Silver Standard Closes Acquisition of Berenguela Project, Peru

Under the purchase agreement, Silver Standard acquired all of the shares of Sociedad Minera Berenguela S.A., a Peruvian company that holds the rights to the Berenguela project, in consideration of an aggregate payment of US$2.0 million in cash and US$8.0 million in common shares of Silver Standard, and the grant of a 2% net smelter returns royalty on copper capped at US$3.0 million. The common share consideration amounts to 530,504 shares of Silver Standard that are subject to a four-month hold period expiring on May 13, 2006.

Prior to signing the purchase agreement, Silver Standard held an option to acquire all of the property's silver resources by paying US$0.06 per ounce for the defined silver resource and US$0.10 per ounce for all additional silver resources delineated on the property. Under the purchase agreement, Silver Standard has acquired the entire project for US$0.11 per ounce of silver resources, which includes the project's significant copper resources. With the acquisition, Silver Standard controls the direction of the project, allowing it to focus on maximizing the value and potential of the project's silver resources with the integral support of the project's copper resources.

In August 2005, James A. McCrea, P.Geo., (an independent Qualified Person) prepared for Silver Standard a resource estimate for the Berenguela project in accordance with Canada's National Instrument 43-101 (see news release 05-16, September 6, 2005) which is summarized in the following table based on a cut-off grade of 50 grams of silver per tonne:

Cautionary note to U.S. investors concerning disclosure of estimates of mineral resources, contained ounces of silver and contained pounds of copper: The terms "measured resource", "indicated resource" and "inferred resource" used in this news release are Canadian geological and mining terms as defined in accordance with National Instrument 43-101, Standards of Disclosure for Mineral Projects under the guidelines set out in the Canadian Institute of Mining, Metallurgy and Petroleum (the "CIM") Standards on Mineral Resources and Mineral Reserves, adopted by the CIM Council on August 20, 2000 as may be amended from time to time by the CIM. We advise U.S. investors that while such terms are recognized and permitted under Canadian regulations, the SEC does not recognize them. U.S. investors are cautioned not to assume that any part or all of the mineral deposits in the indicated category will ever be converted into reserves. "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 feasibility or other economic studies. U.S. investors are cautioned not to assume that any part or all of an inferred resource exists, or is economically or legally mineable.

Disclosure of silver resources expressed in ounces and copper resources expressed in pounds in the mineral resource category in this news release is in compliance with National Instrument 43-101, but does not meet the requirements of Industry Guide 7, Description of Property by Issuers Engaged or to be Engaged in Significant Mining Operations, of the SEC, which will accept only the disclosure of tonnage and grade estimates for non-reserve mineralization.
