The Geological Service of Brazil (SGB) has identified concentrations of rare earth elements across the states of São Paulo, Paraná, and Santa Catarina [1].
These minerals are critical for the production of high-tech electronics, green energy infrastructure, and defense systems. Securing a domestic supply would reduce Brazil's reliance on foreign imports and strengthen its strategic position in the global technology supply chain [1, 2].
The findings are located within the Ribeira Belt, a geological region that spans the three identified states [1, 2]. This discovery is part of a broader geological study aimed at mapping the country's mineral wealth to support industrial growth [2].
Following the announcement on May 20, 2026 [1], the SGB is launching a dedicated research project to further evaluate the deposits [1]. This research phase is scheduled to continue through 2026-2027 [1].
The SGB said the project will assess whether these concentrations can be commercially mined. The agency intends to determine the exact volume and quality of the elements found in the Ribeira Belt to determine if the sites are viable for industrial extraction [2].
Rare earth elements are often difficult to mine and process due to their chemical properties. The upcoming research will focus on the technical feasibility of extracting these materials without causing undue environmental damage to the region [1].
Government officials said the initiative aligns with a national strategy to bolster the domestic tech sector. By identifying these resources, Brazil aims to integrate more deeply into the production of semiconductors, and electric vehicle components [2].
“Brazil identifies promising mineral concentrations in the Ribeira Belt.”
The discovery of rare earth elements in the Ribeira Belt represents a potential shift in Brazil's economic strategy toward high-value mineral exports and domestic tech manufacturing. Because these elements are essential for magnets and batteries, successful extraction could grant Brazil significant leverage in the global energy transition and reduce the current market dominance of a few key suppliers.
