"The court ruling allows ADX to resume testing operations at Welchau-1. The ruling also places ADX in a strong position to obtain the necessary permits for further exploration drilling including the deepening of the Welchau-1 well to access the Welchau Deep Prospect"

Key points:

• ADX holds a 75% economic interest in the Welchau discovery and other emerging prospects in the Welchau Investment Area located in ADX' ADX-AT-II licence in Upper Austria.
• ADX drilled the Welchau-1 well during the first quarter of 2024 in accordance with drilling permits issued in November 2023 by the Ministry of Finance of the State of Austria and environmental clearances granted by the local Upper Austrian State Government authority responsible for the Nature Conservation (Environmental Clearances).
• In early 2025 four registered Austrian environmental non-governmental organisations (ENGOs) objected to the Environmental Clearances. A court ruling repealed a previous law allowing operations to be undertaken during the review process for an objection to an Environmental Clearance. As a result of this ruling, ADX suspended the Welchau-1 testing operations until the State Administrative Court of Upper Austria opined on the objections to the Environmental Clearances made by the ENGOs (refer ASX Release dated 14 January 2025).
• The Upper Austrian State Administrative Court has now ruled that the Environmental Clearances were granted in accordance with the regulations and that ADX has conducted drilling and testing activities to date conscientiously, safely, based on applicable laws and in compliance with all the conditions of the permits (Ruling).
• Based on the Ruling, ADX may resume drilling and testing activities at the Welchau-1 location during the winter months from the 1st of October to the 31st of March.
• The Ruling in favour of the continuation of Welchau operations is based on the strong public interest in Austria for finding and exploiting new domestic natural gas deposits.
• Three of the four reservoir intervals with oil and gas indications intersected by the Welchau-1 well remain untested, and their potential has not been conclusively assessed.
• The immediate forward plan for Welchau-1 is to conduct fluid sampling of the Reifling formation which was perforated prior to suspension of testing operations.

ADX Executive Chairman, Mr Ian Tchacos, said, "The Board of ADX welcomes the decision by the Upper Austrian State Administrative Court. The decision is not only important for further testing and exploration operations at Welchau, it is a very positive indication of the ongoing support for gas exploration due to the strong public interest for securing clean domestic natural gas reserves in Austria."
