U.S. DEPARTMENT OF THE INTERIORBUREAU OF LAND MANAGEMENT
Rock collecting and gold panning are generally permitted on public lands, except for certain designated areas, such as wilderness areas, Wilderness Study Areas, developed special management areas or recreation sites. Precious and semi-precious gems can be collected in reasonable quantities without a permit, as long as the activity is for personal use and not commercial purposes.
While gold panning and non-mechanized sluicing are unregulated on most public lands, dredging and mechanized sluicing are regulated and may require a permit. To ensure the enjoyment of all visitors on public lands, please follow all necessary laws, regulations and guidelines:
Various other regulations also apply. For additional information, contact the local BLM Field Office for the area you are planning to visit.
