Chamana Project

According to the graph on the right (Halley et al., 2015), the Chamana prospect exhibits rocks with concentrations of Tl >1.5 ppm, suggesting its location within a geochemical zone characterized by extensive advanced argillic alteration.

These anomalies are associated with volcanic centers defined by ring structural features.

Additionally, by integrating remote sensing data, it is likely that these areas are covered by phyllic alteration.

Given the extensive alteration on a kilometer scale and the evidence supporting it, the study area is interpreted as a large lithospheric layer formed from multiple volcanic centers, indicating potential for world-class alteration.
