The Huércal-Overa Investigation permit is located inthe north of the Andalusian province of Almería (south-east of Spain), in the municipality of the same name. The distance to Cartagena, one of the largest ports in Spain, is approximately of 100 km, the same distance as to the capital of the province, Almeria.
During the 19th and 20th centuries, under English Regency, the Cuesta Alta Mine was exploited in that area, with high grades on secondary Cobalt mineralization. The main mineral occurrence relates to the former Cerro Minado area, where Cobalt, Copper and Nickel were benefited.
The mineralization is concentrated in the vicinity of the thrust faults between carbonate formations and the mylonites of the basal thrust faults.
The dolomitic formations are intensely fractured, developing a sort of dense “stockwork” of millimeter-wide veins, where the Co-Cu-Ni mineralization is hosted.
