In addition to assisting from a mining regulatory perspective, the seven-strong department at full-service law firm Claro & Cia. assists with mining sector-related financings, project development, M&A deals and litigation; it is also increasingly active in environmental cases further to the creation of the Environmental Courts and Environmental Superintendence. Leading the firm’s natural resources team, Nicolás Eyzaguirre‘s broad practice includes advising local and foreign companies on developing mining sector projects, as well as transactional and contentious matters; former senior associate Joaquín Rodríguez, who was raised to the partnership in January 2022, focuses on natural resources transactions.

The natural resources group is led by Nicolás Eyzaguirre, who ‘stands out for his knowledge‘; bolstering the team’s offering, former senior associate Joaquín Rodríguez -who has a transactions-driven profile- was made partner in January 2022, and former Superintendency of the Environment trial lawyer Tomás Darricades was rehired in July 2021 from Moreno Sáez & Avilés.
