Eneabba Project

Sheffield’s Eneabba Project, located about 110km north of Perth, contains seven mineral sands deposits: West Mine North, Ellengail, Yandanooka, Durack, Drummond Crossing, Thomsons and Robbs Cross. The Project is located near existing mineral sands operations and a network of highways and railway lines connecting to the Geraldton and Fremantle/Kwinana ports. Sheffield’s strategy is to accumulate deposits capable of supporting a sequential mining operation with a flexible mobile plant. 

In the March 2018 quarter, maiden Mineral Resource estimates incorporating results from exploration drilling were completed at the Robbs Cross and Thomsons HMS deposits.  At Robbs Cross, immediately north of the Drummond Crossing deposit, total Mineral Resources comprising 17.8 million tonnes @ 1.9% heavy mineral (HM) above a 1.4% HM cut-off (Indicated and Inferred) have been estimated.

At Thomsons, total Mineral Resources comprising 26 million tonnes @ 2.0% heavy mineral (HM) above a 1.4% HM cut-off (Inferred) have been estimated.  Both deposits occur at or near-surface and have high proportions of valuable heavy minerals (VHM) in the assemblage, with high components of zircon and rutile (see Sheffield's Quarterly Activities Report for the Period ended 31 December 2017 for details).

The addition of Robbs Cross and Thomsons brings total Mineral Resources for the Enabba HMS Project to over 7.6 million tonnes of contained HM (Measured, Indicated and Inferred) in seven deposits, including 897kt of zircon, 540kt of rutile, 323kt of leucoxene and 4,703kt of ilmenite (see Appendix 1 for a complete listing of Sheffield's Resources and Reserves).

Review work has commenced on Mineral Resources for Yandanooka, Durack, Drummond Crossing, West Mine North and Ellengail to enable reporting under the JORC Code (2012)
