San Lázaro is a high-potential porphyry copper-gold-(molybdenum) project covering approximately 1,600 hectares in Chile’s Tarapacá Region, located just 15 km south of the world-class Collahuasi mining district. Situated at 4,000 metres elevation with year-round access (about a four-hour drive from Calama), the property targets a large, undrilled Tertiary porphyry system under shallow cover within a multi-kilometre chargeability anomaly. Previous work by majors including Rio Tinto confirmed the geological setting; Rosa Ventures’ reinterpretation highlights a 2 × 1 km drill-ready target with multi-hundred-million-tonne potential analogous to the major deposits of the Collahuasi district.
