The Cliff 1 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.

A shear zone located in the southeast corner of the Cliff 1 claim. Nine samples were collected from the 20 to 40 centimetre wide quartz vein in the center of the shear, as well as the surrounding zone and the altered quartzite. Of these nine, 5 samples showed anomalous values in silver and base metals. Gold was only slightly anomalous in two of the nine samples. A 40 centimetre sample across a quartz vein containing chalcopyrite, pyrite and trace galena and sphalerite assayed 0.26 gram per tonne gold, 106.8 grams per tonne silver, 0.13 per cent copper, 0.07 zinc (Assessment Report 20346).

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.
