	You are being asked to consider and vote upon 3 proposals:

1.	Increase the authorized shares of Coeur common stock from 500,000,000 to 750,000,000 in order to provide sufficient shares to issue to Bolnisi and Palmarejo shareholders in the transactions.
2.	Authorize the issuance of shares of Coeur common stock to Bolnisi and Palmarejo’s shareholders.
3.	The adjournment or postponement of the special meeting, if necessary or appropriate, to solicit additional proxies if there are insufficient votes at the time of the special meeting to adopt the above two proposals.

Q:	As a shareholder, how will I benefit from this merger?
	Coeur’s board of directors unanimously believes that the transactions are in the best interests of Coeur and its shareholders, because the combined company will bethe world’s leading primary silver companyin terms of annual silver production and low production costs (once the Palmarejo Project commences operations), expected growth rate of production over the next two years, and exploration potential, along with a leading silver resource base. Coeur will also be geographically diversified, with mining operations in North America, South America and Australia, ranging from exploration stage properties to development and operating properties. Coeur will remain highly leveraged to commodity prices with unhedged production and be one of the world’s most liquid publicly-traded silver mining companies with listings on the NYSE and the TSX. Coeur’s financial flexibility, large cash position, and balance sheet strength, will enhance its access to capital markets.

The technical reports have been prepared in accordance with National Instrument 43-101 and are available for review on SEDAR.

Cautionary Statements:

This presentation contains forward-looking statements within the meaning of securities legislation in the United States and Canada including statements regarding a possible transaction and anticipated operating results. Such statements are subject to numerous assumptions and uncertainties, many of which are outside Coeur’s control. Operating, exploration and other statements in this presentation are based on information that Coeur believes is reasonable, but involve significant uncertainties affecting the business of Coeur, including, but not limited to, future gold and silver prices, costs, ore grades, estimation of gold and silver reserves, mining and processing conditions, construction schedules, currency exchange rates, and the completion and/or updating of mining feasibility studies, changes that could result from future acquisitions of new mining properties or businesses, the risks and hazards inherent in the mining business (including environmental hazards, industrial accidents, weather or geologically related conditions), regulatory and permitting matters, risks inherent in the ownership and operation of, or investment in, mining properties or businesses in foreign countries, as well as other uncertainties and risk factors set out in filings made from time to time with the SEC and the Ontario Securities Commission, including, without limitation, Coeur’s reports on Form 10-K and Form 10-Q. As disclosed in this presentation, there are risks that the parties will not proceed with the transaction, that the ultimate terms of the transaction will differ from those that currently are contemplated, and that the results, developments and timetables could vary significantly from the estimates presented. Readers are cautioned not to put undue reliance on forward-looking statements. Coeur disclaims any intent or obligation to update publicly such forward-looking statements, whether as a result of new information, future events or otherwise. Additionally Coeur undertakes no obligation to comment on analyses, expectations or statements made by third parties in respect of Coeur, its financial or operating results or its securities or the possible transaction.

Donald J. Birak, Coeur’s Senior Vice President of Exploration, is the qualified person responsible for the preparation or supervision of the scientific and technical information in this document. For a description of the key assumptions, parameters and methods used to estimate mineral reserves and resources, as well as a general discussion of the extent to which the estimates may be affected by any known environmental, permitting, legal, title, taxation, socio-political, marketing or other relevant factors, please see the Technical Reports for each of Rochester, Cerro Bayo, Martha, san Bartolome, Kensington, Endeavor and Broken Hill projects as filed on SEDAR at (www.sedar.com). For a description of the key assumptions, parameters and methods used to estimate mineral resources for the Palmarejo project, please see the Technical Reports as filed on SEDAR at (www.sedar.com).

This presentation uses the terms ‘Measured”, “Indicated” and “Inferred“ Resources. U.S. investors are advised that while such terms are recognized and required by Canadian regulations, the Securities and Exchange Commission does not recognise them. “Inferred Resources” have a great amount of uncertainty as to their existence and as to their potential economic and legal feasibility. It cannot be assumed that all or any part of an inferred resource will ever be upgraded to a higher category.

The definitions of proven and probable mineral reserves under Canadian National Instrument 43-101 are substantially identical to the definitions of such ore reserves under Guide 7 of the SEC’s Securities Act Industry Guides. Mineral resources are in addition to mineral reserves and have not demonstrated economic viability.

Under Canadian rules, estimates of Inferred Resources may not form the basis of a pre-feasibility or feasibility study. U.S. investors are cautioned not to assume that all or any part of Measured or Indicated Resources will ever be converted into reserves. U.S. investors are also cautioned not to assume that all or any part of an Inferred Mineral Resource exists, or is potentially economical or legally mineable.
