Depressed copper prices in the 1920s and ’30s saw the eventual closure of mining operations in the Silver Bell district. The nearby Sasco smelter had shut down by 1921 and the Sasco townsite was abandoned.
The Sasco smelter, as seen in 1910, processed copper ore from the Silverbell Mountains.
Remnants of the ore-processing site are still visible today, including the concrete foundation of the furnace complex.
One renowned but short-lived smelter town in Arizona was Sasco, an acronym for the Southern Arizona Smelting Co. that operated the nearby smelter in 1908.
