History

Ajo is the Spanish word for garlic (Spanish pronunciation: [ˈaxo]). The Spanish may have named the place using the familiar word in place of the similar-sounding Oʼodham word for paint (oʼoho). The Tohono Oʼodham people obtained red paint pigments from the area.

Native Americans, Spaniards, and Americans have all extracted mineral wealth from Ajo's abundant ore deposits. In the early nineteenth century, there was a Spanish mine nicknamed "Old Bat Hole" that was abandoned due to Indian raids. Tom Childs Sr., found the deserted mine complete with a 60-foot (18 m) shaft, mesquite ladders, and rawhide buckets in 1847. He did not stay long at that time because he was on his way to the silver mines near Magdalena de Kino.

Thirty-five years later, Childs and his son returned with a friend and started developing the abandoned mine.

In the year 1884, the camp at Ajo was practically abandoned. Not a soul was in camp when Tom Childs Sr., and his son arrived. With them was Washington Michael Jacobs of Tucson, Arizona ... Childs and Jacobs located the mining claim which constituted most of the old Ajo group of mines. They made a permanent camp and worked the mines.
