Capsule Geology

The Musketeer occurrence is located in Strathcona Park, along the Bedwell River. The area is underlain by quartz diorite of the Bedwell River batholith which is part of the Early to Middle Jurassic Island Plutonic Suite. Locally, fine-grained quartz diorite may represent a later phase of the intrusive. Andesite dykes, some of which are strongly altered, cut the intrusive rocks. Andesitic flows of the Upper Triassic Vancouver Group, Karmutsen Formation, lie 1.5 kilometres to the west.

Five veins are recognized within a 260 metre area. The veins follow shears that occupy two orientation sets. One set strikes 010 to 030 degrees and dips 85 degrees west to 75 degrees east and the second set strikes 045 to 090 degrees with dips ranging from 45 to 75 degrees north.

The Musketeer vein, hosted in the second set of shears, strikes 80 degrees, dips 50 degrees north and is 225 metres long. It cuts and slightly off-sets the Trail vein, the Rob vein, the Musketeer #1 vein and the Bonus vein, which all belong to the first set of shears.

The veins consist mainly of well-crystallized quartz and white carbonate, with varying amounts of fine free gold, pyrite, sphalerite, galena and chalcopyrite. Pyrite and sphalerite are locally coarse. Vein widths range from less than 1.0 centimetre to 30.0 centimetres, with wider sections occurring at splays in the veins. The sulphides occur as ribbons where the veins are banded, or as irregular masses elsewhere.

Assays from the 700 level of the Trail vein range up to 166.65 grams per tonne gold and 106.30 grams per tonne silver over 25.4 centimetres (sample No.25, Bulletin 13, page 45). A sample over a strike length of 51.5 metres on the 850 level averaged 39.43 grams per tonne gold over 25.4 centimetres (Bedwell River Gold Mines, 1959). Samples from the Musketeer vein assayed between 4.8 grams per tonne gold over 17.8 centimetres and 169.7 grams per tonne gold over 11.4 centimetres (Bulletin 13, page 40).

In 1942, reserves of 18,034 tonnes, grading 11.32 grams per tonne gold were reported (Northern Miner, November 28, 1974). Production from the Trail and Musketeer veins in 1942, 1961, 1962, 1963, 1974 and 1975 totalled 9,623 tonnes of 9.87 grams per tonne gold, 5.61 grams per tonne silver, 1.15 per cent lead and 0.005 per cent copper.
