Cost Accounting in Mining

Feb 15, 2017  Moreover, if such a record shows that the cost of mining is high, does it in any way enable the manager to put his finger on the leakage ? Does it necessarily follow that a mine which makes a profit of, say, 40 per cent, on 25-dollar ore, is doing less economical mining than one which saves 60 per cent, on 80-dollar ore ?

The true cost of producing an ounce of gold Provident

May 23, 2017  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.
