Asbestos Colombianas find, Department of Antioquia, Colombia

The U.S. Bureau of Mines' Minerals Yearbook for 1973 reported that Asbestos Colombianas, S.A. and Nicolet Industries, Inc. were "raising its sights from 25,000 tons per year to 60,000 tons per year of fiber from its find in the Department of Antioquia," in Colombia, and that "reserves are estimated at 18.2 million tons of 4.3% fiber content."² The yearbook for 1974 reported that "Eternit Colombiana has purchased the 70% interest of Nicolet Industries, Inc., in the Las Brisas asbestos project," and that the mine was "now expected onstream in late 1976," a plan rather than an opening.¹

The documents describe this as a deposit or prospect: they report exploration or describe the deposit, not mining for sale.²
