Exploration and Mining History

Gold mineralization was found in 1929 and was explored by Casey Mountain Operating syndicate between 1929-1931. Approx 610 m of diamond drilling was completed and the No.2 shaft on the No. 2 vein was sunk to 25.9 m. Casey Summit Mines was incorporated in 1931 and in 1933 and 1933 No.2 shaft was deepened to 97.5 m, 551.7m of lateral development was completed, and a 50 ton per day mill was installed. Production was limited to this point and in 1935, Argosy Gold mines Ltd was formed to continue development on the property. The workings were dewatered and 125 ton/day mill was erected. Production continued from 1936-38. Argosy Gold Mines went bankrupt in 1938. Jason Mines Ltd acquired the mine and 22 surrounding claims in November 1938. The No. 1 shaft was sunk approx 457 m E of the No. 2 shaft. No production was recorded at this time. Shut down in October 1942. Jason Mines Ltd resumed operations in 1946-47. In 1948 Jason Mines Ltd, changed to New Jason Mines Ltd and resumed production in 1949. The known ore reserves were depleted in 1952 and the mine was closed in April 1952. Property was dormant until 1974 when Casummit Lake Mines Ltd optioned the property. 5 DDH totalling 490 m on the No. 5 vein system. 1975 Grand Bay explorations conducted DDH program in 1978, DDH3 assayed 300 g/t over 0.3 m at depth 61.3 m. Noranda Exploration Company Ltd 12 DDH totalling 1188 m in 1986. Goldfields Canadian Mining Ltd carried out DDH in 1988 and 1989. Wolfden Resources Inc, acquired the property in 1999 carried out an environmental assessment. Cangold Ltd drilled a 9 DDH program totalling 1513 m in 2001-02. 2003-04 Cangold Ltd. completed a 14 DDH exploration program.

Geology Comments

07/15/2014 (T Pettigrew) - A synclinal structure of interbedded and generally east-trending greywacke, quartzite, slate, iron formation and pyroclastics is surrounded by Keewatin intermediate to mafic lavas. The rocks have been intruded by occasional diorite and granite dykes. Most of the veins occur in N-S fractures dipping 30-85 to the west. Quartz is associated with variable amounts of arsenopyrite, pyrrhotite, chalcopyrite, pyrite, sphalerite, galena and native gold. Underground workings opened up initially veins No. 2 and 3, the width of which ranged from 2 to 7 and 1.5 to 4 respectively. In 1938, development work was also started on vein No.1. The average grade of the ore mined was 0.37 oz/t Au (Ferguson et al., 1971).
