THE DRILL SERGEANT: Sheffield Resources (ASX: SFX) announced results from exploration drilling undertaken at the Night Train prospect at the company’s Dampier mineral sands project near Derby in northern Western Australia.
Night Train is located 20km southeast of Sheffield Resources’ world-class Thunderbird deposit, which forms part of the Dampier project.
Sheffield completed 23 aircore drill holes completed in September as part of an extensive regional exploration drilling program targeting additional large, zircon rich deposits suitable for downstream processing at the Thunderbird Dry Mineral Separation Plant.
27 metres at 5.29 per cent HM from 49.5m, including 22.5m at 6.17 per cent HM from 52.5m;
7.5m at 6.46 per cent HM from 27m, including 4.5m at 9.7 per cent HM from 28.5m;
12m at 4.54 per cent HM from 18m, including 7.5m at 6.15 per cent HM from 19.5m; and
6m at 8.92 per cent HM from 12m.
Sheffield said the latest results had extended the broad, high-grade mineralised intervals at Night Train it had previously identified by a single drill traverse.
At one per cent heavy mineral (HM) cut-off the mineralisation has a strike length of over 4.5 kilometres and a width of up to 1.5km.
Within this is a coherent high-grade zone (at 3% HM cutoff) of up to 22.5m thick (average 7.5m).
Sheffield has, to date, outlined the high-grade zone over an area of 4.5 square kilometres that is open along strike and down dip.
The mineralisation thickens to the south-southwest where it again remains open.
Sheffield indicated it would undertake further mineral assemblage testwork ahead of a maiden Mineral Resource estimate, scheduled for completion in Q1 2019.
“The discovery of additional high grade mineralisation containing high-quality zircon in close proximity to Thunderbird is particularly significant because it has potential to contribute to further growth and product flexibility,” Sheffield Resources managing director Bruce McFadzean said in the company’s announcement to the Australian Securities Exchange.
“This discovery is further proof that the Canning Basin is emerging as Australia’s next major mineral sands province.
“Our recent regional drilling program was extensive and there are many more results to follow.”
