Mining companies, investors and financial institutions trust Mattos Filho’s ‘customer-focused approach’ and ’technical quality’ in transactional matters, ranging from cross-border M&A and project financing to joint ventures, investments, royalties transactions and commercial agreements. The collaborative team also handles ESG-related and regulatory matters, contributes to policy-making, and is particularly active in critical minerals matters, notably involving lithium. Brasília-based Adriano Drummond Trindade, ‘knowledgeable’ of mineral policy and regulations, advises on project development, M&A, financings, as well as contractual and ESG-related matters. Bernardo Môcho, based in São Paulo, and Rômulo Sampaio, in Rio de Janeiro, frequently support the practice in project financing and environmental matters, respectively.
