How to Verify a Mining Claim Before You Buy
Essential due diligence steps to protect your investment and avoid common pitfalls

Purchasing a gold mining claim is an exciting investment, but it also comes with significant risks if proper verification isn't conducted. Unlike traditional real estate, mining claims have unique legal requirements and potential complications. This guide will walk you through the essential steps to verify a mining claim before finalizing your purchase.
Why Verification Is Critical
Mining claim verification isn't just a good idea—it's essential protection against potentially costly mistakes. Without proper verification, you risk:
- Purchasing an invalid or abandoned claim
- Discovering boundary disputes with neighboring claims
- Finding undisclosed restrictions on mining activities
- Learning about access issues or easement problems
- Uncovering environmental liabilities or violations
Step 1: Verify the Claim's Status with the BLM
The Bureau of Land Management (BLM) maintains records of all mining claims on federal lands. Start your verification process here:
- Check LR2000 Database: The BLM's Land & Mineral Legacy Rehost System (LR2000) contains records of all active mining claims. Search using the claim name, serial number, or township/range/section information.
- Verify Annual Maintenance: Confirm that all annual maintenance fees have been paid. Claims with unpaid fees may be subject to forfeiture.
- Check Claim Type and Size: Verify whether it's a placer or lode claim and confirm the acreage matches what the seller is advertising.
- Review Filing History: Look for any gaps in the claim's history that might indicate periods when it was invalid or abandoned.
Pro Tip: BLM Office Visit
While the LR2000 database is helpful, nothing beats an in-person visit to the local BLM office. Staff can help you access the complete claim file, including the original location notice, which often contains crucial details not available online.
Step 2: County Recorder's Office Verification
Mining claims must be recorded both with the BLM and the county where the claim is located. At the county recorder's office:
- Verify the Claim Recording: Ensure the claim is properly recorded in the county records.
- Check for Assessment Work: Some counties require proof of annual assessment work (though this has largely been replaced by the BLM maintenance fee).
- Review Chain of Ownership: Trace the claim's ownership history to ensure there are no gaps or competing ownership claims.
- Check for Liens or Encumbrances: Verify there are no liens, judgments, or other encumbrances against the claim.
Step 3: Physical Boundary Verification
Don't rely solely on paperwork—verify the physical aspects of the claim:
- Locate Corner Monuments: Mining claims should have corner monuments marking their boundaries. Verify these exist and match the description in the location notice.
- Check for Overlapping Claims: Use the BLM's GeoCommunicator maps or Mining Claim Activity Maps to check for potential overlaps with other claims.
- Verify Access Routes: Confirm legal access to the claim. Some claims may be surrounded by private property or have seasonal access limitations.
- Document with GPS: Use GPS to record the corner locations and compare them with the legal description.

Step 4: Environmental and Regulatory Review
Mining claims come with environmental responsibilities and regulatory requirements:
- Check for Environmental Issues: Look for any existing environmental violations, contamination, or cleanup requirements.
- Review Local Regulations: Some counties have additional requirements or restrictions on mining activities.
- Verify Water Rights: If the claim's value depends on water access, verify any associated water rights or permits.
- Check for Special Designations: Verify whether the claim is within any special management areas (wilderness, conservation areas, etc.) that might restrict mining activities.
Step 5: Verify the Seller's Authority to Transfer
Ensure the seller has clear title and authority to transfer the claim:
- Confirm Ownership: Verify that the seller is the recorded owner of the claim.
- Check for Co-owners: If there are multiple owners, ensure all are participating in the sale or have authorized it.
- Review Operating Agreements: If the claim is held by a company or partnership, review any operating agreements that might affect the transfer.
- Verify Corporate Status: If the seller is a corporation or LLC, verify its good standing with the Secretary of State.
Step 6: Conduct Due Diligence on the Claim's Value
Beyond legal verification, assess whether the claim is worth the asking price:
- Request Production Records: Ask for documentation of gold recovered from the claim.
- Conduct Test Sampling: If possible, do your own sampling to verify gold presence.
- Research Historical Production: Check historical records for the area's production history.
- Compare Similar Claims: Research recent sales of similar claims to ensure the price is reasonable.
Red Flags to Watch For
- Sellers who resist providing documentation or BLM serial numbers
- Claims with unusually low prices compared to the market
- Vague or changing descriptions of the claim's location or boundaries
- Pressure tactics urging you to buy quickly without proper verification
- Reluctance to allow physical inspection of the claim
- Extraordinary claims about gold production without documentation
Step 7: Get Professional Help When Needed
For significant investments, consider professional assistance:
- Mining Attorney: An attorney specializing in mining law can review documents and identify potential issues.
- Land Surveyor: A professional surveyor can accurately determine claim boundaries.
- Mining Consultant: An experienced consultant can evaluate the claim's mineral potential.
- Title Company: Some title companies offer limited services for mining claims.
Conclusion
Thorough verification is essential when purchasing a mining claim. While it requires time and effort, proper due diligence protects your investment and helps ensure you're getting what you pay for. Remember that a legitimate seller should welcome your verification efforts—resistance to providing information or documentation is often a warning sign.
