A new metric has since been developed by the World Gold Council to report the "all-in sustaining costs" of mining gold. These numbers report that the cost of extracting an ounce of gold is actually over $1,000 per ounce, well above the aforementioned numbers. And since gold is currently trading at just over $1,200 per ounce, it explains why ...
Gold Mining Operation: 10 - 30 years. The gold mining operation stage represents the productive life of a gold mine, during which ore is extracted and processed into gold.
