This prospect is within the Wilderness of the Admiralty Island National Monument.
Location: The President prospect is at an elevation of about 250 feet, about 1.1 miles north-northeast of Fishery Point on western Admiralty Island. The prospect is on an unnamed south tributary to the west end of Lake Florence, about 0.5 mile southwest of the center of sec. 14, T. 47 S., R. 66 E., It is location 66 of Cobb (1972, 1978) and MAS no. 0021140072 (U.S. Bureau of Land Management, 2002). The location probably is accurate within 0.2 mile (but Williams (1955) could not find it.).
Geology: The rocks in the vicinity of the President prospect are part of the Devonian Retreat Group which consists of schist with marble interbeds (Lathram and others, 1965). There is a small stock of Cretaceous felsic plutonic rocks nearby. Wright (1906) reported 3 quartz 'ledges' and mineralized schist that average 30 feet wide; they are separated by narrow bands of barren schist. The mineralization consists of pyrrhotite, pyrite, and chalcopyrite, with minor galena and sphalerite. As of 1903, the deposit was exposed in open cuts and a shaft was being sunk. Williams (1955) was unsuccessful in a search for the prospect and there has apparently been no work on it since the turn of the 20th century. Although there is scant information on this prospect, the rocks may be the same age as the nearby and well-known Greens Creek Mine (Barnett and Miller, 2003; ARDF JU253).
Workings: Open cuts and a shaft prior to 1904.
Age: Devonian or younger based on the age of the host rocks.
