Gold deposits along the general gold path can be small or large, depending upon the size of the gold trap. The most important type of gold trap in river mining is called the “pay-streak”. Pay-streaks always form along the gold path where the river’s flow slows down on a large scale during a major flood storm.

2.5" Dredge. This machine was a trend setter when it first came on the market and it continues to be one of our best sellers many years later. When other 2.5" dredges were floating on inner-tubes, required a suction nozzle for producing dredge vacuum, and had limited depth capabilities, the Proline 2.5" dredge sat on sturdy pontoons and used a power jet for dredge vacuum.
