The Cliff 6 showing area is underlain by Upper Triassic Stuhini Group rocks, which have been intruded by Late Triassic to Early Jurassic monzonitic intrusions, Eocene granitic dikes, sills and stocks and Miocene basaltic and rhyolitic dikes.

Mineralized rusty black shales with pyrite, chalcopyrite, galena and sphalerite and quartz veins were found. One sample of mixed limestone and shale with small veinlets assayed 3.5 grams per tonne silver, 0.22 per cent zinc and 0.035 per cent lead (Sample 1961, Assessment Report 19205). The following year sample 42222, taken in the same area, assayed 0.78 gram per tonne gold, 0.60 per cent zinc and 0.033 per cent copper. This sample was collected from a 1 metre pod of quartz veinlets in a pyritic shale.

The Cliff 1 to 9 claims were staked in July, 1988. Prospecting and sampling programs were carried out by Corona Corporation in 1988 with follow-up work in 1989. In 1990, a total of 21 rock, 11 heavy mineral, 81 soil and 5 silt samples were collected by Braiden Resources during the nine day sampling program on the Cliff 1 to 9 claims.
