Exploration History

1911: Conley deposit discovered by test pitting. 1916: No. 1 shaft sunk about 100 feet east of the Henderson line. 1919: No. 2 shaft was started, 300 ft NE of main shaft. Ore pinched out with depth so subsequent work carried out from No. 1 shaft. 1935: No. 3 shaft sunk near new orebody. 1937: Merger of Conley and Henderson Mines, joined by crosscut from 4th level of No. 1 shaft in the Conley Mine. Old workings on No. 1 and No. 2 shafts now sealed off. 1951-1983: the mine was operated by Canada Talc Industries Limited. 1983: The company was reorganized as Canada Talc Limited. January 1999: Highwood Resources Ltd. acquired Canada Talc. Major mine infrastructure improvements were made including access to new production level and infrastructure and capital equipment installation at mill in Marmora were completed. 2002: Dynatec Mineral Products Division acquired the industrial minerals division of Highwood Resources (see OFR 6152, p2 for details).
