    May 23, 2017 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 mining companies have had

    OK, so what are the gold production costs and how can we use them in investing? The all-in sustaining costs were about $950 in 2017. It means that the price of gold was higher than the costs, making gold mining profitable. And the obvious investment implication is to invest in gold mining companies that do well in keeping all-in sustaining costs low
