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.

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).
