The Empire Mine alone operated until 1956. Today, active prospecting continues in the South Yuba and Bear River corridors under the suction dredge moratorium — dry sluicing and highbanking with non-motorized pumps remain legal on most federal waterways. The BLM Mother Lode Field Office in Folsom handles claim recording and surface management questions for this district.
