The occurrence is located just northeast of the toe of Berendon Glacier. The area is underlain by strata of the Lower Jurassic Unuk River Formation, Hazelton Group. These strata consist of argilla- ceous sediments, outcropping at lower elevations, overlain by dacitic tuffs and andesitic fragmentals. A north trending extension of Lower Jurassic Summit Lake stock hornblende granodiorite intrudes the country rock. This intrusive lobe is from 300 to 500 metres wide and separates the dacitic tuffs on its east from the andesitic fragmentals on its west.
Mineralization was encountered in drill hole TV 86-1, which was drilled on an electromagnetic anomaly and a zone of arsenopyrite filled fractures in granodiorite. This north trending hole cut granodiorite for the first 105 metres and tuffaceous rocks for the last 100 metres.
Quartz veins up to 15 centimetres wide cut the granodiorite and contain up to 8 per cent pyrite and 1 per cent arsenopyrite. A few minor quartz veins contain up to 70 per cent arsenopyrite and 10 per cent pyrite. Silicified sections of the granodiorite contain up to 10 per cent pyrite, 2 per cent arsenopyrite and minor chalcopyrite.
A weighted average of two assays from adjacent drill sections gave 3.18 grams per tonne gold and 13.03 grams per tonne silver over a combined length of 1.37 metres. This drill interval consisted of silicified granodiorite with arsenopyrite and chalcopyrite (Assessment Report 15626).
