Announcement PDF ASX Release 27 May 2025 EXTENSIVE AIRBORNE MAGNETIC/RADIOMETRIC SURVEYS COMPLETED OVER NT URANIUM PROJECTS Highlights  7,300 line kilometres of airborne magnetics/radiometrics have been flown over the Douglas River and Elkedra Uranium Projects.  This completes airborne survey coverage across all of Greenvale’s extensive Northern Territory uranium-focused land package.  Detailed geophysical interpretations are expected within two months.  Pending results will help develop and refine targets for field-based mapping and sampling programs and future drilling. Greenvale Energy Limited ASX: GRV (“Greenvale” or “the Company”) is pleased to announce the successful completion of airborne magnetics/radiometrics (mag/rad) surveys over its Elkedra and Douglas River Uranium Projects in the Northern Territory, Australia. Comprehensive Airborne Geophysics Survey Completed The airborne geophysics survey, covering a total of 7,300 line kilometres, was flown by Magspec Airborne Surveys using a Cessna 210 aircraft, specially modified for geophysical surveys. The surveys covered approximately half of both EL33670 (Douglas River) and EL33756 (Elkedra). The last survey lines were flown on 18th May. Preliminary assessment of the radiometric data will be undertaken by ASIS International, with Arrow Geosciences undertaking a detailed interpretation of magnetics overlain by radiometrics. The detailed geophysical interpretations are expected within the next two months. The geophysical survey data and interpretation will complement similar work completed over the Henbury and Jindare Projects earlier in the year, where multiple elevated uranium anomalies were identified 1. Greenvale CEO Alex Cheeseman said: “Completing this important foundational exploration work is a key step for Greenvale to identify follow-up targets across our extensive uranium-focused land package in the Northern Territory. 1 Refer to Compliance Statement on Page 4 Interactive Investor Hub - Engage directly with Greenvale through our Investor hub, you can ask questions, review comments and get direct access to the Company – follow the link greenvaleenergy.com.au/announcements Greenvale Energy Limited ABN 54000743555 W: greenvaleenergy.com Registered Office: Suite 5-Level 12, 10 Market St, Brisbane 4000 E: admin@greenvaleenergy.com.au Mail: GPO Box 1968, Brisbane 4001 Page | 1 Greenvale Energy Limited ASX Release The results will allow us to refine targeting opportunities and plan follow-up field work. Incrementally building our knowledge base will allow us to design focused and cost-effective follow-up groundwork programs, helping to streamline the exploration process. With investor sentiment in the uranium sector rebounding strongly, we are eager to move forward with these exciting projects.” Douglas River Project (EL33670) The Douglas Project covers an area of approximately 465sqkm and is located approximately 200km south of Darwin, in the Daly Basin on the south-western side of the Pine Creek Mineral Field. The project area has been historically explored for a number of minerals including uranium, gold, tin, base metals and diamonds with extensive anomalism defined from surface sampling. The Pine Creek Region is one of the world’s largest and richest uranium provinces, containing the Alligator River (Ranger and Jabiluka) deposits as well as the Rum Jungle and South Alligator Valley (Coronation Hill and El Sherana) deposits. Over the period 12th May to 18th May, an airborne survey totalling 3,775 metres was flown at a height of 40m and line spacing of 100m over the northern half of EL33670. Results are currently being reviewed and interpreted and are expected in the next two months. The Douglas Project Tenement area and areas flown in the recent airborne geophysics campaign are shown in Figure 1. Figure 1. Completed Douglas River Airborne Survey area Page | 2 Greenvale Energy Limited ASX Release Elkedra Project (EL33756) The Elkedra Project occupies an area of 566sqkm in the Barkly region of the NT, approximately 295km from Alice Springs. The project area contains Cambrian Arthur Creek Formation siltstones and Andagera Formation quartz sandstones, which overlie early Proterozoic Hatches Creek Group rocks composed of sandstones, siltstones, and volcanic units. These older rocks were intruded by the Elkedra granite (~1660 Ma), surrounded by a ~100m metamorphic aureole believed to be the source of anomalous uranium and thorium identified in historical geophysical surveys. Over the period 5th May to 11th May, an airborne survey totalling 3,525 metres was flown at a height of 40m and line spacing of 100m over the northern half of EL33756. Results are currently being reviewed and interpreted and are expected in the next two months. The Elkedra Project Tenement area and areas flown in the recent airborne geophysics campaign are shown in Figure 2. Figure 2. Completed Elkedra Airborne Survey area Future Works Following receipt of the modelled data, Greenvale intends to plan a follow-up field program, consisting of hand/held scintillometer ground geophysical surveying of airborne anomalies, mapping and geochemical surface sampling (soils and rock-chips). Greenvale intends to complete this work during the 2025 NT field campaign season/dry season.
