The ore body is too deep to mine profitably by open pit. The grades or quality of the orebody are high enough to cover costs. Underground mining has a lower ground footprint than open pit mining. What is underground mining? The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining.

To produce 1 ton of DRI, we use 1.35 tons of iron ore raw materials, 400 m3 of natural gas and spend extra US$50-70.
