The Sicker 1 occurrence is located on the north eastern slope of Mount Sicker, approximately 12 kilometres north-northwest of Duncan.
The area is located within the Cowichan uplift and is underlain mainly by andesitic to rhyolitic volcanics of the McLaughlin Ridge and Myra Formations, (Sicker Group). The local stratigraphy is disrupted by folding, faulting (pre-Triassic as well as Tertiary), intrusions of gabbro and diabase sills and dikes (informally known as the Mount Hall gabbro) that are coeval with the Upper Triassic Karmutsen Formation, (Vancouver Group).
Locally, strongly chlorite altered quartz-feldspar phyric rhyolite contains abundant chalcopyrite stringer mineralization. Immediately to the east, the altered rhyolite contains pods of massive magnetite up to 1 metre thick. These magnetite pods are flanked by zones of intense chlorite alteration and are cored by medium to coarse grained semi-massive pyrite.
In 1982, a three hole drill program, totaling 107 metres, was completed. Drill core samples yielded values up to 0.34 gram per tonne gold, 8.6 grams per tonne silver and 0.1 per cent lead (Assessment Report 11841). The exact location of the drill holes is unknown.
In 1985 and 1986, Falconbridge Copper completed programs of geological mapping, rock sampling and an induced polarization survey on the Sicker and Rocky claims. Sample 2373 assayed 8.2 grams per tonne silver, with minor copper and zinc values (Assessment Report 13907).
In 1988 and 1989, Minnova completed programs of geochemical sampling. In 2008, Westridge Resources completed a program of airborne geophysical surveys on the area. In 2010, grab sampling yielded values up to 1.59 per cent copper and 9.6 grams per tonne silver (Assessment Report 31677).
