Highlights

• China currently controls over 90% of rare earth refining, making global supply diversification critical.
• Madagascar's Ampasindava deposit represents a significant non-Chinese ionic adsorption clay (IAC) rare earth resource.
• The project's future success depends on a definitive feasibility study, secured offtakes, and demonstrating environmental sustainability.

Global Mining Review’s recent piece (opens in a new tab) gets the macro picture right: China controls over 90% of rare earth refining and a majority of IAC (ionic adsorption clay) mining. Diversifying supply is not just industrial policy—it’s risk management. Madagascar’s Ampasindava (opens in a new tab) deposit under development by Harena Resources (opens in a new tab) is one of the better-known non-Chinese IAC resources, with JORC-verified estimates north of 600,000 tonnes REO in-situ reports Ivan Murphy, non-executive chairman of the company. The processing advantage of IAC (low strip ratio, simpler leaching) over hard rock is a fact, and the project’s completion of >20,000 m of drilling, hundreds of holes, and a completed pre-feasibility study are verifiable milestones.

The Gloss and the Gray Areas

The article’s portrayal of Ampasindava as “rare earth mining as it should be” leans from fact into sales pitch. While IAC mining can be less energy-intensive, the environmental footprint depends heavily on leachate management, water use, and post-mining restoration—none of which are fully proven at this site. Calling ammonium sulfate “benign” is a stretch without water quality impact data. The assertion that this project will be “central” to U.S. or EU supply security is speculative until there are offtake or processing partnerships with actual Western magnet producers—none are mentioned.

Bias Under the Microscope

The piece reads more like an investor brochure than an independent editorial.  While the potential is there some hard realities need to be understood as well:

• What are Madagascar’s political and regulatory risk levels?
• What are the challenges associated with infrastructure and logistics hurdles from mine to market?
• What about processing dependency? Without non-Chinese separation capacity, the “secure supply” claim is questionable.
• CAPEX and financing specifics beyond a vague fundraising reference.

Investor Takeaway

Ampasindava is a legitimate, large-scale IAC play with significant exploration de-risking already done. But the leap from resource in Madagascar to magnets in Detroit, Hamburg, or Tokyo is non-trivial. Watch for:

• Definitive feasibility study (DFS) completion in 2026—cost structure will make or break competitiveness.
• Secured offtakes with non-Chinese processors—the real test of “secure supply.”
• Environmental and community impact data—regulators and ESG investors will demand it.

Until those boxes are ticked, consider this project promising but still in the “proof pending” column. This asset could emerge in the future as an important piece to the ex-China market puzzle, but a key question is when.
