Dugway, Utah

The Dugway project is located ~105 km southwest of the Bingham Copper Mine in the Great Basin of Utah.  There are two porphyry targets located on the property as well as the potential for a telescoped epithermal Au/Ag mineralized system overprinting the porphyry systems.  The host rocks consist of Paleozoic carbonate rocks and the underlying Cambrian Prospect Mountain Quartzite were intruded during the Oligocene. Post-mineral normal faulting has tilted and offset the mineralized system to the southwest.  Alteration is characterized by quartz-sulfide veins hosted in the Cambrian Prospect Mountain Quartzite; and bleaching, recrystallization, and silicification hosted in Paleozoic carbonate rocks.

Much of the historic metal production in the district came from a central horst, having predominantly Cu-Pb-Zn-Au veins on the northwest end of the range, and Zn-Pb-Ag replacements to the south and east. Precious metals mineralization in the district is best observed at the Buckhorn mine. The Dugway project is available for partnership.

Note: The nearby mines and deposits mentioned above provide context for EMX’s Project, which occurs in a similar geologic setting, but this is not necessarily indicative that the project hosts similar tonnages or grades of mineralization
