RE:RE:RE:Cash Costs about $900 oz.Unfortunately AISC is not fully defined in the accounting profession as each industry has many complexities and issues that are open to interpretation. The world gold council simply encourages member miners to estimate thier AISC as best as is possible to be transparent to shareholders about the true nature of that company's ability to show a bottom line profit on an ongoing basis until the mine is closed and the earth restored..
So each miner has leeway in how they come up with AISC as there is no regulatory body they have to answer to on this matter. In AR's case, considering how much the scope of the project had to be changed....dams etc to protect wildlife and so on, I have no confidence in thier declaration of AISC and I suspect down the road it will be evident to be much higher
