The Round Lake occurrence is located a few hundred metres north of Round Lake.

The showing is underlain by andesite or basalt of the Upper Triassic Karmutsen Formation, Vancouver Group. The rock is a massive dark green volcanic rock with occasional chlorite and epidote- filled amygdules. A small porphyritic diorite dike trending 308 degrees and a thin bed of limestone striking 125 degrees and dipping 60 degrees southwest, occur near the showing.

The Karmutsen volcanics are intensely altered to garnet-epidote skarn in an area of prominent shears and fractures. This zone has been injected by short veins and pockets of quartz that contain, or are adjacent to blebs, disseminations and stringers of pyrite, chalcopyrite and bornite. In 1987, one high grade sample assayed 3.21 per cent copper, 1.5 grams per tonne gold and 57.0 grams per tonne silver (Assessment Report 16101). A 3 metre chip sample contained 0.44 per cent copper and only moderately anomalous gold and silver (Assessment Report 16239).

In 1986, Corporation Falconbridge Copper geologists conducted a one day property examination on the claims. In 1987, Dellaterra Resources Ltd. optioned the claims and completed a program of geological mapping, geochemical analyses of stream sediments, soils and rock, and geophysical testing by magnetometer, VLF-EM and Induced Polarization. In 1989 and 1991, S.T.S. Resources explored the area. In 2012, a program of prospecting and rock sampling was completed on the area as the Old Joe property.
