Capsule Geology

The property is located 3 kilometres north of Cumshewa.

The area is underlain by Middle Jurassic Yakoun Group rocks consisting of porphyritic andesite agglomerate, tuffs and volcanic sediments that are cut by mafic and felsic dikes. The strata dip gently to the north.

Disseminations and stringers of pyrite, arsenopyrite and stibnite occur in carbonate altered rhyolite, rhyolite porphyry, breccia, and andesite. Drilling encountered higher gold values associated with quartz-calcite-pyrite-arsenopyrite veinlets in an area 600 by 600 metres in size. A 6 metre intersection in drill hole B75-1 assayed 1.5 grams per tonne gold (Assessment Report 5431). A 1988 drill hole encountered 3 grams per tonne gold over 3.05 metres (Assessment Report 17390, page 5). Surface samples have assayed up to 5 grams per tonne gold over 1 metre (Assessment Report 17390, page 5).

This showing was discovered by Efrem Specogna in 1972. The property was optioned by Umex Corp. and Chevron Minerals in 1974 and 1975. Work by these companies included soil and rock sampling and geological mapping, and the drilling of five holes totaling 350 metres. Thunderwood Explorations completed an airborn magnetometer surveys in 1980. The showing was restaked by Cominco Ltd. in 1986. By the end of 1987 the company had completed line cutting, an induced polarization survey (28 kilometres), soil sampling and geological mapping over the showing and surrounding area. Cominco drilled 33 percussion holes totaling 2500 metres in 1988 to test induced polarization anomalies over the showing. Cominco continued work in 1995 with the flying of an airborn electromagnetic and magnetometer survey over the region totaling 228 kilometres.
