The Workman Creek Uranium Mines Site (the Site) is in the Workman Creek watershed in Gila County, between Young and Globe, Arizona. Access to the Site is from SR 288 between mileposts 284 and 285 on Forest Road (FR) 487.

Uranium was discovered in the area as early as 1950 when above normal radioactivity was detected. Development was slow due to the spotty nature of the deposits and the inaccessibility of the area. Active mining did not occur until 1954 and in 1955 a uranium orebuying station was built in Globe, which received ore shipments from the Workman Site mines. In general, most of the uranium produced from the area was of lowgrade and was uneconomical to mine. By 1957, ore production from the area mines stopped and the orebuying station was closed.

Exploratory work occurred off and on through the 1980’s and included mining, drilling, and sampling to evaluate the remaining uranium reserves. Several mine access roads were built throughout the area. Available information indicates that the Creekside and Cascade Campgrounds may have been used as ore staging areas during active mining.
