Great Dirt Uncovers Lithium Anomalies in Pilbara, Advances NSW Manganese Exploration
Great Dirt Resources reports promising lithium soil anomalies in Western Australia's Pilbara region and progresses manganese exploration in New South Wales, supported by a solid cash position of $2.4 million.
- Initial Pilbara soil sampling reveals lithium anomalism
- Ongoing manganese exploration and research at NSW Doherty Project
- Strategic evaluation of new tenements and critical minerals acquisitions
- Strong cash reserves of $2.4 million with disciplined expenditure
- No production activities; focus remains on exploration and portfolio growth
Pilbara Lithium Anomalies Signal New Exploration Potential
Great Dirt Resources Limited (ASX – GR8) has reported encouraging initial results from its Pilbara soil sampling program, highlighting lithium anomalism within Exploration Licence E45/6863. The program, involving 83 soil samples spaced every 200 meters, identified a zone of lithium enrichment in the southern half of the tenement. This anomalism coincides with elevated levels of aluminium, rubidium, and tin, suggesting geological fractionation processes favorable for lithium-caesium-tantalum (LCT) mineralisation.
Located near established lithium projects such as Wildcat Resources’ Tabba Tabba and Pilgangoora Lithium Projects, Great Dirt’s tenement area has historically seen limited lithium-focused exploration despite its proximity to these major deposits. The new findings open avenues for more detailed soil sampling and targeted exploration campaigns to delineate potential lithium resources.
Advancing Manganese Exploration in New South Wales
Meanwhile, Great Dirt continues to advance its manganese exploration efforts at the Doherty Project in northern New South Wales. The company is executing a multi-phase research program integrating geochemical, geophysical, and petrological analyses to refine the understanding of the manganese mineral system. This approach aims to test hypotheses about the deposit’s origin, potentially shifting from a secondary enrichment model to an exhalative genesis, which could unlock district-scale mineralisation potential.
The program aligns with Australia’s Critical Minerals Strategy 2023–2030, emphasizing the importance of manganese for metallurgical and battery applications. Eligible research activities may also benefit from government R&D tax incentives, supporting the company’s exploration expenditure efficiency.
Strategic Growth and Financial Position
Great Dirt is actively pursuing strategic growth initiatives, including evaluating additional tenements and potential acquisitions across critical minerals and base metals. This expansion strategy aims to complement the company’s existing manganese and lithium portfolios, positioning it well within the evolving critical minerals sector.
Financially, the company reported a robust cash position of $2.4 million at the end of September 2025, with quarterly cash outflows aligning with management expectations. No production or development activities were undertaken during the quarter, underscoring the company’s current focus on exploration and project advancement. Payments to related parties, primarily directors’ fees, totaled $91,000 for the quarter.
Looking Ahead
Great Dirt’s recent exploration results and strategic initiatives suggest a company positioning itself to capitalize on the growing demand for critical minerals. The lithium anomalism in Pilbara and the refined manganese exploration in NSW could, if further confirmed, underpin future resource development. Investors will be watching closely as the company progresses its next phases of sampling, geophysical surveys, and potential acquisitions.
Bottom Line?
Great Dirt’s exploration momentum and strategic positioning set the stage for potential critical mineral discoveries that could reshape its growth trajectory.
Questions in the middle?
- Will subsequent soil sampling confirm and expand the lithium anomalism in Pilbara?
- How will the refined geological model at Doherty influence manganese resource estimates?
- What new tenements or acquisitions might Great Dirt announce to complement its portfolio?
