There is gold on the East side of Kirtland Air Force Base in Albuquerque, gold near Tierjas above Albuquerque, gold near the top of the Jemez, gold on the Ortiz mine grant between Golden and Cerrillos, gold on the Rio Grande below Santa Fe, gold on the Rio Grande above Santa Fe, Gold on the upper Pecos above Pecos, gold on lower Coyote creek near Mora, gold on Mt Baldy above the Cimmaron, gold in the Red River valley, gold in and east of Chama in the Brazos gorge and at 10,000 feet on Placitas creek, gold in the eastern Manzano mountains, gold in Ancho and White Oaks in the Jicarilla mountains, gold around and above Monticello, gold on and west of Caballo mountain, gold in the area around Hillsboro, gold at Pinos Altos, gold in the Burro mountains, gold at Gold Hill, gold on the little Blue river and gold in and around Mogollon.
Those are the places I personally know to have mineable gold in New Mexico. I know of others but I've promised not to share those other locations. Although several are associated with nearby volcanic activity none of them are on or in volcanoes.
The Ortiz mine grant west of Albuquerque is a very productive historical and current gold producer. That's where my group has mined for the last few years. That's where Edison built the world's largest drywasher plant and failed spectacularly. Edison believed that an electrostatic charge would increase the retention of gold and he gladly took other peoples money to prove it would work. It didn't and doesn't. The episode became known as
Edison's Folly. We've sampled some of Edison's tailings and found good gold values.
In New Mexico the
Rio Grande Rift is the dominant and controlling geological feature. To understand New Mexico geology you need to get an understanding of the Rift dynamics. Along and above the Rio Grande the
Santa Fe Group of deposits (PDF) fill the rift. These are mostly unconsolidated sand and stone debris and it's not uncommon to find small scattered gold in the Santa Fe Group.
For Rio Rancho itself you will be working in the Santa Fe group with some addition from the Jemez creek deposits. The Rio Puerco is 50 miles south of Albuquerque and has no association with the geology around Albuquerque and Rio Rancho.
