The GC showing occurs in an area of poor bedrock exposure on the Chilcotin Plateau and the geology of the area is imperfectly known. Recent mapping (Geological Survey of Canada 91-1A) indicates that the area is underlain by hornblende quartz monzonite, quartz diorite and diorite of the Middle Jurassic Mount Alex plutonic complex overlain to the east by mainly subaerial basalt flows of Miocene or Pliocene age (Chilcotin Group).
Mineralization of the showing is reported to comprise copper in an extensive pyrite zone; no additional information is available.
