Located in the state of Sonora; it is an open pit mine with a nominal crushing capacity of 27,000 tons per day. The crushed mineral is deposited in beds that carry out a process of heap leaching. It benefits from a ESDE plant facility for the final production of copper cathodes. The last deposit of mineral in bed was made in the third quarter of 2014, so production has been gradually decreasing since the fourth quarter in accordance to its recovery kinetics, expecting to conclude in the first semester of 2016.​
