Paramount Gold and Silver Expects Results From Preliminary Economic Assesment of its Nevada Sleeper Gold Project in July

Marketwired

WINNEMUCCA, NEVADA--(Marketwire -06/25/12)- Paramount Gold and Silver Corp. (PZG)(PZG)(PZG.TO)(P6G.F)(WKN:A0HGKQ) ("Paramount") reported today that it expects results from the NI 43-101-compliant Preliminary Economic Assessment (PEA) of its 100%-owned Sleeper Gold Project to be released in July, 2012. In accordance with NI 43-101, Paramount will file a technical report supporting the disclosure of the PEA within 45 days after the results are released.

The Sleeper Gold Project is located off a main highway about 25 miles from the town of Winnemucca, Nevada. Acquired by Paramount in 2010, the project area includes the original Sleeper high-grade open pit mine operated by Amax Gold from 1986 to 1996 as well as staked and purchased claims stretching south down trend to Newmont`s Sandman project.

The PEA is being prepared by Scott E. Wilson Consulting Inc. of Denver, Colorado (www.wilsonmining.com). Scott E. Wilson recently engineered the successful re-start of the Hycroft Gold Mine in Nevada, a project with similarities to Sleeper, owned by Allied Nevada Gold Corp. Scott E. Wilson will provide overall design and estimates of capital and operating costs as well as project economics. The PEA will incorporate the mineral resource estimate prepared by SRK Consulting (www.SRK.com) and released on September 13, 2011. This resource estimate will be updated by Scott E. Wilson to include the addition of a mineral resource estimate for the large dumps and some of the tailings remaining on the property after closure of the original Sleeper Mine as well as the results from drilling completed after the SRK estimate. The PEA will also incorporate metallurgical test work and process alternatives prepared by Tetra Tech (www.tetratech.com) of Elko, Nevada as well as geotechnical and water management consulting by BGC Engineering (www.bgcengineering.com) of Vancouver, Canada.

SRK estimated that the Sleeper Gold Project contains an in situ measured and indicated resource of 2.6 million ounces of gold and 25.3 million ounces of silver and an additional inferred resource of 1.1 million ounces of gold and 8.2 million ounces of silver using a cut-off grade of 0.20 grams of gold per tonne (g/T) for oxide and alluvial material and 0.25 grams per tonne (g/T) for sulfide material. (See tables below for details.) Subsequent drilling in 2011 discovered the new PAD zone beneath the old heap leach pads and extended both the Facilities zone and the Wood Vein zone, returning intercepts comparable to the high grades exploited in the historical Sleeper vein. These results are expected to increase the project`s mineral resource estimate. Reports from Amax Gold, the Sleeper Mine`s original operator, state that about 66 million tonnes of waste rock were extracted during mining of which an estimated 54 million tonnes were placed on three dumps. Systematic drilling and metallurgical testing of this material and some of the property`s historic tailings are expected to make a further addition to the project`s mineral resources in the PEA.

Cautionary Note to U.S. Investors Concerning Estimates of Measured &Indicated and Inferred Resources

This news release uses the terms "measured and indicated resources" and "inferred resources". We advise U.S. investors that while these terms are defined in, and permitted by, Canadian regulations, these terms are not defined terms under SEC Industry Guide 7 and not normally permitted to be used in reports and registration statements filed with the SEC. "Inferred resources" have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates of inferred mineral resources may not form the basis of a feasibility study or prefeasibility studies, except in rare cases. The SEC normally only permits issuers to report mineralization that does not constitute SEC Industry Guide 7 compliant "reserves", as in-place tonnage and grade without reference to unit measures. U.S. investors are cautioned not to assume that any part or all of mineral deposits in this category will ever be converted into reserves. U.S. investors are cautioned not to assume that any part or all of an inferred resource exists or is economically or legally minable
