Emerging frontier under evaluation · Roraima
Complexo Barreira
An area exceeding 120,000 hectares at the mineral exploration stage. Published preliminary studies report occurrences of rare earths, including europium, neodymium, yttrium and ytterbium, along with other strategic elements. Current work focuses on expanding sampling and characterization, testing anomaly continuity, understanding mineralogy and evaluating a potential processing route.
Technical view: the published results do not yet amount to a formal mineral-resource or reserve estimate. Economic attractiveness will depend on scale, data representativeness, metallurgical recovery, infrastructure, permitting and feasibility studies.

Where capital can enter
Four investment theses.
From early-stage asset exposure to industrial businesses with recurring revenue.
01
Exploration backed by a strong geological thesis
Target portfolios supported by consistent data, a qualified technical team and milestone-based work programs reduce information asymmetry.
02
Unlocking advanced assets
Projects with defined resources may require metallurgy, permitting, infrastructure, economic studies and offtake agreements.
03
Processing and transformation
Separation, refining, battery materials, alloys and magnets capture more value and face higher technology barriers.
04
Circular economy and tailings
Reprocessing, remining and metal recovery can combine lower liabilities, existing infrastructure and new revenue.
Disciplined decisions
From opportunity to decision.
Mineral investment requires integrated technical, legal, environmental, social and commercial due diligence.
Evaluation path
01
Asset screening
Mineral title, location, commodity, project stage and available data.
02
Integrated due diligence
Geology, resources, process, permits, land rights, ESG and obligations.
