FLPMA requires you to record all mining claims and sites with BLM and the local recording office in order to maintain a mining claim or site under the General Mining Law.

(a) If you fail to record a mining claim or site with the BLM and the local recording office by the 90th day after the date of location, it is abandoned and void by operation of law.

(b) Recording a mining claim or site, filing any other documents with BLM, or paying fees or service charges, as this part requires, does not make a claim or site valid if it not otherwise valid under applicable law.
