Open Pit Mining
Santa Rita Copper Mine
It was here at the Santa Rita Mine that they introduced new mining technology and techniques including the new concept of "open-pit" mining.
It took steam, coal, and iron to bring success to Santa Rita. When the railroad arrived in 1898, it opened a new era for mining. A successful copper mine needed to move tonnage — lots of tonnage. With the railroad in place, Santa Rita was waiting to be discovered.
In 1905, a young M.I.T. graduate named John M. Sully, determined that many small underground mines here were sitting atop an enormous copper ore body of great potential. His systematic and skillful examination of the ore body was followed by his commitment to find funding to develop this great mine. Sully’s success earned him recognition as one of the great engineers of the period.
Another contributor to the success of this mine was a young engineer named Daniel C. Jackling. His new method of open-pit mining of large, low-grade copper ore, earned him recognition across the globe.
With funding in place and engineering
Erected by Freeport-McMoRan Copper & Gold.

1. Open Pit Mining: A Breakthrough In Mineral Extraction. In 1909, the Chino Mine becomes the the first site for “open-pit” mining under the Chino Copper Company. The railroad arrives in Santa Rita* in 1898, allowing for massive amounts of copper to be transported. In 1905, John M. Sully determines that the many tunnel mines riddling the region are all accessing a single, massive copper body. (Submitted on October 16, 2020, by Cosmos Mariner of Cape Canaveral, Florida.)

Jackling was a mining and metallurgical engineer who revolutionized the copper mining industry early in the 20th century by pioneering and developing the processing of low-grade porphyry copper ores.
