At the main CB showing in an area 9 by 6 metres, chalcopyrite, pyrite, malachite and bornite? occur sporadically in narrow quartz-carbonate veins and veinlets, up to 15 centimetres wide, which are associated with shears intersecting a fault striking between 045 and 090 degrees. Hostrocks comprise Upper Triassic and? Lower Jurassic Nicola Group andesite lava with interbedded tuff and minor argillite. A rock sample assayed 0.51 per cent copper (Assessment Report 2403).

The original showings on the property were hand trenched probably early in the 1900s. Kamad Silver Co. Ltd. acquired the property and completed a prospecting program accompanied by four bulldozer trenches. In 1966, Nordco Explorations Limited carried out an induced polarization survey over 6 lines. From 1969 to 1970, geological, geochemical, ground magnetometer and an airborne geophysical (magnetometer and electromagnetic) survey were performed. In 1971, 2 holes were diamond drilled totalling 122 metres.
