Its workings are reached by a long sloping roadway with many spiral turns (a diagram shows ten turns), not by a vertical mineshaft. The San José Mine is located 45 kilometers northwest of Copiapó. The mine began operations in 1889. In 1957, Jorge Kemeny Letay, a Hungarian immigrant founded the San Esteban Mining Company (). According to Terra, the mine's annual sales surpassed 20 million dollars.

On June 9, it was announced that 22 more miners, who had been waiting for 30 hours, were rescued by the crews, while 13 remained buried. On June 10, an official said that there was little chance that the 12 remaining miners were alive, as 9 of them were riding up an elevator when the blast happened, sending the cage down the shaft, and the other 3 were underground, where methane levels were dangerously high after the explosion. Officials were also concerned that the mine could flood.
