Sierra County, NM Mining Claims & Land Ownership Map
Current BLM claim data, land ownership layers, and rockhounding-ready backcountry navigation for Sierra County, NM — built for the field.
Sierra County encompasses a hyper-mineralized region in South-Central New Mexico, stretching from the shores of Elephant Butte Reservoir across the Black Range and Caballo Mountains. Famed for the ultra-rich placer gold strikes of Hillsboro and the historic silver bonanzas of Lake Valley, the county draws modern prospectors, detectorists, and rockhounds. Expansive public domain lands managed by the BLM Las Cruces District Office and the Gila National Forest offer abundant space for field exploration.
Geologically, Sierra County features complex faulting along the Rio Grande Rift, Laramide igneous intrusions, and Tertiary volcanic structures. Hydrothermal fluids injected high-grade gold quartz veins, silver-lead replacement deposits, and copper lodes into faulted Paleozoic limestones and volcanic host rocks. Arid erosion weathered hard-rock veins, distributing coarse placer gold and heavy nuggets across dry washes in the Hillsboro, Animas Creek, and Apache mining districts. For rockhounds, public terrain yields fire agate, fluorite, vanadinite, and jasper.
Prospecting in Sierra County requires strict spatial boundary tracking. Gold-bearing washes and historic silver lodes host dense clusters of unpatented placer and lode claims, interlocking with private ranches and state trust land. Utilizing an active Sierra County mining claims map allows dry-washers, detectorists, and rockhounds to check live federal records, confirm unclaimed public domain ground, and navigate backcountry access routes legally and safely.

Staked Maps isn't crowd-sourced guesswork. Active and historical claim boundaries are parsed directly from the Bureau of Land Management's own MLRS/LR2000 case-recordation system — the same records BLM state offices use internally — 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/LR2000 case-recordation records, synced into our database on a regular schedule — not scraped or crowd-sourced.
Yes. The free tier gives you the interactive claims map, land ownership overlays, and basemap layers for your current state, auto-detected via GPS — no subscription required. Paid plans add more states plus premium data like full legal descriptions, historical claims, offline downloads, and Rockhound Hotspots.
Active claims currently have valid, in-good-standing filings with the BLM. Historical claims are expired or closed filings — still useful for understanding an area's mining history and past activity.
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.
A premium map layer of known mineral and gem collecting sites — sourced from USGS records and labeled by material where available (e.g. turquoise, opal, jasper) — for rockhounds looking for their next find.
Staked Maps currently tracks 939 active and 19,772 historical mining claims in Sierra County, NM, plus 611 Rockhound Hotspots — synced on a regular schedule directly from the BLM's own MLRS records.
Yes — the live map covers all of New Mexico, not just Sierra County. Other New Mexico counties with a dedicated page: Grant County, Luna County, Taos County and Socorro County.
