Largest open pit copper mine in the world at Santa Rita, New Mexico. Copper was discovered here by an officer of the Spanish army in 1800 who sold the same to a wealthy Spanish merchant. Pure native copper was transported by pack mule to Mexico City to enter the royal mint for coinage. In 1900 a young mining engineer became interested in the development and was instrumental in the ultimate success of the Chino Copper Company. The ore is now shipped to Hurley, a short distance to the south, where it is put through a five million dollar smelter
