How much gold there is
Estimates put all the gold ever mined at a little over 200,000 tonnes, and because gold does not corrode, almost all of it still exists. Mines add roughly 3,600 tonnes a year, a small fraction of that total, which is part of why gold’s supply is described as stable.
Fewer big discoveries
The industry has found fewer large new gold deposits in recent decades than it did in the past, despite significant spending on exploration. The easiest deposits to find, close to the surface and in accessible places, have largely been found.
Lower ore grades
In many established mines, the amount of gold in each tonne of rock has fallen over time. Lower grades mean moving and processing more rock to produce the same amount of gold, which pushes up costs and energy use.
Years from discovery to production
Taking a gold deposit from discovery to a working mine commonly takes more than a decade, and often around fifteen years, once exploration, feasibility studies, financing, permitting and construction are counted. That means a higher gold price today cannot quickly produce more gold.
Rising costs and pressures
- Energy and labour costs feed directly into the cost of each ounce.
- Environmental and social standards rightly demand more of new projects.
- Political risk in some producing countries can delay or halt development.
Recycling fills part of the gap
Recycled gold, mostly from old jewellery, adds well over a thousand tonnes a year, and tends to rise when prices are high. It helps balance the market but cannot replace new mine supply entirely.
What it means for buyers
Constrained supply does not guarantee higher prices, because demand can fall too. But it is one reason many people regard gold as a scarce, long term store of value. See why gold prices rise and fall.
Questions people ask
How much gold is mined each year?
Roughly 3,600 tonnes.
How long does it take to open a gold mine?
Commonly more than a decade from discovery to production.
Will gold run out?
Almost all gold ever mined still exists above ground, but new supply is becoming harder and more costly to find.
