2019 6 13 For the companies exploring for gold, a deposit that has more than one gram of gold for every tonne of earth is an exciting prospect. In fact, in our 2013 report summarizing the worlds gold deposits, we found that the average grade of gold deposits in the world is around that amount about 1.01 g/t.. Think about that for a moment.
So much gold has already been mined. Current estimates from the World Gold Council (WGC) suggest that around 187,200 tons of gold have already been mined, two thirds of which were mined in the last 70 years or so. Pack this gold together and youve got a cube that measures about 21 meters on each side.
2019 6 11 Mines and gold mining operations have become increasingly geographically diverse, far removed from the concentrated supply of four decades or so ago when the vast majority of the worlds gold came from South Africa. China was the largest gold producer in the world in 2016, accounting for around 14% of total annual production.
2019 6 13 Each year, global gold mining adds approximately 2,500 3,000 tonnes to the overall above ground stock of gold. While gold production has shown an upward trend in recent years, this is likely to level off in coming years. Accurately estimating the amount of gold still within the ground is no easy task, and this estimate may change in response to several factors, such as
To further add uncertainty to global gold production small scale miners do not typically report their take. This is especially true in third world countries. A lot of gold is mined in this way, primarily placer but hard rock as well. How much gold is left in the ground? Nobody really knows.
2 This statistic shows the annual global gold production in mines 2005 2018. In 2005, world gold production amounted to 2,470 metric tons. Since then, world gold production increased steadily up to
