The Cave 1 occurrence is located east of the southern arm of Horne Lake, approximately 1.8 kilometres south- south east of the Silver Bell (MINFILE 092F 243) occurrence.

The Cowichan uplift consists mainly of northwest trending volcanic-volcaniclastic-sedimentary rocks of the Paleozoic Sicker and Buttle Lake groups. These are bounded by younger mafic volcanics of the Vancouver Group and sediments of the Nanaimo Group. The stratigraphy is very complex with numerous intercalations and rapid lateral facies changes. The rocks are commonly schistose in the vicinity of faults with associated carbonatization and silicification.

Locally, sericite-quartz-carbonate altered volcanics of the Devonian Nitinat Formation, Sicker Group contain finely disseminated pyrite, chalcopyrite and stibnite. A major northwest trending fault occurs to the east of the showings.

In 1982, Asarco Exploration Co. of Canada, Limited completed a program of soil geochemical sampling on the area as the SB claim. From 1986 through 1988, Nexus Resources and Reward Resources completed programs of prospecting, geological mapping and rock and silt geochemical sampling. One sample (JW8815R) containing about 5 per cent pyrite, 2 per cent chalcopyrite and traces of stibnite and arsenopyrite assayed 0.32 per cent copper (Assessment Report 17730). One of the copper bearing samples was described as a schist. In 1991, A.B.L. Whittles prospected the area as the Silverbells claim.
