Granite County, MT Mining Claims & Land Ownership Map
Current BLM claim data, land ownership layers, and rockhounding-ready backcountry navigation for Granite County, MT — built for the field.
Granite County occupies a world-famous mineral realm in West-Central Montana, framed by the Flint Creek Range, the Sapphire Mountains, and the Anaconda-Pintler Wilderness. Celebrated internationally for gem-grade Rock Creek sapphires and historical silver-gold bonanzas around Philipsburg, the county draws lapidary artists, gold panners, and metal detectorists. Public domain lands administered by the Beaverhead-Deerlodge National Forest and the BLM Butte Field Office provide vast mountain space for recreational prospecting and gemstone hunting.
Geologically, Granite County features complex thrust faulting, Paleozoic sedimentary formations, and Tertiary granitic stocks. Hydrothermal solutions injected rich silver-bearing manganese quartz veins and polymetallic lead-zinc-gold ores into limestone host rocks, creating famous lodes at the Granite Mountain and Bi-Metallic mines. Glacial action and stream erosion weathered surrounding volcanic rocks and pegmatites, concentrating rich alluvial sapphire deposits in the gravels of Rock Creek (Gem Mountain) and placer gold along Flint Creek, Henderson Creek, and Princeton Gulch.
Successful rockhounding and prospecting in Granite County demand clear property boundary tracking. High-yield sapphire gravels and historic gold districts contain dense concentrations of unpatented lode and placer claims, interlocking with private fee-dig mines and commercial holdings. Referencing an active Granite County mining claims map enables panners and crystal hunters to inspect current federal BLM records, verify open public domain land, and explore mountain drainages 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 1,564 active and 16,499 historical mining claims in Granite County, MT, plus 840 Rockhound Hotspots — synced on a regular schedule directly from the BLM's own MLRS records.
