A sluice support for positionally supporting a sluice box within a waterway provides an anchor post, an axially and rotatably movable slide hammer and two adjustably positionable support frames releasably engageable with the slide hammer to adjustably support a sluice box within a waterway.

A flow regulation system includes a sluice box that may be positioned adjacent to a fluid source. The sluice box may have a fluid urged therethrough. A regulator is slidably attached to the sluice box such that the regulator selectively restricts a flow of the fluid through the sluice box. The regulator resists being urged by the fluid flowing through the sluice box.

A sluice box is described comprising two walls, and a plurality of riffles. Riffles can have a first portion that extends below the bottom panel of a sluice box (or the bottom of a flow), and a second portion that extends above the bottom panel of a sluice box (or the bottom of a flow). By creating a catch in a riffle by having a portion of the riffle extend below a bottom panel of a sluice box, heavier minerals are not washed away as quickly, if at all, as with other sluices.

A hopper assembly for accepting placer deposit and water for use with a highbanker includes a hopper and a cover. The hopper includes an intake surface for accepting the placer deposit, a hopper periphery portion extending along a periphery of the hopper, a water intake, and a window configured to allow the placer deposit and water to exit from the hopper. The water intake accepts water and is located within the hopper periphery portion. The cover includes a cover surface and a plurality of cover openings. The cover surface fits over the hopper periphery portion. The cover openings are formed on the cover surface. The cover surface and the hopper periphery portion define, at least in part, a hollow within which water from the water intake flows. The cover openings allow for water to exit the hollow and contact the placer deposit on the intake surface.
