Kalahari Copper Belt, Botswana
The Kalahari Copper Belt is one of the world’s most exciting, emerging copper producing regions and our landholding, which extends over the central and western portions of the belt, provides substantial exploration upside.
A maiden Inferred Mineral Resource at A1, which is located 20km ENE of the Motheo processing plant, of 5.6Mt at 1.3% copper and 10g/t silver was established during the year. We also completed drilling programs to test the extent of the A4 orebody, which remains open in all directions, and a new footwall target that has been identified at T3. The results from these programs are currently pending.
Several drillholes within the Motheo hub, which is broadly defined as the economic trucking distance to the processing facility, were designed to test structural settings similar to those that host the T3 and A4 ore bodies. While no significant mineralisation was intersected, the geological information obtained has been incorporated into our 3-D basin model.
Our understanding of the depositional environment and structural controls that influence economic mineralisation continues to grow and will be further enhanced by the recent completion of an Airborne Gravity Gradiometry (AGG) survey over the Ghanzi-Ngamiland block, which is host to all the known copper deposits in the Kalahari Copper Belt. A separate AGG survey was also completed over the Okwa block, a large igneous intrusive complex which lies to the South of the Kalahari Copper Belt.
