DESCRIPTION OF DEPOSIT
Sulphides occur along the crests of folds in the grey, Precambrian, banded gneisses of the Amisk group, on the eastern extension of a syncline. The tabular deposit strikes east, dips 45N, and plunges north. No. 1 orebody is 76 m (250 ft) long, averages 4.6 m (15 ft) wide, and is 686 m (2250 ft) thick. No. 4 orebody is centered 152 m (500 ft) west, along strike from No. 1. No. 4 is 84 m (275 ft) long and its average width is 6 m (20 ft). It extends from 503 to 869 m (1650 to 2850 ft) below surface, but is open at depth. Two other ore zones form sheets between No. 1 and No. 4. There are also several disseminated orebodies between surface and 549 m (1800 ft).
Pyrrhotite, pyrite, chalcopyrite, and minor sphalerite occur as coarse, recrystallized masses and as disseminations. Hexagonal pyrrhotite with chalcopyrite and sphalerite occurs in the upper part of the mine. Monoclinic pyrrhotite with pyrite, chalcopyrite, and sphalerite is found in the lower part of the mine. Gold and silver were found by assays and ore processing.

HISTORY OF EXPLORATION AND DEVELOPMENT
The mine is located west of Wekusko Lake, at the western end of Stall (Miller) Lake, on the C.N. railway to Osborne Lake. Provincial Road 393 goes past the mine.
Col 5 (P 9277) was staked by Colin Baker in 1945. No work was done and it was cancelled two years later.
Astra 18 (P 35444) was staked in 1955, by W.F. Uhrich. Shortly afterward, it was assigned to Walter Johnson. In September of that year, Hudson Bay Exploration and Development Company Limited (H.B.E.D.) optioned the property. Geophysical surveys were probably made about this time.
In 1956, H.B.E.D. did over 17 374 m (57 000 ft) of diamond drilling in this area, including 4026 m (13 210 ft) on Astra 18. The company took up their option, and the claim was assigned to H.B.E.D. The site was cleared, and ore reserves were estimated to be 710 700 tonnes (t)(783 200 tons) averaging 0.69 grams/tonne (g/t) (0.020 oz/ton) Au, 9.26 g/t (0.27 oz/ton) Ag, 4.54% Cu, and 0.4% Zn (Hudson Bay Mining and Smelting Co. Limited (H.B.M.&S.), 1956 Annual Report).
An airborne electromagnetic survey was done by Canadian Nickel Company Limited, under Airborne Permit No. 19, in 1957 (Non-confidential Assessment File No. 91624, GroundHog Sheet No. 10).
The power line from Snow Lake and the road from Provincial Road 392 were completed in 1957. The 3-compartment production shaft was started and sunk 217 m (713 ft). The shaft was deepened in 1958, to 483 m (1585 ft) and in 1959, to 632 m (2073 ft). Stations were established at approximately 46-m (150-ft) intervals between 274 and 594 m (900 and 1950 ft). During 1958-59 exploration diamond drilling totalled 2676 m (8780 ft) (H.B.M.&S., 1957-59 Annual Reports). The claim was transferred to Hudson Bay Mining and Smelting Co. Limited (H.B.M.&S.), in 1959, and leased as M-5716.
Underground drilling, in 1960, proved ore to be at least 762 m (2500 ft) below surface, but mineralization below the 594 m (1950 ft) level was not calculated in reserves. The shaft was continued to 811 m (2660 ft) with stations cut at 640 m, 686 m, 732 m, and 777 m (2100 ft, 2250 ft, 2400 ft and 2550 ft). In 1961, exploration diamond drilling totalled 2735 m (8974 ft). Underground exploration and development included 2713 m (8902 ft) of lateral work. Surface lease M-103 was issued. In 1962, the reserve estimate was increased to 1 351 000 t (1 489 000 tons) grading 5.4% Cu (Northern Miner, May 3, 1962) and then to 1.4 million t (1.5 million tons) grading 5.50 to 6% Cu (Northern Miner, November 22, 1962). The production shaft was completed to 896 m (2941 ft). Levels were established at 823 m and 869 m (2700 and 2850 ft). A 3-compartment service shaft was collared and sunk 14 m (47 ft).
The service shaft reached its final depth of 872 m (2862 ft) in 1963. The mine produced 1477 t (1628 tons) of ore, which was sent to Ottawa for testing. Development continued and almost 3048 m (10 000 ft) of exploration drilling was done.
The mine came into production on the first of February ,1964 (See History of Production for production figures). Diamond drilling and development work continued through 1967. In 1967, the amount of exploration drilling increased sharply. The following year, two holes, drilled in conjunction with Falconbridge Nickel Mines Limited, cut ore 457 m (1500 ft) below surface along the eastern boundary of the Hudson Bay property. Development took place on the 823 m and 869 m (2700 and 2850 ft) levels of the mine. Mining was done by the horizontal cut and fill method.
Proven reserves as of January 1, 1968, were 1 899 800 t (2 093 600 tons) grading 1.51 g/t (0.044 oz/ton) Au, 10.63 g/t (0.31 oz/ton) Ag, 5.21% Cu, and 0.5% Zn (World Mining, February 1969). In 1969, H.B.M. & S. reported that development work and exploration diamond drilling found an additional 672 400 t (741 000 tons) of ore, averaging 3.5% Cu (H.B.M.&S. Annual Report, 1969). Production was halted in November 1970, so that a winze could be sunk from the 869 m (2850 ft) level. The 3-compartment winze was completed to 1097 m (3600 ft) two years later. Drifting on the 594 m (1950 ft) level began in 1970, in an attempt to intersect the ore found on the eastern border of the property in 1967. The 1829 m (6000 ft) drift was completed in 1972, and was successful in locating the small orebody (H.B.M.& S. Annual Report, 1970). After full production resumed, by 1973 most of the No. 1 orebody was mined out (Northern Miner, July 26, 1973).
As of January 1974, reserves at the Stall Lake Mine were 3 086 660 t (3 401 500 tons) grading 4.85% Cu, 0.6% Zn, 8.57 g/t (0.25 oz/ton) Ag and 1.13 g/t (0.033 oz/ton) Au (Cranstone and Hamilton, 1976). During 1974, a total of 576 m (1889 ft) of underground drilling was done on Astra 18, and this, together with underground development work, added 334 800 t (368 900 tons) of reserves below 869 m (H.B.M.&S. Annual Report, 1974). By 1975, ore was developed to 1097 m (3600 ft) with more ore at this level, than at any higher level (Financial Post, August 23, 1975).
In 1977, ore production increased gradually, and was maintained at 20 000 t (22 000 tons) per month towards the end of the year. Diamond drilling below the 914 m (3000 ft) level indicated additional ore to the 1402 m (4600 ft) level (H.B.M.&S., Annual Report 1977). This is a continuation of the No. 4 orebody (H.B.M.&S., Annual Report 1978).
A shortage of skilled miners and tradesmen affected production at Stall Lake during 1980 (H.B.M.&S., Annual Report 1980).
The main 3-compartment production shaft (original depth 896 m (2941 ft), levels at 46 m (150 ft) intervals) was deepened in 1978. The 4th shaft collared on the 869 m level was to be sunk to 597 m (1960 ft) to reach the orebody on the 1097 m (3600 ft) level (White, 1981). Work was completed on the No. 4 internal shaft in 1979. The No. 4 orebody was confirmed to the 1402 m (4600 ft) level.
Work done by the Manitoba Government included: sample collection for an industrial minerals study by Yamada (1984); outcrop sampling for trace element analyses by Eccles and Fedikow (1985); and experimental Aurex-cup mercury gas surveys (Eccles and Fedikow, 1985; Fedikow, 1986). The following measured and indicated reserves were reported:

As of December 31, 1984, ore reserves were reported at 2 105 683 t grading 4.42% Cu, 0.3% Zn, 1.2 g/t Au, 5.1 g/t Ag, and 0.016% (estimated) Pb (Lemieux and Laughlin, 1985). As of December 31, 1984, production and reserves totalled 6 264 000 t grading 4.33% Cu and 0.48% Zn (Bamburak, 1990, p. 6). Underground drilling was undertaken in 1989, to test the area between the Stall and Rod mines from the 590 m exploration drift (Northern Miner Magazine, March 1989).
In 1990, Hudson Bay began mining in conjunction with the nearby Chisel Lake mine (See: Mind No. 828). In 1992, Hudson Bay announced their intent to close the mine by 1994. The Stall Lake Mine was closed February 1994, due to depletion of resources (Canadian Mines Handbook, 1994-1995).

REMARKS
Minor chalcopyrite with pyrite and pyrrhotite was found on Fox 5 and 13, north of Snow Creek, when Guardian Mines Limited diamond drilled a Turam anomaly in 1967 (Non-confidential Assessment File No. 90139).
The shafts and most of the reported work were done on Astra 18 and hence its history described on this card. The orebody being mined by the 1829 m (6000 ft) drift is the No. 2 zone described on mineral inventory card 481(Rod mine).
Construction of a 3448 t (3800 ton) concentrator, adjacent to Stall Lake mine, began July 4, 1977, with first ore treated in April 1979, and in production by end of the year. The design provides for 2 separate treatment circuits: one for ore from Chisel and Ghost Lake mines (See: Mind Nos. 828 and 104#); the other for ore from Stall, Anderson and Osborne Lake mines (See: Mind Nos. 482 and 479). Copper and zinc concentrates were shipped to metallurgical plant at Flin Flon, along with a lead concentrate sold directly to a lead smelter. Mill tailings produced are expected to provide 227 000 t (250 000 tons) annually of backfill, sufficient for Snow Lake mines requirements (H.B.M.&S., 1977 Annual Report).
Ore mined from Snow Lake area mines, in 1983, totalled 826 093 tonnes (910 355 tons) grading 2.57% Cu and 2.80% Zn. The Osborne Lake mine was closed in 1984, but the Rod mine (See: Mind No. 481) started shipping ore to the Snow Lake mill in March 1984, and replaced the loss of Osborne Lake ore (H.B.M.&S., 1983 Annual Report, SEC Form 10-K, CMH 1986-87, p. 188; F.P. Info Service 10/11/86).
