Production commenced in late 2011 at the Extension Hill deposit which yielded over 15Mt of iron ore by the time reserves were depleted in late 2016. Production then switched to the nearby Iron Hill deposit in early 2017, yielding an additional 5Mt of DSO iron ore by the time final sales were completed in February 2019. Sales of stockpiled low grade material from Extension Hill are expected to be concluded in late 2019, after which the Mid West business will transition to final closure. |
Summary:
The Project is a combined hematite and magnetite open cut mining operation. Hematite ore and magnetite bearing Banded Iron Formation (BIF).
Summary:
The Project is a combined hematite and magnetite open cut mining operation. Hematite ore and magnetite bearing Banded Iron Formation (BIF) will be mined by conventional open cut methods of blasting and excavation with material loaded onto trucks and transported to stockpile areas.
Summary:
The hematite is direct shipping grade ore and no processing of the ore is required other than the crushing and screening of the ore into fines (<6.3mm) and lump (6.3 – 32.0mm).
Ore is mined, crushed and screened on-site, transported by sealed road 85km to Perenjori, where it is loaded onto rail wagons and railed 240km to the Geraldton Port. Mining commenced at Extension Hill in the 2011/12 financial year.
