The BR showing is located northwest of Salal Creek at the headwaters of Bridge River.
The area is underlain mainly by intrusive rocks of the Lord Pluton, an Early Tertiary intrusive complex of the Coast Plutonic Complex. Locally, Pleistocene volcanic rocks of the Garibaldi Group overlie the pluton. The dominant rock types include quartz monzonite, biotite granodiorite and quartz diorite with minor amounts of gabbro, hornblendite and intrusive breccia. Dikes of aplite, andesite, feldspar porphyry and gabbro also cut older intrusive rocks.
Sulphide mineralization, mainly chalcopyrite and molybdenite, is strongly fracture controlled, confined to veins and veinlets mainly within quartz monzonite over an area of 1700 by 500 metres. Veins commonly strike north and dip 50 to 70 degrees east. Other sulphide minerals present include bornite, chalcocite and pyrite; oxidation products of sulphides include malachite, azurite and tenorite. Wallrock alteration is weakly propylitic, with sericite and potassium feldspar associated with quartz and sulphides in, and adjacent to, veins.
In 1980, a chip sample (61901) across a 1.0 metre wide mineralized quartz vein from the East Gully assayed 1.08 per cent copper, 0.050 per cent molybdenum and 15.7 grams per tonne silver. Trench sampling (trenches 2W and 2E), from the West Gully, yielded up to 0.14 and 0.19 per cent copper over 17 and 6 metres, respectively (Assessment Report 8804).
In 2012, diamond drill hole CP11-01 intercepted 99.1 metres averaging 0.051 per cent copper, including 12.2 metres yielding 0.149 per cent copper (Assessment Report 33319).
In 1970, Canex Aerial Exploration completed programs of geological mapping and an induced polarization survey, totalling 2.5 line-kilometres, on the area as the BR claims. In 1980, Amax of Canada completed a program of geological mapping, ground geophysical surveys and rock, silt and soil sampling. During 2005 through 2012, programs of prospecting, geochemical sampling, trenching, an induced polarization survey and 2031.5 metres of diamond drilling in nine holes were completed on the area as the Copper 1-25 claims.
