Zambezi Resources Limited (ASX: ZRL)
Kangaluwi Copper Project Update
- 100% owned Kangaluwi prospect confirmed as major new discovery of copper mineralization in Southern Zambia
- 28km of prospective strike length identified in immediate area. Drilling to date has tested only 10% of the estimated prospective strike length
- Initial Metallurgical Test results indicate sulphide recovery in excess of 95% for copper from conventional flotation
Zambezi Resources Limited (?Zambezi? or the ?Company?) (AIM: ZRL; ASX:ZRL) today announces progress on its 100% owned Kangaluwi Copper Project which is the main focus of the 2008 drilling campaign.
The greater Kangaluwi project covers in excess of 28km of strike length. The company intends to test the majority of this strike length in the 2008 and 2009 field seasons.
The 2008 drilling campaign is now well underway with 6 rigs on site and 15,500m drilling completed so far this season. Further encouragement has been received from recent drilling with excellent continuity both down dip and along strike.
The new independent analytical laboratory being established in Lusaka in Zambezi?s sub-leased warehouse is expected to be fully operational by the end of August and is expected to substantially reduce assay turnaround times.
Preliminary metallurgical testwork on composite 2007 drill core from Kangaluwi has indicated favourable metallurgical characteristics. The ore is relatively soft with a Bond Mill Work Index of 11.5 kWhr/t, and a Rodmill Work Index of 8.9 kWhr/t. This is based on a single composite test. The first rougher flotation test showed recoveries in excess of 95% copper and silver which are the only metals expected to be of economic value for the Kangaluwi Project. A set of more comprehensive metallurgical tests will be undertaken commencing in September 2008.
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 recent intensive drilling program comprised a total of 19,928m of RC and Diamond drilling. Assay results from RC and Diamond drilling carried out in 2007 continue to return significant copper mineralisation over substantial widths in multiple zones (Table 1). The new results, which are additional to those already announced, include 4.78m at 1.86% copper from 78.67m, 5.72m at 1.26% copper from 104m, 8.72m at 0.93% copper from 43.28m, and 12.5m at 0.97% copper from 91.5m. These results further demonstrate the consistent mineralisation typically encountered at this discovery to date.
