RESOURCE ESTIMATES In June 2006 the Company announced Estimate “M”, a block model estimate using all holes drilled up to February 15, 2006. The estimate was calculated by Micon International using the same database as was used for the polygonal estimate released on April 20, 2006. The summary table below is at a cut-off of 0.3 g/t gold.
* Gold-equivalent assumes equivalence of 75 units of silver to one unit of gold. Nature of Estimate This is a block model estimate incorporating holes drilled up to February 15, 2006. This estimate was prepared by Micon using ordinary kriging of 6 x 6 x 6 metre blocks. The estimation of grades was constrained by models of the mineralized zone created by Kimber staff using geological information and grade distribution. A mappable boundary to gold distribution is the 0.1 g/t contour. This was used to constrain gold distribution. A seperate boundary to silver mineralization was created at a grade of 35 g/t silver. The influence of the highest grade samples was limited by capping of gold and silver grades at 40.3 g/t and 1,052 g/t respectively.
