The state’s roughly 240 “active registered” mines, 83 percent of them producing aggregate and stone, employed 5,156 people in 2009, paid them $287 million, and produced minerals worth about $1.8 billion – good for a ranking of 20th nationally without counting oil and gas.
The big value numbers come from coal ($736 million in 2009), potash ($491 million), and copper ($290 million and hiring again).
Except for potash and salt mines around Carlsbad, the mines are located in the southwest quadrant and in a broad and mostly rural northern arc that starts at Raton, swings south to include Belen and Albuquerque, edges north and west to Grants and then goes to the Arizona.
