Coal Quality

A total of five hundred and thirty four (534) holes were used to model the quality of coal resources and sub-samples have been combined to represent the qualities per seam in the deposit. 21 of the boreholes were used for the final quality model of the Palmietkuil Target Area. Drill holes were classified as valid points of observation for determining resource status if the following criteria were met:
· The entire seam was cored;
· Core recovery for the seam was ≥95%;
