The question for the magnets underneath AI hardware is no longer whether Brazil has the rock. It is who holds the claim and where the oxide gets separated. The Associated Press and Reporter Brasil reviewed every National Mining Agency record through June and found 2,727 rare earth exploration applications on file, 42 percent lodged by subsidiaries of foreign mining companies or firms with foreign ownership stakes, and 11 of the 20 largest filers foreign-backed, mostly Australian, US and Canadian [AP and Reporter Brasil, 2026-08-20]. More than 86 percent were filed in the past three years, including 268 in the first half of 2026. Brasilia’s answer, a bill conditioning foreign investment on transferring processing capacity into the country, has not moved. The Senate’s own record, compiled at 08:03 on August 20, still shows PL 2780/2024 carrying the status AGUARDANDO DESPACHO, awaiting dispatch, as it has since it arrived from the Camara on May 8 [Senado Federal, PL 2780/2024, apurado 2026-08-20].

What’s happening

• 2,727 rare earth exploration applications sit on file at the ANM through June, 42 percent foreign-linked. Australian companies lead with 695, nearly a third of those filed by Borborema Recursos Minerais, a subsidiary of Sydney-based Brazilian Rare Earths Pty Ltd. US companies rank second with 347, of which Alpha Minerals Brazil, controlled by Texas-based Rare Earth Americas Inc., accounts for 181 [AP and Reporter Brasil, 2026-08-20].
• Chinese companies had filed no rare earth mining applications in Brazil as of June. They are positioned by other routes: state-owned China Nonferrous Metal Mining Group bought Mineracao Taboca, Brazil’s largest tin producer, last year and has announced plans to study rare earth potential around its Amazon cassiterite mine, and Shenghe Resources signed a memorandum of understanding with WEG Mineracao and Fenrir do Brasil, which holds a Minas Gerais project [AP and Reporter Brasil, 2026-08-20].
• At least 25 percent of applications overlap with, or sit within 10 kilometres of, 283 protected areas and Indigenous territories, per the Energy Transition Observatory, a platform developed by Reporter Brasil that cross-references project geolocation against protected lands [AP and Reporter Brasil, 2026-08-20].

Brazil angle

The mechanism that matters for AI materials is the separation step, not the claim count. Lawmaker Ze Silva, author of the pending federal legislation on critical minerals and rare earths, framed it directly: “The challenge today is that China dominates processing and refining,” and under his proposal companies are welcome to invest but “must transfer technology to Brazil, including processing capacity” [AP and Reporter Brasil, 2026-08-20]. The bill would also create a national council to monitor significant foreign influence in the sector.

The procedural detail is the part the wires did not carry. Senate President Davi Alcolumbre announced on Friday August 14 that three government priorities, the minerals bill among them, had gone to committee, and speaking in Oiapoque, Amapa, on August 17 President Lula said, in translation from Portuguese, that Brazil will not let outsiders exploit its ores because the country wants the transformation done at home [Metropoles, 2026-08-17]. The Senate’s record does not yet reflect the referral. PL 2780/2024, the Ze Silva text that arrived from the Camara on May 8, has carried the status AGUARDANDO DESPACHO since that date and still carried it when the Senate’s page was compiled at 08:03 on August 20. A leader’s urgency request, RQS 506/2026, filed July 6, remains awaiting inclusion in the Ordem do Dia [Senado Federal, PL 2780/2024, apurado 2026-08-20]. The text that does have a rapporteur is a different vehicle: PL 4443/2025, by Senator Renan Calheiros, has sat with Senator Wilder Morais in the Infrastructure Committee since July 15 [Senado Federal, PL 4443/2025, apurado 2026-08-19]. An announcement is not a docket, and the bill Brasilia is talking about is not the bill that is moving. The 268 applications filed this half were filed under the rules that exist now, and pressure runs the other way too: the Ministry of Mines and Energy has discussed streamlining environmental licensing for strategic projects, and Senator Flavio Bolsonaro, challenging Lula in October’s election, has also proposed faster permitting [AP and Reporter Brasil, 2026-08-20].

US angle

Washington is now a shareholder, not just a lender. Serra Verde, the only rare earth producer in Brazil and the only one outside Asia able to supply all four magnetic elements (neodymium, praseodymium, dysprosium and terbium), secured a $565 million package from the US International Development Finance Corporation in February. In April, USA Rare Earth agreed to acquire it for about $2.8 billion, three months after Commerce announced up to $1.6 billion in support to USA Rare Earth. Commerce receives over 16 million shares, and the deal closed in June [AP and Reporter Brasil, 2026-08-20]. Separately, Aclara Resources, the Canadian firm whose Goias claims overlap the territory of Familia Magalhaes, an Afro-Brazilian community of some 30 families, secured $5 million in DFC project development financing last year and has opened a pilot processing plant in Louisiana. Aclara said the project initially overlapped the community’s territory but that “no mining activities will take place there.” Residents fear operations that could start as early as 2028 would affect local springs and wildlife [AP and Reporter Brasil, 2026-08-20]. That is schedule risk upstream of any offtake contract.

China angle

Zero filings is more informative than a filing surge would have been. Beijing already holds the separation and refining stage, precisely the leverage the Brazilian bill targets, and it does not need greenfield Brazilian claims to keep it. Buying into a producing Amazon tin operation with rare earth potential and signing an MOU with Brazilian industrial names is cheaper and less visible than competing in the claim queue. Leonardo Durans, a director at Brazil’s Trade Ministry overseeing rare earth policy, said the country will not take sides in the US and China dispute [AP and Reporter Brasil, 2026-08-20].

What it means

The attrition rate is the discipline here. Julio Nery of the Brazilian Mining Institute puts it at roughly 100 of every 1,000 rare earth prospects justifying drilling, and about two of those 100 becoming good projects [AP and Reporter Brasil, 2026-08-20]. Applied to 268 applications in half a year, the claim rush is option-buying, not incoming supply. The desk’s SOV50 read carries rare earths at an HHI of 0.52 against China at roughly 70 percent of production, with the price-style index at 121.8, off 0.16 percent on the week and up 14.6 percent year to date, while SDX, the alternative-supply side of the same question, sits at 98.3, off 1.01 percent on the week and down 3.9 percent year to date (index file updated 2026-08-14). Concentration is being priced. Diversification is not yet being paid for. A statute conditioning foreign access on domestic separation would, if enacted, slow oxide out of Brazil near term and change what SDX actually tracks over a longer horizon. As of this week it is not enacted.

What to watch

• Whether PL 2780/2024 finally receives a formal despacho to a named committee, or whether the Calheiros vehicle PL 4443/2025 becomes the text that carries the processing condition. Wilder Morais’s report in the Infrastructure Committee is the signal to watch.
• Whether any Chinese rare earth application appears in ANM records after the June cutoff, and whether the CNMC study around the Taboca cassiterite mine converts into a filing.
• Aclara’s Goias timeline against its stated 2028 start, and whether the Familia Magalhaes overlap becomes a licensing condition rather than a company statement.
