Campomento deposit, Colombia

The Campamento deposit, printed "Campomento" in one source, was in the Department of Antioquia, Colombia, and the sources tell of it only as a project of Nicolet Industries.^1,2 In December 1970 Asbestos, the industry's trade journal, reported that Nicolet Industries, Inc., had "received approval from the Republic of Colombia to develop an asbestos mine in the remote mountainous section of the Department of Antioquia," a report that names no place more exact than that.³ A year later the trade journal wrote that Nicolet would "provide foreign capital to develop an asbestos property at Campamento," that "Compania Minera Emmo S.A. holds a 30% interest in the development project," and that "the deposit has proven ore reserves of 280,000 tons plus 420,000 tons of probable ore reserves."² The U.S. Bureau of Mines' Minerals Yearbook for 1971 gave the same reserves, and said Nicolet "was building a mill."¹ The two sources gave different plans for the output: the trade journal said "production is scheduled to commence in 1973 at an expected annual rate of 25,000 metric tons," while the yearbook said Nicolet "expects to be in production in 1973 at a possible 60,000 tons of fiber per year rate."^1,2 Neither source says whether production began.^1,2

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

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.
