Grant County, NM Mining Claims & Land Ownership Map
Current BLM claim data, land ownership layers, and rockhounding-ready backcountry navigation for Grant County, NM — built for the field.
Grant County forms a premier mineral powerhouse in Southwestern New Mexico, anchored by the rugged Gila National Forest and historic mining districts around Silver City, Pinos Altos, and Santa Rita. Renowned for rich 19th-century placer gold strikes and massive copper-silver lode deposits, the county holds a heavy concentration of active unpatented mining claims. Modern prospectors, metal detectorists, and rockhounds explore vast public domain lands managed by the BLM Las Cruces District Office and the Gila National Forest.
Geologically, Grant County occupies a hyper-mineralized zone shaped by Laramide porphyry intrusions and complex faulting. Hydrothermal solutions injected rich gold-bearing quartz fissure veins, copper-zinc replacement orebodies, and turquoise veins into Precambrian granites and Paleozoic limestones. Millennia of fluvial erosion weathered hard-rock lodes, washing heavy placer gold into alluvial gravels along Pinos Altos Creek, Bear Creek, and the Gila River watershed. Beyond precious metals, public domain terrain yields world-class turquoise, banded agates, fire agates, and quartz crystals.
Navigating Grant County prospecting requires strict spatial boundary tracking. Active placer and lode claims line primary creek beds and mineralized mountain slopes, interlocking with private patented copper properties and protected wilderness boundaries. Utilizing an active Grant County mining claims map enables panners, dry-washers, and crystal collectors to cross-reference live federal MLRS records, confirm open public domain land, and navigate backcountry access routes legally and safely.

Staked Maps isn't crowd-sourced guesswork. Current and historical claim boundaries are parsed directly from the Bureau of Land Management's Mineral & Land Records System (MLRS), which replaced the legacy LR2000 mining claim system in 2021, and kept in sync with our database on a regular schedule. Rockhound Hotspots draw from the USGS Mineral Resources Data System (MRDS), cross-referenced by material so you can see exactly what's been found at a given site. For legal filings, always confirm current status directly with your BLM state office of record; Staked Maps is a research and navigation tool, not a substitute for the official record.
Directly from the Bureau of Land Management's official MLRS (Mineral & Land Records System) case-recordation records, synced into our database on a regular schedule — not scraped or crowd-sourced.
Staked Maps displays the status reported by BLM. Records with a case disposition of Active are labeled Active; historical records come from BLM's closed-claims dataset. These statuses are research information, not a Staked Maps legal determination of claim validity, discovery, ownership or compliance. Verify the current record through MLRS before acting on it.
Free users can search by county. Paid plans add search by claim serial number, plus each claim's full legal (aliquot) description and BLM records link.
Staked Maps currently tracks 4,491 current federal mining claim/site records and 21,530 historical claim records from BLM MLRS, plus 721 Grant County, NM mineral-occurrence records derived from USGS MRDS.
A premium map layer of documented mineral occurrences, prospects and mines sourced from USGS MRDS and labeled by material where available. These records are research leads, not a directory of verified public collecting sites.
