The Avispa Copper Project license application is located in the Atacama region of northern Chile, west of the town of Calama and 220km north east of Antofagasta, Chile’s largest commercial deep-water port. The project is in the Atacama Region and is connected by asphalt road to the ports of Tocopilla and Antofagasta.
Montero has applied for 132km2 of Exploration License in an almost contiguous area south of the main highway between Calama and Tocopilla. Part of the area was previously held by Spence Mining a subsidiary of BHP.
The Avispa copper project area was previously held by Spence Mining, a subsidiary of BHP, that was exploring for porphyry copper-molybdenum mineralization in the area. It has seen previous exploration with approximately 20 diamond drill holes have been observed in the application area.
The Avispa copper project occurs geology along the north – south trending Paleocene Cu-Mo porphyry belt which is termed the Sierra Gorda-Spence-Cerro Colorado porphyry copper-molybdenum belt. The project area is 40km north of BHP’s Spence Cu-Mo mine and of KGHM’s Sierra Gorda Cu-Mo mine. The project is 8km south of Chug-Chug porphyry system which shows Qz-Ser-Tur breccias and copper oxide mineralization on surface.
