Ann: STX Acquires Interest in Highly Attractive Perth Basin Block, page-54

hi psi
maybe AWE were constrained in making a move because they are subject to a takeover offer.
to me these are the key points of the announcement (STX have done their own work)

"Strike’s prospect evaluation from the existing 3D seismic within the yet to be intersected Kingia-High Cliff sequence (Waitsia), has yielded an extremely attractive, top tier, conventional structure in a combined dip and fault closure. Presence of material hydrocarbons is indicated by structurally conformable amplitudes and associated flat-spots. Subject to confirmation from additional model calibration, the Kingia-High Cliff sands are believed to be present with thickness and porosity development that is interpreted to be similar in quality to that in the adjacent Waitsia gas discovery. Initial views of the prospect are that it would be more than sufficient in size to support a stand-alone development."
