About us

Geometallurgica Consultores is a Chilean firm specializing in technical and strategic consulting in geometallurgy. We support teams in developing competencies, analyzing geological and metallurgical data, and implementing predictive models to optimize ore processing across small, medium, and large-scale mining operations.

With over 30 years of experience in mining geology and geometallurgy, our work is led by Sergio Spichiger, a geologist with strong technical background and an extensive career in the mining industry across Latin America and Africa. We have contributed to the development and implementation of geometallurgical models for copper, iron, platinum, diamonds, coal, and other mining operations, collaborating with multidisciplinary teams and promoting high standards of excellence throughout every stage of the process.

We believe that geometallurgical knowledge is a fundamental tool for informed decision-making processes and the design of long-term strategies. That’s why our work is focused on creating value through the integration of geological and metallurgical knowledge applied to mining operations.


Guided by the Geometallurgical Model Cycle approach, we offer a range of services from technical mentoring to auditing existing models, always adapting to the specific needs of each client.
