The deepest gold mine in the World is TauTona Mine in South Africa which reaches 3.9 kilometers below ground. The TauTona mine, operated by AngloGold Ashanti, is a gold mine so its a good yard stick for how deep we can go. The volume of the earth (approximated as a sphere) is 1,086,832,411,937 cubic kilometres.
At what depth is gold found?
There is no specific depth at which gold can be found. Examples of this are the Welcome Stranger – the largest gold nugget ever found – which was retrieved at only 3cm (1.18in) below the surface. Oppositely, gold mining operations today take place at a depth of around 3km (1.8 miles) under the Earth's surface.

How do you know if there is gold in the ground?

Where is gold most likely to be found?
Gold is primarily found as the pure, native metal. Sylvanite and calaverite are gold-bearing minerals. Gold is usually found embedded in quartz veins, or placer stream gravel. It is mined in South Africa, the USA (Nevada, Alaska), Russia, Australia and Canada.

Can metal detector detect gold?
One of the most common questions we get is Does The Metal Detector Detect Gold? The answer is YES, they all do. Some do it better than others. Some detectors like the Minelab Gold Monster or GPZ 7000 are specifically designed to find small gold pieces (which most naturally occurring gold is).

One study found there is only about one gram of gold for every 100 million metric tons of ocean water in the Atlantic and north Pacific. There is also (undissolved) gold in/on the seafloor. The ocean, however, is deep, meaning that gold deposits are a mile or two underwater.
How much gold is left unmined?
The below-ground stock of gold reserves is currently estimated to be around 50,000 tonnes, according to the US Geological Survey.

Gold is found on the surface, while copper is found at depth
The first, which are very deep, promote the mineralisation of the copper over a long period, while the latter, which are closer to the surface, produce more gold.

Is there gold in every stream?
In most cases, the creeks and rivers that flow through mining areas will indeed have some gold in them. However, the amount will vary considerably depending on many factors. The gold in rivers is called “placer gold” and it is the process of erosion that has caused it to accumulate there.

How can you tell a rock is gold?
You're looking for a scratch on the glass. If the glass gets scratched from the 'gold', it's not actually gold.
