Ark Mines Signs MoU to Trial Rare Earths Processing at Sandy Mitchell

The latest update is out from ARK Mines Ltd ( (AU:AHK) ).

Ark Mines has signed a memorandum of understanding with a processing technology provider to run a monazite cracking trial on ore from its Sandy Mitchell Rare Earths Project in Queensland, starting in February 2026. The program will use an existing low-cost process to recover thorium and rare earth elements, including neodymium and praseodymium, and will cover the full chain from cracking to production of rare earth oxides and refined thorium.

The small-scale trial is designed to deliver integrated chemical analysis, radionuclide profiling and separation chemistry across three target materials, with up to three process variations tested for each. Successful results could lead to a scaled pilot plant, helping de-risk downstream processing, validate Ark’s processing route and support engagement with potential end users and offtake partners in a market increasingly focused on secure supplies of critical minerals.

The initiative comes as thorium, neodymium and praseodymium gain prominence as strategic minerals due to their roles in energy security, electric vehicles, wind turbines and defence applications. By advancing a processing pathway for its monazite ore, Ark aims to strengthen Sandy Mitchell’s role as a potential long-life supplier of these materials into global supply chains and to improve its competitive positioning in the rare earths sector.

The most recent analyst rating on (AU:AHK) stock is a Hold with a A$0.46 price target. To see the full list of analyst forecasts on ARK Mines Ltd stock, see the AU:AHK Stock Forecast page.
