Coeur Mining to Acquire Paramount Gold and Silver

Paramount's High-Grade Don Ese Deposit Expected to Provide Low-Capital, High-Margin, Near-Term Source of Future Production to Supplement Production from Coeur's Palmarejo Mine

Substantial Development and Operating Synergies with Coeur's Palmarejo Operation Anticipated to Create Significant Long-Term Value

Don Ese and Guadalupe Combined Expected to Produce an Average of Approximately Six Million Ounces of Silver and 110,000 Ounces of Gold Annually over the Next Eight Years

CHICAGO, Dec. 17, 2014 (GLOBE NEWSWIRE) -- Coeur Mining Inc. ("Coeur" or the "Company") (NYSE:CDE) today announced it has entered into a merger agreement under which Coeur has agreed to acquire all of the outstanding shares of Paramount Gold and Silver Corp. ("Paramount") (NYSE MKT:PZG) and (TSX:PZG) in an all-stock transaction valued at $146 million. Immediately prior to completion of the merger, Paramount will spin-off to its existing stockholders a separate, publicly traded company, expected to be named Paramount Nevada Gold Corp. ("SpinCo"), a subsidiary that owns the Sleeper Gold Project and other assets in Nevada. As part of the transaction, Coeur will provide $10 million in cash to SpinCo and receive a 4.9% common share interest.

Key Highlights

• Paramount's San Miguel Project (which includes the Don Ese deposit) covers over 121,000 hectares (approximately 299,000 acres) surrounding Coeur's Palmarejo mine complex in Chihuahua, Mexico
• The Don Ese deposit extends across a shared property boundary onto Coeur's land holdings at Palmarejo and is located approximately 800 meters from Coeur's Guadalupe deposit, which is currently being developed
• Don Ese consists of significantly higher grade silver and gold mineralization than Guadalupe, and is not subject to any non-government third-party royalty or stream obligations
• Don Ese represents the southeast extension of Coeur's Independencia structure
• Coeur plans to develop Don Ese by a 1,000 meter decline adjacent to the existing Guadalupe surface infrastructure at an initial cost next year of approximately $15 million, and anticipates initial production from Don Ese by the end of 2015, ramping up to 2,500 tons per day by the end of 2017
• Palmarejo's 6,000 ton-per-day processing facility is expected to have excess capacity as open pit production ends in 2015 and as mining activities transition to Guadalupe. As part of Coeur's diligence on the Don Ese deposit, Coeur anticipates recovery rates of approximately 80% for silver and 95% for gold from the deposit
• Assuming utilization of excess processing facility capacity, Coeur anticipates the combined Don Ese and Guadalupe deposits could produce an average of approximately six million ounces of silver and 110,000 ounces of gold annually over the next eight years
• Coeur has identified significant additional exploration potential on other high-grade structures near the shared property boundary
• Paramount's San Miguel project also contains several lower grade deposits which could benefit from cost savings associated with Palmarejo's existing infrastructure and provides Coeur stockholders with optionality on any future increases in silver and gold prices

Mitchell J. Krebs, Coeur's President and Chief Executive Officer said, "By adding Paramount's San Miguel Project and particularly the Don Ese deposit to the ongoing mining activities at our Guadalupe deposit, Palmarejo will be well-positioned to remain one of the world's top producing silver and gold mines with significantly higher grades and lower costs. Paramount's Mexican assets strengthen the long‐term viability of Palmarejo throughout the price cycle and enhance Coeur's growth profile. We expect the transaction to lower our overall unit costs, improve our free cash flow in the current metal price environment, and provide near-term growth while preserving our liquidity."

Under the terms of the merger agreement:

• Paramount stockholders will receive: 0.2016 Coeur shares per Paramount share, equal to $0.90 based on Coeur's 20-day volume weighted average price ("VWAP") of $4.47 as of December 16, 2014, representing a premium of 19.8% to Paramount's 20-day VWAP of $0.75; and
• Paramount will spin off its non-Mexican assets and liabilities and $10 million in cash (to be provided by Coeur as part of the transaction) to SpinCo, which is anticipated to apply to list its shares on the NYSE MKT or the Toronto Stock Exchange. Paramount stockholders will receive a pro rata share of the 95.1% of SpinCo shares to be distributed to Paramount stockholders.

The exchange of Paramount securities for shares of Coeur common stock is anticipated to be a non-recognition transaction for U.S. income tax purposes.

Upon closing of the transaction, it is projected that Coeur will issue approximately 32.7 million shares of common stock to Paramount stockholders. Existing Coeur stockholders will own approximately 76% of the combined entity's outstanding shares and Paramount stockholders will own the remaining approximately 24%.

In a separate transaction not conditioned on the successful acquisition of Paramount by Coeur, Coeur has paid $5.25 million for a 0.7% net smelter returns royalty from Paramount's San Miguel project.

Additional Information Regarding Mineral Properties

Reserves, Resources and Mineralized Material

Coeur Mining Inc. is subject to the reporting requirements of the Exchange Act and applicable Canadian securities laws, and as a result we report our mineral reserves according to two different standards. Canadian reporting requirements for disclosure of mineral properties are governed by National Instrument 43-101 Standards of Disclosure for Mineral Projects ("NI 43-101"). The definitions of NI 43-101 are adopted from those given by the Canadian Institute of Mining, Metallurgy and Petroleum. U.S. reporting requirements, however, are governed by the SEC's Industry Guide 7 (as interpreted by the SEC, "Guide 7"). Both sets of reporting standards have similar goals in terms of conveying an appropriate level of confidence in the disclosures being reported, but embody different approaches and definitions. Under Guide 7, mineralization may not be classified as a "reserve" unless the determination has been made that the mineralization could be economically and legally produced or extracted at the time the reserve determination is made.

In our public filings in Canada and in certain other announcements not filed with the SEC, we disclose measured, indicated and inferred resources, each as defined in NI 43-101, in addition to our mineral reserves. U.S. investors are cautioned that, while the terms "measured mineral resources," "indicated mineral resources" and "inferred mineral resources" are recognized and required by Canadian securities laws, Guide 7 does not recognize them. The estimation of measured resources and indicated resources involve greater uncertainty as to their existence and economic feasibility than the estimation of proven and probable reserves, and therefore U.S. investors are cautioned not to assume that all or any part of measured or indicated resources will ever be converted into Guide 7 compliant reserves.

In this news release, we modify our estimates made in compliance with NI 43-101 to conform to Guide 7 for reporting in the United States. In this news release, we use the term "mineralized material" to describe mineralization in mineral deposits that do not constitute "reserves" under U.S. standards. "Mineralized material" is substantially equivalent to measured and indicated mineral resources (exclusive of reserves) as disclosed for reporting purposes in Canada, except that the SEC only permits issuers to report "mineralized material" in tonnage and average grade without reference to contained ounces. We provide disclosure of mineralized material to allow a means of comparing our projects to those of other companies in the mining industry, many of which are Canadian and report pursuant to NI 43-101, and to comply with applicable disclosure requirements. We caution you not to assume that all or any part of mineralized material will ever be converted into Guide 7 compliant reserves.

Technical Reports and Qualified Person

As required by Canadian securities laws, we hereby notify Canadian investors that the scientific and technical information concerning our mineral projects in this news release have been reviewed and approved by a "qualified person" under NI 43-101, namely our Vice President, Technical Services, W. David Tyler. For a description of the key assumptions, parameters and methods used to estimate mineral reserves included in this news release, as well as data verification procedures and 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, Canadian investors may view technical reports prepared for each of our properties as filed on SEDAR at www.sedar.com. The scientific and technical information in relation to the San Miguel mineralized material is derived from the NI 43-101-compliant Technical Report for San Miguel dated and filed by Paramount August 22, 2014 at sedar.com and Coeur has not independently reviewed or confirmed this information. Neither the technical reports nor the statements of any qualified person filed with the Canadian securities regulatory authorities are included in, or incorporated by reference in, this news release. Because the definitions and standards of NI 43-101 differ from those of Guide 7, investors are cautioned that information contained in reports prepared pursuant to NI 43-101, like the technical reports, may not be comparable to similar information that we can disclose in this news release or the other reports we file with the SEC.

All tons are reported in U.S. standard short ton units. Grades reported are troy ounces per short ton.
