McAdam Mining Corp. property, Chibougamau area, Quebec

The U.S. Bureau of Mines' Minerals Yearbook for 1965, drawing on the Northern Miner, reported the announcement that "McAdam Mining Corp. expects to have its Chibougamau area asbestos property in production by 1967," and that the "total cost of bringing the property to production was estimated to be Can-$17.5 million."² In December of that year Asbestos, the industry's trade journal, wrote that the company "is bringing its Chibougamau area asbestos property into production."¹ For 1970 the yearbook reported that McAdams Mining Corporation "is making plans for developing its property at Chibougamou in northwest Quebec."³ For 1973 it reported that "Rio Tinto Canadian Exploration, Ltd., was evaluating the McAdam Mining Corp., Ltd., property under its option," and described the property, "20 miles east of Chibougamau," as having a "C" zone "containing 105 million tons of ore grading 3.92% fiber and three other zones containing 86.4 million tons of 3.55% ore."⁴ In 1974 "extensive milling and testing were still underway at the Chibougamau mine of McAdam Mining Corp., but at yearend no production decision had been announced."⁵ The yearbook for 1975 said the evaluation and testing of the deposit "were continued by Rio Algom Limited."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
