  The prospect of further expanding the total resource at Discovery Metals’ Maun Copper Project in northwest Botswana has been enhanced by more encouraging results from drilling at the Plutus prospect.Discovery said a 5.5km long zone of copper-silver mineralisation at the Plutus prospect had produced further positive results from an ongoing drill program, boosting the potential of this prospect to be potentially mineable via an open pit operation.The Plutus prospect copper-silver mineralisation occurs 10km north of the main Inferred mineral resource on the Maun Project at the Zeta Prospect (27.1Mt @ 1.3% Cu and 21g/t Ag at a 0.6% Cu cut-off) and 5km northeast of the Petra Inferred mineral resource (4.5Mt @ 1.1% Cu at a 0.6% Cu cut-off). Drilling at Plutus has concentrated on defining mineralisation able to be extracted in an open pit with the majority of drill holes less than 120m vertical depth.Discovery’s Managing Director, Jeremy Read said drilling completed by Discovery throughout 2007 had already increased the total copper resources on the company’s Maun Project by 58 percent to 31.6Mt @ 1.3% Cu at a 0.6% Cu cut-off (JORC Inferred).“If an Inferred mineral resource can be defined at the Plutus prospect, this resource will add significantly to the existing Maun Project resource base,” Mr Read said.“The recent drill results show that the Plutus mineralisation is very similar to the Zeta mineralisation in that there appears to be a high-grade zone of mineralisation within a broader envelope of mineralisation grading around 1% Cu,” he said. “The drilling we are doing at Plutus is quite broad spaced, on 500m sections, but we are starting to get a feel for where the high-grade zones are and these zones seem to grade in between 1.6 and 2.3% Cu.“Infill drilling will be required at Plutus to more accurately define where the higher-grade mineralisation is, but there seems to be emerging a higher-grade zone in the north of the prospect and one towards the south of the Plutus mineralised zone,” Mr Read said.
