"Welchau-1 resumption of flow testing and shallow gas prospect drilling program commencing in January 2026. Anshof near field oil appraisal in second half of 2026."

"Drilling targeting large increase in gas and oil production from low-risk prospects, as well as Welchau flow potential."

Key points:

Planning and contracting of services are ongoing for the resumption of flow testing of the Welchau-1 well, the drilling up to three shallow gas wells (HOCH-1, GOLD-1, SCHOE-1) and an Anshof near field oil appraisal well (SGB-1) in the ADX-AT-I and ADX-AT-II exploration and production licences in Upper Austria (refer to Figure 1).

• Drill program targeting large production increase from low-risk gas shallow gas and nearfield oil drilling.
• Welchau flow testing to recommence in January 2026 due to positive court ruling.
• Shallow gas drilling to commence in February 2026 targeting biogenic gas (99% methane)

Welchau-1 Flow Testing;

• Testing of the already perforated Reifling formation (shallowest reservoir) will commence with fluid sampling and pressure measurement.
• It is anticipated the well will be stimulated with acid to mitigate damage and enhance productivity.

Shallow Gas and Oil Appraisal Drilling Program;

• Land has been acquired for three shallow gas prospects as well as the oil appraisal well.
• Drilling and environmental permits by end 2025, well site construction to commence in January 2026 and gas drilling in February 2026. Oil appraisal drilling scheduled for quarter three 2026.

ADX Executive Chairman, Mr Ian Tchacos, said "ADX looks forward to recommencing testing of the Welchau-1 well to determine the potential of the reservoirs intersected to date. Three of the four reservoir intervals with oil and gas indications and recovered hydrocarbons intersected by the Welchau-1 well remain untested. The potential of Welchau has not been conclusively assessed to date. The Welchau-1 well may also be deepened at a future time with the appropriate permits to assess further exploration potential below the current depth of the well - Welchau Deep prospect.

"ADX has assembled a multi well drilling program having secured drill sites for the four wells, has progressed environmental and drilling permitting as well as securing long lead items and services to commence drilling during the first quarter of 2026. The shallow gas drilling program including the HOCH, GOLD and SCHOE prospects together with the SGB oil appraisal well next to the Anshof field, provides an exceptional opportunity for organic growth. The low-risk nature of the program increases the likelihood that multiples of production growth can be achieved. Success with the initial shallow gas play program will enable additional follow up drilling across multiple shallow gas prospects which are being matured by the Company.

"The program can be funded by utilising cash reserves and farmout funding. ADX is in discussions with interested parties and expects to secure a farmout transaction by the end of 2025."
