Process more gold-bearing material without hauling a full-size highbanker into the field. The GeoSluice California Mini High Banker combines a lightweight nine-pound design with adjustable legs, an adjustable spray bar, and GeoSluice’s efficient drop-riffle recovery system.
The compact design is easy to transport, set up, operate, and clean. It is an excellent choice for creek prospecting, remote locations, concentrate processing, sampling, and recirculating setups where portability matters.
Weighing approximately nine pounds with the stand and pump, the California Mini High Banker delivers a useful balance of portability and processing capability. Its compact size makes it easier to carry into locations where a larger highbanker would be difficult to transport.
The adjustable legs help establish the correct sluice angle on uneven ground, while the adjustable upper section lets you fine-tune the spray-bar position and water action for the material being processed.
The molded drop-riffle sluice uses gravity and water flow to separate heavier gold from lighter sand and gravel. The recessed riffles create low-pressure capture zones that allow gold to settle while lighter material continues through the sluice.
Unlike traditional carpet-and-expanded-metal systems, the molded drop-riffle design has fewer loose components to remove during cleanup. This makes inspecting and rinsing captured material faster and more convenient.

Successful highbanking depends on establishing the correct relationship between water flow, sluice angle, material size, and feed rate. The adjustable legs allow the sluice angle to be changed, while the adjustable spray bar helps direct water into the hopper.
Begin with a moderate slope and feed material gradually. Adjust the angle and water flow until lighter material clears the sluice while black sand and other heavy material remain active in the drop-riffle capture zones.
When processing is complete:
Stop the pump and allow the water to drain.
Remove the spray bar if needed.
Carefully rinse the drop-riffle sluice into a cleanup pan or container.
Pan or process the recovered concentrates to separate the gold.
The molded drop-riffle design eliminates the need to remove and clean traditional carpet, expanded metal, and individual riffle components.
