Walker Creek Prospect

The Walker Creek prospect lies in the south-eastern section of the WUSA Gold Project. The prospect was explored, including drilling, by the surface/mineral rights landholder in the late 1980’s to early 1990’s. It consists of a large altered zone within layered basaltic/rhyolitic volcanic rocks interpreted to be associated with an Oligocene-Miocene age (Little Butte Volcanic Series) vent. A maar type hydrothermal vent controlled adularia alteration and associated epithermal gold mineralization that pervaded clastic and pyroclastic sequences developed proximal to the vent.

Surface sampling, mapping and drilling (10 holes) defined highly anomalous gold, with co-extensive silver, mercury and antimony within the altered area. Eight holes intersected gold mineralization with a peak of 12.2m @ 1.41 g/t Au in WC-290 including 1.52m @ 4.9 g/t Au. Holes WC-190, WC-290, WC-390 and WC-890 were drilled in altered and mineralized zones and returned anomalous gold. Drill holes 590, 690, 790 were collared in basalt and targeted to intersect altered vent facies pyroclastics beneath the basalt.

The true thickness of mineralized intercepts is not known, however mineralization was interpreted to be flat dipping suggesting true thickness should be greater than 80% of drilled thickness.

The main rock type that hosts gold is a bedded vent facies pyroclastic, with chaotic pyroclastic breccia also considered suitable hosts. A potential vent feature was defined by sparse drilling.

Alteration included quartz, clay, adularia and pyrite, resulting in a low-sulphidation classification for the prospect. Explorers of the day considered Walker Creek to be a “significant new gold occurrence of the Western Cascade Mountains”.

Explorers of the time noted Walker Creek to be a “significant new gold occurrence in the Western Cascade Mountains” however no further drilling was completed.
