Rising Use of New AISC Measure of Gold Production Costs


(Mining) – Use of the “all-in maintaining costs” (AISC) measure of gold output is increasing, as it supplies a more comprehensive look at costs than the traditional “cash cost” approach.

The AISC assess, finalized in June and sustained powerfully by the World Gold assembly, includes other costs such as general office spending and capital used in mine development and output to conceive a benchmark of a company’s functioning efficiency.

Terry Heymann of the WGC said “The economics of gold mining have not been as well understood as they could be by a broad variety of persons encompassing governments, groups and even employees,”

Goldcorp was amidst the first to adjust its describing measures, doing so at the starting of 2013. The company’s 2013 cash costs were outlook at $525 to $575 per ounce, and all-in sustaining cash charges were $1,000 to $1,100.

Profits accounts from some of the other large-scale gold businesses indicate an AISC of between $1,200 – $1,400/ounce, the economic Times accounts. In some situations AISC has even crept up over $1,400.

Barrick recently described an AISC of $919, very much on the lower end of the AISC spectrum.

Goldfields checked in at $1,280/ounce and African Barrick was up high at $1,416/ounce.

Not all are in favour of the new assessing, although Randgold CEO Mark Bristow called the measure irrelevant, pointing out that business could get away with reporting “positive margins between sales cost per ounce of production…yet, because of write-downs or impairments, still register losses.”
