Thanks Crackity.
Ascalon reserve in the Bonaparte Basin is just south of Bayu-Undan and to the west of the new Bonaparte gas reserves in the Santos-Beach partnership. You can see Ascalon on the map link provided by Crackity.

OXX interests in Northern Carnarvon Basin (Winchester) are just northwest of Corvus (25km), and larger holdings further to NW also.
(25% stake in project carried by SANTOS for exploration).

Hopefully a little more exploration in the OXX catchments is on the cards.... Perhaps Octanex will raise again from the ashes of Ophir.
OXX is now a SPEC stock for me and worth a punt again.
