Hydraulic Mining Methods

All methods required water and because of that they could only be used during the summer. Panning for gold was the simplest method of recovering gold, but mostly used for prospecting since it was slow.

Early Gold Mining Methods . Miners during the early Gold Rush years wanted only one thing: gold. They didn’t care about elegance, craft or aesthetics.
