Aug 26, 1938 – A gold recovery plant has been established east of Minot near the Mouse River by the Herman Hanson Syndicate. Soil travels up a conveyor belt to a circular drum. There it is washed and whirled. The coarse gravel is discarded and the finer material, carrying the gold content passes across a vibrating screen, which sifts the material even finer. Water pumped from the river, washes the screened material down into sluices where a series of riffles and special cloths trap the gold. The concentrate is then pit through a special electro-amalgamated process, which extracts the gold dust. Between 2,000 and 3,000 cubic yards of material will run through the plant daily.
