Silver Standard Reports Impressive Silver Assays From Australia.Business Editors VANCOUVER, British Columbia--(BUSINESS WIRE)--May 12, 2003 Silver Standard Resources Inc. is pleased to report further impressive results from infill in·fill n. 1. The use of vacant land and property within a built-up area for further construction or development, especially as part of a neighborhood preservation or limited growth program. 2. drilling at its wholly-owned Bowdens silver project located in New South Wales New South Wales, state (1991 pop. 5,164,549), 309,443 sq mi (801,457 sq km), SE Australia. It is bounded on the E by the Pacific Ocean. Sydney is the capital. The other principal urban centers are Newcastle, Wagga Wagga, Lismore, Wollongong, and Broken Hill. , Australia. The results from 30 reverse circulation drill holes reported here are among the remaining results of a 19,000-meter program that commenced in October 2002 and was recently completed. Most of the holes reported here were located in the Main Zone North area of the flat-lying deposit where earlier, wider-spaced drilling had identified thick sequences of silver mineralization Mineralization The process by which the body uses minerals to build bone structure. Mentioned in: Rickets mineralization, n the bioprecipitation of an inorganic substance. . Other holes were located at Bundarra North and Main Zone South. The results of the 30 drill holes confirm continuity of mineralization between earlier holes, with high-grade High-grade Credit quality of AAA or AA. high-grade Of, relating to, or being a bond with little risk of default on the part of the issuer. High-grade is usually reserved for bonds rated AAA or AA by the rating services. silver values locally over significant intervals. The best results in the Main Zone North are in holes BGR-286, 280 and 278. BGR BGR Bundesanstalt für Geowissenschaften und Rohstoffe (in Federal Republic of Germany) BGR Bulgaria (ISO Country code) BGR Blue Green Red (uncommon variant of RGB) 286 and 280 are 200 meters apart and, together with other holes drilled in the vicinity, underline underline an animal's ventral profile; the shape of the belly when viewed from the side, e.g. pendulous, pot-belly, tucked up, gaunt. the potential for increasing the grade (and contained silver) of the Bowdens deposit. BGR-286 intersected 8.1 ounces of silver per ton over 167.3 feet (278 grams of silver per tonne tonne measure of weight or mass; 1 tonne=1000 kg. See also ton. over 51 meters) plus base metal credits and included 30.8 ounces of silver per ton over 32.8 feet (1,056 grams of silver per tonne over 10 meters) plus base metal credits. BGR-280 intersected 8.7 ounces of silver per ton over 118.1 feet (299 grams of silver per tonne over 36 meters) plus base metal credits and BGR-278 intersected 18.0 ounces of silver per ton over 52.5 feet (618 grams of silver per tonne over 16 meters) plus base metal credits, including 90.0 ounces of silver per ton, 4.56% lead and 3.35% zinc zinc, metallic chemical element; symbol Zn; at. no. 30; at. wt. 65.38; m.p. 419.58°C;; b.p. 907°C;; sp. gr. 7.133 at 25°C;; valence +2. Zinc is a lustrous bluish-white metal. It is found in Group 12 of the periodic table. over 6.6 feet (3,085 grams of silver per tonne over 2.0 meters). BGR-299, a single infill hole in the Main Zone South, also intersected good values over significant dimensions. This hole assayed 1.8 ounces of silver per ton and 1.0% zinc over 232.9 feet (63 grams of silver per tonne over 71 meters). The best result from Bundarra North is in BGR-301 which intersected 3.8 ounces of silver per ton over 42.7 feet (132 grams of silver per tonne over 13 meters) as well as deeper zones of lower grade mineralisation which include 1.1 ounces of silver per ton over 173.9 feet (37 grams of silver per tonne over 53 meters) plus base metal credits. See the accompanying table for further results and visit http://www.silver-standard.com/s/News-2002.asp to view the drill hole plan. The deposit is open to the north and northwest where mineralization appears to extend under a hill that currently inhibits reverse circulation drilling with available equipment. Results from a further 12 holes are pending and will be reported as assaying is finalized See finalization. . Upon receipt of all assay data, the company plans to complete a new block model resource calculation. In addition to the program at Bowdens, Silver Standard is presently drilling at its Challacollo property in Chile and at its La Valenciana property in the State of Durango, Mexico. Silver Standard is a significant silver resource company with projects in Australia, Argentina, Chile, Mexico, the United States United States, officially United States of America, republic (2005 est. pop. 295,734,000), 3,539,227 sq mi (9,166,598 sq km), North America. The United States is the world's third largest country in population and the fourth largest country in area. and Canada. The company's assets include measured and indicated resources of 288.8 million ounces of silver and 1.1 million ounces of gold, plus inferred resources of 356.2 million ounces of silver and 1.1 million ounces of gold. Silver Standard is well financed and actively advancing its portfolio with drill programs now under way and new acquisitions under investigation.
