DESCRIPTION OF DEPOSIT
Massive and disseminated sulphides occur in a tabular orebody in Precambrian Kisseynew-type quartz-biotite gneiss, which strikes N45E and dips 65NW, along the Berry Creek fault, on the eastern flank of a syncline. The orebody is 274 m (900 ft) long and averages 6 m (20 ft) in width. Along its plunge of 30SE, it is 1097 m (3600 ft) long. The coarse-grained ore contains pyrite, pyrrhotite, arsenopyrite, chalcopyrite, sphalerite, with minor bornite, cobaltite, galena, titanite, marcasite, and garnet. An older, less prevalent phase consists of fine-grained pyrite and arsenopyrite. Gold and silver were found in assays.
Both the ore and wallrock are intruded by coarse-grained, sheared pegmatite.
This deposit is listed in a table of volcanic-hosted ore deposits (Walford and Franklin, 1982, p. 484).
ASSOCIATED MINERALS OR PRODUCTS OF VALUE
Zinc, gold, silver
HISTORY OF EXPLORATION AND DEVELOPMENT
The deposit is located 1.2 km north-northwest of the north end of Osborne Lake. The C.N. railway spur from Stall Lake and Provincial Road 393, end at the mine.
The Lakeside, Lakeview, and Great Bear Groups were staked here, during the late 1920's. According to Russell (1957), a mineralized Cu-Zn zone at Osborne Lake was staked in 1914 (unconfirmed). At least 122 m (400 ft) of trenching was done. Assays of up to $8.90 for Cu, with minor Au and Ag were reported (Manitoba Miner, March 15, 1928). The discoveries were made by Mr. Stewart and J.H. MacKay (Northern Mail, March 14, 1929). Two mining engineers, Bull and Crago, reported favorably on the deposit consisting of 14 claims and 1 fractional claim. The Lakeside Group of 11 claims were transferred from Edgar Stewart, to a syndicate represented by Jack Bull (Manitoba Mines Branch b). Canam Metals Limited optioned, and then purchased the claims in 1929, through their representative, J. Ellis. Diamond drilling commenced in June 192, but the results of this work is not known.
Pine Lake 1 and 2 (P7136, and P7137) were staked by R.W. Bryerton in 1944. Surface work was probably done in 1945, and the claims were cancelled the following year.
G.D. Tribble staked T.K. 1, 2, 7, and 8 (P 19207, 8, 13, and 14) in 1948. A magnetometer survey found several anomalies. Three holes totalling 48 m (157 ft) were diamond drilled on T.K. 1, 9, and 15 for Wekusko Consolidated Limited (Non-confidential Assessment File No. 90081). A 19.8 m (65-ft) hole on T.K. 1 intersected a section, which assayed 0.06% Cu, 4.07% Zn, 5.49 grams/tonne (g/t) (0.16 oz/ton) Ag, and trace Au. A grab sample from an old trench yielded 2.22% Cu. A selected sample from an outcrop assayed 0.51% Cu, and 2.20% Zn (Non-confidential Assessment File No. 90081). T.K. 2 and 8 were cancelled in 1949, and T.K. 1 and 7 were also cancelled the following year.
01, 03 and 05 (P22352, P22354, and P22356) were staked, in 1950, by Mike Remniak, P. Kobar, and W.B. Kobar, respectively. In 1951, Remniak assigned his claim to Pete Kobar, Kobar also staked Pine 16 (P23584) that year. One 10.7-m (35 ft) hole was diamond drilled on each of the 0 claims in 1951. Hudson Bay Exploration and Development Company Limited (HBED) optioned the property in 1952. A ground electromagnetic survey was completed and diamond drilling began. By the end of 1953, HBED had drilled 1568 m (5143 ft) on 01 and 1594 m (5230 ft) on 03. In 1954, HBED. exercised its option and purchased the claims.
According to the 1954 Annual Report of HBED’s parent company, Hudson Bay Mining and Smelting Co. Limited (HBMS), drilling and geophysics outlined 300 000 t (330 000 tons) averaging 3.97% Cu and 1.7% Zn. In 1955, reserve estimates were raised to 402 000 t (443 000 tons) grading 4.01% Cu and 1.7% Zn. Exploration diamond drilling amounted to 4656 m (15 276 ft) throughout the Osborne Lake property that year (HBMS, 1955 Annual Report). Leases M3759-61 and 3792 were issued for 01, 3, and 5, and Pine 16, in 1955. The following year all the claims were assigned to HBMS.
An airborne electromagnetic survey was done by Canadian Nickel Company Limited, under Airborne Permit No. 19, in 1957 (Non-confidential Assessment File No. 91624).
In 1961, surface leases M-100, M-111, and M-136 were issued for 03, 05, and Pine 16. The road and power transmission line was completed to the mine site. A three compartment service shaft on 03 was collared and sunk 15.8 m (52 ft). The sinking of this shaft ended in 1965, at a final depth of 679 m (2229 ft). Twelve levels, roughly 46 m (150 ft) apart, were established. The highest level is 76 m (250 ft) below surface, and the deepest is at 640 m (2100 ft). A short drift was driven on the 533 m (1750 ft) level, in 1963. Exploration diamond drilling totalled 271 m (889 ft) in 1963, 1973 m (6473 ft) in 1964, and 5728 m (18 793 ft) in 1965. In 1964, 594 m (1950 ft) of drifting was done on the 183 (198?) m, 305 m, and 579 m (600 (650?) ft, 1000 ft, and 1900 ft) levels. Between 122 m and 244 m (400 and 800 ft), 363 000 t (400 000 tons) of blocked ore grading 4% Cu and 2% Zn was reported (Northern Miner, September 10, 1964). Proven reserves of 2 .2 million tonnes (2.5 million tons) to the 610 m (2000 ft) level, but open at depth were reported to average 4.5% Cu and 1.6% Zn (Northern Miner, May 13, 1965).
The three compartment production shaft was collared on 05, in 1965, and sunk to 72.5 m (238 ft) that year. It was completed to 732 m (2402 ft), by the end of 1966 In 1996, proven reserves totalled 2.3 million tonnes (2.5 million tons) grading over 4% Cu and 1.4% Zn (The Northern Miner, October 3, 1966).
The C.N. railway from Stall Lake to Osborne Lake was completed in 1967. during 1967 and 1968 exploration diamond drilling totalled 9057 m (29 714 ft) and development work continued.
As of January 1, 1968, proven reserves were 2 467 150 t (2 718 800 tons) grading 4.17% Cu and 1.4% Zn (World Mining). The Osborne Lake mine was brought into production on July 2, 1968, using ore from underground and from the development stockpile. The production rate was approximately 726 t/day (800 tons/day). During 1968, exploration drilling outlined an additional 67 000 t (74 000 tons) of ore grading 6.2% Cu and 1.4% Zn (HBMS, 1968 Annual Report). See History of Production for yearly production figures. By 1970, the mine was producing at 1089 t (1200 tons) per working day (Hawkins & Martin, 1970).
In 1971, drifting was done on the 640 m (2100-ft) level. Drilling found the orebody to extend at least 91 m (300 ft) below that level. Production halted in March of 1973, in order to develop the deeper zone below 640 m. The production, or #2 shaft, was sunk another 168 m (550 ft) and two new levels at 701 m, and 823 m (2300 ft and 2700 ft), were started. The #1 (service) and #2 (production) shafts were connected on the 533 and 640 m (1750 and 2100 ft levels).
As of January 1974, reserves at the Osborne Lake mine were 1 747 000 t
(1 925 200 tons) grading 3.64% Cu and 1.5% Zn (Cranstone and Hamilton, 1976). During 1974, a total of 197 000 t (217 000 tons) were added to the reserves in the ore zone below the 640 m level (HBMS, 1974 Annual Report). Underground diamond drilling totalled 1227 m (4027 ft) that year. Stopes were developed in 1975.
Diamond drilling from the 838 m (2750 ft) level confirmed a limited tonnage of ore below the bottom level (HBMS Annual Report 1978). Further drilling, in 1979, failed to prove up additional ore and a start was made on development of the lower ore zone (HBMS, Annual Report 1979).

The mine ceased production temporarily in the fall of 1983, and permanently closed in 1984 (HBMS, Annual Report 1984).
As of December 31, 1984, the mine was reported to contain ore reserves of 528054 t grading 2.45% Cu and 1.28% Zn (Esposito, 1986, p. 12). Total production and reserves were reported as 3 380 000 t grading 3.03% Cu and 1.48% Zn (Bamburak, 1990, p. 7).
A bedrock-sampling program was done by Eccles and Fedikow (1985) and an industrial minerals study was done by Gunter and Yamada (1985). It was noted that the mine dump was a potential source for garnets.
In 1993, MMR, in joint venture with HBED, conducted a drilling program on the Bur zone near the mine site, some encouraging results were encountered in these shallow drill holes (Northern Miner, March 28, 1993)
As of 2002, no further work has been done on this deposit.
