HIGHLIGHTS
– Resource drilling East and West of Tumas 3 has been completed for FY18.
o Uranium Mineralization identified in 46% of the holes in latest drilling.
o Mineralization is closed to the east and remains open to the west.
– Tumas 3 East extension drilling completed involving 3,892m in 153 holes carried out since 14 April announcement.
– Tumas 3 West extension started with 950m in 37 holes with mineralization remaining open requiring further drilling.
– Strongest intersections from the latest drilling include:
o TB3R645 – 7m at 366ppm eU3O8 from 5m.
– 1m at 1.096ppm eU3O8 from 14m.
o TB3R751 – 7m at 612ppm eU3O8 from 5m.
o TB3R808 – 13m at 708ppm eU3O8 from 15m.
– Mineralization is calcrete associated and hosted in palaeochannels, similar to the Langer Heinrich uranium mine located 30km to the north east.
Since the ASX release of 14 April 2018 resource upgrade continued east and west of the Tumas 3 uranium discovery with 190 RC drill-holes for 4,842m to end June 2018. Total drilling on the Palaeochannel Tumas for the 6 months ending 30 June 2018 amounted to 10.765m with 363 holes. Figure 1 (see link below) shows the palaeochannel system and prospect locations.
The resource drilling around Tumas 3 targeted further extending the mineralized area which was delineated from the November 2017 drilling. The latest drilling continues more continuous uranium mineralization over more than 3km. The Tumas 3 mineralization, including the newly identified tributaries, now occurs over 10.5km of continuous uranium mineralization when using a cut-off of greater than 100ppm Equivalent Uranium Oxide (eU3O8) over 1m. This drilling has been completed to date, where further drilling is planned later in 2018.
Of the total 190 holes drilled since 14 April 2011, 75 returned positive results – a success rate of 40 %. Tumas 3 The dropping success is compared to the original Tumas. eU3O8 ppm has been determined internally. The eU3O8 values are shown in Appendix 1 are based on a down-hole radiometric gamma logging with a fully calibrated Aus-Log gamma logging system. These results will be validated by a competent geophysicist for the forthcoming resource estimate. Figure 2 (see link below) shows the drill-hole locations in relation to the Tumas 3 resource. Figures 3 and 4 (see link below) show cross-sections through the mineralization east and west of Tumas 3 and highlight the continuous nature of mineralization across the channel.
Tumas 3 and the strong potential for continuation of uranium mineralization further to the west, which remains open.
Analysis
The resource drilling of the Tumas 3 resource identified new mineralization and was eventually closed off in this direction. The total Tumas 3 mineralization now extends over 10.5km including 3 associated tributary palaeochannels. The width of the mineralization varies between 200 and 400m in the main channel and 100 to 200m within the tributaries. Thickness of the mineralization is variable ranging 1 to 13m. Importantly, the mineralization remains open to the wind, which is scheduled for the second half of 2018.
The mineralization that has been extended to Tumas since the November 2017 drilling has no surface radiometric expression. This confirms that, from the advantage gained by good reinterpretation of airborne data.
The latest drilling extended the Tumas 3 mineralization by 3km along the main Tumas channel. Significantly, the results are clearly showing that the mineralization is more likely to be associated with the mineralization of Tumas. regarded. As previously shown, the uranium mineralization is not confined to a single, single channel but rather is associated with a complex palaeodrainage system with several channels that head westward to the Pacific Ocean.
Drill-hole cross sections across the Tumas 3 East and West extensions (see Figures 3 and 4) show the continuous nature of uranium mineralization and also the variability and complexity of the palaeochannel topography.

Conclusion
This, the third hole in the history of the world, has been changed in the direction of success, and it has been confirmed that Tumas 3 resource can be expanded. Uranium-fertile, an important expansive exploration of the uranium-rich potential of this project.
There are now 4 distinct mineralized zones (Tumas 1 & 2, Tumas 3 and Tubas Sand / calcrete deposits) identified within the 125km of palaeochannels (see Figure 1 in link below) which occur within the Reptile project tenements. Some 70%, or approximately 85km, of these palaeochannels remain to be adequately tested.
An updated resource estimate to include the recent drilling results is expected and expected to be released by mid July 2018.
A new drilling program with continued focus on the prospective palaeochannels is planned to start in the middle of July EPL 3497. Initially this will test targets in the east of the S-Bend and Tumas 1 areas. This article is only available in the following languages:
