Ann: Weekly Drilling Update - Red Gully North-1, page-20

The targets are in two sections Upper Cattamarra Coal Measures and the Lower Cattamarra Coal Measures. The former being the D Sands in GGW-1 and RG-1.
The DMP report I have on GG-1 has porosity at 8% (minimum requirement) but has good permeability at 70mD. It does not differentiate between the two coal measures so we do not know what the untested section (Lower Cattamarra) holds.

The flow rates shown in the Corp. presentations show an aggregated flow rate of 16mmcf/d (GG-1 drill stem testes). Could be now down to 50% of that.
