Mining in Argentina

Allende & Brea

Allende & Brea stands out for its ‘knowledge of the mining industry, both from a local perspective and an understanding of what foreign mining investors are looking for’. The multidisciplinary mining practice is highly regarded for its ‘assertive and prudent way of handling the issues raised’ as well as ‘clarity in its approaches and responses’. A key specialism for the team, currently, is the lithium industry, in which segment the team not only advises on major transactions -such as Pluspetrol’s recent $85m acquisition of 300 lithium titles- but also advises foreign state agencies (such as the US Department of State and the Australian embassy) and investment agencies. Indeed, the practice has been at the forefront of the majority of significant transactions in the mining sector as a whole, representing Galaxy, for instance, on its $280m sale of assets in the provinces of Salta and Catamarca to Posco. Overall head of the energy and natural resources practice, renowned mining lawyer Florencia Heredia has ‘incomparable experience’; she focuses on natural resource and energy matters in general (and increasingly, arbitration), but her core focus remains mining, where she is a ‘very dependable source for information related to all aspects of a mining transaction’. Senior associate Agostina Martinez and associate Valentina Surraco are increasingly active in post-lithium, battery-minerals and rare earth issues. However, dual qualified associate Nahila Cortes left the firm in July 2021, as did former group co-head Juan Martín Allende, who retired from practice in March 2020 to focus on business and M&A consulting.

She works well leading a team of lawyers as needed for a specific transaction. She is very responsive and is a trusted advisor.’

We are very satisfied with the service we receive.
