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 in each of the last three years and 6 million pounds of molybdenum in 2020*. For more information about Freeport-McMoRan's Morenci Operations visit
