Metal Tiger plc (LON: MTR), the London Stock Exchange AIM listed investor in strategic natural resource opportunities, has today provided an update regarding the exploration activities of the Company’s Joint Venture, Tshukudu Exploration (Pty) Ltd, in the Kalahari Copper Belt in Botswana.
Highlights
- First phase of drilling at the 5km long A4 Dome has completed with 18 of 20 holes intersecting copper mineralisation. The A4 Dome lies only 8km from the planned processing plant for MOD Resources Limited’s (“MOD”) T3 Project.
- Drill hole intersections include significant widths and grades of both vein and Ngwako Pan Formation (“NPF”) contact type mineralisation.
- Potential for A4 Dome mineralisation is open with approximately one third (1.6km) of the prospective 5km strike drilled to date.
- High-level conceptual underground mining study, conducted by independent consultants Entech Pty Ltd, gives positive outcomes for a combination of room-and-pillar and long hole open stoping mining of NPF contact related mineralisation via a decline from surface.
- Decision to progress the A4 Dome programme towards a potential mineral resource estimate is expected to be made early 2019.
- Assay results include:

Michael McNeilly, Chief Executive Officer of Metal Tiger plc, commented:
“We are delighted to report the results of the first phase of drilling and a preliminary conceptual underground mining study on the A4 Dome, both of which indicate the potential for another significant copper resource only 8km from the planned T3 Project processing plant.
The findings provide strong support for a decision to step out the drilling to the rest of the A4 Dome prospective target area and start to work towards a A4 Dome maiden resource in early 2019. We look forward to updating shareholders on our progress in the new year.”
A4 Dome Drilling Background
- A4 Dome is an approximately 5km structural formation located 8km from the 60Mt (@ 0.98% Cu and 14g/t Ag) T3 Pit Project and planned processing plant.
- A4 Dome and the A1 Dome, together with the T3 Deposit, form part of the approximately 700km2 T3 Dome Complex.
- A4 Dome drilling displays two distinct mineralisation types, vein-hosted mineralisation associated with structures in the upper part of the dome and NPF contact hosted mineralisation which indicates there may potentially be a continuous blanket below the dome. The NPF contact is the basal contact of the copper host sequence (D’Kar Formation), overlying the distinctive oxidised red sandstone sequence (Ngwako Pan Formation).
- NPF contact mineralisation at the A4 Dome commonly occurs as a shallow dipping, 3-6m wide zone of locally high-grade chalcocite mineralisation, generally between 1.5% to 2.4% Cu, overlain by wide zones (15-50m down hole widths) of disseminated copper sulphides which average between approximately 0.9% and 1.1% Cu.
- NPF mineralisation has similarities to deposits in other sediment hosted copper belts (e.g. Zambian/DRC Copper Belt) where the increasing concentration of high grade, high tenor chalcocite towards the basal contact is referred to as ‘bottom-loading’.
- NPF contact is an important regional target in the Kalahari Copper Belt as it hosts substantial deposits including the 100Mt @ 2% Cu ‘Zone 5’ resource held by Cupric Canyon Capital, over 100km east of A4 Dome.
A4 Dome Conceptual Mining Study
- Independent underground mining consultants, Entech Pty Ltd, have undertaken a preliminary, conceptual underground mining study of the A4 Dome using inputs from one of Australia’s leading underground mining service providers, Barminco, a subsidiary of AusDrill.
- Study focused on concept of developing a decline to access the NPF contact, with relatively low-cost room-and-pillar ore extraction of higher-grade contact mineralisation and long hole open stoping of the overlying, disseminated mineralisation.
- While the underground mining study is only conceptual and has focused on the NPF contact at this stage, the preliminary findings are considered by the Metal Tiger Board to be very encouraging.
- Decision to expand drilling coverage along the A4 Dome and work towards a potential maiden mineral resource estimate, to include both NPF contact and the shallower vein hosted mineralisation, is expected to be made by the JV early 2019.
