Key Highlights

  • Great Dirt Resources (ASX:GR8) reported that soil sampling on a 200 by 200 metre grid at the Pilbara Project returned 75 anomalous lithium results from 776 samples, with three Priority 1 targets overlying potassium radiometric anomalies.
  • Lithium correlated strongly with caesium and rubidium across 52 samples, consistent with lithium-caesium-tantalum pegmatites, and the tenement lies 43 kilometres from Pilbara Minerals' Pilgangoora project.
  • Rock-chip sampling at the NSW Doherty and Basin manganese projects returned up to 55.1% manganese at Neranghi and 45.8% at the Doherty Mine dump.
  • Cash was A$3.4 million at 30 September 2026, representing about 8.2 quarters of funding at the current rate of spending, with no drilling yet scheduled.

Great Dirt Resources is chasing lithium targets in Western Australia's Pilbara because soil sampling in August 2026 defined nine anomalies, three of them ranked as priorities, on a tenement it holds outright. The results are early, and no drilling has been scheduled.

What the company does

Great Dirt Resources Ltd is a mineral explorer admitted to the ASX in November 2023 and classified in the Materials sector. Its shares are ordinary shares, and it has no operating revenue.

It holds two main assets. The Pilbara Project, exploration licence E45/6863, covers about 67.5 square kilometres in the East Pilbara lithium province. The Doherty and Basin manganese projects, in exploration licence EL9527 in northern New South Wales, cover 168 square kilometres.

The Pilbara soil results

On 21 October 2026 the company reported assays from soil sampling on a nominal 200 by 200 metre grid. Of 776 results, 75 exceeded its lithium oxide anomaly threshold of 47.9 parts per million, and the peak was 131 parts per million in target T1.

Lithium correlated strongly with caesium and rubidium, a pattern the company says is consistent with lithium-caesium-tantalum pegmatites. Fifty-two samples were anomalous in all three elements.

Three Priority 1 targets, T1, T5 and T2, overlie potassium radiometric anomalies, and most lie under thin sand cover. The tenement is about 43 kilometres from Pilbara Minerals' Pilgangoora project.

The Quarterly Report cites 805 samples collected, while the assay announcement refers to 777, so the exact count should be checked. Soil anomalies are only indicators. Many do not lead to mineralisation, and the company has not drilled the ground.

Manganese in New South Wales

On 20 July 2026 Great Dirt reported 14 rock-chip samples from the Doherty Mine area and Neranghi. Neranghi returned up to 55.1 per cent manganese, and Doherty Mine dump samples reached 45.8 per cent.

The company notes that rock-chip samples are selective and not representative of average grade. Historical production at Doherty is stated as about 6,000 tonnes in one section and 9,000 in another. Its Annual Report says rock-chip assays reached 51.8 per cent manganese and 24 priority targets were identified.

The finances

For the year to 30 June 2026 the company reported a loss after tax of A$19.14 million, against A$428,424 a year earlier, in a year when Tim Laneyrie joined as an executive director and Martin Helean moved from managing director to non-executive director. About A$18.58 million of that was non-cash share-based payments expense, so the loss mostly reflects Equity awards rather than spending on exploration.

Cash was A$3.81 million at 30 June 2026. In the September 2026 quarter, operating cash outflow was A$201,000, exploration payments were A$214,000 and cash at 30 September was A$3.401 million, which the company puts at about 8.2 quarters of funding.

The annual report says the group relies on equity raisings and option exercises. During the September quarter, exercise of 25,000 Options at A$0.25 raised A$6,250. In the year, the company also divested its Nullagine tenements for A$40,000 and received an R&D Tax Incentive refund of A$315,282.

Risks and next steps

The next phase is infill soil sampling at 100-metre spacing, geological mapping, rock-chip sampling and heritage surveys with Traditional Owners. Reconnaissance aircore or reverse-circulation drilling of T1, T2 and T5 depends on results and approvals, and the company gave no dates.

Risks include exploration failure, lithium price swings, approvals, and dilution. The annual report lists about 29.5 million options on issue and a performance-rights grant of more than 21 million, which could increase the share count if exercised or vested. Total shares on issue were not stated in the documents reviewed.

The Annual General Meeting is at 10:00am AWST on 17 November 2026 in West Perth.
