Brazilian Critical Minerals (ASX:BCM) has extracted rare earths from its in-situ recovery plant field trial at the Ema Project in Brazil under real world conditions.
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.
Managing Director Andrew Reid says the field trials have exceeded the company’s expectations on all fronts.
“It confirms that ISR can reliably mobilise and extract rare earths under real-world field conditions, positioning the Ema Project as a transformative development in the global rare earth supply chain — delivering high ESG performance and sustainable extraction practices,” Reid says.
“We now look ahead to completing the current field trial program, initiating the Feasibility Study and progressing key workstreams including permitting, financing, and offtake negotiations.”
The rare earths were recovered using low-concentration magnesium sulphate solution, which supports Brazilian Critical Minerals commitment to environmentally responsible and sustainable mining practices.
Brazilian Critical Minerals plans to continue field trials to collect as much rare earth as possible, as well as produce a mixed rare earth carbonate suitable for offtake analysis.
A Bankable Feasibility Study will also be carried out within the next few weeks, while also offtake discussions continue.
Further, the company has indicated it will seek to progress environmental and mining permits with state regulators.
Brazilian Critical Minerals is a junior mineral explorer focused on its assets across Brazil considered prospective for rare earths and critical minerals.
