Djalma Dutra deposits, Bahia

The Djalma Dutra mine, at the place formerly called Poções in the Brazilian state of Bahia, produced chrysotile.^3,5 The U.S. Bureau of Mines' Minerals Yearbook for 1951 reported that "deposits of chrysotile asbestos are worked in a small way at Djalma Dutra, State of Bahia."¹ In 1956 Asbestos, the industry's trade journal, wrote that "the largest asbestos deposits known in Brazil are located at Pacoes, near Jequie, State of Bahia."⁷

In 1959 the journal reported that the producer, S. A. Mineracao de Amianto, "owns the only operating asbestos mine in Brazil, near Djalma Dutra," and gave Brazil's production as "1,545 metric tons in 1958, compared with 675 tons in 1957."² The company's shipments, "all to Brazilan ports," totaled "1,534 tons during 1958 and 715 tons during 1957."² A year later Asbestos said the company "produced 1,882 metric tons of chrysotile asbestos in 1959" and shipped "1,853 tons," again all to Brazilian ports.⁵

The Minerals Yearbook said the mine ran in 1960 "at a somewhat lower level of production than in 1959."³ It reported that deliveries to Brazilian ports "decreased from 1,580 tons in 1960 to 1,292 tons in 1961," printing the company's name that year as "Minevacão de Amianto."⁶ In 1962, the yearbook said, the mine "continued production," and its "sales of chrysotile to Brazilian ports totaled 1,279 tons."⁴

The documents report this mine producing asbestos fiber for sale.²
