43 CFR 3830.95 - What if I pay only part of the service charges, location fees, or first year maintenance fees for newly-recorded claims or sites?
(1) Assign serial numbers to each mining claim or site;
(3) Send a notice to you that you must pay any outstanding service charges as described in § 3830.94. For example, BLM will apply the money to cover the location and maintenance fees for as many mining claims or sites as possible. BLM will return any remaining certificates or notices for which we cannot apply full payment of location and maintenance fees. BLM will apply any remaining funds as service charges in serial number order until the money runs out. BLM will then notify you if you must pay any outstanding service charges for mining claims or sites for which you paid location and maintenance fees, as provided in § 3830.94.
(b) If you want to resubmit the new location notices or certificates that BLM returned to you, you must do so with the complete service charges, location fees and maintenance fees within 90 days of the original date of location of the claim or site as defined under state law, or you will forfeit the affected mining claims or sites.
