Most commonly using wireline and core bits with diamond encrusted matrix. To drill holes to max depths of twelve thousand feet, for the recovery of core used in verifying mineral over 600 metres of strike extent at Mapanipani North is complete with a resource estimate expected at the end of January. Drilling of the central Mapanipani and the southerly Bushman areas is expected to be completed over the next eight weeks. The first 18 drill holes from the infill diamond drilling programme were reported in a press release dated 30 November, 2005. A further 4 holes are released below, with approximately 20 holes to be released over the next six weeks. - 3.41% copper over 4.43 metres, 3.47% copper over 2.39 metres and 3.18% copper over 3.65 metres demonstrate vertical continuity of high grade zones within broader intervals of lower grade mineralization Mineralization The process by which the body uses minerals to build bone structure.

Three discrete areas of mineralization occur within a 2,000 metre strike length: Mapanipani North, Mapanipani and Bushman. Drilling at Mapanipani North has been completed, with the six drills on site now concentrating on resource delineation at the central Mapanipani area. Results of the Infill Programme The results for the first 18 drill holes from the Mapanipani North resource area were reported previously. A further four holes are tabulated below. Selected intersections include: - 3.41% copper over 4.43 metres - 2.11% copper over 15.40 metres - 3.47% copper over 2.39 metres - 1.75% copper over 9.53 metres - 3.18% copper over 3.65 metres - 1.65% copper over 14.32 metres - 3.02% copper over 4.73 metres - 2.10% copper over 7.70 metres These intersections are contained within broader mineralized envelopes that typically return 1.07% copper over 30.07 metres, 0.62% copper over 76.16 metres, and 0.71% copper over 37.00 metres.

Locked Cycle tests are underway with results to be released shortly. The infill drilling has confirmed the broad geology and styles of mineralization encountered in historic drill holes. The first phase of the current drill programme is designed to cover the 600 metres of the strike extent of Mapanipani North to a depth of approximately 500 metres below surface. The drill holes reported below are generally for the upper portions of the mineralized zone, to a depth of about 400 metres below surface. The Mapanipani North resource area consists of multiple chalcopyrite chalcopyrite (kăl'kəpī`rīt, kăl`kōpī'rīt) or copper pyrites (pīrī`tēz, pə–), brass-yellow mineral, sometimes with an iridescent tarnish. lenses contained within the breccias and cataclastites of the Bushman Shear zone, a major regional North-South structural tear that defines the western margin of the Matsitama Fold Belt. The Mapanipani North mineralized zone remains open to the north, and truncated truncated adjective Shortened to the south by an oblique post-mineralization fault. Mineralization is characteristically massive to semi-massive to disseminated and associated with quartz-calcite healed breccias. Numerous periods of deformation and mineralization are noted. The current drill program is focussed along a 2,000 metre stretch of the shear zone, but mineralization has been drill tested by previous companies and shown to exist for a further 2,000 metres to the north of the current drill area, and for 1,000 metres to the south. A table showing the composite assay intervals for the diamond drill holes is attached to this press release. A plan map showing the location of historical holes and these holes is available on the African Copper website at www.africancopper.com. Cross sections of the drill holes reported herein are also available on the website.

Six drills are currently on-site completing a sulphide delineation drill programme. African Copper expects to commence construction of a mine at Dukwe in early 2006. The Company's other interests are the 4,000 sq km Matsitama exploration concession adjacent to Dukwe, which contains two known copper deposits and numerous base metal exploration targets. African Copper has approximately 52 million shares outstanding.
