El Buitre

The concessions are located in the Sierra El Buitre, in the commune of Sierra Gorda, within a geologically significant sector of the Antofagasta Region. The area covers 1,390 hectares with verified mineralization, situated along the Sierra El Buitre fault, where vein-type mineralization predominates.

The immediate surroundings confirm the strategic nature of this portfolio, with proximity to large-scale projects: to the west, Lomas Bayas (Glencore); to the east, Centinela (Antofagasta Minerals); and within the broader area of influence, Mantos Blancos and Anglo American.

Currently, the following mining concessions in the Sierra El Buitre sector are active and fully compliant with patent payments:

• “Siembra 1/10”
