Oceana Metals (ASX: OCN) — Acquires Serra Negra Rare Earths Project in Brazil and Raises A$20 Million
On 28 April 2026, Oceana Metals Limited (ASX: OCN) announced the acquisition of 100% of the Serra Negra Rare Earth and Niobium Project in Minas Gerais, Brazil, together with a concurrent A$20 million institutional placement. Serra Negra is a district-scale carbonatite complex approximately 10 km in diameter — described by the company as the largest and least-studied alkaline-carbonatite complex in Brazil's Alto Paranaíba Igneous Province (APIP), the same geological district that hosts the world-class Araxá niobium-rare earth operations (CBMM, ASX: SGQ) and Catalão complex. Due diligence sampling of historical drill core returned laboratory assays averaging 3.4% TREO across 17 grab samples in one hole (LG26, range 0.39–8.4% TREO) and 4.4% TREO across 5 grab samples in another (LG42, range 2.9–6.1% TREO). No Mineral Resource has been reported for the project. The acquisition is led by a management team with prior involvement in Bellevue Gold (ASX 200) and Firefly Metals (ASX 300), with corporate consultants Steve Parsons and Michael Naylor as major shareholders.

Serra Negra Project — Location, Geology and Due Diligence Results
The Serra Negra Project is located near Patrocínio in Minas Gerais State, Brazil — within 20 km of rail, road, power, water, and workforce infrastructure. The project sits within the Alto Paranaíba Igneous Province (APIP), one of the world's most concentrated clusters of carbonatite complexes, which includes the Araxá complex (CBMM's world-class niobium operations; ASX-listed St George Mining's 70.9Mt @ 4.06% TREO rare earth resource) and the Catalão complex.
At approximately 10 km in diameter, Serra Negra is described as the largest carbonatite complex in the APIP. The project has been held in private hands for over 10 years and has not been the subject of systematic modern exploration.
As part of acquisition due diligence, Oceana independently sampled historical drill core with results analysed by ALS using four-acid digestion ICP-AES (with REE over-limit samples analysed by ICP-MS):
- Hole LG26: 17 grab core samples averaged 3.4% TREO (range 0.39–8.4% TREO)
- Hole LG42: 5 grab core samples averaged 4.4% TREO (range 2.9–6.1% TREO)
- Hole LG32: 9 grab core samples averaged 1.43% TREO (range 0.7–3.0% TREO)
Portable XRF (pXRF) analysis of historical drill holes demonstrated up to 100-metre-thick mineralised REE zones in laterally continuous weathered carbonatite. Mineralisation remains open in multiple directions including at end-of-hole. Multiple large-scale REE targets have been defined, with emerging and conceptual target areas not yet sampled for REE.
An emerging niobium (Nb₂O₅) target has also been identified, with independent laboratory assays returning up to 1.64% Nb₂O₅ from grab samples in carbonatite units adjacent to the main REE zones.
A$20 Million Placement and Capital Structure
The concurrent placement raises approximately A$20 million (before costs) through the issue of up to ~55.6 million new shares at A$0.36 per share — a 17.2% discount to the last closing price of A$0.435 on 12 February 2026 (the company's shares have been in voluntary suspension since that date following receipt of a price and volume query from the ASX). Directors have committed A$550,000 to the placement, subject to shareholder approval.
Tranche 1 (~A$7.4 million) utilises existing placement capacity under ASX Listing Rules 7.1 and 7.1A, with settlement on 4 May 2026. Tranche 2 (~A$12.6 million) is subject to shareholder approval at an EGM expected in early July 2026.

Exploration Plan — Near-Term Re-Assaying to Drilling-Led Resource Definition
The company has outlined an execution-led exploration program with the following phases:
Q2–Q3 2026 — Confirmation sampling: Re-logging, sampling and assaying of ~8,000 metres of historical drill core to validate results and establish geological and geochemical controls.
Q3–Q4 2026 — Drilling: Targeted drilling of up to ~20,000 metres to define scale and continuity of the central REE target and test extensions and priority exploration targets. Initial Phase 1 drilling at 100–200 metre spacing targeting an Inferred Resource, with resource upgrade drilling at 50 metre spacing to follow.
Q3 2026 onwards — Geophysics: District-scale surveys to refine intrusive architecture, identify controls on mineralisation, and generate new REE targets.
Q4 2026 onwards — Metallurgy: Early-stage metallurgical testwork to assess processing pathways.
2027 — Resource estimation: Integration of datasets to support an initial Mineral Resource Estimate, with future upgrades subject to exploration success and data density.
Market Context
OCN closed at $0.605 on the announcement day, up +39.1% from a previous close of $0.435 (the last traded price prior to voluntary suspension on 12 February 2026), with an intraday high of $0.730. The 52-week range spans $0.024 to $0.730. The stock resumed trading after approximately 10 weeks in voluntary suspension. The announcement comes amid heightened global interest in Western-aligned rare earth supply chains, with China's dominance in REE production and processing driving government and corporate efforts to secure alternative sources. Brazil has been attracting increased rare earth investment, including USA Rare Earth's US$2.8 billion acquisition of Serra Verde Group announced in April 2026.
Risks & Considerations
Pre-resource stage: No Mineral Resource has been reported for Serra Negra. The due diligence results are based on grab samples from historical drill core, not systematic sampling. Grab samples are selective by nature and may not be representative of the deposit as a whole. There is no certainty that exploration will result in a Mineral Resource.
Historical data reliance: The project relies on historical drilling, lithological logs, and core that was drilled and stored by previous operators. The quality, completeness, and reliability of this historical data has not been independently verified beyond the due diligence sampling program.
Sovereign and permitting risk: The project is located in Brazil. While Minas Gerais is an established mining jurisdiction, permitting timelines, environmental requirements, and community engagement processes may introduce delays or complications. The project will require environmental baseline studies and regulatory approvals before development can proceed.
Dilution: The placement and acquisition consideration shares increase the share count from 167.8 million to 245.3 million — a ~46% increase. Tranche 2 (~A$12.6 million) remains subject to shareholder approval at an EGM. Further capital raisings may be required as exploration advances.
Voluntary suspension context: OCN shares were in voluntary suspension since 12 February 2026 following a price and volume query from the ASX. The stock had moved from $0.024 to $0.435 over the preceding months prior to suspension.
Single-asset concentration: Following the acquisition, OCN's value proposition is substantially concentrated in the Serra Negra Project, which is at an early exploration stage with no resource, no metallurgical testwork, and no economic studies completed.
Milestone payments and royalty: The vendor retains a 2.5% NSR royalty on all payable commodities, plus milestone cash payments of US$750,000 (on initial JORC Resource) and US$1.5 million (on ≥100Mt @ 4% TREO resource). These represent ongoing obligations that reduce the project's net economic interest to OCN.
Scandium market comparisons are not applicable: While the project is in a carbonatite complex, the REE and niobium market dynamics, pricing, and end-use applications differ substantially from scandium, nickel-cobalt, or other commodity comparisons. No economic study has been conducted for Serra Negra.

Summary
Oceana Metals announced the acquisition of the Serra Negra rare earth and niobium project in Minas Gerais, Brazil — a carbonatite complex approximately 10 km in diameter located in the same geological district as the world-class Araxá and Catalão complexes. The acquisition is funded by a concurrent A$20 million institutional placement at A$0.36 per share, with total consideration comprising US$2.95 million cash, 20 million OCN shares, milestone payments of up to US$2.25 million, and a 2.5% NSR royalty. The announcement coincided with a +39.1% move to $0.605 on the first day of trading following approximately 10 weeks in voluntary suspension. Due diligence sampling of historical core returned REE grades averaging 3.4–4.4% TREO from grab samples, with pXRF indicating up to 100-metre-thick mineralised zones in laterally continuous weathered carbonatite. The company plans to re-assay ~8,000 metres of historical core and drill up to ~20,000 metres targeting an initial Mineral Resource Estimate in 2027. No Mineral Resource currently exists for the project.
