Most articles about California mining claims are written to sell one. This page is not. Below we lay out what a claim is under federal law, how a real one is located and recorded in 2026, what it costs each year, and how the market for buying claims is riddled with worthless offers. The point is to leave you able to read a claim advertisement and know within two minutes whether it is worth another look.

The federal statute at the heart of everything is the Mining Law of 1872, codified at 30 USC sections 22 to 54. The federal regulations that carry it into practice sit at 43 CFR parts 3800 to 3838. California layers county-level recording rules on top through Public Resources Code sections 2301 and 2304. Nothing here is legal advice; the citations are so you can read the primary source when you need to.

What a mining claim actually is

An unpatented mining claim is a right of possession, not title. The Bureau of Land Management defines it as "a parcel of land for which the claimant has asserted a right of possession and the right to develop and extract a discovered, valuable, mineral deposit." That right does not include exclusive surface rights. The United States retains the land itself.

This distinction is not a technicality. The Surface Resources Act of 1955 (Public Law 84-167, codified at 30 USC 611 to 615) confirmed that on claims located after July 23, 1955, the surface stays open for public use, including grazing permits and recreation. You cannot fence off your claim to keep hikers out, and you cannot build a permanent residence on it just because you hold it.

The right of possession is also conditional. It exists only as long as the claim is properly located, timely recorded, and kept in good standing every year through either the annual maintenance fee or a valid waiver. Miss one filing deadline and the claim is treated as abandoned by law.

Which land in California can be claimed

Only federal public land that is currently open to mineral entry can be located as a mining claim. In California that is mostly ground managed by the Bureau of Land Management and by the US Forest Service. Everything else is off limits.

Closed to mineral entry in California:

• All national parks and national preserves: Yosemite, Sequoia and Kings Canyon, Death Valley, Redwood, Joshua Tree, Lassen Volcanic, Pinnacles, Channel Islands, Mojave, Point Reyes.
• All wilderness areas designated after the Wilderness Act signing on September 3, 1964 (16 USC 1133); after February 3, 1988 the closure is total, per the Wilderness Act sunset provision.
• Areas withdrawn under the Federal Land Policy and Management Act (FLPMA) or specific presidential proclamations. Many national monuments in California, including Berryessa Snow Mountain and Carrizo Plain, are withdrawn.
• Wild and Scenic River corridors, most Indian trust land, and lands acquired by the United States after passage of the Weeks Act of 1911 unless later opened.
• All state, county, and private land: the Mining Law of 1872 does not apply to non-federal ground.

Before you spend an hour on the ground, use the BLM Mineral and Land Records System (MLRS) at mlrs.blm.gov to check the parcel. MLRS shows active claims, closed areas, and public-domain status for the specific township, range, and section. It is the same tool BLM caseworkers use.

Lode claims, placer claims, mill sites, tunnel sites

The Mining Law recognizes four kinds of location on federal ground. Two of them (lode and placer) are used to hold the mineral itself. The other two (mill sites and tunnel sites) support operations on a nearby claim.

Lode claims cover deposits in rock in place, such as the gold-bearing quartz veins that made the Mother Lode famous. Federal statute at 30 USC 23 caps a lode claim at 1,500 feet in length and 600 feet in width, with 300 feet allowed on either side of the vein. Descriptions run by metes and bounds from the discovery point.

Placer claims cover minerals concentrated by weathering: the flakes and small nuggets carried by rivers into gravel bars and old streambeds. Under 30 USC 35, a placer claim cannot exceed 20 acres per individual locator. An association of eight or more people can locate a single placer claim up to 160 acres, but a corporation is capped at 20 acres per claim and cannot be part of an association placer.

Mill sites (30 USC 42) support a lode or placer operation with a mill or reduction works. They must sit on non-mineral ground, be noncontiguous to the parent claim, and cannot exceed 5 acres. Tunnel sites (30 USC 27) reserve a 3,000-foot subsurface right of way to reach blind lodes not yet discovered on the surface.

Locating a claim on the ground

Federal law requires an actual discovery of a valuable mineral before a claim exists. This is not paperwork alone. Courts have held under the "prudent person" test that a reasonable person, with knowledge of the facts, would have to be justified in the further expenditure of time and money to develop the deposit. Post-your-corners-and-file is not enough; the mineral has to be there.

California adds ground-marking rules on top of the federal standard. Public Resources Code section 2301 requires a claimant to post a location notice at the discovery point and mark the claim's corners with substantial monuments. Acceptable monuments include a wooden post at least four inches square set two feet in the ground, or a stone of similar size. The location notice must show the claimant's name, the date of location, and a description sufficient to identify the claim.

Lode claims are marked by their end lines, side lines, and discovery point. Placer claims, where practicable, are located by legal subdivision (aliquot part of a section) instead of metes and bounds. Overlapping an existing valid claim is void as to the overlap. Overlapping a withdrawn area is void entirely.

Recording with the county and with BLM

Recording is a two-step process, and both steps have 90-day windows counted from the date of location. Skipping either step voids the claim.

Step 1: county recorder

California Public Resources Code section 2304 requires a copy of the notice or certificate of location to be recorded with the recorder of the county where the claim sits, within 90 days of location. Each Gold Country county maintains a mining-claim book. Recorder fees are set by county and typically run in the low tens of dollars per document.

Step 2: BLM California State Office

The Federal Land Policy and Management Act of 1976 (43 USC 1744) requires the claimant to file a copy of the county-recorded document with the BLM within 90 days of location. That filing must include the location fee, the initial maintenance fee, and the applicable processing fee under 43 CFR 3000.12. Filings in California go to the BLM California State Office in Sacramento.

Failure to file with BLM within 90 days is deemed abandonment as a matter of federal law: BLM does not take a discretionary position on this. The clock is the clock.

The current fees and what they buy you

Three fees apply the first year, then one recurring fee applies every year after. All amounts below reflect the final BLM rule adjusting fees for the Consumer Price Index, published at 89 Federal Register 54364 on July 1, 2024. That rule is the fee schedule now in effect.

The one-time location fee is 49 dollars per claim, mill site, or tunnel site (43 CFR 3830.21). It funds administrative processing when the claim is first recorded with BLM.

The initial maintenance fee, also 200 dollars, covers the assessment year in which the claim is located. It is paid at the same time as the location fee. Placer claims pay 200 dollars per 20 acres or portion of 20 acres, so a 60-acre association placer pays 600 dollars.

The recurring annual maintenance fee is 200 dollars per claim (or per 20-acre placer subdivision), due on or before September 1 each year, and covers the assessment year that begins the following day. Miss the September 1 deadline and the claim is void by operation of law.

A separate processing fee at 43 CFR 3000.12 covers each specific filing action (notice of location, transfer of interest, amendment, and so on). Processing fees are adjusted annually and typically run in the low tens of dollars per action. BLM publishes the current schedule in the Federal Register each fiscal year.

How the annual fee has moved since 1993

The annual maintenance fee is not a fixed number. Section 10101 of the Omnibus Budget Reconciliation Act of 1993 (30 USC 28f) directed the Secretary of the Interior to adjust the location and maintenance fees for changes in the Consumer Price Index at least every five years. The most recent adjustment took the fee from 165 dollars to 200 dollars starting July 1, 2024.

The pattern matters for anyone who buys a claim expecting stable carrying cost. The fee doubled between 1993 and 2024, and the next CPI window closes December 31, 2028. A holder of 10 claims paid 1,000 dollars a year in the 1990s and pays 2,000 dollars a year now, before any processing fees or county filings.

The small miner waiver at 43 CFR 3835

Congress recognized that CPI-indexed fees would price out hobby prospectors. The workaround is a statutory exemption from the annual maintenance fee, codified at 43 CFR part 3835. The small miner waiver is the most common route in California for recreational claim holders.

You qualify if you and all related parties, taken together, hold no more than 10 unpatented mining claims or sites nationwide. Every co-claimant must independently qualify. Instead of paying the fee, you agree to perform at least 100 dollars of assessment work per claim per year under 30 USC 28. That is labor or improvements that advance development: prospecting drifts, sample pits, road maintenance to the claim, and so on. Bare presence on the claim does not count.

You must file BLM's waiver certification form on or before September 1 for the assessment year you want covered, per 43 CFR 3835.10. The form lists every claim by BLM serial number and requires original signatures of all claimants. An affidavit of assessment work performed then follows during the next assessment year. Missing either deadline defaults the claim to the standard fee (and if that is not paid, void).

Mineral patents and the ongoing moratorium

Historically, a claimant who could prove discovery and had performed 500 dollars of improvements on a lode claim could apply for a mineral patent under 30 USC 29. Patenting converted the claim into deeded private land at a nominal price (2.50 dollars per acre for placer, 5.00 dollars per acre for lode). California's Gold Country is dotted with old patented parcels dating to the late 19th and early 20th centuries.

New patents have not been available since the mid-1990s. Every Department of the Interior appropriations act since fiscal year 1994 has included a rider prohibiting BLM from using funds to process patent applications filed after September 30, 1994. Congress has renewed the moratorium every year since, and the Biden and Trump administrations have both continued it. BLM will only work applications grandfathered under the moratorium.

The practical result: if someone offers you a "patented mining claim," you are being offered private deeded land, subject to normal county property tax and real estate transfer rules. If someone offers you an unpatented mining claim, no patent path exists to convert it, and you will hold nothing more than a right of possession subject to annual fees.

Buying a claim: the scam surface

Mining claims are transferable. Assignment of an unpatented claim is done by quitclaim deed recorded with the county recorder, then a transfer notice filed with BLM per 43 CFR 3833.30. There is a live market for claims on eBay, on regional forums, and through claim-broker websites. Much of what is offered is worthless. Some of it is fraudulent.

The Federal Trade Commission has warned for decades about mineral-investment fraud. Its consumer alert Investment Opportunities in Mining Ventures identifies inflated ore assays, misrepresented deposit values, and phantom claims as recurring patterns. Recent FTC enforcement in adjacent categories (precious-metals investment schemes) has continued to target sellers who blur the line between claim ownership and gold ownership.

The most common problems with claims offered for sale to the general public:

• Worked out or barren ground. Many advertised claims sit on ground picked over by dredges and drift mines a century ago. The remaining gold is often below what a hobby operator can recover economically.
• Missing or expired filings. The seller may have skipped the September 1 fee or the FLPMA filing. The claim is void by law but is still listed as active in seller advertising.
• Closed ground. The claim may be on land withdrawn from mineral entry after the original location (wilderness expansion, monument proclamation). The seller does not always disclose this.
• Bad chain of title. The seller may not actually hold the claim: a prior transfer may not have been filed with BLM, or the claim may be co-owned by a party who has not signed.
• Confusing "leases" of claims. Some sellers rent access to a claim for a season fee. Access rentals are not ownership, and the rental agreement often disclaims any duty to maintain the claim's federal status.

Before you send money to buy a claim, run three checks. First, look up the BLM serial number in the MLRS system at mlrs.blm.gov and confirm the claim status is active and all filings are current. Second, pull the county recorder's book and page number for the most recent location certificate and every recorded transfer, and confirm the seller is in the current chain of title.

Third, walk the ground with the seller and verify the physical corner monuments match the recorded description. Any seller who cannot show a BLM case-file number or refuses a site visit is a hard pass.

Respecting other people's claims while prospecting

Most recreational gold hunting in California happens without staking a claim: hand-panning under the BLM casual-use rule at 43 CFR 3809.5, supervised panning at a state park, or on private ground with the owner's permission. In every case, respect for existing claims is both a legal obligation and a safety issue.

Federal law treats an active claim as the exclusive possessory right of the holder. Entering the claim to prospect or take minerals without the claimant's written permission is trespass on the possessory interest, actionable in state court, and can also expose you to federal charges if you take minerals. This applies even if the claim is unfenced and unposted: the BLM MLRS record is public notice.

Before you drop a pan in a stream on public land, check MLRS for active claims covering that section. If a claim exists, either move upstream or downstream off the claim, or knock on the door of the listed claimant to ask permission. Verbal permission from someone at a nearby camp is not enough; get it in writing. A polite ask is often granted for hand-tool panning, but you will not know without one.

The California Department of Conservation and the California Council of Rock and Mineral Clubs also publish maps of open ground. County sheriff's offices in Gold Country counties routinely respond to claim-jumping calls, some of them armed encounters. This is not a hypothetical risk. Read the ground, read the records, and stay off active claims.

When staking a claim is a bad idea

For most recreational gold hunters, a claim is unnecessary and often counter-productive. If you plan to work a specific stretch of stream a few weekends a year with a pan and a small sluice, BLM casual-use rules already permit that on unclaimed public ground, without a filing, a fee, or annual maintenance. Staking would trade a free legal right for a 249 dollar year-one bill plus 200 dollars every September thereafter.

Staking is also not a way to acquire land. The right of possession does not include exclusive surface use, so you cannot build a cabin, close off the ground, or exclude other members of the public from recreating on the claim. Any impression that a mining claim is a back-door path to owning federal ground is wrong under current law, and the patent moratorium closes even the historic route.

Staking makes sense in a narrow set of cases. You need a real prospect on ground that is open to entry, samples that satisfy the prudent-person test, budget for the annual fee (or waiver eligibility), and a plan to work the claim in a way that develops the deposit. Absent those facts, the paperwork is a cost with no benefit.

If your interest in gold is really about owning it rather than digging it, that is a different question with a different answer. You can find our general reference on owning physical gold in California without touching a claim.

People also ask

Does a mining claim give me title to the land?

No. An unpatented mining claim grants the right of possession to the minerals in the claim and the right to extract them. It does not give you title to the surface. Public Law 84-167 (the Surface Resources Act of 1955) reserved surface uses to the United States on all claims located after July 23, 1955. Sources: BLM Locatable Minerals page and 30 USC 611 to 615.

How much does a gold mining claim cost per year?

As of the current BLM fee schedule effective July 1, 2024, the annual maintenance fee is 200 dollars per lode claim, mill site, or tunnel site, plus 200 dollars per 20 acres of a placer claim. There is also a one-time 49 dollar location fee and a processing fee per 43 CFR 3000.12 when the claim is first recorded. Fees are adjusted for the Consumer Price Index every five years. Source: 89 FR 54364 (July 1, 2024).

Can I mine on somebody else's claim if they are not there?

No. An active claim gives the holder the exclusive possessory right to the minerals on that ground. Entering an active claim to prospect or take minerals is trespass under state and federal law, even if the claimant is absent. Casual-use panning on unclaimed BLM land is allowed under 43 CFR 3809.5, but you must first verify with the BLM Mineral and Land Records System (MLRS) that the ground is not already claimed.

Are gold mining claims for sale a good buy?

Almost always, no. The FTC has long warned that mineral-property investments sold to the general public are frequently misrepresented. Many claims offered on online marketplaces are worked out, in closed ground, or in default on the annual fee. Verify status in the BLM MLRS system and the county recorder before any purchase. Sources: FTC Consumer Alert Investment Opportunities in Mining Ventures and BLM MLRS.

Where in California can I actually locate a claim?

Only on federal public domain lands open to mineral entry, most of them managed by the Bureau of Land Management or the US Forest Service. National parks (Yosemite, Sequoia and Kings Canyon, Death Valley, Redwood, Joshua Tree, Lassen, Pinnacles) are closed to mineral entry. Wilderness areas designated after February 3, 1988 are also closed. Withdrawn areas around wild and scenic rivers, some national monuments, and Indian trust land are closed. Source: BLM California State Office and 16 USC 1133.

Do I have to record with the county AND with BLM?

Yes. California Public Resources Code section 2304 requires you to record a copy of the location certificate with the county recorder within 90 days of location. FLPMA (43 USC 1744) then requires you to file the county-recorded document with the BLM California State Office within 90 days of location. Failure to file with BLM within 90 days is deemed abandonment of the claim as a matter of federal law.

What is the small miner waiver?

A statutory exemption from the annual maintenance fee, codified at 43 CFR 3835. It is open to claimants who, together with all related parties, hold no more than 10 unpatented mining claims or sites nationwide. Instead of paying the fee, waiver holders must perform at least 100 dollars in assessment work per claim per year under 30 USC 28 and file the waiver certification form with BLM on or before September 1. Source: 43 CFR 3835.1 and 3835.10.

Can I still get a patent that turns my claim into private land?

Not in practice. Congress has renewed a moratorium on new mineral patent applications every year since fiscal year 1994 in the Interior Department appropriations act. BLM will process patents already grandfathered before the moratorium, but no new patent applications are being accepted. Source: BLM Locatable Minerals Patents page.
