Mining Methods

The Gold Rush period was dominated by placer mining for gold. It was not until hard rock or deep mining spread that other metals, along with gold, were mined. Placer mining refers to mining for gold that nature has freed from its associated rock and left in the form of nuggets, flakes, grains, or dust.

Gold and gold mining

Gold mining was rough, physical work. Where alluvial gold was very rich, it could be obtained with a shovel and pan. However, pans were used mainly for prospecting. Simple machines known as cradles (often made from wooden liquor boxes) were rocked back and forth – the heavier gold collecting on matting on the cradle base.
