The grade values in each block in the model are geostatistically estimated using ‘Ordinary Kriging’ from exploration D f D D D drill assay results. The block models include already mined ore as well as remaining resources (to December, 2012). The three main contours shown are the smoothed outlines of grade blocks averaging 0.1, 0.3 and 0.6 percent copper on Map 2, and 0.1, 0.3 0 72 f 0 0 DD 0 56 and 0.6 grams per ton gold on Map 3. These contours display the grade distribution at an elevation most representative of the ore zones. In the core of Mount Polley centred on the Springer zone the contours are at an elevation of 1,000 metres (a.s.l.); in the 0 D 0 , D D D 1 , D D 0 4 0 4 Northeast zone (Wight pit) the contours are at an elevation of 900 metres (a.s.l.). This is roughly equivalent to 100-200 metres below the pre-mining topography. Patterns of grade distribution at deeper levels may be different in detail but are generally D 0 2 LTrpd1 2 8 8 conformable. The ‘Limit of elevated Cu, Au mineralization’ contour is less rigorously defined, based on assay results from exploration drilling, trenching and mapping. , D D , 5 D 5 LTrpmdu ² D LTrpkm D D (Kriging is a geostatistical estimation method that infers the value of a random field at an unobserved location from observed samples at known locations.)
