Project

Serra Negra Rare Earth/Niobium Project

Carbonatite-Hosted REE Project Strategically Located in a Tier 1 District

Impulsionando o futuro da exploração de terras raras

Grade

Significant rare earth element (REE) mineralsation identified, with demonstrated potential for grade and widths

Scale

District-scale carbonatite complex (10km diameter)

Address

Located in Tier 1 Mining Jurisdiction in the heart of Brazil's Minas Gerais State

Team

Highly successful and credentialed board and management team, responsible for establishing Bellevue Gold (ASX 200), Firefly Metals (ASX 300) and Andean Silver

Project Highlights

One of Brazil's Largest Carbonatite Systems

Carbonatite-hosted REE + Niobium systems are scalable, and historically underpin world-class mines

  • Tier-1 Carbonatite Complex

    10km diameter intrusive complex, largest known carbonatite in the district

  • Comparable geology to proven Brazilian analogues

    Same district as the World-class Araxa and Catalao Carbonatite Complexes (ASX:SGQ, CBMM, Mosaic, CMOC)

  • Strategically located to align with Western supply chains

    Patrocinio within 20km – rail, road access, power, water, workforce and services

  • Brazil emerging as a global hub for the REE Industry

    Minas Gerais State actively supporting new entrants and established critical mineral businesses

Exploration Results

Confirmed High-Grade REE Mineralisation

Independent sampling by Oceana during acquisition due diligence validated wide REE and niobium mineralised intervals across multiple drill holes in the Serra Negra carbonatite complex.

* Grab samples are selective in nature and not representative of continuous mineralised intervals. Independent laboratory assays by ALS utilised four-acid digestion ICP-AES, with REE over-limit samples analysed by ICP-MS.

Emerging Target

Niobium Upside Alongside REE

An emerging niobium (Nb₂O₅) target has been identified from due diligence sampling, supported by independent laboratory assays. Niobium mineralisation occurs in carbonatite units adjacent to the main REE zones, with results comparable to Brazil’s world-class niobium districts.

The project demonstrates potential for large-scale, bulk-tonnage niobium upside — a commodity that has received limited historical focus at Serra Negra, despite the complex sharing structural and lithological characteristics with CBMM’s Araxá operation, which supplies approximately 80% of the world’s niobium.

  • An emerging niobium (Nb₂O₅) target has been identified
  • Niobium mineralisation occurs in carbonatite units adjacent to the main REE zones
  • Comparable to Brazil’s world-class niobium districts in the Alto Paranaíba Igneous Province (APIP)
  • Potential for large-scale, bulk-tonnage niobium upside, with limited historical focus
