Drilling Report
(Thomson Reuters ONE) - AIM RELEASE12 November 2009 Discovery Metals Limited Boseto BFS Update Plutus Infill Drill Hole Results and Further Quirinus Exploration ResultsHighlights§ 58 new infill diamond drill holes within the existing Plutusresource envelope have returned assays that continue to confirm thecontinuity and predictability of copper - silver mineralisation§ Significant assay results include:o Hole PSDD813 9.0 m (at) 2.5 % Cu & 22.8 g/t Ago Hole PSDD861 5.0 m (at) 2.4 % Cu & 25.2 g/t Ago Hole PSDD824 10.0 m (at) 1.8 % Cu & 11.6 g/t Ago Hole PSDD858 9.0 m (at) 1.7 % Cu & 20.2 g/t Ago Hole PSDD832 10.0 m (at) 1.6 % Cu & 14.5 g/t Ago Hole PSDD882 11.8 m (at) 1.4 % Cu & 14.6 g/t Ag * Infill drilling confirms the potential for higher grade zones within the Plutus Resource§ Drilling results form part of the Bankable Feasibility Study('BFS') to upgrade portions of the Plutus Prospect into the IndicatedResource category. Updated resource expected December 2009§ Diamond drilling at the Quirinus Prospect confirms the presence ofcopper-silver mineralisationPlutus Infill DrillingDiscovery Metals Limited ('Discovery Metals' or 'Company') (ASX/BSE: "DML") (AIM:"DME")announces the assay results from the most recent 58 infill diamonddrill holes at the Plutus Prospect at the Company's 100%-owned BosetoCopper Project located in north-west Botswana (Figure 1).The Plutus infill drilling programme forms part of the Boseto Copperproject BFS and the latest results confirm the potential for highergrade zones. As with all other prospects at the Boseto CopperProject, the Plutus Mineral Resource remains open at depth.Details for all 58 drill holes are reported in Table 1 and aselection of results are displayed in plan in Figure 3 and section inFigures 4, 5, 6 and 7.The Plutus Prospect currently contains an Inferred Mineral Resourceof 15.9 Mt (at) 1.6% Cu and 16.4 g/t Ag at a cut off grade of 0.6% Cu(Figure 2).The recently upgraded total mineral resource for the Boseto CopperProject, reported in accordance with the Australasian Code forreporting of Exploration Results, Mineral Resources and Ore reserves(the JORC Code, "2004 Edition") is:60.4 Mt (at) 1.4% Cu and 19.5 g/t Ag at a cut off grade of 0.6% Cucontaining approximately 846 kt Cu metal and 38 Moz silver.Quirinus DrillingAssay results have also been received from four diamond drill holesat the Quirinus Prospect (Figure1) which is located within 15kilometres of the Boseto Copper Project. The assay results havesuccessfully confirmed the presence of copper-silver mineralisationin the portion of Quirinus that has now been drill tested. Thesedrill holes cover a strike length of approximately 600 metres and afurther 12.8 kilometres of strike length remains to be explored inareas where significant anomalous copper has been detected in soilsat Quirinus.Details for these four holes are presented in Table 2 and a selectionof these holes is displayed in plan in Figure 8 and in cross sectionin Figure 9.In June 2008, Discovery Metals reported the results from threereverse circulation drill holes that were drilled to test a largearea of anomalous copper. The three reverse circulation drill holesall intersected copper-silver mineralisation. The Company thencompleted four diamond drill holes in the northern limb of theQuirinus Synform (Figure 8).The Company plans an additional diamond drilling programme in Q42009. Drilling will focus along the full 13.4 kilometres of strikelength currently identified as being prospective.Implications for Boseto ProjectThe Plutus infill drilling programme has been planned to upgradeportions of the Plutus Resource into the Indicated Mineral Resourcecategory. The infill programme covers areas of the Plutus MineralResource believed to be amenable to open pit mining.On completion of the infill drilling programme and receipt of finalassay results (in October 2009), a new Mineral Resource will bere-estimated and announced in December 2009.The data from these 58 holes is consistent with previous results andconfirms the continuity of copper-silver mineralisation over anextensive strike length (exceeding 10,000 metres in the combinedPlutus and Petra Mineral Resource areas).The four diamond holes drilled at Quirinus confirm the presence ofcopper-silver mineralisation similar to that found at the nearbyZeta, Plutus and Petra prospects.Anomalous copper in soils has been identified at Quirinus in threeareas over a combined strike length of 13.4 kilometres. To date,drilling has only been carried out in a small portion of the northernzone of anomalous copper results over a strike length ofapproximately 1,000 metres.Discovery Metals' Managing Director, Brad Sampson commented, "Theprogression of the Plutus infill drilling programme representsimportant and systematic progress towards the completion of theBankable Feasibility Study for the Boseto Copper Project next year.The infill drilling campaign is designed to upgrade portions of thePlutus Prospect into the Indicated Resource category and we lookforward to announcing an updated resource estimate by the end of2009""At Quirinus, we have now confirmed this Prospect has significantpotential and further drilling will commence in December to discoveradditional Mineral Resources that may add value to the Boseto CopperProject", he added.Boseto Project BackgroundDiscovery Metals' Boseto Copper Project (100% owned) is located innorth-west Botswana, approximately 80 kilometres south-west of thetown of Maun, within the district of Ngamiland. A seven tenementpackage was granted to Discovery Metals in September 2005 andfieldwork on this tenement package commenced in October 2005. TheGovernment of Botswana approved the Company's renewal of thesetenements in September 2008 and all prospective areas were retainedby the Company. In June 2008, Discovery Metals was granted anadditional seven tenements extending from the south-west boundary ofthe original 2005 granted tenements through to the Namibian border,adding 5,700 km2 to the area held under prospecting licenses, tobring the total current tenement area to 10,100 square kilometres. The outer limit of the exploration licence area starts approximately60 km south-west of Maun and stretches in a south-westerly directionfor approximately 300 km to the Namibian border.The Boseto Copper Project is located within a belt of significantcopper-silver mineralisation that extends from the well known andmore highly developed Zambian Copper Belt across north-west Botswanaand into Namibia. The poorly explored and undeveloped portion ofthis belt in north-west Botswana is known as the Kalahari CopperBelt.Copper in the Boseto Project area occurs predominantly in chalcocite,with minor amounts of bornite and other copper sulphides present. Atshallow depths, malachite and chrysocolla exist in significantproportions within some areas of the mineral resource.The total Mineral Resource for the Boseto Copper Project, reported inaccordance with The Australasian Code for Reporting of ExplorationResults, Mineral Resources and Ore Reserves (The JORC Code, "2004Edition") at a cut off of 0.6% Cu is:60.4 Mt (at) 1.4% Cu and 19.5 g/t Ag containing 846 kt copper metal and 38 Moz silver Consisting of:Measured and Indicated Mineral Resource of 11.7 Mt (at) 1.5% Cu and 22.9 g/t Ag and, Inferred Mineral Resource of 48.7 Mt (at) 1.4% Cu and 18.7 g/t AgA Pre-Feasibility Study for the Boseto Copper Project was completedon time and on budget in July 2008.Discovery Metals is currently undertaking a Bankable FeasibilityStudy for the Boseto Copper Project which is planned for completionin March 2010.Further information on the Company is available on its website:www.discoverymetals.com.auCompetent Persons StatementThe information in this report that relates to Exploration Results isbased on information compiled by Mr Fred Nhiwatiwa who is a Member ofthe Australasian Institute of Mining and Metallurgy (MAusIMM).
