Defects or other problems that cannot be cured and therefore result in forfeiture of your mining claims or sites are:

(a) Failing to record a mining claim or site within 90 days after you locate it;

(b) Failing to pay the location fee or initial maintenance fee within 90 days after you locate it; and

(c) Locating a mining claim or site on lands withdrawn from mineral entry at the time you locate it.

Even if you record your transfer or amendment with the local recording office, BLM will not recognize the interest you acquire, or send you notice of any BLM action, decision, or contest, regarding the mining claim or site until you file the transfer with BLM (see § 1810.2 of this chapter). The Department will treat the last owner of record as the responsible party for maintaining the mining claim or site until you file a transfer notice. You cannot claim that BLM failed to give you notice of any BLM action, decision, or contest regarding a mining claim or site if you failed to file a transfer notice showing that you have an interest in the mining claim or site, before BLM took the action, made the decision, or issued a contest complaint.
