FMR Resources Confirms Broad Porphyry Mineralisation at Llahuin Ahead of Phase II Drilling

Broad Porphyry Footprint Confirmed by Final Assays

FMR Resources Limited (ASX:FMR) has received the final assay results from diamond drillhole 26LHDD073 at the Southern Porphyry target within the Llahuin Project Joint Venture in Chile, operated alongside Southern Hemisphere Mining (ASX:SUH). The assays confirm a broad copper-gold-molybdenum mineralised porphyry system, with significant intervals including 24 metres at 0.14% copper equivalent (CuEq) from 156 metres and 4 metres at 0.78% CuEq from 582 metres.

These results validate earlier geological observations of multiple porphyry intrusive phases, stockwork breccias, and pervasive hydrothermal alteration intersected by the drillhole. Visible chalcopyrite and molybdenite sulphides throughout the core reinforce the interpretation of a mineralised intrusive footprint rather than the higher-grade core itself.

Integration of Multi-Disciplinary Data to Refine Targets

FMR is actively integrating assay data with petrographic studies, multi-element geochemistry, and geophysical models including Induced Polarisation and Magnetotelluric surveys. This multi-disciplinary approach aims to refine vectors towards the elusive higher-temperature copper-molybdenum core of the Southern Porphyry system.

Downhole geophysical data from recent drillholes are being compared against surface geophysical models to understand sulphide mineralisation and alteration patterns. Petrophysical testwork on selected samples is underway to improve geophysical inversion models, enhancing the precision of future drill targeting.

Geological Context and Next Steps

The Southern Porphyry target lies within a six-kilometre-long mineralised corridor hosting multiple copper-gold-molybdenum porphyry centres. Surface mapping has identified argillic alteration, silicification, and epithermal quartz veining typical of the upper levels of a telescoped porphyry system.

Drillhole 26LHDD073 was designed to test structural and geochemical vectors interpreted from earlier holes, confirming increasing vein complexity closer to the porphyry fluid source. The company emphasises that existing drilling has so far intersected the margins of an extensive porphyry intrusive corridor, with the higher-grade core yet to be located.

FMR plans to finalise Phase II drill targeting based on the integrated geological and geophysical interpretation, with drilling expected in the fourth quarter of 2026. This next phase aims to test the interpreted core and potentially unlock higher-grade mineralisation.

Resource Background and Metallurgical Insights

The Llahuin Project hosts a substantial JORC-compliant resource of 218 million tonnes at 0.38% CuEq, combining measured, indicated, and inferred categories. Metallurgical testwork indicates copper recoveries between 84% and 91%, gold recoveries around 50%, and molybdenum recoveries varying widely but averaging about 40%. These preliminary figures suggest good flotation characteristics with low deleterious elements in concentrates.

While the CuEq calculations assume 100% in situ recovery for comparative purposes, the company is clear that economic viability depends on ongoing metallurgical optimisation and further drilling results.

Managing Director’s Perspective

Managing Director Oliver Kiddie noted, "The assays from Target L validate our geological model, confirming broad mineralisation associated with porphyry intrusive phases and stockwork breccia. Importantly, the geochemical data support our view that we have intersected the margins rather than the core. Our ongoing integration of diverse datasets is sharpening our vectors for the upcoming Phase II drilling campaign.”

With the Southern Porphyry system’s core still untested, the upcoming drill program represents a crucial step in unlocking the project’s full potential.
