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 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 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 "A Feasibility Study" is an episode of the original The Outer Limits television show. It first aired on 13 April, 1964, during the first season.

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).

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.
