Gold Mining Site NM • Rio Arriba County County

NMBGMR mining district DIS149 (Chama Placers) — documented placer gold in Rio Arriba County, New Mexico. Discovery circa 1848; gold occurs in Tertiary–Holocene alluvial fans, terrace gravels, and stream deposits per NMBGMR.
Historical Notes
McLemore (1994) lists Chama Placers among 36 New Mexico mining districts containing placer gold (NMBGMR Resource Map 24, district DIS149). Estimated placer production: trace to small-scale placer production (est. 100 oz) from 1828–1991 statewide context (662,000 oz total NM placer production). Production period: 1848-1938?. District cumulative production (all commodities): <$35,000. Deposit types: placer gold. Also known as: Abiquiu, Abuiqui placers, Lumberton, Rio Chama Placers. Placer gold occurs as native gold and electrum in incised valleys and alluvial fans. Most economic placers were discovered by 1900; recreational panning may find fine colors — verify land status before prospecting. Coordinates approximate the district centroid from NMBGMR Resource Map 24 GIS (DIS149).
