The HC Gold occurrence is located in the approximate centre of the HC claim group, about 6.5 kilometres south of the south shore of Taweel Lake, west of Clearwater. Wide bands of quartz-carbonate- mariposite alteration, enriched in gold, base metals and elements indicative of hydrothermal activity (Rebagliati, 1987), are hosted by fragmental basalt of the Triassic to Jurassic Nicola Group. Silver bearing quartz-calcite veins occur in the western part of the claim block, and are listed as a separate occurrence (HC Silver, 092P 189).
Three northwesterly trending zones of pervasive quartz-iron carbonate-mariposite alteration are located in the approximate centre of the HC claim group. The zones are discordant to bedding, display crude banding, brecciation, and crosscutting ferroan dolomite veining. They are interpreted by Rebagliati to be healed faults which have undergone multiple episodes of movement. Late quartz stringers infilling fractures, breccias and dilation zones within the broad areas of carbonate alteration carry the highest gold values, accompanied by minor concentrations of copper and antimony, and some silver.
Evidence of exploration of the silver mineralization on the west side of the HC claim consists of old shafts and pits. The first documented work on the ground was geological, geophysical and soil surveys done on the west side of the claim, over the silver anomaly (092P 189), by Imperial Oil Limited in 1972. In 1982, a regional reconnaissance program conducted by BP Selco identified altered rocks on the claim with anomalous values for mercury, arsenic and gold. BP Selco staked and prospected the ground, located the silver-lead-zinc mineralization, and continued prospecting to the east. This resulted in discovery of the gold-enriched alteration zones in the centre of the claim block. They conducted a 200 by 200 metre multi-element soil geochemical survey. In 1985, three alteration zones were trenched by backhoe. Lancer Resources optioned the HC claim from BP, and conducted a detailed soil geochemical survey. The B.C. Geological Survey conducted a regional till geochemistry program over NTS mapsheets 092P09W and 08W (Open File 2000-17).
