Mineral resources of the southern Sangre de Cristo Mountains, Santa Fe and San Miguel Counties, New Mexico
— Virginia T. McLemore
Precambrian massive-sulfide, Precambrian vein and replacement, pegmatites, sedimentary copper, sedimentary iron, coal and placer gold deposits are found in nine mining districts in the southern Sangre de Cristo Mountains. The largest of these deposits is the Pecos mine in the Willow Creek district, where 2.3 million tons of ore containing Pb, Zn, Cu, Ag and Au worth over $40 million were produced. The Pecos mine is a Precambrian volcanic-hosted massive-sulfide deposit. Production from other types of deposits in the southern Sangre de Cristo Mountains is insignificant. Exploration is currently underway at a massive-sulfide deposit at Jones Hill in the Santa Fe district. Reclamation is proceeding at the Pecos mine and Alamitos Canyon mill.
