Comments on the geologic information

  • Geologic Description = 'Host rocks are interbedded graywacke and shale of the Kuskokwim Group cut by a few dikes that are generally altered to quartz, chalcedony, carbonate, and sericite (Malone, 1962). Most of the ore formed along and near intersections between altered dikes and NW-trending faults that mainly parallel bedding planes. Formation of ore was primarily by open space filling and consists of cinnabar associated with abundant stibnite in a quartz-rich gangue; less common realgar, orpiment, and antimony minerals are also found (MacKevett and Berg, 1963). Stibnite-cinnabar ratio increases with depth (Malone, 1962). Ore shoots did not continue below 460-480 ft (Donald Grybeck, USGS, personal commun., 1988). MacKevett and Berg (1963) reported that clay minerals (dickite among them) occupy central parts of some ore-bearing veinlets, but are more conspicuous in barren veinlets away from ore bodies. Jasper (1961) stated that while no native mercury was found at the property, old timers reported appreciable amounts in material panned along McCally Creek, west of the property.' (Miller and others, 1989).
