  respective Participating Interests  in the affected Exploration  or Production
  Area.


                                    ARTICLE VI

                             INTERESTS OF PARTICIPANTS

       6.1  INITIAL PARTICIPATING  INTERESTS.  The  Participants shall have  the
  following initial Participating Interests in all Assets:

                                Santa Fe  - 75%

                                Hecla -     25%

  Unless changed pursuant to  other provisions of this Agreement, all  costs and
  liabilities  incurred  in the  Operations shall  be  borne and  paid,  and all
  Assets acquired and Products  mined by  the Operations shall  be owned by  the
  Participants in proportion to the above percentage Participating Interests.

       6.2  CHANGES IN PARTICIPATING  INTERESTS.  A  Participant's Participating
  Interest shall be changed as follows:

            (a)  Upon an  election by a  Participant pursuant to  Section 6.3 to
  contribute  less  to  an  adopted  Program  and  Budget  than  the  percentage
  reflected  by  its  Participating Interest  in  the  affected  Exploration  or
  Production Area; or

            (b)  In the  event  of  default  by  a  Participant  in  making  its
  agreed-upon contribution  to an  adopted Program  and Budget,  followed by  an
  election by the other Participant to invoke Section 6.4(b); or


















                                       -12-







    18


            (c)  Upon  reduction of  Participating  Interest  to less  than  15%
  under Section 6.5; or

            (d)  Transfer  by a Participant of  less than  all its Participating
  Interest in accordance with Article XV; or

            (e)  Acquisition  of less than all  of the Participating Interest of
  the other Participant, however arising.

        The Production Area specified in  the Initial Feasibility Study  and any
  additional Area or  Areas designated as Production Area or Areas in accordance
  with  Section   9.4,    shall   be  treated  separately   for  calculation  of
  Participating Interests and the Participants'  Participating Interests in that
  Area  will  be designated  and  calculated separately  from  the Participating
  Interests relating to the Exploration Area.  The Manager hereby allocates  the
  Participants' Initial  Contributions to  the Production Area  specified in the
  Initial Feasibility  Study.  When  an additional Area  is initially designated
  as a Production Area, the Manager shall, no later than  three months after the
  establishment of such  Area by  adoption of the  Program, allocate  a cost  to
  such  Area, which cost  will be  approximately equal  to the aggregate  of the
  amounts which in the  reasonable opinion of the Manager have  been expended on
  the lands that  comprise such  Area.  The  amount allocated  shall be  divided
  between   the  Participants   in  direct   proportion   to  their   respective
  Participating  Interests  in  that  Area's  lands  immediately  preceding  the
  allocation.   All expenditure amounts not  so allocated to the Production Area
  shall  be  deemed  allocated  to  the  Exploration  Area.     A  Participant's
  Participating Interest in  an Area designated  as a  Production Area shall  be
  determined from amounts  allocated thereto and amounts  thereafter contributed
  pursuant to work programs and budgets for  the Production Area.  Participating
  Interests  in  such  Production Area  shall  not  be  affected by  changes  in
  Participants' Participating 




















                                       -13-







    19


  Interests in the  Exploration Area.  A Participant's Participating Interest in
  the  Exploration  Area shall  be  based  upon  amounts  contributed or  deemed
  contributed  to  the  Exploration  Area,  excluding  amounts  allocated  to  a
  Production Area.

       The Manager  also shall,  within three  months after  establishment of  a
  Production Area, allocate all personal property owned  by the Venture (and not
  previously  allocated to  a  Production Area)  to  either the  Production Area
  specified in the Initial Feasibility  Study, the newly established  Production
  Area or  the Exploration Area,  and thereafter the  Participating Interests of
  the  Participants  in   such  personal  property   shall  be   equal  to   the
  Participants'  respective Participating  Interests  in  the relevant  Area  as
  adjusted from time to time.

       6.3  VOLUNTARY REDUCTION IN PARTICIPATION.

            (a)  Pursuant to Section 9.6, a  Participant may elect to  limit its
  contributions to an adopted Program and Budget to  some lesser amount than its
  Participating  Interest  share   of  program  expenditures  in   the  affected
  Exploration or Production Area, or (2) elect to make no contribution.

            (b)  If a  Participant elects to  contribute to  an adopted  Program
  and Budget  in  some  amount  less than  its  Participating  Interest  in  the
  relevant Exploration  or Production Area,  or not to  contribute at all,  then
  the  Participating Interest of each Participant  in the relevant Area shall be
  recalculated at  the time  of election by  dividing:  (i)  the sum of  (1) the
  agreed value  of the Participant's initial  contribution, apportioned  to such
  Area  pursuant  to  Sections  5.1  and   6.2,  plus  (2)  the  total  of   the
  Participant's prior contributions  to such Area under Section 5.2 or allocated
  to  such  Area under  Section 6.2,  plus  (3) the  amount,  if any,  which the
  Participant has  elected to contribute  to the adopted Program  and Budget; by
  (ii) the  sum  of (1),  (2)  and  (3) above  for  all Participants;  and  then
  multiplying the result by one hundred.


















                                       -14-







    20


            (c)  If  the  consenting Participant(s)  in  a  Non-Consent  Program
  fail(s) to  spend at  least 90%  of the  Budget associated  with the  relevant
  Program,  then the  non-consenting  Participant shall  be entitled,  within 30
  days of being notified of  completion of the reduced Program, to pay its share
  of the  expenditures actually made  by the consenting  Participant and thereby
  maintain  its   Participating  Interest  in   the  affected  Area.     If  the
  non-consenting Participant fails  to contribute within such 30 day period, its
  Participating  Interest  shall be  reduced  in accordance  with  the foregoing
  provisions.

       6.4  DEFAULT IN MAKING CONTRIBUTIONS.

            (a)  If  a Participant  defaults in  making  a contribution  or cash
  call required  by an adopted Program and Budget  to which that Participant has
  elected to  contribute under Section  9.6, the non-defaulting Participant  may
  advance the  defaulted contribution  on behalf  of the  defaulting Participant
  and treat  the same,  together with  any accrued  interest, as  a demand  loan
  bearing  interest from  the  date  of the  advance  at  the rate  provided  in
  Section 10.3.  The failure to repay said loan upon demand  shall be a default.
  Each  Participant hereby grants to  the other a lien upon  its interest in the
  Properties and a security  interest in its rights under this  Agreement and in
  its Participating Interest  in other Assets,  and the  proceeds therefrom,  to
  secure  any  loan  made  hereunder,  including  interest  thereon,  reasonable
  attorneys  fees  and all  other  reasonable  costs  and  expenses incurred  in
  recovering the  loan  with interest  and in  enforcing such  lien or  security
  interest, or  both.   A non-defaulting  Participant may  elect the  applicable
  remedy  under this  Section  6.4(a)  or under  6.4(b),  or,  to the  extent  a
  Participant has a lien  or security interest under applicable law, it shall be
  entitled to its rights  and remedies at law and in equity.   All such remedies
  shall  be  cumulative.   The  election  of  one  or more  remedies  shall  not
  constitute a wavier of the right  to elect any other remedies.  At any time at
  the request of either Participant, 


















                                       -15-








    21


  the Participants  shall prepare, execute and  deliver and file or  record such
  instrument or instruments as are necessary to perfect such  liens and security
  interests.    Each  Participant  hereby  irrevocably  appoints  the  other its
  attorney-in-fact  to execute,  file and  record all  instruments  necessary to
  perfect or effectuate the provisions of this Section 6.4(a).

            (b)  The Participants acknowledge that if  a Participant defaults in
  making a  contribution, or a  cash call, or  in repaying  a loan, as  required
  hereunder, it  will be difficult  to measure  the damages resulting  from such
  default.  In the event of such default, as reasonable liquidated damages,  the
  non-defaulting Participant may,  with respect to  any such  default not  cured
  within 60  days after notice  to the defaulting  Participant of such  default,
  elect  one  of  the following  remedies  by  giving notice  to  the defaulting
  Participant:

                 (i)  For  a  default  relating exclusively  to  an  Exploration
       Program  and  corresponding Budget,  the  non-defaulting  Participant may
       elect to have the defaulting Participant's  Participating Interest in the
       Exploration Area permanently reduced  as provided in Section 6.3(b),  and
       further reduced by multiplying  the result by 90%.  Amounts  treated as a
       loan pursuant  to Section 6.4(a)  and interest thereon  shall be included
       in the calculation of the  defaulting Participant's reduced Participating
       Interest.    The non-defaulting  Participant's Participating  Interest in
       the Exploration Area shall, at  such time, become the  difference between
       100%  and the further  reduced Participating  Interest.   Such reductions
       shall be effective as of the date of the default.

                 (ii) For a default relating to a Development  or Mining Program
       and corresponding Budget,  at the non-defaulting  Participant's election,
       the defaulting Participant  shall be deemed  to have  withdrawn from  the
       relevant  Production  Area  under Section  12.2,  and  its  Participating
       Interest in the Production Area shall be converted to

       a Net Smelter  Returns ("NSR") interest  based upon  the appropriate  NSR
       interest  determined  pursuant  to  Section  6.5,  except  that  the  NSR
       percentage as  determined pursuant  to Section  6.5 shall  be reduced  by
       one-half  (i.e., a 3%  NSR shall be  a 1.5% NSR  and a 1%  NSR shall be a
       0.5% NSR), and the defaulting  Participant shall have the  opportunity to
       receive only such  NSR on Products, if  any, from the Production  Area as
       defined  at the time  of the  default until  such time as  the defaulting
       Participant has received  an amount equal  to its  contributions to  such
       Production Area.   The  defaulting Participant  shall thereafter have  no
       further right, title or interest in the relevant Production Area.

       6.5  ELIMINATION OF MINORITY INTEREST.

            (a)  Upon the  reduction of  a Participant's Participating  Interest
  in an Exploration Area  or Production Area to less than 15%, the Participant's
  Participating Interest in that Area shall be  converted as follows:  (1) to  a
  3% Net Smelter Returns interest on Products,  if any, produced from Properties
  in  such Area  that  are held  as an  undivided  fee simple  estate (including
  patented  mining  claims)  with  no  production  or  other  type  of  royalty,
  overriding royalty, advance  royalty or rental obligation that existed, or was
  contemplated by agreement to  arise in the future, as of the effective date of
  the  Earn-in Agreement, and/or  (b) to  a 1%  Net Smelter Returns  interest on
  Products, if  any, produced  from all  other Properties  in such  Area.   Such
  Participant shall be deemed to  have transferred to the  remaining Participant
  its Participating Interest  in the relevant  Area, but this transfer  will not
  include its Participating Interest in  the remainder of the Properties.   Such
  transfer will  be without  cost and  free and  clear of  royalties, liens,  or
  other   encumbrances  arising   by,  through   or   under  such   transferring
  Participant, except those  royalties and  other exceptions to  title described
  in Part  1 of Exhibit  A (if any),  Section 6.4,  this Section 6.5,  and those
  other interests and exceptions to which both Participants have 


















                                       -17-







    23


  given  their  written  consent  after   the  date  of  this  Agreement.    The
  transferring Participant shall execute and  deliver all instruments as  may be
  necessary to  effect  the  transfer  of  its  Participating  Interest  in  the
  relevant Area.  The transfer under  this Section 6.5(a) shall not relieve  the
  transferring  Participant  of  its  share  of  liabilities  to  third  persons
  (whether  such  accrued   before  or  after  such  transfer)  arising  out  of
  Operations  conducted  on the  relevant  Area  prior  to the  transfer.    The
  transferring  Participant's share  of  such liability  shall  be equal  to its
  Participating Interest in  the relevant  Area at the  time such liability  was
  incurred.

            (b)  Subject to  Section 15.2(k), the  Net Smelter Returns  interest
  provided  under  this   Section  6.5  shall  be  freely  transferable  by  the
  Participant  receiving  it  notwithstanding  any   other  provisions  of  this
  Agreement,  and it  shall be  binding upon  and inure  to the  benefit of  the
  Participants and their respective successors and assigns.

       6.6  CONTINUING LIABILITIES UPON ADJUSTMENTS  OF PARTICIPATING INTERESTS.
  No reduction of a Participant's  Participating Interest under this  Article VI
  shall  relieve such  Participant  of its  share of  any  reclamation or  other
  liability  arising  out  of  Operations  conducted  prior to  such  reduction,
  whether  it accrues before  or after such reduction,  whether it  was known or
  unknown at that  time, and whether it  becomes an enforceable right  before or
  after such  reduction.  For  purposes of this  Article VI, such  Participant's
  share of such  liability shall be equal  to its Participating Interest  in the
  relevant Exploration or Production Area  at the earliest time  such liability,
  or condition  giving rise  to such liability,  was created  or incurred.   The
  increased Participating Interest accruing  to a Participant as a result of the
  reduction of the other Participant's  Participating Interest shall be  free of
  royalties,  liens or  other  encumbrances arising  by,  through or  under such
  other Participant, other  than those existing at  the time of entry  into this
  Agreement  or  those to  which  both  Participants  have  given their  written
  consent.  An

    24


  adjustment to a Participating  Interest need not be evidenced during  the term
  of this Agreement by the  execution and recording of  appropriate instruments,
  but  each  Participant's  Participating  Interest   in  each  Exploration  and
  Production Area shall be shown  in the books of the Manager.   However, either
  Participant,  at any  time upon the  request of  the other  Participant, shall
  execute  and acknowledge  instruments reasonably  necessary  to evidence  such
  adjustment,  or to  grant or  confirm a  Net Smelter Returns  interest arising
  under this  Article VI, in  form sufficient for recording  in the jurisdiction
  where the Properties are located.


                                    ARTICLE VII

  methods  and actions  under  this Agreement.  The  Management Committee  shall
  consist of two  member(s) appointed by  Hecla and two  member(s) appointed  by
  Santa Fe.  Each Participant may appoint one  or more alternates to act in  the

  have one  vote on  the  Management Committee.   The  votes shall  be  weighted
  according  to  each  Participant's  Participating  Interest  in  the  relevant
  Exploration  or Production  area, and  decisions shall  be made  by a majority
  vote.  In case of a deadlock on a proposed  Program and Budget or on any other
  management matters  relating to  this Agreement  or the  Golden Eagle  Venture
  that 


















                                       -19-

  require a majority  approval of the  Management Committee,  the Manager  shall
  make the final decision.

            (b)  Notwithstanding   the   provisions  of   Section   7.2(a),  the
  following  decisions shall  require unanimous  approval  of the  Participating
  Interests in the relevant Exploration or Production Area.

                 (i)  Conduct  of any  business  unrelated to  Exploration,
       Mining, or Development;

       any dispute except for disputes involving less than $200,000;

                 (iii)     Borrowing  or  entering  into  any   form  of  credit

       Participating Interest;

                 (iv) Acquisition  or  disposition  of  Assets  valued  at  over

       as provided in Section 17.4.

                 (vi) Change of tax partnership status of the Venture  from that
  specified in Sections 4.2 and 4.3.

                 (vii)     An increase in the capital expenditures  contemplated
  in the Initial Feasibility Study by more than 25%.

       7.3  MEETINGS.  The Management  Committee shall hold regular  meetings at
  least quarterly  at a  place to  be  designated by  the Manager,  or at  other
  mutually  agreed places.    The  Manager shall  give  30  days notice  to  the
  Participants  of such regular meetings.   Additionally, either Participant may
  call a  special meeting  upon 15  days notice  to  the Manager  and the  other
  Participant.  In case of emergency, reasonable notice  of a special meeting to
  consider the 
















                                       -20-








    26


  emergency matter only shall suffice.  There shall be a quorum if at  least one
  member representing each  Participant is present  in person  or by  conference
  telephone; provided, however,  that if a quorum is  not present, those members
  in attendance may adjourn  the meeting to the  same time and place seven  days
  later, and  provided further  that a  quorum shall  be deemed  present at  the
  adjourned meeting if at  least one Participant is represented.  Each notice of
  a regular meeting shall include an itemized agenda prepared by the Manager  in
  the case  of a regular meeting, or  by the Participant calling  the meeting in
  the case of a special meeting,  but any matters may be considered  in any type
  of meeting with  the consent of all  Participants.  The Manager  shall prepare
  minutes of  all meetings and  shall distribute copies  of such minutes to  the
  Participants within 10  days after the meeting.   The minutes, when  signed by
  all Participants, shall  be the official record  of the decisions made  by the
  Management  Committee  and   shall  be  binding   on  the   Manager  and   the
  Participants.   If personnel employed  in Operations are  required to attend a
  Management Committee  meeting, reasonable  costs incurred  in connection  with
  such attendance shall be a Venture cost.  All other  costs of attendance shall
  be paid by the Participants individually.

       7.4  ACTION WITHOUT MEETING.  In addition to or  in lieu of meetings, the
  Management Committee may  hold telephone conferences, so long as all decisions
  are immediately confirmed in writing by the Participants.

       7.5  MATTERS REQUIRING  APPROVAL.   Except as otherwise  delegated to the
  Manager  in  Section  8.2,  the  Management  Committee  shall  have  exclusive
  authority to determine all management matters related to this Agreement.

  Budgets as provided in Article IX.

            (b)  The Manager  shall implement  the decisions  of the  Management
  Committee,  shall  make  all  expenditures  necessary  to  carry  out  adopted
  Programs,  and shall  promptly  advise the  Management  Committee if  it lacks

            (c)  The  Manager  shall:  (i) purchase  or  otherwise  acquire  all

                                       -22-







    28

  have the right to  contest in the courts or otherwise, the  validity or amount
  of any  taxes,  assessments  or  charges  if the  Manager  deems  them  to  be
  unlawful, unjust, unequal or  excessive, or to undertake  such other steps  or
  proceedings  as  the  Manager  may  deem  reasonably  necessary  to  secure  a
  cancellation,  reduction,  readjustment  or  equalization  thereof before  the
  Manager shall  be required  to pay  them, but  in no event  shall the  Manager
  permit or  allow  title  to  the  Assets to  be  lost  as the  result  of  the

  disposed of  such  violation through  performance,  or  payment of  fines  and
  penalties.  Manager shall be  solely responsible for fines and  penalties paid

    29


            (f)  The Manager shall prosecute and defend, but  shall not initiate
  without consent of the Management Committee, all litigation or  administrative

            (g)  The  Manager shall  provide insurance  for the  benefit of  the
  Participants as provided in Exhibit C.

  abandonment, surrender or  Transfer in the ordinary course of business, except
  that Properties may  be abandoned or  surrendered only as provided  in Article
  XIV.  However,  without prior authorization from the Management Committee, the
  Manager  shall not:   (i) dispose  of Assets in  any one  transaction having a
  value  in  excess  of  $50,000;  (ii)  enter   into  any  sales  contracts  or
  commitments  for Product;  (iii) begin a  liquidation of the  Venture; or (iv)

            (i)  The   Manager  shall   have  the   right  to   carry   out  its
  responsibilities   hereunder  through   agents,   Affiliates  or   independent
  contractors.

            (j)  The Manager shall perform or  cause to be performed  during the
  term of  this Agreement all assessment  and other work  or pay fees  or rental
  payments required  by law in  order to maintain  any unpatented mining  claims
  that  are included  in the Properties.   The Manager  shall have  the right to
  perform any  assessment  work  pursuant  to  a  common  plan  of  Exploration,
  Development  or Mining,  and  continued actual  occupancy  of such  claims and
  sites  shall not be required.   The Manager shall not  be liable on account of
  any determination by any 


















                                       -24-









    30


  court or  governmental  agency that  work performed  by the  Manager does  not
  constitute required  annual assessment work  or occupancy for  the purposes of
  preserving or  maintaining ownership  of the  claims, provided  that any  work
  done is  in accordance with the adopted Program and Budget.  The Manager shall
  timely record  with  the appropriate  county  and  file with  the  appropriate
  United States agency, affidavits in  proper form attesting to  the performance
  of  assessment  work  or  notices  of intent  to  hold  in  proper  form,  and
  allocating therein, to or for the benefit of each  claim, at least any minimum
  amount, if any, required by law to maintain such claim or site.

            (k)  If authorized  by the  Management Committee,  the Manager  may:
  (i)  locate, amend or  relocate any  unpatented mining  claim or mill  site or
  tunnel site,  (ii)  locate any  fractions  resulting  from such  amendment  or
  relocation, (iii)  apply  for patents  or  mining  leases or  other  forms  of
  mineral tenure  for any  such unpatented  claims or  sites,  (iv) abandon  any
  unpatented mining claims for  the purpose of locating mill sites  or otherwise
  acquiring  from the  United States rights  to the ground  covered thereby, (v)
  abandon any  unpatented mill sites  for the purpose of  locating mining claims
  or otherwise  acquiring from the  United States  rights to the  ground covered
  thereby,  (vi) exchange  with  or  convey to  the  United  States any  of  the
  Properties for  the purpose of acquiring rights to  the ground covered thereby
  or other  adjacent ground,  and (vii)  convert any unpatented  claims or  mill
  sites into one  or more leases  or other forms  of mineral tenure  pursuant to
  any federal law hereafter enacted.

            (l)  The Manager  shall keep  and maintain  all required  accounting
  and financial records pursuant to  the Accounting Procedure and  in accordance
  with customary cost accounting practices in the mining industry.





















                                       -25-









    31


            (m)  The  Manager shall  keep  each  Participant on  the  Management
  Committee  advised of  all  Operations  by submitting  to  each  the data  and
  information described  in Exhibit F  attached hereto within  a reasonable time
  after  such  data  and  information  is acquired  by  the  Manager.    At  all
  reasonable times the  Manager shall provide  the Management  Committee or  the
  representative  of  any Participant,  upon the  request of  any member  of the
  Management Committee, access to, and the right to  inspect, audit and copy all
  maps, drill logs,  core tests, reports, surveys, assays,  analyses, production
  reports, operations,  technical, accounting and  financial records, and  other
  information acquired  in Operations  that has  not been  provided pursuant  to
  Exhibit F;  such information will be  provided to the Management  Committee at
  the  cost  of  the  Venture  and  if  additional  copies  are  required  by  a
  Participant, they  will be  paid for by  that Participant.   In addition,  the
  Manager shall  allow the non-managing  Participant, at the  latter's sole risk
  and expense,  and subject  to reasonable  safety regulations,  to inspect  the
  Assets  and Operations  at all  reasonable times,  so long  as the  inspecting
  Participant does not unreasonably interfere with Operations. 

            (n)  The Manager  shall prepare or  have prepared and  submit to the
  Management Committee a  report containing a  description and  analysis of  the
  methods and costs and all  other relevant aspects of reclaiming the Properties
  pursuant  to  the  requirements of  applicable  laws,  rules  and  regulations
  governing the reclamation of  the Properties, the purpose of which shall be to
  establish a fund  to finance costs and  expense anticipated to be  incurred in
  connection with  the reclamation  or reclamation  bonding  of the  Properties.
  The Management Committee  shall determine, based upon the  reclamation report,
  the  total  cost, including  capital  budget, which  the  Management Committee
  reasonably estimates will be required  to reclaim the Properties,  including a
  schedule of the timing of the capital requirements for such purpose, and 





















                                       -26-








    32


  shall promptly establish  a reclamation fund to meet such capital requirements
  and any bonding  or financial assurance  requirements.   The reclamation  fund
  shall be funded  by contribution of  the Participants, in proportion  to their
  Participating  Interest in the  area or  areas to  which the  reclamation fund
  relates, in such amounts  and at such times as the  Management Committee shall
  determine.   The amounts determined  by the Management  Committee for Purposes
  of funding the reclamation fund  shall be included in the applicable  Programs
  and Budgets  for the  related periods.   Any unused  portion of a  reclamation
  fund   remaining  after  reclamation  of  the  area  or  areas  to  which  the
  reclamation fund relates  shall be distributed to the Participants in the same
  proportion  as  their  respective  contributions   to  the  reclamation  fund;
  provided, however,  that a Participant's  right to such  distribution, if any,
  shall  only apply so long as  the Participant retains a Participating Interest
  in the area or areas to which the reclamation fund relates.

            (o)  The Manager may  conduct environmental audits or  reviews on an
  annual or as needed basis, and the  cost and expense of such audits or reviews
  shall be charged to  the joint account and shall be  borne by the Participants
  proportionately  based on  their  Participating Interest  at  the time  of the
  audit or review.

            (p)  The Manager  shall undertake  all  other activities  reasonably
  necessary to fulfill the foregoing.

       The  Manager shall not be  in default of any  duty under this Section 8.2
  if its  failure  to perform  results  from  the failure  of  the  non-managing
  Participant to perform  acts or to contribute  amounts required of it  by this
  Agreement.

       8.3  STANDARD OF CARE.   The  Manager shall conduct  all Operations in  a
  good, workmanlike  and efficient manner,  in accordance with  sound mining and
  other applicable industry  standards and practices, and in accordance with the
  terms and provisions of leases, 


















                                       -27-









    33


  subleases,  licenses,  permits,  plans  of   operation,  contracts  and  other
  agreements pertaining  to Assets.   The  Manager shall  not be  liable to  the
  non-managing Participant for any act  or omission resulting in damage  or loss
  to  the  Venture except  to  the  extent  caused  by or  attributable  to  the
  Manager's wilful misconduct or gross negligence.

       8.4  RESIGNATION; DEEMED OFFER TO RESIGN.  The Manager may resign  upon 3
  months'  prior  notice to  the  other  Participant, in  which  case  the other
  Participant may elect to  become the  new Manager by  notice to the  resigning
  Participant within 30  days after the  notice of resignation.   If any  of the
  following shall occur, the  Manager shall be deemed to have offered to resign,
  which offer shall be accepted  by the other Participant, if at  all, within 90
  days following such deemed offer:

            (a)  The Participating Interest  of the Manager with  respect to any
  Exploration Area  or  Production  Area  becomes  less  than  that  of  another
  Participant; or

            (b)  The Manager  fails  to perform  or  in  good faith  commence  a
  material obligation  imposed upon it under  this Agreement and  action to cure
  said failure  is not  initiated within  60 days  after notice  from the  other
  Participant demanding performance; or

            (c)  The  Manager fails to  pay or  contest in good  faith its bills
  within 60 days after they are due; or

            (d)  A   receiver,   liquidator,   assignee,   custodian,   trustee,
  sequestrator  or  similar official  for a  substantial part  of its  assets is
  appointed  and such  appointment is  neither  made ineffective  nor discharged
  within 60 days after the making thereof, or such appointment is consented  to,
  requested by, or acquiesced in by the Manager; or

            (e)  The Manager  commences a  voluntary case  under any  applicable
  bankruptcy, insolvency or similar law now or hereafter in  effect; or consents
  to the entry of an 
















                                       -28-








    34


  order  for  relief in  an  involuntary  case under  any  such  law or  to  the
  appointment  of or  taking  possession by  a  receiver, liquidator,  assignee,
  custodian, trustee,  sequestrator or other similar official of any substantial
  part of  its  assets;  or  makes  a general  assignment  for  the  benefit  of
  creditors;  or fails  generally to  pay its  or  Venture debts  as such  debts
  become  due; or takes corporate  or other action in furtherance  of any of the
  foregoing; or

            (f)  Entry is  made against  the Manager  of a  judgment, decree  or
  order for  relief affecting a  substantial part  of its assets  by a  court of
  competent jurisdiction  in an involuntary case  commenced under any applicable
  bankruptcy,  insolvency  or other  similar  law  of  any  jurisdiction now  or
  hereafter in effect.

       8.5  PAYMENTS  TO MANAGER.    The Manager  shall  be compensated  for its
  services  and  reimbursed for  its  costs  hereunder  in  accordance with  the
  Accounting Procedure.

       8.6  TRANSACTIONS WITH AFFILIATES.  If the Manager  engages Affiliates to
  provide  services hereunder, it shall do so  on terms no less favorable to the
  Venture than would be the case in arm's-length transactions.

       8.7  REVIEW OF  ACCOUNTING PROCEDURE.   It is the  intent of the  Manager
  and the Participants that  the Manager shall not lose  or profit by reason  of
  its  duties  and  responsibilities  as  Manager.    The  Accounting  Procedure
  attached as Exhibit B  shall be reviewed by the Management  Committee upon the
  request  of the  Manager  or  any  Participant  to  assure  that  the  Manager
  (directly or  through its Affiliates) does not make  a profit or suffer a loss
  from  serving  as Manager.   The  Management Committee  shall, in  good faith,
  endeavor  to agree  on  modifications to  the  Accounting Procedure  that will
  remedy any alleged unfairness or inequity.

                               PROGRAMS AND BUDGETS

       9.1  OPERATIONS  PURSUANT TO  PROGRAMS  AND  BUDGETS.   Unless  otherwise
  provided herein, Operations shall  be conducted,  expenses shall be  incurred,
  and Assets shall be acquired only pursuant to adopted Programs and Budgets.

       9.2  TYPES OF  PROGRAMS.      Four  general  types  of  Programs  may  be
  proposed:   Maintenance Programs,  Exploration Programs,  Development Programs
  and Mining Programs.

            (a)  A  "Maintenance  Program"  shall  be   a  program  designed  to
  maintain  the  Joint Property  until  such  time  as  an Exploration  Program,
  Development Program or Mining Program may be proposed and adopted.

            (b)  An "Exploration  Program" shall be  a Program conducted  within
  an Exploration Area, and  it shall  include but not  be limited to  geological
  mapping, geochemical  sampling, geophysical surveys,  drilling and other  such
  work expended to ascertain the  existence, location, quantity, and  quality of
  deposits of Products on the Properties.

            (c)  A  "Development Program" shall be  a Program conducted within a
  Production  Area  that shall  include  but not  be limited  to  drilling, test
  mining,  preparing any  Feasibility Study other  than the  Initial Feasibility
  Study, and other  such work  in preparation for  the removal  and recovery  of
  Products on the Properties, but  does not encompass, by  itself, construction,
  operation, maintenance, and attendant activities  designed to bring a  Mine on
  any of the Properties into production in reasonable commercial quantities.

            (d)  A  "Mining  Program" shall  be  a  Program conducted  within  a
  Production  Area  that  is  designed  to  bring  a  Mine  into  production  in
  reasonable  commercial  quantities,  and  that  provides  for  its  subsequent
  operation.  It shall include but not be limited to engineering and 














                                       -30-








    36


  design work, and work expended toward development  of deposits of Products, as
  well as  construction, operation, maintenance,  mine expansions and  attendant
  activities.

       9.3  PREPARATION, PRESENTATION AND CONTENT OF PROGRAMS AND BUDGETS. 

            (a)  CONTENT OF PROGRAMS.   Proposed Programs  and Budgets shall  be
  prepared by the Manager.  Each  Program shall be accompanied by and  include a
  corresponding  Budget  and  shall  designate  precisely   the  area  on  which
  Operations are  to be performed, describe work to  be performed, and state the
  estimated period  of time required  to perform the  work.  Each Program  shall
  state whether  it is  an Exploration  Program, Development  Program or  Mining
  Program.   Each Development or  Mining Program shall  designate the Production
  Area to which it relates. 

            (b)  CONTENT   OF  BUDGETS.    Each  Budget  shall  be  prepared  in
  reasonable detail and shall set forth each expenditure  of $20,000 or more for
  a budgeted  item which, under  generally accepted accounting treatment,  would
  be  capitalized.   Each  Budget  for an  Exploration  Program, as  near  as is
  practicable, shall  show the estimated expenditures  for each calendar quarter
  covered by  the Budget  period.   Each Budget  for any  Development or  Mining
  Program, as near as is  practicable, shall show the estimated expenditures for
  each month covered by the Budget period.

            (c)  INITIAL  PROGRAM AND  BUDGET.    Any  other provision  of  this
  Agreement notwithstanding,  Santa Fe  shall have  no obligation  to propose  a
  Program and Budget other  than for a Maintenance Program.  The initial Program
  and Budget proposed  following contribution of the Mineral Properties shall be
  (i) supplied by  the Manager; (ii) based  upon the Initial Feasibility  Study;
  (iii) propose a Development and Mining Program for the Production Area 




















                                       -31-







    37


  specified therein; (iv)  commenced on the  effective date  of this  Agreement,
  and (v) incorporated herewith as Exhibit E.

            (d)  DURATION.  A Maintenance Program  need not be for  any specific
  duration but shall not exceed  a period of six years.  An  Exploration Program
  and  Budget is  anticipated  to be  for  a period  of  one calendar  year.   A
  Development  or Mining  Program and  Budget  is anticipated  to  extend for  a
  period of  at least  one year, but  may extend  for such  longer period as  is
  reasonably necessary to  complete the  Program.  It  is anticipated that  only
  one  Program  will  be  carried out  at  a  time  within  each Exploration  or
  Production Area.

            (e)  REVIEW.    Each  adopted  Program  and  Budget,  regardless  of
  length, shall  be reviewed at least  once a year  at a regular  meeting of the
  Management Committee.    During the  period  encompassed  by any  Program  and
  Budget, and at least 2 months prior to its expiration, a proposed Program  and
  Budget  for  the  succeeding  period shall  be  prepared  by  the  Manager and
  submitted to the Participants.

       9.4  DEFINITION OF  AREAS.    There are  two  types  of Areas:  a  single
  Exploration Area and one or more Production Area.   The Exploration Area shall
  consist  of all  of  the  Properties  that  have  not  been  designated  as  a
  Production Area.   A Production Area shall  be that portion of  the Properties
  designated in  a  Feasibility Study and other portions of  the Properties that
  may be  so designated by either a Development Program or  a Mining Program.  A
  Production Area shall  be segregated from the Exploration Area for Development
  or Mining, and  shall not encompass an area greater in size than is reasonably
  necessary to carry  out the Program.   Upon designation of a  Production Area,
  the Manager will allocate costs and personal property to the Area pursuant  to
  Section 6.2 within three months.  Also, such  Area shall thereafter be treated
  separately  as to  reports,  accounting,  expense records,  and  Participating
  Interests; it shall be subject to this 



















                                       -32-







    38


  Agreement as  a separate unit  for accounting, operating,  and other purposes.
  No more than  one Program may be  adopted and concurrently carried out  by the
  Management Committee for all or any part of a designated Production Area.

       9.5  SUBMITTAL AND APPROVAL OF PROPOSED PROGRAMS AND BUDGETS.

            (a)  PREPARATION AND SUBMITTAL OF MANAGER'S PROGRAM AND BUDGET.   At
  least  two months  prior to  implementation of  a Program and  Budget, Manager
  shall  prepare and  submit  a proposed  Program and  Budget to  the Management
  Committee.  Within thirty  days after Manager  submits a proposed Program  and
  Budget to the Management Committee, the non-managing  Participant shall submit
  to the Management Committee:

                 (i)  Notice that  the non-managing Participant  approves of the
       Program and Budget; or

                 (ii) Proposed  modifications  of   the  proposed  Program   and
       Budget, which  shall include detailed  specific objections regarding  the
       proposed Program and Budget.
  If a non-managing Participant fails to give either of the  foregoing responses
  within the  allotted time, the  failure shall be  deemed a disapproval by  the
  non-managing Participant of the Manager's proposed  Program and Budget.  If  a
  non-managing  Participant  makes   a  timely  submission  to   the  Management
  Committee pursuant to Section 9.5(a)(ii), then  the Management Committee shall
  within the following 30  days meet to consider the proposed Program and Budget
  and proposed modifications.  At  that meeting, the Management  Committee shall
  seek to develop  a Program and Budget acceptable to both the Participants.  In
  the event of a deadlock, the Manager shall make  the final determination as to
  the Program and Budget.

            (b)  FEASIBILITY  STUDY.    Any  Participant   may  propose  to  the
  Management Committee at any time that a Feasibility Study, in addition to  the
  Initial Feasibility Study, 


















                                       -33-






    39


  evaluate the feasibility of  opening or expanding a mine on  a particular area
  of  the Properties be conducted on  behalf of the Venture.   If the Management
  Committee does not approve of the preparation  of such Feasibility Study, then
  the  Participant proposing it may cause  such Feasibility Study to be prepared
  at its sole expense.  Promptly  upon completion of the Feasibility Study,  the
  Participant preparing  it shall  present it  to the  Management Committee  for
  evaluation.  If  a Separate Mining Program,  as defined in Section  9.5(c), or
  Mining Program is then adopted, based primarily  on the Feasibility Study, any
  Participant that did not contribute to the costs  of preparing the Feasibility
  Study,  shall either  reimburse the Participant  who prepared  the Feasibility
  Study in proportion to the  Participating Interest in the  relevant Production
  Area of  the non-preparing Participant  plus an additional  penalty of fifteen
  percent (15%) of  the amount of  such reimbursement, or  be diluted in  a like
  amount in accordance with Section 6.3(b).

            (c)  SEPARATE MINING  PROGRAM.   After completion  of a  Feasibility
  Study, if  the Manager  does not  propose a  Mining Program  for the  relevant
  Production Area upon the expiration of the current Program, or if the  Manager
  proposes a  Mining Program but  it is  not adopted  in the first  vote by  the
  Management Committee on  such proposal, then the non-managing  Participant may
  propose a  Mining Program for  the relevant Production Area,  to be considered
  by the  Participants in accordance  with the  procedures set forth  in Section
  9.5(a).  If  that Mining Program is  not adopted by the  Management Committee,
  then  the  non-managing  Participant  may  elect  by  written  notice  to  the
  Management Committee  to  conduct its  Mining  Program  as a  Separate  Mining
  Program.   The other  Participants (including  the Manager)  shall then  elect
  whether to contribute  to the Separate  Mining Program in accordance  with the
  procedure set  forth  in  Section  9.6,  and  their  respective  Participating
  Interests in  the relevant Production  Area shall be  calculated in accordance
  with Section 6.3.

    40


            (d)  REVISION   OF   INITIAL   PROGRAM   AND   BUDGET.     Following
  commencement of the  Initial Program and  Budget associated  with the  Initial
  Feasibility Study, Santa  Fe may revise such  Initial Program and Budget.   If
  the  revision would  increase  the capital  expenditures  contemplated in  the
  Initial Feasibility Study by more than  25%, the revision shall be treated  as
  a  proposal requiring  a  unanimous decision  of  the Management  Committee as
  provided  in Section 7.2(b)(vii).  If the  revision would increase the capital
  expenditures contemplated in  the Initial Feasibility  Study by  25% or  less,
  Hecla may elect to participate  in the additional capital expenditures, or  to
  participate only to the extent of its participation as originally  elected for
  the Initial Program and Budget (in which case it  shall be subject to dilution
  based  upon  its   election  not  to  contribute  to  the  additional  capital
  expenditures under the revision).

       9.6  ELECTION TO PARTICIPATE.

            (a)  DEADLINE  FOR ELECTION.  By  notice to the Management Committee
  within 20 days after the adoption of  a Program and Budget, a Participant  may
  elect to contribute to such Program and Budget in some  lesser amount than its
  Participating Interest in the relevant Area,  or not to contribute at all,  in
  which  cases  its  Participating  Interest  in  the  relevant  area  shall  be
  recalculated as provided in Section 6.3.  If a Participant fails to  make such
  an  election within  the  20 days,  the Participant  shall  be deemed  to have
  elected  not to contribute  to such  Program and  Budget in proportion  to its
  Participating Interest in the relevant Area as of  the beginning of the period
  covered by the Program and Budget.  

            (b)  CONTRIBUTIONS  SCHEDULE.    Contributions  for  an  Exploration
  Program shall be made at the beginning of each  calendar quarter of the Budget
  period.  Contributions  for a Development or  Mining Program shall be  made at
  the beginning of each month of the Budget 



















                                       -35-






    41


  period.    An  election to  contribute  to a  Program  may not  be  changed or
  modified  as to  a Participant's percentage contribution  during the course of
  the Program.

       9.7  SUBSEQUENT PROGRAMS.  A subsequent  Program relating to an  Area for
  which a prior  Program has been adopted  under the provisions of  this Article
  IX may be  proposed and conducted pursuant  to this Agreement.   A Participant
  may participate  in any subsequent Program  at the level of  the Participant's
  Participating Interest  in that  Area unless  the Participant's  Participating
  Interest  has been  converted to  a Net  Smelter Returns  Interest pursuant to
  Section 6.5.

       9.8  BUDGET OVERRUNS;  PROGRAM CHANGES.   The  Manager shall  immediately
  notify the  Management Committee  of any  material departure  from an  adopted
  Program and Budget.   If the  Manager exceeds an  adopted Budget by more  than
  15%, then  the  excess  over  15%,  unless directly  caused  by  an  emergency
  expenditure made  pursuant  to Section  9.9  or unless  otherwise  unanimously
  authorized by  the Management Committee, shall be for  the sole account of the
  Manager and  such excess  shall not  be included  in the  calculations of  the
  Participating  Interests.  Budget  overruns of 15% or  less shall  be borne by
  the Participants in proportion to their respective  Participating Interests in
  the affected Area as of the time the overrun occurs.

       9.9  EMERGENCY EXPENDITURES.   In case of emergency, the Manager may take
  any reasonable  action it deems necessary  to protect life, limb  or property,
  to protect the  Assets or to  comply with law  or government regulation.   The
  Manager shall promptly  notify the Participants of  the emergency expenditure,
  and  the   Manager  shall  be  reimbursed  for  all  resulting  costs  by  the
  Participants in proportion to their respective  Participating Interests in the
  affected Area at the time the emergency expenditures are incurred.

    42


       9.10 INTERIM PROGRAM AND  BUDGET.  If  the Management  Committee for  any
  reason has failed  to have adopted a Program and Budget to succeed an expiring
  or completed prior Program and  Budget, the Manager shall  continue operations
  at  levels necessary to  maintain the  Assets and to  comply with  any and all
  legal obligations of the Venture.

       9.11 EXPENDITURES  FOLLOWING  DESIGNATION  OF   SECOND  PRODUCTION  AREA.
  Notwithstanding  any other provision of  this Agreement, after the designation
  of a  second Production  Area,  Santa Fe  shall pay  the first  $3,000,000  of
  Hecla's obligations  hereunder  for  any  Program  and  Budget  covering  such
  Production Area.  Santa Fe shall  be entitled to recoup the entire  $3,000,000
  from Hecla's share of any proceeds from Products from such Production Area.


                                     ARTICLE X

                             ACCOUNTS AND SETTLEMENTS
   
       10.1 MONTHLY  STATEMENTS.    The Manager  shall  promptly  submit  to the
  Management Committee monthly  statements of accounts reflecting  in reasonable
  detail  the charges  and  credits to  the Joint  Account during  the preceding
  month.

       10.2 CASH CALLS.  On  the basis  of the adopted  Program and Budget,  the
  Manager may submit  to each Participant prior to the last day of each month, a
  billing for estimated  cash requirements for the  next month.  Within  10 days
  after receipt of  each billing, each Participant shall  advance to the Manager
  its  proportionate share of the estimated  amount.  Time is  of the essence of
  payment of such billings.   All funds in excess of immediate cash requirements
  shall be invested in  interest-bearing accounts  in a bank  to be selected  by
  the Management Committee, for the benefit of the Joint Account.

       10.3 FAILURE TO  MEET CASH CALLS.  A Participant  that fails to meet cash
  calls  in the amount  and at the times  specified in Section 10.2  shall be in
  default, and the amounts of the 















                                       -37-






    43


  defaulted  cash call shall bear  interest from the date  due at an annual rate
  equal to 3 percentage  points over the Prime Rate, but in no  event shall said
  rate of  interest exceed  the maximum  permitted by law.   The  non-defaulting
  Participant  shall have  those  rights, remedies  and  elections specified  in
  Section 6.4.

       10.4 AUDITS.   Upon  request  made by  any  Participant within  24 months
  following the end  of any calendar year  (or, if the Management  Committee has
  adopted an accounting  period other than the  calendar year, within 24  months
  after  the end  of such  period),  the Manager  shall  order an  audit of  the
  accounting and financial records for  such calendar year (or  other accounting
  period).    All  written  exceptions  to  and  claims  upon  the  Manager  for
  discrepancies disclosed  by such audit  shall be made  not more than 3  months
  after receipt  of the  audit report.   Failure to  make any such  exception or
  claim  within the 3 month period  shall mean the audit  is correct and binding
  upon the Participants.   The audits shall be conducted by a  firm of certified
  public accountants selected by the Manager.


                                    ARTICLE XI

                             DISPOSITION OF PRODUCTION

       11.1 TAKING IN KIND.   Unless otherwise provided herein, each Participant
  hereto owning a Participating Interest shall on a  monthly basis, take in kind
  or  separately  dispose  of  its  share  of the  Products  produced  from  the
  Properties.   That share shall  be defined by  the Participant's Participating
  Interest in the  Production Area from which  the Products are produced.   Risk
  of  loss of any Products held for  each Participant's respective account shall
  be borne by  such Participant, provided  that such loss is  not caused by  the
  Manager's gross  negligence,  intentional  misconduct,  or bad  faith.    Each
  Participant  shall take possession  of such Products at  the mine  site or the
  depository where held after all processing, smelting and/or refining of the 


















                                       -38-





    44


  Products  is  completed, and  will  thereafter bear  the  responsibilities and
  costs of transportation,  security and related expenses, and shall, at its own
  expense, construct, operate and maintain any  facilities necessary to receive,
  store and dispose of its share of production.

       11.2 FAILURE TO TAKE IN KIND.  If  a Participant fails to take in kind or
  separately dispose of its share of Products as required by Section 11.1  after
  10 days notice  by the Manager, the  Manager may either charge  the delinquent
  Participant 150%  of the  cost and  expense of  storing such  Products or  the
  Manager may act as the  delinquent Participant's agent to have an  independent
  contractor  remove   the  Products   and  store   them   for  the   delinquent
  Participant's account.


                                    ARTICLE XII

                            WITHDRAWAL AND TERMINATION

       12.1 TERMINATION  BY  EXPIRATION  OR AGREEMENT.    This  Agreement  shall
  terminate as expressly provided in  this Agreement, unless earlier  terminated
  by written  agreement.   At any  time after  any consecutive  six year  period
  during  which   operations  hereunder   are  conducted   solely  pursuant   to
  Maintenance Program(s)  or Exploration Program(s),  or a combination  thereof,
  as defined under Section  9.2, Santa Fe may, at its sole election  and for any
  reason, terminate  this Agreement by providing written notice  to Hecla.  Upon
  any termination  by  written agreement  or  any  termination pursuant  to  the
  immediately preceding sentence, the parties shall, unless otherwise  agreed to
  in writing as part of a  termination agreement, retain undivided interests  in
  the Properties  located  within  each  Area  in  proportion  to  the  parties'
  Participating  Interest  in each  such  Area.   Prior  to  September 6,  2002,
  neither  Participant  shall  have the  right  unilaterally  to terminate  this
  Agreement; provided, however,  if termination results  at any  time after  the
  Effective Date pursuant  to the withdrawal  provisions of  Section 12.2,  then
  the 

















                                       -39-






    45


  withdrawing Participant  shall convey its interests  to the  other Participant
  in accordance with Section 12.2(b).


       12.2 WITHDRAWAL.

            (a)  A  Participant   may  withdraw   as  a   Participant  from   an
  Exploration or Production Area in any of  three ways.  First, a Participant at
  any time may  withdraw voluntarily by giving  notice to the other  Participant
  of the effective  date of withdrawal, which  shall be the later of  the end of
  the then current  Program and Budget for the relevant Area or at least 30 days
  after the  date  of  the  notice  ("voluntary  withdrawal").    Second,  if  a
  Participant fails  to  make  a  contribution under  Section  6.4(b)(ii),  upon
  election pursuant to  that Section, it will  be deemed to have  withdrawn from
  the relevant Area.  Third, if a Participant allows  its Participating Interest
  in an  Exploration or Production  Area to  be reduced to  less than 15%  under
  Section 6.5, then it will be deemed to have withdrawn from the relevant Area.

            (b)  Upon withdrawal  from an Exploration  or Production Area,  this
  Agreement shall  terminate  with respect  to  such  Area and  the  withdrawing
  Participant shall be deemed to  have transferred to the  remaining Participant
  its Participating  Interest in the  relevant Area,  without cost and  free and
  clear of royalties, liens or other  encumbrances arising by, through or  under
  such  withdrawing Participant, except those royalties  and other exceptions to
  title described in  Part 1 of Exhibit  A, Section 6.4(b)(ii) and  Section 6.5,
  and  those other  interests  and exceptions  to  which both  Participants have
  given  their  written  consent  after  the  date  of  this  Agreement.     The
  withdrawing Participant  shall execute and  deliver all instruments  as may be
  necessary to  effect  the  transfer  of  its  Participating  Interest  in  the
  relevant Area.   Any withdrawal under this Section  12.2 shall not relieve the
  withdrawing Participant of  its share of liabilities to third persons (whether
  such accrues before or after such withdrawal) arising out of Operations 


















                                       -40-





    46


  conducted hereunder within the  relevant Area prior  to such withdrawal.   For
  purposes of this  Section 12.2, the  withdrawing Participant's  share of  such
  liabilities shall be equal to  its Participating Interest in the relevant Area
  where  the liability  was incurred  at the  earliest time  such liability  was
  created or incurred.  

       12.3 CONTINUING  OBLIGATIONS.   On termination  of  this Agreement  under
  Section 12.1 with respect to  an Area, or with  respect to both Areas, as  the
  case may be, the Participants  shall remain liable for  continuing obligations
  hereunder  until  final  settlement   of  all   accounts.    Such   continuing
  obligations include liability for all  amounts chargeable with respect  to any
  Budget  to which  the withdrawing  Participant is  committed, including  costs
  incurred pursuant  to such Budget after  the effective date  of withdrawal but
  not in excess of the most  recent cost estimates committed to, or approved by,
  such withdrawing Participant.   The withdrawing Participant shall  also remain
  liable  for any liability arising out  of Operations conducted on the relevant
  Area or Areas  prior to the  withdrawal, whether the liability  accrues before
  or after such withdrawal from the relevant Area or Areas.

       12.4 DISPOSITION OF  ASSETS ON TERMINATION.   Promptly after  termination
  of  this  Agreement under  Section 12.1  with respect  to all  Properties, the
  Manager shall  take all  action necessary  to wind  up the  activities of  the
  Venture,  and  all   costs  and  expenses  incurred  in  connection  with  the
  termination of the Venture shall be  expenses chargeable to the Venture.   The
  Assets shall first  be paid, applied,  or distributed in  satisfaction of  all
  liabilities of  the Venture to  third parties and  then to satisfy any  debts,
  obligations, or  liabilities owed  to the  Participants.   Before distributing
  any funds  or Assets  to Participants,  the Manager  shall have  the right  to
  segregate amounts which, in the  Manager's reasonable judgment, are  necessary
  to discharge  continuing  obligations  or  to  purchase  for  the  account  of
  Participants, bonds or other securities 


















                                       -41-





    47


  for  the  performance  of  such  obligations.    The  foregoing  shall not  be
  construed to include  the repayment of any Participant's capital contributions
  or Capital  Account balance.   Thereafter, any  remaining cash  and all  other
  Assets shall be distributed  (in undivided interests unless otherwise  agreed)
  to the  Participants.   No  Participant shall  receive a  distribution of  any
  interest in Products  or proceeds from the sale  thereof if such Participant's
  Participating  Interest   therein  has  been   terminated  pursuant  to   this
  Agreement.

       12.5 TRANSFER  COVENANTS.    A Participant  that  withdraws  pursuant  to
  Section 12.2,  is a  "withdrawing Participant"  as the  term is  used in  this
  Section.  If  a withdrawing  Participant, or  the Affiliate  of a  withdrawing
  Participant,  acquires any  interest from  a third  party  within the  Area of
  Interest for  twelve (12) months after the effective  date of withdrawal, such
  withdrawing Participant or Affiliate shall be obligated  to offer to convey to
  the  non-withdrawing Participant, without cost, any  such property or interest
  so acquired.  Such  offer shall be made in writing and  can be accepted by the
  non-withdrawing Participant at any time  within 45 days after it  receives the
  offer.

       12.6 RIGHT  TO  DATA  AFTER  TERMINATION.    After  termination  of  this
  Agreement pursuant  to Section  12.1, each  Participant shall  be entitled  to
  copies of  all information  acquired hereunder  before the  effective date  of
  termination  not previously furnished  to it, but  a Participant  shall not be
  entitled to any such copies pertaining solely to an Area withdrawn from  after
  withdrawal.

       12.7 CONTINUING  AUTHORITY.    On termination  of  this  Agreement  under
  Section  12.1   with  respect  to  all  Properties  or  the  withdrawal  of  a
  Participant  pursuant to  Section  12.2 with  respect  to all  Properties, the
  Manager  shall  have the  power  and  authority,  subject to  control  of  the
  Management Committee, if any,  to do all things on behalf  of the Participants
  which are reasonably necessary or convenient  to:  (a) wind up Operations  and
  (b) complete any transaction 

















                                       -42-








    48


  and satisfy  any obligation, unfinished  or unsatisfied, at  the time of  such
  termination or  withdrawal, if  the transaction  or obligation  arises out  of
  Operations prior to  such termination or  withdrawal.  The Manager  shall have
  the power and authority to  grant or receive extensions of time or  change the
  method of  payment of an  already existing liability  or obligation, prosecute
  and defend  actions on behalf  of the Participants  and the Venture,  mortgage
  Assets, and take any  other reasonable  action in any  matter with respect  to
  which the former  Participants continue to have,  or appear or are  alleged to
  have, a common interest or a common liability.


                                   ARTICLE XIII

                                 AREA OF INTEREST
   
       13.1 GENERAL.   Any  interest or right  to acquire  any interest  in real
  property  within  the Area  of  Interest  acquired  during the  term  of  this
  Agreement by or on  behalf of a Participant or any  Affiliate shall be subject
  to the  terms and provisions of this Agreement.   Sections 13.2, 13.3 and 13.4
  of this Article  XIII shall only apply  to acquisitions from third  parties of
  any interest within the Area of Interest.

       13.2 NOTICE  TO  NONACQUIRING PARTICIPANT.    Within  30 days  after  the
  acquisition of  any interest  or the  right to  acquire any  interest in  real
  property wholly  or  partially  within  the  Area  of  Interest  (except  real
  property  acquired  by the  Manager  pursuant  to  a  Program), the  acquiring
  Participant  shall notify  the  other Participant  of  such acquisition.   The
  acquiring Participant's notice shall  describe in detail the acquisition,  the
  lands  and  minerals  covered  thereby,  the  cost  thereof,  committed   work
  expenditures  and reclamation obligations, and  the reasons  why the acquiring
  Participant  believes that  the acquisition  of  the interest  is in  the best
  interests  of the  Participants under  this Agreement.    In addition  to such
  notice,   the   acquiring  Participant   shall   provide   the   non-acquiring
  Participants with copies of all instruments documenting the 

















                                       -43-







    49


  acquisition,  and shall  keep  any and  all  other information  concerning the
  acquired interest available for inspection by the other Participant.

       13.3 OPTION EXERCISED.   If, within 30 days after receiving the acquiring
  Participant's   notice,   the   other  Participant   notifies   the  acquiring
  Participant of  its  election  to  accept  a  proportionate  interest  in  the
  acquired interest  equal to its  Participating Interest in  the Exploration or
  Production Area of which the acquired interest would be a part, the  acquiring
  Participant shall convey  to the other Participant, by appropriate conveyance,
  such a proportionate  undivided interest therein.  The acquired interest shall
  become  a  part   of  the  Properties  for  all  purposes  of  this  Agreement
  immediately upon the  notice of such  other Participant's  election to  accept
  the proportionate  interest therein.   Such other  Participant shall  promptly
  pay  to the  acquiring  Participant its  proportionate  share of  the latter's
  actual out-of-pocket acquisition costs.

       13.4 OPTION  NOT EXERCISED.  If the other  Participant does not give such
  notice  within the 30 day period  set forth in Section 13.3,  it shall have no
  interest in the  acquired interest, and the  acquired interest shall not  be a
  part of the Properties or be subject to this Agreement.

       13.5 LANDS OWNED OR CONTROLLED BY HECLA WITHIN THE AREA OF INTEREST.

            (a)  Certain lands that are currently  owned and controlled by Hecla
  within the  Area  of Interest  are excluded  from Hecla's  Properties for  the
  purposes of  this Agreement.  The excluded lands  are identified on Exhibit A.
  Santa  Fe   may,  at  its  sole  election  and  without  further  exchange  of
  consideration, subject the  excluded lands, or any  part or parts  thereof, to
  this Agreement by providing written notice(s) of its election to Hecla.   Such
  notice(s) shall specify  the excluded lands, or  parts thereof, for which  the
  election  is  made.    Effective  upon  receipt  of  Santa  Fe's  notice,  the
  properties specified  in such notice  shall become  a part of  the Properties,
  and  Hecla  shall,   without  further  exchange  of   consideration,  execute,
  acknowledge 














                                       -44-








    50


  and deliver a good and sufficient deed or assignment of an undivided  interest
  in  the formerly excluded lands equal  to Santa Fe's Participating Interest in
  all Assets at the time the election is made.

            (b)   Santa  Fe's election(s)  to  subject  excluded lands  to  this
  Agreement under this Section 13.5 may be  made at any time commencing with the
  Effective  Date  and continuing  through  the  earlier of  21  years from  the
  Effective Date or one year after Hecla hereafter  notifies Santa Fe in writing
  that all  of the excluded lands (which  remain excluded as of  the time of the
  notice)  have  become unencumbered  by permitting  or bonding  requirements or
  environmental or reclamation  obligations owing to any local, state or federal
  agency  and  are  no  longer  the  subject   of  any  existing  or  threatened
  governmental  investigation or  enforcement proceeding  or  public or  private
  litigation.  Upon  the expiration of  such election period, Hecla  may dispose
  of any portion of the excluded lands for which an election has not  been made.


            (c)  Santa Fe's election rights identified in  this Section 13.5 are
  not limited to a single  election, but may be  exercised from time to time  on
  various portions of the excluded lands.

            (d)   Notwithstanding  any other  provision of  this  Agreement, all
  fixtures and  facilities located on  the surface of  either Hecla's Properties
  or  the excluded lands are and shall remain  the sole and separate property of
  Hecla,  and  no election  by  Santa Fe  respecting Hecla's  Properties  or the
  excluded lands shall create  any current or future property right  in Santa Fe
  to such fixtures  and facilities; provided, however,  Santa Fe may  include in
  any election under this Section  such mineral-bearing materials located  at or
  in Hecla's surface facilities as Santa Fe may  specify in making the election.
  Santa Fe agrees  to cooperate with Hecla  to ensure Hecla  has full access  to
  such fixtures and facilities  for any purposes including, but  not limited to,
  the 


















                                       -45-









    51


  dismantling,   salvaging,   closure,  restoration,   remediation,  monitoring,
  maintenance or sale of all or part of such fixtures and facilities.


                                    ARTICLE XIV

                      ABANDONMENT AND SURRENDER OF PROPERTIES

       14.1 SURRENDER OR ABANDONMENT OF PROPERTY.  The  Management Committee may
  authorize the Manager to  surrender or abandon part or all  of the Properties.
  If the Management  Committee authorizes any such surrender or abandonment over
  the objection  of a  Participant, the Participant  that desires to  abandon or
  surrender  shall  transfer  to  the   objecting  Participant,  by  appropriate
  conveyance and  without  cost to  the  surrendering  Participant, all  of  the
  surrendering  Participant's  interest  in  the  property  to  be abandoned  or
  surrendered, and the abandoned or surrendered property  shall cease to be part
  of the Properties.   If Properties to be abandoned or surrendered are included
  in a  mining lease or  sublease, abandonment shall be  conducted in accordance
  with and  only to  the extent  permitted by  any appurtenant  mining lease  or
  sublease.    Any  Transfer under  this  Section  14.1  shall  not relieve  the
  transferring Participant of  its share of liabilities to third persons arising
  out of  Operations conducted  prior to such  Transfer.   Any assignment of  an
  interest  pursuant  to  this  Section 14.1  shall  not  reduce  or change  the
  transferor's Participating Interest.

       14.2 REACQUISITION.   If  any  Properties  are abandoned  or  surrendered
  under  the provisions  of this  Article XIV,  then, unless  this Agreement  is
  earlier  terminated,  neither  Participant nor  any  Affiliate  thereof  shall
  acquire any interest in  such Properties or a right to acquire such Properties
  for a period of  2 years following the date of  such abandonment or surrender.
  If a Participant  reacquires any Properties in violation of this Section 14.2,
  the  other Participant  may  elect by  notice  to the  reacquiring Participant
  within 45 days after it has actual 

















                                       -46-









    52


  notice of  such reacquisition,  to have  such properties  made subject to  the
  terms  of  this Agreement.    In  the event  such  an  election  is made,  the
  reacquired  properties  shall thereafter  be  treated as  Properties,  and the
  costs of  reacquisition shall be  borne solely by  the reacquiring Participant
  and shall  not  be included  for  purposes  of calculating  the  Participants'
  respective Participating Interests.   


                                    ARTICLE XV

                               TRANSFER OF INTEREST
   
       15.1 GENERAL.   Subject  to  the  terms  of  any  appurtenant  leases  or
  subleases, a Participant shall have the  right to Transfer to any third  party
  all or  any part of  its interest in  or to this  Agreement, its Participating
  Interest  in  an Exploration  or  Production  Area  or the  Assets  solely  as
  provided in this Article XV.

       15.2 LIMITATIONS ON  FREE  TRANSFERABILITY.    The Transfer  right  of  a
  Participant  in  Section 15.1  shall  be subject  to  the following  terms and
  conditions:

            (a)  No  transferee  of  all  or  any  part of  the  interest  of  a
  Participant in this Agreement,  any Participating  Interest in an  Exploration
  or  Production Area  or the  Assets shall  have  the rights  of a  Participant
  unless and  until  the transferring  Participant  has  provided to  the  other
  Participant  notice  of the  Transfer,  and  except  as  provided in  Sections
  15.2(g)  and  15.2(h),  the  transferee,  as of  the  effective  date  of  the
  Transfer, has committed in writing  to be bound by this Agreement to  the same
  extent as the transferring Participant;

            (b)  No Transfer  permitted  by this  Article XV  shall relieve  the
  transferring  Participant  of its  share  of any  liability,  whether accruing
  before or after such Transfer, which arises out of  Operations conducted prior
  to such Transfer;
















                                       -47-








    53


            (c)  The transferring Participant and the  transferee shall bear all
  tax consequences of the Transfer;

            (d)  In the event of a Transfer of less than all of a  Participating
  Interest in an  Area, the transferring  Participant and  its transferee  shall
  act and be treated as one Participant with respect to such Area;

            (e)  No Participant  shall Transfer any  interest in this  Agreement
  or the Assets except by Transfer of part or  all of its Participating Interest
  in the Exploration or a Production Area, or both; 

            (f)  If the  Transfer  is  the  grant  of  a  security  interest  by
  mortgage, deed of trust, pledge, lien or other encumbrance of any interest  in
  this Agreement, any Participating Interest in an Area  or the Assets to secure
  a loan or  other indebtedness  of a Participant  in a  bona fide  transaction,
  such security  interest shall be  subordinate to the  terms of  this Agreement
  and the  rights and interests  of the other  Participant hereunder.  Upon  any
  foreclosure or  other  enforcement of  rights  in  the security  interest  the
  acquiring  third party shall  be deemed  to have  assumed the position  of the
  encumbering  Participant  with  respect  to  this  Agreement  and  the   other
  Participant,  and it  shall  comply  with  and  be  bound  by  the  terms  and
  conditions of this Agreement;

            (g)  If a sale  or other commitment  or disposition  of Products  or
  proceeds from the  sale of Products by  a Participant upon distribution  to it
  pursuant  to Article  XI  creates in  a  third party  a  security interest  in
  Products  or  proceeds  therefrom prior  to  such  distribution,  such  sales,
  commitment or  disposition shall  be subject  to the terms  and conditions  of
  this Agreement;

            (h)  Only United  States currency  shall be used  for Transfers  for
  consideration; and

    54


            (i)  Regardless of the  number of  Transfers, the total  Net Smelter
  Returns interest available to  be divided among all  non-Participants pursuant
  to Section  6.4(b)(ii) or 6.5 hereof shall not  exceed the Net Smelter Returns
  interest percentage determined under  Section 6.4(b)(ii) or 6.5 at the time of
  its creation.

       15.3 PREEMPTIVE RIGHT.   Except as otherwise provided in Section 15.4, if
  a Participant  desires to Transfer  all or  any part of  its interest in  this
  Agreement,  any  Participating  Interest  in  an  Area  or  Areas,  the  other
  Participant  shall  have a  preemptive  right  to  acquire  such interests  as
  provided in this Section 15.3.

            (a)  A  Participant desiring  to  Transfer all  or  any part  of its
  interest in this Agreement or its  Participating Interest in an Area or  Areas
  or the Assets shall first offer such  interest to the other Participant.   The
  offer shall state  the price and all  other pertinent terms and  conditions of
  the desired  Transfer.  The other Participant shall have 60 days from the date
  such offer  is delivered  to notify  the transferring  Participant whether  it
  elects  to acquire  the offered  interest at  the price  and on  the terms and
  conditions set forth  in the offer.  If  it does so elect, the  Transfer shall
  be consummated  promptly after  notice of such  election is  delivered to  the
  transferring Participant.

            (b)  If the  other Participant fails  to so elect  within the period
  provided for in Section 15.3(a),  the transferring Participant shall  have 120
  days following  the  expiration  of  such  period  to  market  and  ultimately
  consummate a Transfer  at a price  and on terms no  less favorable than  those
  offered by  the  transferring Participant  to  the  other Participant  in  the
  notice required in Section 15.3(a).

            (c)  If the transferring Participant fails  to consummate a Transfer
  within the period  set forth in Section  15.3(b), the preemptive right  of the
  other Participant in such offered 



















                                       -49-








    55


  interest shall be  deemed to be revived.   Any subsequent efforts  to Transfer
  such interest shall be conducted in accordance with  all of the procedures set
  forth in this Section 15.3.

       15.4 EXCEPTIONS TO PREEMPTIVE  RIGHT.  Section  15.3 shall  not apply  to
  the following:

            (a)  Transfer  by  a  Participant  of   all  or  any  part   of  its
  Participating Interest to an  Affiliate of Hecla or Santa Fe, provided that if
  the transferee ceases to  be an Affiliate of  Hecla or Santa  Fe, it shall  be
  required  to  offer  to  sell   such  Participating  Interest  to   the  other
  Participant in  accordance with  Section 15.3  at a  price equal  to the  fair
  market value  of such Participating  Interest as determined  by an independent
  appraiser agreed to by the Participants;

            (b)  Incorporation  of   a   Participant,   or   corporate   merger,

  surviving entity shall possess substantially all  of the stock, or all of  the
  property  rights and  interests, and  be subject  to substantially  all of the
  liabilities and obligations of that Participant;

            (c)  The grant  by  a Participant  of  a  security interest  in  any
  interest  in this  Agreement,  any Participating  Interest,  or the  Assets by
  mortgage, deed of trust, pledge, lien or other encumbrance; 

            (d)  A  sale  or  other commitment  or  disposition  of  Products or
  proceeds from  sale  of Products  by  a Participant  upon  distribution to  it
  pursuant to Article XI; or

            (e)  Transfer  of all  or  any portion  of the  capital  stock of  a
  Participant, provided  that the  Participating Interest or  Interests of  such
  Participant do not constitute more than 80%  of the total assets owned by such
  Participant.

  Agreement, its Participating Interest, or the Assets; or

            (c)  To a governmental  agency or to the public which the disclosing

  or the rules of any stock exchange.

       In any  case to which  this Section  16.2 is  applicable, the  disclosing

  making of such disclosure.   As to any disclosure pursuant  to Section 16.2(a)
  or (b), only  such confidential information as  such third party shall  have a
  legitimate business  need to  know  shall be  disclosed and  such third  party
  shall first  agree in  writing to  protect the  confidential information  from
