Concepcion Papalo mine and mill, Cuicatlan (printed "Quicatlan") District, 100 km northwest of Oaxaca, Oaxaca

Concepcion Papalo was a planned chrysotile mine and mill in the Cuicatlan District, "100 kilometers northwest of Oaxaca," in Mexico.² Asbestos, the industry's trade journal, reported in 1975 that it was expected "to be on stream in 1978, capable of producing some 60,000 short tons of fiber per annum," and repeated that plan in 1977.^2,3 In 1978 it said development was "still at the pilot plant planning stage."⁴ In 1979, quoting the Mining Annual Review, it reported a pilot plant "erected at its Pegaso, Oaxaca, asbestos deposit by Industrias Penoles, in a joint venture with Johns-Manville Corporation."⁵ In January 1981 it called Concepcion Papalo "a $44-million asbestos project" of the Pegaso company, owned 60% by Penoles and 40% by Johns-Manville, "expected to soon come on stream."¹

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
