West Mine North

West Mine North is situated immediately along strike to the north of Iluka’s Eneabba West mine, just 6km from Eneabba, and is essentially a continuation of the high-grade strand mineralisation that was mined at Eneabba West in the 1990s.  The heavy mineral is associated with strandline and dunal deposition that trends northward towards Sheffield’s Ellengail deposit.  The project lies wholly within cleared freehold land on three granted Mining Leases: M70/965, M70/1153 and M70/872.

On 01 October 2018 West Mine North Mineral Resource estimate was revised to be compliant with JORC 2012 Reporting Code. West Mine North (applying a 2.0% HM cut-off) has a Mineral Resource of 12.0Mt @ 6.6% HM, with an indicated component of 10.2Mt @ 7.3% HM and an inferred component of 1.8Mt @ 2.7% HM.  Strandline deposition of heavy mineral formed the high-grade component.

Contained valuable heavy mineral  (VHM) at West Mine North totals 498kt composed of 383kt of ilmenite, 48kt of zircon, 53kt of rutile and 14kt of leucoxene, with the indicated component 465kt of contained VHM comprising 359kt of ilmenite, 44kt of zircon, 49kt of rutile and 13kt of leucoxene and an inferred component of 34kt of contained VHM comprising 24kt of ilmenite, 5kt of zircon, 4kt of rutile and 1kt of leucoxene.

The high-grade strandline core at West Mine North HM has a strike length of 4,000m and up to 270m width with an average thickness of 19m, from 1m to 49.5m depth.  The dunal proportion of the deposit has a strike length of 4,000m and is up to 2,300m with an average thickness of 8m, from 13.5m to 48m depth (see Mineral Resource and Ore Reserve Statement, ASX release 03 October 2018).

Metallurgical scoping test-work has been completed by Robbins Metallurgical.  This produced primary and secondary ilmenite products typical chloride grade ilmenite quality. Based on grade data and recovery data it can be concluded that material from West Mine North when processed will produce products of high quality.
