A new metric has since been developed by the World Gold Council to report the "allin 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
