Proposal Offers Orko Shareholders Attractive Premium, Superior Value Certainty Due to CAD$100M Cash Component, and Opportunity to Participate in Significant Upside Potential in Combined Company's Shares and Warrants

Combination Diversifies Coeur's Precious Metals Asset Portfolio and Adds Meaningful Growth

COEUR D'ALENE, Idaho--(BUSINESS WIRE)--Feb. 13, 2013-- Coeur d'Alene Mines Corporation (the "Company" or "Coeur") (NYSE: CDE) (TSX: CDM) today confirmed that it has submitted a binding proposal ("Coeur's Proposal") to acquire all of the issued and outstanding common shares of Orko Silver Corp. ("Orko") (TSX VENTURE: OK) in a transaction with a total value of approximately CAD$384 million. Orko today announced that its Board of Directors has unanimously determined, after receiving the advice of its financial and legal advisors, that Coeur's Proposal constitutes a "Superior Proposal" pursuant to its arrangement agreement with First Majestic Silver Corporation ("First Majestic") (FR.TO) (AG) (FMV.F). Orko has provided notice of such determination to First Majestic. Orko also announced that under the arrangement agreement, First Majestic now has five business days, expiring at 11:59 p.m. PST on Tuesday, February 19, 2013, to offer to amend the terms of that agreement to match Coeur's Proposal, failing which Orko will terminate the arrangement agreement with First Majestic and enter into a definitive agreement with Coeur reflecting Coeur's Proposal.

Under the terms of Coeur's Proposal, Orko shareholders may elect to receive in exchange for each Orko share:

• 0.0815 common shares of Coeur ("Coeur Shares") and CAD$0.70 cash and 0.01118 warrants to purchase Coeur shares ("Coeur Warrants");
• 0.1118 Coeur Shares and 0.01118 Coeur Warrants, subject to pro-ration as to the number of Coeur Shares if the total number of Coeur Shares elected by Orko shareholders exceeds approximately 11.6 million; or
• CAD$2.60 in cash and 0.01118 Coeur Warrants, subject to pro-ration as to the amount of cash if the total cash elected by Orko shareholders exceeds CAD$100 million.

If all Orko shareholders were to elect either the all cash (and Coeur Warrants) or the all share (and Coeur Warrants) alternative, each Orko shareholder would receive 0.0815 Coeur Shares and CAD$0.70 in cash, together with 0.01118 Coeur Warrants, for each Orko share.

Based on the closing prices of the shares of each of Coeur, Orko and First Majestic as of February 12, 2013, Coeur's Proposal implies a value of CAD$2.70 per Orko share, which represents a premium of approximately 71% to the unaffected Orko share price on December 14, 2012, the last trading day prior to the announcement of Orko's agreement with First Majestic, and a premium of approximately 25% to the implied value of the consideration offered pursuant to the First Majestic arrangement agreement.

"We are pleased that Orko's Board of Directors unanimously determined that our proposal is superior to the First Majestic offer," said Mitchell J. Krebs, Coeur's President and Chief Executive Officer. "Based upon the substantial cash component of the proposal and the liquidity of Coeur's common shares, we believe our proposal provides Orko shareholders with an attractive premium, superior value certainty, and the opportunity to share in the significant upside potential of the combined entity. We have a demonstrated track record of developing, commissioning and operating large-scale precious metals assets as well as the financial resources necessary to bring Orko's La Preciosa project into production. The combination with Orko will deliver enhanced asset and geographic portfolio diversification and robust growth prospects for our combined shareholder base. We are committed to this strategic combination and look forward to expeditiously executing the proposed agreement."

Strategic Rationale of the Transaction

• Continued Participation in the La Preciosa Project. Orko shareholders, through their ownership of Coeur Shares and Coeur Warrants, would receive a significant premium to the current Orko share price and would also have the opportunity to continue to participate in any future value increases associated with the development and operation of the La Preciosa project, which ranks as one of the world's largest undeveloped primary silver projects.
• Access to the Capabilities of Coeur. With its 80-year operating track record and demonstrated success in developing, commissioning and operating large-scale projects, Coeur has the necessary financial strength, and development and operating experience to bring the La Preciosa project into production. Coeur has successfully built and now operates the San Bartolom� mine in Bolivia (US$238 million capital cost, start-up in 2008), the Palmarejo mine in Mexico (US$353 million capital cost, start-up in 2009) and the Kensington mine in Alaska (US$435 million capital cost, start-up in 2010) and as such Coeur believes it is better equipped than its peers to develop and operate La Preciosa.
• Participation in a Company with Geographically Diverse Projects and Robust Growth Prospects. Orko shareholders would also benefit from having an equity position in a company with greater geographic diversity. At present, Coeur has interests in mining properties located in Mexico, Bolivia, Alaska, Nevada, Australia and Argentina and operates mines in Alaska, Nevada, Mexico and Bolivia. The combination would improve the overall profile of the combined business by further diversifying Coeur's asset mix and by adding a world-class development asset to its portfolio. After closing the proposed transaction, the combined company would have an attractive portfolio of open-pit and underground operations and a robust growth profile. The commodity exposure of the combined entity would be approximately 75% silver and 25% gold.
• Availability of Capital, Strong Cash Flow, and Substantial Production Profile. Coeur has over US$500 million in available liquidity to support mine development and further growth initiatives. In addition, Coeur generates substantial cash flow from its existing portfolio of mines. During the trailing twelve month period ended September 30, 2012, Coeur's Adjusted EBITDA was US$406 million¹. (Net income was $22.5 million for the equivalent period.) In addition, Coeur produced 18.0 million ounces of silver and an all-time high 226,491 ounces of gold for the full year ended December 31, 2012.
• Increased Market Capitalization of Coeur and Liquidity. Coeur is listed on both the New York Stock Exchange and Toronto Stock Exchange and has a market capitalization of more than US$2 billion. Coeur's shares are highly liquid with an average daily trading volume of 1.6 million shares, representing US$38 million on a daily basis over the last twelve months. Coeur's Board of Directors and management are confident that Orko shareholders would effectively view Coeur's share consideration as an equivalent to cash as it would take just seven days to trade the entire share consideration under the proposed transaction.

Coeur's Proposal has been approved by the Coeur Board of Directors and no further corporate or shareholder approvals are required by Coeur to complete the transaction. Coeur's Proposal is not conditional on any financing.

Additional Transaction Details

Each whole Coeur Warrant will be exercisable for one Coeur Share for a period of four years at an exercise price of US$30.00, all subject to adjustment in accordance with the terms of the warrant (the "Coeur Warrants"). While Coeur will use commercially reasonable efforts to register the Coeur Shares issuable on exercise of the Coeur Warrants under applicable United States securities laws and have the Coeur Warrants listed and posted for trading on the Toronto Stock Exchange and New York Stock Exchange, the completion of such registration and listing will not be a condition of closing of the transaction.

In addition, Coeur will use commercially reasonable efforts, subject to compliance with certain Coeur contractual obligations, to make any necessary amendments to permit Orko shareholders who are residents of Canada for purposes of the Income Tax Act (Canada) (other than such Orko shareholders who are exempt from tax thereunder) and who would receive Coeur Shares under Coeur's Proposal to receive, instead of Coeur Shares, shares of a Canadian-incorporated subsidiary of Coeur (the "Exchangeable Shares") that are exchangeable into Coeur Shares to allow such Orko shareholders to receive a tax-deferred roll-over under the Income Tax Act (Canada) to the extent that the non-share consideration received does not exceed the shareholder's cost base for Canadian tax purposes. While Coeur will use commercially reasonable efforts to register the Coeur Shares issuable on exchange of the Exchangeable Shares under applicable United States securities laws, the completion of such registration will not be a condition of closing of the transaction.

Coeur's Proposal contemplates that the Coeur Shares will be issued in a transaction exempt from the registration requirements of the United States Securities Act of 1933, as amended (the "U.S. Securities Act") pursuant to Section 3(a)(10) of the U.S. Securities Act. Consequently, the Coeur Shares, other than Coeur Shares to be issued upon exercise of the Coeur Warrants or the exchange of the Exchangeable Shares, will not be registered under the U.S. Securities Act or under any U.S. state securities laws. This news release shall not constitute an offer to sell or a solicitation of an offer to purchase the Coeur Shares, Coeur Warrants, Exchangeable Shares or any other securities, and shall not constitute an offer, solicitation or sale in any jurisdiction, province or state in which such an offer, solicitation or sale would be unlawful.

Cautionary Note to U.S. Investors-The United States Securities and Exchange Commission permits U.S. mining companies, in their filings with the SEC, to disclose only those mineral deposits that a company can economically and legally extract or produce.

Non-U.S. GAAP Measures

This news release discloses our Adjusted EBITDA, which is a supplemental financial measure not calculated under United States generally accepted accounting principles (U.S. GAAP). We believe that this adjusted measure provides meaningful information to assist management, investors and analysts in understanding our financial results and assessing our prospects for future performance. We believe Adjusted EBITDA is a useful indicator of our recurring operations because it excludes items that may not be indicative of, or are unrelated to our core operating results, and provides a better baseline for analyzing trends in our underlying businesses.
