Mining Methods

Shaft Mining-when gold started to become scarce,miners began digging holes or shafts in the ground just below the surface.The shafts were approximately 1 metre squared and could be 50 metres deep.They would prop timber along the sides of the shaft to stop it from collapsing and would use a windlass or a winch to bring up buckets of soil.There needed to be a minimum of three to four miners

Alluvial Gold Mining

Alluvial Gold Mining. Alluvial gold is found beneath the surface at the bottom of a creak or stream.
