Reverse Circulation percussion (RC) and Diamond Core (DC) drilling to be undertaken within the Target Areas (Figure 1) has been re-scheduled to commence in early January 2017 – weather permitting. The re-scheduled commencement date is later than the anticipated September 2016 start-up date (ASX 26 May 2016) due to delays in statutory approvals. However, given historical Torrington weather statistics, rain and wet conditions should be a lesser problem from January onwards and the drill programme may then be completed without a break (as would be required over the Christmas period) which should reduce overall logistical costs.
Figure 2 shows three phases of planned drilling (totalling 596 holes) submitted to the DRE. It is only Phase 1 (black lines) and the 5 sterilisation holes in the proposed plant site that will definitely be drilled, while Phases 2 and 3 will depend on the preceding Phase’s results. Additional infill drilling may be required for JORC Code estimation purposes within the grids.
The drill programme is designed to target 10,000 to 12,000 tonnes WO3 dependent upon the extent of tungsten bearing silexite bodies intersected. Potential additional resources for future drill programmes are outlined as an ‘exploration target range’ in the JORC 2012 report and as depicted in Figure 3.
