Gravity and Magnetic Anomalies Define Two Large Prospects at West Arunta
Tali Resources has identified significant new geophysical anomalies at its West Arunta Project, highlighting two promising prospects and securing a $220,000 grant to advance drilling plans in 2026.
- Discovery of large-scale gravity and magnetic anomalies at Khya and Vanda prospects
- Passive seismic data reveals shallower bedrock depths than previously thought
- Exploration Incentive Scheme grant of $220,000 awarded for drill testing
- Prospects located adjacent to major Lake Mackay Fault, indicating strong mineralisation potential
- Planning underway for expanded 2026 exploration including drilling and further surveys
Significant New Targets in Untapped Territory
Tali Resources Ltd (ASX – TR2) has announced a major step forward in its exploration efforts at the West Arunta Project in Western Australia. Recent ground-based gravity and passive seismic surveys have revealed two substantial geophysical anomalies, the Khya and Vanda prospects, in an area previously unexplored at this scale. These anomalies coincide with strong magnetic highs and lie adjacent to the prominent Lake Mackay Fault, a regional structure considered a potential conduit for mineralising fluids.
Geophysical Insights and Exploration Implications
The Khya prospect features a semi-circular magnetic high spanning 3.5 kilometers, paired with a discrete gravity anomaly of up to +1.0mGal. Meanwhile, the Vanda prospect hosts multiple elongated gravity anomalies up to +0.8mGal, partially overlapping magnetic highs reaching 450nT. Importantly, passive seismic data indicates that the bedrock beneath these targets is significantly shallower than earlier models suggested, ranging from 120 to 370 meters deep, which could reduce drilling complexity and costs.
Financial Backing and Next Steps
Recognising the potential of these discoveries, the Western Australian Department of Mines, Petroleum and Exploration has awarded Tali a $220,000 Exploration Incentive Scheme grant to co-fund upcoming drill testing. This financial support underscores the prospects’ promise and enables Tali to accelerate its planned 2026 field campaign. The company is preparing to drill both Khya and Vanda, alongside conducting infill and extension gravity surveys to refine target definitions.
Strategic Positioning in a Mineral-Rich Region
Located approximately 30 kilometers west of WA1 Resources’ recent P2 carbonatite discovery, these prospects lie within a geologically prospective corridor for iron oxide copper gold (IOCG) and carbonatite-associated mineralisation. The West Arunta Project’s basement geology remains poorly constrained due to limited outcrop and historical exploration, making these geophysical findings particularly valuable as a guide for future work.
Outlook for Tali Resources
With a robust pipeline of new targets emerging from systematic geophysical surveys, Tali Resources is positioning itself to unlock significant value in one of Australia’s most exciting emerging mineral provinces. The combination of compelling geophysical signatures, strategic grant funding, and a clear exploration roadmap sets the stage for potentially transformative drilling results in the coming year.
Bottom Line?
Tali’s 2026 drilling campaign at Khya and Vanda could redefine the West Arunta’s mineral potential and reshape investor expectations.
Questions in the middle?
- What will the initial drill results reveal about the mineralisation style and grade at Khya and Vanda?
- How might the shallower bedrock depths impact the cost and speed of exploration development?
- Could further geophysical surveys uncover additional targets within the West Arunta tenure?
