COMMONWEALTH MINE Gold discovered here by cattleman Johnny Pearce in 1894. Mine yielded $30 million in ore before flooding ended profitable mining in 1904. Fuel oil for the mill was hauled from the railroad 16 miles away by 24 mule teams.

Proposed in this 1958 book. We have not found independent confirmation that this one was cast. That 1997 list covers only state highway right of way, so it does not reach markers on city streets, on tribal land, or in state and national parks.

1958 text, presented as a historical document. It uses the period's terms for Native people. The book proposed 100 markers for Arizona's highways and records 14 as cast when it went to press.

Arizona still marks its history under the same law: the State Historical Advisory Commission approves a marker, the Arizona State Library, Archives and Public Records certifies that its text is authentic and historically correct, and the Arizona Department of Transportation erects and maintains the markers on state highway right-of-way.
