Mining Claim Staking Requirements 2025: Complete BLM Compliance Guide

Staking a mining claim on federal land is the first critical step in securing mineral rights for exploration and development. The process is regulated by the Bureau of Land Management (BLM) under the General Mining Law of 1872, with specific requirements for location, monumentation, and filing. Miss a deadline, improperly mark your claim, or file incomplete paperwork, and your claim could be invalidated—costing you valuable time and mineral rights.

Types of Mining Claims

There are three basic types of minerals on federally-administered lands: locatable, leasable, and salable. Mining claims are staked for locatable minerals, which include both metallic minerals (gold, silver, lead, copper, zinc, uranium) and nonmetallic minerals (fluorspar, asbestos, mica).

Lode Claims

Lode claims are for deposits that include classic veins or lodes having well-defined boundaries. They also include other rock in-place bearing valuable minerals, including broad zones of mineralized rock. Examples include quartz veins bearing gold and large-volume, low-grade disseminated gold deposits.

Size limits: A lode claim can be a maximum of 1,500 feet parallel to the vein and 600 feet perpendicular to the vein or outcrop. The maximum area is 20 acres per claim.

Placer Claims

Placer claims cover "all forms of deposit, excepting veins of quartz, or other rock in-place." In practical terms, every deposit not located with a lode claim should be appropriated by a placer location. These typically include alluvial (stream-deposited) gold and other loose mineral deposits.

Size limits: Placer claims are located by legal subdivision where practicable. Maximum size is 20 acres per individual locator. Association placer claims can include up to 160 acres for 8 or more locators. Corporations may locate 20-acre claims but cannot locate association placers unless in partnership with other locators.

Where You Can Stake Claims

You can stake claims on BLM-managed lands in the following states: Alaska, Arizona, California, Colorado, Idaho, Montana, Nevada, New Mexico, Oregon, South Dakota, Utah, Washington, and Wyoming—plus portions of Arkansas, Florida, Louisiana, Mississippi, Nebraska, and North Dakota.

All BLM land is generally open to prospecting, except for reclamation projects, land being evaluated for wilderness potential, national parks and monuments (withdrawn in 1976), and other specifically withdrawn areas. Always verify land status at BLM.gov before staking.

Physical Staking Requirements

Federal law specifies that claim boundaries must be distinctly and clearly marked to be readily identifiable. You must stake and monument the corners of your mining claim using methods that meet applicable state requirements and size limitations.

When staking a claim:

• Place location posts or rock monuments at each corner of the claim
• Post a location notice in a conspicuous place on the claim
• The location notice must include: date of location, locator's name, claim name, type of claim, acreage claimed, and legal description of the parcel

2024-2025 Fee Updates

Federal statute requires the BLM to adjust mining claim fees every five years to reflect changes in the Consumer Price Index. As of September 1, 2024, fees have increased:

Location Fees

• Location fee increased from $40 to $49 per claim
• Applies to all claims located on or after September 1, 2024

Annual Maintenance Fees

• Maintenance fee increased from $165 to $200 per claim
• For lode claims, mill sites, and tunnel sites: $200 per claim or site
• For placer claims: $200 for every 20 acres (a 40-acre placer = $400; a 45-acre placer = $600)
• Due on or before September 1 each year for the upcoming assessment year

Maintenance Fee Waiver

To qualify for a maintenance fee waiver, each claimant and all related parties must hold 10 or fewer claims nationwide. Waiver claimants must instead perform and document annual assessment work.

Filing Requirements Summary

1. County filing: File location certificate with the county recorder within the state-specified deadline (typically 30-90 days)
2. BLM filing: Submit BLM Form 3830-1 to the appropriate State Office within 90 days of county filing
3. Initial fees: Pay location fee ($49) and initial maintenance fee ($200) with BLM filing
4. Annual maintenance: Pay maintenance fees by September 1 each year, or file proof of assessment work if claiming a waiver

Common Mistakes to Avoid

• Late filings: Missing the 90-day deadline results in automatic claim abandonment under federal law
• Improper monumentation: Failing to properly mark corners or post required notices
• Wrong land status: Attempting to stake on withdrawn, reserved, or already-claimed land
• Incomplete paperwork: Missing required information on location certificates
• Missed maintenance fees: Failing to pay by the September 1 deadline or file waiver documentation
• Overlapping claims: Locating boundaries that conflict with existing valid claims
