Key Takeaways
  • • Brazilian asset manager MadCap launched the LTWSK Mining Fund with a US$200 million fundraising target focused on critical minerals investments in Brazil, managed in partnership with ORE Investments Ltda and supported by mining giant Vale and state development bank BNDES.
  • • The fund will allocate capital across 15–20 junior and medium-sized companies engaged in mineral research and critical mineral supply chains, with a minimum fundraising goal of R$1 billion (approximately US$175 million).
  • • Brazil controls approximately 95% of global niobium reserves and holds substantial deposits of rare earth elements and graphite, positioning the country as a strategic source for battery and advanced manufacturing supply chains.
  • • Serra Verde Group, Brazil's only producing rare earth miner, secured a separate US$565 million loan from the U.S. International Development Finance Corporation with an option for U.S. equity participation, signaling institutional capital's focus on de-risking critical mineral supply chains outside China.
  • • The fund reflects broader institutional appetite for critical minerals infrastructure, alongside competing vehicles like Kinterra Capital's US$565 million private equity fund dedicated to new mines and processing plants for battery supply.
Summary
Brazilian asset manager MadCap has launched the LTWSK Mining Fund to capitalize on growing demand for critical minerals essential to battery production and advanced manufacturing. The fund targets US$200 million in commitments, with a minimum fundraising threshold of R$1 billion (approximately US$175 million). The initiative combines private equity capital with strategic backing from Vale, one of the world's largest diversified mining companies, and BNDES, Brazil's state development bank. ORE Investments Ltda serves as the fund manager, positioning the vehicle as a professionally managed institutional offering.

The fund will deploy capital across 15–20 junior and medium-sized mineral exploration and development companies, targeting exposure to Brazil's critical mineral supply chains. This allocation strategy reflects institutional recognition that mid-stage mining companies often lack capital access despite holding valuable mineral rights. Brazil's mineral endowments provide substantial strategic value: the country controls approximately 95% of global niobium reserves—a critical input for steel alloys, superconductors, and advanced electronics—alongside significant deposits of rare earth elements and graphite, both essential for renewable energy and battery manufacturing.

The timing of the LTWSK fund launch reflects heightened geopolitical focus on securing critical mineral supplies outside China-dominated supply chains. This dynamic is underscored by concurrent developments: Serra Verde Group, Brazil's only producing rare earth miner, recently secured a US$565 million loan from the U.S. International Development Finance Corporation with a U.S. equity option, representing a 22% increase over the agency's initial approval. This de-risking strategy signals that Western governments and development finance institutions view Brazilian critical minerals as strategic infrastructure. The private equity market has responded accordingly, with competing funds including Kinterra Capital's US$565 million fund specifically dedicated to new mines and mineral processing plants for battery supply.

The LTWSK fund's positioning within Brazil's broader industrial policy framework further strengthens its strategic relevance. Brazil's government has prioritized critical minerals as a cornerstone of economic development and export competitiveness, particularly as global battery demand accelerates. By coupling private capital with BNDES support and Vale's operational expertise, the fund addresses both the capital constraints facing junior miners and the infrastructure gaps in mineral processing. For institutional investors, the vehicle offers structured exposure to critical minerals without direct project or exploration risk, through a curated portfolio of established and emerging mineral companies.
