Abstract: A circular tray having an upper surface shaped to incline downwardly from a center to an outer circumference. The tray including annular grooves for collecting gold. A crank is connected to the tray for rotating the tray. The tray is supported with a stand having at least one elongate arm extending radially across the tray above the tray in spaced apart relation thereto. Multiple loops of a line material are attached in spaced apart depending relation along the elongate arm in such a way that the bottom portion of the loop extends in a direction which is oblique with the elongate arm. Each loop is sized to have the bottom portion resting in close proximity with the upper surface of the tray so that when the tray is rotated, the loops mechanically move ore across the surface of the tray from the center to the outer periphery.
