Update On Its Drilling Campaign At Luz Maria Copper-Molybdenum Porphyry Project

TORONTO - Western Metallica Resources Corp. reported that drill crews working at the Luz Maria copper-molybdenum drill program have completed the first hole ever drilled at Caña Brava project. Drill hole LM24DD001 was completed by contractor Energold to a depth of 396.1 metres, and drilling of the second hole is currently underway.

Logging of drill holes LM24DD001 and LM24DD002 confirms the presence of a complex Cu-Mo porphyry system, with multiple intrusion phases, and multiple alteration and mineralization events. Alteration and mineralization are observed in both the intrusive rocks and the wall rock siliciclastic sedimentary rocks.

The current drill program is aimed at testing the copper-molybdenum mineralization found over an area of 500 by 300 metres, centered on strongly altered diorite and monzonite outcrops located at the bottom of a dry creek. This geochemical anomaly is coincident with strong anomalies identified during magnetic and Induced Polarization surveys carried out by the Company during 2024. A recent cluster classification analysis of the geophysical surveys has highlighted two targets to be prioritized: class 5 with medium resistivity, high chargeability and high mag-susceptibility, and class 6 with medium/low resistivity, high chargeability, high metal factor and high magnetic susceptibility.

Copper and molybdenum mineralization is closely related to the intensity of quartz veining within strong potassic alteration, represented by secondary biotite, overprinted by a phyllic assemblage of quartz-sericite ± chlorite. The alteration footprint of the system extends over an area of at least 2.7 km by 1.5 km, while the drilling area covers only 5% of the total. Samples of core from hole LM24DD001 have been now entirely submitted to the SGS laboratory in Lima.
