Highlights

Oceana's 100%-owned Serra Negra project is a district-scale carbonatite complex of about 10 km in Minas Gerais, Brazil.
Re-assayed historic holes include 114m at 2.3% TREO, including 50m at 4.0%.
A 20,000m, four-rig drilling program is underway, targeting initial resource definition.
The company held about A$16.5 million cash with no debt as of 16 October 2026.

Oceana Metals Limited (ASX:OCN) has released a corporate presentation titled "Unlocking a World-Class Rare Earth Opportunity in Brazil". It outlines the company's 100%-owned Serra Negra project, located about 20 km from Patrocínio in Minas Gerais and near the established operations at Araxá, Salitre and Tapira.

Serra Negra Geology and Historic Results

Serra Negra is a district-scale carbonatite complex of about 10 km, described as the largest known carbonatite complex in the Alto Paranaíba Igneous Province. It was historically explored mainly for phosphate and titanium rather than rare earths or niobium.

Re-assayed historic drill results include 84m at 2.1% TREO including 22m at 4.7%, 114m at 2.3% TREO including 50m at 4.0%, and 122m at 1.2% TREO including 32m at 2.7%. Hole OA167 returned 106m at 1% TREO plus 28m at 0.5% Nb2O5. NdPr makes up 18–25% of TREO within high-grade internal zones. The company notes these are exploration results, not a Mineral Resource.

Drilling Program and Upcoming Catalysts

The re-assay work expanded the central target by more than 30%, identified a new northern REE zone, and showed mineralisation remains open at depth. About 8,000m of historic core has been re-assayed.

A 20,000m, four-rig drilling program is now underway, focused on initial resource definition. Upcoming catalysts include assay results, a maiden Mineral Resource, metallurgy, permitting and community work, followed by resource growth and a pre-feasibility study.

Corporate Position and Market Context

As of 16 October 2026, Oceana had about 250.9 million shares on issue, a market capitalisation of about A$71.5 million at A$0.285 per share, and about A$16.5 million in cash with no debt. The team is led by Managing Director Mick Wilson and Non-Executive Chair Russell Curtin.

Citing the IEA, the presentation notes that China accounts for about 91% of global magnet rare earth separation and refining, and that ex-China magnet REE demand is projected to grow by more than 50% by 2035.

Key Takeaways

Serra Negra is a large, historically under-explored carbonatite with rare earth and niobium potential.
Re-assays have expanded the central target and identified a new northern zone.
A 20,000m drilling program is working toward a maiden Mineral Resource.
Oceana is funded with about A$16.5 million cash and no debt.
