Dentons fields ‘highly specialised professionals with extensive knowledge of the mining business’. In addition to its environmental, water and energy law credentials, the Santiago office is home to mining law experts who routinely assist both domestic and international clients on regulatory compliance, transactions, and high-stakes litigation and arbitration. Heading up the mining department, Gonzalo Nieto is a mining law and litigation expert, who assists at every stage of project development. Nieto’s experience ranges from the acquisition of mining concessions and obtaining permits and authorisations, to operational and closure stages; while José Ignacio Morán, advises mining companies on project-related regulatory, environmental and water law matters. The practice further includes Pauline Chiffelle, who focuses on defence-side mining disputes and regulatory proceedings. At associate level, senior Jaime Cruzat advises on royalty agreements, mining options, easements, mineral property planning and permitting; and Cristián Vial advises mining, energy and industrial companies on compliance and sustainability strategies that incorporate environmental, social and governance principles.
