Shares of Tali Resources Ltd (ASX:TR2) fell 13.79% to $0.25 during the trading session on 20 October 2026. Separately, on 13 October 2026, the company released an overview of about 9,000 metres of planned aircore drilling across the Don Juan-Alakol trend and other prospects in the West Arunta region, due to begin in October. The share price move and the release occurred on different dates and are not linked in this article.

About Tali Resources Ltd

Tali Resources is a Subiaco, Western Australia-based explorer focused on the West Arunta region. Its critical minerals targets include carbonatite-style systems, which can host niobium, rare earth elements, titanium and phosphorus. The company’s Don Juan and Alakol prospects lie within a 45 kilometre alkaline ultramafic intrusive complex.

Drilling program

Approximately 5,500 metres of aircore drilling will test seven high-priority targets within the Don Juan-Alakol trend for the first time. A further 3,500 metres will test five targets along the Central Australian Suture: Caspian North, Caspian North-East, Hutt West, Verde East and Verde West. The combined program is about 9,000 metres.

Targets at Don Juan include Don Juan South-East, a gravity high with a concentric magnetic rim interpreted as a potential 450 by 600 metre pipe-like intrusion; Don Juan East, a body of about 5.4 by 4.8 kilometres; Don Juan South; and Don Juan West, an 8.9 kilometre dyke. At Alakol, drilling will test the western edge, Alakol B and Alakol C.

Exploration history at Don Juan

Toro Energy completed soil, rock chip and lag sampling in 2011, which identified nickel and chromium responses. A rock-chip sample from altered wall rock returned up to 3.2% total rare earth elements. In 2019 Niobium Holdings Pty Ltd completed soil sampling, and later Reverse Circulation Drilling at Don Juan and Alakol, where seven of eight holes intersected aillikite.

That drilling tested only about 7 kilometres of the 45 kilometre system. Intersections included 19 metres at 853 ppm rare earths plus yttrium from 82 metres, and 48 metres at 847 ppm from 76 metres. The release notes that later heritage surveys identified areas where access is no longer available, although more than 35 kilometres of the system lies outside the inaccessible area.

Geological rationale

Aillikite is a carbonate-rich ultramafic lamprophyre that is commonly associated with carbonatites. The company states that recent geochronology places niobium and rare earth-bearing carbonatites in the West Arunta at approximately 830 to 820 million years, overlapping with the reported age of the Webb aillikite pipes. It also refers to discoveries by other explorers about 80 kilometres to the north-east of Don Juan.

Sector backdrop

The West Arunta has attracted exploration interest because of niobium and rare earth discoveries reported by other companies, and carbonatite-related systems are also pursued for critical minerals used in magnets, electronics and steel. Cover over the region means geophysics and drilling are the main tools to test targets.

Remote exploration in central Australia involves heritage, access and logistics considerations.

Risks shareholders should weigh

The drilling targets are interpreted from geophysics and historical work, and there is no certainty that drilling will find carbonatite or economic mineralisation. Aircore drilling is shallow, and assay results may take time to be reported.

Heritage surveys have already removed parts of the Don Juan system from the accessible area. The company will need funding to continue exploration. At $0.25, the 13.79% fall on 20 October 2026 illustrates the Volatility that can affect explorers in a speculative field.

What’s next

The program is planned to start in October. Samples will be assayed and reported as results become available, with the company stating it is focused on accessible strike extensions of the Don Juan-Alakol system.
