GAP YEAR EXPOSURE

In 2011, Congress accidentally broke the maintenance fee statute for pre-1993 lode mining claims. For one assessment year, thousands of claims lost the legal protection that excused them from FLPMA annual filings — and most claimants never knew. The gap was fixed in 2013, but the fix was prospective only. No retroactive cure was ever enacted. Claims that were exposed remain exposed. And claim jumpers are actively datamining BLM records to find them.

What Happened

Why This Matters Now

The Supreme Court confirmed in United States v. Locke (471 U.S. 84, 1985) that FLPMA's forfeiture provision operates automatically with no equitable exceptions — not for good faith, not for government error, not even when a BLM employee provided incorrect advice about the filing deadline. The forfeiture is conclusive by statute.

This means a third party — a claim jumper — could potentially relocate over an "abandoned" claim by arguing the original holder's failure to file a FLPMA annual filing during the gap year triggered automatic forfeiture. The question has never been squarely litigated, but the statutory text is unambiguous.

Claim jumpers are actively datamining BLM MLRS records to identify these vulnerable claims. They are looking for the same pattern ClaimWatch identifies: pre-1993 lode claims that paid the AY2013 fee but have no FLPMA filing on record. The difference is that ClaimWatch has already run the analysis across the entire federal claim database, and we can tell you whether your specific claims are at risk.

What the Report Covers

• Exposure classification — Each claim is classified as EXPOSED (no qualifying FLPMA filing found) or PROTECTED (qualifying filing on record with BLM) based on BLM serial register data.
• Claim-by-claim detail — Case serial number, claimant name, location date, claim type, county, state, maintenance fee payment record, and FLPMA filing status for each affected claim.
• Per-claimant rollup — Total exposed and protected claims by claimant, so operators with large portfolios can see aggregate risk at a glance.
• Filing code breakdown — For protected claims, which type of FLPMA filing was made (Affidavit of Assessment Work, Notice of Intent to Hold, or other qualifying instruments).
• Methodology supplement — Full documentation of the legal basis, identification criteria, data sources, and known limitations. Built for attorney review.

Which Claims Are Affected

• Lode claims located before August 10, 1993
• Mill sites located before August 10, 1993
• Tunnel sites located before August 10, 1993

Placer claims are not affected. The 2011 amendment retained "before, on, or after" coverage for placers in paragraph (a)(2).

Only claims that paid the AY2013 maintenance fee but did not file a qualifying FLPMA Section 314(a) annual filing by December 30, 2012 are classified as exposed.

Who Needs This Report

• Mining companies holding pre-1993 lode claims who need to know whether their ground is vulnerable to claim jumping or third-party relocation.
• Individual claimants who located claims before 1993 and want to understand their exposure before it becomes a problem.
• Mineral title attorneys preparing opinions of title or advising on claim validity who need a data-driven exposure analysis to support their assessment.
• Acquirers and investors evaluating a claim portfolio who need to know whether any target claims carry gap year forfeiture risk.
• Land departments managing large claim portfolios who need to identify and triage exposed positions across multiple states.

Data Sources

• BLM MLRS serial register — Maintenance fee payment records (action codes 782, 482, 682, 582, 6902) and FLPMA annual filing records (action codes 480, 481, 6912, 4802).
• BLM claim records — Location dates, claim types, case serial numbers, and claimant data from the MLRS claims module.
• Statutory authority — 43 U.S.C. §1744 (FLPMA Section 314), 30 U.S.C. §28f-28i (maintenance fee system), Pub. L. 112-74 §430, Pub. L. 113-6 §1403.
