Abstract

The Cerro Casale and Caspiche gold-copper deposits are located in the Maricunga Belt of northern Chile, 110 km southeast of Copiapo.

The Maricunga Belt encompasses numerous large hydrothermal alteration zones hosted by volcanic rocks and high level stocks which intruded them. Mineralization includes gold +/- copper-rich porphyry and precious-metal epithermal styles, formed during late Oligocene and Miocene hydrothermal events. Both deposits were discovered in the 1980’s and have undergone extensive exploration. Currently, the two deposits form part of the Norte Abierto JV between Newmont Goldcorp and Barrick Gold.

In these two alteration reports, PhotoSat produces alteration mineral maps from WV-3 and ASTER satellite imagery for the area around the two deposits.

For results, read the full alteration report.
