Geology

Host rock:	Candland Formation, Windfall-equivalent formation
Host type:	Shale,Siltstone,Limestone
Associated rock:	Kinsley stock, Lamb Dolomite
Associated type:	Quartz Monzonite,Dolomite
Structure:	NW-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:	Sevier Thrust Belt
Alteration processes:	Alteration 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.
