(b) Operations to confirm discovery. The authorized officer shall authorize those mineral operations that may be necessary for the purpose of gathering information to confirm or otherwise demonstrate the discovery of a valuable mineral deposit consistent with the definition in paragraph (a) of this section or to obtain evidence for a contest hearing regarding the claim's validity, upon receipt of a proposed plan of operations as defined in § 292.63 of this subpart to conduct such operations and of sufficient information from the operator to show an exposure of valuable minerals on a claim that predates the withdrawal of the federal land from the operation of the United States mining laws. The authorized officer shall authorize only those operations that may be necessary to confirm or demonstrate the discovery of a valuable mineral deposit prior to the date of withdrawal of the federal land on which the claim is situated. Pursuant to this paragraph, the authorized officer shall not authorize any operations which would constitute prospecting, exploration, or otherwise uncovering or discovering a valuable mineral deposit.
