Kalahari Exploration Update
Drilling Update at Witvlei and Snowball
Perth, Western Australia - 8 March 2022 - The Board of Noronex Limited (Noronex or the Company) (ASX: NRX) is pleased to provide an update on the exploration of its suite of copper projects in Namibia.
Highlights
- Both drill rigs have moved to the Hennep Prospect at Snowball East testing a number of geological and geophysical targets at the prospective contact.
- A further program of drilling is being planned at Dalheim to follow up anomalous geology intersected in the initially 13 holes once results are received. An infill soil survey is planned to assist targeting further drilling.
- Results from the drilling completed at Okasewa have been received with an intercept south of the known resource that reports :
-
13m @ 0.85 % Cu from 2m in 21OKRC015 and o 5m @ 1.0 % Cu from 21m and
o 1m @ 1.2 % Cu from 144m
o 2m @ 0.76 % Cu from 133m in 21OKRC004
-
13m @ 0.85 % Cu from 2m in 21OKRC015 and o 5m @ 1.0 % Cu from 21m and
- Three holes have been completed at Kehoro North at Snowball West testing a chargeable IP anomaly.
Witvlei Drilling
The focus of the current exploration efforts is on five targets on the Witvlei project, comprising two Exclusive Prospecting Licences (EPLs 7028 and 7029) covering 390 km2 that are prospective for sedimentary Cu-Ag mineralisation.
The initial program has now been completed and further work is being evaluated and will be finalised when full results have been received for the drilling. The program has included 71 RC holes for a total 13,947m.

Okasewa
Results from the holes completed have been received from Okasewa from the 18 holes for 3,600m with an intercept in hole 21OKRC015 identified from a strong Copper soil anomaly.
Intercepts include :
-
13m @ 0.85 % Cu from 2m in 21OKRC015 and o 5m @ 1.0 % Cu from 21m
o 1m @ 1.2 % Cu from 144m
o 2m @ 0.76 % Cu from 133m in 21OKRC004
The holes intersected the Eskadron Formation containing brown siltstone and interbedded sandstones with debris flow. Malachite staining was intercepted down to approximately 20m vertically with fine pyrite, chalcopyrite and chalcocite developed in the siltstone horizons at depth below.
Samples have been collected in 3m composites and at 1m intervals where mineralisation was visually noted. Samples were prepared in the ALS sample preparation facility in Namibia and assayed at their laboratory in South Africa (see Table 1).

Dalheim
Drilling has been completed for the time being as the rigs move to Snowball. A further program is being planned to follow up anomalous geology intersected in the initial 13 holes drilled for 2,718m.
An infill soil survey is being planned prior to further work as samples are on a 400 by 80m grid which will be close up to 100m lines and 40m samples over anomalous areas with a combined pXRF and analytical survey.
Diamond drilling is expected to follow up on these regional RC hole fences to define the style and character of the geology and mineralisation.

Snowball Joint Venture Drilling
Three holes have been completed on the western Snowball tenement at Kehoro North (Havango) testing a major structure and IP chargeability anomaly.
A program of ten holes is now underway on the eastern tenement with two rigs drilling at Hennep to test the prospective NPF-D'Kar contact and the chargeability anomalies defined.
