A district located in the environs of Alum Mountain and Gila Hot Springs.

The Alum Mountain mining district, also known as the Gila River, Alungen, and Copperas Creek districts, is located about 17 mi east-northeast of the Gila Fluorspar mining district. It was first discovered in 1892. In 1945, 3 short tons of ore were produced containing 1 oz/ton Au and 21 oz/ton Ag from volcanic epithermal vein deposits. Approximately 1,100 short tons of meerschaum have been produced from three shafts in the area in 1885. It is used in manufacturing articles such as cigar holders, pipes, and mouthpieces used by smokers. Some of the material was pressed into tobacco pipes and other
material was used as an absorbent for nitroglycerine. The best meerschaum is impurity free and forms in blocks from which pipes can be carved. These may be very ornate with clay, amber, wood, metals, and other materials added to heighten their commercial appeal. Lower-grade material is processed to free it of impurities and pressed or molded into shape.
