Marval O’Farrell Mairal
Client SatisfactionMarval O’Farrell Mairal is best known for its transactional prowess in the mining sector and is a regular presence in the largest and most complex Argentina-related deals in the industry. The team is also recognised for the strength and depth of its regulatory work, where it assists clients with tax and provincial royalty scheme issues. Other active areas for the group include mining rights, project financing, environmental law, litigation and stakeholder management. The practice is led by the highly-rated Leonardo Rodríguez, who has dedicated his career to mining matters and amassed more than 20 years' direct industry experience. He is backed by a well-resourced cluster of associate talent, including Ignacio Alonso, a specialist in mining-related disputes; and the well-reviewed Agustina Dellacasa, who focuses on mining M&A and project development. The team saw the departure of Andrés Villarreal, a mining M&A lawyer, in April 2023, but can still call on the immense experience of mining stalwart Luis Lucero, a veteran practitioner who has retired from the partnership but continues to provide support in an of counsel role.
