Summary:

The Las Encinas operates the Aquila and Palomas open pit mines.

Aquila is a mine composed predominantly of magnetite with a hematite roof and sulphides and silicates gangue. The form of mineralization is massive and disseminated (mineralized hornfels, endoeskarn), with mineralized gaps. The mine site is hosted along a large failure line and between the contact of an intrusive diorite and limestone, and the shape of the deposit is slightly amorphous, crossed by a countless number of dams and mainly controlled by geological structures.

Palomas is a skarn mine with calcareous-pelitic ferrous type. It is formed by massive, and bordered by disseminated mineral. The bodies are disposed in concordant tabular horizons with a northwest and southeast-oriented pseudo stratification and northeast-oriented dip. The mineralization is predominantly magnetite and the gangue mineral is composed of garnet, pyrite and calcite. The surrounding rocks are skarn (calcareous protolyte, clayey calcareous and Cretaceous sandy) or hornfels (clayey protolyte). The stratigraphic sequence is affected by dyke intrusions of monzonitic and granite composition.
