Germany Courts Brazil’s Critical Minerals at Belo Horizonte Summit

The 11th Brazil-Germany Mining Conference convenes tomorrow at Exposibram 2026 in Belo Horizonte, and it is the most visible signal yet that global capital is repositioning toward Brazil as a critical minerals anchor.

The conference is a surface event that reflects something deeper. Europe’s post-Ukraine rethink of single-supplier dependencies, the lesson applied so painfully to Russian gas, is now being applied to raw materials. Germany is not arriving in Minas Gerais out of curiosity. It is arriving with an industrial model exposed across automotive, machinery, and chemicals, and with a policy mandate from the EU Critical Raw Materials Act to secure diversified supply before the next bottleneck hits.

Here is what the sprint for Brazilian minerals is actually about: what Brazil holds, why this moment in the energy transition is producing urgency, what Germany and other partners are building in practice, and what could slow the build-out even as billions flow in.

Brazil’s geology gives global buyers something almost no other country can offer

Start with the number that explains everything else. Brazil holds approximately 66.6% of the world’s niobium reserves and produces roughly 92.9% of global supply, almost entirely from CBMM’s operation at Araxá in Minas Gerais. Niobium is the alloying metal that makes high-strength steel possible, a material the energy transition cannot function without. That kind of concentration in a single democratic jurisdiction is not merely important. It is system-critical.

Brazil’s niobium reserves are concentrated almost entirely within a single geological formation in Minas Gerais, a structural feature that explains both the extraordinary production dominance and the strategic exposure any global buyer faces when sourcing the metal from a single district.

But niobium is only the headline. Brazil also holds approximately 25.5% of global graphite reserves, rare earth reserves of roughly 21 million tons (second only to China), and has risen to become a top-five global lithium producer, driven by hard-rock projects ramping up across Minas Gerais. The 2026 investor guide from Brazil’s Mines and Energy Ministry lists active or planned projects spanning lithium, graphite, nickel, copper, titanium, vanadium, niobium, and rare earths.

This is a multi-commodity portfolio, not a single-mineral bet. And the reserve picture is almost certainly an undercount.

The 75% of Brazil that has not been explored yet

According to Ibram, Brazil’s mining institute, the country holds approximately 10% of the world’s reserves of key critical minerals, despite only about 25% of its territory having been geologically mapped in detail. That mapping gap is both a risk and the reason early movers are in a hurry. Three-quarters of the country’s geological potential remains unquantified.

For global buyers, this reframes the proposition entirely. Securing a position in Brazil now is a fundamentally different calculation than entering a mature, well-mapped jurisdiction. The upside is still being discovered, and the partners who build relationships before the full reserve picture emerges will hold a structural advantage over those who wait.

Why Germany is here now, and why the timing is not a coincidence

The causal chain runs directly from Russia’s gas infrastructure to Belo Horizonte. Germany learned what single-supplier dependency costs when Russian gas was weaponised. That lesson, applied first to energy, is now being applied to the raw materials that underpin German manufacturing.

Germany’s exposure is specific and concentrated. Its automotive sector needs lithium, nickel, and rare earths for electric vehicles. Its machinery sector needs high-strength steel alloys that depend on niobium. Its chemical industry needs graphite and specialty metals. These are not abstract geopolitical concerns. They are supply-line vulnerabilities that run through every factory in Baden-Württemberg and Bavaria.

The EU Critical Raw Materials Act provides the regulatory mandate to act, requiring member states to diversify sourcing and reduce dependency on any single supplier. Brazil sits at the intersection of that mandate: democratic governance, major reserves across Europe’s priority minerals list, and an existing mining and metallurgical base that means partnerships start from operational reality, not greenfield speculation.

The EU Critical Raw Materials Act provides the regulatory mandate to act, requiring member states to diversify sourcing and reduce dependency on any single supplier; the legislation sets binding targets for domestic extraction, processing, and recycling that make partnerships with jurisdictions like Brazil a structural requirement rather than a commercial preference.

Bruno Vath Zarpellon, Executive Director of Business Development at AHK São Paulo, has emphasised that mining plays a strategic role in energy transition and industrial transformation.

This week’s conference is not a cold start. AHK São Paulo’s Competence Center for Mining and Mineral Resources has built a dedicated sector presence in Brazilian mining over the past decade, connecting companies and institutions across the two countries. The conference themes reflect where that decade of relationship-building is heading:

• Mineral resource supply for the energy transition and downstream integration
• Digital transformation and automation across mining operations
• Building supply chains that are both secure and resistant to disruption

For the reader tracking supply chain geopolitics, the German presence in Belo Horizonte is the clearest available signal that Europe has concluded diversification away from China is not optional, and Brazil is one of the very few jurisdictions large enough to meaningfully absorb that demand.

What the Brazil-Germany cooperation model actually looks like in practice

The partnership being negotiated in Belo Horizonte is not a purchase agreement. It is a three-layer industrial relationship, and each layer tells you something about where battery and magnet supply chains will be located in the 2030s.

The competitive dynamics shaping critical mineral supply chains extend well beyond bilateral agreements; processing concentration in China, export restriction precedents set across multiple commodities, and OECD buyer behaviour are all feeding into the terms on which Brazil is now negotiating partnerships.

1. Technology and digitalisation: German firms bring mining automation, digital process control, environmental monitoring, and precision engineering. Brazilian operators are seeking these capabilities to cut costs, improve safety, and reduce environmental impact. Industrial digitalisation is explicitly listed as a key theme of the 2026 conference.
2. ESG and sustainability standards: European buyers face regulatory and consumer pressure to prove imported minerals meet stringent environmental and social standards. That pressure incentivises co-developed certification frameworks rather than purely transactional purchase arrangements. Both sides benefit: Germany gets traceable supply, Brazil gets access to premium markets.
3. Local value addition and downstream capacity: Brazilian policy is explicitly pushing for refining, processing, and potentially battery or magnet component manufacturing to happen on Brazilian soil.

The third layer is where the real negotiation is playing out.

The battle over where processing happens

Brazil’s critical minerals strategy and the 2026 Mines and Energy Ministry investor guide explicitly promote downstream development. The goal is to avoid a repeat of past commodity cycles where raw materials left Brazil and the processing value was captured offshore.

The alignment of interests is genuine, if conditional. Germany and other partners benefit from traceable, processed supply close to source, which simplifies compliance with the EU Critical Raw Materials Act. Brazil benefits from industrial development, jobs, and a structural move up the value chain. Whether that alignment holds under commercial pressure, when margins tighten and timelines slip, is the open question that will define the next decade of this relationship.

A $76.9 billion investment wave is building, but so are the obstacles

The financial scale is no longer speculative.

According to Ibram forecasts, total mining investment in Brazil from 2026 to 2030 is projected at approximately $76.9 billion, with roughly $21.3 billion (approximately 28%) directed specifically toward critical minerals including lithium, nickel, niobium, and rare earths.

That critical minerals figure represents a sharp increase relative to previous investment cycles and tells you that institutional capital has already moved. The question is no longer whether Brazil will be central to global critical mineral supply chains. The question is how quickly, and on whose terms.

Policy is catching up to the commercial reality. A critical minerals bill approved by Brazil’s lower house in May 2026 aims to strengthen national control over strategic deposits while signalling openness to foreign capital under defined regulatory conditions. For long-horizon investors, the combination of legislative clarity and investment scale is the signal that matters.

But the path is not frictionless. Four structural constraints will shape how quickly geological potential converts into real supply:

• Geological mapping gap: Only approximately 25% of territory has been systematically mapped, creating uncertainty even as it implies upside
• ESG and community risks: Deforestation, water use, tailings safety, and impacts on Indigenous and traditional communities remain central concerns at domestic and international levels
• Regulatory and infrastructure bottlenecks: Licensing complexity and infrastructure gaps can slow project timelines even as demand pressures accelerate abroad
• Equitable benefit distribution: Brazil faces the strategic challenge of expanding production fast enough to secure its place in supply chains while ensuring jobs, industrial development, and fiscal revenues are broadly shared

None of these constraints are disqualifying. All of them are real, and dismissing them would misread the timeline.

What this week’s conference signals about where Brazil sits in the global supply chain race

The 11th Brazil-Germany Mining Conference is not a diplomatic courtesy. It is a marker of Brazil’s structural transition from a conventional mining jurisdiction to a globally contested critical minerals hub, with partner nations across multiple continents now moving to establish footholds in the country’s mineral sector. Three variables will determine whether Brazil fully captures the opportunity: the pace of geological mapping across the 75% of territory that remains unquantified, the speed and quality of regulatory reform following the May 2026 critical minerals bill, and the success of downstream value-addition policy in keeping processing onshore. Brazil’s position on both the EU and U.S. priority minerals lists ensures that OECD partner interest will persist regardless of short-term political cycles.

The decisions made in partnerships struck this year and next will heavily shape who controls mid-2030s critical mineral supply chains. Brazil is no longer a peripheral player in that contest. It is one of a handful of jurisdictions capable of materially reshaping how the world sources the minerals the energy transition requires, and the countries building relationships now are positioning for supply chain influence that will persist for decades.
