Montezuma Porphyry Copper
Project Category: Exploration
-
OVERVIEW:
The Montezuma copper-gold-molybdenum project comprises approximately 45,000 Ha of 100% owned tenement. The Project is located along the main porphyry copper belt in northern Chile, commonly known as the Domeyko Cordillera, directly along the main West Fissure Fault System that controls several world-class copper deposits in the area, midway between the giant Chuquicamata (Codelco) and Centinela (Antofagasta Minerals / Marubeni Corporation) copper mining districts. The Project is centred approximately 20 km south of the important mining town of Calama. Access to the Project is excellent via a series of good quality dirt roads leading off from paved roads around Calama, and altitudes vary from approximately 2,600 m to around 3,100 m. Historical drilling of ~35,000m has been completed on the property.EXPLORATION HISTORY:
Two significant exploration campaigns have been completed at Montezuma over the past 10 years:
> From late 2007 to early 2014 Polar Star Mining Corporation (“PSM”) focused on targets associated with the West Fissure Fault Zone in the central part of the project area. This included more than 26,000 meters of drilling and led to the discovery of a series of hydrothermally altered porphyries and breccias with highly anomalous intercepts of copper and gold mineralization, including 44m @ 0.55% Cu + 0.17g/t Au (MODD38-10 – Anomaly B), and 38m @ 0.17% Cu + 0.44g/t Au (MODD45-10 – Anomaly B).
> Between 2014 and 2016 Minera Newmont (Chile) Ltda., a subsidiary of Newmont Mining Corporation (NYSE: NEM), under a JV agreement with and Revelo Resources Corp (TSX-V:RVL), focused a majority of its work on targets associated with the Sierra Limon Verde Fault Zone in the western part of the project area, together with targets in covered areas to the north. This work included ~8,500 meters of drilling.KEY TARGETS:
The Melissa target, in the northeast of the Montezuma project area, is a broad area with a series of sub-targets. Hydrothermal alteration and associated Cu-Mo geochemical anomalies extend over approximately 5 km x 5 km, with associated precious metals anomalies likely related to an epithermal overprint, as evidenced by 139.5m @ 0.46g/t Au in hole MM11.GEOLOGY:
The main host rock is an equigranular, Palaeozoic-aged granitoid. Widespread propylitic alteration is overprinted by green-clay alteration, localised tourmaline alteration, hematisation of feldspars and abundant leucoxene, a bi-product of mafic mineral destruction. Porphyry-style sheeted quartz veinlets occur in some locations. Further work is required to vector into, and locate, a causative body for the alteration and mineralisation encountered.OPPORTUNITY:
The project is held by Revelo Resources Corp (TSX-V:RVL) and is available for Option or JV. -
