Exploration Projects

A comprehensive exploration program across all MOD's project areas is currently underway in Botswana. The Company holds a dominant position in the Kalahari Copper Belt with prospective copper and silver licences at various stages of exploration.

Julian Hanna, Managing Director of MOD Resources, explains the major drilling campaign currently underway at the T3 Expansion Project (previously know as T3 Dome Complex).

T3 Expansion Project (MOD 70%)

The T3 Expansion Project forms part of a strategy to explore for potential resources which could be process at the planned T3 process plant and potentially add significant value to the project.

Drilling at the T3 Expansion Project commenced in the first half of 2018, testing previously undrilled Airborne EM anomalies along a >50km long section. These include large formational conductors and numerous discrete conductors.

Ten high priority targets were identified for the initial drilling phase which commenced with the A4 Dome.

A4 Dome

A4 Dome, only 8kms from the planned T3 process plant, was the first of seven 'buried domes' to be drilled at the T3 Expansion Project. Outstanding intersections included hole MO-A4-003D of 52m @ 1.5% Cu and 14 g/t Ag from 232.2m downhole depth, including 15.5m @2.9% Cu and 42g/t Ag. This was followed up with a second, deeper copper zone in the same hole which intersected 31.2m @ 1.1% Cu and 11 g/t Ag from 560m downhole depth. 

Localised mineralisation intersected in the upper part of the dome is high-grade vein style whilst the deeper mineralisation is associated with Ngwako Pan Formation (NPF) contact and may form a flat lying 'blanket' 450-500m below surface.

Drilling has scaled back at A4 Dome awaiting assays and interpretation of the results and is planned to increase in Q1 2019.

A1 Dome

The second dome outside the T3 Copper Project to be drilled is the ~12km long A1 Dome, located 22km east of of the 60Mt T3 Copper Project. Following a reinterpretation of the electromagnetic (EM) data, A1 Dome now comprises the A1, A2, A3, A21 and A27 prospects. Immediate success was reported in November 2018 with exceptional downhole widths of disseminated copper intersected in the first two holes.

Drilling at the A1 Dome is now on hold while results are being interpreted and a high level conceptual underground mining study is being undertaken on the potential of the NPF contact.

T20 Exploration Project (MOD 70%)

In addition to the T3 Expansion Project, the T20 Exploration Project (~100km west along strike from the T3 Expansion Project) is a high priority target area. Widespread copper and zinc soil anomalies occur within an area extending ~60km east to west and up to 20km north to south along the eastern part of the T20 Exploration Project. These soil anomalies appear to merge with the T4 anticline to the north.

Due to the successful use of AEM to identify drilling targets along the T3 Expansion Project, Tshukudu has completed a substantial AEM survey at the T20 Exploration Project. The survey consisted of three blocks with a total area of ~787km2 covering areas of strong soil anomalism.

Drilling to test these AEM and soil anomalies is currently underway at the T23 Dome and soon to commence at T4.

T7 Dome (MOD 100%)

MOD holds a 100% interest in four licences with a combined area of ~2,500km2 at the T7 exploration area, ~50km south of Ghanzi.

T7 licences cover a number of domes and potentially prospective geological contacts interpreted from magnetics.

Widely spaced soil sampling identified anomalous copper soil results and preliminary RC drilling intersected favourable sediments, similar to the T3 sequence. A trial AEM survey across T7 was flown in the September 2018 quarter to identify possible conductors.
