BLM issues the mineral use authorizations listed below to qualified individuals. Some authorizations are not available for certain commodities. See the subparts referenced in each subsection for more information. (a) ``Prospecting permits'' let you explore for leasable mineral deposits on lands where BLM has determined that prospecting is needed to determine the existence of a valuable deposit. See subpart 3505 of this part. (b) ``Exploration licenses'' let you explore in areas with known deposits of a leasable mineral to obtain data. With an exploration license, you do not get any preference or other right to a lease. See subpart 3506 of this part. (c) ``Preference right leases'' are issued to holders of prospecting permits who, during the term of the permit, demonstrate the discovery of a valuable deposit of the leasable mineral for which BLM issued the permit. There are other requirements. The requirements for mine plans are in subpart 3592 of part 3590 of this chapter. See subpart 3507 of this part. (d) ``Competitive leases'' are issued by competitive bidding for known deposits of a leasable mineral. See subpart 3508 of this part. (e) ``Fringe acreage leases'' are issued noncompetitively for known deposits of leasable minerals on Federal lands adjacent to existing deposits, when the Federal deposits can be mined only as part of an adjacent operation. See subpart 3510 of this part. (f) ``Lease modifications'' add acreage containing known deposits of a leasable mineral to an adjacent Federal lease of the same mineral, provided the deposits can be mined only as part of the larger mining operation. See subpart 3510 of this part. [[Page 655]] (g) ``Use permits'' are available to holders of phosphate and sodium leases so that they may use the surface of unappropriated and unentered public lands for the proper extraction, treatment, or removal of the phosphate or sodium deposits. See subpart 3516 of this part.
