Set for rapid growth, BCM is well positioned to benefit from nine large REE-focused tenements near Apui Town and a precious metals discovery at Tres Estados.
Brazilian Critical Minerals is a precious metals and rare earth exploration, development, and technology company based in Perth, Australia, with assets and operations in northern Brazil.
The company’s two projects, Tres Estados and EMA, are in Brazil’s Amazonas state. Tres Estados contains 44 drill holes within magnetic geochemical anomalies inside the 8,172-hectare tenement. EMA contains in excess of 200 REE drill holes within an extensive 189 square kilometre rare earth discovery.
The company’s primary mission is to create long-term value for its key stakeholders, including local communities and governments, valued employees, and shareholders. It focuses on building a sustainable mining region, maintaining a safe and healthy environment, and maximising social benefits where it operates.
The Tres Estados Precious Metals Project
The Tres Estados Precious Metals Project is located 60km southeast of Apui, with year-round access by gravel roads. The area is situated over the mapped Colider group, a prolific volcanic Proterozoic unit for gold and precious metal deposits.
The tenement is located over a series of gabbroic intrusions defined by prominent E-W and NE-SW magnetic anomalies, local gold-in-soil geochemical anomalies and shallow artisanal gold workings.
The Tres Estados project has a JORC resource containing 725,230 ounces of combined platinum, palladium, iridium, rhodium, and gold.
An innovative bioleaching process has indicated significant resource upgrades that unlock the precious metals for further recovery. The bioleach testing of drill hole TED 020 showed nearly a 10-fold increase in availably palladium and gold to 16.2 gr/t of pd and au.
Starting with Tabocal, the resource will be reassessed in 2024 using the bioleach as pretreatment, followed by standard fire assaying.
The EMA Rare Earth Project
The EMA Rare Earth Project is located 30km south of Apui, Brazil, with year-round access by gravel roads. Like the Tres Estados project, the area is also situated over the mapped, precious metal heavy Colider group.
It covers 189km2 of weathered unconsolidated Rhyolite REE-bearing mineralisation containing grades up to 2,631 ppm of TREO.
Extensive auger drilling was conducted during 2023, and as a result, a JORC resource is expected shortly after the final assays are received. The Ema ionic deposit had excellent precious metals recoveries when leached with a 2% ammonium sulphate solution.
The Apui tenements, covering 510km2 , have also shown excellent grades up to 2747 ppm of TREO and 7% K2O in the initial drill sampling at ENE Apui.
A large drilling programme is envisioned for the 2024 drilling season to continue defining this massive new discovery.
Environmental, social and governance responsibilities
Brazilian Critical Minerals believes that operating in a sustainable manner is essential to delivering the company’s core strategy and objective of advancing the discovery of precious metals.
The company’s sustainability strategy is based on its four sustainability pillars, which are:
- Environment: Mining inevitably has an impact on the environment. Therefore, the company is responsible for managing, mitigating, and rehabilitating to limit any negative effects of its activities;
- Protecting health and safety: Health and safety are fundamental responsibilities towards the workforce and local community. Robust safety measures are in place;
- Creating economic benefit: To successfully explore and mine precious metals in the regions where Brazilian Critical Minerals operates, it is critical to share the benefits of such activities with the local communities; and
- Respecting human rights: Brazilian Critical Minerals is a global company operating in remote Brazil. It acknowledges its responsibility and opportunity to contribute and promote high human rights standards in all operations.
