Historical Notes
McLemore (1994) lists Las Vegas among 36 New Mexico mining districts containing placer gold (NMBGMR Resource Map 24, district DIS163). Estimated placer production: minor or unrecorded placer production from 1828–1991 statewide context (662,000 oz total NM placer production). Production period: 1907. District cumulative production (all commodities): $100,000. Deposit types: placer gold, sedimentary, sandstone uranium. 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 (DIS163).
