A stock certificate belonging to the Big Ledge Copper Company.

This company was involved in the smelter plant expansion and mining operations in Mayer, Arizona. In August 1916 the company purchased additional mining claims and the old Treadwell smelter in Mayer. Capital was raised through the issuance of stock in the Big Ledge Copper Company, the operational entity of the Big Ledge Development Company. In 1917 the Big Ledge Copper Company acquired the Great Western Smelters Corporation and then contracted with Weber Chimney Company to build a 129-foot reinforced concrete chimney stack to increase the Mayer smelter's capacity to process ore.

However, due to a continuing lack of ore supply, the Mayer smelter, which had closed for 8 months from mid-1917 to early 1918, never reopened. By 1922, except for the stack, all remnants of the smelter were demolished. Today (2021) the Mayer smelter remains a symbol of a bygone era.
