Tali Resources Drills Maiden 700m Diamond Hole Targeting Copper-Gold in West Arunta
Key Takeaways
- Tali Resources (ASX: TR2) has commenced its maiden diamond drill hole, pKDD001, at the Khya prospect within the West Arunta Project, targeting a coincident gravity and magnetic anomaly at approximately 700m depth.
- The program is backed by a $270,000 Exploration Incentive Scheme co-funding grant from the Geological Survey of Western Australia, an independent signal of the target's scientific merit.
- The Khya target sits within the Lake Mackay Fault Zone, where Tali holds approximately 90km of untested strike — meaning this first hole tests a fraction of the available corridor.
- Tali moved the Khya target from concept to drill-ready in under 12 months, a meaningful execution benchmark for a junior explorer in an underexplored region.
- No assay data has been released yet — results from pKDD001 will be the primary near-term catalyst, with the hole forming part of a broader 2026 multi-prospect campaign across the West Arunta Project.
Tali Resources drills maiden diamond hole at Khya, West Arunta
Tali Resources Ltd (ASX: TR2) has commenced diamond drilling at the Khya prospect within its West Arunta Project in Western Australia. This is the company’s maiden diamond drill hole, targeting a large-scale copper-gold and critical minerals system within the Lake Mackay Fault Zone.
The program is backed by a $270,000 Exploration Incentive Scheme (EIS) co-funding grant from the Geological Survey of Western Australia (GSWA). The planned hole is designed to reach approximately 700m depth, where overlapping gravity and magnetic anomalies converge on a compelling concealed target.

What the drill hole is designed to test
The diamond drill hole, designated pKDD001, is designed to test the priority south-west Khya gravity high anomaly. The technical design progresses from surface cover through to a deeply modelled gravity feature, before intersecting a magnetic target zone projected at end of hole.
Key technical parameters:
- Priority target: South-west Khya gravity high anomaly
- Design: Passes through the base of cover and into the modelled gravity anomaly
- End-of-hole target: Overlapping magnetic target zone projected at approximately 700m depth
- Anomaly type: Coincident gravity and magnetic — a multi-geophysical target
The coincident nature of the gravity and magnetic anomalies is the central technical hook. When two independent geophysical signals overlap at depth, it strengthens the geological case that a material body exists at that location.
Rhys Bradley, Managing Director, Tali Resources
“It is great to see Tali’s maiden diamond drill hole now underway at Khya, a compelling concealed copper-gold and critical minerals target within the underexplored Lake Mackay Fault Zone in the West Arunta. … Progressing the target from concept to drilling within 12 months is a significant milestone for the Company and demonstrates the team’s ability to rapidly generate, refine and advance high-quality exploration opportunities.”
Understanding why the Lake Mackay Fault Zone matters
Fault zones are among the most important structural features in mineral exploration. They act as conduits and traps for mineralising fluids, which are the hot, metal-rich solutions that move through the Earth’s crust and deposit copper, gold, and other metals as they cool and react with surrounding rock. The Lake Mackay Fault Zone, running through Tali’s West Arunta tenure, is considered prospective for exactly this style of mineralisation.
The West Arunta region is described in the announcement as “one of Australia’s most exciting emerging mineral regions.” It has attracted growing attention as systematic exploration begins to reveal the scale of structural targets that have remained largely untested.
What makes Tali’s position significant is the sheer length of the corridor available to it. Within the company’s tenure, there is approximately 90km of untested strike along the Lake Mackay Fault Zone. Pitting pKDD001 against the Khya gravity-magnetic target represents Tali’s maiden diamond drill test at the target.
The GSWA co-funding grant adds a useful credibility signal for investors. Government geological agencies award EIS grants on a competitive basis, targeting programs with genuine scientific merit and prospectivity. A $270,000 commitment from GSWA indicates independent recognition that the Khya target warrants rigorous testing.

What investors should watch for next
Results from pKDD001 will be released as they become available, and this hole is part of a broader 2026 multi-prospect exploration campaign across the West Arunta Project. The four things worth monitoring as this program progresses:
- Assay results from pKDD001 — the primary near-term catalyst for Tali
- Downhole geophysical or geological updates from the 700m hole as drilling advances
- Additional drill targets along the Lake Mackay Fault Zone — the company has flagged that this first hole will inform its understanding of the broader structure
- Further GSWA or government co-funding announcements that may support subsequent programs
The MD’s note that Khya moved from concept to drill-ready in under 12 months is worth filing away as context. Execution pace matters in junior exploration, where delays between target generation and drill testing can stretch years. The remaining 90km of untested strike along the fault zone means the pipeline ahead is substantial relative to what has been tested so far.
Results are pending, and no assay data has been released at this stage. What this hole delivers at depth will shape how Tali allocates its next round of exploration effort along one of Western Australia’s more intriguing underexplored structural corridors.
