something to think about before the news

The Maricunga Gold-Copper Belt, comprising a NNE trending chain of andesitic to dacitic volcanoes measures approximately 150 kilometres long (north-south) by 30 kilometres wide and hosts a series of epithermal high sulphidation and porphyry-style gold-silver-copper deposits such as La Coipa, Refugio, Aldebaran, La Pepa, Soledad, Pantanillo, Lobo, Escondido, and Marte.

Gold and copper mineralization contained within advanced argillic alteration zones occurs in association with porphyry stockwork systems. These stockwork sytems intrude Eocene-Oligocene andesitic and dacitic volcanic rocks that in turn overlie Permo-Triassic volcanic-plutonic-sedimentary basement rocks. These stockwork systems are localized at intersections of regional N-S and NW trending Andean-style fault structures, that which are common loci for volcanoes and major ore deposits in the region. The Maricunga Belt hosts at least 14 major prospects, including three operating mines and two substantial idle deposits. Combined gold resources in the belt are in the order of more than 43 million ounces of gold.
