The San Valentino royalty asset covers a 1,100 hectare land position close to the Central Chilean Miocene porphyry copper belt. The property is located 145 km north of Santiago and 45 km south-southwest of the giant Los Pelambres copper mine. San Valentino is an early-stage exploration property prospective for porphyry copper mineralization. The main target at San Valentino is a zone of advanced argillic with overall dimensions of approximately 3.5 km by 1.5 km that parallels major fault structures and is coincident with a significant Mo-Pb-Au-As soil anomaly above dacitic and dioritic host rocks. Surface outcrops are intensely leached. These characteristics are consistent with the advanced argillic or base of lithocap environment found above a porphyry copper system. Historical drilling at San Valentino targeted auriferous silica ledges at topographically higher elevations, 3 km to the north of the principal porphyry copper target, which has never been drill tested. Potential exists for (possibly) immature secondary copper enrichment, but the main exploration target is hypogene porphyry copper mineralization beneath the geochemically anomalous lithocap. The current property owner is Atacama Copper Exploration (“Atacama”), a private Canadian company, who agreed to spend U.S. $250,000 in exploration activities and drill test the property by Q4 2021. EMX acquired the 1% NSR royalty asset from Revelo Resources in 2020 (see EMX Press Release dated March 26, 2020).
