Allende & Brea advises on a wide range of legal and regulatory matters linked to mining projects in Argentina, with a particular focus on the lithium and copper sectors. The team provides support across all stages of project development, including project financing – often involving sustainability-linked loans – and the acquisition of mining rights by international investors. The firm guides clients through Argentina’s complex regulatory landscape, advising on mining investment laws, stability tax regimes, and environmental compliance. Its corporate expertise extends to M&A, corporate governance, and due diligence processes for mining companies operating in the country. Practice head Florencia Heredia, praised for her ‘industry knowledge and experience’, advises mining companies and lenders on some of the largest project financings in the country. She is supported by a strong roster of senior associates, including Agostina Martinez and Maria Milagros Pieroni, who provide support in the acquisition of mining rights and shares in local companies, Martín Prieto, who advises on environmental regulatory and permitting matters, and Lucrecia Re and Vanesa Fernández, who counsel clients on competitive public bids and contracts.
