Capsule Geology

The Chilco showing is located 32.5 kilometres northwest of the north end of Harrison Lake. Precious metal bearing sands cover a 400 to 800 metre wide section of the Lillooet River valley, to depths in excess of 40 metres.

The post-Pleistocene alluvial sands contain gold, silver, platinum and palladium in submicron sized particles. A 1.4 kilogram sample of sand, taken at least a metre below surface, assayed 2.47 grams per tonne gold, 4.80 grams per tonne silver, 2.77 grams per tonne platinum and 2.71 grams per tonne palladium (Assessment Report 2589, p. A2, Sample H-59).
