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 central Mapanipani zone has shown intersections of further high-grade mineralization at a vertical depth between 325 metres and 375 metres. Drilling intersected 5.15% copper over 6.90 metres and 3.23% copper over 10.13 metres contained within a larger intersection of 1.56% copper over 61.69 metres. Approximately 120 metres to the south of this intersection, a drill hole returned 4.03% copper over 4.10 metres contained within 1.08% copper over 48.50 metres. These results continue to demonstrate the semi-massive nature of mineralization that is contained within the broader, lower grade breccia package. This mineralization remains open to depth. The summary results for the delineation drillholes reported are shown in the table below. Location plan maps and cross sections are available on our website at www.africancopper.com.
