Rosedale Placer District — Socorro County

Gold Mining Site NM • Socorro County County
Description
NMBGMR mining district DIS225 (Rosedale) — documented placer gold in Socorro County, New Mexico. Discovery circa 1882; gold occurs in Tertiary–Holocene alluvial fans, terrace gravels, and stream deposits per NMBGMR.
Historical Notes
McLemore (1994) lists Rosedale among 36 New Mexico mining districts containing placer gold (NMBGMR Resource Map 24, district DIS225). Estimated placer production: trace to small-scale placer production (est. 15 oz) from 1828–1991 statewide context (662,000 oz total NM placer production). Production period: 1882-1981. District cumulative production (all commodities): $500,000. Deposit types: volcanic-epithermal vein, placer gold. Also known as: San Mateo Mountains. 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 (DIS225).
