Kalahari Exploration Update
Fiesta Prospect Review, Humpback Project
Perth, Western Australia - 13th January 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
-
In the Humpback EPL application, results compiled from historical drilling at the Fiesta prospect have highlighted significant Copper and Silver intercepts at the prospective NPF-
D'Kar contact including:
- 8m @ 2.5% Cu, 78 g/t Ag from 127m (True Thickness ~4m) in FIER010 o 13m @ 1.4 % Cu, 1 g/t Ag from 118m (True Thickness ~6.5m, Oxide) and
o 31m @ 0.9 % Cu, 33 g/t Ag from 154m (True Thickness ~15.5m) in FIER027 o 9m @ 1.8 % Cu, 82 g/t Ag from 224m (True Thickness ~4.5m) in FIER031
Drilling has defined a steeply dipping mineralised sheet over three and a half kilometres strike length with pods of thicker higher grade Copper.
- Regional drilling surrounding the Fiesta Prospect has reported anomalous Copper and Silver on the prospective horizon over a fifteen kilometres strike length.
- The Copper intersected demonstrates the potential along strike especially at key structural targets in the Snowball JV and Humpback applications that will be the focus for the 2022 drilling.
Commenting on the announcement, Noronex Chief Geologist, Bruce Hooper said:
"Early analysis of the Humpback applications highlight significant Copper developed along the prospective contact, giving great confidence in discovery of further prospect in Noronex tenements. Detailed interpretation of this drilling and historical ground geophysics is ongoing to target follow up when the tenements are granted."

Background
The focus of the current Namibian drilling is on five targets in the Witvlei project that are prospective for sedimentary Cu-Ag mineralisation. Two rigs are drilling at the Okasewa Prospect with 10,500 metre of a planned 12,000 metre project completed so far.
Ground geophysics including IP, NSAMT and ground magnetics is underway on the recently acquired Snowball Project. The setting is favourable to host a large copper deposit on a paleogeographic high under shallow sand cover and has not been previously drilled. An initial drill program is planned for later this month.
Six new applications have been lodged and accepted by the Ministry of Mines over large prospective parts of the Kalahari Copper Belt under shallow cover. The Humpback applications cover the prospective NPF-D'Kar contact to the east of Snowball.
Noronex's exploration package in Namibia now covers over 6,000 km2 of the highly prospective but relatively underexplored Kalahari Copper Belt. The tenements hold ~300 kilometres of the targeted contact between Witvlei and the Botswana border.

Humpback EPL Application Review
Interpretation of historical data, acquired over the new Humpback Project applications have defined a substantial exploration program with 123 holes completed at and along strike from the Fiesta Prospects by EISEB Exploration Pty Ltd. The majority of the drilling occurred between 2009 and 2015 including in a Joint Venture with Cupric Canyon, a private equity

backed mining company. A further 15 historical holes were drilled in other portions of the new application areas.
A significant proportion of the drilling intersected Copper mineralisation over a 3.5 km strike length at the Fiesta Prospect.
Figure 2. Drilling and intercepts from historical drilling at the Fiesta Prospect.
The mineralisation is hosted in a narrow, steeply dipping sheet of mineralisation corresponding to the prospective NPF-D'Kar contact horizon on the northern limb of an overturned antiformal structure.
Intercepts include:
-
8m @ 2.5% Cu, 78 g/t Ag from 127m (True Thickness ~4m) in FIER010 o 13m @ 1.4 % Cu, 1 g/t Ag from 118m (True Thickness ~6.5m, Oxide) and
o 31m @ 0.9 % Cu, 33 g/t Ag from 154m (True Thickness ~15.5m) in FIER027 o 9m @ 1.8 % Cu, 82 g/t Ag from 224m (True Thickness ~4.5m) in FIER031
True thickness has been estimated by building a wireframe of Zone 1 over 3.5 km strike, intercepts are between 40 and 60% of the downhole intercept so an average of 50% has been extrapolated across the drilling.
Mineralisation is hosted in a siltstone horizon and is predominantly chalcocite and chalcopyrite with minimal sulphides. Mineralised intercepts defined were:
