revise certain mining statutes.

HB 1273 revises definitions and clarifies rules for "life of the mine permits" in South Dakota's mining law. It specifically defines how mining operators can temporarily pause operations (up to 180 days with notice) and extend pauses up to 10 years total, provided they submit plans for resuming work and maintain reclamation measures. This affects mining companies operating under these permits and the Board of Minerals and Environment, which oversees the process. The bill focuses on procedural clarity for permit management without introducing new environmental or financial requirements.
