The Buccaneer occurrence is located in Strathcona Park on the Bedwell River. The area is underlain by quartz diorite of the Bed- well River batholith which is part of the Early to Middle Jurassic Island Plutonic Suite. Andesitic flows of the Upper Triassic Vancouver Group, Karmutsen Formation lie 2.4 kilometres to the west.

The occurrence comprises the West vein and the Craig vein which are 200 metres apart and follow altered andesite dykes for much of their length. The veins and dykes follow branching fractures that strike approximately 025 degrees and dip steeply east. The dykes range in width from 0.05 metres to 7.6 metres, averaging 2.4 metres. The veins may be within the dykes or they may follow either side of the contact of the dyke and quartz diorite.

The veins are 0.05 to 0.51 metres wide, locally anastomosing to 1.2 metres. Vein material consists of well crystallized quartz, calcite, minor chlorite, and wallrock fragments that are sometimes altered to ankerite. Sulphide content is usually less than 1.0 per cent and includes scattered grains of chalcopyrite, pyrite, galena, and sphalerite. Locally, malachite, covellite, chalcocite, limonite and anglesite are present as alteration prod- ucts. Fine-grained free gold is irregularly distributed in the gangue or with the sulphides.

The Craig vein has been traced underground for over 250 metres at two levels and is up to 0.51 centimetres wide, averaging about 0.14 metres. Assays range up to 316.15 grams per tonne gold and 75.44 grams per tonne silver (sample number 32, Bulletin 13, page 57).

The West vein has been traced on surface for 275 metres, and underground for about 145 metres. Common vein widths are about 0.19 metres. Samples assayed from trace to 538.35 grams per tonne gold and 99.44 grams per tonne silver (sample number 1, Bulletin 13, page 59).

Results of 1939 surface sampling along a strike length of 134.1 metres indicates a weighted average value of 19.55 grams per tonne gold over 0.91 metres (Buccaneer Mines Limited, 1939 Assay Plan). It is not clear whether this information is from the Craig or the West vein.

Production in 1941, 1942, 1947, 1958 and 1959 totalled 4987 tonnes containing 121,581 grams of gold, 39,128 grams of silver, 3206 kilograms of lead and 315 kilograms of copper.
