Your first payment comes sooner than most people expect. Assessment years run September 1 to September 1, and the maintenance fee you pay at recording covers the assessment year you located the claim in — the one already running (43 CFR 3834.11). So the next payment is due on the first September 1 after your date of location, not a year later. Stake in July, and your first annual deadline is that same September.
Two paths to keep your claim alive each year:
Path A — Pay the Fee
$200 per lode claim or $200 per 20 acres (or portion) per placer claim. Pay online via MLRS or mail/walk-in to the BLM Portland State Office. Due on or before September 1 each year. When Sept 1 falls on a weekend/holiday, BLM publishes the effective date.
Then record an affidavit of the fee payment with the county within 30 days of paying (ORS 517.210 — a fee-paid year needs its own county affidavit too).
Path B — Small Miner Waiver
If you hold ≤10 claims nationwide (including related parties — spouses, partners, co-locators):
- File BLM Form 3830-002 by Sept 1 (no fee). Form 3830-002 PDF
- Do $100+ assessment work per claim during the assessment year (12:01 a.m. Sept 1 through the close of Aug 31, 30 U.S.C. § 28).
- Record the affidavit with the county within 30 days of completing the work (ORS 517.210 — every year, whichever path you took).
- File a copy with BLM by December 30 (+$15/claim). Optional federal form: Form 3830-004.
The claim’s year of location is different. If a Small Miner Waiver covers the assessment year you located the claim in, the December 30 BLM filing for that year is a Notice of Intent to Hold ($15 per claim), not the affidavit of assessment work (43 CFR 3835.31(c); contents, 43 CFR 3835.33; the $15 fee, 43 CFR 3830.21). From the next year on, a waiver year’s December 30 filing is the affidavit (Form 3830-004). This site does not prepare the Notice of Intent to Hold — ask the BLM state office what it needs to show.
The Annual Assessment Work tool fills out this affidavit for you today and tracks the December 30 BLM deadline.
Other lifecycle filings: Transfer of interest — record deed at county, then file with BLM, $15/claim/transferee. Amended location notice — county first, then BLM, $15/claim.
