Metal Tiger (AIM:MTR), the London Stock Exchange AIM listed investor in strategic natural resource opportunities, today provided an update on the ongoing drilling campaign at the Ngami Copper Project and Okavango Copper Project, in which the Company holds an interest in via its 59.81 per cent. investment in Kalahari Metals Limited (“KML”).
These inaugural diamond core drilling works at the NCP and OCP are testing geological contacts within fold-hinges identified by airborne electromagnetic (“AEM”) geophysics, which are thought to be prospective for hosting upgraded Copper-Silver (Cu-Ag) mineralisation.
Michael McNeilly, Chief Executive Officer of Metal Tiger plc, commented:
“This is a very positive start to KML’s inaugural drilling campaign, and we are delighted that the airborne geophysics modelling and the technical team’s iterative interpretation of this in conjunction with magnetics and other factors is proving a reliable methodology for targeting the D’Kar – Ngwako Pan geological contact which is often associated with copper and silver mineralisation on Botswana’s Kalahari Copper Belt. We are very encouraged by the visible copper mineralisation seen in the core and look forward to testing for further mineralisation along strike. This bodes well for future drilling campaigns, especially at the Kit-East project which is proximal to the T3 Project. I am encouraged by the thoroughness and professionalism that goes into the geological interpretation that has allowed for such early success.”
· Drill intersections into the priority Fold Nose Target at OCP have identified veinlet and disseminated sulphide dominant Cu mineralisation over a broad 25m zone on the northern side of the fold-hinge. Drilling has started along strike from this hole.
· To date, nine drill holes totalling 2,008m have been completed across both projects:
o NCP: Seven holes (NCP01 to NCP07), totalling 1,381m drilled;
o OCP: Two holes (OCP01 and OCP02), totalling 627m drilled.
· Drilling at both the NCP and OCP has successfully intersected the D’Kar formation (“DKF”) – Ngwako Pan formation (“NPF”) contact in fold-hinge settings with associated Cu mineralisation.
· AEM modelling of Kalahari cover thickness and the position of the DKF-NPF contact has been verified by the drilling to date, thus confirming the AEM data as a tool for targeting Cu-Ag mineralisation.
Ngami Copper Project Drilling Summary
Drilling has focussed on testing fold-hinge targets identified in AEM modelling and high-resolution magnetic interpretation with a total of seven drill holes completed, totalling 1,381.05m. The Kalahari thickness over NCP varies significantly ranging from 58m to 133m. Unlike the OCP, the drill tested AEM conductor correlates very well with a 35 – 62m thick mudstone package of likely late Karoo age, which overlies prospective older DKF stratigraphy. Drilling was therefore reprioritised using the magnetic interpretation with NCP06 intersecting the DKF-NPF contact at 254.9m with associated trace amounts of Cu carbonates. Drilling has demonstrated the potential for fold-hinge related mineralisation in this project area.
Okavango Copper Project Drilling Summary
To date, a total of 627.10m have been drilled from two drill holes over the OCP Fold Nose Target. In both cases, drill holes (OCP01 and OCP02) have intersected the prospective DKF-NPF contact and confirmed that the folded conductor identified in the AEM modelling correlates well with a 35-50m thick package of carbonaceous siltstone (termed the CAR Marker) in the lower DKF. This recent understanding of the AEM conductor is now being used to accurately position additional drill hole positions without a requirement for expensive stratigraphic pilot holes.
The first hole (OCP01) was drilled into the hinge zone of the northeast plunging anticline intersecting trace amounts of Cu carbonates hosted in fractures from 183-202m (within DKF Massive Marker Sandstone (“MSST”), as well as from 280-311m (within NPF sandstone)).
The second hole (OCP02) was positioned 1.6km due west of OCP01 in order to test the northern limb of the anticline, proximal to the fold nose. OCP02 proved more successful, intersecting a broad mineralised zone which included visible Cu sulphide mineralisation from 240.5-264.1m. This mineralised package is located in the lowermost portion of the DKF, below the MSST and proximal to the DKF-NPF contact. The Cu sulphide mineralisation is associated with thin, cross-cutting carbonate and quartz veinlets, as well as disseminations within the units. Additional limited Cu sulphide mineralisation is observed below the DKF-NPF contact within the NPF from 255.8-264.1m.
The core is currently in the process of being cut and sampled, prior to being sent to an analytical laboratory for geochemical analysis. Additional drilling is planned to test for continuation of mineralisation along strike from OCP02.
KML, which was incorporated in England & Wales on 3 May 2017, holds interests in 12 highly prospective exploration licences covering a total area of 8,595km2 in the Kalahari Copper Belt of Botswana, comprising two 100% owned exploration licences (consisting of the Ngami Copper Project and the Okavango Copper Project), five exploration licences subject to a binding earn-in agreement with Triprop Holdings (Pty) Limited, and five exploration licences held by Kitlanya Limited (“Kitlanya”) subject to an agreement with Resource Exploration and Development Ltd (“RED”).
As announced on 10 April 2019, KML has entered into a binding agreement with RED to purchase 100% of Kitlanya, which is conditional upon approval of the change of control of Kitlanya being granted by the authorities in Botswana and receipt of an updated letter of good standing for the licences. On completion of the acquisition, the previous earn-in agreement between RED and KML will terminate.
On 31 May 2019, Metal Tiger announced a further US$1.1m equity investment into KML, increasing its interest to 59.81%. The Company’s interest will reduce to 53.17% upon completion of KML’s purchase of Kitlanya. Notwithstanding Metal Tiger’s majority shareholding in KML following this investment, KML does not fall to be treated as a subsidiary of Metal Tiger as an agreement between the shareholders of KML precludes Metal Tiger from exercising control.
