FMR Resources Advances Copper Porphyry Target at Llahuin Chile

FMR Resources Unveils Compelling Copper Porphyry Target in Chile

FMR Resources has successfully refined a large, deep-seated drill target at the Southern Porphyry prospect within its Llahuin Project joint venture in Chile. The company’s recent geophysical remodeling has confirmed multiple signatures consistent with a significant copper porphyry potential, establishing a high-priority target for upcoming drilling operations.

Geophysical Integration Reveals Classic Porphyry Signatures

The reprocessed geophysical data from three complementary methods has defined a coherent target displaying textbook porphyry characteristics. This integration of aeromagnetic (MAG), magnetotelluric (MT), and induced polarization (IP) surveys reveals patterns highly indicative of a substantial copper porphyry system:

• • Magnetic body located on the southern side of the target area, likely representing magnetite-bearing intrusive phases

• • MT resistivity anomaly positioned immediately north of the magnetic body, coincident with IP resistivity lows

• • Strong IP chargeability anomalies flanking the magnetic body to the east and west

This spatial arrangement mirrors the classic porphyry model, where a central magnetite-rich core is surrounded by sulphide-rich zones and broader alteration halos.

“The reprocessed geophysics gives us a much sharper and more confident set of targets at Southern Porphyry. The alignment between the magnetics, MT, and IP datasets, combined with the alteration and geochemical signatures we have mapped at surface and in historic drillholes, is compelling, and exactly what we want to see to guide Phase I drill targeting. This is a genuine high-priority porphyry target which we are on track to test in early Q4 2025.” – Oliver Kiddie, Managing Director, FMR Resources

Surface Geology Supports Deep Target Potential

The geophysical modeling at FMR Resources’ copper porphyry target in Chile aligns with surface geological observations. Recent field mapping at Southern Porphyry identified key indicators of a porphyry system’s upper levels:

• • Argillic alteration (clay mineral formation)

• • Silicification (introduction of silica into rock)

• • Epithermal quartz veining

• • Secondary copper mineral assemblages

Re-logging of historic drillholes further confirmed these features at depth, with intervals showing hydrothermal alteration, silicification, and disseminated chalcopyrite-pyrite mineralization. These observations suggest a telescoped system with potential for a significant copper porphyry at depth.

Understanding Magnetotelluric Surveys in Porphyry Exploration

Magnetotelluric (MT) surveys measure natural variations in the Earth’s electromagnetic field to map resistivity structures at depth. In porphyry exploration, MT resistivity surveys are particularly valuable for identifying deep conductive zones that may represent mineralized systems beneath cover or at depths beyond the reach of other methods.

The high-amplitude MT anomaly identified at FMR Resources’ copper porphyry target in Chile is significant because:

1. 1. It indicates a large, strong conductive source at depth

1. 1. It aligns spatially with other geophysical signatures typical of porphyry systems

1. 1. It helps define the geometry and depth of the potential mineralized zone

1. 1. It complements shallower IP data to build a comprehensive target model

The integration of MT with other geophysical methods provides a robust targeting framework that significantly enhances drilling success rates. This advanced 3D modeling approach has been crucial in defining the Southern Porphyry target.

Strategic Position Within Mineralized Corridor

The Southern Porphyry target is situated within a 6 km-long mineralized corridor at Llahuin that hosts multiple copper-gold-molybdenum porphyry centres. This regional setting enhances the prospectivity of the target, placing it in a proven metallogenic belt with established mineralization.

This table summarizes how the different geophysical methods contribute to the compelling case for FMR Resources’ copper porphyry target in Chile.

Drilling Timeline and Next Steps

FMR Resources has outlined a clear path to testing this compelling target:

• • Finalise drill contractor engagement in the coming weeks

• • Complete final drill program design incorporating refined geophysical models

• • Complete statutory drilling approvals and site preparation

• • Commence Phase I drilling at Southern Porphyry in early Q4 2025

This methodical approach demonstrates the company’s commitment to rigorous exploration practices and increases the probability of drilling success at this promising copper porphyry target.
