Freeport-McMoRan’s Morenci Operations started in 1872, when the first commercial mining operations were developed. The initial underground mining began in 1881 and the mine later transitioned to open-pit mining beginning in 1937. In 1987 Morenci commissioned its first solution extraction/electrowinning plant and continued as a pioneer for mining technology. Today Morenci is one of North America’s largest producers of copper and one of the largest open-pit mines in the world with great potential for growth and continued prosperity.

Morenci’s production, including our joint venture partner’s share, totaled 1.0 billion pounds of copper and 5 million pounds of molybdenum in 2019*. For more information about Freeport-McMoRan's Morenci Operations visit
