Mining and Iron Ore context

In the mining industry, Hematite is a type of iron ore — a very high-grade form (Fe₂O₃) with a high iron content (~60–70% iron).

• C1 cost (sometimes called “Cash Cost C1”) is a cost metric used in mining.
• C1 measures the direct production costs per ton of ore or metal produced (including mining, processing, and administrative costs but excluding things like depreciation, exploration, interest, etc.).

So “Hematite C1” probably refers to:

The cash production cost (C1) of hematite iron ore.

This is a key number for mining companies and investors — it shows how cheap or expensive it is for a company to produce iron ore.
