Gold dredge in Rhodesia
Hydrojet dredge with multiple pontoon hull is employed in winning gold-bearing sand and gravel in depths up to 30 ft; during tests its output is reported to have been 300 cu yd/hr in free-running sand, 210 cu yd/hr in free-getting gravel up to stone size of 7 in. sphere, and 62 cu yd/hr in gravel in crevices and between large rocks and boulders; craft is designed for dredging free-getting materials at considerably greater depths than conventional craft; 200 ft dredging depth is feasible.
