Document Description
Mr. Phillip Osborn proposes to excavate underwater riverbed material along or near the thalweg (the line of lowest elevation) of the Klamath River for the exploration and recovery of gold between July 1 and September 30 of each calendar year. River bottom material will be hand excavated using a pick, shovel and pry bar to assess riverbed material for gold content on a floating work platform. Excavated riverbed material will be sampled and assessed on the floating platform using gold pans and sluice box. If the samples yield gold, paydirt will be processed on shore using a sluice box. At no time will the riverbed material be collected by the use of a suction dredge hose and nozzle, nor will the use of any motorized vacuum or suction device be used as part of the instream mining operation.
