73koz may seem like not a large increase but this may be due to the company using such a high cut off grade. A cut off grade of 3.0g/t was used when usually a company may only use a cut off grade of 1.0g/t. This will greatly reduce our overall JORC resource, but doesn't mean that there isn't more gold there. Just at a lower grade

"A lower cut-off grade of 3.0g/t Au Eq was applied to reflect the mine cut-off grade estimated for the financial modelling in the 2013 prefeasibility study. It is important to note the previous 2004 resource was quoted with no cutoff, which demonstrates the robustness of the current JORC 2012 resource estimate."
