Release: Oropa: High grade rock chip results from new prospect

September 30, 2005 - Oropa is pleased to announce recent rock chip sampling results from the Tambang Tinggi, Tambang Asop, Tambang hitam, Tambang Manunda and Tambang Ubi prospects, located within the company's Pungkut Project, North Sumatra, Indonesia. All prospect occur within a 5km2 area, adjacent to the Trans-Sumatran Highway.

Tambang Asop, Tambang Hitam adn Tambang Manunda prospects appear to be part of a single, low-temperature, low sulphidation epithermal gold system. The tambang Tinggi prospect, located approximately 2km east of Tambang Hitam, is a granodiorite intrusive complex hosting high grade gold/copper/silver mineralisation. Tambang ubi is a gold/copper/silver mineralised skarn deposit exploited during the 1930's by a publicy listed Dutch mining company.

Historical exploration of these prospects is very limited, with oropa commencing its exploration efforts on these targets just 6 weeks ago.

These results confirm the attractiveness of the geological setting for the discovery of mineral resources. The presence of copper-bearing, gold-rich intrusive complexes with spatially associated low temperature, low sulphidation style epithermal gold mineralisation and contact copper/gold skarn mineralisation developed within limestone provides a diverse range, of targets within a relatively confined area.

Oropa is continuing its mapping and sampling programme and will commence initial drill testing these prospects by mid October. (end of release)
