I am an amateur prospector- and panning for placer gold (gold dust) suits me. It requires very little in the way of equipment, is fun, and gives you a great reason to spend a quiet Saturday on the river. However, large commercial mining companies mine gold in a very different way- drilling and blasting rock that is crushed, and the gold refined chemically. The Homestake Mine had shafts nearly 8000 feet deep before it closed.
Placer mining
Hardrock or Placer?
Gold mining typically involves both surface mining and underground mining. Initially, surface mining techniques such as panning, sluicing, and dredging are used to extract gold from shallow deposits. As the easier-to-access gold becomes depleted, underground mining methods like shaft mining and drift mining are employed to access deeper ore deposits.

The term "long tom" was for a type of very long sluice box used to separate [lacer gold from the base rock.
Open-pit mining is a type of surface mining where large quantities of material are excavated from a large, open pit. It is commonly used to extract minerals such as copper, gold, and coal.
The safest and cheapest type of mining is surface mining.
