LIBERO COPPER ANNOUNCES UPDATE TO COLOMBIA'S CADASTRAL RECORDS ENHANCING MOCOA PROJECT POTENTIAL
Libero Copper & Gold Corp. has made significant advancement in the development of its flagship Mocoa project. Following dedicated efforts and close collaboration with Colombian authorities to implement the Consejo de Estado Resolution dated Aug. 4, 2022 (clarified on Sept. 29, 2022, filing No. 25000234100020130245901) -- which mandates the alignment of environmental and mining records -- the official mining cadastral system, ANNA Mineria, has updated its records concerning the Mocoa project area.
The regional forest reserve was originally established on Nov. 21, 1984, intended to protect and compensate for the planned construction of an 11-megawatt hydroelectric plant that was never built. Due to ambiguous co-ordinates at the time of its creation, the reserve's boundaries were inaccurately reflected in official records, leading to an unintended overlap with the Mocoa project's mineral resource area. This pivotal update addresses a previous note in the National Instrument 43-101 technical report titled "Technical Report on the Mocoa Copper-Molybdenum Project, Colombia," dated Jan. 17, 2022, prepared by Michael Rowland Brepsant, FAusIMM, Robert Sim, PGeo, and Bruce Davis, FAusIMM, with an effective date of Nov. 1, 2021. The updated cadastral records now clarify that the regional forest reserve no longer overlaps with the Mocoa project's existing mineral resource area.
"This update represents a significant step forward in our collaborative work with Colombian authorities to responsibly develop the Mocoa project. The clarified boundaries allow us to plan with greater certainty, demonstrating the effectiveness of our co-operative approach in aligning mining and environmental regulations," commented Ian Harris, president and chief executive officer of Libero Copper. "We look forward to completing the next steps and are more confident than ever in the immense potential of the Mocoa project and remain committed to advancing it responsibly for the benefit of all stakeholders."
This update marks an important milestone in the continuing collaboration among the Agencia Nacional de Mineria (ANM), the Ministry of Mines and Energy, and the Ministry of Environment, as they work to align environmental data with mining title information and implement the full scope of the Consejo de Estado decision. This achievement reduces uncertainty by clarifying boundaries, enabling the company to proceed with enhanced confidence and efficiency.
The collective efforts have set the stage for further advancements that will support the Mocoa project's compliance with Colombia's mining regulations. Ultimately, this collaborative success will allow Libero Copper to finalize its updated Programa Unico de Exploracion y Explotacion (PUEE), ensuring a robust and responsible exploration strategy that aligns with regulatory best practices and Colombia's sustainable development goals.
Qualified person and technical notes
Edwin Naranjo Sierra, exploration manager of Libero Copper, is the designated qualified person within the meaning of National Instrument 43-101 and has reviewed and verified the technical information in this news release. Mr. Naranjo holds a MSc in earth sciences and is a fellow of the Australasian Institute of Mining and Metallurgy (FAusIMM) and the Society of Economic Geologist.
Libero Copper operates according to a rigorous quality assurance and quality control (QA/QC) protocol consistent with industry best practices. Primary sample collection involves secure transport from Libero Copper's core logging facilities in Mocoa, Colombia, to the ActLabs certified sample preparation facility in Medellin, Colombia. Samples are processed in the Medellin facilities where they are analyzed for copper and molybdenum by four-acid digest AA (atomic absorption) analysis. The sample pulps are air freighted from Medellin to the ActLabs certified laboratory in Guadalajara, Mexico, where they are analyzed using four-acid digest ICP (inductively coupled plasma) multielement analysis. In order to monitor the continuing quality of assay data and the database, Libero Copper has implemented QA/QC protocols which include standard sampling methodologies, the insertion of certified standard materials, blanks and field duplicates, and continuing monitoring of data entry, QA/QC reporting and data validation. No material QA/QC issues have been identified with respect to sample collection, security and assaying.
About the Mocoa porphyry copper-molybdenum deposit
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 square kilometres through titles and applications, 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 totalling 18,321 metres and metallurgical test work. B2Gold subsequently executed diamond drill programs in 2008 and 2012. Libero Copper drilled Mocoa in 2022 and intercepted notable results of 0.58 per cent copper equivalent (CuEq) (0.42 per cent (Cu) and 0.047 per cent molybdenum (Mo)) over 1,228.5 metres, including a higher-grade interval of 840.3 metres at 0.72 per cent CuEq (0.52 per cent Cu and 0.062 per cent Mo) (see news release April 26, 2022).
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. The Mocoa deposit is situated in the Central 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, San Carlos, Panantza and Solaris's Warintza. 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.
