In addition to this application ADX previously announced two (2) exploration permit applications on the 19th of August 2026, named d 368 C.R-.AU and d 369 C.R-.AU (refer to figure 1). The three permit applications are proximal to ADX’ existing C.R 150.AU Exploration Permit (346 km2). ADX holds a 100% interest in the C.R 150.AU Permit in the Sicily Channel, offshore Italy. A recent independent review by RISC Advisory Pty Ltd (RISC), refer to ASX Release dated 6 July 2026, recognised that the Miocene aged, Terravecchia Formation is a valid biogenic gas play in the Sicily Channel based on the analysis of the regional geology, offset wells with gas shows and analogous discoveries at the nearby onshore Lippone-Mazara Terravecchia gas field and the offshore gas developments at the Pliocene Argo-Cassiopea fields. RISC noted that in offset wells surrounding the ADX Permit, the sandstones which are developed within the dominantly shaley Terravecchia Formation frequently displayed elevated mud gas shows during the drilling of historic wells. Figure 1: Shows the d 370 C.R-.AU permit application as well as the previously announced d 368 C.R.-AU and d 369-C.R.-AU application areas adjacent to ADX’ C.R 150.AU Permit with in the Terravecchia gas play in the Sicily Channel (shaded in orange).
