Abbreviation
AISC
Parent term

The All In Sustaining Cost (AISC) is a mining metric that estimates all direct and recurring costs required to mine a unit of ore.

World Gold Council Notes on AISC
The “all-in sustaining costs” is an extension of existing “cash cost” metrics and incorporate costs related to sustaining production. The “all-in costs” includes additional costs which reflect the varying costs of producing gold over the life-cycle of a mine. It is up to individual companies to determine how they report to the market and to decide whether their stakeholders will find these new metrics of value in understanding their businesses; it is expected that, since many companies report on a calendar year basis, they may choose to use these metrics from 1 January 2014.
