Geology and mineral resources of the Wild Horse Mesa area, Burro Mountains, Grant County, New Mexico
— Virginia T. McLemore

The alteration, vein textures, metal association, and proximity to the ring-fracture zone of the Schoolhouse Mountain caldera indicate that the mineral deposits at Wild Horse Mesa in the eastern Telegraph district of the northern Burro Mountains are volcanic-epithermal veins. in the Wild Horse Mesa area, there are four types of mineral deposits, including fluorite veins, uranium vein and minor stratabound deposits, base metal veins, and barite veins. Mineral distribution appears to be controlled by the Schoolhouse Mountain fault. Fluorite and uranium veins occur west of the fault, copper with gold and silver occur along the fault, and barite without significant metals occurs east of the fault. The alteration and form of the veins indicate that ascending fluids, not descending fluids, formed the vein deposits. The mineral resource potential for undiscovered volcanic-epithermal vein deposits in the Wild Horse Mesa area is good. The presence of gold concentrations in surface samples and the interpretation of the deposits being at the top of a volcanic-epithermal system suggest that additional deposits are most likely to be deep. The best potential is associated with faults west of, and including, the Schoolhouse Mountain fault.
