Grades for copper, gold and silver were estimated within the mineralization wireframe using Ordinary Kriging after compositing the assay intervals to 6 metre down-hole lengths within the mineralized wireframe. Gold grade estimates were further constrained with a probabilistic model to prevent over-projection of the higher grades into lower grade areas.Search ellipsoid dimensions and orientations were determined on structural geological and geostatistical information. An average density (specific gravity) value of 2.825 was assigned to blocks based on 592 density measurements provided by Sunridge.
