The Cap occurrence is located near Toozaza Creek in the Cassiar Mountains in northwestern British Columbia, about 142 kilometres north of the community of Dease Lake.
The showing area is underlain by metavolcanics, metasediments and serpentinites of the Mississippian-Permian Slide Mountain Complex. Joints, fractures and veinlets trend northeast, perpendicular to the fold axis in underlying sediments. Quartz veins and stockworks are associated with zones of silicified greenstone trending northeast. Disseminated pyrite (up to 5 per cent), pyrrhotite and manganese oxide occur in the quartz veinlets and the sulphides are associated with anomalous gold and arsenic values. The best assay from a chip sample over one metre assayed 0.754 gram per tonne gold (Assessment Report 11494). Listwanite zones with quartz veinlets up to 5 centimetres wide also occur in serpentinites on the property.
In 1982, the original Cap 1 to 5 claims were staked over strong barium and moderate zinc geochemical anomalies. In 1983, an exploration program was conducted by Spirit Petroleum Corporation and comprised grid preparation (89 kilometres), 1833 soil, 18 stream sediment and 179 rock samples collected, geological mapping, and trenching (four trenches were blasted and hand dug).
