This is a minor copper showing, situated on the east shore of Dall Lake, 5 kilometres from its southern end, 23 kilometres west-southwest of Mount Winston in the Cassiar Mountains (Geological Survey of Canada Map 42-1962).

The occurrence lies in an infolded area or belt of Cambrian limestone, which overlies Upper Proterozoic and Lower Cambrian siliciclastic and carbonate rocks (Geological Survey of Canada Maps 42-1962, 1712A, 1713A). The region is southwest of the Northern Rocky Mountain Trench, and is part of the Cassiar terrane. A few kilometres to the west, the rocks are cut off by the right-lateral Kechika Fault.

The only known records of the mineralization describe minor chalcopyrite in numerous veinlets cutting intensely silicified limestone (Bulletin 12, page 52; Geological Survey of Canada Map 42-1962, marginal notes).
