| ABSTRACT: | This technical report provides a mineral resource estimate for Libero Copper Corporation’s Mocoa Copper-Molybdenum Project. The report was written by Michel Rowland Brepsant, FAusIMM, Robert Sim, P.Geo., and Bruce Davis, FAusIMM, all independent “qualified persons” (QPs) as defined by Canadian Securities Administrators National Instrument 43- 101 Standards of Disclosure for Mineral Projects (NI 43-101) and as described in Section 28 (Date and Signature Pages) of this report. This technical report was initially prepared in October 2016 based on the expected acquisition of the Mocoa Property by Libero Copper. Resource estimation was new work conducted by Libero Copper using data supplied by B2. The transaction did not occur in 2016 and the technical report was never filed. There has been no additional work of any kind completed on the Mocoa Property since the initial preparation of this report and, as a result, it remains current with an effective date of October 6, 2016. The Mocoa deposit is situated in the Eastern Cordillera of Colombia, a 30 km 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 belt hosts several other porphyry-copper deposits, such as Mirador, San Carlos, and Panantza, located in southeastern Ecuador (von Guttenberg, 2008). The geology of the Mocoa deposit has been described by Sillitoe et al. (1984). Coppermolybdenum mineralization is associated with a dacite porphyry intrusion of Middle Jurassic age emplaced into andesitic and dacitic volcanics. The Mocoa porphyry system exhibits a classical zonal pattern of hydrothermal alteration and mineralization, with a deeper central core of potassic alteration overlain by sericitization and surrounded by propylitization. Mineralization consists of disseminated chalcopyrite, molybdenite and local bornite associated with multiphase veins, stockworks and hydrothermal breccias. Patchy surface oxidation extends to a depth of 150 m and overlaps a 70 m to 220 m thick barren quartzsericite-pyrite lithocap that overlies primary copper-molybdenum mineralization. The deposit contains no significant supergene copper mineralization. | |
