Carbonate rocks of the Nelway Formation (Cambrian) are folded recumbently along a northeasterly axis and overturned to the northwest. These rocks are separated from the Active Formation argillites and limy rocks by the northeasterly trending Black Bluff Fault. Tetrahedrite, minor galena and sphalerite occur in the Nelway breccia, pyrite, sphalerite, galena, chalcopyrite and gold values occur in shears cutting the argillite. Earlier assays of copper stained dolomites indicate the possiblity of a larger lower grade dolomite-breccia hosted silver zone.
