Dragline Gold Dredging

CIM Bulletin, 1945

IN 1932, Horace Onyett at Oroville, California, built a practical floating washing plant along the general lines as now known, using a 24 in. by 12 ft. trammel; it was fed with a1/2 yard dragline bucket, rated then at 200 yards per day. Onyett dubbed his plant a 'Doodlebug' . which name has clung to this type of operation ever since.
