Mining Claim Recordation (MCR)
1) A requirement of FLPMA that mining claimants notify, in writing, the proper BLM office of the location of unpatented mining claims. The notification takes the form of a copy of the county location notice or certificate, supplemented by name or number of the claim, name and current mailing address of the owner or owners of the claim, type of claim, date of location, a description of the location of the claim to closest 160-acre quadrant of a section; and a drawing of the claim plotted on a USGS topographic quadrangle map (or a sketch of the claim referring to some similar topographic base map). 2) An automated system that records the information required by FLPMA that mining claimants notify, in writing, the proper BLM office of the location of unpatented mining claims.
