Excellent in all respects’, Marval, O'Farrell & Mairal’s mining practice garners strong praise for its ‘unrivalled breadth of expertise across many practice areas’ and its ‘excellent client service’. The group’s ‘strong business mindset’ also finds favour, with key partner Leonardo Rodríguez highlighted as a ‘multifaceted lawyer who displays strong commitment to the client’s corporate aims’. Rodríguez recently advised Minera Hochschild Argentina on several issues, including exploration operations, environmental matters and the acquisition and maintenance of mining rights. Department head Luis Lucero is a ‘stand-out expert in his field’ and leads the firm’s representation of Oroplata, a wholly owned subsidiary of Goldcorp, on day-to-day matters relating to its Cerro Negro mine – a multibillion-dollar gold and silver operation. On the litigation front, Lucero represented Pachón (a wholly owned subsidiary of Glencore) in its $300m dispute with Minera Los Pelambres concerning a waste dump built by Minera Los Pelambres on Glencore’s property in Argentina. Senior associate Andrés Villarreal is also a key contact.

In a major coup, Allende & Brea hired high-profile mining specialist Florencia Heredia in 2017 – she was previously senior partner at Heredia, Lede Pizzurno & Terrel Abogados. The group also benefits from the experience of transactional energy and natural resources specialist Juan Martín Allende and project development and finance partner Marcos Patrón Costas. The firm covers all the bases in mining law, with strong skill sets in regulatory issues, project development, M&A and environmental matters. It is particularly prominent in the lithium space, where it acts for clients such as FMC and Galaxy Resources. Highly rated of counsel Carlos García Díaz left to become an independent practitioner.

Baker McKenzie’s mining group, which is well weighted between regulatory and transactional issues, is led by ‘very knowledgeable’ energy partner Adolfo Durañona. The firm’s enviable multi-jurisdictional expertise, combined with its growing profile in the lithium market, saw it recently add Qingdao Qianyun High-tech New Material Co. to its client roster. It also counts Vale, Trident Southern Explorations and Albemarle among its key clients. Recent mandates saw the team advise Albemarle on the development of Project Antofalla, a major lithium project in Catamarca Province. Roberto Grané is also routinely involved in mining matters.

Bruchou, Fernández Madero & Lombardi’s mining practice is led jointly by the ‘very dedicated’ Sebastián Vedoya and fellow sector specialist Sergio Arbeleche. The group acts for an impressive portfolio of major mining companies, with First Quantum Minerals and Yamana Gold featuring among the key names. Most notably, the firm provides ongoing advice to Barrick Gold, and its subsidiaries, on day-to-day matters in Argentina; among its recent work for the Canadian mining giant was advice on the $960m sale of a 50% stake in its Veladero mine to Shandong Gold Mining.

Knowledgeable and steeped in the industry’, Zaballa - Carchio Abogados attracts strong praise for its compact practice that is staffed by ‘extremely competent lawyers who understand the mining sector inside-out’. Its broad expertise ensures it is routinely involved in a diverse spread of matters, with robust experience in exploration, project development, M&A and regulation. Representative clients include McEwen Mining, Ling Cheng Mining and YPF. Name partner Hernán Zaballa enjoys a strong profile in the market and brings to bear a comprehensive record in both transactional and regulatory issues.

Beccar Varela’s mining group, led by Roberto Fortunati, routinely advises on a wide range of finance, corporate, tax and regulatory matters. Recent work includes acting for Southern Copper on regulatory and community matters regarding its exploration projects in Argentina. Other representative clients include Minera Don Nicolás, Saint Gobain Argentina and Esco Servicios Mineros. Senior associate Marcos Moreno Hueyo is also a key contact. Highly rated senior associate Diego Parravicini left for an in-house role at Pan American Silver.

Beretta Godoy houses a strong corporate mining practice which specialises in advising mining companies on corporate finance issues, M&A, joint ventures and tax issues – it also has significant administrative law capability. Among its recent matters, the firm assisted Barranca Sur Minera with its filings to acquire the final title for two coal mines. Project finance and arbitration specialist Federico Godoy and foreign investment partner Juan Sonada are the names to note.

Responsive, analytical and committed’, Mitrani Caballero & Ruiz Moreno Abogados is a new entrant to the mining ranking following the addition of a sizeable team from legacy mining heavyweight Heredia, Lede Pizzurno & Terrel Abogados. Among the new arrivals are former name partner Laura Lede Pizzurno (‘deep industry knowledge’), senior counsel María Paula Terrel and impressive senior associate Matias Olcese (‘provides practical and strategic solutions’). In a key highlight, the firm advised Toyota Tsusho Corporation on its A$292m strategic investment in lithium producer Orocobre to fund the expansion of the Olaroz Project.

In 2018, Alfaro-Abogados boosted its mining practice with the hire of a team from Quevedo Abogados, which included seasoned mining experts Ignacio Celorrio and Hernan Celorrio. Corporate, finance and regulatory law are all areas of expertise and the firm leverages its China desk to secure a significant volume of China-based clients.

Hope, Duggan & Silva provides ongoing advice to several mining companies on day-to-day operational matters, including advising on the acquisition of mining interests, rights of way issues, tax matters and joint venture agreements. Recent work includes assisting a mining company with a joint venture with a major domestic oil and gas producer for the supply of "frac" sand. Javier Zapiola and Hugo Vivot are the key contacts.

Traditionally better known for its oil and gas practice, Nicholson y Cano Abogados fields a capable mining department with broad experience in financings, exploration issues, project development, M&A and regulatory matters. Energy and natural resources partner Nicolás Perkins is recommended for his solid track record in transactional matters.

Among Zang, Bergel & Viñes Abogados’ recent work, key partner Amalia Sáenz teamed up with associate Nicanor Berola to advise Hoyada Mining on exploration and supplier contracts related to a copper and gold mining property in Catamarca. Other representative clients include Austral Gold and Shandong Gold Group.
