Apparatus for recovering metallic particles in a sub-surface formation includes first and second ducts that extend downwardly, the first duct discharging water in a pressurized stream to effect differential elevation of particles in a turbulant water zone. The second duct has an intake positioned for drawing water and particles into the second duct from that zone. A loose flexible connection interconnects the two ducts to accommodate second duct movement up and down and laterally relative to the first duct. Also provided is means to adjust the position of the second duct intake relative to the discharge of the first duct, and a carrier vehicle movable over terrain and water and suspending the two ducts.
