VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 08/25/08 -- Silver Standard Resources Inc. (TSX: SSO)(NASDAQ: SSRI) reports a further increase in silver and base metal resources at the Pitarrilla project in Durango State, Mexico. In July 2008, Silver Standard announced a 14% increase in total silver resources for Pitarrilla estimated by P&E Mining Consultants Inc. ("P&E") of Brampton, Ontario. A review of the P&E resource model as part of the reserve estimation for the pre-feasibility study currently underway for Pitarrilla determined that the silver-equivalent cutoff may have understated silver and base metal resources. As a consequence, P&E has undertaken an internal review of their silver-equivalent cutoff, resource model and associated resource estimate and determined that total silver resources at Pitarrilla have increased by a further 9.5%.

---------------------------------------------------------------------
The above block model resource estimate is based on a cut-off grade of 20
grams of silver-equivalent per tonne for open pit resources and a cut-off
grade of 65 grams of silver-equivalent per tonne for underground resources
for Breccia Ridge. Silver-equivalent grades were calculated using US$11/oz
silver, US$1.05/lb zinc, US$0.75/lb lead and US$2.00/lb copper. The cut-off
grade for all other zones at Pitarrilla is 40 grams of silver per tonne.

All of the increase in resources is at the Breccia Ridge Zone, with measured and indicated silver resources increasing by 42.6 million ounces and inferred silver resources increasing by 20.3 million ounces, an increase of 16% in total resources from July 2008.

The above block model resource estimate is based on a cut-off grade of 20
grams of silver-equivalent per tonne for open pit resources and a cut-off
grade of 65 grams of silver-equivalent per tonne for underground resources.
Silver-equivalent grades were calculated using US$11/oz silver, US$1.05/lb
zinc, US$0.75/lb lead and US$2.00/lb copper.

The majority of the increase in measured and indicated resources is associated with the higher grade, underground resource. Measured and indicated silver resources for the higher grade underground resource now total 193.6 million ounces, an increase of 40.3 million ounces or 26% from July 2008. In addition, the underground resource tonnage has increased from 40 million tonnes to 86 million tonnes.
