Methods of mining – Te Ara Encyclopedia of New Zealand
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.

It Started With An Idea | New Gold Recovery
Present day placer mining uses pans, water and gravity, just like the prospector of 1849, only on a larger scale. This “modern” placer technology only recovers up to 40% of the gold from every ton of ore concentrate (finely ground ore) as it primarily targets nuggets and flakes of gold. The remaining 60% goes untouched.
