Geology
The Mocoa deposit is located in the Jurassic belt in the Andean cordillera (Central Cordillera of Colombia), a 30km wide tectonic belt underlain by volcano-sedimentary, sedimentary and intrusive rocks that range in age from Triassic-Jurassic to Quaternary, and by remnants of Paleozoic metasediments and metamorphic rocks of Precambrian age. This Jurassic belt hosts several other porphyry-copper deposits, such as Mirador,, San Carlos-Panantza and Solaris' flagship Warintza all located in Ecuador.
Note: Mirador, San-Carlos-Panantza and Warintza are independent of Libero Copper and are no guarantee of the future performance of Libero projects and no inference can be made of mineral resources or reserves from adjacent deposits
Copper-molybdenum mineralization is associated with a dacite porphyry intrusion and breccia-related of Early to Middle Jurassic age emplaced into andesitic and dacitic volcanic rocks grouped into the Saldaña Formation. The Mocoa porphyry system exhibits a classical zonal pattern of hydrothermal alteration and mineralization, with a deeper central core of potassic alteration (Kspar) overlain by sericitization and surrounded by propylitization. Mineralization consists of disseminated chalcopyrite, molybdenite and minor contents of bornite and chalcocite associated with multiphase veins, stockworks and hydrothermal breccias. The Mocoa deposit is roughly cylindrical, with a 600m diameter and thicknesses that range from 250m to 350m. High-grade copper-molybdenum mineralization continues to depths in excess of 1,000m and open in all directions
