Drillhole 26LHDD073 Hits Extensive Copper-Molybdenum Mineralisation at Target L

Exploration Progress at Target L

FMR Resources Limited, in joint venture with Southern Hemisphere Mining, has completed a significant diamond drillhole (26LHDD073) at Target L within the Southern Porphyry area of the Llahuin Project in Chile. The drillhole, extending to a depth of 1,068 metres, intersected multiple broad zones of mineralised stockwork breccia and porphyry intrusions, marking an important step in delineating the extent of this copper-gold-molybdenum system.

Visible copper and molybdenite sulphides were identified within quartz-sulphide and anhydrite veinlets, alongside disseminated mineralisation typical of porphyry-style hydrothermal systems. These observations suggest the drillhole lies within the footprint of a mineralised intrusive corridor, complementing earlier discoveries at adjacent targets.

Geological and Geophysical Integration

The Target L area was selected based on a combination of alteration mapping, geophysical surveys, and vein orientation vectors, aiming to vector towards the core of the mineralised system. Structural data from multiple drillholes reveal complex vein orientations, interpreted as evidence of multiple fluid pulses and increasing structural complexity closer to the mineralising source.

Downhole geophysical data, including induced polarisation and magnetotelluric surveys, are being integrated with geological and geochemical datasets to refine the three-dimensional model of the porphyry system. This comprehensive approach is critical to prioritising future drill targets and understanding the system’s geometry.

Phase I Drilling Outcomes and Next Steps

Originally planned for approximately 4,000 metres, the Phase I drilling program has surpassed expectations with over 5,000 metres completed, revealing both a shallow epithermal system and an extensive mineralised porphyry system at depth. Managing Director Oliver Kiddie emphasised the importance of forthcoming assay results, which will provide the multi-element geochemical fingerprints necessary to vector more precisely to the mineralised core.

Assay results for all Phase I drillholes are expected in the June 2026 quarter. These results will inform the design of a Phase II drilling campaign focused on testing the mineralised core of the Southern Porphyry system, potentially unlocking significant value for the joint venture partners.

Quality Assurance and Exploration Integrity

The announcement details rigorous sampling, logging, and assay protocols consistent with industry best practice and JORC Code (2012) standards. Independent competent persons have verified the data quality, and extensive geophysical surveys underpin the geological interpretations. This transparency and methodological robustness provide confidence in the exploration results and their potential economic significance.

With Chile’s status as the world’s leading copper producer and the Llahuin Project’s established resource base, these latest findings at Target L reinforce the prospectivity of this joint venture and the potential for a major new porphyry discovery.
