Location: The Harvison prospect is on a north-trending ridge near hill 1,050, about 2.2 miles south of the mouth of the East Fork of the George River. The prospect is in the SE1/4 sec. 25, T. 22N., R. 46 W., of the Seward Meridian. The prospect is locality 3 of Miller and others (1989). The location is accurate.
Geology: The Harvison prospect consists of lenses and pods of quartz and cinnabar in silicified, argillaceous sandstone of the Upper Cretaceous, Kuskokwim Group (Cady and others, 1955; Jasper, 1963). The sandstone layers near the prospect are cut by a weathered dike or sill of unknown composition. The mineralized zones are 2 to 4 inches thick and are commonly associated with silicified fault breccia. No other information is available.
Workings: John Harvison discovered the prospect prior to 1963 by panning soils on the hill slopes nearby as well as stream gravels of nearby tributaries to the George River. By 1963, his development work consisted of a trench about 30 feet long and a 3-foot pit (Jasper, 1963).
Alteration: Silicification of sandstone in the area.

Commodities (Major) - Hg
Development Status: None
Deposit Model: Silica-carbonate mercury? (Cox and Singer, 1986; model 27c).
