The below-ground stock of gold reserves is currently estimated to be around 50,000 tonnes, according to the US Geological Survey. To put that in perspective, around 190,000 tonnes of gold has been mined in total, although estimates do vary. Based on these rough figures, there is about 20% still to be mined.
Does the earth continuously make gold?
Gold sank to the Earth’s core during the planet’s formation. It’s only accessible today because of asteroid bombardment. Theoretically, it’s possible to form gold by the nuclear processes of fusion, fission, and radioactive decay.
Time flies doesn’t it! In real terms, it’ll probably take more than 20 years to deplete known reserves. As gold prices go up (which they inevitably will), recycling rates are likely to increase. On the other hand, as gold prices go up, rates of mine development and expansion will likely go up too.
Is gold still being formed?
Although gold deposits continue to form in active volcanic areas, greenstone belts and their gold deposits no longer form on Earth today. Examples include parts of Canada, Zimbabwe and Australia. 7. Placer deposits form at Earth’s surface when weathering action exposes gold from other, older lode deposits.
It can typically take between 10 and 20 years after a deposit is discovered before a gold mine is ready to produce material that can be refined into bullion.
Can you create gold?
Yes, gold can be created from other elements. But the process requires nuclear reactions, and is so expensive that you currently cannot make money by selling the gold that you create from other elements.

Can gold be man made?
Long answer: yes, it can be done with a bit of effort and spending a lot more money than gold is worth. To understand why this is even possible, one needs to be aware of how gold is created in nature. Repeating this process in a lab or controlled environment is certainly possible, but very costly.

Does ocean water contain gold?
Yes, there is gold in the ocean. Ocean waters do hold gold, but it’s difficult to say exactly how much. If you were hoping make your fortune mining the sea, consider this: Gold in the ocean is so dilute that its concentration is very small.
Can gold be destroyed?
Gold Can’t Be Destroyed, only Dissolved Pure gold is virtually indestructible. It will not corrode, rust or tarnish, and fire cannot destroy it. This is why all of the gold extracted from the earth is still melted, re-melted and used over and over again.

Is gold Actually scarce?
Gold is rare throughout the Universe because it’s a relatively hefty atom, consisting of 79 protons and 118 neutrons.
