Brazilian Important Minerals Restricted (ASX: BCM) (“BCM” or the “Firm”) is happy to announce that it has now efficiently leached, extracted and precipitated uncommon earths from its in-situ restoration (ISR) pilot discipline trial on the Ema undertaking.
Highlights
- First REEs efficiently recovered underneath real-world situations: Uncommon earth components have been leached, extracted, and precipitated immediately from the Ema deposit utilizing in-situ restoration (ISR) strategies
- Technical viability confirmed: This profitable field-based extraction validates the ISR course of at Ema and marks a major step ahead for the undertaking’s growth
- Environmentally pleasant leaching resolution used: The REEs have been recovered utilizing a low- focus (0.5M) magnesium sulfate (MgSO₄) resolution, supporting BCM’s dedication to environmentally accountable and sustainable mining practices
This achievement strengthens BCM’s place as a pacesetter in low-impact, next-generation uncommon earths manufacturing and demonstrates the potential for ISR to supply a scalable, low-cost, and environmentally superior different to standard mining strategies.

Determine 1. Precipitated solids immediately within the discipline after in-situ leaching. Small quantities of reagent added to uncommon earth wealthy resolution inflicting the uncommon earths and impurities to precipitate (cloudy materials) in a beaker immediately adjoining to extraction wells.
Andrew Reid, Managing Director, commented:
“Our discipline trials have now conclusively demonstrated that uncommon earth components might be efficiently leached, recovered, and precipitated from resolution through in-situ restoration (ISR) at Ema, exceeding our expectations on all fronts. This represents a serious technical and operational milestone and a vital step in de-risking the undertaking.
It confirms that ISR can reliably mobilize and extract uncommon earths underneath real-world discipline situations, positioning the Ema Challenge as a transformative growth within the world uncommon earth provide chain— delivering excessive ESG efficiency and sustainable extraction practices.”
“We now look forward to finishing the present discipline trial program, initiating the feasibility examine, and progressing key workstreams together with allowing, financing, and offtake negotiations.
Ema stays uniquely positioned outdoors Southeast Asia as the one recognized uncommon earth undertaking able to working through ISR with exceptionally low capital and working prices. The February 2025 Scoping Research highlighted Capex of simply US$55M and Opex of simply US$6.15/kg TREO while capable of produce 4,800tpa of TREO or 1,800tpa of key magnet components in a blended uncommon earth carbonate product.”
