Asbestos Corp. mines, Quebec

These are the Quebec mines of Asbestos Corporation, which the U.S. Bureau of Mines' Minerals Yearbook speaks of together, without naming each mine: drawing on the Northern Miner, the yearbook for 1955 counted "increased ore reserves" and "greater production at the mines of Asbestos Corp. in Quebec" among the signs of optimism about Canadian asbestos.³ For 1959 it reported that overproduction and large inventories in the industry brought "seasonal shutdowns at mines of Asbestos Corp., Ltd., and Johnson's Co., Ltd."⁴ In 1962, the yearbook says, the company "exchanged shares equivalent to a 10-percent interest with Eternit S.A. of Belgium," and the agreement included "a long-term contract for purchase of asbestos from the Canadian company."¹ That year "a total of 4.6 million tons of ore was milled, and 10.9 million tons of barren rock excavated."¹ In 1964, citing the Engineering and Mining Journal, the yearbook reported that Asbestos Corp. and Johnson's Co., Ltd., "announced an agreement to integrate their operations in the Thetford-Black Lake region of the eastern townships."²

The documents report this mine producing asbestos fiber for sale.³

Figures as printed, in the units each document uses (short tons before about 1990, metric tons after, in most U.S. chapters). Some are a year's output, some a daily rate or a capacity, some a company's total rather than this mine's alone; the statement for that year below says which.
