DESCRIPTION OF DEPOSIT
The Ghost Lake area is underlain by Precambrian Amisk Group volcanic and related intrusive rocks of the Flin Flon-Snow Lake greenstone belt. The rocks in the mine area have been mapped as basic pyroclastic rocks, amphibolites and quartz-feldspathic rocks. The orebody is reported to occur in quartz-biotite- (garnet) gneiss at the contact with the andesite hangingwall. Reference is made to chlorite-biotite schist, hornblende schist, and carbonate in the drill logs. Sericite is plentiful in the mineralized zone. The hangingwall rocks are reported to be typical of the Amisk pyroclastic rocks and older shallow intrusives (amphibolite). Footwall rocks are said to also contain staurolite, which suggests that metasedimentary rocks are intercalated with the Amisk volcanic rocks.
The ore in the deposit occurs in irregular, solid sulphide lenses in an orebody that strikes northwest and dips toward the northeast. The ore consists mainly of sphalerite, along with some chalcopyrite, pyrrhotite, pyrite and galena.
ASSOCIATED MINERALS OR PRODUCTS OF VALUE
Copper (Cu), silver (Ag), lead (Pb) and gold (Au).
HISTORY OF EXPLORATION AND DEVELOPMENT
This deposit, discovered in 1956, is located 244 m (800 ft.) southeast of Ghost Lake, about 1.2 km (0.75 mi.) east of the Chisel Lake mine (See: Mind No. 828). In 1956, 6465 m (21 207 ft.) of diamond drilling indicated an orebody containing 236 500 tonne (t) (260 700 tons) averaging 11.6% Zn, 1.42% Cu, 39.08 g/t (1.14 oz/ton) Ag, 0.45 g/t (0.013 oz/ton) Au and 0.91% Pb. The lenticular orebody was outlined by drilling to dimensions of 90 m (300 ft.) long, 90 m (300 ft.) wide and up to 14 m (40 ft.) in width.
In 1965, an access road was completed, and in 1966, exploration drilling totalled 825 m (2702 ft.). Development of the property started in 1970, by driving a decline 5 m (17 ft.) wide and 3 m (10 ft.) high at a minus 20 grade. In 1971, the decline reached the ore zone at the 170 m (560 ft.) level; and stope development was started. Levels were later established at 111, 145 and 170 m (365, 475 and 560 ft.) below surface.
In 1972, reserves were estimated at 263 000 t (290 000 tons) grading 14.5% Zn, 1.58% Cu, 7.61 g/t (0.022 oz/ton) Au, 35.3 g/t (1.03 oz/ton) Ag and 0.3% Pb. The mine, which was officially brought into production on August 21, 1972, was mined at the rate of 250 tons per day. Ore was transported 1.6 km (98 mi.) by train to be processed into electrolytic zinc and blister copper at Flin Flon.
As of January 1974, reserves were 135 100 t (149 000 tons) grading 14.2% Zn, 1.80% Cu, 0.3% Pb, 38.4 g/t (1.12 oz/ton) Ag and 0.82 g/t (0.024 oz/ton) Au (Cranstone and Hamilton, 1976).
In 1975 production was reduced as a result of mining remnants. Further reduction occurred in 1976, to prevent excess build-up of refined zinc inventory at the Flin Flon Plant.
Production was curtailed in 1978, as the Lost Lake ore zone (See: Mind No. 869) was being developed from the Ghost Lake decline. The 200 m (650 ft.) level haulage connecting Ghost Lake to Chisel Lake’s production shaft was completed in 1978.
Production continued until 1988 when the mine closed (Canadian Mines Handbook, 1990).
