Highlights

• Brazil controls 23% of global rare earth reserves but currently produces only 1% of global market supply.
• Potential for strategic rare earth mining exists, but complex challenges include:
  • Environmental preservation
  • Land conflicts
  • Responsible development
• Brazil could emerge as a key rare earth partner for Western markets, particularly in:
  • EV (Electric Vehicle) industry
  • Defense industry

Brazil does indeed hold significant geological weight: about 23% of global rare earth reserves, per the U.S. Geological Survey’s 2025 Mineral Commodity Summaries. Production, however, is barely 1% of the world market—a sobering reminder that reserves do not equal supply. The cited 187 pending mining applications in INCRA settlement zones also checks out, flagged by Brazil’s own Mining Observatory. And yes, Bahia has already signed an MoU with Borborema Mineração for oxide processing, with investment estimates of roughly $650 million.

The Tree vs. the Trenches

The centerpiece anecdote—a 600-year-old Brazilwood tree threatened by nearby exploration—rings true as a symbol of the ecological stakes. Brazilwood is endangered, historically overharvested, and culturally iconic. However, highlighting a single tree as emblematic of the entire rare earth mining wave leans heavily on narrative framing. It risks overshadowing more systemic issues like water use, tailings management, and the displacement of smallholders.

When Advocacy Shapes the Lens

Much of a recent assessment via Mongabay (opens in a new tab) adopts the voice of activist groups such as MST and CPT. Their concerns about land conflicts, violence, and community disruption are not unfounded—Brazil’s mining history is riddled with such patterns. Still, the article leaves little space for Brazil’s countervailing narrative: national economic goals, supply-chain diversification away from China, or the fact that ionic clay deposits could be strategically vital for Western EV and defense markets. The absence of corporate responses beyond Borborema Mineração’s MoU weakens the balance.

Why Investors Should Care

The accurate core is this: Brazil is a sleeping giant in rare earths, with ionic clay deposits that, if unlocked responsibly, could shift market share away from China. Rare Earth Exchanges (REEx) has reported, for example, on the potential of Brazilian Rare Earths (opens in a new tab) and others.  But speculation about “predatory” expansion assumes worst-case outcomes without weighing regulatory mechanisms like Agência Nacional de Mineração  (ANM) licensing or National Institute for Colonization and Agrarian Reform (INCRA) oversight. Investors should note: these conflicts are not theoretical—they could slow permitting timelines, inflate costs, and ignite ESG-driven pushback. Brazil may emerge as a major player, but the road will be uneven, contested, and noisy.

Bottom Line

The reporting is factually anchored but selectively amplified. The environmental and social risks are real; the portrayal of Brazil as on the cusp of ecological ruin is more speculative. What’s missing is a sober assessment of Brazil’s potential to become the West’s key rare earth partner—and the high-stakes balancing act between conservation and strategic minerals.
