http://www.bloomberg.com/news/2014-11-05/plunging-gold-price-has-mining-companies-selling-at-loss.html Lists the Barrick all-in cash cost at $834. This would be an average of all production. I believe that the low cost providers will likely increase production during this time as it will create long term profitability even if the short term drives gold price down due to more supply) (Kill your competitors in the blood bath that their own debt causes) As we discussed before, expect high cost production facilities to eventually be idled. This should counter the coming ramp up from the low cost producers.
