The golden hammers of La Herradura

The open pit gold mine of La Herradura Penmont in the northern state of Sonora, not far from the U.S. border, is improving its productivity through a combination of upgraded drill rigs and new rock drilling tools.
The La Herradura Penmont Mine, which is jointly owned by Fresnillo plc and Newmont USA, has been successfully mining its gold since it opened in 1996. Current production is around 190 million tonnes a year, largely due to the productivity of its DM 45 HP (high pressure) drill rigs from Atlas Copco, and more recently, a transition to the larger DML HP. Now the mine is making further improvements by introducing new rock drilling tools.
