Garrison Township property, Garrison Township, about 13 miles east of the Munro mine, Ontario

Canadian Johns-Manville's Garrison Township property in northern Ontario lay "about 13 miles east of the Munro mine," according to the U.S. Bureau of Mines' Minerals Yearbook for 1964, or "about 25 miles east of Matheson," according to its yearbook for 1969.^2,3 In 1952 Asbestos, the industry's trade journal, reported that the company had "completed their drilling campaign on the Byrd group of claims," and a 1954 article said it bought "the Bird-Ginn asbestos ore property" in 1952, "some 27 miles east of Matheson," without naming the township.^1,4 The yearbook reported bulk sampling and drilling in 1964 and "underground exploration" in 1969.^2,3 In 1971 both sources said the orebody had proven "commercial potential," and the yearbook said it was "on standby status pending need."^5,6

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.⁵
