Geology & Mineralization

Mineralization is hosted in the Triassic Star Peak Group, a 1,220 m thick section of marine platform limestone with lesser conglomerate, sandstone, and dolostone (Johnston 2008). Four formations comprise the Star Peak Group. In ascending order they are: the Dixie Valley, Favret, Augusta Mountain, and Cane Spring Formations. Most of the historic production came from the Augusta Mountain Formation.

A trident of known deposit types exist on the property, including skarn, distal-disseminated polymetallic sulfide, and distal Carlin-style carbonate-replacement opportunities. Deeper high-grade gold/silver target areas exist between the McCoy and Cove open pits along known feeder fault structures. IP Resistivity geophysics has been used to aid in defining sulfide concentrations and rock alteration at depth. High-grade gold mineralization is also known to exist in the Panther Canyon conglomerate down-dip along the Gold Dome intrusive fault structure at the McCoy pit area. This high-grade mineralization is undrilled at depth and represents one of the highest quality deep targets.
