A detailed visual validation of the Planes and Colinas block models wascarried out in both sectional and plan views where grade interpolation into blocks was checkedrelative to composite values in drillholes. The checks showed good agreement between drillholecomposites and block model grades.See Figures 17.3, 17.4 and 17.5 for Planes deposit x-sections. See Figures 17.6 and 17.7 forColinas deposit x-sections.
