Kalahari Metals Limited: Project Update
("Metal Tiger" or the "Company")
: Project Update
(AIM: MTR), the London Stock Exchange AIM listed investor in natural resource opportunities, is pleased to provide an update in respect of the copper focused explorer, (“KML”), in which Metal Tiger has a 62.2% equity interest.
KML is preparing to recommence drilling at the Kitlanya East (“KIT-E”) Project by the end of June, as is now starting to gradually relax COVID-19 national lockdown restrictions. The KIT-E drilling programme, which is testing geological contacts and structures prospective for hosting copper-silver mineralisation (announced on ), had to be temporarily suspended on in compliance with COVID-19 related emergency legislation.
During the lockdown period, KML has taken the opportunity to re-model and interpret available data over the KIT-E property alongside the preliminary drilling results. Key findings from this assessment have refined follow-on drilling targets and shown there are many similarities with the geological setting of the neighbouring Sandfire Resources T3 and A4 deposits.
, Chief Executive Officer of Metal Tiger, commented:
“We are pleased to report that KML is planning to recommence the diamond drilling programme at their on the Kalahari Copper Belt, by the end of the month, as the government gradually relaxes COVID-19 related lockdown restrictions.
Whilst site work had to go on hold, KML has taken the opportunity to incorporate the preliminary drilling datasets into the geophysical, remote sensing and geochemical models, updating and fine tuning the target interpretation that shows strong geological similarities with the neighbouring Sandfire Resources deposits.”
KIT-E Project Interpretation
During the lockdown period KML has incorporated the preliminary drilling data with the geophysical modelling, resulting in the following key observations:
which may help visualise the information in this announcement are available to view at the following link:Illustrative figures.http://www.metaltigerplc.com/kml-update-0620
The KML interpretation has highlighted the structural potential for the northern to host similar deposits to neighbouring targets on Sandfire Resources’ licence holding, as well as more conventional anticline limb and hinge mineralisation in a similar setting to Cupric Canyon Capital’s deposit.

KIT-E Project Regional Setting
Reprocessing of regional geophysical datasets illustrates interesting parallels between the Sandfire Resources A4 deposit setting and the northern margin of the KIT-E project:
See Figure 2:High resolution digital elevation model with fold structures of interest highlighted. Although the entire area is covered by sediments, features from the sub-cropping geology are clearly apparent. Heliborne magnetic data with fold structures of interest highlighted.

AEM and Magnetic Modelling
Remodelling of the detailed airborne electromagnetic data, collected over the northern portion of the by New Resolution Geophysics in early 2019, has added considerable value in terms of understanding the structural setting of targets in this area. A variety of different geophysical forward modelling and inversion routines were tested, including ‘traditional plate modelling’, ‘AIRBEO controlled layered earth modelling’, ‘VPem 1D layered earth’ and ‘full 3D modelling’. The results of the modelling appear to favour a local synclinal feature developed above a broader anticline.
Magnetic modelling of selected traverses across the KIT-E northern targets appears to further corroborate the AEM interpretation. Modelled susceptibilities agree favourably with values expected for mid and lower DKF stratigraphy. Modelling implies that the T3 Deposit stratigraphy may repeat in the KIT-E northern target area and could further suggest that A4, T3 and KIT-E north would see sub-crop of the same folded lower DKF stratigraphy with each target zone connected by synclines.
Figure 3 (A-D) illustrates the results of the AEM and magnetic modelling.

Note the trend towards a shallow – moderately dipping synclinal structure defined by weakly conductive plate and inversion results. 3D View of conductivity volumes with selected plate models, looking east, no vertical exaggeration.

Updated Target Generation
Developing targets in the northern part of the cover several mineralisation settings common in the Kalahari Copper Belt. These include: traditional mineralisation along the DKF-NPF contact on anticline limbs (e.g. , Zone 5N, Zeta and Plutus deposits); fold hinge related mineralisation (e.g. fold deposit); and structurally controlled mineralisation in the lower DKF above NPF anticlines (e.g. Sandfire Resources’ T3 and A4 deposits).
The remainder of the drill programme will test the structural and stratigraphic position of each target and occurrence of associated Cu-Ag mineralisation.
Figures 4 (A-D) illustrates the results of the updated target interpretation modelling.
See Figure 4: (A)Targets overlain on detailed vertical derivative magnetics. Simple schematic inserts illustrate the ideal setting for Cu-Ag mineralisation. Detailed structural interpretation has identified potential thrust bounded folds in lower DKF stratigraphy which may provide trap-sites for Cu-Ag mineralisation.

, which was incorporated in & on , holds interests in 12 highly prospective exploration licences covering a total area of 8,595km in the Kalahari Copper Belt of , comprising two 100% owned exploration licences, five exploration licences subject to a binding earn-in agreement with (includes the ), and five exploration licences held by 100% owned subsidiary, .
As announced on , Metal Tiger holds approximately 62.2% of KML together with a conditional 2% net smelter royalty over all KML’s wholly owned licences, being seven licences covering, in aggregate, 6,650km (together, the “Royalties”). The five exploration licences owned by (in which KML has a 51% interest) do not form part of the Royalties.

- On a regional basis, the northern anticline target in KIT-E shares many similarities with the Sandfire Resources A4 copper deposit.
- Modelling of the preliminary drill results with the airborne electromagnetic (‘AEM’) and magnetic data favour the development of thrust bounded local synclinal structures in more ductile lower D’Kar Formation (‘DKF’) carbonates, mudstones and siltstones, overlying a broader anticline with more competent Ngwako Pan Formation (‘NPF’) sandstone dominant sequences in the fold core.
- Follow-on drilling will target the margins of these structures with a view to intersecting mineralisation in a similar setting to neighbouring Sandfire Resources T3 and A4 copper deposits.
- Detailed remote sensing interpretation along with a review of historical soil sampling has identified further non-conventional targets which may represent thrusted anticlines of prospective lower DKF rocks providing potential trap-sites for copper mineralisation.
- Positive weathering features in the sub-cropping geology associated with fold structures along strike from both A4 and the KIT-E northern targets are clearly mapped in high resolution terrain data (Figure 2-A). This could be an indication of underlying NPF, which typically weathers positively based on outcrop/subcrop examples elsewhere in the Kalahari Copper Belt.
- Both A4 and the KIT-E northern targets are situated along a similar fold structure evident in the high-resolution magnetic data (Figure 2-B).
- Weak conductors have been delineated within the fold structures along strike from A4 and the KIT-E northern targets (Figure 2-C). These conductors are analogous to the marker conductors in the lower DKF units evidenced throughout the Kalahari Copper Belt with providing the most direct comparison.
