Brazil rare earths Rio Grande Rise ambitions intensify as its UN claim advances. Brazil rare earths Rio Grande Rise could unlock a vast offshore resource. Brazil rare earths Rio Grande Rise also reinforces the nation’s Blue Amazon strategy. Officials aim to expand rights over mining, energy, and fisheries.
Offshore scope and resource potential
The Rio Grande Rise spans about 500,000km² in the South Atlantic. It sits roughly 1,200km off Rio Grande do Sul. Studies flag rare earths alongside red clays, basalt, and manganese crusts. These deposits include NdPr, Dy, Tb, and other magnet metals. Therefore, Brazil sees high-value opportunities for batteries and clean tech.
Brazil already holds significant rare earth reserves onshore. The claim could extend access into a new marine province. Meanwhile, UNCLOS procedures guide shelf limits and sovereign rights. If approved, Brazil gains stronger control over exploration. That would accelerate investment screening and early baseline surveys.
Strategic stakes for supply chains and energy
The bid aligns with Brazil’s Blue Amazon development plan. The plan spans offshore minerals, renewables, and hydrocarbons. Global rare earth reserves reached 130mn tonnes in 2023. Brazil holds about 16%, behind Vietnam and tied with China. As a result, diversified offshore feed could bolster security of supply.
Downstream industries need stable magnet and catalyst inputs. EVs, wind turbines, and electronics drive that demand. However, environmental safeguards and data transparency remain vital. Therefore, Brazil must balance exploration with marine stewardship.
The Metalnomist Commentary
This seabed push is about leverage, not near-term output. The value lies in optionality during tight rare earth cycles. Watch UN milestones, baseline ecology work, and any pilot sampling plans.
