Structure: Fractures, Slickensides
Alteration: Kaolinization Of Wallrock Near Veins; Silication
Deposit: Workings explore quartz veins along shear zones in diorite and hornfels. Eastern shaft is in diorite; western shaft has diorite on east wall, hornfels on west. Veins are mostly white quartz, but are brecciated and recemented with quartz and hematite. Wallrock kaolinized near veins. Clots of pale green crystalline mineral (arsenate?) coat fracture surfaces, slickensides on fault surfaces.
Deposit type: Low-sulfide Au-quartz vein
Development: Inactive in 1984
Geology: The top of the small hill at the prospect is underlain by diorite, silicated rocks lie both east and west of the diorite
Rock formation(s): Auld Lang Syne Group
Ore(s): Shear Zone
