Geology

Host rock:Pilot Shale
Host type:Shale,Limestone
Associated rock:Bald Mountain Stock
Associated type:Granite
Structure:The dominant structural trend is N45W, but there are NE, N-S, and E-W-trending structures as well. The E-W structures show the youngest period of movement, some of which is post-ore.
Alteration processes:Silicification, argillization, and potassic alteration have affected the host rocks. The main alteration feature is the large halo of silicification and strong argillization. Potassic alteration is recognized at depth.
