Deep Yellow Limited (Deep Yellow or Company) is pleased to announce that the 14 hole, 3,561m Phase 1 follow-up drilling program at the Barking Gecko North prospect (EPL3669), commencing on 12 July 2021, was completed 6 October.

The Barking Gecko prospect is part of the Nova Joint Venture (NJV) located within EPL 3369 in Namibia.

The drilling program focused on defining the 3D setting of the mineralised alaskite intrusions to test for extensions of the strong mineralisation previously discovered at Barking Gecko North. The results of the initial four holes (for 1,012m) of the 14-hole, 3561m Phase 1 program were reported on 5 August. Subsequently, a further 10 RC holes were drilled completing this program.

Overall, the Phase 1 drilling returned encouraging results, with 13 of the 14 holes intersecting uranium mineralisation. The standout results have come from hole TN258RC, some results for which were included in the 5 August announcement. Hole TN258RC, having previously finished in mineralisation, was extended by 18m and now contains 70m at 503ppm eU3O8 within four intersections over an 83m zone from 178m depth. Other holes showing very encouraging results includeTN260RC with 14m at 381ppm from 130m and TN261RC showing 29m at 529ppm from 151m in two intersections. The NW-SE orientated drill line was drilled with holes spaced 100m apart, continuing extending previous anomalous drilling to the southeast with some infilling to 50m with holes TN256RC and TN258RC at its the south-eastern end.

Drilling further to the southeast indicates that mineralisation does not extend beyond hole TN264RC, limiting the strike length of the mineralised intrusions at Barking Gecko North to 700m. Although the drilling results appear to restrict the extent of the mineralisation to an area of 700m by 200m, the exceptional thickness and grade of some of the intersections and the fact that all holes within that zone are mineralised, require further work to evaluate the possible economic significance of Barking Gecko North.

Downhole optical televiewer logging (OPTV) is currently underway and structural interpretation of the imagery will be used to better define the main structural trend of the mineralised intrusions, currently interpreted to be northeast-southwest. In-house portable XRF (pXRF) assaying of all mineralisation at 1m intervals is underway, with results for TN265RC to TN269RC pending. The results available to date confirm that mineralisation is uranium dominant, with minor thorium associated.

CONCLUSION

The results from the Phase 1 drilling at Barking Gecko North remain encouraging, with the prospective nature of this zone being confirmed. The size of the prospective zone containing high grade and thick uranium mineralisation, as identified to date, appears to be restricted to 700m by 200m. However, further drilling is required to test the continuation of the mineralisation to the north and south as well as at depth. The Phase 2 drilling to undertake further follow-up for an additional 3,500m (and which will complete the approved annual budget) is planned for commencement at the latest early CY2022, once all results from the current drilling are fully evaluated.
