On 5 August 2010, the San José Copper Mine collapsed, trapping 33 miners underground. The mine was about north of the city. The miners were deep and from the mine's entrance via spiraling underground ramps. Private, local, national and international resources cooperated in their rescue. The miners survived underground for 69 days until all were brought to the surface on 13 October 2010, a record period of time. This mine has been closed, but the industry of copper and gold mining is very important in the region.
