The Stan showing is situated north of Brandywine Creek on the southern slopes of Metal Dome, approximately 16 kilometres west of Whistler, British Columbia.
The Brandywine Creek region is underlain by Lower Cretaceous Gambier Group volcanic and sedimentary rocks which are preserved as a roof pendant, the Callaghan Creek roof pendant, within dioritic to granodioritic rocks of the Jurassic to Cretaceous Coast Plutonic Complex. The Stan property lies west of the Callaghan Creek roof pendant and is underlain primarily by a dioritic complex. However, andesitic greenstone outcrops on the property and is presumed to be Gambier Group. Pliocene Garibaldi Group basalt and rhyodacite flows and pyroclastic rocks crop out in the southwest.
Mineralization consists of pyrite, chalcopyrite, bornite, sphalerite, pyrrhotite and malachite as disseminations, massive sulphide bands and possibly skarn, all apparently hosted by sheared greenstone.
The best assay from 1988 was a 50-centimetre chip sample (Sample 18361) of fine-grained greenstone with stringy chalcopyrite, pyrite and bornite which graded 0.098 gram per tonne gold, 0.45 per cent copper and 9.2 grams per tonne silver (Assessment Report 18788). In 1989, grab sample KRS-15, from chlorite schist containing massive and disseminated pyrite, assayed 9.15 grams per tonne gold, 19.7 grams per tonne silver and 0.14 per cent copper (Assessment Report 20174).
Between 1991 and 1995, a number of soil geochemical sampling programs were carried out. In 1994, soil geochemistry samples yielded 0.41 gram per tonne gold, 0.12 per cent copper, 0.05 per cent lead, 0.02 per cent zinc and 5.6 grams per tonne silver (Assessment Report 23639). Anomalous gold values are associated with anomalous copper values. In 1995, similar results were obtained (Assessment Report 24218).
