West Newton Permit Variation

 

Union Jack Oil plc (AIM: UJO, OTCQB: UJOGF), a UK and USA focused onshore
hydrocarbon, production, development, exploration and investment company notes
today's announcement from Rathlin Energy U.K. Limited ("Rathlin") regarding
the West Newton gas development project, located within PEDL183, onshore UK in
East Yorkshire.

Rathlin, operator of the licence, has been informed by the Environment Agency
("EA") that it has issued Rathlin the variation to the permit for the West
Newton 'A' Well Site to include a reservoir stimulation in the WNA-2
well, subject to certain pre-operational conditions. The recompletion works
are designed to overcome well bore damage that was sustained during earlier
drilling operations.

The Company believes that the planned recompletion of the WNA-2 well is a
low-cost and low risk means of further derisking the sub-surface element of
the West Newton project and gathering data to optimise future production
wells.

This key regulatory milestone clears a major hurdle in the path toward
development and eventual production at West Newton, strengthening Rathlin's,
and consequently Union Jack's, ability to advance its UK onshore assets within
a responsible environmental and social governance framework.

The Company is confident that West Newton will prove to be an important
strategic asset to the UK as the country looks to secure domestic energy
supply and affordable energy.

Union Jack holds a 16.665% interest in PEDL183.
