Revise laws regarding mining leases on state lands

This bill updates Montana laws governing mining leases on state-owned lands, primarily affecting mining companies and the state Board of Land and Mineral Resources. It establishes minimum lease terms of at least 10 years for both metallic minerals and nonmetallic minerals, with extensions tied to production or legal challenges. The legislation also restricts public access to certain geological information for a minimum of five years after lease expiration and allows lease modifications through agreement between the board and lessees.
