Brazilian Critical Minerals (ASX:BCM) has successfully extracted rare earths from its in-situ recovery plant field trial at the Ema Project in Brazil. The $14.41 million market capitalisation company says the field-based extraction validates the in-situ recovery (ISR) process at Ema, marking a ‘significant step forward’ for the project’s development. Brazilian Critical Minerals is a junior mineral explorer focused on its assets across Brazil considered prospective for rare earths and critical minerals.
Managing Director Andrew Reid says the field trials have exceeded the company’s expectations, confirming that ISR can reliably mobilise and extract rare earths under real-world field conditions. The company believes this positions the Ema Project as a transformative development in the global rare earth supply chain, delivering high ESG performance and sustainable extraction practices. The rare earths were recovered using a low-concentration magnesium sulphate solution, supporting the company’s commitment to environmentally responsible and sustainable mining practices.
Brazilian Critical Minerals plans to continue field trials to collect as much rare earth as possible and produce a mixed rare earth carbonate suitable for offtake analysis. A Bankable Feasibility Study will also be carried out in the coming weeks, alongside ongoing offtake discussions.
Looking ahead, the company intends to progress environmental and mining permits with state regulators. Reid noted the company will now focus on completing the current field trial program, initiating the Feasibility Study, and progressing key workstreams including permitting, financing, and offtake negotiations.
