    The Tres Pacos mine is an abandoned mine located in the municipality of Cuevas de Almanzora. Iron minerals such as hematite were extracted from this mine.

    The mine began operating at the end of the 19th century and until 1935, when the activity was abandoned. The mineral was transported by an aerial cable to the Cala Picota pier, 13 kilometers away, completely crossing the Almagro mountain range. The mineral was first processed in the mine itself, using various furnaces fueled by charcoal.

      The mining industrial heritage of Cuevas del Almanzora has not yet been fully valued, as is the case of the Tres Pacos Mine. Iron minerals, specifically hematite, were extracted from its galleries. The extracted material was transported by an aerial cable of about 13.3 km in length to Cala Picotas.
      The feeding of the ovens was done through the upper part or mouths and the discharge through the lower openings. For loading, a layer of iron ore and a layer of charcoal were arranged alternately to activate combustion and produce carbon monoxide (CO gas) that acted to reduce the ore.
      The first works were carried out by open pit cutting, later moving on to interior work, for which four levels were opened at 25, 50, 75 and 100 m., linked together by transversals, counterholes and chimneys. The main extraction gallery consisted of an inclined plane into which the different levels ended. It also had a drainage gallery that, capturing water below level 100, led it to the Granadico ravine.

      The project for this aerial cable was presented in 1911, and its construction was authorized in July 1912. The system chosen was that of Adolf Bleichert, powered by electricity produced by a generator adapted to a steam engine, with a transport capacity 30 tons per hour. The cable originated in the mine facilities, located in the Sierra de Almagro, near Cuevas, and reached the coast, completely crossing Sierra Almagrera, as we have already mentioned, in Cala Picotas.
