I found this article interesting, especially where it discusses the rising production costs of several of the larger mining corporations. An analyst quoted in an article calculates all-in, sustaining costs of producing gold at around $1,100 an ounce on average for the mining industry.
Tumbling gold prices add to miners' miseries
http://www.theglobeandmail.com/repo...cle11228030/Anybody on CCF have knowledge of the mining industry and their production costs? I would expect that these costs would vary greatly from mine to mine due to varying labor costs, methods of extraction, and regulatory burdens.
