Silver Standard Extends South Ridge Zone at Pitarrilla Silver Project in Mexico; Intercepts High Grade at Depth

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - June 12, 2006) - Silver Standard Resources Inc. (TSX:SSO)(NASDAQ:SSRI) is pleased to report that a step-out vertical hole drilled in the northeast region of the South Ridge Zone at the Pitarrilla silver project in Mexico continues to expand the eastern flank of mineralization. Hole PD-140 was drilled approximately 50 meters to the north of PD-131 and PD-136 reported June 1, 2006.

Highlights of PD-140's mineralization include:

- A massive sulphide intersection of 11.5 feet averaging 26.63% zinc, 1.56% lead and 17.1 ounces of silver per ton (3.5 meters averaging 585.8 grams of silver per tonne), within 61.0 feet averaging 6.62% zinc, 0.41% lead and 4.2 ounces of silver per ton (18.6 meters averaging 144.8 grams of silver per tonne);

- 500.0 feet averaging 1.9 ounces of silver per ton (152.4 meters averaging 65.77 grams of silver per tonne);

These results point to the potential for a massive sulphide feeder system under the volcanic pile which to date has only been tested by a few holes, including the previously reported PD-128 collared 325 meters to the northwest. Drilling continues to intersect a thick sequence of mineralized volcanic material (tuffs, breccias and rhyolitic intrusives) overlying cretaceous sediments. Drilling is continuing with three diamond drill rigs now on site. Kenneth C. McNaughton, M.A.Sc., P.Eng., vice president, exploration, Silver Standard Resources Inc., is the qualified person responsible for the exploration program at Pitarrilla.
