Geologic description

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.
