The Mineral vein is located in the northern part of the Alto property, has a known length of about 900 feet. It seems to lie chiefly in granite porphyry. It is about 3 feet wide, dips steeply to the south, and consists of a lode of quartz stringers in altered rock. Both the rock and the quartz contain ore, and much ore has been gouged out from the vein and a spur vein just to the east across the gulch from the east workings.
The ore consists of sulphides, copper carbonates and iron oxides.
Workings include a 100 foot tunnel and several shallow shafts, each about 40 feet deep.
