Buxton Resources Ltd (ASX: BUX) high-priority copper-gold targets advanced at Lateron

Buxton Resources has refined three high-priority copper-gold drill targets at its 100 percent owned Lateron Project, located on the western margin of the Tanami Province approximately 150 kilometres south of Halls Creek.

The company has integrated recent ground gravity, airborne magnetic data and passive seismic surveying to form a coherent geological model that defines discrete intrusive targets beneath shallow cover.

Highlights

• Three drill-ready intrusive-related copper-gold targets defined.

• Petrographic analysis confirms hornblende-bearing intrusive rocks containing pyrite and chalcopyrite.

• Geophysical inversion modelling has refined target geometry at depths starting from 77.5 metres.

• Heritage agreement negotiations nearing completion, enabling ground access preparations ahead of a planned 2026 drilling program.

The Lateron Project covers magnetic anomalies that have been only lightly explored since historical uranium drilling in the early 1980s.

A single diamond hole from that period intersected basement intrusive rocks from 77.5 metres depth, although no geochemical assay data were recorded.

The new interpretation, informed by modern geophysical data and supported by petrography, indicates the presence of sulphide-bearing hornblende quartz diorite with accessory magnetite and chalcopyrite.

The presence of these minerals, particularly where associated with hydrated and oxidised magmatic environments, is widely recognised in intrusive-related copper-gold systems.

Buxton Resources reports that the gravity and magnetic datasets highlight four distinct magnetic features surrounding a central, fault-bounded dense block.

The survey work has reduced ambiguity around the depth to basement and the extent of structural control.

The passive seismic data suggests variations in cover thickness correspond to long-lived structural trends, providing context for fluid migration pathways and potential mineral system development.

A key interpretive statement from the release notes that these rocks tend to be related to, and occur nearby, magmatic or hydrothermal sulphide deposits.

This observation underscores the geological rationale for renewed drilling and highlights the importance of mineralogical evidence recovered from the historic core fragments.

The company is in the process of finalising a Heritage Protection and Land Access Agreement with the Tjurabalan Native Title Lands Aboriginal Corporation.

Once completed, heritage surveys can be undertaken ahead of drilling activity planned for 2026.

No impediments to tenure have been identified, and the project area does not contain any registered Aboriginal heritage sites, although part of the tenement overlaps the Paruku Indigenous Protected Area and access will be managed accordingly.

The exploration strategy at Lateron is focused on testing concealed intrusive features that have not previously been assessed for copper or gold content.

While the historical drilling provides only limited geological context, the combination of mineralogical evidence, coherent geophysical signatures and improved structural understanding gives the company a clear framework for initial drill testing.

Buxton’s next steps involve completing access agreements, conducting heritage surveys and finalising drill planning.

The outcome of the initial drilling will determine whether the intrusive system at Lateron hosts economically meaningful sulphide mineralisation.

In the broader context of renewed interest in intrusion-related copper-gold systems across northern Australia, the project provides a technically grounded and geologically coherent exploration proposition, with the forthcoming drill program expected to provide the first definitive test of the system’s potential.
