This 20 stamp ore crusher, was donated in 1989 by Mr. and Mrs. Joseph Jones of Albuquerque, New Mexico. Twenty eight days were required for five men, all volunteers to disassemble and move the mill to Apache Junction, Arizona. This mill was state of the art technology for recovering gold in the 1800s. Rare, historical, surviving equipment of this nature today can be counted on one hand, let alone in such great condition.
A stamp mill (or stamp battery or stamping mill) is a type of mill machine that crushes material by pounding rather than grinding, either for further processing or for extraction of metallic ores. Breaking material down is a type of unit operation.
A group of hard working men spent over thirty days in Bland, New Mexico, salvaging the old twenty-stamp mill and building. It was five stories terraced on the side of the canyon wall. Each day the men worked 10 to 12 hours and took only two days off during the entire project according to Mayor Bob Schoose, author of Goldfield Boom to Bust.
The twenty-stamp mill was originally located on the grounds of the Goldfield Ghost Town in Apache Junction, Arizona.
Today the Superstition Mountain Museum is home to the twenty-stamp mill. A group of dedicated men interested in preserving the history of mining have donated endless hours and days to restore our mill in addition to two other mills, one in Cave Creek Arizona, and the other in Goff, California.
