The Night Train prospect is located 20km south of Thunderbird. Mineralisation has been defined on one main line of drilling and is open in most directions.
At 1% HM cut-off the mineralisation is 1.6km wide and from 4.5m to 24m thick (average 11m), with an average HM grade of 4.04%. At 3% HM cut-off, mineralisation is 1.0km wide, from 3m to 12m thick (average 7.5m), with an average grade of 6.40% HM.
Night Train has a high value mineral assemblage with 92% VHM, comprising 15% zircon, 53% leucoxene, 8% HiTi leucoxene and 16% ilmenite. The heavy mineral is free from coatings and has a very high zircon content. The mineralisation is hosted by fine, clean, predominantly quartz sand.
Night Train is located just 2km from the proposed Thunderbird Project haul road or 20 km south east of the proposed Thunderbird process plant. This substantial new discovery is further evidence of Sheffield’s prime position in the emerging Canning Basin mineral sands province.
