Bedrock Gold Discovery - Indian River Project

    Vancouver, BC, September 16, 2004 --/24-7PressRelease.com /-- John H. McAdam, President of Boulder Mining Corporation (TSX V:BDR) and John Brock, President of Western Prospector Group Ltd. (TSX V:WNP) report that a drill sample from one of the holes on the Indian River Gold Project yielded a high number (1601) of gold grains. Whereas the number of gold grains is not unexpected, the form of the grains is highly unusual. Unlike typical gold grains in alluvial deposits, approximately 80% of the grains recovered and studied by Overburden Drilling Management are pristine delicate grains. Such delicate gold grains cannot survive transportation in an alluvial environment intact and so it is concluded that these gold grains are in situ. Therefore, It is believed this hole drilled into gold mineralization in the bedrock.

Overburden Drilling Management recovered these gold grains by tabling techniques, which extracts only particles that have been liberated from the host rock. Therefore there is likely to be more gold contained in the overall sample. In light of the above, and given the sample straddled the gravel-bedrock interface the grade of the bedrock portion cannot yet be determined. A sample of bedrock core below this intersection was archived and it will be sent out for assay. The bedrock is about 10 metres below surface.

The fineness of the pristine gold is around 900 being somewhat higher than is normal in Indian River alluvial gold grains indicating a new or different local source of gold. The recovery of heavy minerals from the pitting and drilling programs has also provided additional surprises, including the presence of relatively undamaged galena, pyrite and malachite minerals which were found in several different locations across the property. The presence of these minerals suggests there may be a local hydrothermal mineralizing event for containing both gold and some base metals. Distinctive alteration minerals have also been observed adhered to some of the pristine gold grains and this may be a useful exploration guide.

The new gold occurrence has been protected within the large block of hard rock or quartz claims recently staked by the Boulder / Western Prospector joint venture announced in a release dated September 14, 2004. This exciting new aspect to the Indian River Gold Project complements the gold found in conglomerate, and the outstanding potential of the original alluvial gold target.
