• Future Actions <br />• Further checking and validation of data in the geological database is required. <br />CCC should re- evaluate the ASG data by plotting ASG by seam and having +/ -50 <br />samples checked by the SGS laboratory <br />• CCC should request Mincom to correct inconsistencies in MineScape surfaces. <br />• Improvements could be made using statistical techniques to evaluate the continuity <br />of the data. TS will undertake this evaluation using suitable closely spaced drill hole <br />data. <br />The statistical evaluation may lead to an improved understanding of the definitions <br />of resource categories. CCC and TS should consider whether to re- define <br />resources and whether to re -model the thickness and quality data. <br />• CCC should consider whether to sample seams that are <2 ft thick. <br />CCC should use the updated resource model to re- evaluate the mine plan with <br />margin ranking. <br />• CCC must develop written data entry/transfer procedures for all CCC drill hole <br />databases as soon as practically possible. <br />• 0 CCC must develop documented procedures for use when archiving or exporting <br />data from its Geological model. <br />• <br />BR3273: FINAL Version: 1 <br />RIO <br />TINTO <br />rerhnical Scrvicrs <br />
