Argent Minerals Uncovers Massive High-Grade Silver Zones at Kempfield

Exceptional Drilling Results at Kempfield

Argent Minerals Limited (ASX, ARD) has announced a breakthrough in its exploration efforts at the Kempfield Silver-Polymetallic Project in New South Wales. The company’s latest diamond drillhole, AKDD208, has intersected an impressive 196.4 metres of mineralisation spread over three distinct zones, featuring exceptionally high-grade silver and base metals. Notably, intervals of 27 metres grading 226.2 grams per tonne (g/t) silver equivalent and 42.6 metres at 102.02 g/t silver equivalent highlight the strength and continuity of the deposit.

These results reinforce Kempfield’s standing as one of Australia’s premier undeveloped silver-polymetallic projects. The mineralisation begins near surface at just 20 metres depth, which could favour early-stage mining opportunities. The presence of thick, robust silver zones with associated lead, zinc, and minor gold further enhances the project’s economic potential.

Discovery of a New Mineralised Zone

Beyond confirming known mineralised lenses, AKDD208 also revealed a previously unknown zone at 283 metres depth, underscoring the underexplored nature of the Kempfield volcanogenic massive sulphide (VMS) system. This new zone returned 8.8 metres at 49.54 g/t silver equivalent, adding to the resource upside and exploration excitement.

Following these encouraging results, Argent has secured regulatory approval from New South Wales authorities to proceed with further diamond drilling north of AKDD208. This next phase aims to test the northern extensions of the mineralisation, with drilling expected to commence imminently.

Advancing Metallurgical Testwork and Development

Samples from both AKDD208 and the recently completed AKDD209 drillholes have been sent to Auralia Metallurgy for comprehensive testwork. This includes heap leach and carbon-in-leach (CIL)/flotation processing trials, critical steps in defining the optimal extraction methods for the polymetallic ore.

Argent’s Managing Director, Pedro Kastellorizos, emphasised the significance of these results, noting that the extensive high-grade intersections materially enhance Kempfield’s development prospects. He highlighted the potential for selective mining of near-surface zones and the opportunity to expand the mineral resource base, which will underpin future feasibility and development studies.

Context Within Argent’s Broader Portfolio

Kempfield remains Argent Minerals’ flagship project, hosting Australia’s second-largest undeveloped silver deposit, with a recent resource estimate of 63.7 million tonnes at 69.75 g/t silver equivalent, containing approximately 142.8 million ounces silver equivalent. The project’s location in the prolific Lachlan Fold Belt near Orange places it in a renowned mining district alongside major operations such as Newcrest’s Cadia and Northparkes mines.

Argent’s broader portfolio includes gold projects at Trunkey Creek, Mt Dudley, and Pine Ridge, which offer additional upside and the potential for a scalable multi-deposit mining operation in the region.
