Jacob's mine (Consolidated Asbestos), Thetford Mines, Quebec

Jacob's mine was an asbestos mine at Thetford, Quebec, worked by the Jacobs Asbestos Mining Company and later by Consolidated Asbestos Limited: in 1921 Asbestos, the industry's trade journal, wrote of "the Consolidated Asbestos Limited mine at Thetford (formerly the Jacob's Mine)," where "underground haulage is done by storage-battery locomotives, with charging installation underground."¹ A 1925 profile of an engineer named Wilson in the same journal said that his first work was for the Jacobs company, "where he put in underground works at the mines at Thetford," along with "a new hoisting and drying plant, the first time this method had ever been used in the mining of asbestos."² The system, it said, was "still being used at the Thetford mine."² A visitor writing for Asbestos in 1925 found "the Consolidated Thetford property" to be "working on the old schedule."³

The documents report work here (mining, shafts or a mill) but no fiber sold or shipped; that is what our documents say, and the mine may still have sold some.¹
