Executive Chairman of Union Jack, David Bramhill, commented: "The net revenues exceeding US$1,000,000 within a relatively short timeframe is financially transformational for Union Jack.

"Our acquisition of further interests in Wressle over the last couple of years from just 8.33% to being the major equity holder with 40% is now showing material results and gives us increased confidence that the Company is set to deliver on its aim to become a self-sustainable entity in due course.

"Union Jack has four cash generating projects within its balanced portfolio and revenues for year end 2021 are guaranteed to eclipse those reported upon in 2020 and for the six months ended 30 June 2021.

"We believe that Wressle holds considerable further upside and we look forward to reporting on progress in due course."
