mining; mineral; museum; state history

HB 2264 establishes a mining, mineral, and natural resources educational museum at the University of Arizona and clarifies the Arizona Geological Survey's duties. The Geological Survey must map geology, maintain public databases of mineral resources, and provide accessible information to the public. The museum will collect mining artifacts, offer educational programs, and may charge admission fees while accepting donations. This bill directly affects the public (via free access to geologic data and museum exhibits), the University of Arizona (as operator), and Arizona's mining industry (through historical recognition).
