The Custer Ridge occurrence is located north side of Depot Creek, south of Mount Edgar, at an elevation of 1746 metres.

The area is underlain by the Custer Gneiss, a package of rocks derived from Mesozoic and possibly Paleozoic rocks and metamorphosed in the Late Cretaceous and early Tertiary. The granodioritic Oligocene Chilliwack Batholith intrudes the country rock.

Locally, a 40 centimetre wide quartz vein, trending 330 degrees, hosts galena, pyrite, chalcopyrite and minor sphalerite mineralization.

In 2010, three samples (JLR011 to JLR013) of porphyry boulders hosting 5-centimetre wide quartz veins assayed from 0.06 to 0.23 per cent copper, 0.04 to 0.36 per cent lead, 0.01 to 3.97 per cent zinc and 12 to 53 grams per tonne silver (McDonough, B. (2011-04-02): Technical Report on the Cu-Au-Mo Properties).

In 2011, a rock sample (K881076) assayed 0.085 gram per tonne gold, 23.3 grams per tonne silver, 0.420 per cent lead, 0.967 per cent zinc and 0.021 per cent molybdenum (Assessment Report 32420).

Work History

During 2010 through 2012, Miocene Metals completed programs of rock and silt sampling, and 1296.6 line-kilometres of airborne geophysical surveys on the area as part of the Southern Properties project.
