides retirement benefits and is based on the
      employee's compensation during the highest 36 months of the last 120
      months





                                      F-23
<PAGE>   69
      before retirement.  Three other pension plans covering eligible hourly
      employees provide benefits of stated amounts for each year of service.
      It is the Company's policy to make contributions to these plans
      sufficient to meet the minimum funding requirements of applicable laws
      and regulations, plus such additional amounts, if any, as the Company and
      its actuarial consultants consider appropriate.  Contributions are
      intended to provide not only for benefits attributed to service to date,
      but also for those expected to be earned in the future.  Plan assets for
      these plans consist principally of equity securities, insurance contracts
      and corporate and U.S. government obligations.

           Net periodic pension cost (income) for the plans consisted of the
      following in 1993, 1992 and 1991 (in thousands):

           In 1988, 1991 and again in 1992, the Company offered a special early
      retirement option to participants in the Hecla retirement plan with no
      actuarial reduction in their accrued benefit for early retirement.  The
      costs associated with the 1988 special early retirement program were
      accrued in 1988 and are being funded out of general corporate funds until
      the participant reaches normal retirement age or age 60 with 30 years of
      service, at which time payments will be made by the related pension
      trust.  The 1991 and 1992 special early retirement programs are being
      funded out of the related pension trust.

           The Company provides certain postretirement benefits, principally
      health care and life insurance benefits for qualifying retired employees.
      The costs of these benefits are being funded out of general corporate
      funds.  Prior to 1992, the cost of some of these benefits was expensed
      when payments were made.  Other health care and life insurance benefits
      had been previously accrued.  Effective January 1, 1992, the Company
      adopted Statement of Financial Accounting Standards No. 106, "Employers'
      Accounting for Postretirement Benefits Other Than Pensions" (SFAS No.
      106), which





                                      F-25
<PAGE>   71
      requires that these postretirement benefits be accrued over the period in
      which active employees provide services to the Company.  At January 1,
      1992, the cumulative effect of recording these postretirement benefits
      was to increase the 1992 net loss by $1.6 million or $0.051 per share.

           Net periodic postretirement benefit cost for 1993 and 1992 included
      the following components (in thousands):

           The actuarial assumptions used in determining the Company's
      accumulated postretirement benefit obligation are provided in the table
      below.  Due to the short period which the Company provides medical
      benefits to its retirees, the increases in medical costs are assumed to
      be 6% in each year.  A 1% change in the assumed health care cost trend
      rate would not have a significant impact on the accumulated
      postretirement benefit obligation or the aggregate of service and
      interest cost for 1993 or 1992.

           The Company has a Deferred Compensation Plan which permits eligible
      officers and directors to defer a portion of their compensation.  The
      deferred compensation, which together with Company matching amounts and
      accumulated interest is accrued but unfunded, is distributable in cash
      after retirement or termination of employment, and at December 31, 1993
      and 1992, amounted to approximately $1.2 million.  The Company has
      insured the lives of certain officers, who participate in the deferred
      compensation program, to assist in the funding of the deferred
      compensation liability.  The Company is the owner and beneficiary of the
      insurance policies.  At

<PAGE>   72
      December 31, 1993, the cash surrender value of these policies was $2.4
      million, which is net of $2.2 million of policy loans.

           The Company has an employees' Capital Accumulation Plan (Plan) which
      is available to all salaried and certain hourly employees after
      completion of one year of service.  Employees may contribute from 2% to
      10% of their compensation to the Plan.  Effective January 1, 1993,
      nonhighly compensated employees may contribute up to 15%.  The Company
      makes a matching contribution of 25% of an employee's contribution up to,
      but not exceeding, 5% of the employee's earnings.  The Company's
      contributions for both 1993 and 1992 were approximately $158,000 and
      $149,000 for 1991.

Note 10:   Shareholders' Equity

      Preferred Stock

           In June 1993, the Company completed a public offering of 2.3 million
      shares of Series B Cumulative Convertible Preferred Stock, par value
      $0.25 per share (the Preferred Shares).  The shares were sold for $50
      each and the Company received net proceeds of $110,346,000 from the
      offering.  Holders of the Preferred Shares are entitled to receive
      cumulative cash dividends at the annual rate of $3.50 per share payable
      quarterly, when and if declared by the Board of Directors.

           The Preferred Shares are convertible in whole or in part at the
      option of the holders thereof, into shares of common stock at an initial
      conversion price of $15.55 per share of common stock.  The Preferred
      Shares are not redeemable by the Company prior to July 1, 1996.  After
      such date, the shares will be redeemable at the option of the Company at
      any time, in whole or in part, initially at $52.45 per share and
      thereafter at prices declining ratably on each July 1 to $50 per share on
      or after July 1, 2003.

           Holders of the Preferred Shares have no voting rights except if the
      Company fails to pay the equivalent of six quarterly dividends.  If these
      dividends are not paid, the holders of Preferred Shares, voting as a
      class, shall be entitled to elect two additional directors.  The holders
      of Preferred Shares also have voting rights related to certain amendments
      to the Company's Articles of Incorporation.

           The Preferred Shares rank senior to the common stock and any
      outstanding shares of Series A Preferred Shares.  The Preferred Shares
      have a liquidation preference of $50 per share plus all accrued and
      unpaid dividends.


      Shareholder Rights Plan

           In 1986, the Company adopted a Shareholder Rights Plan.  Pursuant to
      this plan, holders of common stock received one preferred share purchase
      right for each common share held.  The plan was amended effective
      November 9, 1990.  The rights will be triggered once an Acquiring Person,
      as defined, acquires 15% or more of the Company's outstanding common
      shares.  The 15% triggering threshold may be reduced by the Board of
      Directors to not less than 10%.  When exercisable, the right would,
      subject to certain adjustments and alternatives, entitle rightholders,
      other than the Acquiring Person or group, to purchase common stock of the
      Company or the acquiring company having a market value of twice the
      $47.50 exercise price of the right.  The rights are nonvoting, may be
      redeemed at any time





                                      F-27
<PAGE>   73
      at a price of 5 cents per right prior to the tenth day after an Acquiring
      Person acquires 15% of the Company's common stock, and expire in 1996.
      Additional details are set forth in the Rights Agreement filed with the
      Securities and Exchange Commission on May 19, 1986, and in the amendments
      dated November 29, 1990 and September 30, 1991.

      Stock Option Plans

           In connection with the Company's 1991 acquisition of CoCa Mines Inc.
      (CoCa), the Company assumed three preexisting CoCa employee stock option
      plans (CoCa Plans), and converted all options then outstanding under the
      CoCa Plans into options to acquire shares of the Company's common stock.
      No further options will be granted under these CoCa Plans.

           The Company adopted a nonstatutory stock option plan in 1987.  The
      plan provides that options may be granted to certain officers and key
      employees to purchase common stock at a price of not less than 50% of the
      fair market value at the date of grant.  The plan also provides that
      options may be granted with a corresponding number of stock appreciation
      rights and/or tax offset bonuses to assist the optionee in paying the
      income tax liability that may exist upon exercise of the options.  All of
      the outstanding stock options under the 1987 plan were granted at an
      exercise price equal to the fair market value at the date of grant and
      with an associated tax offset bonus.  Outstanding options under the 1987
      plan are immediately exercisable for periods up to ten years.  At
      December 31, 1993 and 1992, there were 129,148 and 101,748 shares,
      respectively, available for grant in the future under the plan.  The plan
      expires in 1997.

           The Company had an incentive stock option plan under which options
      were granted to purchase common stock at a price not less than the fair
      market value at date of grant.  This plan expired in 1992.

           The aggregate amounts charged (credited) to operations in connection
      with the plans were $309,000, $(165,000) and $170,000 in 1993, 1992 and
      1991, respectively.

           Net sales, costs and identifiable assets of each segment are those
      that are directly identified with those operations.  General corporate
      assets consist primarily of cash, receivables, investments and corporate
      property, plant and equipment.  As a result of depressed metals prices,
      operations were suspended at the Greens Creek mine in April 1993 and the
      property was placed on a care-and-maintenance basis pending resumptions
      of operations.  At December 31, 1993, the Company's recorded net book
      value of identifiable assets of the Greens Creek mine was approximately
      $50.3 million.  This amount has been classified in the Idle Facilities
      category at December 31, 1993.

                 (1)  See Note 1 of Notes to Consolidated Financial Statements
                      for a description of the Company's depreciation,
                      depletion and amortization policies.  The amounts in 1993
                      include the acquisition of Mountain West Bark Products,
                      Inc. for the issuance of 655,000 shares of the Company's
                      common stock valued at $6.3 million, of which $4.6
                      million was allocated to property, plant and equipment.
                      The amounts in 1992 include the acquisition of mineral
                      concessions for the issuance of 184,862 shares of the
                      Company's common stock valued at $1.8 million.

                      capital expenditures.

                 (4)  Represents the write-down of the Company's interest in
                      several mining properties.  See Note 5 of Notes to
                      Consolidated Financial Statements for discussion.

                 (5)  Reflects reclassification made in 1992 of the Company's
                      investment in the mining properties of Consolidated
                      Silver Corporation from other investments to mining
                      properties.

referred to herein collectively as the "Borrowers" and individually as a
"Borrower"), the banks named on the signature pages hereto (collectively, the
"Banks" and each individually, a "Bank"), and MASE WESTPAC LIMITED, NEW YORK
BRANCH, a New York State licensed branch of Mase Westpac Limited, an authorized
institution under the Banking Act of 1987 in England, as agent for the Banks
(in such capacity, together with its successors in such capacity, the "Agent").

                                    RECITALS

         WHEREAS, the Borrowers, certain banks and the Agent entered into a
Credit Agreement, dated as of January 25, 1993, as amended April 12, 1993 and
August 11, 1993 (such Credit Agreement as so amended, the "Credit Agreement"),
pursuant to which the banks party thereto agreed, subject to the terms and
conditions of the Credit Agreement, to provide financing to the Borrowers in an
aggregate amount not to exceed at any time the lesser of Twenty-Four Million
Dollars ($24,000,000), as such amount is reduced from time to time pursuant to
the terms of the Credit Agreement, or the Borrowing Base (as defined in the
Credit Agreement); and

         WHEREAS, the parties hereto desire to amend the Credit Agreement to
increase the maximum limit for borrowing and to make certain other amendments
to the Credit Agreement and other Loan Documents as provided herein;

                                   AGREEMENT

         NOW, THEREFORE, in consideration of the premises and the mutual
agreements contained herein, and for other good and valuable consideration
(including without limitation the consideration recited in the Credit
Agreement), the receipt and sufficiency of which are hereby acknowledged, the
parties hereto agree as follows:

         1. Definitions.  Capitalized terms used herein and not otherwise
defined herein shall have the meanings ascribed thereto in the Credit
Agreement.

         2. Addition of New Bank; Reallocation of Banks' Interests in Credit.

purposes under the Credit Agreement and the other Loan Documents, each as
amended hereby, to the extent of such Bank's interest as set forth opposite
such Bank's name on the





<PAGE>   2
signature pages hereto.  Each Bank shall have the same rights and benefits as
against the Borrowers and the same obligations to the Borrowers as it would
have had as if it were a Bank (as defined in the Credit Agreement) to the
extent of its interest as set forth opposite such Bank's name on the signature
pages hereto, or if such Bank was an original Bank under the Credit Agreement,
as if its interest under the Credit Agreement were the same as that set forth
opposite such Bank's name on the signature pages hereto.  All references in the
Credit Agreement and the other Loan Documents, each as amended hereby, to the
Banks shall as of the effective date hereof and thereafter be construed as a
reference to the Banks named on the signature pages hereto, each to the extent
of its interest as set forth opposite such Bank's name on the signature pages
hereto.  All references in the Credit Agreement and the other Loan Documents to
any Bank's pro rata share of the Commitment or of any Advances and all
references of similar import shall be deemed to be a reference to such Bank's
pro rata share as set forth opposite such Bank's name on the signature pages
hereto.

2.4  Adjustment

         The parties agree that Purchaser shall conduct an audit of the
Financial Statements and, as soon as reasonably practicable and not later than
fourteen (14) days prior to the Closing Date, prepare and submit to Sellers an
audited balance sheet for the Corporation as of the Statement Date ("Final
Balance Sheet").  The Final Balance Sheet shall be prepared in accordance with
generally accepted accounting principles and shall be in a format consistent
with the balance sheet comprising a part of the Financial Statements.

         The Final Balance Sheet shall be compared against the balance sheet
comprising the balance sheet in the Financial Statements for the period ending
on the Statement Date.  The audit shall accept the values stated in the
Corporation's Financial Statements for the fixed assets and the volume and
value of fungible inventory actually in the Corporation's possession on the
Statement Date; in the event such fixed assets were not actually in the
Corporation's possession on the Statement Date, an adjustment shall be made as
a





                                      -12-
<PAGE>   18
portion of the following procedure.  The aggregate difference between the
amount of any and all accounts on the Final Balance Sheet and the amount of any
and all accounts on the balance sheet in the Financial Statements at the
Statement Date (the "Aggregate Difference"), if less than one hundred
eighty-six thousand dollars ($186,000) shall be paid to the appropriate party,
as follows: if the Aggregate Difference results in net reduction of the
accounts on the Final Balance Sheet, then Sellers, jointly and severally, agree
to pay to Purchaser the entire amount of the Aggregate Difference.  If the
Aggregate Difference results in net increase of accounts on the Final Balance
Sheet, Purchaser shall pay Sellers the entire amount of the Aggregate
Difference.  If the Aggregate Difference exceeds one hundred eighty-six
thousand dollars ($186,000), neither party shall be obligated to make any
payment or to close the transaction contemplated in this Agreement, as
specified in Article 6 hereof.  Any payment pursuant to this section shall be
made to Purchasers or Sellers, respectively, in cash or certified funds, at
December 31, 1993.

         The Sellers shall have ten (10) days from their receipt of the Final
Balance Sheet to review the Final Balance Sheet and provide Purchaser with any
written objections to the balance sheet presentation.  In the event the Sellers
do not object to the Final Balance Sheet within said period of time, the Final
Balance Sheet shall be deemed correct and shall be used for the purposes of the
adjustment.  In the event that the Sellers object to the Final





                                      -13-
<PAGE>   19
Balance Sheet, the parties shall endeavor to resolve their differences within a
period of four (4) days; provided, however, if the parties are unable to
resolve their differences, Closing shall take place on the Closing Date, and
the Final Balance Sheet shall be prepared by Coopers & Lybrand.  The Purchaser
and Sellers shall equally share the cost of the accounting firm's preparation
of the Final Balance Sheet.  The balance sheet prepared by Coopers & Lybrand
shall be the Final Balance Sheet for the purposes of the adjustment, and the
Aggregate Difference, if any, shall be paid by the appropriate party within ten
(10) days of receipt thereof, if the Final Balance Sheet is provided after
December 21, 1993.

              nature of its business now conducted by it requires it to be so
              registered, licensed or qualified and all such registrations,

<PAGE>   23
         74,506 common shares have been duly issued and are outstanding as
         fully paid and non-assessable shares, and 29,871 are issued and held

         Corporation might be commenced with any reasonable likelihood of
         success.

                                      -23-
<PAGE>   29
         Corporation as the Corporation may determine.  The Corporation is not
         subject to any legislation or any judgment, order or requirement of
         any court or governmental authority which is not of general
         application to persons carrying on a business similar to the Business
         of the Corporation.  To the best of the knowledge of the Sellers,
         there are no facts or circumstances which could materially adversely

         obligations under any one or more contracts, agreements (written or
         oral), commitments, indentures or other instruments to which it is a
         party or by which it is bound and there exists no state of facts
         which, after notice or lapse of time or both, would constitute such a
         default or breach.  All such contracts, agreements, commitments,
         indentures and other instruments are now in good standing and in full
         force and effect without amendment thereto, the Corporation is
         entitled to all benefits thereunder and, to the best of the knowledge
         of the Sellers, the other parties to such contracts, agreements,
         commitments, indentures and other instruments are not in default or
         breach of any of their obligations thereunder.  Except for Sellers'
         guarantees and pledges of





                                      -24-

         security in relation to the Key Bank Debt and the Bank of Commerce
         Debt, there are no contracts, agreements, commitments, indentures or
         other instruments under which the Corporation's rights or the
         performance of its obligations are dependent upon or supported by the
         guarantee of or any security provided by any other person.

(20)     Tax Liabilities.  Except as disclosed in Schedule D, to the best of

         all fiscal periods up to and including the fiscal period ended August
         31, 1993.  As of the date hereof, no taxation authority has disagreed
         with or raised any material issues concerning the information
         contained in any tax returns filed by the Corporation.  Adequate
         provision has been made for taxes which may be payable by the
         Corporation for the current period for which tax returns are not yet
         required to be filed and all installments of taxes in the current year
         have been paid in accordance with the applicable statutory
         requirements.  There are no agreements, waivers or other arrangements
         providing for an extension of time with respect to any





                                      -25-
<PAGE>   31
         assessment or reassessment or the filing of any tax return or payment
         of any tax, governmental charge or deficiency by the Corporation and
         there are no actions, suits, proceedings or investigations for claims
         now pending or threatened against the Corporation in respect of taxes,
         governmental charges or assessments or any matters under discussion
         with any governmental authority relating to the same.  The Corporation
         has withheld from each payment made to any of its officers, directors
         or employees, present and past, the amount of all taxes, including but
         not limited to income tax and other deductions required to be withheld
         therefrom and has paid the same to the proper tax or other receiving
         officer within the time required under any applicable legislation.

(21)     Other Returns.  To the best of the knowledge of the Sellers, the
         Corporation has filed all returns required and called for under any
         statutes, regulations of any jurisdiction in which the failure to file
         such returns would have a material adverse effect on its assets or
         business and such returns were completed substantially in accordance
         with the provisions of such statutes.

(22)     Compliance with Laws.  To the best of the knowledge of the Sellers,
         the Corporation is not in violation of any federal, state, municipal
         or other law, regulation or order of any

         government or governmental or regulatory authority, domestic or
         foreign.

         amendments) of all contracts, leases and other documents referred to
         in this Agreement or any Schedule hereto or required to be disclosed

         made available to the Purchaser.

(24)     Disclosure.  No representation or warranty contained in this Section
         3.1, and no statement contained in any Schedule, certificate, list,
         summary or other disclosure document provided or to be provided to the
         Purchaser pursuant hereto or in connection with the transactions
         contemplated hereby contains or shall contain any untrue statement of
         a material fact, or omits or shall omit to state any material fact

         Board of Directors approval prior to the Closing Date, the Purchaser
         has good right, full corporate power and authority to enter into this
         Agreement and to purchase the Corporation's Shares from the Sellers
         and to issue the Purchaser's Shares to the Sellers in the manner
         contemplated herein and to perform all of the Purchaser's obligations
         under this Agreement.  The Purchaser has taken all necessary or
         desirable actions, steps and corporate and other proceedings to
         approve or authorize, validly and effectively, the entering into of,
         and the execution, delivery and performance of, this Agreement and the
         purchase of the Corporation's Shares from the Sellers and the issue of
         the Purchaser's Shares to the Sellers.  Except as hereinabove
         provided, this Agreement is a legal, valid and binding obligation of
         the Purchaser, enforceable against it in accordance with its terms
         subject to the laws affecting the enforcement of creditors rights
         generally and the availability of discretionary judicial remedies.

(2)      Status.  The Purchaser is a corporation duly incorporated and validly
         subsisting in all respects under the laws of its jurisdiction of
         incorporation.

(3)      No Violation.  The execution, delivery and performance of this
         Agreement and each of other agreements contemplated or referred to
         herein by the Purchaser, and the completion of the transactions
         contemplated hereby, shall not constitute or result in a violation or
         breach of or default under, or cause the acceleration of any
         obligations of the Purchaser under:

         (a)  any term or provision of the certificate of incorporation,
              by-laws or other constating documents of the Purchaser,

         (b)  the terms of any agreement (written or oral), indenture,
              instrument or understanding or other obligation or restriction to
              which the Purchaser is a party or by which it is bound, or

         (c)  any term or provision of any of the licenses or any order of any
              court, governmental authority or regulatory body or any law or
              regulation of any jurisdiction in which the Business of the
              Purchaser is carried on.

         at Closing shall be duly authorized and validly issued and such shares
         when issued will be fully paid and non-assessable.  Subject to Section

<PAGE>   35
         shall not be registered under the Securities Act of 1933 or any
         comparable state securities law and shall therefore be held by Sellers
         as restricted stock for investment purposes.  Each certificate for the
         Purchaser's Shares shall contain the following legend:

                  "The shares represented by this certificate have not been
              registered under the Securities Act of 1933, as amended, or under
              the securities laws of any state or other jurisdiction and may
              not be sold, offered for sale or otherwise transferred unless
              registered and qualified under said Act and applicable state's
              securities laws or unless the company receives an opinion in
              acceptable form and scope of counsel satisfactory to the company
              that registration, qualification or such other actions are not
              required under any such laws."

(5)      Compliance with Laws.  The Purchaser is not in violation of any
         federal, state, municipal or other law, regulation or order of any
         government or governmental or regulatory authority, domestic or
         foreign, the violation of which would have a material adverse effect
         on the Purchaser and its consolidated subsidiaries taken as a whole.

         Sellers pursuant hereto or in connection with the transactions
         contemplated hereby contains or shall contain any untrue statement of

4.1  Survival of Representations and Warranties

         The representations, warranties and covenants contained in Article 3
shall survive the Closing and shall continue in full force and effect

<PAGE>   37
             (ii) the representations, warranties and covenants relating to tax
                  liabilities for a particular taxation year shall continue
                  until the expiration of the period (if any) during which an
                  assessment, reassessment or other form of recognized document
                  assessing liability for tax, interest or penalties in respect
                  of such taxation year under applicable legislation could be
                  issued, assuming that the Corporation or the Purchaser, as
                  the case may be, does not file any waiver or similar document
                  extending such period as otherwise determined; and

            (iii) there shall be no time limit in respect of the
                  representations, warranties and covenants relating to tax
                  liabilities based upon any misrepresentation made or fraud
                  committed in the filing of a return or in supplying
                  information for the purposes of the United States Internal
                  Revenue Code or any other legislation imposing a tax.

         Sellers shall cause all necessary steps and corporate proceedings to
         be taken to permit the Corporation's Shares to be duly and regularly

         or other agreements or commitments of any character obligating it to

         dividend or other distribution (whether in cash, stock or property)
         with respect to its capital stock; (iv) redeem, purchase or otherwise
         acquire, directly or indirectly, any of its capital stock; (v) enter
         into any agreement, commitment or transaction (including, but not
         limited to, any capital expenditure or sale of assets), except for the
         agreements specified in Section 5.1(3) and other than for an aggregate
         amount not exceeding $10,000 which shall be necessary in the ordinary
         course of business; (vi) grant any increase in the compensation
         payable or to become payable by the Corporation to any of their
         respective directors, officers or employees, or any increase in or new
         agreements or arrangements providing for any bonus, insurance, pension
         or other employee benefit plan, payment or arrangement (including, but
         not limited to, the granting of stock options or stock appreciation
         rights) made to, for or with any director, officer or employee; (vii)
         enter into any employment





                                      -35-

         of this Agreement, Sellers shall cause the Corporation to make
         available to Purchaser access to Seller's Properties and sources of
         supply for scoria and peat in order to enable Purchaser, at its
         expense, to undertake a program of exploratory trenching to verify the
         color, quantity, and extent of the deposits and sources supplying the
         Corporation's scoria and peat.

(6)      Sale of Purchaser's Shares.  Each Seller shall notify the Purchaser
         when it has disposed of all of Purchaser's Shares held by such Seller.

5.2  Covenants by the Purchaser

         The Purchaser covenants to the Sellers that it shall do or cause to be
done the following:

(1)      Issue of Purchaser's Shares.  At or before the Closing Time, the
         Purchaser shall cause all necessary steps and corporate





                                      -36-
<PAGE>   42
         proceedings to be taken in order to issue and allot the Purchaser's
         Shares to the Sellers pursuant to Section 2.3 hereof.

(2)      Registration and Listing of Purchaser's Shares.  Subject to the
         conditions specified below, the Purchaser shall as promptly as
         practicable prepare and file with the SEC no later than ten (10)
         business days after Closing and thereafter use its best efforts to
         cause to become effective as promptly as practicable a registration
         statement for a public offering to be made on a continuous or delayed
         basis pursuant to Rule 415 under the Securities Act (or any successor
         to such rule permitting securities to be registered on a continuous or
         delayed basis in the future) covering the Purchaser's Shares in order
         to permit the public sale or disposition of the Purchaser's Shares by
         the Sellers;

         (a)  The Purchaser will prepare and file with the SEC amendments and
              supplements to such registration statement and the prospectus
              used in connection therewith (i) as may be necessary to keep such
              registration statement effective under the Securities Act for a
              period of two (2) years from the Closing Date (subject to earlier
              termination in the event all the Purchaser's Shares held by the
              Sellers have been sold prior to the end of such two-year period).





                                      -37-
<PAGE>   43

         (b)  The Purchaser will furnish to the Sellers such number of copies
              of the registration statement and such prospectus and amendment
              or supplement as the Sellers shall reasonably request.

         (c)  The Purchaser will notify the Sellers in the event any prospectus
              then in use contains any untrue statement of a material fact or
              any omission of a material fact necessary to make the statements
              therein in light of the circumstances under which they are made
              not misleading.

         (d)  The Purchaser will use its best efforts to register or qualify
              such Purchaser's Shares covered by such registration statement
              under such other securities or "blue sky" laws of such
              jurisdictions as any Sellers of Purchaser's Shares representing
              more than 15% of the total number of securities covered by such
              registration statement shall reasonably request, and do any and
              all other acts and things that may be necessary or advisable to
              enable such Sellers to consummate the disposition in such
              jurisdictions of such Purchaser's Shares owned by such Sellers;
              provided, however, that the Purchaser shall not for any such
              purpose be required to qualify generally to do business as a
              foreign corporation in any jurisdiction wherein it would not but
              for the





                                      -38-
<PAGE>   44
              requirements of this clause (d) be obligated to be so qualified,
              to subject itself to taxation in any such jurisdiction or to
              consent to general service of process in any such jurisdiction.

         (e)  If the Purchaser shall furnish to the Sellers a certificate
              signed by the Chairman and Chief Executive Officer, the President
              or any Vice President of the Purchaser stating that the Purchaser
              would be required to disclose in such registration statement or
              amendment or supplement to such registration statement and the
              prospectus used in connection therewith a material business
              situation, transaction or negotiation affecting the Purchaser not
              otherwise then required in the opinion of the Purchaser's
              counsel, by law to be publicly disclosed and such disclosure
              would, in the opinion of the Purchaser, materially and adversely
              affect such business situation, transaction or negotiation, the
              obligation of the Purchaser to file such registration statement
              or the prospectus used in connection therewith (or to keep such
              registration statement or prospectus effective) shall be tolled
              until the earlier to occur of (A) the date of public disclosure
              of such material business situation, transaction or negotiation
              or (B) the date on which the Purchaser would no longer be
              required





                                      -39-
<PAGE>   45
              to make such disclosure; provided, however, that such period may
              not be tolled for more than sixty (60) days.

         (f)  The Purchaser shall use its best efforts to list the Purchaser's
              Shares issued to Sellers on the New York Stock Exchange.

         (g)  The Purchaser shall pay all Registration Expenses in connection
              with the registration of Purchaser's Shares; provided that the
              Sellers shall pay all underwriting discounts and commissions and
              transfer taxes, if any (and any other expenses specifically
              excluded from the definition of Registration Expenses), relating
              to the sale or disposition of Purchaser's Shares by a Seller
              pursuant to a registration statement effected pursuant to this
              Agreement.

         Notwithstanding the foregoing, the Purchaser shall not be obligated to
enter into any type of underwriting agreement.

         Each Seller who holds Purchaser's Shares agrees that upon receipt of
any notice from the Purchaser of the happening of any event of the kind
described in clause (c) of this Section 5.2(2), such holder will forthwith
discontinue disposition of Purchaser's Shares pursuant to the registration
statement covering such Purchaser's Shares until the Sellers receive copies of
a prospectus





                                      -40-
<PAGE>   46
supplemented or amended so that the prospectus does not contain any untrue
statement of a material fact or any omission of a material fact necessary to
make the statements therein in light of the circumstances under which they are
made not misleading.  In addition, each Seller who holds Purchaser's Shares
agrees that upon receipt of a certificate from Purchaser of the kind described
in clause (e) of this Section 5.2(2), such holder will forthwith discontinue
disposition of Purchaser's Shares pursuant to the registration statement
covering such Purchaser's Shares until the earlier of (A) the date of public
disclosure of such material business situation, transaction or negotiation or
(B) the date on which the Purchaser would no longer be required to make such
disclosure.

         (c)  In case of any claim by a third party against the Indemnified
              Party in respect of which the Indemnifying Party may be required
              to provide indemnification pursuant to this Article, such
              Indemnifying Party shall be entitled to assume the defence of
              such claim, and after notice from such Indemnifying Party to the
              Indemnified Party of the Indemnifying Party's election to assume
              the defence thereof, the Indemnifying Party shall not be liable
              to the Indemnified Party for any legal or other expenses
              subsequently incurred by the Indemnified Party in connection with
              the defence thereof, other than reasonable costs of
              investigation, unless such Indemnifying Party does not actually
              assume the defence thereof following notice of such election.
              The Indemnified Party shall make available to the Indemnifying
              Party and its attorneys and other authorized representatives, at
              all reasonable times, and subject to confidentiality as to
              certain information, all books and records of the Indemnified
              Party relating to such claim and shall render to such
              Indemnifying Party such assistance as may reasonably be required
              in order to ensure proper and adequate defence of any such claim.

         (d)  The Indemnified Party shall not make any settlement of any such
              claim which might give rise to an obligation by the Indemnifying
              Party to indemnify it pursuant to this Article without the
              written consent of the Indemnifying Party.  If the Indemnifying
              Party desires to effect a bona fide compromise or settlement of
              any such claim and the Indemnified Party should unreasonably
              refuse to consent to such compromise or settlement, then the
              Indemnifying Party's liability under this Article with respect to
              such claim shall be limited to the amount so offered in
              compromise or settlement together with all legal and other
              expenses which may have been incurred prior to the date on which
              the Indemnified Party has refused to consent to such compromise
              or settlement.
