Idaho Mining Claims Map: Current Claims, Land Status & Prospecting Rules

What Idaho's Current Mining Claim Data Shows

Staked Maps currently tracks 41,306 current/not-closed federal mining claim and site records in Idaho. "Current" means the BLM case disposition is not Closed as of the latest synchronization; "historical" refers to BLM's separate closed-claims dataset, discussed later on this page.

Idaho's current records are not spread evenly across the state, but which counties lead depends on how you count. BLM's own status field distinguishes an Active claim from one that is only Filed or otherwise pending, and current/not-closed and Active-specific rankings can put a different county in second place. The next section ranks Idaho's counties by BLM-status Active records specifically; the fuller current/not-closed county breakdown, including the same counties' Filed and Under Review shares, follows further down this page.

By claim/site type, lode records dominate: 37,780 records, or approximately 91.5% of Idaho's current total. Placer claims account for 2,822 (6.8%), mill site claims for 700 (1.7%) and tunnel site claims for 4 (<0.1%). Those four categories reconcile to the statewide total of 41,306.

One pattern is worth calling out directly: Washington County's current records are almost entirely lode claims (6,152 of 6,154), a very different composition from Lemhi County's mix (96.0% lode, with meaningful placer and mill site records alongside it).

Claim concentration is not a measure of mineral richness. A dense cluster of current federal records shows where claims and sites are concentrated in the BLM dataset. It does not prove production, mineral value, legal access, or that nearby unclaimed-looking land is open to mineral entry.

How Many Idaho Mining Claims Are Actually Active?

The word active needs to be used carefully with federal mining records. Staked Maps' current/not-closed dataset can include several BLM status values, and not every record in that group is necessarily labeled Active by BLM.

"Current / not-closed" is a Staked Maps grouping for records that are not part of the closed/historical dataset. It is not itself a BLM status label. "Active" is one specific status recorded by BLM, so the number of records labeled Active is smaller than the complete current/not-closed total.

Why this matters: at the latest Idaho data synchronization, 21,687 records carry the BLM status Active, approximately 52.5% of Idaho's current/not-closed dataset. Another 19,396 records (47.0%) are Filed, 220 (0.5%) are Under Review, 2 are under appeal with a stay granted, and 1 are Submitted. Filed and Under Review records have a pending BLM case action and should not be treated as identical to a fully Active claim. Verify a specific claim's exact status through BLM MLRS before relying on it.

Idaho's Top Counties by BLM Active Mining Claims

Ranked by BLM-status Active records specifically — the narrowest, most literal reading of "active mining claims" — Idaho's leading counties are:

Active-record counts and shares are computed directly from the Staked Maps database, using BLM's own case-disposition (status) field.

Where Are Idaho's Mining Claims Concentrated?

The table shows Idaho's 10 counties with the most current records. Separately, 115 records in the statewide total cannot currently be assigned to a specific county because their BLM source geometry is incomplete or unresolved.

The table above ranks counties by the broader current/not-closed total — Active, Filed, Under Review and other non-closed BLM statuses combined — rather than BLM-status Active alone. For the Active-only ranking, see the table earlier on this page.

Lemhi County

Lemhi County ranks first by current/not-closed records (8,125, 19.7% of the statewide total) and first by BLM-status Active records (4,724, 21.8% of the statewide Active total). Its composition is mixed rather than dominated by one claim type: 96.0% lode, 1.9% placer and 2.1% mill site. Lemhi County sits within east-central Idaho, home to the Idaho Cobalt Belt discussed in the regions section below.

Washington County

Washington County ranks second statewide by current/not-closed records with 6,154 (14.9%), a figure that does not appear in some older summaries of Idaho's leading counties. Its composition is almost entirely lode claims (6,152 of 6,154). By BLM-status Active records specifically, Washington ranks seventh (1,282, 5.9%); see the Active-records table above for why.

Shoshone County

Shoshone County ranks third by current/not-closed records (4,488, 10.9%) and second by BLM-status Active records (2,949, 13.6%). It lies within Idaho's Silver Valley, discussed in the regions section below, and its long association with silver, lead and zinc mining is reflected in its current claim composition (95.7% lode).

Valley County & Idaho County

By current/not-closed records, Idaho County ranks fourth (3,706, 9.0%) and Valley County ranks fifth (3,567, 8.6%). By BLM-status Active records, Valley County ranks third (2,623, 12.1%) and Idaho County fourth (1,909, 8.8%). Both counties have their own mining history, and their current claim mix — more placer-claim share than Washington or Shoshone counties — is not attributable to any single mineral or district.

Why Do Idaho Mining Claim Counts Differ Between Websites?

Different sites can report different Idaho mining-claim totals without either one being wrong. Common reasons include: counting only records BLM labels Active, versus including Filed, Under Review and other pending statuses too; including or excluding mill site and tunnel site records alongside lode and placer claims; using a different data-synchronization date than another source's last update; counting only records that were successfully mapped to a location, rather than every record in BLM's underlying system; or relying on an older data snapshot. BLM's own GIS metadata for this dataset notes that geospatial representations can be missing for cases that can't be geocoded from the legal land description recorded in MLRS. Staked Maps' own Idaho dataset currently has 115 current records that can't be assigned to a specific county for exactly this reason — their source geometry is incomplete or unresolved. A different total on another site is not, by itself, evidence that either dataset is wrong.

Current vs. Historical Mining Claims in Idaho

Idaho's mining history begins in 1860, when Elias Davidson Pierce discovered placer gold along Orofino Creek. The rush that followed established mining camps and boomtowns across the Clearwater, Boise Basin and Salmon River country, and later development of the Idaho Batholith's gold-bearing quartz veins and the Coeur d'Alene silver-lead-zinc district built on that early activity for more than a century.

Repeated historical claim activity in a district — a drainage or mountain range claimed and reclaimed across decades — can help researchers identify old mining corridors and areas with a long history of exploration. It does not establish current access, current mineral ownership, mineral potential, or availability for a new claim. That distinction matters most in a state like Idaho, where century-old districts sit alongside modern federal, state and private land designations.

Idaho Mining Regions Worth Understanding

Central Idaho Gold Country

Gold prospecting in Idaho traces back to 1860, when Elias Davidson Pierce found placer gold along Orofino Creek, triggering a rush that established mining camps across the Clearwater, Boise Basin and Salmon River country. Cretaceous granitic intrusion of the Idaho Batholith fractured older metasedimentary and volcanic rock, forming gold-bearing quartz veins that fed placer gravels downstream in the Salmon, Boise and Payette river systems as those veins eroded. Historic placer and lode development across this region underlies much of central Idaho's current claim activity, including Boise, Custer, Valley and Idaho counties.

Silver Valley

Shoshone County's Coeur d'Alene Mining District — commonly known as the Silver Valley — is one of the most significant silver, lead and zinc districts in U.S. mining history. Its long production history is reflected in Shoshone County's current claim data, which remains dominated by lode claims (95.7%).

Lemhi County and the Idaho Cobalt Belt

USGS describes the Idaho Cobalt Belt as a roughly 55-kilometer-long, northwest-trending belt of cobalt (with associated copper) deposits and prospects in the Salmon River Mountains of east-central Idaho, about 10 kilometers wide at its central part. The belt is centered on the Blackbird district in Lemhi County, historically North America's most significant primary cobalt resource. The Idaho Geological Survey's Staff Report T-26-01, a 2026 review of geoscientific studies of the Blackbird district and Idaho Cobalt Belt spanning 1902 to 2024, is the most current published research on the district — see the Idaho Geological Survey link in the official-sources section below rather than relying on older, generic geology summaries.

Southeastern Idaho Phosphate

Southeastern Idaho's open-pit phosphate mines supply approximately 22 to 25 percent of the nation's phosphate, according to BLM. BLM Idaho currently oversees 86 active phosphate leases in eastern Idaho covering a total of roughly 44,000 acres.

Not Everything Mined in Idaho Appears as a Mining Claim

Phosphate is not locatable under the 1872 Mining Law the way lode and placer claims are. It is a leasable mineral, administered through the federal mineral-leasing system rather than ordinary unpatented mining claims. That means Idaho's phosphate production does not show up anywhere in the claim counts on this page — a distinction worth understanding before assuming every commercially significant mineral activity in Idaho is claim-based.

Who Controls the Land and Minerals in Idaho?

BLM manages nearly 12 million acres of public surface land in Idaho and approximately 36.5 million acres of federal subsurface mineral estate. Those two figures describe different things: the larger mineral-estate acreage extends beneath land whose surface is managed or owned by someone else — the U.S. Forest Service, another federal agency, the State of Idaho, or a private landowner — not just beneath the 12 million acres of BLM-managed surface.

Seeing public land on a map does not, by itself, establish that the land is open to mineral entry.

Seeing no current claim does not mean the ground is available to stake.

Idaho State Land and Riverbeds Require Different Research

The Idaho Department of Lands (IDL) and the Idaho Land Board have statutory authority to administer mineral leasing on more than 3.4 million acres of state endowment trust land mineral estate. That land is managed for the benefit of Idaho's endowment beneficiaries (primarily public schools), under state leasing rules that are separate from BLM's federal mining-claim system.

Navigable Riverbeds

IDL states that Idaho owns the beds and banks of navigable waterways below the ordinary high-water mark, along with the mineral rights associated with those lands, and that IDL administers riverbed mineral leases and exploration locations.

This matters for prospectors because a river's surface appearance tells you nothing about who holds the mineral rights beneath it. A waterway that looks like ordinary public land can involve state-owned mineral rights subject to IDL leasing and exploration rules — and some waterways have restricted mineral entry. Staked Maps does not make a blanket statement that Idaho riverbeds are open or closed to mineral activity; check current IDL rules for the specific waterway before assuming recreational or commercial mineral activity is permitted.

Before You Dredge or Use Mechanized Mining Equipment in Idaho

Idaho DEQ's Small Suction Dredge General Permit (IDG370000) authorizes discharge from small suction dredges — intake nozzle 5 inches or less in diameter, engine 15 horsepower or less — into eligible waters, and requires operators to be working in a DEQ/EPA-designated open area. Separately, the Idaho Department of Water Resources (IDWR) requires its own Small Scale Mining Authorization for mechanized equipment — suction dredges, powered sluice boxes and high bankers — operating below the ordinary high-water mark, and maintains its own open/closed stream designations. IDWR notes that its open/closed designations and other agencies' designations for the same stream can differ, so a stream that is open under one program is not automatically open under the other — the operator is responsible for confirming both.

Special-area procedures exist beyond the general rules above — for example, IDWR maintains a separate supplemental process for the South Fork Clearwater River and a separate, seasonally limited permitting window for the McCoy Creek drainage. Do not assume the general rules above cover every Idaho stream.

A Verified Idaho Collecting Example: Emerald Creek Garnet Area

The Forest Service identifies the Emerald Creek Garnet Area, on the Idaho Panhandle National Forest, as a public collecting area for Idaho star garnets. Access is by advance reservation only through Recreation.gov — no tickets are sold on site — and the site operates seasonally, roughly Thursday through Saturday from Memorial Day weekend through Labor Day weekend.

This is a useful contrast for understanding the mineral-occurrence data later on this page:

• MRDS mineral occurrence: evidence that minerals were recorded at or near a location. It does not, by itself, establish a public right to collect there.
• Managed collecting area: a specific agency has established a public collecting opportunity, subject to its own rules, fees and schedule.

Collecting elsewhere on National Forest land is generally handled differently — wilderness areas, cultural or archaeological sites, and any existing mining claim are outside the ticketed Garnet Area program and can carry their own restrictions. Staked Maps has not independently verified access rules for every Idaho collecting location; check current Forest Service information before visiting.

Idaho Rockhounding & Mineral Occurrence Records

Staked Maps currently contains 7,243 documented Idaho mineral-occurrence / rockhounding research records derived from the USGS Mineral Resources Data System (MRDS) — 6,392 classified as metallic and 851 as non-metallic. USGS describes MRDS as records describing mineral deposits, mines, prospects and occurrences. That makes MRDS useful research data, but it does not establish public access or collecting legality at any given point.

How to Research an Idaho Prospecting Area Before You Go

1. Find the general area and inspect current mining claims. Start with Staked Maps' current federal claim layer to see what's already recorded nearby.

2. Add surface-management information. Layer in who manages the surface — BLM, U.S. Forest Service, State of Idaho or private — since that alone doesn't tell you who controls the minerals.

3. Examine historical claims and mineral-occurrence records for context. Prior claim activity and MRDS records can point to areas with a documented mining history, without proving current access or availability.

4. Check federal and state restrictions, mineral ownership and access. Confirm whether the area involves state endowment mineral rights, navigable riverbed mineral rights, withdrawals, or private property before assuming it's open.

5. Verify current legal status with the appropriate agency before staking or disturbing ground. BLM, IDL, Idaho DEQ or IDWR — depending on what you're researching — before you stake a claim, dredge, or otherwise disturb ground.

How Staked Maps Builds the Idaho Mining Claims Map

A useful mining map needs more than points and polygons. It also needs clear source provenance and an honest explanation of what each dataset can and cannot establish.

Current Mining Claims & Sites

Current federal mining claim and site records in Staked Maps originate from Bureau of Land Management mineral-record data, including the Mineral & Land Records System (MLRS). Staked Maps synchronizes current claim records daily — not in real time with every visit. The separate historical/closed-claims dataset is synchronized on a less frequent schedule.

Current / not-closed is a Staked Maps grouping. Individual BLM status values (Active, Filed, Under Review and others) are retained separately and shown in the status analysis above.

Historical / Closed Claims

Historical records represent claims and sites that are part of BLM's closed-claims dataset. They are useful because previous claim activity can reveal where mineral exploration occurred, but a historical claim does not prove that land is open today or that economically valuable minerals remain.

Mapped Claim Geometry

Staked Maps converts available federal land descriptions and source geometry into map features designed for research and field reference. Mapped claim polygons are not professional cadastral surveys and should not be treated as legal property-boundary determinations. Where exact legal position matters, review the official BLM record and appropriate survey information.

Surface Management & Land Ownership

Land-ownership and surface-management layers help you understand who manages the surface, but surface management alone does not determine mineral ownership or whether land is open to mineral entry. This distinction is especially important in Idaho, where BLM, U.S. Forest Service, State of Idaho, and private ownership of the surface and mineral estate frequently do not line up with each other.

Mineral Occurrences

Staked Maps' mineral-occurrence research layer is derived from the USGS Mineral Resources Data System. MRDS records document mineral occurrences, prospects, mines and reported commodities. They are not a curated list of legally accessible public rockhounding sites.

Idaho Geology & Regulatory Content

Idaho-specific geology and regulatory content on this page relies primarily on the U.S. Geological Survey, the Idaho Geological Survey, BLM, the Idaho Department of Lands, Idaho DEQ, IDWR and the U.S. Forest Service. Regulatory content is reviewed periodically, not continuously; see the dated review notes above each regulatory section.

What Staked Maps Does Not Determine

Staked Maps does not determine:

• whether land is legally open to mineral entry
• whether a valid mineral discovery exists
• mineral value or recoverability
• legal mineral ownership, including state endowment or riverbed mineral rights
• survey-grade claim boundaries
• legal access through private property
• permission to work another person's mining claim
• whether a specific activity requires DEQ, IDWR, BLM, USFS or IDL authorization
• whether a USGS MRDS location is publicly accessible
• whether minerals remain at a historical occurrence

Staked Maps is a research and navigation tool. For legal filings and final land-status decisions, verify the current official record with the responsible government agency.
