| 释义 |
The Canadian company LaMancha Resources (TSX:LMA) operates the Hassai open pit mine, and from May, 2011, plans to expand operations, once additional electrical and water resources are in place.[3] Wadi Ariab is oriented E-W. Gold mineralization is associated with a zone of massive sulphide mineraliztion in a marine rhyolite environment. According to Klemm and Klemm, the gold would have been "undetectable to ancient prospectors" due to its "extremely fine grain" nature. Furthermore, "no traces from ancient mining are known", and the 7 current opencast mines were discovered with modern geophysical prospecting methods.[4]See Also
