Technical Report for the Maricunga Gold Mine - Kinross Gold

Kinross Gold CorporationMaricunga Mine Technical Reportthere is no significant difference and therefore the density assignment will remain the sameas in previous models. In addition, a review of the data shows that there is insufficient dataat this time to produce a spatial density model. Because the variation in the density valuesby redox code is not significant within the redox type, a mean density value is consideredreasonable.At Pancho the density values were coded using the newly interpreted oxidation surfaces.The statistics were calculated and compared with the previous model. It is, as in the case ofVerde, considered reasonable to use a mean density value in the blocks. Table 17-11 showsthe comparison between the original model and the model updated in 2007.Table 17-10: Density Measurements and Oxidation Level for VerdeOriginal Values2007 ChecksCode Mean Mean No. Data Min.

The modelwas manually reviewed in plan and section using Vulcan visualization tools. Visualinspection did not identify any errors in the model.17.5 Resource ClassificationThe mineral resource estimates for Verde and Pancho have bee prepared and classified inaccordance with the Canadian Institute of Mining, Metallurgical and Petroleum’s (“CIM”)88
