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. Given the success of the drilling programme to date, the current delineation diamond drilling Diamond Drilling is a highly specialized industry used for mineral exploration around the world. 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 program has been expanded from 20,000 metres to 25,000 metres and 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 "A Feasibility Study" is an episode of the original The Outer Limits television show.

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 cut-off Anesthesiology The point at which elongation of the carbon chain of the 1-alkanol family of anesthetics results in a precipitous drop in the anesthetic potential of these agents–eg, at > 12 carbons in length, there is little anesthetic activity, 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 ACA - Application Control Architecture Howe International Limited (a copy of which is available on SEDAR SEDAR System for Electronic Document Analysis and Retrieval SEDAR Southeast Data, Assessment, and Review at www.sedar.com or the Company's website at www.africancopper.com). RSG Global Pty Ltd., an independent consultant to African Copper, is completing a new resource estimate using the results of historic and current drilling. Results to date have reinforced previous data and provided new geological interpretations of the controls on mineralization within the broad breccia packages.

African Copper expects to complete detailed cost estimates and new resource estimations for the Dukwe project in the first half of 2006. The Company's other interests are the 4,000 sq km Matsitama exploration concession adjacent to Dukwe, which contains the Thakadu-Makala deposits in addition to a further 9 high priority drill-ready targets and 35 lower priority targets. African Copper has approximately 52 million shares outstanding.
