question re crux upgrade, page-3

I think I mean the new found formation.

The 8 May upgrade announcement states:
"The increase in contingent resource liquids volumes results from the higher than expected ‘Condensate to Gas Ratio’ encountered in the sidetrack well."

But it does not specify that any part of the upgrade from best case of 55 Condensate (MMstb) to 65 Condensate (MMstb) is a result of field extension.

It does say:
Crux-2 ST1 has confirmed that the high quality Plover Formation sand seen in the Crux-2 well is present over the north eastern part of the Crux Field and has the potential to add significant additional further resources in the high case.

The whole thing is a bit open ended???
