REPTILE PROJECT, NAMIBIA (EPLs 3496, 3497) – 100% Deep Yellow

Activities on the Reptile Project focused on EPL 3497 and, on 3 October, Deep Yellow Ltd (Deep Yellow) reported on encouraging drilling results where new continuous mineralisation has been identified in the Tumas 1 East palaeochannel area. Drilling was also conducted in the S-Bend channel area to the north which did not identify significant mineralisation. This EPL is held by Reptile Uranium Namibia (Pty) Ltd (RUN), part of the group of companies wholly owned by Deep Yellow.

As previously announced, drilling programs commenced in July 2018 with semi-regional exploration drilling in the S-Bend Area. This regional program was completed at the end of August with 148 RC holes drilled for 2,171m and was immediately followed by exploration

drilling starting early September, east of the Tumas 1 uranium deposit with 95 RC holes for 1,199m drilled to end of September on the Tail 1 tributary channel.

Post quarter, a further update was released to the ASX on 17 October 2018 detailing drilling results to 12 October during which 49 exploration holes for 564m were completed testing Tails 1,2 3 and 4. In total, 144 holes have been drilled for 1,763m in the region east of the Tumas 1 deposit. This work focussed on:

• a) defining the extent of the newly discovered continuous mineralisation found within the Tail 1 tributary; and

• b) exploring the tributary paleochannels occurring immediately to the south (Tails 2 and 3) and to the north (Tails 4 and 5) of Tail 1 as can be seen in Figure 2.

Tumas East Drilling

Up until 12 October, work concentrated on testing for presence of mineralisation in four of the five tributaries converging into the main palaeochannel at the Tumas 1 deposit. A total of 121 holes were drilled for 1,561m in the Tail 1 tributary. Five of these holes extended north into the newly discovered Tail 4. 23 RC holes for 202m were drilled in Tails 2 and 3.

The exploration drilling at the main tributary (Tail 1, Fig. 2) is now completed and has outlined a uranium rich channel 4.6km in strike length showing continuous calcrete uranium mineralisation. Channel widths are ranging from 200m to 900m. The mineralisation is located at shallow depth between 0 to 17m below surface. Except for localised hot spots, large parts of this mineralisation do not show any surface radiometric expression.

A drill line across Tail 1 was extended to the north and identified uranium mineralisation greater than 100ppm eU3O8 over 1m in 4 of 5 holes in a new tributary, Tail 4 (Fig 2). This could add an additional 4km of untested prospective palaeochannel to this target area. Exploration drilling testing tributary channels Tails 2 and 3 involving 23 RC holes and 202m did not identify significant mineralisation in these channels.

Drill spacings varied from 50 to 100m along lines 200 to 800m apart. Of the 121 holes drilled at Tail 1, 86 returned positive results of more than 100ppm eU3O8 over 1m. This reflects a 71% success rate. Average grades at a 100 ppm eU3O8 cut-off are 315ppm and average thickness close to 6m. Significant intersections ranged from 300ppm to 1099ppm eU3O8 having thicknesses of 5m to 12m.

Drill hole locations are shown in Figure 2. Figure 3 shows a drill cross-section highlighting the continuity and thickness of the mineralisation. Figure 4 shows a drill cross-section extending from the main tributary Tail 1 into one of the northern untested channels (Tail 4). Tail 5 remains untested at this stage.

The immediate ongoing drilling is aimed at concluding the broad definition of the mineralised system occurring in the general Tumas 1 East area after which work will concentrate on infill drilling for upgrading the uranium resource base of the project.

Analysis/Conclusion

The results of the ongoing exploration in the Tumas 1 East region are very promising. The current drilling has now defined a 4.6km extent of the new continuous zone of mineralisation associated with the eastern extensions of Tumas 1 in Tail 1 tributary. As importantly, new uranium mineralisation north-adjacent to the Tail 1 tributary paleochannel has opened the potential for further mineralisation in the Tail 4 tributary. The Tail 5 tributary remains untested.

The current drilling is still ongoing focusing on extending the known mineralisation identified at Tumas 1 East in Tail 4.

The Tumas 1 East Tail 1 discovery is clearly demonstrating the potential for further additions to the uranium resource base. The mineralisation is expected to be found in tributary channels entering the main channel from the north-east makes this a priority region for upgrade of the overall palaeochannel-related resource base. As previously shown, the uranium mineralisation is not confined to one simple, single channel but rather is associated with a complex palaeodrainage system containing several channels.

There are now five distinct mineralised zones (Tumas 1 & 2, Tumas 3, Tubas Sand/calcrete deposits and Tumas 1 East) identified within the 125km of palaeochannels that occur within the Reptile Project tenements (Figure1). Some 60%, or approximately 75 km, of this palaeochannel system which regionally deepens toward the west remains to be properly tested.

Drilling during the late October to mid-December period will concentrate on increasing the uranium resource base in the Tumas 3 West and Tumas 1 East areas. Because of the new discovery made within the Tail 1 tributary channel there are now two definite targets needing resource definition work. For this reason, Deep Yellow is currently seeking to contract a second drill rig so both priority areas can be investigated concurrently and will be the focus for completing the balance of the 10,000m planned to be drilled by the end of 2018.

An updated Inferred Resource estimation for Tumas 1 East and the area west of Tumas 3 is expected to be delivered early 2019.

NOVA JV, NAMIBIA (EPLs 3669, 3670) – 65% Deep Yellow

JOGMEC is currently earning a 39.5% equity interest in the Nova JV to be achieved after $4.5M has been spent by them over a four-year period. Work on the Nova JV is focussing on target definition and drilling to test for both basement- related uranium targets (Rössing/Husab style deposits) and palaeochannel/calcrete associated uranium targets (Langer Heinrich style deposits).

Exploration on the Nova JV tenement concentrated on ground follow-up of targets defined by the high resolution airborne magnetic and radiometric survey.

On EPL 3669 the work identified calcrete-type targets for follow-up drilling at Namaqua, Bowsprit, Bungarra and Iguana and basement targets for Alaskite-type uranium mineralisation at Iguana where ground work identified a set of uranium bearing veins in sheared granitic lithologies worthy of follow-up drilling.

On EPL 3670 detailed ground radiometric surveys identified drill targets for Alaskite-type uranium mineralisation at Cape Flat, Agama and Meerkat Hill, where extensive, uranium dominated radiometric anomalies are associated with sub-cropping prospective leucogranite intrusive rocks.

A 5,000m RC drilling program commenced in early October and this work is expected to be completed by mid-December 2018 after testing the 7 targets that have been identified for drilling.
