Location and accuracy Granite Creek probably carries minor amounts of gold widely and it was prospected for several seasons prior to about 1940. The main activity was near the intersection of Granite Creek and the West Fork of Granite Creek in the W1/2, section 6, T. 13 N., R. 7 E., Copper River Meridian. The location is approximately the same given as locality 19 by Richter and Matson (1972) and locality 18 of MacKevett and Holloway (1977). The location is approximate.

Geologic setting

Geologic description

Granite Creek mainly flows on the dioritic phase of the Pennsylvanian to Permian, Ahtell pluton and sedimentary and volcanic rocks of the Pennsylvanian to Permian, Slana Spur Formation (Richter, Lanphere, and Matson, 1975). Granite Creek was sufficiently auriferous to be prospected for several seasons before World War II (Moffit, 1938, p. 51). Production, if any, was small. The placer is probably of river-bar type.
