Argent Minerals Extends Kempfield Silver Mineralisation by 100m Depth

Depth Extension Confirms Bulk-Tonnage Potential

Argent Minerals Limited (ASX:ARD) has unveiled a significant breakthrough at its 100%-owned Kempfield Polymetallic Project in New South Wales, with diamond drillhole AKDD213 intersecting a continuous 159.1-metre zone averaging 80.6 g/t silver equivalent (AgEq) from just 17.9 metres downhole. This result extends the known vertical mineralisation by approximately 100 metres beyond previous limits, which had been constrained to around 90 metres depth, reinforcing Kempfield’s status as a large-scale polymetallic system with compelling bulk-tonnage potential.

The intercept includes multiple higher-grade shoots, such as an 18.2-metre zone grading 145.3 g/t AgEq from 194.4 metres, offering clear vectors for further depth extensions. The broad intercept grade aligns closely with the existing Lode 100 Mineral Resource Estimate (MRE) average of 81.1 g/t AgEq, providing strong validation for the current resource model and supporting ongoing resource expansion efforts.

Robust Polymetallic System with High-Grade Cores

The mineralisation is hosted within a barite-rich greywacke unit of the Silurian volcanogenic massive sulphide (VMS) sequence, featuring disseminated pyrite with stringers of sphalerite and galena. AKDD213’s results reveal a vertically continuous, west-dipping ore-bearing zone with internal high-grade silver and base metal shoots, including intervals exceeding 80 to 129.3 g/t AgEq and base metal enrichment up to 3.54% combined lead and zinc.

A central core of enhanced silver mineralisation was identified over 105.6 metres at 57.5 g/t AgEq, including a 22.7-metre sub-interval grading 85.7 g/t silver and 1.84% lead. This confirms the persistence of high-grade shoots within a broader mineralised envelope and highlights the potential for large-scale bulk mining scenarios. The mineralised zone remains open both down-plunge and along strike, inviting further step-out drilling to expand the resource footprint.

Geological Continuity Across Lode 100 and Lode 200

Cross-sectional analysis demonstrates strong vertical and lateral continuity of mineralisation across Kempfield’s Lode 100 and Lode 200 zones. While Lode 100 shows a more consistent thickness and grade profile with long runs of moderate-to-high-grade silver mineralisation, Lode 200 presents a larger, bulbous geometry near surface transitioning into a deeper feeder zone with multiple wide intercepts and high-grade cores.

The interpreted mineralised corridor adjacent to a fault contact suggests structural controls localise higher-grade shoots. The presence of multiple open zones below the current 600RL level, where mineralisation is sparsely tested, underscores the opportunity for resource growth. These findings build on previous drilling successes such as the 133m intercept reported in April, which also extended mineralisation depth and confirmed polymetallic continuity 133m intercept averaging 72.4 g/t Ag Eq.

Implications for Project Development and Exploration

The Kempfield deposit remains one of Australia’s most significant undeveloped silver resources, with a July 2024 MRE reporting 63.7 million tonnes at 69.75 g/t silver equivalent for 142.8 million ounces AgEq, including substantial gold, lead, and zinc credits. The new drilling results reinforce the project's potential to support various development pathways, including near-surface starter operations and large-scale bulk mining.

Argent Minerals continues to advance metallurgical testwork and exploration programs across Kempfield and its nearby assets such as Trunkey Creek and Pine Ridge, which offer additional gold upside. The company is navigating a leadership transition with Managing Director Pedro Kastellorizos set to depart in June, yet exploration and project development remain on track leadership transition underway.
