Morros Blancos

The Morros Blancos project lies within the Paleocene Central Belt of northern Chile that hosts important porphyry copper deposits, such as Cerro Colorado, Spence, Sierra Gorda, and Relincho. Morros Blancos is within 10 km of the Amancaya epithermal gold-silver mine and 55 km southwest of the Guanaco gold-silver mine. Morros Blancos is an early-stage exploration property with three epithermal and porphyry copper-gold targets associated with extensive hydrothermal alteration and zones of stockwork veining. 

The targets represent zones of extensive advanced argillic alteration or “lithocaps”, dominated by intense quartz-alunite alteration within larger areas of quartz-alunite-dickite- pyrophyllite and kaolinite alteration. Limited, peripheral historical drilling (2,730 m) shows propylitic and sericitic alteration at depth at two of the target areas. Clay alteration mineral identification was supported by Terraspec near- infrared mineral analysis. High-temperature alunite (K-alunite) and high-temperature kaolinite (WX-kaolinite) tend to be focused and are generally coincident with the best geochemical anomalies at surface. Hydrothermal alteration mineralogy and zonation patterns, including high-temperature minerals, combined with multi-element geochemical anomalies from extensive historical and more recent sieved surface geochemical sampling surveys, including Mo and Bi, define these target areas. Morro Blanco and Morro Colorado also displays silica flooding and a quartz-veinlet stockwork partially exposed at surface. The stockwork is coincident with the best geochemical and geophysical anomalies. Center line or “B” type veinlets with molybdenite have been observed to the west of the southern targets.

EMX acquired the property from Revelo Resources in 2020 (see EMX Press Release dated March 26, 2020).
