• Brazil rejects exclusive critical minerals agreements, opting for an open multi-partner strategy to attract broad international competition and investment.
• The U.S. Project Vault initiative offers $10 billion for critical mineral supply chains, but Brazil chooses to engage multiple countries, including the EU and India.
• Brazil's approach aims to leverage global demand to build domestic processing capacity and R&D while maintaining geopolitical flexibility in the minerals sector.

Brazil does not intend to sign exclusive agreements with any country to develop its critical minerals, choosing instead to maintain an open, multi-partner approach, according to a BNAmericas report (opens in a new tab).

The announcement comes as the United States advances “Project Vault,” a strategic initiative led by the Export-Import Bank of the United States (EXIM) aimed at strengthening U.S. critical mineral supply chains. EXIM’s board has approved up to $10 billion in direct lending authority for the initiative, described as more than twice the size of the bank’s previous largest single financing package. The program seeks to reduce U.S. exposure to supply disruptions, expand domestic production and processing, and reinforce long-term supply resilience. As part of that effort, U.S. officials have held discussions with multiple governments, including Brazil’s, regarding closer cooperation in critical minerals and rare earth supply chains.

However, according to an unnamed Brazilian government representative interviewed by BNAmericas, Brasília has no intention of entering into exclusive development agreements with any single country. Instead, Brazil’s strategy is to attract broad international participation and allow market competition to determine outcomes.

José Carlos Martins, (opens in a new tab) mining consultant and partner at Neelix Consulting, described the policy as economically rational. In his view, Brazil should leverage heightened global demand to stimulate domestic processing capacity, expand research and development, and encourage technological innovation tied to its mineral resources.

Brazil’s position comes amid increasing international interest in its mineral sector. European Union representatives have expressed interest ininvesting in Brazilian critical mineral projects. President LuizInácio Lula da Silva is also expected to visit India in the coming weeks to discuss potential cooperation in the sector.

Notably, Brazil’s rejection of exclusivity is not presented as a rebuff of U.S. engagement. Lula is expected to address the topic during a planned visit to the United States. Meanwhile, U.S. financing has already supported Brazilian rare earth development: Mineração Serra Verde, controlled by Denham Capital, secured $565 million from the U.S. International Development Finance Corporation (DFC) to expand its Pela Ema rare earth project in Goiás state.

For Washington and Brussels, the signal is clear: Brazil intends to remain commercially open and geopolitically flexible in the evolving critical minerals landscape.
