Mineralization is a vein that dips steeply to the south or stands vertical. It ranges from 8 inches to 2 feet (20 to 60 cm), and in some places has good walls. The filling is apparently brecciated diorite and quartz, the whole being very much stained with iron and manganese oxides and lead carbonate. It shows a little galena coated with earthy carbonate and is said to carry horn silver, bromargyrite and native silver.
Workings include 2 shafts and a cut. The main shaft is 110 feet deep, with a 20 foot drift to the east on the 70 level and 2 drifts on the 100 level. The shaft to the northwest of the main shaft is 25 feet deep and is said to have been sunk on a pocket of rich silver ore ($240 Ag/T [period values]).
