§526 Mining and Leasing Act operations

Title 30 › Chapter CHAPTER 12— - MULTIPLE MINERAL DEVELOPMENT OF THE SAME TRACTS › § 526

Last updated Apr 6, 2026|Official source

Summary

When the same land is used for both mining and mineral leasing, each activity must be done so it fits with the other as much as reasonably possible. Mining must try to avoid harming any known deposits of minerals reserved for leasing. Leasing must try to avoid harming any known deposits that belong to the miner. Both types of work must also avoid endangering or seriously interfering with any surface or underground improvements, workings, or facilities the other party has built or uses. If a court finds that one use cannot be stopped without causing worse harm than allowing it, the court can let that use go ahead. The court may require payment or a security deposit as fair compensation for the damage caused. Either party can ask the other to provide, at the requester’s cost, any maps or survey information they have about where improvements or workings are. The owner must also allow the requester to inspect those places at reasonable times, and at the requester’s risk. If someone refuses to give the information or access and damage follows, the requester is not liable for that damage. A refusal only costs the refusing party court costs and lawyer fees if a court forces them to comply. The maps and surveys provided are only what the party already has and are not promised to be perfectly accurate.

Mineral Lands and Mining — Source: USLM XML via OLRC

(a)Where the same lands are being utilized for mining operations and Leasing Act operations, each of such operations shall be conducted, so far as reasonably practicable, in a manner compatible with such multiple use.
(b)Any mining operations pursuant to rights under any unpatented or patented mining claim or millsite which shall be subject to a reservation to the United States of Leasing Act minerals as provided in this chapter, shall be conducted, so far as reasonably practicable, in a manner which will avoid damage to any known deposit of any Leasing Act mineral. Subject to the provisions of subsection (d) of this section, mining operations shall be so conducted as not to endanger or materially interfere with any existing surface or underground improvements, workings, or facilities which may have been made for the purpose of Leasing Act operations, or with the utilization of such improvements, workings, or facilities.
(c)Any Leasing Act operations on lands covered by an unpatented or patented mining claim or millsite which shall be subject to a reservation to the United States of Leasing Act minerals as provided in this chapter shall be conducted, so far as reasonably practicable, in a manner which will avoid damage to any known deposit of any mineral not so reserved from such mining claim or millsite. Subject to the provisions of subsection (d) of this section, Leasing Act operations shall be so conducted as not to endanger or materially interfere with any existing surface or underground improvements, workings, or facilities which may have been made for the purpose of mining operations, or with the utilization of such improvements, workings, or facilities.
(d)If, upon petition of either the mining operator or the Leasing Act operator, any court of competent jurisdiction shall find that a particular use in connection with one of such operations cannot be reasonably and properly conducted without endangering or materially interfering with the then existing improvements, workings, or facilities of the other of such operations or with the utilization thereof, and shall find that under the conditions and circumstances, as they then appear, the injury or damage which would result from denial of such particular use would outweigh the injury or damage which would result to such then existing improvements, workings, or facilities or from interference with the utilization thereof if that particular use were allowed, then and in such event such court may permit such use upon payment (or upon furnishing of security determined by the court to be adequate to secure payment) to the party or parties who would be thus injured or damaged, of an amount to be fixed by the court as constituting fair compensation for the then reasonably contemplated injury or damage which would result to such then existing improvements, workings, or facilities or from interference with the utilization thereof by reason of the allowance of such particular use.
(e)Where the same lands are being utilized for mining operations and Leasing Act operations, then upon request of the party conducting either of said operations, the party conducting the other of said operations shall furnish to and at the expense of such requesting party copies of any information which said other party may have, as to the situs of any improvements, workings, or facilities theretofore made upon such lands, and upon like request, shall permit such requesting party, at the risk of such requesting party, to have access at reasonable times to any such improvements, workings, or facilities for the purpose of surveying and checking or determining the situs thereof. If damage to or material interference with a party’s improvements, workings, facilities, or with the utilization thereof shall result from such party’s failure, after request, to so furnish to the requesting party such information or from denial of such access, such failure or denial shall relieve the requesting party of any liability for the damage or interference resulting by reason of such failure or denial. Failure of a party to furnish requested information or access shall not impose upon such party any liability to the requesting party other than for such costs of court and attorney’s fees as may be allowed to the requesting party in enforcing by court action the obligations of this section as to the furnishing of information and access. The obligation hereunder of any party to furnish requested information shall be limited to map and survey information then available to such party with respect to the situs of improvements, workings, and facilities and the furnishing thereof shall not be deemed to constitute any representation as to the accuracy of such information.
