• Additional high-grade uranium assays (U3O
received from the 2023 drill campaign at
Nabarlek, confirm previously reported 1 uranium mineralisation on the East Zone of the U40
Fault:
o 5.0m @ 0.54% (11.90 lbs/t) U3O 8 from 257m (RC220), including:
3.0m @ 0.82% (18.08 lbs/t) U3O 8
o 7.0m @ 0.37% (8.16 lbs/t) U3O 8 from 81m (RC221), including:
3.0m @ 0.58% (12.79 lbs/t) U3O 8
o 5.0m @ 0.30% (6.61 lbs/t) U3O 8 from 60m (RC229), including:
1.0m @ 0.59% (13.01 lbs/t) U3O 8
• Preliminary interpretation of the U40 East Zone shows that the near-surface uranium
mineralisation plunges shallowly to the south. Importantly the high-grade intercept in hole
RC220 (reported above) comes from the deepest hole in the U40 campaign, demonstrating
that uranium mineralisation continues well below the unconformity and well beyond the
current level of drill testing. This is a priority focus for follow-up in 2024.
• At Nabarlek North, uranium assays were received from previously reported 1 drilling north
of the historic Nabarlek Uranium Mine, including:
o 11.0m @ 0.15% (3.31lbs/t) U3O 8 from 36m (RC173), including:
1.0m @ 0.68% (14.99 lbs/t) U3O 8
o 13.0m @ 0.28% (6.17 lbs/t) U3O 8 from 41m (RC174), including:
1.0m @ 0.73% (16.09 lbs/t) U3O 8
o 5.0m @ 0.14% (3.09 lbs/t) U3O 8 from 33m (RC179)
• These Nabarlek North uranium intercepts all occur at the unconformity between the
overlying sandstone and underlying basement rocks and are indicative of a Nabarlek-type
structure nearby.
• The results trend into the Nabarlek Mining Lease (including hole RC179), with follow-up
drilling planned within the Mining Lease for 2024.
• Since last year’s drilling campaign commenced in June, the uranium spot price has
increased by almost 100% to its close of US$107/lb U3O 8 on Friday. This puts DevEx in an
enviable position as the Company continues to identify significant near-surface uranium
mineralisation within a well-endowed brownfields project at Nabarlek.
• The discovery of large, fault-hosted unconformity-type uranium deposits similar to the
nearby world-class Jabiluka Deposit or the prestigious Ranger Uranium Mine – which
produced 300Mlbs @ 0.23% (5.07 lbs/t) U3O 8 over 40 years – remains the priority focus
for DevEx.
