R a r e E a r t h E l e m e n t E x p l o r a t i o n P r o g r a m M a r c h - 2 0 1 3 W i n t e r - S u m m e r 2 0 1 2 P a g e | 107 19.1.6 Classification The Mineral Resources estimated for the REE deposit were classified according to the “CIM Definition Standards for Mineral Resources and Reserves” (December 11, 2005). IAMGOLD mandated the consulting firm G Mining Services to support the Niobec geology team in achieving and validating the 2012 resources calculation. These resources are classified according to the drill hole coverage and the REE mineralization continuity interpreted by the qualified person. The new <strong>drilling</strong> grid, 100m x 100m down to 350m below surface, define the rare earth elements hosting rock (C1). All limit, north, east, west and south, were intersected and the geometry of the ore body is trace on sub surface. From 350m to 700m below surface, is spaced by a <strong>drilling</strong> grid of 100m x 200m. The cylinder shape of the mineralized C1 can be, without confusion, extended at depth. With only a few holes going down to ±1200 metres, the REE zone is judged continuous in grade and still open at depth. Base on the actual knowledge of the REE zone, the indicate resource correspond to the first interpolation rules and are limited to the 9650 level (350m below surface) (Figure 30). From 350m the drill definition decreased and the resources were called inferred. Even if the block model was extended at depth, the resource calculations were limited to 700 metres below surface. At this stage, no reserves were defined for the REE zone. Figure 30: Resource classification, typical section view.
