Cash Cost

Cash cost is a commonly used (though non-standardized) financial metric in the mining industry that represents the total per-unit cost of producing a tonne of ore, concentrate, or refined metal — or per ounce in the case of precious metals — considering only those costs that require current cash outflows, thereby excluding non-cash charges such as depreciation, amortization, depletion, and impairments. In gold mining, cash cost per ounce (C1 cash cost and C2 cash cost) has historically been a widely reported industry metric, calculated under World Gold Council methodology and its successor standards. C1 cash cost typically includes all direct mining costs (drilling, blasting, loading, hauling), processing costs (crushing, grinding, leaching, refining), site administration and general expenses, and by-product credits (revenues from silver, copper, or other co-products that offset gold production costs), but excludes royalties, corporate-level costs, sustaining capital, and exploration expenditure. C2 (total cash cost) adds royalties and similar charges. In iron ore mining, cash cost per tonne of iron ore produced or shipped is a key benchmark metric that reflects the competitiveness of different producers on the global cost curve, encompassing mining, processing, dry-stack tailings management, corporate overheads, and port operations but typically excluding freight to customer. In bauxite mining, cash cost per tonne of bauxite extracted reflects the operational expense of dragline or truck-shovel mining, washing, crushing, and transport to port. Understanding cash cost positioning relative to the commodity price helps miners assess margin resilience during price downturns, guides production optimization decisions, and is central to mine planning and economic analysis. The All-In Sustaining Cost (AISC) framework introduced by the World Gold Council in 2013 has largely superseded simple cash cost reporting by gold miners, incorporating sustaining capital and other charges for greater transparency and comparability.
