Structure: Steep n-s striking faults offset the mineralized ne-striking faults. A young, less than 3 ma old, broad regional upwarp extends form the southwest of the bodie hills through the bodie district to the area of the aurora district. This upwarp may continue to the northeast, south of the borealis mine.

Alteration: Progressive weak propylitic, strong propylitic, quartz-illite alteration surrounding silicification in the mineralized faults.

Deposit type: Epithermal vein, Comstock

Ores(s): Ne-striking faults occupied by quartz-adularia (+au +ag) veins. Three stages of veining are recognized. Precious metal deposition is associated with the second stage of veining, probably during boiling of the hydrothermal fluid.
