Historic and active gold-bearing mining districts across New Mexico, mapped with deposit geology, production history, land ownership, and current claim/operator status compiled from USGS, NMBGMR, EMNRD, and BLM records.

Read before use:this tool synthesizes public USGS, NM Bureau of Geology & Mineral Resources, EMNRD, and BLM records assembled by an AI research process in July 2026 — it is a research starting point, not a survey, title report, or investment/legal advice. Historic production figures frequently conflict between sources and are reported as found, not reconciled. No live claim data is embedded here — before staking, drilling, or transacting, verify current claim status at reports.blm.gov/reports/MLRS, permit status with NM EMNRD Mining & Minerals Division, and water rights with the NM Office of the State Engineer.
Every USGS MRDS site with gold among its recorded commodities — larger dot = currently producing, smaller = past producer/prospect/occurrence. Color is a screening heuristic, not a legal determination: green = BLM land, open to mineral entry, no claim overlap found; orange = ambiguous (Forest Service/other/unknown ownership, a Wilderness Study Area, or a closed/expired prior claim); red = private land, an active claim already here, or legally closed. Always verify at reports.blm.gov/reports/MLRS before acting — click a point for the reasoning behind its color and a link to the source MRDS record.
Every USGS GNIS “Populated Place” in New Mexico — GNIS doesn’t have a separate “ghost town” category, so this one dataset covers both historic mining camps/ghost towns and small currently-inhabited towns together, with no way to tell from the data alone which is which.
BLM MLRS claim boundaries, synced weekly — informational and best-effort, not a substitute for a title or professional claims search. Confirm current status at reports.blm.gov/reports/MLRS before acting. Orange = active, gray = closed.
NM Office of the State Engineer’s county-assessor parcel service — public tax record (owner name, mailing address, legal description), covering the 16 counties with a gold district. Fetched live for whatever’s in view, not synced or stored — zoom in to load (statewide detail would be hundreds of thousands of parcels). Owner-name labels appear once you’re zoomed in close enough to read them; click or hover any parcel for the full record. Always verify at the county assessor before acting; ownership/mailing data can lag behind recent sales.
Real roads from USFS’s Motor Vehicle Use Map + BLM’s national road inventory — the same sources “Check this spot” already checks, now drawn as actual lines you can follow. Solid green = passenger vehicle OK; dashed amber = high-clearance/4WD only; dotted gray = motorized-legal but vehicle class not specified in the source. Fetched live for whatever’s in view, not synced or stored. BLM’s own road inventory is genuinely sparse outside National Forest land — a gap here doesn’t mean no road exists. Always verify current status (seasonal closures, washouts, gates) before driving out.

~7 mi grid cells inside NM’s real gold-bearing belts, EXCLUDING anywhere within ~0.28 mi (1,500 ft — the legal maximum length of one lode mining claim, 30 U.S.C. § 23) of an already-known mine — this asks “where might undiscovered gold be,” not a ranking of already-productive ground. Pale gold → rust = low → high score, from bedrock lithology + rock-contact proximity + copper/lead/zinc/barium/cobalt geochem anomaly. An experimental screening heuristic, not a resource estimate — click a point for the full reasoning and its (separately scored) land accessibility.
NMBGMR’s own real mapped fault traces — not this site’s own hand-curated “vein/fault trend hint” lines above, a different, short-extension dataset. As of this build, the live source service returns zero usable geometry for this specific layer (a confirmed gap on NMBGMR’s end, not this app’s) — the toggle and pipeline are live and ready, expect this to populate automatically once the source is restored.
Terrain
Tip: hover anywhere on the map and pause for a second or two to see everything we have on that point, no click needed.
Real USGS imagery+topo basemap and real county-assessor parcel boundaries/owner names — public tax record, not a survey-grade or title-grade parcel map. Belt overlays are generalized deposit-category regions from NMBGMR descriptions, not mapped contacts — click a shaded belt to isolate its districts. For actual mapped bedrock geology, see the “Bedrock geology (NMBGMR)” layer toggle below the map. Scroll/drag or arrow keys to pan; the map itself is not the accessible selection surface — use the list or table below for full keyboard/screen reader access.
