Humboldt County, NV Mining Claims & Land Ownership Map
Current BLM claim data, land ownership layers, and rockhounding-ready backcountry navigation for Humboldt County, NV — built for the field.
Humboldt County occupies Northwestern Nevada, stretching across open sagebrush basins, volcanic plateaus, and mineralized mountain ranges. Internationally celebrated for the world-famous black fire opals of Virgin Valley, major lithium deposits in the McDermitt Caldera, and historical gold strikes around Winnemucca, Paradise Valley, and Rebel Creek, the county draws lapidary artists, prospectors, and detectorists. Vast expanses of federal public domain land managed by the BLM Winnemucca District Office provide extensive space for small-scale placer prospecting and gemstone collecting.
Geologically, Humboldt County features a dynamic volcanic and structural environment shaped by Mid-Tertiary caldera eruptions, Basin and Range faulting, and Mesozoic intrusive rocks. Silica-saturated hydrothermal fluids and volcanic ash beds created the prized opalized wood and precious fire opals of Virgin Valley. Meanwhile, epithermal gold-silver quartz veins and lithium-bearing placer clays formed in surrounding volcanic basins, while weathering eroded hard-rock lodes into dry placer washes along the Santa Rosa and Osgood ranges.
Beyond fire opals and gold, rockhounds in Humboldt County discover opalite, jasper, petrified wood, chalcedony, and cinnabar across public domain terrain. Navigating mineral exploration in Humboldt County requires clear property boundary tracking. High-yield opal beds and gold districts contain dense clusters of active unpatented claims, interlocking with fee-dig properties and state land. Referencing an active Humboldt County mining claims map enables panners and crystal hunters to inspect current federal BLM records, verify open public domain ground, and explore 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 26,397 active and 118,666 historical mining claims in Humboldt County, NV, plus 1,147 Rockhound Hotspots — synced on a regular schedule directly from the BLM's own MLRS records.
