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 project lies wholly within cleared freehold land on three granted Mining Leases: M70/965, M70/1153 and M70/872.
On 7 November 2011, Sheffield announced a Mineral Resource for West Mine North of 42.58 million tonnes @ 2.8% HM (Measured and Indicated) containing 1.2 million tonnes of HM at a 0.9% HM cut off. Within this is a central high-grade strandline component of 10.09 million tonnes @ 7.7% HM containing 779,000t HM (Measured and Indicated).
The mineral assemblage comprises 7.9% zircon, 10.1% rutile, 59.2% ilmenite and 6.4% leucoxene. The ilmenite has a TiO2 content above 60% and is therefore potentially suitable for chloride route or synthetic rutile processing.
The deposit is 4km long, up to 270m wide and 10m to 35m thick, with variable thickness of overburden from 5m to 20m.
