Florencia Heredia > Allende & Brea > BUENOS AIRES, Argentina > Lawyer Profile

The Allende & Brea mining practice is one of the firm’s oldest and most active departments and remains very much a “go-to” option for domestic and international mining entities seeking advice on complex-cross border mining M&A and financing matters. The practice is renowned for the breadth, depth and sophistication of its offering, which also includes regulatory, environmental, tax, financial and contractual matters. The team is currently at the forefront of matters in the lithium sector, but is also sought out for its extensive expertise in Argentina’s burgeoning metalliferous space, with copper-related projects proving a particularly active segment for the practice. The firm also works closely with authorities at national level to mitigate the impact of a high tax burden and hyper-inflation on the industry. With more than three-decades’ sector experience, practice head Florencia Heredia has become an influential industry leader and holds prominent positions with various Argentine and international industry bodies. Senior Agostina Martinez is a key name at associate level and focuses her practice on mining and foreign investment matters, with fellow senior – ESG, environmental and administrative practitioner, Martín Alejo Prieto – also prominent.

A formidable player in the mining sector, Allende & Brea has been working on growing its profile in the adjacent oil-and-gas sector, where it can leverage its full service capabilities, especially in the fields of tax, environmental law, contracts, M&A and financing in tightly regulated industries. Florencia Heredia, who is best known for her mining practice but also has experience across energy and the broader natural resources segment, leads the team; cross-border M&A financing partner Marcos Patron Costas, and associate Agostina Martinez (international oil-and-gas law, contracts and negotiations), are the other key contacts.

Allende & Brea takes an integrated approach to environmental law and is focused on helping clients manage the environmental, social and governance risks that impact long-term commercial sustainability. With extensive experience in the extractive and industrials sectors, the firm is well-versed in business and human rights issues; anti-corruption; corporate governance; green financing; climate change and renewable energy matters. Areas covered by the team include compliance with Argentine environmental legislation; environmental audits and due diligence; climate change disclosure and the representation of clients in individual and collective environmental litigation and environmental administrative proceedings. Administrative and environmental law specialist Maria Morena Del Rio co-leads the team alongside formidable mining and natural resources lawyer Florencia Heredia. Senior associate Martín Alejo Prieto, an expert in environmental compliance and individual and collective environmental disputes and litigation, leads the second line.

Allende & Brea advises power industry clients on transactional, regulatory, environmental, tax, financial and litigation matters and is especially active in the design and construction of natural gas, combined cycle and renewable energy power plants; where it advises on EPC contracts and project financing.
