Witvlei Copper Project
The Witvlei Copper Project covers five known copper deposits located over a region of 650km². North River is currently appraising 250,000 tonnes of previously defined historic resources and is aiming to quantify a resource base that will support a viable and sustainable operation. Data generated in 2008 by Kalahari Minerals from the drilling programme targeting three deposits – Malachite Pan, Okasewa and Christiadore, is currently being reviewed and analysed to determine the project’s viability.
Malachite Pan
A total of 388 RC holes have been drilled to date for 51,815m, 20 DD holes for 3,431.8m and 26 diamond tails, to extend previously drilled RC holes, for 2,745.3m. Mineralisation remains open and drilling continues with major copper intersections to date including:
- 24m @1.2% Cu
- 16m @1.9% Cu
- 15m @1.8% Cu
- 11m @3.0% Cu
- 16m @1.9% Cu
Okasewa
At Okasewa, a total of 228 RC holes totalling 36,290m have been drilled based on major copper intersections that were generated from 39 RC holes drilled in 2007, which included:
- 54m @1.5% Cu
- 51m @ 1.0% Cu
- 37m @ 1.8% Cu
- 34m @1.0% Cu
The additional RC drilling commenced in May 2008 and was completed in December 2008. This drilling concentrated on the NE and SW target zones. Assays are presently only available from the NE target with returned copper assays remaining extremely encouraging with highlights including:
- 108m @ 1.21%
- 35m @ 1.00%
- 21m @ 1.46%
- 22m @ 1.60%
A further 8 DD holes for 1,809.4m were completed in 2008 for metallurgical test work, which is presently underway.
Christiadore
A total of 32 RC holes totalling 4,434m have demonstrated major copper intersections including:
- 9m @ 2.5% Cu
- 7m @ 2.9% Cu
- 5m @ 3.7% Cu
A further 4,000m has been drilled at the Witvlei Pos prospect.
