The true cost of producing an ounce of gold Provident

 · 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 mining companies have had less-than-stellar profits. Determining the costs of mining largely depend on the region as well.
