Deep Yellow Limited announced completion of the RC resource upgrade infill drilling program at the Tumas 3 Central deposit, located on EPL3496. The Project is held by Deep Yellow through its wholly owned subsidiary Reptile Uranium Namibia (Pty) Ltd. (RUN). The mineralization at Tumas 3 (comprising Tumas 3 Central, Tumas 3 West and Tumas 3 East) occurs as a discrete mineral deposit, occurring separately from the other deposits so far discovered within highly uranium fertile Tumas palaeochannel system, namely, Tumas 1 (which also includes Tumas 1 East) and Tumas 2 in addition to Tubas Red Sand/Calcrete deposits. Infill drilling moved to Tumas 3 Central on 28 April 2021 following completion of drilling at Tumas 3 East, with 359 holes drilled for 7,634m by 27 May. Work is now progressing at Tumas 3 West. Since the beginning of the program in February 2021, 804 holes for 14,621m have been drilled. Three drill rigs are engaged for the work. The infill drilling program is focused on achieving a drill hole spacing sufficient to enable a resource conversion from Inferred to Indicated JORC resource status. Importantly, drilling completed at Tumas 3 Central is indicating that expectations for the conversion rate to Indicated Resource category are being met, with 48% of the 359 holes completed returning uranium mineralization greater than 100ppm eU3O8 over 1m, and 25% showing uranium mineralization greater than 200ppm eU3O8 over 1m. The equivalent uranium values are based on down-hole radiometric gamma logging carried out by a fully calibrated Aus-Log gamma logging system. HIGHLIGHTS: 359 holes for 7,634m completed at Tumas 3 Central: Drilling aimed at converting remaining Inferred Resources to Indicated JORC status and defining the periphery of the Tumas 3 deposit to expand the DFS LOM to 20+ years; 804 holes for 14,621m drilled since February 2021. 48% of holes drilled intersected mineralization greater than 100ppm eU3O8 over 1m. Best intersections (200ppm eU3O8 cut-off grade) include: T3I930: 10m at 1,945ppm eU3O8 from 28m; T3I963: 8m at 2,242ppm eU3O8 from 10m; T3I973: 9m at 1,897ppm eU3O8 from 7m; T3I771: 5m at 1,222ppm eU3O8 from 16m; T3I1151: 8m at 754ppm eU3O8 from 16m.
