Audalia Resources Limited (ASX:ACP) has formally lodged a Mine Development and Closure Proposal (MDCP) with the Western Australian Department of Mines, Petroleum and Exploration (DMPE) for its Medcalf Titanium-Vanadium-Iron Critical Minerals Project, located approximately 100 kilometres southwest of Norseman in Western Australia.

Key Points

MDCP formally lodged with the Western Australian Department of Mines, Petroleum and Exploration (DMPE) for the Medcalf Critical Minerals Project.
The project received an EPA Ministerial Statement approving it on 4 July 2024, with the MDCP representing the next major regulatory approval step.
The Probable Ore Reserve stands at 11.77 million tonnes grading 11.01% TiO2, 53.80% Fe2O3, 0.61% V2O5, 8.82% Al2O3, and 15.90% SiO2.
Final product is planned to be transported 150km by on-highway trucks to the port of Esperance for shipping to customers outside Australia.

MDCP Lodgement and Project Location

The MDCP covers the Medcalf Titanium-Vanadium-Iron Project, situated approximately 100 kilometres southwest of Norseman in Western Australia and approximately 45 kilometres south of the Maggie Hays nickel mine. The proposal also includes plans for a private access road, 74 kilometres in length, to be constructed westerly from the Coolgardie to Esperance Highway to the project site. The MDCP sets out the proposed development and operation of the project, including infrastructure requirements, environmental management, rehabilitation, and closure measures, subject to DMPE approval and receipt of all other required approvals.

Ore Reserve and Mineral Resource Details

The MDCP lodgement follows the company's JORC (2012) compliant maiden Ore Reserve Estimate, released on 30 January 2026, based on the September 2025 Mineral Resource Estimate. The Ore Reserve comprises a Probable category of 11.77 million tonnes at 11.01% TiO2, 53.80% Fe2O3, 0.61% V2O5, 8.82% Al2O3, and 15.90% SiO2, with no Proved category reported. The reserve is based on a 6% TiO2 cut-off grade and preliminary open cut mining methods using conventional drill and blast mining. The filing states the potential to produce High Titanium Lump Ore and High Titanium Fine Ore for use in blast furnace liner protection via a direct shipping operation.

Service Provider Partnership and Project Progress

According to the filing, Audalia is partnering with a Western Australian mining, crushing, and haulage service provider with extensive experience in the Dundas area and Esperance Port facilities. The collaboration is aimed at enhancing the project feasibility study with inputs from the service provider's real-time operating experience, with the filing describing a projected 10-year project. CEO and Executive Director Brent Butler stated in the filing that the MDCP details further develop the company's understanding of how the Medcalf Project is required to be operated to be safe and environmentally compliant during operations. The company stated it continues to work towards a final investment decision.
