Mining in Argentina

Allende & Brea

Allende & Brea stands out for its ‘profound knowledge of the industry’, with sources asserting that ‘few other firms have big enough teams, or the necessary experience, to advise mining companies properly’. The multidisciplinary department is comprised of lawyers with experience in a range of regulatory, environmental, tax and transactional matters and is routinely involved in the largest mining matters to involve Argentina. A strong performer in the lithium market -currently the most active sub-sector in Argentina’s mining industry- the group counts Livent, Rio Tinto and Galaxy Resources among its key clients. Additionally, the group is consistently called upon by outside state and investment agencies to provide strategic advice and jurisdictional guidance. High-profile department head Florencia Heredia is ‘uniquely knowledgeable in mining’ and is widely recognised for her premier experience advising companies and financial institutions in mining transactions. Heredia, senior associate Agostina Martinez and associate Valentina Surraco are increasingly active in post-lithium, battery-minerals and rare earth issues; while dual qualified (Buenos Aires and New York) associate Nahila Cortes is also noted for her focus on both energy and mining work. Former group co-head Juan Martín Allende recently retired from practice to focus on business and M&A consulting.

Practice head(s):

Florencia Heredia


The environmental and regulatory issues, diverse jurisdictions and varied stakeholders involved in the mining sector in Argentina mean that the team’s experience is fundamental. Few other firms have big enough teams, or the necessary experience, to advise mining companies properly.’

They stand out fundamentally for their ability to prioritise.’

They have profound knowledge of the industry and the various jurisdictions, and the ability to connect the reality on the ground with the needs and expectations of international investors and mining companies.’

I don’t think there is another lawyer in the mining and energy sector in Argentina with the level of professionalism, neutrality and transparency that is shown by Florencia Heredia and her team. This opinion is shared by other colleagues who have worked with Allende & Brea for even longer than I have.

Florencia Heredia knows what is happening in Argentina and Latin America, how to understand it, and how it compares worldwide. She is uniquely knowledgeable in mining, and can provide a perspective that no other lawyer can.

The team excels across the full range of mining issues, including planning and mining rights, environmental matters, project construction, joint ventures and finance deals. The group also benefits from its ability to lean on the firm’s market-leading corporate practice to advise on complex, multi-jurisdictional mining transactions, such as its advice to South Korea-based POSCO on its $280m acquisition of lithium brines-related mining rights from Galaxy Resources. Additionally, it packs a punch in contentious work, with strong expertise in commercial and regulatory litigation. Widely lauded as a market leader, department head Luis Lucero ‘simply towers above the competition’ on the back of his involvement in many of Argentina’s largest mining projects — he led the POSCO deal. Dedicated mining partner Leonardo Rodríguez is also highlighted as an ‘exceptional lawyer’ and specialises in commercial law and litigation. Associate María Mercedes Rudolph, who ‘excels in company and corporate law’, and senior associate Andrés Villarreal are also recommended.

Practice head(s):

Luis Lucero


Marval’s mining team is second-to-none. Vast resources coupled with peerless experience and commitment make this the outstanding mining practice in Argentina.’

They have excellent delivery: quick, precise and without any errors. It is a multidisciplinary team, which reassures us that we can trust them to advise on any kind of matter.’

The head of the practice is Luis Lucero. He is the go-to person for all matters, especially those that, in light of their complexity, require an innovative approach. Having worked with most of his peers, I would not hesitate to reach out to Luis and his team in future. He simply towers above the competition.

In spite of clearly being the leading practitioner in the field,  Luis Lucero is happy to make himself available whenever his sound advice, clear judgement and legal and industry knowledge are required. No matter is too trivial, or too complex for him. He also makes sure the issue gets resolved, taking a personal interest in the outcome and deliverable required.’

Leonardo Rodriguez is an exceptional lawyer with experience in many practices but a particular focus and specialisation in the mining industry, which gives him an advantage.’

Leonardo Rodriguez demonstrates excellent knowledge and skill sets in his realm of expertise.’

Baker McKenzie

Baker McKenzie’s ‘high-quality service’ strikes the right note with sources, who highlight its lawyers’ ‘extensive knowledge’ and ‘firmness and accuracy in their opinions’. The practice is adept across a wide scope of regulatory, transactional and contentious matters for a diverse mix of mining companies, including recent work for clients operating in the lithium, gold and potash sub-sectors, among others. The group also benefits from its ability to draw upon the wider international firm’s globally recognised mining department. Managing partner Adolfo Durañona is highly regarded for his experience in mining transactions, including commercial agreements, projects and M&A. Durañona jointly leads the practice together with energy and TMT partner Roberto Grané and Ezequiel Artola, who advises across the full range of energy and natural resources transactions. Associate Tomás Trusso provides capable support.


They provide a high-quality service, respond on time and always with an excellent answer. They are always available to resolve our concerns and to coordinate operations on the ground.’

Baker McKenzie has been advising us on mining issues for several years and the team differentiates itself through its extensive knowledge of applicable legislation, as well as related background information.’

Since we do not have internal lawyers in Argentina, we have to place a lot of trust in the internal lawyers of our headquarters, who do not know the specific local laws. Baker McKenzie’s firmness and accuracy in their opinions make the internal legal team feel secure in decision making.’

The partner in charge of our account is Adolfo Durañona and the senior lawyer is Tomás Trusso. The team advises us on strategic and operational issues with ease, and we have total confidence in their advice on day-to-day matters as well as specific questions that require a closer look.’

In addition to their knowledge of specific areas, the lawyers at Baker McKenzie stand out for their availability and the speed of their responses, which we haven’t found at other firms. Adolfo Durañona, Ezequiel Artola and Tomás Trusso particularly stand out.
