Owyhee County, ID Mining Claims & Land Ownership Map
Current BLM claim data, land ownership layers, and rockhounding-ready backcountry navigation for Owyhee County, ID — built for the field.
Owyhee County forms a vast, high-desert mineral haven in southwestern Idaho, bounded by the rugged Owyhee Mountains and the deep canyons of the Owyhee River. Famous for the historic hard-rock silver and gold bonanzas of Silver City, De Lamar, and Ruby City, the region holds a dense concentration of active unpatented mining claims. Modern prospectors, metal detectorists, and lapidary collectors explore open desert washes, mountain gulches, and volcanic plateaus managed primarily by the BLM Owyhee Field Office.
Geologically, Owyhee County sits within a dynamic volcanic and tectonic realm. Mid-Tertiary rhyolitic and basaltic volcanic flows erupted over older granitic basement rocks, hydrothermally depositing high-grade epithermal silver and gold quartz veins. Weathering and seasonal desert erosion scattered heavy placer gold into gulches surrounding War Eagle Mountain, while volcanic activity and silica-rich hydrothermal solutions created world-famous rockhounding deposits. Lapidary enthusiasts flock to public domain lands for renowned Owyhee picture jasper, porcelain jasper, thundereggs, agates, and petrified wood.
Navigating Owyhee County requires strict spatial boundary tracking. Active lode claims cover historic high-grade vein structures, while placer claims line alluvial washes, closely interlocking with private ranch lands, state endowment parcels, and wilderness study areas. Referencing an active Owyhee County mining claims map allows prospectors and rockhounds to trace live federal MLRS records, differentiate placer and lode boundaries, and identify open public domain ground before heading into the backcountry.

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 2,457 current federal mining claim/site records and 13,661 historical claim records from BLM MLRS, plus 296 Owyhee County, ID 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.
