GRUNERITE Variety Amosite
Penge Mine, Sekhukhune District, Limpopo Province, South Africa

The Penge Mine has been a source of world class examples of the Amosite variety of Grunerite for many years and, at one time, was “the only major producer of Amosite asbestos in the world”.  This is according to J. R. McIver, “Gems, Minerals, and Rocks in Southern Africa”, P. 181 (1967).  According to Wikipedia, the town of Penge was established after Amosite was discovered there in 1907.  The historically interesting specimens available here were acquired from a museum collection, and were recovered from the Penge Mine pre-1970.  These amazing, long-fiber asbestiform examples of the Amosite variety of Grunerite are light grey-tan in color, and were all split from large, very thick, cross-fiber vein material.
