The Snaefell magnetite deposit is part of IMX's Mt Woods Iron Project in South Australia. The deposit is located 12km southwest of the Cairn Hill mine and only 3km east of the sealed Stuart Highway.
A JORC (2004) classified Inferred mineral resource of 569Mt tonnes @ 27% Fe (using 18% Fe cut-off) has been estimated for Snaefell, making it the largest single resource in IMX's current iron portfolio. It is defined over a 2.7 km strike length which remains open along strike and at depth.
Snaefell is a magnetite-quartz hosted iron deposit characterised by a coarse grainsize that makes it amenable to upgrading through magnetic processes. Results of metallurgical testwork to date are extremely positive. Davis Tube Recovery (DTR) tests produced magnetic concentrates of 65% Fe at a coarse grind size of 200 μm with very low levels of impurities. This coarse, high grade concentrate will be suitable as direct feed to ironmaking sinter plants negating the need to pelletise this material.
High mass yields to a first stage dry magnetic concentrate at coarse crushing sizes are also achievable. These results indicate the potential to exploit this resource utilising a smaller than typical processing facility requiring significantly lower overall water and power inputs relative to other existing magnetite processing flowsheets.
