Navajo Mine begins large-scale mining operations in 1963 by its original operator, Utah International in areas south of Fruitland, New Mexico on the Navajo Nation. Over the years, it has become one of the largest surface mining operations in the United States. The Navajo Mine is the sole supplier of coal to the adjacent Four Corners Power Plant (FCPP). The electricity generated from the Navajo Mine coal plays a significant role in meeting the energy needs of the rapidly growing Southwest.
