VANCOUVER, BC, May 3, 2022 /CNW/ - Libero Copper & Gold Corporation (TSXV: LBC) (OTCQB: LBCMF) (DE: 29H) is pleased to announce the company has completed the interpretation of the detailed airborne magnetic and radiometric survey data, flown at the end of 2021, and the interpretation of all surface rock sample geochemical data on the project to date, resulting in the identification of 9 new porphyry targets in the immediate area at the Mocoa porphyry copper deposit located in Putumayo, Colombia.
"In addition to the exceptional initial results from the maiden drill program, Libero Copper continues to make significant advancements towards demonstrating the potential to increase the endowment of mineralization associated with the Mocoa deposit and the surrounding area. The apparent clustered porphyry system recently identified as a result of the airborne magnetic and radiometric survey that was flown at the end of 2021, has also identified new opportunities around and beyond the limits of the Mocoa deposit," comments Ian Harris, President & CEO. "The new targets identified will be systematically evaluated and receive the necessary follow-up work to be included in our ongoing field work and upcoming drill planning. This is another important advancement for Libero Copper and the Mocoa project and we look forward to continuing the evaluation and applying this systematic approach to the entire Mocoa land position."
In late 2021, MPX Geophysics, completed magnetic, radiometric and LiDAR surveys over the Mocoa project area covering 87 km2. Daniel Core, PhD., of Fathom Geophysics, Westerville, Ohio, was contracted by Libero Copper to process and interpret the geophysical data. All available geotechnical data was provided to Fathom Geophysics to assist with the interpretation of the airborne survey data and Libero Copper processed the historic surface rock sample geochemical data to assist with the interpretation.
Processing and interpretation of the airborne geophysical data was performed by Fathom Geophysics and the main products produced include: geological interpretation with de-magnetized zone, structural interpretation, Analytic Signal magnetic (AS) map, K alteration index map, and magnetic inversion vector model with 3D radial symmetric isosurfaces (porphyry finger model).
The main outcomes and conclusion from the geophysical interpretation are as follows:
The targets identified are summarized as follows (refer to figures 1 to 9 below in relation to target descriptions):
Libero Copper is currently advancing the systematic exploration on the Mocoa project and will be initiating a soil sampling program, prospecting and mapping programs across the entire district scale property.
The Mocoa deposit is located in the department of Putumayo, 10 kilometres from the town of Mocoa. Libero Copper's district scale holdings cover over 1,000 km2 encompassing most of the Jurassic porphyry belt in southern Colombia. Mocoa was discovered in 1973 when the United Nations and the Colombian government conducted a regional stream sediment geochemical survey. Between 1978 and 1983, an exploration program was carried out that consisted of geological mapping, surface sampling, ground geophysics (IP, magnetics), 31 diamond drill holes totaling 18,321 metres and metallurgical test work cumulating in a positive pre-feasibility study (the pre-feasibility study is historical in nature only and should not be relied upon as it is not NI 43-101 compliant). B2Gold subsequently executed diamond drill programs in 2008 and 2012.
A pit constrained inferred resource at Mocoa contains 636 million tonnes of 0.45% copper equivalent (0.33% Cu and 0.036% Mo)1 generated using $3/lb Cu and $10/lb Mo, containing 4.6 billion pounds of copper and 511 million pounds of molybdenum. The Mocoa deposit appears to be open in both directions along strike and at depth. Current work on the property has identified additional porphyry targets including the possible expansion of known mineralization which will receive additional follow-up drilling in 2022.
The Mocoa deposit is situated in the Eastern Cordillera of Colombia, a 30-kilometre-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 in Ecuador, such as Mirador (438 million tonnes measured and indicated at 0.61% Cu and 235 million tonnes inferred at 0.52% Cu)3, San Carlos (600 million tonnes inferred at 0.59% Cu)3, Panantza (463 million tonnes inferred at 0.66% Cu)4 and Solaris' Waritza, located in Ecuador.
Copper-molybdenum mineralization is associated with dacite porphyry intrusions of the Middle Jurassic age that are 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 and chalcocite associated with multiphase veins, stockwork and hydrothermal breccias. The Mocoa deposit is roughly cylindrical, with a 600 metre diameter. High-grade copper-molybdenum mineralization continues to depths in excess of 1,000 metres.
