Marginal gold cut-off grades are approximate, based on material type weighted average. 2. The quantity and gold grade of reported Inferred resources in this estimation are uncertain in nature, and there has been insufficient exploration to define these Inferred resources as an Indicated or Measured mineral resource. Further exploration drilling is required to determine whether they can be upgraded to an Indicated or Measured mineral resource category. 3. The Measured and Indicated Mineral Resources are inclusive of those Mineral Resources modified to produce the Mineral Reserves.The Lefa Gold Mine estimated Measured and Indicated mineral resource as at 31August 2009 is 119.0 Mt, at average gold grade of 1.2 g/t, for contained gold of4.6 million ounces. Furthermore, the estimated Inferred mineral resource is14.1 Mt, at average gold grade of 1.3 g/t, for contained gold of 0.6 millionounces. These combined mineral resources of 5.2 million ounces are not mineralreserves and do not have demonstrated economic viability.The Measured and Indicated mineral resource total has decreased by 0.5 millionounces to 4.6 million ounces and the Inferred mineral resource has decreased by0.7 million ounces to 0.6 million. Since March 2008, mining depletion wasapproximately 0.3 million ounces. In total, mineral resources have decreased by1.2 million ounces, from the 6.4 million ounces announced in March 2008 to 5.2million ounces. After adjusting for actual depletion, the total reduction is0.9 million ounces, or 14%.Soci? Mini? de Dinguiraye (SMD), Crew's subsidiary in Guinea, has recentlyrevised its mineral resource estimation parameters, following a more thoroughreview of the Lero-Karta and Fayalala mineral deposits and review ofreconciliation between mining depletion and depletion in the geological model.As some of the previously identified mineral resources were extending at depth,SMD further constrained the main LEFA Corridor mineral deposits with a USD1000/oz gold price optimised pit shell. Consequently mineralisation previouslyincluded in the estimates has been excluded.The drilling in the Firifirini and Camp de Base mineral deposits increasedtonnage in the Measured and Indicated categories mainly due to reclassificationof the Inferred mineral resource. The mineral resource definition drilling in2008 down dip of known mineralisation on the Camp de Base structure of theLero-Karta deposit, continued to return broad zones of reasonable grademineralisation and also brought in additional tonnage.Higher average gold price, (i.e. the USD 1000/oz gold price optimised pit shell)resulted in the mineral resources being reported at lower cut-off grades.Previously, only Fayalala was reported at a cut-off grade of 0.60 g/t for allmaterial types with the rest of the Lefa Corridor deposits reported at 0.70 g/t.The mineral resources are generally now reported at a lower cutoff grade of0.40 g/t for saprolite and 0.50 g/t for laterite and fresh material types.The mining of the higher grade at Lero and Lero South pits, whereby 2.5 Mt at agrade of 2.3 g/t were mined during the reporting period, also contributedsignificantly to an overall reduction in mineral resource grade in this area,from 44.5 Mt at 1.9 g/t to 42.7 Mt at 1.5 g/t.The Firifirini and Toume Toume deposits remain open along strike and down dipand, as previously announced, are part of a new style of mineralisation that haduntil that time not been recognised within the Concession. These areas were alsothefocus of mineral resource definition drilling during 2008, with a combinedmineral resource total increase from 5.7 Mt at 2.4 g/t to 8.0 Mt at 1.5 g/t.There was no regional drilling conducted during the reporting period. However,ongoing geochemical soil sampling, mapping and trenching continued to occur anda re-evaluation of the existing concession has taken place to enable moreadvanced exploration activities to recommence later in 2010. The Kobedara regionmineral deposit was reassessed and removed from the mineral resource estimate,with further work planned in the future to assess the potential there.The drilled out areas of the old leach pads are included in the mineral resourceestimate, where 2.3 million tonnes have so far been defined from in-filldrilling, returning approximately 57,000 ounces. Close to 7 million tonnes stillremain to be drilled, providing further potential.Bill LeClair, President and CEO of Crew commented:"A critical independent reviewof our mineral resources based on the reconciliation results has resulted in ageological model that is extremely robust. Thus, while the result has been aslight decrease in the geological resource net of mining depletion, it presentsa solid case for Crew to continue expanding the mineral resources. At just over5.0 million ounces in total mineral resource, this places LEFA in the ranks ofworld-class gold deposits. The Company is confident that continuing explorationwill provide further increases to the mineral resource and reserve inventory."For further information on the resource data please refer to ourwebsitewww.crewgold.com
