District lies on the southern end of the Schoolhouse Mountain caldera. A number of epithermal ore deposits have been formed by the volcanic activity.

The Telegraph mining district is located in the northern Big Burro Mountains and contains diverse range of mineral deposits. Small Laramide vein and volcanic epithermal deposits of precious- and base-metals, fluorite, manganese, uranium, and other commodities have been discovered and mined in the district. Total known production amounts to 1,700 lbs Cu, 1 oz Au, 1,350 oz Ag, 37,800 lbs Pb, minor Zn, 220 long tons of manganese ore, and 16,603 short tons of fluorite. In addition, stratabound uranium deposits occur in the Wild Horse Mesa area.
