Nevada Exploration Inc. reported that McEwen Mining Inc. has commenced drilling on the Grass Valley Project in north central Nevada, south of Barrick Gold Corp.'s Cortez Hills Gold Mine. The pre-drilling exploration results at the Project - which included: detailed hydrogeochemistry; vegetation and soil surface geochemistry (including soil gas mercury); the acquisition and reprocessing of two historic seismic geophysical lines; geologic mapping; and a gravity geophysical survey - have provided a strong geologic, geophysical, and geochemical case for a series of drill holes to test for: (a) the depth to reactive lower plate host rocks, and (b) the presence of a geochemically anomalous, hydrothermal alteration system large enough to host a significant Carlin-type gold deposit. Based on these results, McEwen Mining has notified NGE that it has now commenced drilling at the Project.
