Köppen climate type:
A silver mine on Mt. Chopaka west of Nighthawk. It was developed by 3 adits containing 2000' of workings. A few cars of ore were produced before 1911.
Structure: The Kobau Formation Was Deposited Along An Active Continental Margin Proximal To An Island Arc.
Deposit: Three adits totaling 2000 feet were driven (rinehart and fox, 1972). ; info.src : 1 pub lit
Geology: The kobau formation is intruded by granodiorite and tonalite of the triassic-jurassic loomis pluton. Mineralization is present in a west-northwest trending-fault near the contact (rinehart and fox, 1972, geol. Map).
Ore(s): The Deposit Is On The Same Fault And Is Similar To The Ruby Deposit. The Vein Trends N65w, Dips 35sw, And Can Be Traced For 3000 Feet Along The Outcrop. The Vein Is Altered As Much As 4 Feet From The Fault (Huntting, 1956, P. 307; Rinehart And Fox, 1972, P. 96).
