Capsule Geology

The Cay occurrence is located on the north side of a peak, approximately 600 metres south of Melvin Lake.

The region is underlain by metasedimentary rocks of the Mississippian to Jurassic Bridge River (Complex) Group, intruded by dominantly granodioritic stocks of the Jurassic to Tertiary Coast Plutonic Complex. The showing is underlain mainly by metasedimentary rocks: argillite, chert and conglomerate with some andesite and serpentinite.

Locally, vuggy and limonitic quartz veins host pyrite, galena, malachite and possible tetrahedrite mineralization. In 1983, a 0.4-metre chip sample (CR-5) assayed 68.0 grams per tonne silver, while a 0.9-metre chip sample (CR-8) assayed 18.8 grams per tonne silver (Assessment Report 12281).

In 1980 and 1981, Denison Mines completed programs of geochemical sampling and geological mapping on the area as the Mel claims. In 1983, a program of geochemical sampling and geological mapping was completed on the area as the Cay property.
