Remorse Iron Deposit Yields Up to 68.8% Iron Concentrate in First Tests

Strong Start for Remorse Iron Metallurgy

Tempest Minerals Limited (ASX: TEM) has delivered encouraging first metallurgical results from its Remorse Iron discovery, part of the broader Yalgoo Project in Western Australia. The initial Davis Tube Recovery (DTR) testing on a composite sample from the deposit has produced iron concentrate grades reaching 68.8% Fe at a fine grind size of P80 25 microns. This outcome is notable not only for the high iron content but also for the low levels of impurities such as silica, aluminium, manganese, and phosphorus, which bode well for downstream processing.

Context of the Remorse Deposit

Discovered in 2024 through a targeted drilling campaign, the Remorse Deposit is a large magnetite iron formation situated on the eastern side of the Yalgoo Project. The project area spans over 1,000 square kilometres and is located near several established mining operations focused on base metals, gold, and iron. The deposit itself was initially identified during exploration for base metals, but drilling revealed significant high-grade magnetite mineralisation with iron grades up to 39% in situ.

Metallurgical Testing and Methodology

The metallurgical testwork was conducted by Independent Metallurgical Operations (IMO) at the SGS Metallurgy laboratory in Welshpool, Western Australia. The first composite sample, weighing 50 kilograms, was prepared from nine one-meter intervals of reverse circulation drill rejects. The sample underwent staged crushing and grinding to various particle sizes, followed by DTR testing to assess magnetic separation efficiency. The results demonstrated excellent recoveries and concentrate grades, confirming the deposit's potential for producing high-quality iron ore.

Strategic Partnerships and Next Steps

Tempest Minerals has also formalised a memorandum of understanding with GreenSteel and Iron Pty Ltd, a growing steel developer in the Mid-West region, to explore processing synergies. This collaboration could accelerate the pathway to development by leveraging shared infrastructure and expertise. The company expects to receive further metallurgical results from additional composite samples in the coming weeks, which will inform ongoing resource assessments and project planning.

Looking Ahead

While these initial results are promising, they represent an early stage in the metallurgical characterisation of the Remorse Deposit. Tempest plans to continue refining the concentrate quality through further testwork and petrological studies. The integration of these data into the broader resource model will be critical for advancing the project towards feasibility and eventual production.
