Ann: Walyering-5 Gas Discovery, page-46

While drilling to total depth, additional gas sands were encountered with the well yet to observe
a water contact. The W5 A Sand sits some 233m TVD ss higher than W1 and 145m TVD ss higher
than W4, indicating the potential for a larger than expected gas column and corresponding
resource.

In STX announcement above they have mentioned potential for a corresponding resource, the map you have put up has the other prospects in 447 approx 20km away. Perhaps there is more prospects closer to Walyering-5 in the southern section of 447 as well.
