El Volcan is a small surface mine owned by ArcelorMittal located near the town of Rosario in Sonora state, Mexico. The mine is operated by contractors and supplies a concentrate product to ArcelorMittal's Lazaro Cardenas steel facility. El Volcan's ore is trucked roughly 120 kilometres from the mine site to its processing facilities, before being railed 130 kilometres to ArcelorMittal's port in Guaymas. This represents one of the longest raw haul distances within our dataset and makes costs at the operation much more sensitive to changes in diesel prices than would be typical of other operations in the area. El Volcan is set to permanently close in 2019 due to the depletion of its reserves.
