Operations at the Jack Hills mine commenced late 2006. Mining operations ceased in 2012 and the Jack Hills mine was placed in a partial care and maintenance phase. Crosslands Resources Pty Ltd (the Licence Holder) is currently undertaking demobilisation and rehabilitation of the mine site.
In 2011, SRK completed a Bankable Feasibility Study for the Jack Hills Expansion Project. |

The Jack Hills Iron Ore Project is located on mining tenement M20/506 and lies within the Beringarra and Judal pastoral leases.
Crosslands Resources Pty Ltd (the Licence Holder) operates an open pit iron ore mine with an ore beneficiation plant, Class II putrescible landfill and a sewage treatment plant on mining tenement M20/50.
In late 2019, Mitsubishi Corporation (MC) sold 100% of Crosslands Resources Pty Ltd (CRL) shares, which was held by MC's wholly owned subsidiary Mitsubishi Development Pty Ltd, to Sinosteel unit Sinosteel Ocean Capital Pty Ltd.
Sinosteel Midwest Corporation Ltd. is a subsidiary of Sinosteel Ocean Capital Pty Ltd.
Summary:
The Jack Hills Resource comprises banded iron formation (BIF-BFO) of 2,870 Mt at 30.7 % Fe, Massive Iron Mineralisation (MIM), Direct Shipping material (MIM-DSO) of 133 Mt at 56.2 % Fe, Massive Iron Mineralisation potential Jig Feed or BFO (MIM-JIG) of 96 Mt at 45.5 % Fe and Detrital Iron Deposits (DID) which includes potential BFO, Jig feed canga or colluvium deposits of 118 Mt at 32.6 % Fe.
Summary:
Conventional large-scale truck and shovel mining method.
The JHEP mine plan, which has a projected life of 39 years, envisages a high-volume strip mining method utilising large-scale mining fleet at multiple working faces to produce a consistent quality of ore feed for the processing plant, with an average life of mine strip ratio of approximately 0.94:1.

Summary:
The plant design incorporates established equipment and processing technologies used domestically and internationally within the iron ore and other extractive industries.
Each concentrator module will utilise conventional low-intensity magnetic separation to produce a premium magnetite pellet feed concentrate and a gravity / flotation circuit to produce a high quality hematite sinter feed concentrate. Pilot testing of the flowsheet achieved total iron recovery of 74.8%.
