US–Brazil critical minerals chain: project economics and policy notes for mine planners
Reviewed by Joe Ashwell

30 Second Briefing
US-backed moves to build a Brazilian critical minerals chain are accelerating, with American investment already above $600 million and a non-binding agreement in Goiás covering rare earth mining, separation, metal alloys and permanent magnets. USA Rare Earth’s $2.8‑billion acquisition of the Serra Verde operation, producing mixed rare earth carbonate at Pela Ema, and St George Mining’s study of a 2‑billion‑real processing and separation centre in Minas Gerais signal concrete downstream ambitions. New Brazilian legislation creates a National Council for the Industrialisation of Critical and Strategic Minerals and offers tax credits of up to 20% for processing and urban-mining spend from 2030–2034, tightening state oversight of strategic assets.
Technical Brief
- The company notes such large-scale MREC-to-separated-product technology is currently unavailable commercially outside Asia.
- Serra Verde is described as Brazil’s only commercial-scale rare earth producer, elevating its strategic sensitivity.
- Brazil’s new National Council for the Industrialisation of Critical and Strategic Minerals can veto control changes in “strategic” mineral-rights holders.
- The same law enables tax credits up to 20% for processing, transformation and urban-mining spend, capped at 1 billion reais annually.
- Tax incentives apply only between 2030–2034 and require prior approval from the National Council.
- Rare Earths Americas is evaluating Brazilian separation and potential magnet manufacturing, contingent on infrastructure, energy pricing, capital access and regulatory certainty.
- A US–Goiás memorandum explicitly spans mining, separation, alloy production and permanent magnet manufacturing within the state.
- For other jurisdictions, Brazil’s model couples tighter state approval of strategic assets with targeted, time-bound processing tax credits.
Our Take
The roughly $2.8 billion USA Rare Earth move on Serra Verde puts Brazil’s rare earths in the same strategic conversation as MP Materials and Lynas, which feature in our other rare earth coverage, signalling a push to build non‑Chinese magnet supply spanning the Americas and Australia.
The proposed 2‑billion‑real processing hub in Minas Gerais, combined with Brazil’s capped 20% tax credits, suggests Brazil is targeting the same ‘friend‑shoring’ window that recent US copper and critical minerals pieces in our database link to AI‑driven demand growth and Pentagon/White House supply‑chain concerns.
