The overall drilling campaign was designed to test four previously unexplored palaeochannels in addition to one extensive basement target defined by the 2018 airborne spectrometric and magnetic survey.
The exploration drilling on EPL3670 totalled 3,009m for 153 RC holes. Figure 1* shows the Nova JV tenements - EPLs 3669 and 3670. Figure 2* shows the exploration targets and drill hole locations on EPL3670. Results of palaeochannel drilling at Day Gecko, Bibron and
Palaeochannel Targets
The Namaqua palaeochannel, discovered in 2017 on EPL2669, showed substantial calcrete-associated uranium mineralisation and highlighted the prospectivity of other channels identified from reinterpretation of an earlier flown VTEM survey.
In addition, research by JOGMEC using remote sensing techniques, i.e. surface temperature difference (STD), identified additional palaeochannel targets on EPL3670 designated
Target
Nine holes for 180m were completed along a north-south drill line at
Bibron, Day Gecko and Targets
48 vertical RC holes for 807m were drilled at the Bibron, Day Gecko; and
Basement Targets
Komodo 2 Target
At Komodo 2 a basement target approx. 9km by 3km was interpreted to occur beneath Tertiary and Quaternary cover sediments. 96 shallow RC exploration holes for 1,980m were drilled along six west-northwest/east-southeast trending lines. Although numerous holes showed downhole radiometric anomalism, none returned values over 100ppm eU3O8 over 1m. Anomalous intersections were sampled and submitted for assay to verify results and to determine whether follow-up drilling is required. Figure 4 shows a cross-section through the northern part of the area.
Mineralised RC hole intersections above the 100ppm eU3O8 over 1m cut-off are tabulated in Table 1*, Appendix 1*. All RC drill hole locations are listed in Table 2*, Appendix 1*.
Conclusion
The 2019 exploration drilling on the Nova JV EPL3670 is now completed and a detailed evaluation of the drill results is underway.
To date, the review suggests that limited follow-up drilling of the palaeochannel targets Skink/
On EPL3669, Namaqua remains open to the north-east and is earmarked for follow-up drill testing as previously reported.
In addition, prospective leucogranite at Barking Gecko will require follow-up work.
The next stage of exploration on both EPLs 3669 and 3670 will involve some ground surveys in Q1 of 2020 to determine possible follow-up drill hole locations.
