Location: This occurrence is at an elevation of about 4,600 feet on a northeast facing slope about one-third of a mile north of hill 5330. It is in the NW1/4SE1/4, section 19, T. 14 N., R. 7 E. Copper River Meridian.
Geology: This copper occurrence is on the projected trend of Richter's Jurassic diorite to quartz diorite complex (1966; also Richter and Matson, 1968) but the bedrock at the occurrence is unknown. A chalcopyrite occurrence was reported here by WGM Inc. (1980, fig. 3). No other data is known on the occurrence. See also GU039 which is nearby.
Workings: Probably only natural exposures.
Age: Possibly associated with emplacement of Richter's (1966) Jurassic quartz-diorite complex.
