And so, while Mnangagwa and his so-called adviser claim they are “rehabilitating the Mazowe River,” what is actually taking place is called gold sluicing. Common in artisanal and small-scale mining, especially along rivers. Widely practiced in parts of Asia, and South America. Gold sluicing is a traditional method of extracting gold from alluvial deposits—gold that has been eroded from rock and deposited in riverbeds, streams, and floodplains. The process involves using sacking material such as burlap, gunny sacks, old feed bags, or coarse netting as matting to trap gold particles. Gold-bearing soil, sand, and gravel are fed into a sluice channel. Through gravity separation, the heavier gold settles at the bottom while lighter material is washed away. The riffles and gunny-sack mats trap the dense gold particles and allow lighter debris to pass through. The trapped gold is then periodically collected from the sacks. Only the gullible and the uninformed ana Mutisi can be deceived by this charade.
