Ema is geologically unique among Brazilian rare earth projects, with characteristics closely comparable to the world-class ionic clay deposits of southwest China — the largest and most important source of rare earths globally. The project covers 189km² of felsic volcanic terrain, with only ~45% of the ground explored to date, leaving significant potential for expansion.

The EMA Project in Northern Brazil is Brazilian Critical Minerals’ flagship asset and one of the largest ionic clay rare earth resources outside China. With a global Mineral Resource Estimate of 943Mt @ 716ppm TREO, including a 341Mt high-confidence starter zone, Ema has the scale and quality to supply magnet rare earths (Nd, Pr, Dy, Tb) critical to clean energy, electrification, and high-tech industries.

Bankable Feasibility Study Confirms Exceptional Economics:

The Bankable Feasibility Study (BFS) confirms Ema's status as a tier-1 project with:

Post-tax NPV8 of US$1.47B and IRR of 105% 

Stage 1 upfront capital requirement of US$74M (inclusive of contingency) 

Life-of-Mine operating costs of US$8.84/kg TREO – amongst the lowest globally 

Annual production averaging ~5,500t TREO over a 20-year mine life

EMA-EMA East REE Project – Auger Holes On 800m Centres and infill drilling status over 82sqkm with high grade 12km2.

BCM is pioneering in-situ recovery (ISR) for rare earths outside China, providing a low-cost, low-impact alternative to conventional mining. ISR eliminates the need for open pits, haulage, or large processing plants, offering:

Green reagent chemistry with no deleterious by-products

Recent pilot trials confirmed strong permeability and rapid solution flow through the clays, with recoveries of up to 74% magnet REEs and 62% total REEs, significantly above Scoping Study assumptions.

With an updated Mineral Resource Estimate, successful ISR field trials, and permits in place for water usage and environmental baseline studies, BCM is advancing Ema towards feasibility studies and offtake discussions. The project’s combination of scale, ultra-low costs, and sustainable extraction positions it to become a strategic supplier of magnet rare earths to global markets.
