- Mineralization: Ionic Adsorption Clay (IAC)
- Location: Minas Gerais, Brazil
Man of War
A Tier-1 Asset in Brazil's Premier Critical Minerals District
The Poços de Caldas alkaline complex covers approximately 800km², constituting the largest occurrence of alkaline rocks in South America.
By securing a dominant land position in this district, the Man of War Project leverages existing infrastructure and proven geological continuity to minimize development risk.
Unrivaled Scale
A District-Scale Ionic Clay Powerhouse
Strategically located in Minas Gerais, the Man of War Project represents a globally significant REE discovery. With a massive 1.35 billion tonne maiden resource, the project offers the volume and continuity required to become a long-term cornerstone of the Western magnet metal supply chain.
- 1.35Bt @ 3,437 ppm TREO
- Exceptional 74m High-Grade Thickness
- 17.7 km² of Proven Mineralization
Strategic Advantage
Exceptional Niobium Multi-Commodity Potential
Unlike typical REE deposits, Man of War hosts high-grade Niobium credits across its primary targets. This unique synergy provides a robust economic buffer and a path to industry-leading margins through the production of high-value superalloy feedstocks.
- Peak Niobium Grades of 2,274 ppm
- Dual-Revenue Stream Potential
- Strategic Aerospace Industry Demand
Clean Processing
The Lowest Quartile Cost Curve via Salt-Desorption
Our processing flowsheet utilizes simple, ambient-temperature salt desorption. This avoids the energy-intensive "acid-bake" methods used in hard-rock mining, resulting in a clean Mixed Rare Earth Carbonate (MREC) with no radioactive tailings and a significantly reduced carbon footprint.
- Ambient Temperature Extraction
- Zero Radioactive Waste Profile
- Minimal Chemical Reagent Consumption
Accelerated Path
Aggressive Roadmap to Tier-1 Production
OBY is fast-tracking development through systematic de-risking. With infrastructure already in place and a streamlined permitting environment in Minas Gerais, we are focused on delivering a Preliminary Economic Assessment (PEA) that validates the project's status as a world-class critical minerals hub.
- PEA Targeting Mid-2026
- Pro-Mining Jurisdiction (Minas Gerais)
- Established Logistics & Power Hub
The 20-year LOM schedule delivers industry-leading operating costs, prioritizing high-grade ionic horizons to maximize NPV and accelerate capital recovery.
