Studio

With an origin anchored in Antofagasta and consolidated in Santiago, Claussen & Velasco is a studio with a DNA deeply linked to natural resources. We combine a proven track record in highly complex litigation with the comprehensive strategic advice required by large mining projects in the country, understanding reality from the ground up.

We have redefined legal advice for large mining, combining technical rigor and strategic vision in the face of the most complex regulatory challenges.

We don't just respond to legal problems; we understand the operational reality of the mining sector. Based on professional excellence and an absolute technical mastery of natural resources, we transform the traditional role of the lawyer. We are not passive outsiders, but true strategic allies who are thoroughly involved in the field to understand the business behind the file

In the dynamic environment of mining and the environment, reacting is not enough. We focus on proactive anticipation of regulatory risks, integrating business vision and technology to deliver tangible results. We lead in complex litigation and specialized advice on investment projects because we design precise strategies that allow us to always be one step ahead.
