Small-scale gold mining is, for the most part, confined to these areas, since most operators lack the requisite mechanized equipment to mine hardrock deposits of the Birimian and Tarkwian Belts. The rivers and waterways highlighted on the map contain the
ceased. This form of mining usually involves the extraction of secondary gold from placer deposits alluvial, colluvial or elluvial, which can be liberated and treated using gravity methods. In the Guianas, the most popular form of small-scale gold mining is referred to as land dredging, a combination of hydraulicking and suction dredging.

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 rivers flow slows down on a large scale during a major flood storm.
