Part of the guide: Quarterly results explained: a complete guide to reading Indian company results
ExplainersHow metals and mining companies report results: realisation, volume and cost explained
A metals or mining company's results turn on volume, price realisation and cost per tonne, not just revenue. What these terms mean, how they separate the commodity cycle from the company's own performance, with an illustrative example.
For a manufacturer, revenue mainly moves with how much it sells. For a metals or mining company, revenue moves with two things that are reported separately: how much it produced and sold, and the price it realised for it — and that second number is often set by a global commodity market the company does not control. Reading a metals or mining result means separating the two.
Volume: what was produced and sold
- Production (or output): the quantity mined, smelted or refined in the period, usually in tonnes (or lakh tonnes for larger volumes). For a miner this may be reported at more than one stage — ore mined, and the refined metal produced from it.
- Sales volume: the quantity actually sold in the period, which can differ from production if inventory builds up or draws down.
- Capacity utilisation: production as a share of the plant or mine’s rated capacity. A period of low utilisation (maintenance, a shutdown, an approvals delay) explains a volume swing on its own, separate from demand or price.
Realisation: the price side
- Realisation (or “average realised price”): the average price per tonne the company actually received, which can differ from the benchmark market price because of contract terms, product mix, or hedging.
- Because base-metal and mineral prices are set on exchanges or by global benchmarks, a swing in realisation often reflects the commodity cycle rather than anything the company did differently. A results commentary that separates “higher realisation” from “higher volume” is telling you which of the two moved.
Cost per tonne
- Cost of production per tonne: mining, processing and overheads divided by the tonnes produced. Comparing this across quarters shows whether the company’s own operations got more or less efficient, independent of the price it sold at.
- EBITDA per tonne or EBITDA margin: operating profit before depreciation, interest and tax, shown either as an absolute amount per tonne or as a share of revenue. Because both revenue and cost move with volume, EBITDA margin is a common way to compare periods of very different volume on a like-for-like basis.
An illustrative example
A fictional miner, for one quarter, against the same quarter a year earlier:
| This year | Last year | Change | |
|---|---|---|---|
| Sales volume (tonnes) | 12,000 | 10,000 | +20.0% |
| Realisation (₹/tonne) | 7,00,000 | 6,00,000 | +16.7% |
| Revenue (₹ crore) | 840 | 600 | +40.0% |
| Cost of production (₹/tonne) | 4,50,000 | 4,80,000 | −6.3% |
| EBITDA (₹ crore) | 300 | 120 | +150.0% |
| EBITDA margin | 35.7% | 20.0% | — |
Here, revenue rose partly because more was sold and partly because the price realised was higher — and cost per tonne fell at the same time, so EBITDA rose by much more than either volume or price alone would suggest. A results statement that gives all four lines (volume, realisation, cost, EBITDA) lets a reader see how much of the change came from the market and how much from the company.
Non-metal miners and processors
Coal, iron ore and other mineral producers report the same shape of figures — production and sales in tonnes, realisation per tonne, and cost per tonne — though the specific price benchmark and cost drivers differ by mineral. Read the company’s own presentation for how it defines each term, since practice varies between companies.
