Abstract

The Buttle Lake mining camp (49°34ʹ north, 125°36ʹ west) is located in Strathcona Park near the south end of Buttle Lake, 90 kilometres southwest of Campbell River, British Columbia (Figure 25). It is a major volcanogenic massive sulphide district hosted by the Myra formation of the Paleozoic Sicker Group. Past production has come from several mines: Lynx open pit, Lynx underground mine, Myra open pit and H-W underground mine. The Price deposit, discovered early in the history of the camp, has received sporadic work but has not been mined. Current production is from H-W mine, however, ore from the recently discovered Battle and Gap zones will be mined in late 1993. Between 1966 and 1992, 13.8 million tonnes of ore grading 1.9% copper, 5.6% zinc, 0.6% lead, 2.2 grams per tonne gold and 64.0 grams per tonne silver had been mined from the camp (Westmin Annual Report, 1992). Of this, 7.5 million tonnes are from H-W, 5.3 million tonnes are from Lynx and 1.0 million tonnes are from Myra mine. Geological reserves as of 1992 are in Table 1 and total more than 12 million tonnes. Exploration within the camp has also defined several new prospective zones. These are: Trumpeter, Ridge and the Main Zone Extension (Figure 25).
