DESCRIPTION OF
DEPOSIT
The deposit is situated within Precambrian Amisk Group volcanic and
related intrusive rocks of the Flin Flon-Snow Lake greenstone belt. Geologically
it is similar to the Ghost Lake and Chisel Lake deposits (See: Mind No. 829 and
No. 828).
The footwall of the deposit consists of a 100-250 m thick unit of
interlayered massive dacite tuff and lapilli-tuff. A 0.5-10 m thick unit of
felsic breccia overlies the massive sulphides (Fedikow et al, 1989). The deposit
appears to occur in a silcic volcaniclastics near the contact with mafic
volcaniclastics (Gale et al, 1980).

HISTORY OF
EXPLORATION AND DEVELOPMENT
The deposit is located near Potten Lake, 0.4 km southwest of the Ghost
Lake mine and 0.8 km southeast of the Chisel Lake mine (See: Mind No.
828).
The property had been staked as Ox No.25 by Charles Asmes and assigned
to Hudson Bay Exploration and Development Company Ltd. (HBED) in 1955. The
property was assigned to and leased as M-7181 for 21 years by Hudson Bay Mining
and Smelting Co. Ltd. (HBM&S) in 1960.
The deposit was outlined as two
small lenses during diamond drilling “to test a structural interpretation of the
Lost Lake area, near the Ghost Lake mine” HBM&S in 1974 (HBM&S
Annual Report, 1974)The mineralization contained in the two lenses compromised
224 300 tonnes (t). One lens, containing 84 000 t with a grade of 2.91 g/t
(0.085 oz/ton) Au, 81.3 g/t (2.37 oz/ton) Ag, 1.45% Cu and 4.9% Zn, and 1.0% Pb
was to be mined from the Ghost Lake decline.
In 1977, a drive was started
from the 200 m (650 ft.) level at Chisel Lake toward Ghost Lake, and a decline
from Ghost Lake toward the Lost Lake zone (HBM&S Annual Report,
1977). The haulage connecting Chisel Lake to Ghost Lake was completed in 1978,
and development of the Lost Lake ore zones continued, and production was
scheduled for 1979 (HBM&S Annual Report, 1978). Production, however, was not
reported in 1979 (HBM&S Annual Report, 1979).
On June 28, 1979, the new
crusher and concentrator at HBM&S’ Stall Lake mine (See: Mind No. 480)
officially opened. Developmental ore from Lost Lake was transported
underground to the Chisel Lake mine and then trucked to the Snow Lake mill where
a “(Chisel) circuit completes some 1000 tons (907 t) per day of combined
Chisel-Ghost Lake ore at an average grade of 9.5% Zn, 0.5% Cu and 0.7% Pb”
(Northern Miner, June 28, 1979).
As of January 1, 1981, combined proven
reserve of Ghost Lake and Lost Lake orebodies were 332 000 t grading
1.08% Cu, 0.3% Pb, 6.5% Zn, 32.5 g/t (0.95 oz/ton) Ag, and 1.2 g/t (0.035
oz/ton) Au.
The lease was renewed in 1981, and production continued with the
Ghost Lake mine. It is assumed that the Lost Lake production ceased in
1988 when Ghost Lake closed.
