Brazilian Critical Minerals Limited has appointed Altris Engineering to lead a six-to-nine-month feasibility study of its Ema Rare Earths project in northern Brazil. The integrated study targets process and infrastructure optimization, potentially unlocking a low-cost, near-term source of rare earth feedstock.

Brazilian Critical Minerals Limited has announced that it has appointed Altris Engineering as the lead consultant for its Ema Rare Earth Bankable Feasibility Study in northern Brazil. The study, expected to be completed within six to nine months, will focus on both the process plant and associated non-process infrastructure. The company has enlisted the expertise of Altris Engineering alongside established technical partners such as ANSTO and WSP to deliver a comprehensive engineering study that will underpin upcoming project financing discussions. The feasibility study will involve a detailed review of previous metallurgical test work, finalization of process flowsheets, and the design of both operational components and supporting infrastructure such as offices, water treatment facilities, and power supply systems. ANSTO will conduct advanced process flow sheet optimization using extracted pregnant liquor solutions, while WSP will perform detailed hydrogeological modeling and design aspects related to reagent injection and recovery systems. Ground activities scheduled over the next several months include geotechnical investigations, LiDAR surveying for field design accuracy, and access road improvements, underlining the practical steps toward progressing the project. The Ema Project is notable as the only rare earth in-situ recovery development of its kind in the Western world and is positioned with a comparatively low capital expenditure of US$55 million. The project’s technical fundamentals are reinforced by an indicated and inferred mineral resource estimate totalling 943 million tonnes at a cut-off of 500 ppm, with metallurgical recoveries averaging around 68% for major rare earth oxide components. This strong technical basis, combined with the proven track records of the partner teams, underscores the project’s potential to become a near-term, cost-competitive source of rare earth feedstock. In terms of market sentiment, the news carries a bullish tone. The strategic appointment of Altris Engineering coupled with the involvement of high-profile technical partners is likely to inspire confidence among investors, particularly as the low capital cost and robust resource estimates signal a favorable risk-reward profile for future project financing. However, a bearish perspective might note that the completion of the feasibility study over the coming months is subject to inherent uncertainties typical of early-stage mineral project developments. Overall, the integration of advanced technical studies and the staged progression towards DFS is seen as a positive step for Brazilian Critical Minerals Limited, though investors should remain mindful of development risks common to projects in this sector.
