Piedralisa target

Piedralisa target is located 3km to the southeast of the known-resource of the Mocoa porphyry deposits, was a focal point for follow-up exploration, particularly in its northern sector where leach cap outcrops were extensively mapped (refer to news release February 7, 2023). Rock samples from exposed outcrops highlighted elevated concentrations of Cu-Mo-Zn-Pb within sericite-altered dacite and andesite units. These observations correlate with 3D radial symmetric isosurface from intrusive features and demagnetized zones identified in the early 2022 airborne geophysical survey (refer to news release May 3, 2022). Additionally, it has been identified outcrops of dacite-rhyolite porphyry with strong phyllic alteration and some remanent A-type veins as far as 2.5-kilometres east of Mocoa drilled area, highlighting the size and prolonged hydrothermal activity within the Mocoa porphyry system (figure 2 - R00631 and figure 3G).

Estrella target

Previously referred to as target 1 (refer to news release May 3, 2022), the Estrella target is situated approximately 1 km south of the Mocoa porphyry deposit. This area is characterized by a 3D radial symmetric isosurface intrusion, interpreted as a potential porphyry body with elevated Cu-Mo values in rock samples, and strong potassium alteration, as indicated by the radiometric survey. These features are further associated with a 300ppm copper anomaly in soil samples (refer to news release February 7, 2023). Follow-up exploration activities were focused on the eastern section of the target, where leach cap outcrops had been mapped during previous fieldwork (refer to news release February 7, 2023). Detailed rock sampling was conducted across an exposed window of argillized dacite, characterized by extensive quartz and pyrite veining indicative of a leach cap environment similar to the upper parts of the Mocoa porphyry (figure 3A to 3D). Rock sample assay results returned Cu values up to 1,091.1ppm and Mo values up to 158.86ppm (figure 2 and figure 3H and 3I).

Next step

The identification of a targeted 2.5 x 2.0-kilometer zone (figure 2), including the eastern Estrella and northwestern Piedralisa sectors, represents a pivotal step in Libero's exploration efforts. This area has been prioritized for detailed fieldwork, highlighting the company's focus on understanding and expanding the potential of the Mocoa porphyry system. Additionally, Libero geologists are actively exploring anomalies identified in the Neblina target, located north of the drilled Mocoa porphyry area. Their work involves systematically mapping of alteration, veining, and mineralization for rock sampling.

Fieldwork is a cornerstone of Libero's exploration strategy, providing the necessary groundwork to identify new drill targets and refine existing ones. This systematic approach is key for fully evaluating the scale and potential of the Mocoa system, supporting ongoing efforts to expand resources and enhance geological understanding.

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.

Mineralized zones at Mocoa are bulk porphyry-style zones. Rock samples are inherently selective in nature. As such, these results may not be representative of the underlying geological values or the overall mineralization within the sampled area.

Libero Copper operates according to a rigorous Quality Assurance and Quality Control (QA/QC) protocol consistent with industry best practices. For surface samples, 2.5kg of material is taken on each outcrop using chip or channel techniques. Samples are taken by well-trained field helpers supervised by the geologist of the company. Core diameter is a mix of HQ and NQ depending on the depth of the drill hole. Diamond drill core boxes were photographed, sawed, sampled and tagged in maximum 2-metre intervals, stopping in geological boundaries. All samples were bagged, tagged and packaged for shipment by truck from Libero Copper's core logging facilities in Mocoa, Colombia to the Actlabs certified sample preparation facility in Medellin, Colombia. ActLabs is an accredited laboratory independent of the company. Samples are processed in the Medellin facilities where they are analyzed for copper and molybdenum by 4-Acid digest Atomic Absorption (AA) analysis. The sample pulps are air freighted from Medellin to the ActLabs certified laboratory in Guadalajara, Mexico, where they are analyzed for a suite of 57 elements using 4-Acid digest and ICP-MS. In order to monitor the ongoing quality of assay data and the database, Libero Copper has implemented QA/QC protocols which include standard sampling methodologies, the insertion of certified copper and molybdenum standard materials, blanks, duplicates (field, preparation and analysis) randomly inserted into the sampling sequence. QA/QC program also include the ongoing 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 km2 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 totaling 18,321 metres and metallurgical test work B2Gold subsequently executed diamond drill programs in 2008 and 2012.

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' 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.
