DESCRIPTION OF DEPOSIT
The North Star deposit occurs in cherty, chloritic schist, adjacent to Aphebian “rhyolitic quartz porphyry” and andesite. The main, massive orebody strikes north for 76 m (250 ft.) averaging 6 m (20 ft.) wide. It extends to the 137 m (450 ft.) level from surface, plunging and dipping vertically.
Massive chalcopyrite comprises the northern, upper part of the main orebody. Sulphides fill irregular fractures to the southeast and beneath the massive zone. Pyrite forms coarse grains with silica, chorite, and carbonate. Chalcopyrite is usually finer-grained and may replace pyrite and the gangue minerals.
ASSOCIATED MINERALS OR PRODUCTS OF VALUE
Gold (Au) and silver (Ag).
HISTORY OF EXPLORATION AND DEVELOPMENT
The deposit is located below the southwest portion of Thompson Lake, between two small islands. David Collins first staked the property as Renaann (29401), on August 4, 1919. On September 5, 1919, the claim was transferred to H.F. Bickle. Minor work was done before the property was cancelled in 1920.
Part of the Renaann claim was restaked as Thompson (34438) on July 29, 1922, by A.L. Stewart. In 1922, Stewart transferred one half of his interest to F. Hazen and one quarter of his interest to R. Hassett. From 1923 to the time of cancellation in 1928, a series of small test pits were made on the property. Stewart restaked the property, again as Thompson (17999) in 1929, The claim was cancelled in 1935.
On March 16, 1938, W. Govin staked the property as Wedge (4193), but the claim was allowed to lapse in 1945.
Part of the property was also staked as Bridge 5 Frac. (4208) in 1938, by R.A. McCellan. All interests were assigned to W. Roberts in 1938, and the claim was allowed to lapse in 1947.
The present Baker 5 (P17367) claim, was staked on October 18, 1947 by R.D. Miller. All interests were transferred to the Hudson Bay Exploration and Development Company Limited (HBED). The company carried out diamond drilling operations from 1949 to 1951, during which time, the orebody was discovered and outlined. By 1950, drilling by HBED indicated 141 500 tonnes (156 000 tons) averaging 6.78% Cu.
Development began in 1951. A road and power transmission line were extended to the property. Shaft sinking commenced in 1951 and advanced to 495 m (1623 ft.) by the end of the following year. Water in the shaft hindered development.
During 1953 to 1954 development ore was hoisted and stockpiled. Dams were constructed and the lake was partially drained. A crosscut on the 180 m (600 ft.) level was extended 495 m (1620 ft.) to the Don Jon orebody (See: Mind No. 694). Don Jon was mined through the North Star shaft. Lease M-3650 was issued in 1954, and the claim was assigned to Hudson Bay Mining and Smelting Co. Ltd. Full production began January 1, 1955. All ore was trucked to Flin Flon for treatment. The shaft was deepened in 1956 to 304 m (996 ft.) Production ceased March 31, 1958, when the orebody was mined out. The property has been idle since that time.
HISTORY OF PRODUCTION
Production began in 1954, and ended in 1958 after the orebody was exhausted. The following production figures and grades were gleaned from the annual reports for HBMS.
