The primary target of exploration on the Property is an Andean-style porphyry copper - molybdenum deposit. Porphyries typically consist of large masses of hydrothermally altered rock containing quartz veins and stockworks, that include sulfide-bearing veinlets and disseminations, and cover areas up to 10 km2 in size. These altered zones are commonly coincident with shallow intrusives and/or dike swarms and hydrothermal or intrusion breccias. Deposit boundaries are determined by economic factors, which outline ore zones within larger areas of low-grade concentrically zoned mineralization and alteration.

Surface oxidation commonly modifies the distribution of mineralization in weathered environments. Acidic meteoric waters generated by the oxidation of pyrite leach copper from soluble copper minerals and re-deposit it as secondary chalcocite and covellite immediately below the water table in tabular zones of supergene enrichment. The process results in a copper-poor leached cap lying above a relatively thin higher-grade zone of supergene enrichment that in turn overlies a thicker zone of lower-grade primary hypogene mineralization at depth.

Porphyry systems may also exhibit hypogene enrichment. The process of hypogene enrichment may relate to the introduction of late hydrothermal copper-enriched fluids along structurally prepared pathways or the leaching and re-deposition of hypogene copper, or a combination of the two. Such enrichment processes result in elevated hypogene grades.

The large copper-molybdenum porphyries occurring elsewhere in the district such as Río Blanco-Los Bronces, Los Pelambres-El Pachon and El Teniente share common characteristics with Vizcachitas.
