Litchfield Minerals Limited (ASX:LMS)

Litchfield Minerals Limited announced that September 2026 reconnaissance at its Harts Range Project in the Northern Territory strengthened exploration targets at Sybil and Illogwa Creek, with visually identified copper-bearing minerals including chalcopyrite and malachite at the Sybil P4 target and sulphide-bearing mafic rocks near Illogwa anomaly 26 supporting follow-up ground electromagnetic surveys. At Sybil, historical VTEM data reviewed and remodelled by Mitre Geophysics outlined several conductors, with P4 interpreted at about 400m by 200m, and fieldwork found disseminated sulphides in garnet-bearing amphibolite plus nearby malachite staining along a faulted contact, increasing confidence in the area as a priority copper target, though mineralisation extent, grade and continuity remain unconfirmed pending assays. At Illogwa Creek, mapped sulphide-bearing mafic rocks, alteration, moderate to strong magnetism, an untested EM conductor and an interpreted deep structural corridor linked to the Illogwa Creek Shear Zone were considered consistent with testing Litchfield’s orthomagmatic copper-nickel model, while recognising that mantle connectivity and sulphide origin are still interpretive. The company submitted 19 selective rock chip samples, plus a standard and a blank, for laboratory analysis and plans to integrate those results with mapping and refined EM modelling to define potential drill targets, with all current mineral identifications and abundance estimates described as preliminary visual observations only.
