Mineral Hill, Wyoming

Mineral Hill is located in the alkaline intrusive complex of eastern Wyoming and western South Dakota. The project area, located on the eastern Wyoming border, is 25 kilometers west of the Homestake Mine and 20 kilometers west-northwest of Goldcorp’s Wharf Mine. The Mineral Hill project is available for partnership.

EMX is targeting epithermal gold and porphyry copper-gold mineralization associated with an Eocene-age, alkaline intrusive complex consisting of an outer ring complex, interior intrusive complex, and interior breccia zone. Exposed mineralization in the district, combined with historic production from high-grade veins, provides evidence for multiple magmatic events, including the emplacement of a prominent central breccia pipe. Placer gold deposits are broadly developed in and around the Mineral Hill intrusive complex. Reconnaissance drilling has intercepted porphyry-style copper-gold mineralization in an area of stockwork K-silicate and quartz-sulfide veins on EMX’s property.

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