Geologic descriptionA 2- to 5-inch-thick quartz vein(?) with pyrite and chalcopyrite is along a suspected shear zone. The vein is conformable to the bedding of the limestone host rock, which is part of the Wales Group of Late Proterozoic and Cambrian age (Hedderly-Smith, 1999 [Inventory]). A sample contained 4.97 percent copper, 5.4 parts per million silver, and 119 parts per billion gold.
