The abandoned mine of Achada do Gamo
An abandoned open pit mine
São Domingos, Portugal
Located in São Domingos (province of Alentejo) south of Lisbon, capital of Portugal, the mine of Achada do Gamo is an abandoned open pit mine. Located in the heart of the Iberian Pyrite Belt, which extends from southern Portugal to Spain, the region of the mine consists of the outcropping volcanic and sedimentary rocks that vary in age from 542 to 251 million years.
The history of mining in the area dates back over 4300 years when Phoenicians and Carthaginians already harvested copper during the Chalcolithic period (Copper Age).
It will nevertheless expect the ancient Romans who intensified the production of copper on a large scale. For nearly 400 years, they exploit a mine of copper and pyrite. At this time, the mines could reach a depth of over 40 meters.
The industrial revolution modernize extraction techniques and a British company called Barry Mason took control of the São Domingos mine. They create the Achada do Gamo mine around 1858 and it will continue its operation until 1966, when it closed due to ore depletion. With its intensive operations, and hundred years later at its closure, the open pit mine was a depth of 120 meters and a perimeter of approximately 2 km. It is calculated that all the periods of mining resulted in the production of 25 Mt, and mine waste material in the area is estimated at several hundred thousand tons. In this context, important environmental problems are associated, which are visible within an area around 50 km2.
