Highlights

·    Well continues to produce under natural flow with zero water cut

·    Site upgrades ongoing

·    As at 22 April 2022, the Company's cash balances and short term receivables stand at in-excess of £7.05 million

·    Net revenues of £2.4 million registered to date during 2022, already comfortably exceed 2021 year-end unaudited revenues of in-excess of £1.8 million

Executive Chairman of Union Jack, David Bramhill commented: "The revenues from the Wressle development continue to highlight the sea change in the financial robustness of Union Jack, as the figures above illustrate.

"We are still in the early stages of the process of unlocking the significant upside potential at Wressle with the future monetisation of the natural gas at the Ashover Grit reservoir plus the substantial future revenue opportunity offered by the Contingent Resource present in the Penistone Flags reservoir that remains untapped.

"We also look forward to the publication in the near future by the Operator of its report on the various projects in which Union Jack is involved.

"Given the future prospects at our core projects at Wressle, West Newton, Keddington and Biscathorpe, the Board of Union Jack believes the Company remains on a material growth trajectory which augers well for the future of the Company and its shareholders."
