| Deposit | The deposit is a replacement vein in dark gray, finely crystalline limestone and finely laminated siliceous shale of the Ordovician Aura Formation. Galena, pyrite and iron oxides occur in a white quartz vein with minor amounts of sphalerite and tetrahedrite. The vein also contains boxwork pods of iron and copper oxides. The limestone in the mine area is cut by abundant white calcite veins. Much of the mine dump rock consists of brecciated white vein quartz recemented by silica and iron oxides. Smaller workings in the vicinity of the main shaft are aligned along a fault striking N54E. |
