DEEP YELLOW : TUMAS DFS RESOURCE UPGRADE DRILLING PROGRAM COMPLETED

08/19/2021 | 09:58am EDT

Deep Yellow Limited (ASX: DYL) (Deep Yellow) is pleased to announce successful completion of the Tumas DFS resource upgrade drilling program (ASX announcement 11 February 2021) at the Tumas 3 and 1 East deposits, located on EPLs 3496 and 3497.

The Tumas Project is held by Deep Yellow through its wholly owned subsidiary Reptile Uranium Namibia (Pty) Ltd (RUN). Uranium mineralisation at Tumas 1, 2 and 3 is of the calcrete-type, located within an extensive, mainly east-west trending, palaeochannel system. Uranium mineralisation occurs in association with calcium carbonate precipitations (calcrete) in sediment-filled palaeovalleys.

The mineralisation at Tumas 1 East occurs as a discrete mineral deposit, occurring separately and east from the other uranium deposits within this highly fertile palaeochannel system, which includes Tumas 1, 2 and 3 in addition to the Tubas Red Sand/Calcrete deposits.

Infill drilling commenced at Tumas 1 East after completion of drilling at Tumas 3 West on 18 June 2021 (announced 13 July) and was completed on 12 August with 556 holes drilled for 6,982m. Completion of drilling at Tumas 1 East finalises the broader DFS resource upgrade drilling program, which focused on expanding the LOM to 20+ years and achieving a drill hole spacing sufficient to enable a resource conversion from Inferred to Indicated JORC resource status. Importantly, drilling completed at Tumas 1 East indicates that expectations for the conversion rate to Indicated Resource category are being met, with 70% or 390 holes of the 556 holes completed returning uranium mineralisation greater than 100ppm eU3O8 over 1m.

Infill drilling at Tumas 1 East concentrated on Tributary 1, where mineralisation shows the width, continuity and thickness expected to allow for high percentage conversions from resources to reserves. The mineralisation is located between 1 to 15m depth, with an average thickness of 5.5m at 100ppm eU3O8 cut-off. The equivalent uranium values (eU3O8) are based on downhole radiometric gamma logging carried out by a fully calibrated AusLog gamma logging system. Since commencement of the DFS resource upgrade drilling program in February 2021, a total of 1,473 holes were drilled for 24,942m, including 6 holes for metallurgical sampling and 20 holes for optical down hole surveys. Three RC drill rigs were engaged for this work. The primary objective of the DFS drilling program was to expand the current LOM from 11.5 years (as defined in the recently completed PFS) to 20+years (as targeted in the ongoing DFS).

With the drilling program now completed, a new Mineral Resource Estimate will be established for the Tumas Project and will become the basis for producing the updated Reserve status of the Project for incorporation into the Tumas DFS to enable consideration of a 20+year LOM. An intermediate updated Mineral Resource Estimate for Tumas 3 was announced on 29 July, delivering an impressive 117% direct conversion of the existing Inferred Mineral Resource to Indicated Mineral Resource category. The equivalent uranium values (eU3O8) are based on downhole radiometric gamma logging carried out by a fully calibrated AusLog gamma logging system.

The Probable Reserves (as identified for the recently completed PFS) and remaining Indicated and Inferred Resources established from the February to August resource upgrade drilling have all been derived from testing of only 60% of the known fertile regional palaeochannel system. Significant upside potential remains to further increase the resource base of the Tumas Project, with 50km of channel system remaining to be tested.

Commenting on the completion of the DFS resource upgrade drilling program, Deep Yellow Managing Director Mr John Borshoff said: 'Drilling at Tumas 1 East and the broader DFS program has delivered very impressive results, providing the team with a high-level of confidence in achieving our primary goal of increasing the Life of Mine at Tumas to over 20 years.

'We commenced this sizable and critical DFS workstream in February. Completing the resource upgrade drilling program in six months with such success is a testament to the team, its commitment and what we are building in Namibia. It is clear Tumas is becoming a tier-one asset with the key elements to support a successful uranium operation now evident and we look forward to continuing to advance and complete the DFS for this exciting project.'
