Maple Leaf Asbestos Corporation mine, Quebec

In October 1925 a visitor's account of a trip through the Canadian asbestos district, written for Asbestos, the industry's trade journal, reported that the Maple Leaf Asbestos Corporation "has lately installed a steam shovel and otherwise improved their plant."¹ The visitor wrote that "they are running double shift," and that it was rumored the plant's capacity would be increased "should it happen that the proposed merger does not go thru."¹ In 1930 an advertisement by Asbestos Corporation Limited, listing the material hoisted in one day at "the Corporation's various mines," gave the Maple Leaf Mine "755 tons."² The corporation's annual report for 1937, as the trade journal printed it, said the Maple Leaf mill ran "for six months" of that year.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.³

Output the documents report

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.
