Ark Mines Sandy Mitchell Rare Earths Development

under development

Ark Mines Sandy Mitchell rare earths project is a placer deposit system in Queensland, Australia, with a measured resource of 71.8 million tonnes grading 1,732 ppm monazite equivalent. The project benefits from natural pre-concentration, enabling simplified gravity-based beneficiation processing to produce a 51.9% total rare earth oxide concentrate. It has potential for resource expansion to 1.3-1.5 billion tonnes and includes co-product revenue streams from zircon, rutile, ilmenite, xenotime, and thorium. The project aims for production start in late 2027 with a pre-feasibility study targeted for Q1 2026. Queensland Investment Corporation has invested $4.5 million in royalty-linked capital and equity to support development.
