Understand Dredging Basics
If you’re out to mine some buried treasure, you need to learn about the concept of dredging. It’s considered perhaps the most effective method of small scale prospecting, and it’s gaining in popularity.
Simply put, dredging involves using a suction dredge to vacuum gravel from the bottom of a creek bed. Usually, a dredge is a sluice box affixed to a four-legged stand or positioned on floats. An engine pump is then either mounted on the floats with the sluice box or positioned on shore. High pressure water flows from the pump through a hose to a jet tube or power jet nozzle. Using the simple principle of suction, you are able to bring in gravel, rocks, and gold.
