AR3 advances Koppamurra with pilot-scale processing at ANSTO

Highlights:

• Strategic First-Mover Advantage: AR3 to be the first industry partner to access ANSTO’s new pilot-scale rare earth processing facility, not only saving time and money in advancing the Koppamurra Project but also positioning the Company at the forefront of Australia’s emerging group of ionic clay-hosted rare earths producers.

• Accelerating Commercial Pathway: Pilot-scale operations to process ~25 tonnes of Koppamurra ore producing ~35kg of Mixed Rare Earth Carbonate (MREC) — a key step toward scaling operations and future production.

• Government-Backed Funding: Pilot program co-funded under AR3’s $5 million Australian Government grant from the International Partnerships in Critical Minerals Program.

• De-Risking Project Development: Enables validation of Koppamurra’s full process flowsheet, real-time process optimisation, and generation of engineering data critical for feasibility and design.

• Offtake Readiness: Production of MREC samples for testing and qualification by potential offtake and strategic partners, supporting Koppamurra’s transition to binding commercial agreements.

• Strengthening Australia’s Sovereign Capability: Collaboration with ANSTO advances a domestic rare earth supply chain aligned with the Future Made in Australia initiative and the Australian Critical Minerals Strategy.

• Clear Development Timeline: Koppamurra Pre-Feasibility Study on track, with pilot operations scheduled for Q2 2026 and Definitive Feasibility Study to follow later in 2026.
