The Kunlin Lake occurrence is reported to occur north, and a little west, of Kunlin Lake on the north side of a valley.

The area is underlain by Upper Triassic Vancouver Group rocks consisting of Karmutsen Formation basalts overlain by Quatsino Formation limestone. These are intruded by the Jurassic Island Intrusions consisting dominantly of quartz diorite with lesser diorite and granodiorite.

Locally, a zone impregnated with chalcopyrite, pyrite, pyrrhotite and chalcocite and another with quartz carrying a large quantity of arsenopyrite are reported. In 1973, a sample assayed 1.37 grams per tonne gold, 9.26 grams per tonne silver and 0.39 per cent copper. Other samples yielded up to 0.50 per cent copper (Assessment Report 4972).

During 1973 through 1977, W. Babkirk prospected the area as the Donner and Heber claims. A lone drill hole, totalling 60 metres, was completed in 1976 on the area north east of Kunlin Lake. The hole intersected a breccia zone hosting quartz veins and chalcopyrite near the end of the hole. Another hole, totalling 61.3 metres, was completed the following year but only intercepted trace sulphides. No assays were reported for either drill holes.
