Mining claims were first staked here in 1872 and during the early 1940s the Ajo mine was operating at its peak. The mine closed in 1984 after decades of copper production and growth of the community.

More recently, Freeport-McMoRan facilitated the construction of a 5—megawatt solar facility which began generating electricity in September 2011 and is intended to operate for 35 years. This project helps reduce our carbon footprint while also making use of otherwise inactive land.
