</div>Survey vessel M/V Byr returns safely to Iceland having covered more area with water depth data (bathymetry) than originally planned High-resolution seabed data already used to safely anchor support vessel Argus within 500 meters of the western outcropping mineralized zone at Skaergaard Data advancing toward official navigational charting and future shipping infrastructure planning for the Project's next development phase Initial HQ drill core supporting the metallurgical bulk sample successfully completed, with the program shifting to NQ-size core drilling from a newly established, fully operational core shack SKAERGAARD, Greenland, Aug. 17, 2026 <a href="https://www.globenewswire.com" target="_blank">(GLOBE NEWSWIRE)</a> -- via IBN – Greenland Mines Ltd ("Greenland Mines" or the "Company") (Nasdaq: GRML) is pleased to announce the successful completion of its 2026 bathymetric survey campaign at the Skaergaard Project in southeast Greenland, carried out by Icelandic Lagenes ehf using the expedition, research and survey vessel M/V Byr. The vessel has returned safely to Iceland having covered more survey area than originally planned, with the acquired data verified and confirmed to meet the high-resolution technical specifications required under the survey contract. M/V Byr, from Icelandic Lagenes ehf, was operated under the command of Sigurdur Jonsson, who has navigated the fjords of East Greenland for the past 25 years, and covered navigation route surveys and full multibeam coverage across Mikis Fjord, J.C. Jacobsen Fjord, Skaergaard Bugt and Uttendal Sund. Onboard the survey acquisition was overlooked by Survey Chief and Survey Engineer Lauri Aakko. The value of this new dataset has already been demonstrated in practice: High-resolution bathymetric data was used to safely guide the Company's support and operations vessel Argus to a new anchorage in Uttendal Sund, just 500 meters from the main initial operational area for the 2026 field season, located in the western part of the outcropping gold, palladium and platinum mineralized zone at Skaergaard. "This is precisely the kind of foundational work that turns a promising deposit into a developable project," said Dr. Bo Moller Stensgaard, president of Greenland Mines Ltd. "For the first time, we now have high-quality seabed data across the fjords surrounding Skaergaard, acquired to international survey standards and already put to direct operational use this season. “This survey will help enable the Danish Geodata Agency to produce new, official navigational charts for the Skaergaard fjord system. In parallel, we will use the data to commission a dedicated navigational safety study for the Company, and it will underpin the infrastructure planning required for future large-scale shipping operations at Skaergaard, covering both the construction and, ultimately, the production phases of the project. This is a major stepping stone toward the next phase of Skaergaard's development. "At the same time, our drill campaign continues to build momentum. All HQ-diameter drill core supporting our planned metallurgical bulk sample has now been completed successfully by our contractor Nordisk Fundering A/S, and the program has shifted into NQ-size core drilling, supported by a newly constructed and fully operational core shack facility on site." Marine Survey: Scope, Results and Strategic Value <ul type="disc"><li style="margin-top:0in; margin-bottom:8pt;">Survey scope exceeded: The campaign, conducted using multibeam bathymetric system aboard M/V Byr, covered more survey area than originally planned under the charter, providing broader data coverage across Skaergaard's approach fjords than initially scoped.</li><li style="margin-top:0in; margin-bottom:8pt;">Data quality confirmed: Acquired bathymetric data has been reviewed and confirmed to meet the high-resolution technical specifications required under the survey contract, providing the Company with a reliable, high-confidence dataset.</li><li style="margin-top:0in; margin-bottom:8pt;">Immediate operational value: Data was used to identify and safely execute a new anchorage for support vessel Argus in Uttendal Sund, within 500 meters of the western outcropping mineralized zone that is the focus of the 2026 field season's initial drilling and bulk sampling activity.</li><li style="margin-top:0in; margin-bottom:8pt;">Supporting official navigational charts: Survey results are now undergoing further review and validation and are expected to support and inform the official production of new navigational charts for the Skaergaard fjord system by the Danish Geodata Agency (“Geodatastryrelsen” – GST). The Company will also commission a dedicated navigational safety study based on the survey findings.</li><li style="margin-top:0in; margin-bottom:8pt;">Foundation for future shipping infrastructure: This is the first time comprehensive seabed mapping data has been acquired across the fjords surrounding Skaergaard, providing a foundation to support planning for the large-scale marine shipping operations that will be required for both future construction and, ultimately, production activities at the Project.</li></ul> Drill Program Update: Metallurgical Core Complete, Program Shifts to NQ In parallel with the marine survey campaign, the Company's 2026 drill program has reached an important milestone, with all HQ-diameter drill core required to support the planned multiton metallurgical bulk sample now successfully recovered by the contractor Nordisk Fundering A/S. Having completed this phase, the drill program has transitioned to NQ-size core drilling, the standard core diameter used for the resource definition and geotechnical drilling that will continue through the remainder of the season. A newly raised core shack facility, providing dedicated space for core logging, sampling and storage, has been completed and is now fully operational on site. A Season Delivering on Multiple Fronts Together, the successful completion of the marine survey campaign and the advancement of the drill program illustrate the breadth of the Company's 2026 field season at Skaergaard, which spans resource definition drilling, metallurgical bulk sampling, environmental baseline studies, and the marine and infrastructure data required to support the Project's advancement toward an Initial Assessment and its next phase of development. About the Skaergaard Project Skaergaard is one of the world's largest undeveloped palladium, gold and platinum deposits, hosted in the Triple Group of the Skaergaard layered mafic igneous intrusion in southeast Greenland, approximately 400 km west of Iceland. The deposit benefits from deep fjord access and proximity to the existing Sødalen airstrip. Greenland Mines, through its subsidiary Major Precious Greenland A/S, holds an 80% interest in and option to acquire the remaining 20% of the three Mineral Exploration Licenses covering the Project and adjacent areas. Skaergaard's location on Greenland's east coast is central to the Company's long-term vision for a North Atlantic Critical Metals Corridor, anchored by upstream production at Skaergaard and potential downstream processing and logistics infrastructure in Iceland. In support of this vision, Greenland Mines holds a First Right of Refusal on the Helguvik industrial complex on Iceland's Reykjanes Peninsula, a brownfield site with existing industrial infrastructure, deep-water port access and low-cost renewable grid power, located approximately 400 km by sea from Skaergaard. About Greenland Mines Ltd Greenland Mines Ltd is a Nasdaq-listed company with two operating divisions: (1) Mining, focused on the exploration and development of the Skaergaard Project in southeast Greenland and, subject to closing of the previously announced transaction, the Sarfartoq neodymium-praseodymium (Nd-Pr) rare earths project in southwest Greenland; and (2) Biotech, including Klotho's KLTO‑202 primary indication for ALS. The Company’s strategy is centered on building a multi-asset platform with exposure to rare earth magnet materials, precious metals, and select midstream processing opportunities, while advancing its broader North Atlantic Critical Metals Corridor vision linking Greenland resources with allied downstream jurisdictions and industrial infrastructure.
