African Copper Plc: Further High Grade Drill Results From Dukwe Project, Botswana

LONDON, UNITED KINGDOM--(CCNMatthews - Jan. 20, 2006) - African Copper Plc (TSX:ACU)(AIM:ACU)(BSE:African Copper) -

- The final delineation drill holes from the Mapanipani North lens have continued to show high-grade intercepts surrounded by broader intersections of lower grade material. The geological continuity of the broad mineralized package continues to be excellent.

- 3.54% copper over 9.33 metres in the footwall zone of mineralization at the northernmost section. This intersection is the most northerly hole drilled during the current programme and appears to coincide with the previously reported high grade footwall intersection 120 metres to the south (see press release dated 6 January 2006). The footwall zone remains open to the north and to depth.

- 3.49% copper over 14.50 metres from the hanging wall on the same section as the high-grade footwall mineralization reported previously (6.44% over 9.33 metres as reported in the press release dated 6 January 2006).

- 6.73% copper over 2.95 metres and 5.70% copper over 3.52 metres contained within a broader intersection of 0.92% copper over 86.62 metres.

- 4.57% copper over 3.05 metres and 3.53% copper over 3.20 metres contained within a broader intersection of 1.18% copper over 38.90 metres.

- At the northern end of the Mapanipani North lens 2.11% copper over 17.5 metres contained within a broader intersection of 1.00% copper over 69.30 metres. Six hundred metres to the south at the southern end of Mapanipani North a drill hole intersected 3.65% copper over 5.76 metres contained within a broader intersection of 1.08% copper over 37.35 metres. These results continue to demonstrate the geological continuity of broad mineralised zones.

The Dukwe deposit is known to exist over a strike length of 4,370 metres in five separately named sections which are continuous along strike except for slight displacements along post-mineral faults. The current 20,000 metre delineation diamond drilling programme is focusing on three of these sections covering a 2,000 metre strike length: Mapanipani North, Mapanipani and Bushman. The drilling programme is designed to increase the confidence of the resource estimate with the objective that Measured and Indicated Resources can be defined prior to the completion of a feasibility study for the sulphide portion of the orebody. The drill programme is being managed and supervised by RSG Global Pty Ltd., an independent contractor to African Copper Plc ("African Copper" or the "Company"). Metallurgical testing has confirmed that oxide, supergene and sulphide material can be recovered through conventional flotation to create a marketable concentrate (see press release dated 23 November 2005). Locked Cycle tests have been completed with results to be released shortly.

Mapanipani North

Drilling at Mapanipani North, which covers 600 metres of the 2,000 metre strike length being tested, is now complete and a resource estimate on this section is expected to be released shortly. The results from the following 12 drill holes are in addition to the 28 holes that have been previously released. (see press releases dated 30 November 2005, 7 December 2005 and 6 January 2006).

David Jones, CEO of African Copper, commented: "Delineation drilling at the Mapanipani North zone has been successful in demonstrating significant intersections of copper. The drilling also clearly exhibits that the broad mineralized packages can be traced along the length of the deformation zone and to depth. The Mapanipani North lens is open to the north and to depth. The deepest hole in the current programme cut the deposit at a depth of approximately 475 meters below surface providing the Company an opportunity to expand the Mapanipani lens."

A table showing the composite assay intervals for the final 12 diamond drill holes is set out below. A plan map showing the location of historical holes and these 12 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 Company's website.

Mapanipani and Bushman

With the current delineation drill programme at Mapanipani North complete the six drills on site are now being used to trace the copper horizon to the south at the Mapanipani and Bushman lenses. Results from this drilling will be released as they become available.

The present reserves at Dukwe are comprised of oxide and supergene material and are defined as a Probable Reserve of 5.1 million tonnes grading 1.85% copper to a maximum depth of 175 metres below surface. Beneath this reserve lies a further Inferred Resource of 13.0 million tonnes of sulphide material grading 3.85% copper (using 1.5% cut-off and 2 metre minimum mining width). These reserve and resource estimates are contained in a technical report entitled "Technical Report on the Dukwe Copper Project and Matsitama Prospecting Licences Botswana, Africa" dated May 5, 2005 prepared by ACA Howe International Limited (a copy of which is available on SEDAR at www.sedar.com or the Company's website at www.africancopper.com).

Note: The intersections shown in the table above are not true widths since all holes are drilled to the west-northwest or east-southeast with collar inclinations of -55 degrees to -65 degrees into the mineralized zone that dips to the east-southeast at -80 degrees to -90 degrees. Samples of half core are cut and placed into sealed bags on the Dukwe site under the direct supervision of RSG Global Pty Ltd. These are transported weekly by commercial carrier to Johannesburg. All sample preparation and analyses are completed at ALS Chemex laboratories in Johannesburg (ISO 17025 accredited and independent of African Copper and RSG Global Pty Ltd.). Copper assays are completed using standard preparation of crushing to 70% less than 2 mm followed by splitting and pulverizing to 85% less than 75 micron. Analyses are generally completed utilizing 27 element four-acid ICP-AES in addition to a four-acid ore-grade element digestion followed by ICP-AES. Any overlimit analyses are reanalyzed using an ore-grade four-acid digestion with AA or ICP-AES finish. QA/QC procedures included the submission by RSG Global Pty Ltd. of systematic duplicates, blanks and both low-grade and high-grade standard samples within the sample batches submitted to ALS Chemex. Control samples comprise 20% of all samples submitted. No referee analysis has yet occurred. The results of the RSG Global Pty Ltd. QA/QC programme for copper analyses have been reviewed by RSG Global Pty Ltd. and Mr. Joseph Hamilton, P.Geo.
