Ore controlMuch of the gold mineralization occurs in bedding-parallel zones in shale and siltstones, as well as in NW-trending high-angle structural zones cutting shale, siltstone, and limestone.

Geology
Host rockShale,Siltstone,Limestone · "Candland Formation", "Windfall-equivalent formation"
Associated rockQuartz Monzonite,Dolomite · "Kinsley stock", "Lamb Dolomite"
StructureNW-trending high-angle structural zones. Alter, post-mineral N-S trending Basin and Range type faulting., The Kinsley Mountains are situated along teh southern flank of the Tooele Arch, an early Paleozoic uplift.
Tectonic settingSevier Thrust Belt
AlterationAlteration associated with gold mineralization consists mainly of silicification, oxidation, and decarbonatization with minor argilllization and local quartz veining. Skarn formation is associated with intrusive activity in the southern part of the property and silicification and with range-front faults. Widespread bedding parallel replacement silicification forms a widespread jasperoid body that is intermittently exposed over several square miles at the contact between the Lamb Dolomite and the overlying Candland Formation. Rocks are bleached adjacent to structures.
