Wressle - Receipt of Planning Approval for Further Development

Union Jack Oil plc (AIM: UJO, OTCQB: UJOGF), a UK and USA focused onshore hydrocarbon, production, development, exploration and investment company is pleased to announce that planning consent has been received from North Lincolnshire Council for the further development of the Wressle well site.

The approved works will include extending the existing site to accommodate the drilling of two new wells, construction of gas processing facilities and an underground gas pipeline to connect Wressle to the local gas distribution network.

The Wressle field is located in onshore licences PEDL180 and PEDL182, situated on the western margin of the Humber Basin, North Lincolnshire.

Union Jack holds a 40% interest in the Wressle development.

David Bramhill, Executive Chairman of Union Jack, commented:

"I am delighted that the joint venture partnership has received the planning consent to continue development of Wressle, which will increase oil production and monetise the associated gas from the field, resulting in zero routine flaring at site.

"This positive decision represents to Union Jack a significant domestic production growth opportunity at our robust and reliable flagship Wressle project and for the UK provides economic and environmental benefits compared to imports on which the UK is becoming increasingly reliant.

"I look forward to updating the market further as the Wressle partners progress the field development."
