   The Company is making the Offer to eliminate  the potential  dilutive  effect
that would occur if the  Warrants  are  exercised  by the holders  thereof on or
before  November  30,  1995,  the  expiration  date  of the  Warrants.  Warrants
purchased pursuant to the Offer will be retired by the Company.

   The Board of Directors of the Company (the "Board") has authorized the Offer.
The Company  anticipates that it will fund the purchase of Warrants  pursuant to
the Offer and the payment of related  fees and  expenses  through an offering of
8.70% debt  securities.  In this  regard,  the  Company  has  commenced a public
offering of Senior Subordinated Notes due May 15, 2005 (the "Debt Offering") and
expects that the Debt  Offering,  if  successful,  will be completed  during the
pendency  of the  Offer.  The  Offer  is  contingent  upon  closing  of the Debt
Offering. See Section 8.

   The Company believes the Offer is fair to warrantholders.  In particular, the
Offer  gives  warrantholders  the  opportunity  to sell their  Warrants at a 17%
premium over the closing sales price of the Warrants on May 12, 1995.  The Offer
will also provide  warrantholders who are considering a sale of all or a portion
of their  Warrants the  opportunity  to sell their Warrants for cash without the
usual transaction costs associated with open market sales.

   Neither the Company nor the Board of  Directors  of the Company  received any
report,  opinion  or  appraisal  which  is  materially  related  to  the  Offer,
including, but not limited to, any such report, opinion or appraisal relating to
the  consideration  or the  fairness of the  consideration  to be offered to the
holders of the Warrants or the fairness of such  transaction  to the Company.  A
majority of the directors who are not employees of the Company have not retained
an  unaffiliated   representative  to  act  solely  on  behalf  of  unaffiliated
warrantholders for the purposes of negotiating the terms of the transaction.

   Following the  consummation of the Offer,  the business and operations of the
Company  will be continued by the Company  substantially  as they are  currently
being conducted. Except as disclosed in this Offer to Purchase, including in any
report or statement incorporated by reference herein, the Company has no present
plans or  proposals  that would result in (i) the  acquisition  by any person of
additional  securities of the Company,  or the  disposition of securities of the
Company, (ii) an extraordinary corporate transaction,  such as a material merger
or reorganization, any liquidation, or any sale or transfer of a material amount
of assets,  involving the Company or any of its material  subsidiaries  with any
other non-affiliated entity, (iii) any change in the present Board or management
of the Company,  including, but not limited to, a plan or proposal to change the
number or term of the directors, to fill any existing vacancy on the Board or to
change any material term of the  employment  contract of any executive  officer,
except in each case pursuant to actions that may be taken at the Company's  1995
Annual Meeting of  Stockholders  to be held on May 18, 1995, as  contemplated in
the Company's  Proxy  Statement  dated April 7, 1995,  incorporated by reference
herein and except for a possible increase in the size of the Board from 11 to 12
members currently under  consideration,  (iv) any material change in the present
dividend rate or policy or indebtedness or capitalization of the Company, except
for the offering by the Company of $200,000,000 of its 8.70% Senior Subordinated
Notes due May 15, 2005 being offered  concurrently  with this Offer,  a proposed
increase in its  revolving  credit  facility  from $300 to $500  million,  and a
proposed  secured  financing  of $50  million  to  facilitate  the  purchase  of
equipment to be used at the Company's Robinson mine site, (v) any other material
change in the Company's corporate structure or business,  (vi) any change in the
Company's  charter,  bylaws or  instruments  corresponding  thereto or any other
actions  which may impede  the  acquisition  or  control  of the  Company by any
person,  (vii) any class of  equity  security  of the  Company  (other  than the
Warrants) being delisted from a national securities exchange or to ceasing to be
authorized  to be quoted in an  inter-dealer  quotation  system of a  registered
national  securities  association,  (viii) any class of equity securities of the
Company  (other  than  the  Warrants)   becoming  eligible  for  termination  of
registration pursuant to Section 12(g)(4) of the Securities Exchange Act of 1934
(the " Exchange  Act"),  or (ix) the  suspension of the Company's  obligation to
file reports pursuant to Section 15(d) of the Exchange Act.

   Following  the  expiration  of the  Offer,  the  Company  may,  in  its  sole
discretion,  purchase any then outstanding Warrants through privately negotiated
transactions,  open market purchases, another tender offer or otherwise, on such
terms and at such  prices as the Company may  determine  from time to time,  the
terms of which  could  differ  from those of the Offer,  except that the Company
will not make any  such  purchases  of  Warrants  until  the  expiration  of ten
business days after the termination of the Offer.  Any possible future purchases
of Warrants by the Company  will depend on many  factors,  including  the market
price  of  the  Warrants,   the  Company's  business  and  financial   position,
alternative  investment  opportunities  available,  the results of the Offer and
general economic and market conditions.


   The  purchase  of  Warrants  pursuant  to the Offer will reduce the number of
warrantholders  and the number of Warrants that might  otherwise trade publicly,
and, depending upon the number of Warrants so purchased,  could adversely affect
the liquidity and market value of the remaining Warrants held by the public.


   Depending upon the number of Warrants  purchased  pursuant to the Offer,  the
Warrants may no longer meet the requirements of the NYSE for continued  listing.
As of May 5,  1995,  there  were  4,067,971  Warrants  issued  and  outstanding.
According to the NYSE's published guidelines,  the NYSE would consider delisting
the Warrants if, among other things, the number of publicly held Warrants should
fall  below  100,000  or if the  number of  round-lot  holders  (holders  of 100
warrants) falls below 500. If, as a result of the purchase of Warrants  pursuant
to the Offer or otherwise,  the Warrants no longer meet the  requirements of the
NYSE for continued listing and the listing of the Warrants is discontinued,  the
market for the Warrants could be adversely affected.

   In the event of the  delisting  of the  Warrants by the NYSE,  it is possible
that the Warrants would continue to trade on another  securities  exchange or in
the over-the-counter  market and that price quotations would be reported by such
exchange,  by the NASD through the National  Association  of Securities  Dealers
Automated  Quotation  System  ("NASDAQ") or by other sources.  The extent of the
public market for the Warrants and the  availability of such  quotations  would,
however,  depend upon factors such as the number of warrantholders  remaining at
such time,  the interest in  maintaining a market in the Warrants on the part of
securities  firms, the possible  termination of registration  under the Exchange
Act, as described below, and other factors.


   The Warrants are presently  "margin  securities" under the regulations of the
Board of Governors of the Federal  Reserve System,  which has the effect,  among
other things,  of allowing  brokers to extend  credit on the  collateral of such
securities.  If the Warrants remain listed on the NYSE, they will continue to be
"margin  securities."  If the Warrants  were  delisted,  depending  upon factors
similar  to those  described  above,  they  might no longer  constitute  "margin
securities" for purposes of the margin  regulations of the Board of Governors of
the Federal System,  and,  therefore,  could no longer be used as collateral for
loans made by brokers.


   The Warrants are currently registered under the Exchange Act. Registration of
the Warrants  under the Exchange Act may be terminated  upon  application of the
Company to the  Securities and Exchange  Commission  (the  "Commission")  if the
Warrants  are  neither  held by 300 or more  holders  of record  nor listed on a
national securities exchange.  Termination of registration of the Warrants under
the  Exchange  Act would  substantially  reduce the  information  required to be
furnished by the Company to holders of the Warrants (although the Company would,
among  other  things,  remain  subject to the  reporting  obligations  under the
Exchange  Act as a result of its other  outstanding  securities)  and would make
certain  provisions  of the Exchange Act no longer  applicable in respect of the
Warrants.   If  registration  of  the  Warrants  under  the  Exchange  Act  were
terminated,  the Warrants would no longer be "margin  securities" or be eligible
for NASDAQ reporting.

SECTION 2. CERTAIN FEDERAL INCOME TAX CONSEQUENCES

   Purchases of the Warrants will be taxable transactions for Federal income tax
purposes and may also be taxable  transactions  under applicable  state,  local,
foreign,  and other tax laws.  For  Federal  income tax  purposes,  a  tendering
warrantholder  will  realize  gain or loss equal to the  difference  between the
amount  of cash  received  by the  warrantholder  pursuant  to the Offer and the
warrantholder's tax basis in the Warrants transferred pursuant to the Offer.


   Generally,  the gain or loss  realized by the  warrantholder  will be capital
gain or loss pursuant to Section 1234 of the Internal Revenue Code (the "Code").
However,  the gain or loss will be ordinary in character if the stock subject to
the Warrants  would not have  qualified  as a capital  asset in the hands of the
warrantholder.  Thus, for example,  any gain or loss realized by a dealer in the
Warrants  will be ordinary  income or loss. In such a case, a dealer in warrants
to  acquire  property  is  considered  a dealer in the  property  subject to the
warrant.  Further, the gain or loss will be ordinary in character if the gain or
loss on the  transfer  of the  Warrants  is treated  as  ordinary  in  character
pursuant to a provision of the Code other than Section 1234.  Thus, for example,
any gain  realized  in  connection  with a Warrant  received  in a  compensatory
transfer  will be  ordinary  in  character.  Similarly,  any  gain  that  may be
characterized  as having been realized in connection with the  distribution of a
dividend will be ordinary in character.

   Capital gain or loss realized on a transfer of a Warrant will be long-term if
the  Warrants  were  held for more  than one  year.  In the case of any  Warrant
acquired pursuant to a nontaxable stock dividend,  the  warrantholder's  holding
period will  include the holding  period of the stock with  respect to which the
dividend was paid. 

   The recognition of losses realized on transfers of Warrants may be subject to
limitations on losses under various  provisions of the Code.  These  limitations
may apply in the case of capital as well as ordinary losses.

   Additionally,  certain  special  treatment  may be  applicable in the case of
Warrants  that are held as part of a  "straddle"  within the  meaning of Section
1092 of the Code, or as part of a "conversion transaction" within the meaning of
Section  1258(c) of the Code,  or are  otherwise  identified  in the Code as the
object of special treatment.

   In addition to Federal backup  withholding  discussed in Section 5 below, the
Depositary may, in the case of foreign warrantholders, be required to withhold a
portion of the gross proceeds otherwise payable pursuant to the Offer to satisfy
Federal income withholding tax requirements.

   THE FEDERAL  INCOME TAX  DISCUSSION  SET FORTH ABOVE IS INCLUDED  FOR GENERAL
INFORMATION  ONLY.  THE  COMPANY HAS NEITHER  OBTAINED  NOR  REQUESTED A WRITTEN
OPINION OF THE TAX ASPECTS OF THE OFFER. EACH  WARRANTHOLDER IS URGED TO CONSULT
SUCH HOLDER'S OWN TAX ADVISOR TO DETERMINE THE  PARTICULAR TAX  CONSEQUENCES  TO
SUCH HOLDER (INCLUDING THE APPLICABILITY AND EFFECT OF STATE, LOCAL, FOREIGN AND
OTHER TAX LAWS) OF THE TRANSFER OF THE WARRANTS PURSUANT TO THE OFFER.

SECTION 3. CERTAIN LEGAL MATTERS; REGULATORY AND FOREIGN APPROVALS; NO
           APPRAISAL RIGHTS


   The Company is not aware of any license or regulatory  permit that appears to
be material to its business that might be adversely  affected by its acquisition
of Warrants as  contemplated  in the Offer or of any approval or other action by
any  government  or  governmental,  administrative  or  regulatory  authority or
agency,   domestic  or  foreign,  that  would  be  required  for  the  Company's
acquisition of Warrants pursuant to the Offer. Should any such approval or other
action be required,  the Company  currently  contemplates that it will seek such
approval or other action.  The Company cannot  predict  whether it may determine
that it is required  to delay the  acceptance  for  payment of, or payment  for,
Warrants  tendered pursuant to the Offer pending the outcome of any such matter.
There can be no assurance  that any such  approval or other  action,  if needed,
would be obtained or would be obtained  without  substantial  conditions or that
the  failure to obtain any such  approval  or other  action  might not result in
adverse  consequences  to the  Company's  business.  In  lieu  of  seeking  such
approval,  the Company may  determine  to  terminate  the Offer as  described in
Section 8. The Company  intends to make all required  filings under the Exchange
Act. The Company's  obligations  under the Offer to accept for payment,  or make
payment for, Warrants is subject to certain conditions. See Section 8.


   There is no stockholder or warrantholder vote required in connection with the
Offer.

   There are no appraisal  rights available to holders of Warrants in connection
with the Offer.

                                  THE OFFER

SECTION 4. EXPIRATION DATE; EXTENSION OF THE OFFER.


   Upon the terms and subject to the  conditions of the Offer,  the Company will
accept for payment (and thereby purchase) any and all Warrants that are properly
tendered on or before the Expiration  Date (and not withdrawn in accordance with
Section  6) at the  Purchase  Price.  The term  "Expiration  Date"  means  12:00
midnight,  Eastern  Time,  on  Wednesday,  June 14,  1995,  unless and until the
Company  shall have  extended the period of time during which the Offer is open,
in which  event the term  "Expiration  Date"  shall refer to the latest time and
date at which the Offer,  as so  extended  by the  Company,  shall  expire.  See
Section 13 for a description  of the  Company's  right to extend the time during
which the Offer is open and to delay,  terminate  or amend the  Offer.  See also
Section 8 regarding certain conditions of the Offer.


   As described in Section 13, the Company expressly  reserves the right, in its
sole discretion,  at any time or from time to time, to extend the period of time
during  which  the  Offer  is open by  giving  oral or  written  notice  of such
extension to the  Depositary  and by making  public  announcement  thereof.  See
Section 13. There can be no assurance,  however,  that the Company will exercise
its right to extend the Offer.

   If the Company  increases  the price to be paid for Warrants and the Offer is
scheduled  to expire at any time  earlier  than the tenth  business day from and
including  the date that  notice of such  increase is first  published,  sent or
given in the manner  specified  in Section 13, the Offer will be extended  until
the expiration of the ten business day period immediately  following the date of
such notice. The Company has agreed not to decrease the price to be paid for the
Warrants,  decrease the number of Warrants  subject to the Offer,  or change the
consideration  therefor from cash to non-cash  instruments.  For purposes of the
Offer,  "business  day" means any day other than a  Saturday,  Sunday or Federal
holiday and consists of the time period from 12:01 a.m.  through 12:00 midnight,
Eastern Time.


   All  Warrants  purchased  pursuant  to the  Offer  will be  purchased  at the
Purchase  Price in cash,  upon the terms and subject to the conditions set forth
in this Offer to Purchase.  All Warrants  not  purchased  pursuant to the Offer,
including  Warrants  tendered and  withdrawn,  will be promptly  returned to the
tendering warrantholders at the Company's expense.


SECTION 5. PROCEDURE FOR TENDERING OF WARRANTS

         PROPER  TENDER  OF  WARRANTS.  For  Warrants  to be  properly  tendered
      pursuant to the Offer:  

         (a) the Warrants (or confirmation of receipt of such Warrants  pursuant
      to the procedures for book-entry transfer set forth below),  together with
      a  properly  completed  and duly  executed  Letter  of  Transmittal  (or a
      facsimile thereof) with any required signature  guarantees (or in the case
      of book- entry transfer,  an Agent's Message (as defined below)),  and any
      other documents  required by the Letter of  Transmittal,  must be received
      before the  Expiration  Date by the Depositary at one of its addresses set
      forth on the back cover of this Offer to Purchase; or

         (b)  the  tendering  warrantholder  must  comply  with  the  guaranteed
      delivery procedure set forth below.


   A tender of Warrants made pursuant to any method of delivery set forth herein
will constitute a binding agreement between the tendering  warrantholder and the
Company upon the terms and conditions of the Offer.

   SIGNATURE  GUARANTEES  AND METHOD OF  DELIVERY.  No  signature  guarantee  is
required on the Letter of  Transmittal if the Letter of Transmittal is signed by
the registered  owner of the Warrants (which term, for purposes of this Section,
includes any participant in The Depository Trust Company, the Midwest Securities
Trust Company or the Philadelphia  Depository Trust Company  (collectively,  the
"Book-Entry  Transfer  Facilities")  whose name  appears on a security  position
listing  as the owner of the  Warrants)  tendered  therewith,  and  payment  and
delivery  are to be made  directly  to such  registered  owner  at such  owner's
address shown on the records of the Company, or if Warrants are tendered for the
account of a bank,  dealer,  credit union,  savings  association or other entity
that is a member in good standing of a recognized  Medallion Program approved by
the Securities  Transfer  Association  Inc. (each such entity being  hereinafter
referred to as an "Eligible Institution"). In all other cases, all signatures on
the Letter of  Transmittal  must be guaranteed by an Eligible  Institution.  See
Instruction  2 of the Letter of  Transmittal.  If a Warrant is registered in the
name of a person other than the signer of a Letter of Transmittal, or if payment
is to be made,  or Warrants not  purchased  or tendered  are to be issued,  to a
person  other  than the  registered  owner,  the  Warrant  must be  endorsed  or
accompanied by an appropriate  power,  in either case signed exactly as the name
of the  registered  owner  appears on the  Warrant,  with the  signature  on the
Warrant or power guaranteed by an Eligible  Institution.  In all cases,  payment
for Warrants  tendered  and  accepted for payment  pursuant to the Offer will be
made only after timely  receipt by the  Depositary of such Warrants (or a timely
confirmation  of  book-entry  transfer of such  Warrants  into the  Depositary's
account at one of the Book-Entry Transfer Facilities),  a properly completed and
duly executed  Letter of Transmittal (or facsimile  thereof),  with any required
signature guarantee (or in the case of book-entry transfer,  an Agent's Message)
and any other required  documents.  The method of delivery of the Warrants is at
the election  and risk of the  tendering  warrantholder.  If delivery is made by
mail,  registered  mail with return  receipt  requested,  properly  insured,  is
recommended.


   FEDERAL BACKUP WITHHOLDING.  Unless an exemption applies under the applicable
law and regulations  concerning "backup  withholding" of Federal income tax, the
Depositary  will be required to withhold,  and will  withhold,  31% of the gross
proceeds  otherwise  payable to a  warrantholder  or other payee pursuant to the
Offer  unless the  warrantholder  or other  payee  provides  such  person's  tax
identification number (social security number or employer identification number)
and certifies that such number is correct. Each tendering  warrantholder,  other
than a noncorporate  foreign  warrantholder,  should  complete and sign the main
signature  form and the  Substitute  Form W-9  included as part of the Letter of
Transmittal,  so as to provide the  information and  certification  necessary to
avoid backup withholding, unless an applicable exemption exists and is proved in
a manner  satisfactory to the Company and the Depositary.  Noncorporate  foreign
warrantholders  should  generally  complete and sign a Form W-8,  Certificate of
Foreign Status, a copy of which may be obtained from the Depositary, in order to
avoid backup withholding.


   BOOK-ENTRY DELIVERY. The Depositary will establish an account with respect to
the Warrants at each of the Book-Entry  Transfer  Facilities for purposes of the
Offer  within two business  days after the date of this Offer to  Purchase.  Any
financial  institution that is a participant in a Book-Entry Transfer Facility's
system may make book-entry  delivery of the Warrants by causing such facility to
transfer  Warrants  into  the  Depositary's  account  in  accordance  with  such
facility's procedure for such transfer.  Even though delivery of Warrants may be
effected through book-entry transfer into the Depositary's account at one of the
Book-Entry Transfer Facilities, a properly completed and duly executed Letter of
Transmittal (or facsimile thereof),  with any required signature  guarantees (or
an  Agent's  Message)  and other  required  documents,  must,  in any  case,  be
transmitted  to and received by the Depositary at one of its addresses set forth
on the back cover of this Offer to Purchase prior to the Expiration Date, or the
guaranteed delivery procedure set forth below must be followed. Delivery of this
Letter of Transmittal and any other required  documents to one of the Book-Entry
Transfer Facilities does not constitute delivery to the Depositary.


   GUARANTEED DELIVERY.  If a warrantholder  desires to tender Warrants pursuant
to the Offer and such warrantholder's Warrants are not immediately available (or
the procedures for book-entry transfer cannot be completed on a timely basis) or
time will not permit all required  documents to reach the Depositary  before the
Expiration  Date, such Warrants may  nevertheless be tendered  provided that all
the following conditions are satisfied: 

         (a) such tender is made by or through an Eligible Institution;

         (b) the Depositary receives (by hand, mail, or facsimile  transmission)
      on or prior to the Expiration Date, a properly completed and duly executed
      Notice of Guaranteed  Delivery  substantially  in the form the Company has
      provided with this Offer to Purchase; and

         (c) the tendered  Warrants in proper form for transfer (or confirmation
      of book-entry  transfer of such Warrants into the Depositary's  account at
      one of the  Book-Entry  Transfer  Facilities),  together  with a  properly
      completed  and  duly  executed  Letter  of  Transmittal  (or  a  facsimile
      thereof),  with  any  required  signature  guarantees  (or in the  case of
      Book-Entry transfer,  an Agent's Message) and any other documents required
      by the Letter of Transmittal,  are received by the Depositary  within five
      NYSE trading days after the date of execution of such Notice of Guaranteed
      Delivery.


   The term  "Agent's  Message"  means a message,  transmitted  by a  Book-Entry
Transfer  Facility to, and received by, the Depositary and forming a part of the
confirmation of book-entry transfer,  which states that such Book-Entry Transfer
Facility has received an express  acknowledgement  from the  participant in such
Book-Entry  Transfer Facility tendering the Warrants,  that such participant has
received  and agrees to be bound by the terms of the Letter of  Transmittal  and
that the Purchaser may enforce such agreement against the participant. 


   DETERMINATIONS  OF VALIDITY OF WARRANTS;  REJECTION  OF  WARRANTS;  WAIVER OF
DEFECTS;  NO  OBLIGATION  TO GIVE NOTICE OF  DEFECTS.  All  questions  as to the
validity,  form,  eligibility  (including  time of receipt) and  acceptance  for
payment of any tender of Warrants will be determined by the Company, in its sole
discretion,  which determination shall be final and binding on all parties.  The
Company  reserves the absolute  right to reject any or all tenders it determines
not to be in proper  form or the  acceptance  for  payment of which may,  in the
opinion of the  Company's  counsel,  be unlawful.  The Company also reserves the
absolute  right to waive any of the  conditions  of the Offer and any  defect or
irregularity  in the tender of any  particular  Warrants.  No tender of Warrants
will be deemed to be properly made until all defects or irregularities have been
cured or waived. Neither the Company, the Depositary, the Information Agent, the
Dealer  Managers  nor any other person is or will be obligated to give notice of
any  defects  or  irregularities  in  tenders,  and none of them will  incur any
liability for failure to give any such notice. 

SECTION 6. WITHDRAWAL RIGHTS


   Except as otherwise provided in this Section 6, a tender of Warrants pursuant
to the Offer is  irrevocable.  Warrants  tendered  pursuant  to the Offer may be
withdrawn  at any time  before  the  Expiration  Date  and,  unless  theretofore
accepted  for  payment by the Company as  described  in the first  paragraph  of
Section 7, may also be withdrawn after 12:00 midnight, Eastern Time, on July 13,
1995.

   For a withdrawal to be effective,  the Depositary must timely receive (at one
of its  addresses  set forth on the back  cover of this Offer to  Purchase),  by
written,  telegraphic or facsimile  transmission,  a notice of withdrawal.  Such
notice of  withdrawal  must specify the name of the person  having  tendered the
Warrants to be withdrawn, the number of Warrants to be withdrawn and the name of
the  registered  owner,  if different  from that of the person who tendered such
Warrants.  If the Warrants  have been  delivered or otherwise  identified to the
Depositary,  then,  prior  to  the  release  of  such  Warrants,  the  tendering
warrantholder  must also  submit  the  serial  numbers  shown on the  particular
Warrants, and the signature on the notice of withdrawal must be guaranteed by an
Eligible  Institution  (except in the case of  Warrants  tendered by an Eligible
Institution).  If Warrants  have been  delivered  pursuant to the  procedure for
book-entry  transfer  set forth in  Section  5, the  notice of  withdrawal  must
specify  the name and the  number of the  account at the  applicable  Book-Entry
Transfer  Facility to be credited  with the  withdrawn  Warrants  and  otherwise
comply with the procedures of such facility.

   All  questions  as to the form and  validity  (including  timely  receipt) of
notices of withdrawal will be determined by the Company, in its sole discretion,
which  determination  shall be final and  binding  on all  parties.  None of the
Company, the Depositary, the Information Agent, the Dealer Managers or any other
person  is  or  will  be  obligated  to  give  any  notice  of  any  defects  or
irregularities  in any  notice of  withdrawal,  and none of them will  incur any
liability  for  failure to give any such  notice.  A  withdrawal  of a tender of
Warrants may not be rescinded,  and Warrants properly  withdrawn will thereafter
be deemed not validly  tendered  for purposes of the Offer.  Withdrawn  Warrants
may,  however,  be retendered  before the Expiration Date by again following the
applicable procedures described in Section 5.


SECTION 7. ACCEPTANCE FOR PAYMENT OF WARRANTS AND PAYMENT OF PURCHASE
           PRICE

   Upon the terms and subject to the conditions of the Offer, promptly after the
Expiration  Date,  the Company will purchase and pay the Purchase  Price for any
and all Warrants  (subject to certain matters discussed in Section 4 and Section
13) as are properly  tendered  and not  withdrawn as permitted in Section 6. For
purposes of the Offer,  the Company will be deemed to have  accepted for payment
(and thereby  purchased)  Warrants which are tendered and not withdrawn when, as
and if it gives oral or written  notice to the  Depositary of its  acceptance of
such Warrants for payment pursuant to the Offer.

   Payment for  Warrants  pursuant to the Offer will be made by  depositing  the
aggregate  Purchase Price therefor with the Depositary,  which will act as agent
for  tendering  warrantholders  for the purpose of  receiving  payment  from the
Company   and   transmitting   payment   to   the   tendering    warrantholders.
Notwithstanding  any other provision  hereof,  payment for Warrants accepted for
payment  pursuant  to the  Offer  will in all cases be made  only  after  timely
receipt by the Depositary of the accepted Warrants (or a timely  confirmation by
a Book-Entry  Transfer  Facility of book-entry  transfer of such Warrants to the
Depositary),  a properly  completed and duly executed  Letter of Transmittal (or
facsimile  thereof) with any required  signature  guarantees (or, in the case of
book-entry transfer, an Agent's Message) and any other required documents. Under
no circumstances  will interest be paid by the Company,  regardless of any delay
in making such payment.

   The Company  will pay any stock  transfer  taxes with respect to the transfer
and sale of Warrants to it pursuant to the Offer.  If,  however,  payment of the
Purchase  Price is to be made to, or if Warrants  not  tendered or accepted  for

      or

         (g) (i) any person,  entity or "group" (as that term is used in Section
      13(d)(3) of the Exchange Act) shall have acquired, or proposed to acquire,
      beneficial  ownership of more than 5% of the Company's  outstanding common
      stock  (other  than a  person,  entity,  or  "group"  which  had  publicly
      disclosed  such  ownership  in a  Schedule  13D  or 13G  (or an  amendment
      thereto) on file with the Commission prior to May 16, 1995),  (ii) any new

      shall   have   filed  a   Notification   and   Report   Form   under   the

      announcement  reflecting  an intent to acquire  the  Company or any of its
      subsidiaries or any of their respective assets or securities;

and, in the sole judgment of the Company, in any such case and regardless of the
circumstances  (including any action or inaction by the Company)  giving rise to
such  condition,  such event makes it  inadvisable  to proceed with the Offer or
with such acceptance for payment or payment.

   The foregoing  conditions  are for the sole benefit of the Company and may be
asserted or waived by the Company regardless of the circumstances (including any
action or inaction by the Company)  giving rise to any such  condition,  and any
such  condition  may be waived by the Company,  in whole or in part, at any time
and  from  time to time in its  sole  discretion;  provided,  however,  that the
Exchange Act and the rules and regulations  promulgated  thereunder require that
all conditions to the Offer, other than those relating to the receipt of certain
necessary  governmental  approvals,  must be  satisfied  or waived  prior to the
Expiration  Date.  The  Company's  failure  at any time to  exercise  any of the
foregoing rights shall not be deemed a waiver of any such right or the waiver of
any such right with respect to particular facts or circumstances;  and each such
right  shall be deemed an ongoing  right  which may be  asserted at any time and
from time to time.  Any  determination  by the  Company  concerning  the  events
described  above  and  any  related  judgment  by  the  Company   regarding  the
inadvisability  of proceeding  with the acceptance of payment or payment for any
tendered Warrants will be final and binding on all parties.

current  market  quotation for the Warrants.  As of May 5, 1995, the Company had
issued and outstanding  4,067,971  Warrants held by  approximately  4,300 record
holders. 

SECTION 10. CERTAIN INFORMATION CONCERNING THE COMPANY

   The Company is a fully-integrated  producer of electrolytic  copper and ranks
among the largest U.S. copper  producers.  Magma's  principal  products are high
quality copper  cathode and copper rod, the latter being the basic  feedstock of
the copper wire and cable industry.


   The Company owns and operates  underground copper mines at its San Manuel and
Superior Mining Divisions, an open-pit copper mine at its Pinto Valley Division,
and in situ  leaching  operations  at its San  Manuel  and Pinto  Valley  Mining
Divisions,  all of which are  located in  southeastern  Arizona.  Recently,  the
Company  began  development  of its  Robinson  mine  located  near Ely,  Nevada.
Production at this mine is expected to commence in the first quarter of 1996. In
the fourth quarter of 1994, the Company  completed the  acquisition of a company
which  owns  one  of  the  largest  operating  copper  mines  in  Southern  Peru
("Tintaya").  Tintaya  operates an open-pit mine and concentrator and is engaged
in a variety of development projects at this property.

   The Company operates the largest and most modern copper smelting and refining
complex  in the  United  States.  The  Company's  smelter,  which  was  recently
expanded,  has a rated production capacity of 720 million pounds of copper anode
per year,  representing  approximately 25% of U.S. copper smelting capacity.  In
addition to smelting  and refining its own copper  concentrate  production,  the
Company  smelts and refines a  substantial  amount of copper  concentrates  on a
custom  basis for, or  purchased  from,  third  parties,  the profits from which
effectively  reduce the Company's  overall  break-even cost of producing  copper
from its mines.

(Footnotes to table on previous page)

 (1) Certain  freight costs have been  reclassified  as a deduction from revenue
     rather than as a selling  expense.  All years have been restated to reflect
     this change.


 (2) Excludes  capitalized  interest of $17.7  million for 1994 and $7.8 million
     for 1993,  and $5.8 million and $4.8  million for the quarters  ended March
     31, 1995 and 1994, respectively.

 (3) In May 1992,  the Company  redeemed  all $100  million of its  Subordinated
     Reset Debentures and paid a premium on the early repayment of this debt.

 (4) There were no cash dividends paid or declared on Common Stock during any of
     these periods.

 (5) "EBITDA" is earnings  before net  interest  expense,  taxes,  depreciation,
     depletion and amortization.

 (6) In calculating the ratios:  (i) "earnings"  consist of income before taxes,
     accounting changes and extraordinary  items plus fixed charges adjusted for
     capitalized interest and amortization of previously  capitalized  interest;
     (ii) "fixed charges" consist of interest (including  capitalized  interest)
     and the estimated  interest portion of lease rental expenses,  amortization
     of debt expenses and write- offs of loan costs;  and (iii)  preferred stock
     dividends  include dividends paid in zero coupon notes and shares of Common
     Stock.  In calculating the ratio of earnings to fixed charges and preferred
     stock dividends,  the preferred stock dividend requirements were assumed to
     be  equal  to  the  pretax   earnings   required  to  cover  such  dividend
     requirements.  The  amount  of  such  pretax  earnings  required  to  cover
     preferred  stock  dividends was computed using tax rates for the applicable
     year.  Preferred  stock dividends are included in total "fixed charges" and
     deducted from "earnings."

 (7) Saleable copper contained in concentrates plus electrowon copper.

 (8) Includes  all new  sulfide  concentrate  smelted by the Company for its own
     account and concentrate  smelted for others on a custom basis and shipments
     of unrefined copper.

 (9) Includes  all  electrolytic  copper  produced  by the  Company  for its own
     account and refined copper produced for others on a custom basis.

(10) Includes production from the Company's concentrates and the Company's share
     of production from custom concentrates.

(11) All  reserves  were   determined   based  upon  a  pricing   assumption  of
     approximately $0.80 per pound of copper.

                                  INSTRUCTIONS

   1. DELIVERY OF THIS LETTER OF TRANSMITTAL AND CERTIFICATES FOR WARRANTS. This
Letter of Transmittal is to be used (i) if  certificates  for Warrants are to be
physically  delivered to the Depositary  herewith,  or (ii) if tenders are to be
made according to the guaranteed  delivery  procedures set forth in the Offer to
Purchase.

   2. SIGNATURES ON THIS LETTER OF  TRANSMITTAL;  POWERS AND  ENDORSEMENTS.  The
signature(s)  of the  registered  holder(s) on this Letter of Transmittal in Box
two must  correspond  with the  name(s) as  written on the face of the  Warrants
without  alteration,  enlargement  or any change  whatsoever.  

      (a) If any of the Warrants are held of record by two or more persons,  all
   such persons must sign this Letter of Transmittal.

      (b) If any of the Warrants are registered in different  names,  it will be
   necessary  to  complete,   sign  and  submit  as  many  separate  Letters  of
   Transmittal and any necessary  accompanying  documents as there are different
   registrations.

      (c) If this Letter of Transmittal is signed by the registered holder(s) of
   the Warrants,  no  endorsements  of Warrants or separate powers are required,
   unless  certificates  for  Warrants not tendered are to be issued in the name
   of,  or  delivered  to,  any  person  other  than the  registered  holder(s).
   Signatures  on any such  Warrants or powers must be guaranteed by an Eligible
   Institution (unless signed by an Eligible Institution).

      (d) If this  Letter of  Transmittal  is signed by a person  other than the
   registered  holder(s)  of the  Warrants,  such  Warrants  must be endorsed or
   accompanied by appropriate  powers, and in either case, signed exactly as the
   name(s) of the registered holder(s) appear(s) on such Warrants. Signatures on
   any such  Warrants or powers must be  guaranteed  by an Eligible  Institution
   (unless signed by an Eligible Institution).

      (e) If this Letter of Transmittal or any certificates or powers are signed
   by a trustee, executor, administrator, guardian, attorney-in-fact, officer of
   a  corporation,  or other  person  acting in a  fiduciary  or  representative
   capacity,  such person should so indicate when signing,  and unless waived by
   the Company,  proper evidence satisfactory to the Company of the authority of
   such person to so act must be submitted with this Letter of Transmittal.

   3.  TRANSFER  TAXES.  The Company  will pay or cause to be paid all  transfer
taxes,  if any, with respect to the tender of any Warrants to it pursuant to the
Offer. If, however,  (i) payment of the purchase price for the Warrants is to be
made to, or certificates  for any Warrants not tendered or accepted for purchase
are to be issued in the name of, or  delivered  to,  any  person  other than the
registered  holder(s),  (ii) tendered Warrants are registered in the name of any
person  other than the person  signing  the  Letter of  Transmittal,  or (iii) a
transfer  tax is imposed for any reason  other than the  transfer or sale of the
Warrants to the Company  pursuant to the Offer, the amount of any transfer taxes
(whether  imposed on the  registered  holder(s)  or such other  person)  will be
payable by the tendering holder(s).  Unless satisfactory evidence of the payment
of such taxes, or exemption therefrom, is submitted herewith, the amount of such
transfer taxes will be deducted from the purchase price payable to the tendering
holder(s).  EXCEPT AS PROVIDED IN THIS  INSTRUCTION  3, IT WILL NOT BE NECESSARY
FOR TRANSFER TAX STAMPS TO BE AFFIXED TO THE WARRANT CERTIFICATES LISTED IN THIS
LETTER OF TRANSMITTAL.

   4. SPECIAL  ISSUANCE  AND  DELIVERY  INSTRUCTIONS.  If  certificates  for any
Warrants  not  tendered  are to be issued or  delivered  in the name of a person
other than the person(s)  signing this Letter of  Transmittal,  the  appropriate
boxes on this Letter of Transmittal should be completed.

   5. SUBSTITUTE FORM W-9. Under Federal income tax laws, each tendering  holder
must  provide the Company with such  holder's  correct  taxpayer  identification
number by completing the Substitute  Form W-9 set forth below. If the Company is
not provided with the correct taxpayer  identification number, the holder may be
subject to a $50 penalty  imposed by the Internal  Revenue  Service,  as well as
"backup  withholding"  as described  below.  Certain holders  (including,  among
others,  all  corporations  and certain foreign  individuals) are not subject to
these backup  withholding and reporting  requirements.  For further  information
concerning  backup  withholding and  instructions  for completing the Substitute
Form W-9 (including how to obtain a taxpayer identification number if you do not
have one and how to complete  the  Substitute  Form W-9 if Warrants  are held in
more than one name),  consult the  enclosed  "Guidelines  for  Certification  of
Taxpayer Identification Number on Substitute Form W-9."

   Failure to complete the  Substitute  Form W-9 will not, by itself,  cause the
Warrants to be deemed to be invalidly tendered,  but may require the Company, in
certain  circumstances,  to  withhold  31% of the  amount of any  payments  made
pursuant  to the Offer to  Purchase.  Backup  withholding  is not an  additional
Federal income tax. Rather, the Federal income tax liability of a person subject
to  backup  withholding  will be  reduced  by the  amount  of tax  withheld.  If
withholding  results in an  overpayment  of taxes, a refund may be obtained from
the Internal Revenue Service.

   6. INADEQUATE  SPACE.  If  the  space  provided   herein is  inadequate,  the
Warrant certificate numbers and/or the number of Warrants and any other required
information  should  be  listed  on a  separate  schedule  attached  hereto  and
separately  signed on each  page  thereof in the same  manner as this  Letter of
Transmittal is signed.

   7. PARTIAL TENDERS (NOT APPLICABLE TO WARRANTHOLDERS WHO TENDER BY BOOK-ENTRY
TRANSFER). If fewer than all the Warrants evidenced by any certificate submitted
are to be tendered,  fill in the number of Warrants  which are to be tendered in
the box entitled "Number of Warrants Tendered." In such case, new certificate(s)
for the remainder of the Warrants that were evidenced by your old certificate(s)
will be sent to you,  unless  otherwise  provided in the  appropriate box marked
"Special Payment  Instructions"  and/or "Special Delivery  Instructions" on this
Letter of  Transmittal,  as soon as practicable  after the Expiration  Date. All
Warrants represented by certificates  delivered to the Depositary will be deemed
to have been tendered unless otherwise indicated.

   8. REQUESTS FOR ASSISTANCE OR ADDITIONAL COPIES.  Requests for assistance may
be directed to the Information Agent at its addresses set forth below.  Requests
for  additional  copies of the Offer to Purchase and this Letter of  Transmittal
may be directed to the  Information  Agent or to  brokers,  dealers,  commercial
banks or trust companies.

                                  May 16, 1995

To Our Warrantholders:

   We are offering to you, our  warrantholders,  the  opportunity to tender your
Common Stock Warrants, $8.50 Exercise Price (the "Warrants"), to the Company for
$8.25  per  Warrant  in cash,  as more  particularly  described  in the Offer to
Purchase  and Letter of  Transmittal  (which  together  constitute  the "Offer")
included in the accompanying materials. On May 12, 1995, the closing sales price
of a Warrant on the New York Stock Exchange  Composite Tape was $7.00. The Offer
represents a 17% premium over this price.

   If you wish to accept this Offer,  you must  follow the  procedures  for such
tender  described  in the  Offer to  Purchase  under  the  heading  "Section  5.
Procedure for Tendering Warrants." All required documentation  described in such
Section  5 must be  received  by the  Depositary  (as  defined  in the  Offer to
Purchase),  by 12:00  midnight,  Eastern  Time,  on June 14, 1995, or such later
date,  if any, to which the Company  shall have  extended  the Offer in its sole
discretion.  Holders  who do not wish to accept  this  Offer may still  exercise
their  Warrants  and  acquire  shares for $8.50 for each  Warrant  held prior to
November 30, 1995, the expiration date of the Warrants.

   Additional   information  on  the  Offer  is  included  in  the  accompanying
materials. If you have any questions on these materials, please call D.F. King &
Co., Inc., the Information Agent for the Offer, at (212) 269-5550.

   We appreciate your consideration of this Offer.


                                   Sincerely,




                                       /s/ J. Burgess Winter

   This  announcement  is neither an offer to purchase nor a solicitation  of an
offer to sell.  The Offer is made solely by the Offer to Purchase  dated May 16,
1995 and the related  Letter of  Transmittal  and is not being made to (nor will
tenders be accepted  from or on behalf of)  holders of Warrants  residing in any
jurisdiction  in which the making of the Offer or the  acceptance  thereof would
not be in compliance with the laws of such jurisdiction. In any jurisdiction the
securities  laws of which  require the Offer to be made by a licensed  broker or
dealer,  the Offer  shall be deemed made on behalf of the Company by one or more
brokers or dealers licensed under the laws of such jurisdiction.

                      NOTICE OF OFFER TO PURCHASE FOR CASH

                              MAGMA COPPER COMPANY
                                       OF
                               ANY AND ALL OF ITS
                          LISTED COMMON STOCK WARRANTS
                              $8.50 EXERCISE PRICE
                                       AT
                         $8.25 PER COMMON STOCK WARRANT

   Magma Copper Company, a Delaware corporation (the "Company"),  is offering to
purchase any and all of its listed Common Stock  Warrants,  $8.50 Exercise Price
(the "Warrants"), listed on the New York Stock Exchange, at $8.25 per Warrant in
cash, upon the terms and conditions set forth in the Offer to Purchase dated May
16, 1995 (the "Offer to  Purchase"),  and in the related  Letter of  Transmittal
(which  together  constitute  the  "Offer").  Each  Warrant  entitles the holder
thereof to purchase one share of Common Stock,  $.01 par value per share, of the
Company at $8.50 per share.

   THE OFFER AND WITHDRAWAL RIGHTS WILL EXPIRE AT 12:00 MIDNIGHT,  EASTERN TIME,
ON JUNE 14, 1995, UNLESS THE OFFER IS EXTENDED.

   THE  COMPANY,  ITS BOARD OF  DIRECTORS  AND ITS  EXECUTIVE  OFFICERS  MAKE NO
RECOMMENDATION AS TO WHETHER ANY WARRANTHOLDER  SHOULD TENDER ANY OR ALL OF SUCH
WARRANTHOLDER'S WARRANTS PURSUANT TO THE OFFER. EACH WARRANTHOLDER MUST MAKE ITS
OWN DECISION WHETHER TO TENDER WARRANTS AND, IF SO, HOW MANY WARRANTS TO TENDER.

   The Company is making the Offer to eliminate  the potential  dilutive  effect
that would occur if the  Warrants  are  exercised  by the holders  thereof on or
before  November  30,  1995,  the date such  Warrants  expire.  The Company also
believes  the Offer is fair to  holders  of  Warrants.  The Offer  will  provide
warrantholders  who are  considering  a sale of all or a portion of the Warrants
the  opportunity  to sell those  Warrants  for cash at a premium over the market
price  prevailing  prior to the  announcement of the Offer and without the usual
transaction costs associated with open-market  sales. See Section 1 of the Offer
to Purchase. 


   THE  OFFER IS NOT  CONDITIONED  UPON ANY  MINIMUM  NUMBER OF  WARRANTS  BEING
TENDERED AND, EXCEPT AS SET FORTH IN SECTION 8 OF THE OFFER TO PURCHASE, MAY NOT
BE  WITHDRAWN  BY THE  COMPANY.  THE COMPANY HAS ALSO AGREED NOT TO DECREASE THE
PURCHASE  PRICE FOR THE WARRANTS  BEING SOUGHT,  DECREASE THE NUMBER OF WARRANTS
SUBJECT TO THE OFFER OR CHANGE THE  CONSIDERATION  TO BE PAID THEREFOR FROM CASH
TO NON-CASH INSTRUMENTS.

   Upon the terms and  conditions  of the Offer,  the  Company  will  accept for
payment (and  thereby  purchase)  any and all Warrants as are properly  tendered
(and not withdrawn) on or before 12:00 midnight, Eastern Time, on June 14, 1995,
or the latest  time and date at which the Offer,  if  extended  by the  Company,
shall expire (the "Expiration  Date"). The Company expressly reserves the right,
in its sole  discretion,  at any time or from time to time, to extend the period
of time during which the Offer is open by giving oral or written  notice of such
extension  to the  Depositary  and  making a public  announcement  thereof.  See
Sections 4, 5, 7 and 13 of the Offer to Purchase.

   Subject to the  provisions  in Section 6 of the Offer to  Purchase,  Warrants
tendered  pursuant  to  the  Offer  may be  withdrawn  at any  time  before  the
Expiration Date and, unless theretofore accepted for payment by the Company, may
also be withdrawn after 12:00 midnight, Eastern Time, on July 13, 1995.
See Section 6 of the Offer to Purchase.

   For a withdrawal to be  effective,  the  Depositary  must receive on a timely
basis  (at one of its  addresses  set  forth on the back  cover of the  Offer to
Purchase),  by  written,  telegraphic  or  facsimile  transmission,  a notice of
withdrawal. Such notice of withdrawal must specify the name of the person having
tendered the Warrant to be withdrawn, the number of Warrants to be withdrawn and
the name of the  registered  owner,  if  different  from that of the  person who
tendered  such  Warrants.  If the  Warrants  have been  delivered  or  otherwise
identified to the Depositary,  then, prior to the release of such Warrants,  the
tendering  warrantholder  must  also  submit  the  serial  numbers  shown on the
particular  Warrants  and the  signature  on the  notice of  withdrawal  must be
guaranteed by an Eligible  Institution  (as defined in Section 5 of the Offer to
Purchase) (except in the case of Warrants tendered by an Eligible  Institution).
If  Warrants  have been  delivered  pursuant  to the  procedure  for  book-entry
transfer  set  forth in  Section  5 of the  Offer to  Purchase,  the  notice  of
withdrawal  must  specify the name and number of the  account at the  applicable
Book-Entry  Transfer Facility (as defined in Section 5 of the Offer to Purchase)
to be  credited  with the  withdrawn  Warrants  and  otherwise  comply  with the
procedures  of such  facility.  A withdrawal  of a tender of Warrants may not be
rescinded,  and any Warrants  properly  withdrawn will  thereafter be deemed not
validly tendered for purposes of the Offer.  Withdrawn Warrants may, however, be
retendered  before  the  Expiration  Date  by  again  following  the  applicable
procedures described in Section 5 of the Offer to Purchase. 

   THE  OFFER TO  PURCHASE  AND THE  LETTER  OF  TRANSMITTAL  CONTAIN  IMPORTANT
INFORMATION THAT SHOULD BE READ BEFORE ANY DECISION IS MADE WITH RESPECT TO THE


OFFER. These documents are being mailed to recordholders of Warrants and will be
furnished to brokers,  dealers,  banks and similar persons whose nominees appear
on the  Company's  warrantholders  list or,  if  applicable,  who are  listed as
participants in a clearing  agency's  security  position  listing for subsequent
transmittal to beneficial owners of Warrants.

   The information  required to be disclosed by Rule  13e-4(d)(1) of the General
Rules and Regulations under the Securities  Exchange Act of 1934 is contained in
the Offer to Purchase and is incorporated herein by reference.


   Any questions or requests for assistance  may be directed to the  Information
Agent and the Dealer  Managers at the addresses and telephone  numbers set forth
below.  Requests  for  additional  copies  of the Offer to  Purchase,  Letter of
Transmittal or other tender offer  materials may be directed to the  Information
