DST operations to commence early May

Empyrean Energy plc ("Empyrean" or the "Company"), the oil and gas development company with interests in Australia, Indonesia and the United States, is pleased to announce the following update on the Wilson River-1 well:

The JV partners in The Wilson River-1 have all elected to participate in the upcoming Drill Stem Test (DST) operations previously advised in RNS dated 2 April 2025.

Flooding in Queensland, Australia and in particular in the Eromanga region since drilling operations completed in late March have necessitated the JV to allow the drill pad and surrounding access tracks to dry and where necessary be remediated to ensure safety and complete access.

DST operations are now due to commence in early May.

                Empyrean CEO, Tom Kelly, stated: "The testing program has been refined and equipment has been sourced. Whilst there have been some minor remedial work required due to the flooding, we are in good shape to commence testing in early May".

The information contained in this announcement has been reviewed by Empyrean's Technical director, Gaz Bisht, who has over 35 years' experience as a hydrocarbon geologist and geoscientist.
