In 1883, Frank Schultz located the first mine in the area. The name Mammoth was given to the mine because it was believed that the gold ore deposits were of mammoth proportions.
The mines soon realized that is was impossible to work the ore at the mine site. A stamp mill had to be built to solve the problem and the best place for the mill was along the San Pedro River. The location of the stamp mill became known as Mammoth, named after the mine. In the beginning, the ore was hauled down to the mill by mule teams and wagons. Then in 1903, aerial trams were constructed. Bucket loads of ore were sent down from the mine to the mill.
Throughout the 1880’s, the town was one of the busiest mining camps in the country. The Mammoth post office was established in 1887.
The Mammoth Mine changed owners and work were shut down in 1895. During this time, the mine developed a new system of milling.
When molybdenum was found in the tailings during 1936, the mine had a short-lived resurgence. The town was incorporated in 1958.
The discovery of the nearby San Manuel Mine brought Mammoth alive again. The San Manuel Mine opened in the 1950’s, bringing more jobs to the surrounding mining towns. Today, production of metal continues to play a large role in the town’s economy, along with ranching.
