Report: St. Anthony-Twohy Roby and others (1960) described this small mine with no recorded production. Workings consist of adits: two caved adits, an open adit, and a caved shaft, with a total length of less than 700 feet. They mined a vertical N87W black quartz vein 2-4.5 feet wide for 200 feet of strike length. Host rock is quartz monzonite with some disseminated galena near the vein. One adit discharges water; a composite sample of the associated dump ran .007 oz/ton gold, .54 oz/ton silver, .044% copper, .760% lead, and .663% zinc.
