Geology

Host type:	Claystone
Structure:	Two Fault Sets Define Local Structure. An Older Set Of Nnw-Striking Normal Faults Are Downthrown On The West. This Fault Set Appears To Be A Primary Control Of Gold Deposition. A Younger Ene-Striking Range Front Fault Set (E.G. Crescent Fault) Offsets The Older Set And Serves To Localize Mineralization At Structural Intersections.
Alteration processes:	Pervasive Cristobalite-Alunite Associated With Smectite Is Thought To Result From Acid Leaching Of The Deposit During The Last Stages Of Hydrothermal Activity. Lesser Silicification And Possible Decalcification Of Host Rocks.
