Kangaluwi Copper Project Update
First systematic drilling at the Chisawa Prospect of the 100% owned Kangaluwi Copper Project returns significant drill results
RC drilling returns substantial mineralised widths and grades from surface including: 14m at 1.52% copper, 12m at 1.36% copper, and 10m at 1.23% copper
Mineralisation remains open along strike and at depth
75% of the estimated total prospective strike length of the greater Kangaluwi project remains to be drill tested
Zambezi Resources Limited ("Zambezi" or the "Company") (AIM: ZRL; ASX:ZRL) today announces progress on its 100% owned Kangaluwi Copper Project.
The 2008 drilling campaign has been underway since May with up to 6 rigs on site and to date, approximately 26,000 meters of drilling has been completed so far this season. Further encouragement has been received from the first systematic RC drilling ever conducted at the Chisawa Prospect, which is located 2.5km to the south east of Zambezi's flagship Kangaluwi Prospect.
New RC drillhole intercepts from Chisawa include: 14m at 1.52% copper, 12m at 1.36% copper, 10m at 1.23% copper, and 14m at 0.65% (Table 1). Further assays are awaited to confirm strong zones of visual mineralisation observed in drilling. The mineralised zone remains open down dip and along strike to the east and west.
Mineralisation at Chisawa consists of chalcopyrite, bornite, malachite, azurite and secondary chrysocolla in the oxide zone. The host sequence consists of sheared metasediments, metavolcanics and a late stage, conformable coarse grained felsic pegmatite. Mineralisation is hosted within strongly foliated garnet-quartz-biotite-muscovite schist and feldspar-quartz-muscovite-kyanite pegmatite. Mineralisation dips moderately to the south west at approximately 30-40o and occurs within the sheared southern limb of an overturned ESE-plunging regional synformal fold.
Initial drilling at Chisawa targeted surface malachite mineralisation coincident with a >250ppm copper in soils geochemical anomaly over a north west - south east trending strike length of 7.2km. The significant results reported here come from the core of this anomaly which consists of a 3.1km strike length at >1000ppm copper in soils. The soil geochemistry conforms to a mapped and interpreted lithological and structural corridor. A strong correlation between the >1000ppm Cu contour and higher grade copper mineralisation is evident in the RC drilling. Drill testing of this zone to date is via widely spaced drill sections with a nominal distance between sections of 200-400m.
The greater Kangaluwi project covers in excess of 28km of strike length and detailed drilling has tested only approximately 3.5km strike length to date at Kangaluwi. At the neighbouring Chisawa prospect, drilling has sparsely tested only approximately 3.5km strike length. 75% of the estimated total prospective strike length of the greater Kangaluwi project remains to be drill tested.
Commenting on the announcement, Julian Ford, Managing Director of Zambezi Resources, said: "These excellent drill results from Chisawa over a 2km strike length confirm our opinion that the Kangaluwi Copper Project has the potential to develop as a world-class copper asset and a company-making project. The first two project areas we have tested namely Kangaluwi and Chisawa have both shown consistent mineralisation widths and grades at a favourable 30 to 40 degree angle of dip, with mineralisation starting at surface and defined down to a depth of at least 200 metres. We now have drill road access into most of the remaining priority target areas contained within the total strike length of 28km. To date only 25% of the surface-defined geochemical anomaly has been drill tested."

Coordinate system ARC50 UTM Zone 35S. Mineralised intervals calculated on basis of lower cutoff of 0.3%Cu, minimum mineralised interval of 0.5m, maximum consecutive internal waste of 2m. Mineralised intervals ≥ 3m% copper reported in table. Mineralisation dipping to south at approximately 35°. Mineralised widths reported on downhole basis, true width approximately downhole width x 0.98. Azimuths reported on ARC 1950 grid. UTM grid north = 354.5° magnetic. CHSRC prefix denotes RC drillhole. * Results for these holes were announced on 7 Dec 2006, but are reported here based on the current cutoff and width parameters as defined above. |

ADDITIONAL INFORMATION
Zambezi is listed on London's AIM market and the Australian Securities Exchange (ASX & AIM Ticker: ZRL) and currently has two main projects, Cheowa and Kangaluwi. Zambezi is one of Africa's most active exploration companies with a large, in-house, exploration execution capacity. The company is focused on discovering and developing large Copper-Gold projects in southern Zambia. At Kangaluwi, which is 100% owned, Zambezi is conducting extensive exploration drilling, as the company believes that the Kangaluwi project has the potential to be a world class open pit copper deposit. The 2007 drilling campaign initially focused on 3km of strike length at Kangaluwi, which was later narrowed down to an 800m section drilled to a 50m by 50m pattern. The company chose to intensively drill a small area in order to evaluate the possible economic potential of the mineralisation. Due to the encouraging results from this drilling the company has decided that the mineralisation has sufficient potential to justify a much more extensive drilling program at Kangaluwi and on the remaining five zones identified. The company also has entered into two Uranium Joint Ventures on approximately 50% of its tenement area, one with Rio Tinto and the other with Lithic Metals and Energy.
