Capsule Geology

The Richfield showing is located 500 metres northwest of the west end of Fire Lake and 3 kilometres west-southwest of the peak of Fire Mountain.

A quartz vein cuts volcaniclastic sandstone and feldspathic greywacke ("greenstone") of the third member of the Lower Cretaceous Brokenback Hill Formation, Fire Lake Group. The vein, 0.15 to 0.36 metres wide on the surface, strikes 090 degrees for 33.5 metres and dips 26 degrees north. A 10.3 metre shaft shows that the vein pinches out at a depth of 4.6 metres.

Two channel samples, taken across an average width of 0.318 metres 3.0 metres down the shaft, assayed 0.69 grams per tonne gold (Minister of Mines Annual Report 1934, p. F16).

The vein was explored by Richfield Cariboo Gold Mines in the early 1930's.
