The Kelly was the last mine to be developed in Butte. It was built in 1949 and closed in 1980.
Cornelius Francis Kelley came to Butte, MT from Mineral Hill, NV in 1883 at the age of eight. He worked as a water boy on the Butte Hill and part time as a nipper–essentially, a delivery boy of machinery to the miners–underground at the Anaconda Mine.
It wasn’t long before he worked in the engineering department and worked his way up the corporate ladder. In 1918, Kelley got the name from the President for the Anaconda Copper Mining Company.
By 1949, Cornelius opened the Kelley mine when the demand for copper increased after World War II. He saw this as the adaptive solution to the economic conditions at the time. Towards the end of its life, it was the last underground mine still in operation before closing its shafts in 1974.
The mines main production was Lead, Copper, Silver, and Zinc, but does not disclude the countless other mineral mixtures that can also be found. It is also famous for the rare variety of blue smithsonite that can only be found here in Kelly. The history is as rich as the variety of material discoverable here.
The Kelley has three shafts and two headframes, the larger the tallest on the hill. Even the mining process itself took on new proportions with block-caving mining techniques, which increased production to over 15,000 tons a day.
The first Kelly head frame is still on site. It is quite small and was erected in 1906.
