West Arunta Drilling and Surveys Reveal Multiple Targets for Tali Resources

Exploration Progress at West Arunta

Tali Resources Ltd (ASX, TR2) has provided a detailed update on its West Arunta Project for the quarter ending 31 December 2025, marking significant strides in its exploration campaign. The company completed an initial reverse circulation (RC) drilling program comprising 12 holes across five prospects; Chilka, Lonar, Maton B, Maton C, and Gibson East; totaling 1,818 metres. These early results, based on composite assays, have helped classify rock types and alteration zones, though some airborne electromagnetic anomalies remain untested, warranting further investigation.

While the Gibson East prospect has been downgraded following drilling, the Chilka and Lonar prospects continue to intrigue with weak to moderate conductive anomalies and anomalous nickel and copper values. The Maton prospects, despite lacking local mineralisation signs, still hold potential for sediment-hosted copper deposits.

New Targets from Geophysical Surveys

Complementing drilling efforts, Tali completed ground-based gravity and passive seismic surveys over a 160km area, significantly increasing data resolution from previous regional surveys. This work identified three new prospects; Lonar East, Khya, and Vanda; each characterised by distinct gravity and magnetic anomalies. For instance, Lonar East features a large gravity high anomaly spanning 2.5km by 1km, while Khya presents a semi-circular magnetic feature with a depth model indicating potential mineralisation zones hundreds of metres below surface.

The Vanda prospect shows elongated magnetic anomalies coinciding with gravity highs, suggesting complex subsurface structures. These findings provide fresh targets for Tali’s upcoming drilling campaigns.

Ongoing Data Review and Upcoming Surveys

In parallel, Tali is conducting a thorough review of all historical and recent geological, geophysical, and geochemical data. This has spotlighted additional prospects; Caspian North, Hutt, and Hutt West; with structural and density features consistent with large-scale mineral systems such as iron oxide copper-gold (IOCG) and carbonatite-associated mineralisation. Notably, the Hutt West prospect remains untested by drilling, representing a compelling opportunity.

The Geological Survey of Western Australia (GSWA) has completed a detailed airborne magnetic and radiometric survey across the entire West Arunta tenure, with data release anticipated in the first quarter of 2026. This dataset is expected to enhance geological interpretations and guide future exploration.

Financial Position and Forward Plans

On the corporate front, Tali Resources maintains a healthy cash balance of approximately $4.2 million as of 31 December 2025, supporting ongoing exploration activities. The company remains on track with its expenditure forecasts outlined in its IPO prospectus. Looking ahead, Tali plans an expansive 2026 field season featuring further gravity surveys, heritage assessments, and a broad drilling program to test multiple prospects.

Additionally, Tali has lodged two new exploration licence applications, signalling its intent to expand its footprint in the region. The company’s leadership, led by Managing Director Rhys Bradley, continues to engage with the market, recently presenting at the Noosa Mining Conference and successfully concluding its Annual General Meeting.
