The Aguablanca Nickel and Copper mine includes an open pit and underground mining developed from the bottom of the open pit. The mine is situated in Extremadura, south-west of Spain, approximately 100 km north of Sevilla and 30 km south of the town of Monesterio.
Aguablanca is located at the southern end of the Ossa-Morena Zone, and more specifically, of the Olivenza-Monesterio Antiform, a new copper belt in the south-west of Spain. The deposit consists of a mineralization of magmatic sulphides hosted by gabbros and gabronorites units.
The deposit is predominantly formed by pyrrothite, pentlandite, chalcopyrite and pyrite with some marcasite and covellite. Magnetite is usually present, as well as small amounts of the platinoid group minerals and gold, associated with sulphide minerals.
