GWR holds a 100% interest in the Hatches Creek Polymetallic Tungsten Project, an advanced stage tungsten project located in the Northern Territory of Australia covering the large high grade historical Hatches Creek mining centre.
Following a highly successful maiden drilling program in November 2016, a follow-up RC drilling campaign will commence in late July 2017.
The Hatches Creek project consists of two granted tenements occupying 34 km2 (EL22912 and EL23462), which cover the entire historic Hatches Creek tungsten mining centre. Hatches Creek is a large historical high grade tungsten mining centre where mining was undertaken between 1915 and 1957. Previous recorded production is approximately 2,840 tonnes of 65% WO3.
The Project is located 375 km north east of Alice Springs in the Northern Territory of Australia (Figure 1).

Exceptional drilling results
Exceptional results were achieved in the maiden RC drilling program undertaken at the Hatches Creek project located in the Northern Territory (see ASX announcement 15 March 2017). The 18 hole 1,739 metre RC drill program, focused on the Pioneer, Copper Show, Hit or Miss and Treasure prospects , while an additional 11 prospects remain to be drilled. The RC holes were targeted based on previous dump sampling results, mapping and accessibility.
The drilling has intersected significant tungsten and copper mineralisation in all four areas targeted and at Treasure and Hit or Miss over much larger widths than expected. At Pioneer, the tungsten and copper mineralisation is also accompanied by gold mineralisation confirming the polymetallic nature of the mineralised structures.
At Treasure, broad zones of tungsten and copper mineralisation were intersected. Where the initial target was narrow high grade zones, the drilling returned 53m at 0.26% WO3 and 0.13% Cu, from 63m in HCRC014 and 44m at 0.21% WO3 and 0.12% Cu, from 55m in HCRC013.
Intersections at Hit or Miss included wide zones such as 36m at 0.18% WO3 and 0.24% Cu in HCRC011 from 52m and narrow high grade intersections including 2m at 3.05% WO3 from 3m in HCRC010.

At Pioneer, the Company intersected multiple stacked zones of mineralisation that correspond with historical mining zones. Several of the holes intersected at least three stacked mineralised zones. Better results included 2m at 1.60% WO3, 0.96g/t Au and 0.36% Cu from 43m in HCRC004, also in HCRC004, 1m @ 1.96% WO3, 1.58g/t Au and 0.28% Cu, from 80m and 3m at 0.63% WO3 from 81m in HCRC002. Eight of the mineralised tungsten zones also had coincident gold grades of greater than 0.8g/t Au.
Following a highly successful drilling program completed in November, 2016, which confirmed multiple high-grade tungsten prospects, the Company is planning (see announcement here) the next campaign of RC drilling, to commence in July, 2017.
The program will have two parallel aims. Firstly, step out drilling will be undertaken along strike of mineralised zones at Treasure, Hit or Miss and Pioneer. The aim of this drilling is to enable sufficient drilling density to provide a maiden Mineral Resource estimate.
In the second focus for the program, reconnaissance drilling will be undertaken on five new prospect areas within the Hatches Creek project area. These prospects, known as Green Diamond, Black Diamond, Bonanza, Silver Granite and Kangaroo, are all sites of historical mining and prospecting activity.
