Peru's reserves lead the way (120, 000 metric tons). There are around 560,000 metric tons of silver reserves left around the world, the USGS reports. Peru's reserves top the list (120,000 metric tons), followed by Poland (100,000 metric tons), Australia's (90,000 metric tons) and Russia's (45,000 metric tons). Of the 1,740,000 metric tons of silver discovered to date, 55% is found in just four countries in the world.
All the silver discovered so far would fit in a cube measuring 55 meters on each side. The industry's most reliable estimates seem to agree that there are about 3 billion ounces of. Given the accessible industry data, it can be presumed that there are between 3 and 3.5 billion ounces of. Approximately ½ troy ounce per living human being.
The combination of geological data, aggregated mining and verifiable historical records from the World Gold Council shows that around 190,000 metric tons of gold and about 1.6 million tons of silver have been physically extracted throughout the history of the Earth's crust. If you wonder how much gold is left in the world to extract, it is estimated that there are still approximately 54,000 tons of gold ore underground. Silver and gold ore freshly extracted from silver and gold mines or deposits are further refined to obtain industrial goods, jewelry, silverware and ingot products suitable for investment (gold ingots, gold coins and privately minted cartridges). Much can also be deduced from the historical data of gold mining companies and from the standard percentages of physical production of silver and gold (industrial) compared to almost 198,000 metric tons of gold that have been extracted over time, according to the World Gold Council, compared to nearly 1.74 million metric tons of silver.
