("Wheaton River") by C$285 million, funded through a committed financing from a major international investment bank. COEUR'S INCREASED CASH COMPONENT NOW ENABLES COEUR TO PAY WHEATON RIVER SHAREHOLDERS A MINIMUM OF C$1.00 PER WHEATON RIVER SHARE IN CASH - REPRESENTING 23% OF THE CURRENT VALUE OF COEUR'S MERGER PROPOSAL.(1) With a new vote of Wheaton River shareholders now scheduled for July 6, 2004 regarding the proposed Wheaton River-IAMGold Corporation ("IAMGold") plan of arrangement, COEUR STRONGLY RECOMMENDS THAT ALL WHEATON RIVER SHAREHOLDERS VOTE AGAINST THE PROPOSED IAMGOLD TRANSACTION ON THE GREEN PROXY CARD TODAY. By doing so, you will be sending a strong message to your Board of Directors that you want it to negotiate with Coeur regarding Coeur's enhanced superior merger proposal. COEUR IS COMMITTED TO COMPLETING A COMBINATION WITH WHEATON RIVER While it is Coeur's desire to complete a friendly business combination with Wheaton River by way of a plan of arrangement, if the Wheaton River Board continues to refuse to negotiate with Coeur, Coeur will consider other transaction alternatives, including making a formal offer directly to the shareholders of Wheaton River. DON'T MISS THE OPPORTUNITY TO VOTE AT THE NEW SPECIAL MEETING. THE EARLY CUTOFF FOR VOTING YOUR PROXY IS 11:00 AM (TORONTO TIME) ON JULY 2, 2004.

WE BELIEVE COEUR'S ENHANCED MERGER PROPOSAL IS CLEARLY SUPERIOR TO THE WHEATON RIVER-IAMGOLD PLAN OF ARRANGEMENT AND IN THE BEST INTERESTS OF ALL WHEATON RIVER SHAREHOLDERS --------------- (1) Assuming all of the current outstanding Wheaton River shareholders elect to receive cash, based on the number of issued and outstanding Wheaton River common shares on May 27, 2004, the date Coeur first announced its proposal. Based on closing share prices on May 27, 2004, Coeur's enhanced merger proposal will provide Wheaton River shareholders a total value of approximately C$5.00 for each Wheaton River common share, of which at least C$1.00 is cash. Coeur's enhanced merger proposal represents: - A premium of C$0.94 for each Wheaton River common share over the IAMGold proposal based on closing share prices on May 27, 2004. - An increase of approximately 11% over Coeur's initial proposal that was announced on May 27, 2004. - A premium of 26% to Wheaton River's closing share price on May 27, 2004. - An opportunity for Wheaton River shareholders to receive 23% of the consideration (based on Coeur's closing share price on June 18, 2004) for their Wheaton River common shares in cash even if all Wheaton River shareholders choose to receive cash. IN CONTRAST, THE WHEATON RIVER-IAMGOLD PLAN OF ARRANGEMENT OFFERS WHEATON RIVER SHAREHOLDERS NO CASH WHATSOEVER AND LESS TOTAL VALUE, AS WELL AS LESS GROWTH, SIGNIFICANTLY LESS TRADING LIQUIDITY, NO OPERATING SYNERGIES, AND NO MANAGEMENT OPERATIONAL EXPERTISE. Under Coeur's enhanced merger proposal, Wheaton River shareholders may now elect to receive either: (i) $5.00 per Wheaton River common share in cash, subject to the maximum cash consideration discussed below; or (ii) Coeur common shares or shares of a Canadian subsidiary of Coeur exchangeable into Coeur common shares on a one-to-one basis at the exchange ratio of 0.731 Coeur common shares or Coeur exchangeable shares for each Wheaton River common share exchanged. There is no limit on the number of Wheaton River common shares that may be exchanged for Coeur common stock (or exchangeable shares). However, the maximum aggregate amount of cash that Coeur will pay to Wheaton River shareholders under the enhanced Coeur proposal is C$570 million. Therefore, elections to receive cash will be subject to proration if Wheaton River shareholders request in the aggregate to receive more than C$570 million. Based on the number of issued and outstanding Wheaton River common shares on May 27, 2004, if all Wheaton River shareholders elect to receive cash for their Wheaton River common shares, shareholders will receive C$1.00 per Wheaton River common share in cash and 0.577 common shares or Coeur exchangeable shares. If less than all Wheaton River shareholders elect the cash option, Wheaton River shareholders will receive up to C$5.00 per Wheaton River common share in cash (subject to proration based on the maximum aggregate cash consideration of C$570 million). A COMBINED COEUR-WHEATON RIVER WILL BE A GLOBAL LEADER IN THE PRECIOUS METALS INDUSTRY A combination of Coeur and Wheaton River will create a global leader in the precious metals industry, focused on the Americas, with one of the highest growth rates in the sector. Our combination will create the fourth largest North American precious metals company, enhance Coeur's position as the world's largest primary silver producer, and create a top 10 global gold producer with among the lowest cash costs in the industry. The combination will bring together Coeur's wholly owned mines and operating expertise in South America with Wheaton River's properties in South America. Based upon a preliminary review of Wheaton River's publicly available information, Coeur anticipates cost savings of US$8-10 million annually. The combined company, a totally unhedged precious metals producer, will have a strong balance sheet, increased financial flexibility, and industry leading trading liquidity on both the NYSE and TSX, providing excellent value to both Wheaton River and Coeur shareholders. COEUR IS WELL-POSITIONED FOR FUTURE SUCCESS Coeur is in a strong financial position, with US$235 million in cash and no net debt. In addition to our four operations, we have advanced development projects in Bolivia and Alaska that we expect will nearly double our gold production and increase our silver production by over 50% in the next three years. Between January 1, 2003 and May 27, 2004, Coeur's share price on the NYSE increased 157%, making Coeur one of the best performers in the precious metals sector. SEND A STRONG MESSAGE TO YOUR BOARD. VOTE AGAINST THE PROPOSED WHEATON RIVER-IAMGOLD PLAN OF ARRANGEMENT ON THE GREEN PROXY CARD TODAY. BY VOTING AGAINST THE PROPOSED IAMGOLD TRANSACTION ON THE GREEN PROXY CARD, YOU WILL BE SENDING A MESSAGE THAT YOUR BOARD OF DIRECTORS CAN'T IGNORE - THAT YOU WANT THEM TO NEGOTIATE WITH COEUR REGARDING OUR ENHANCED SUPERIOR MERGER PROPOSAL. Shareholders who previously voted AGAINST the IAMGold transaction, but whose votes were not counted at the June 8, 2004 Special Meeting as a result of Wheaton River's deadline to submit proxies, now have a fair opportunity to make their voices heard. Furthermore, there is now time for Wheaton River shareholders who may have voted in favor of the IAMGold transaction to revoke or change their vote. EVEN IF SHAREHOLDERS HAVE ALREADY VOTED AGAINST ON MANAGEMENT'S CARD, WE URGE YOU TO VOTE A LATER DATED GREEN PROXY CARD TO MAKE SURE THAT THIS TIME YOUR VOTE IS COUNTED. Wheaton River shareholders who wish to VOTE AGAINST the Wheaton River-IAMGold plan of arrangement can revoke or change their vote by simply submitting a GREEN proxy card. If shareholders have any questions about how to revoke or change their vote, please call MacKenzie Partners, Inc. at 1-800-322-2885 (toll-free) or 212-929-5500 (call collect). IN ORDER TO ENSURE THAT SHAREHOLDERS' VOTES ARE COUNTED AT THE SPECIAL MEETING, THE GREEN PROXY CARD MUST BE RECEIVED BY JULY 2, 2004 AT 11:00 AM (TORONTO TIME). Make certain your vote will count by signing, dating and mailing your GREEN proxy card today. Very truly yours, /s/ DENNIS E. WHEELER ----------------------------------------- Dennis E. Wheeler Chairman and Chief Executive Officer QUESTIONS AND ANSWERS FOR WHEATON RIVER SHAREHOLDERS 1. WHO IS COEUR D'ALENE MINES? Coeur d'Alene Mines is the world's largest primary silver producer and a growing low-cost producer of gold with a market capitalization approaching US$1 billion. In 2003, Coeur produced approximately 14.2 million ounces of silver and 119,500 ounces of gold. In 2004, Coeur expects that its production will increase to 14.5 million ounces of silver and 133,000 ounces of gold. Coeur owns two of the largest silver mines in the U.S.; two expanding low-cost mines in southern Chile and Argentina; and two advanced development projects, in Bolivia and Alaska. All of these properties are 100% owned. The Company also owns large land positions around its Idaho and South American mines, where major exploration is ongoing in 2004. None of the Company's gold or silver production is hedged. Internal growth project already in place have the potential of increasing production 50% by 2007. Coeur trades on the New York Stock Exchange under the symbol CDE. 2. WHY IS COEUR'S MERGER PROPOSAL SUPERIOR TO THE PROPOSED TRANSACTION WITH IAMGOLD? We believe Coeur's enhanced merger proposal is clearly superior to the Wheaton River-IAMGold plan of arrangement and in the best interests of all Wheaton River shareholders. Based on closing share prices on May 27, 2004, Coeur's enhanced merger proposal will provide Wheaton River shareholders a total value of approximately C$5.00 for each Wheaton River common share, of which at least C$1.00 is cash. Coeur's enhanced merger proposal represents: - A premium of C$0.94 for each Wheaton River common share over the IAMGold proposal based on closing share prices on May 27, 2004. - An increase of approximately 11% over Coeur's initial proposal that was announced on May 27, 2004. - A premium of 26% to Wheaton River's closing share price on May 27, 2004. - An opportunity for Wheaton River shareholders to receive 23% of the consideration (based on Coeur's closing share price on June 18, 2004) for their Wheaton River common shares in cash even if all Wheaton River shareholders choose to receive cash. In contrast, the Wheaton River-IAMGold plan of arrangement offers Wheaton River shareholders no cash whatsoever, less total value, less growth, significantly less trading liquidity, no operating synergies, and no management operational expertise. 3. WHY SHOULD SHAREHOLDERS VOTE AGAINST THE IAMGOLD TRANSACTION? IF I ALREADY SENT IN MANAGEMENT'S PROXY CARD, CAN I VOTE AGAIN OR CHANGE MY VOTE? By any measure, Coeur's enhanced merger proposal provides more value to Wheaton River shareholders than the IAMGold transaction. Coeur has boosted the cash component of its merger proposal to Wheaton River by C$285 million, funded through a committed financing from a major international investment bank. Coeur's increased cash component now enables Coeur to pay Wheaton River shareholders a minimum of C$1.00 per Wheaton River share in cash - representing 23% of the current value of Coeur's merger proposal.(1) --------------- (1) Assuming all of the current outstanding Wheaton River shareholders elect to receive cash, based on the number of issued and outstanding Wheaton River common shares on May 27, 2004, the date Coeur first announced its proposal. In contrast, the Wheaton River-IAMGold plan of arrangement offers Wheaton River shareholders no cash whatsoever and less total value, as well as less growth, significantly less trading liquidity, no operating synergies and no management operational expertise. The following chart clearly illustrates that the implied value per Wheaton River share of Coeur's proposal offers consistently higher value than the IAMGold proposal: COEUR'S PROPOSAL OFFERS CONSISTENTLY HIGHER VALUE (LINE GRAPH) Wheaton River shareholders who wish to VOTE AGAINST the Wheaton River-IAMGold plan of arrangement can revoke or change their vote by simply signing, dating and submitting a GREEN proxy card. If shareholders have any questions about how to revoke or change their vote, please call MacKenzie Partners, Inc. at 1-800-322-2885 (toll-free) or 212-929-5500 (collect). In order to allow for sufficient time for your GREEN proxy card to be counted at the reconvened Special Meeting, we urge you to sign, date and return the GREEN proxy card today. To ensure that your vote is counted at the Special Meeting, your GREEN proxy card must be received by July 2, 2004 at 11:00 am (Toronto time). In contrast, the Wheaton River-IAMGold plan of arrangement offers Wheaton River shareholders no cash whatsoever, less total value, less growth, significantly less trading liquidity, no operating synergies, and no management operational expertise. 4. WHAT REALLY HAPPENED AT THE JUNE 8, 2004 SPECIAL MEETING OF WHEATON RIVER SHAREHOLDERS? WHY IS THERE ANOTHER VOTE? Wheaton River had originally held an annual and special meeting of shareholders on June 8, 2004. The votes of certain Wheaton River shareholders were not counted at the first meeting. One of these shareholders commenced legal proceedings to ensure that it would be permitted to vote against the proposed business combination between Wheaton River and IAMGold. The new meeting is being convened following the initiation of these legal proceedings and the resulting supplemental interim order made by the Ontario Superior Court of Justice to set a new meeting date to allow Wheaton River shareholders to vote in respect of the IAMGold Proposal. The reconvened Special Meeting on July 6th will ensure that all Wheaton River shareholders have sufficient time to evaluate both Coeur's enhanced merger proposal and the IAMGold plan of arrangement. In order to ensure that your vote is counted at the Special Meeting, your GREEN proxy card must be received by the early proxy deadline cutoff of 11:00 am (Toronto time) on July 2, 2004. 5. WHAT ARE THE BENEFITS OF A COEUR-WHEATON RIVER COMBINATION? A combination of Coeur and Wheaton River will create a global leader in the precious metals industry, focused on the Americas, with one of the highest growth rates in the sector. Our combination will create the fourth largest North American precious metals company, enhance Coeur's position as the world's largest primary silver producer, and create a top 10 global gold producer with among the lowest cash costs in the industry. The combination will bring together Coeur's wholly owned mines and operating expertise in South America with Wheaton River's properties in South America. Based upon a preliminary review of Wheaton River's publicly available information, Coeur anticipates cost savings of US$8-10 million annually. A combined Coeur-Wheaton River will also have superior growth prospects and a reserves and production profile that is among the leaders in the industry. We strongly believe that the combined company will provide excellent value to both Wheaton River and Coeur shareholders. The combined company, a totally unhedged precious metals producer, will have a strong balance sheet, increased financial flexibility, and industry leading trading liquidity on both the NYSE and TSX. 6. WHAT IS COEUR'S FINANCIAL POSITION? WHAT ARE COEUR'S DEVELOPMENT OPPORTUNITIES? Coeur is in a strong financial position, with US$235 million in cash and no net debt. Between January 1, 2003 and May 27, 2004, Coeur's share price on the NYSE increased 157%, making Coeur one of the best performers in the precious metals sector. Coeur owns or leases, either directly or through its subsidiaries, silver and gold development projects in Bolivia (the San Bartolome silver project) and in Alaska (the Kensington gold property). These development projects are at the final feasibility stage and are expected to nearly double Coeur's gold production and increase its silver production by over 50% in the next three years. Coeur also controls strategic properties with exploration potential close to its existing mine operations. 7. WILL THE PROPOSED TRANSACTION AFFECT COEUR'S SILVER PREMIUM? Coeur shares do not have a silver premium and trade more in line with North American gold producers. Based on June 18(th) closing prices and as measured by analyst consensus net asset values, Coeur is trading slightly below North American intermediate gold producers. Going forward, the combined company will be the largest primary silver producer in the world and increase its position over its nearest rival by 50%. It will maintain the highest silver leverage of all competitors based on a US$1,000 invested per ounce of silver reserves. The new company's industry leading exposure to silver can only be a positive for the combined company's share price. In addition, Coeur, like other large U.S.-domiciled mining companies such as Newmont, Phelps Dodge and Alcoa, enjoys a liquidity benefit because of the strong retail following for the stocks in the United States. The combination of Coeur and Wheaton River with listings on both the NYSE and TSX will create one of the most liquid precious metals producers in the market place. In conclusion, we see upside potential in the combination for Wheaton River shareholders. 8. HAS COEUR NEGOTIATED WITH WHEATON RIVER REGARDING ITS ENHANCED MERGER PROPOSAL? Coeur wishes to complete a friendly plan of arrangement with Wheaton River with the full support of Wheaton River's Board, the recently formed Special Committee of the Board and management. Coeur has repeatedly invited Wheaton River's Board and its advisors to conduct due diligence on Coeur's assets in order to better understand the compelling rationale and superior value of a business combination between Coeur and Wheaton River. To date, Wheaton River has not taken Coeur up on this offer. Coeur remains open to speaking directly with the Board and management of Wheaton River to discuss its enhanced merger proposal. 9. HOW LONG WOULD IT TAKE COEUR TO COMPLETE A TRANSACTION WITH WHEATON RIVER? Coeur is prepared to promptly enter into an arrangement agreement with Wheaton River in form and substance substantially the same as the existing agreement between Wheaton River and IAMGold. Coeur's offer is not conditional on obtaining financing or additional due diligence. Coeur is hopeful that once Wheaton River shareholders VOTE AGAINST the IAMGold transaction and the Wheaton River Board enters into discussions with Coeur regarding its enhanced merger proposal, both companies will move forward expeditiously in a constructive manner to consummate its proposal in the form of a plan of arrangement. 10. HOW DOES GOLDEN STAR'S OFFER FOR IAMGOLD IMPACT MY VOTE? Golden Star's offer for IAMGold may influence IAMGold shareholders in their determination about whether or not to approve the Wheaton River-IAMGold plan of arrangement. IAMGold will be conducting a meeting of its shareholders to vote on the proposed Wheaton River-IAMGold plan of arrangement on June 29, 2004. The Wheaton River-IAMGold plan of arrangement requires approval by the shareholders of both companies. A rejection of the plan of arrangement by IAMGold shareholders would prevent the consummation of that transaction.

The information concerning Wheaton contained in this Circular has been taken from or is based upon various publicly available documents or records on file with Canadian securities regulatory authorities (including the Wheaton Proxy Circular). Except as otherwise provided in this Circular, although Coeur has no knowledge that would indicate that any information contained herein taken from or based upon such documents and records is untrue or incomplete, Coeur does not assume any responsibility for the accuracy or completeness of the information taken from, or based upon, such documents and records or for any failure by Wheaton to disclose publicly events or facts which may have occurred, or which may affect the significance or accuracy of any such information but which are unknown to Coeur. The address of Wheaton is Waterfront Centre, Suite 1560-200 Burrard Street, Vancouver, British Columbia, V6C 3L6. Unless otherwise indicated, all currency references in this Circular are to Canadian dollars. THE COEUR PROPOSAL Coeur has announced three proposals to acquire the common shares of Wheaton. With each proposal, Coeur has simplified and enhanced the consideration to be received by Wheaton shareholders for their Wheaton common shares. AT ALL TIMES, EACH OF THE COEUR PROPOSALS HAS BEEN SUPERIOR TO THE IAMGOLD PROPOSAL. THE ENHANCED COEUR PROPOSAL On June 21, 2004, Coeur announced an increase in the cash consideration payable for Wheaton common shares to $570 million by arranging for a financing commitment from a major international investment bank (the "Enhanced Coeur Proposal"). Under the Enhanced Coeur Proposal, Wheaton shareholders may elect to receive either: - $5.00 per Wheaton common share in cash, subject to the maximum cash consideration discussed below; or - Coeur common shares or shares of a Canadian subsidiary of Coeur exchangeable into Coeur common shares on a one-to-one basis (the "Canadian Exchangeable Shares") at the exchange ratio of 0.731 Coeur common shares or Canadian Exchangeable Shares for each Wheaton common share exchanged (the "Exchange Ratio"). There is no limit on the number of Wheaton common shares that may be exchanged for Coeur common shares or Canadian Exchangeable Shares. However, the maximum aggregate amount of cash that Coeur will pay to Wheaton shareholders under the Enhanced Coeur Proposal is $570 million. Therefore, elections to receive cash will be subject to proration if Wheaton shareholders elect in the aggregate to receive more than $570 million. Based on the number of issued and outstanding Wheaton common shares on May 27, 2004, the date that Coeur first announced its proposal, if all Wheaton shareholders elect to receive cash for their Wheaton common shares, shareholders will receive $1.00 in cash per Wheaton common share and 0.577 Coeur common shares or Canadian Exchangeable Shares. If less than all Wheaton shareholders elect the cash option, Wheaton shareholders will receive up to $5.00 per Wheaton common share in cash (subject to proration based on the maximum aggregate cash consideration of $570 million).

(2) Based on Coeur's closing share price on May 27, 2004 and a Canadian/U.S. dollar exchange rate of 1.3597 on May 27, 2004. In addition, under the Enhanced Coeur Proposal, it is contemplated that warrant and option holders of Wheaton will be entitled to receive an equivalent value of Coeur warrants and options based on the Exchange Ratio. THE ENHANCED COEUR PROPOSAL IS SUBJECT TO THE LAWFUL TERMINATION OF THE ARRANGEMENT AGREEMENT BETWEEN IAMGOLD CORPORATION AND WHEATON DATED APRIL 23, 2004 IN RESPECT OF THE IAMGOLD PROPOSAL TO BE VOTED ON BY WHEATON SHAREHOLDERS AT THE NEW MEETING. Coeur believes that the Enhanced Coeur Proposal is superior to the IAMGold Proposal and therefore recommends that you VOTE AGAINST the IAMGold Arrangement Resolution. Based on closing share prices on May 27, 2004, the Enhanced Coeur Proposal will provide Wheaton shareholders a total value of approximately $5.00 for each Wheaton common share, of which at least $1.00 is cash. The Enhanced Coeur Proposal represents: - A premium of $0.94 for each Wheaton common share over the IAMGold Proposal based on closing share prices on May 27, 2004. - An increase of approximately 11% over Coeur's initial proposal that was announced on May 27, 2004. - A premium of 26% to Wheaton's closing share price on May 27, 2004. - An opportunity for Wheaton shareholders to receive 23% of the consideration (based on Coeur's closing share price on June 18, 2004) for their Wheaton common shares in cash even if all Wheaton shareholders choose to receive cash. In contrast, the IAMGold Proposal offers Wheaton shareholders: - No cash whatsoever. - Less total value. - Less growth. - Substantially less trading liquidity. - No operating synergies. - No management operational expertise.

(2) Based on the four-month period prior to May 27, 2004. The cash component of the Enhanced Coeur Proposal will be financed by available cash and a commitment letter between Coeur and a major international investment bank. The commitment letter provides that Coeur will issue to the investment bank up to US$225 million of contingent convertible senior notes, with an option to purchase an additional US$50 million of notes. The notes will have a 2% coupon and other terms substantially similar to the terms of Coeur's 1.25% convertible senior notes due 2024. Coeur has agreed to pay to the investment bank a customary bridge financing fee in connection with this financing. Coeur will issue the notes to the bank, and the bank will pay the purchase price of the notes to Coeur, in each case into an escrow account pending the closing of a combination between Coeur and Wheaton. If a combination of Coeur and Wheaton does not occur, Coeur and the investment bank will terminate and unwind this financing.

The merger of Wheaton and Coeur will create the fourth largest North American precious metals company, enhance Coeur's position as the world's largest primary silver producer, and create a top 10 global gold producer with among the lowest cash costs in the industry. The combination will bring together Coeur's wholly owned mines and operating expertise in South America with Wheaton's properties in South America. Based upon a preliminary review of Wheaton's publicly available information, Coeur anticipates that a combination of Coeur and Wheaton will achieve cost savings of US$8 - 10 million. The combined company, a totally unhedged precious metals producer, will have a strong balance sheet, increased financial flexibility, and enhanced trading liquidity on both the NYSE and TSX, providing excellent value to both Wheaton and Coeur shareholders. Simply put, a combination of Wheaton and Coeur has the advantage of superior operating expertise and will result in superior value, growth and liquidity benefiting the shareholders of Wheaton and Coeur. COEUR IS SEEKING TO PURSUE ITS SUPERIOR PROPOSAL WITH THE SUPPORT OF THE WHEATON BOARD Coeur wishes to complete a friendly plan of arrangement to effect the combination of Coeur and Wheaton with the full support of the board of directors and management of Wheaton. Coeur has demonstrated its desire to work with the board of directors and management of Wheaton by the following measures: - COEUR ARRANGEMENT AGREEMENT TO CONTAIN SUBSTANTIALLY THE SAME TERMS AS THE IAMGOLD ARRANGEMENT. In order to minimize the amount of analysis required by the Wheaton board of directors, the Enhanced Coeur Proposal contemplates the consummation of an arrangement agreement setting forth detailed terms and provisions of the Enhanced Coeur Proposal, in form and substance substantially the same as the amended and restated arrangement agreement between Wheaton and IAMGold Corporation dated as of April 23, 2004 (the "IAMGold Arrangement Agreement"). Coeur forwarded a form of arrangement agreement to Wheaton's legal counsel on May 28, 2004. - OPEN COMMUNICATION ENCOURAGED. Coeur's management team has repeatedly announced its desire to meet with Wheaton's board of directors and management to discuss in detail its proposals. In the face of this, Wheaton's board of directors provided Coeur with only a token meeting lasting 30 minutes on Sunday, June 6, 2004, to make a presentation. The Wheaton board of directors rejected the Coeur proposal less than three hours later without any further discussion and without requesting any information. Coeur remains open to speaking directly with the board of directors, the recently formed special committee of the board of directors and management of Wheaton to discuss the Enhanced Coeur Proposal. - DUE DILIGENCE ON COEUR INVITED. Coeur has invited Wheaton's board of directors and its advisors to conduct due diligence investigations on Coeur's assets in order to better understand the compelling rationale and superior value of a business combination between Coeur and Wheaton. To date, Wheaton has not taken Coeur up on this offer.

The Enhanced Coeur Proposal is superior to the IAMGold Proposal. While it is Coeur's desire to complete a friendly business combination with Wheaton by way of a plan of arrangement, if the Wheaton board of directors continues to refuse to negotiate with Coeur, Coeur will consider other transaction alternatives, including making a formal offer directly to the shareholders of Wheaton. IMPLEMENTING THE ENHANCED COEUR PROPOSAL THE COMBINATION OF COEUR AND WHEATON In order to implement the Enhanced Coeur Proposal it is contemplated that an arrangement agreement (the "Coeur Arrangement Agreement") will be entered into under which Coeur and Wheaton will complete a plan of arrangement under section 182 of the Business Corporations Act (Ontario) (the "Coeur Arrangement"). Coeur currently contemplates that the Coeur Arrangement will include a new parent holding company to be formed by Coeur. All of the existing shares of Coeur will be converted into a like number of shares of this new holding company. Because this new holding company will replace Coeur as the ultimate parent entity and will have publicly traded stock, this new holding company will issue common shares in the plan of arrangement. In this Circular, the description of the issuance of Coeur shares under the Enhanced Coeur Proposal refers to the issuance of a like number of shares of this new Coeur holding company. The Coeur Arrangement Agreement will contain substantially the same representations, warranties, covenants and terms and conditions as the IAMGold Arrangement Agreement. TREATMENT OF WHEATON WARRANTS AND WHEATON OPTIONS UNDER THE COEUR ARRANGEMENT It is contemplated that the Coeur Arrangement Agreement will provide that each holder of an option to purchase Wheaton common shares and each holder of a Wheaton common share purchase warrant will be entitled to receive an equivalent value of Coeur warrants and options based on the Exchange Ratio. CONDITIONS TO THE COEUR ARRANGEMENT The obligations of Coeur and Wheaton to complete the Coeur Arrangement will be standard for a plan of arrangement and will be similar to those contemplated by the IAMGold Arrangement. NON-SOLICITATION PROVISIONS UNDER THE COEUR ARRANGEMENT It is contemplated that the Coeur Arrangement Agreement will contain non-solicitation provisions that are standard for a plan of arrangement and similar to those contemplated by the IAMGold Arrangement Agreement. SUPERIOR PROPOSALS UNDER THE COEUR ARRANGEMENT It is Coeur's intention to ensure that the definition of superior proposal used in the Coeur Arrangement Agreement will be that which is typically seen in business combinations and will not YOUR VOTE IS IMPORTANT - PLEASE SUBMIT YOUR GREEN PROXY TODAY IF YOU REQUIRE ASSISTANCE PLEASE CALL MACKENZIE PARTNERS, INC.--(212) 929-5500 (collect) or 1-800-322-2885 (toll free) -8- follow the definition used in the IAMGold Arrangement Agreement, which Coeur feels fetters the ability of a board of directors to consider a clearly superior third party proposal. Accordingly, the definition of superior proposal will allow the board of directors of either Wheaton or Coeur to exercise their fiduciary duties as directors to enter into negotiations with a third party that has put forward a proposal that will result in a transaction more favourable to Wheaton shareholders or Coeur shareholders, as the case may be, than the transaction contemplated by the proposed Coeur Arrangement Agreement. TERMINATION AND TERMINATION FEES UNDER THE COEUR ARRANGEMENT It is contemplated that the termination and termination fee provisions of the Coeur Arrangement Agreement will be the same as, or similar to, those contained in the IAMGold Arrangement Agreement. INFORMATION ABOUT COEUR D'ALENE MINES CORPORATION Coeur was incorporated in Idaho, U.S.A. in 1928. The address of Coeur is 505 Front Avenue, P.O. Box I, Coeur d'Alene, Idaho 83816-0316. The common stock of Coeur trades on the New York Stock Exchange under the symbol CDE. As at June 18, 2004 the market capitalization of Coeur was US$907 million. Additional information about Coeur is available in Coeur's filings with the United States Securities and Exchange Commission available at www.sec.gov/edgar.html. Coeur is the world's largest primary silver producer and a growing low-cost gold producer and is engaged in the exploration, development and operation of silver and gold mining properties located in Chile, Argentina, the United States and Bolivia. In 2003, Coeur produced approximately 14.2 million ounces of silver and 119,500 ounces of gold. In 2004, Coeur expects that its production will increase to 14.5 million ounces of silver and 133,000 ounces of gold. Coeur's principal silver and gold mines are located in southern Chile (the Cerro Bayo Mine), Argentina (the Martha Mine), Nevada (the Rochester Mine) and the Silver Valley region of northern Idaho (the Galena Mine). In addition, Coeur owns or leases, either directly or through its subsidiaries, silver and gold development projects in Bolivia (the San Bartolome silver project) and in Alaska (the Kensington gold project). These development projects are at the final feasibility stage and are expected to nearly double Coeur's gold production and increase its silver production by over 50% in the next three years. Coeur also controls strategic properties with exploration potential close to its existing mine operations. Coeur is in a strong financial position, with US$235 million in cash and no net debt. Between January 1, 2003 through May 27, 2004, Coeur's share price on the New York Stock Exchange increased 157%, making Coeur one of the best performers in the precious metals sector.

Coeur has engaged the services of MacKenzie Partners, Inc. and CIBC World Markets Inc. to assist them in the solicitation of proxies. MacKenzie Partners, Inc. will receive a minimum fee of US$150,000 in connection with the services rendered for and on behalf of Coeur and will also be reimbursed for certain out-of-pocket expenses incurred by it.

RECORD DATE AND VOTING SHARES Wheaton has announced that the record date for determining shareholders entitled to notice of the New Meeting is April 28, 2004 (the "Record Date"). For purposes of the New Meeting, Wheaton has prepared a list of shareholders who were registered on its records or the records of its transfer agent, CIBC Mellon Trust Company, at the close of business on the Record Date. Each shareholder named on the list is entitled, upon providing satisfactory identification, to vote the common shares of Wheaton shown in such list as being held by such shareholder (other than common shares for which a proxy has been given and not revoked). To the extent that a Wheaton shareholder has transferred Wheaton common shares after the Record Date and the transferee of such Wheaton common shares produces a properly endorsed certificate for such Wheaton common shares or otherwise establishes that the transferee owns them and demands, not later than 10 days before the New Meeting, that the transferee's name be included in the list of Wheaton shareholders entitled to vote at the New Meeting, in which case the transferee will be entitled to vote such Wheaton common shares at the New Meeting. APPOINTMENT AND REVOCATION OF PROXIES The persons named as proxyholders in the accompanying GREEN proxy are Mitchell Krebs, Tony Ebersole and Steven Balet. A shareholder wishing to appoint some other person (who need not be a Wheaton shareholder) to represent him, her or it at the New Meeting has the right to do so, either by inserting such person's name in the blank space provided in the GREEN proxy or by completing another proper form of proxy. IN ORDER TO ENSURE THAT THEIR PROXIES CAN BE USED AT THE NEW MEETING, SHAREHOLDERS SHOULD CAREFULLY COMPLETE AND SIGN THEIR GREEN PROXY AND FAX OR MAIL THEIR GREEN PROXY TO THE FAX NUMBER OR ADDRESS SHOWN ON THE REVERSE OF THE GREEN PROXY.

YOU MAY REVOKE A PROXY ALREADY GIVEN PURSUANT TO THE SOLICITATION OF PROXIES BY THE MANAGEMENT OF WHEATON PURSUANT TO THE CIRCULAR. A registered shareholder who has given a proxy may revoke such proxy by: (i) completing and signing a valid proxy bearing a later date and returning it to Mackenzie Partners, Inc. as described above; or (ii) depositing an instrument in writing executed by the shareholder or his, her or its attorney authorized in writing, and if the shareholder is a corporation, by a duly authorized officer or attorney of such corporation either: (a) at the registered office of Wheaton at any time up to and including the last business day preceding the day of the New Meeting, or any adjournment or postponement thereof, at which the proxy is to be used; or (b) with the chair of the New Meeting on the day of the New Meeting or any adjournment or postponement thereof; or (iii) in any other manner permitted by law. REGISTERED SHAREHOLDERS If you are a registered Wheaton shareholder, you should follow the procedures set out in the GREEN proxy and as set out below. Even if you have already submitted the proxy form that accompanied the Wheaton Proxy Circular, as described above you may submit a GREEN proxy form thereby automatically revoking the proxy that you have previously submitted. In order to VOTE AGAINST the IAMGold Arrangement Resolution put forth in the Wheaton Proxy Circular, you should do the following: 1. Complete the GREEN proxy by marking "VOTE AGAINST" the special resolution to approve the arrangement under section 182 of the Business Corporations Act (Ontario) involving IAMGold Corporation, 2045230 Ontario Inc. and Wheaton. 2. Sign and date the GREEN proxy and fax it back to the number indicated on the GREEN proxy. If faxing is not an option, please use the pre-paid envelope enclosed with the GREEN proxy. NON-REGISTERED SHAREHOLDERS Only registered Wheaton shareholders or the persons they appoint as their proxy holders are permitted to vote at the New Meeting. However, in many cases, shares beneficially owned by a person (a "Non-Registered Holder") are registered either: (i) in the name of an intermediary (an "Intermediary") that the Non-Registered Holder deals with in respect of the shares of Wheaton (Intermediaries include, among others, YOUR VOTE IS IMPORTANT - PLEASE SUBMIT YOUR GREEN PROXY TODAY IF YOU REQUIRE ASSISTANCE PLEASE CALL MACKENZIE PARTNERS, INC.--(212) 929-5500 (collect) or 1-800-322-2885 (toll free) -13- banks, trust companies, securities dealers or brokers and trustees or administrators of self-administered RRSPs, RRIFs, RESPs and similar plans); or (ii) in the name of a depository (such as The Canadian Depository for Securities Limited or the Depository Trust Company) of which the Intermediary is a participant. In accordance with the requirements of National Instrument 54-101 Intermediaries are required to forward all meeting materials to Non-Registered Holders. Intermediaries often use service companies to forward the meeting materials to Non-Registered Holders. WITHOUT SPECIFIC INSTRUCTIONS, INTERMEDIARIES ARE PROHIBITED FROM VOTING SHARES FOR THEIR CLIENTS. THEREFORE, NON-REGISTERED HOLDERS WHO WISH TO VOTE AGAINST THE IAMGOLD ARRANGEMENT RESOLUTION SHOULD ENSURE THAT INSTRUCTIONS RESPECTING THE VOTING OF THEIR WHEATON SHARES ARE COMMUNICATED TO THE INTERMEDIARY BY THE APPROPRIATE TIME. A NON-REGISTERED HOLDER CANNOT USE A VOTING INSTRUCTION FORM TO VOTE WHEATON SHARES DIRECTLY AT THE NEW MEETING. VOTING INSTRUCTIONS MUST BE RETURNED TO THE INTERMEDIARY SUFFICIENTLY IN ADVANCE OF THE NEW MEETING TO HAVE THOSE WHEATON SHARES VOTED. Intermediaries often use service companies to forward meeting materials to Non-Registered Holders. Generally, Non-Registered Holders who have not waived the right to receive meeting materials will either: (i) be given a voting instruction form WHICH IS NOT SIGNED BY THE INTERMEDIARY and which, when properly completed and signed by the Non-Registered Holder and RETURNED TO THE INTERMEDIARY OR ITS SERVICE COMPANY, will constitute voting instructions which the Intermediary must follow. Typically, the voting instruction form will consist of a one page pre-printed form. Sometimes, instead of the one page pre-printed form, the voting instruction form will consist of a regular printed proxy form accompanied by a page of instructions which contains a removable label with a bar-code and other information. In order for the form of proxy to validly constitute a voting instruction form, the Non-Registered Holder must remove the label from the instructions and affix it to the form of proxy, properly complete and sign the form of proxy and submit it to the Intermediary or its service company in accordance with the instructions of the Intermediary or its service company; or (ii) be given a form of proxy WHICH HAS ALREADY BEEN SIGNED BY THE INTERMEDIARY (typically by a facsimile, stamped signature), which is restricted as to the number of shares beneficially owned by the Non-Registered Holder but which is otherwise not completed by the Intermediary. Because the Intermediary has already signed the form of proxy, this form of proxy is not required to be signed by the Non-Registered Holder when submitting the proxy. In this case, the Non-Registered Holder who wishes to submit a proxy should properly complete the form of proxy and deposit it with MacKenzie Partners, Inc., 105 Madison Avenue, New York, NY 10016 (fax: (212) 929-0308) with respect to the Wheaton shares. The purpose of these procedures is to permit Non-Registered Holders to direct the voting of the shares of Wheaton they beneficially own. Should a Non-Registered Holder wish to attend and vote at the New Meeting in person (or have another person attend and vote on behalf of the Non-Registered Holder), the Non-Registered Holder should strike out the person's named in the form of proxy and insert the Non-Registered Holder or such other person's name in the blank space provided. IN ANY CASE, NON-REGISTERED HOLDERS SHOULD CAREFULLY FOLLOW THE INSTRUCTIONS OF THEIR YOUR VOTE IS IMPORTANT - PLEASE SUBMIT YOUR GREEN PROXY TODAY IF YOU REQUIRE ASSISTANCE PLEASE CALL MACKENZIE PARTNERS, INC.--(212) 929-5500 (collect) or 1-800-322-2885 (toll free) -14- INTERMEDIARY, INCLUDING THOSE REGARDING WHEN AND WHERE THE PROXY (OR ANY PROXY AUTHORIZATION FORM) IS TO BE DELIVERED. A Non-Registered Holder may revoke a form of proxy or voting instruction form given to an Intermediary at any time by written notice to the Intermediary in accordance with the instructions given to the Non-Registered Holder by its Intermediary. In order to ensure that an Intermediary acts upon a revocation of a proxy authorization form, the written notice should be received by the Intermediary well in advance of the New Meeting.
