Appointment of Tom Obradovich to Board of Directors

The Company is also pleased to announce the appointment of Tom Obradovich to its Board of Directors, effective September 2, 2025.

Mr. Obradovich is a graduate of the Haileybury School of Mines in Mining Technology and Advanced Field Geophysics and brings over forty-two years of diverse expertise in mining exploration, development and financing. His professional achievements include co-founding Canadian Royalties Inc., which successfully discovered and developed the Raglan South Nickel Belt. Mr. Obradovich also spearheaded the acquisition of most of the Matachewan Gold Camp in Ontario and following a strategic reverse takeover of Young-Davidson Mines, successfully upgraded and doubled the resource. The Young-Davidson project was subsequently acquired by Northgate Minerals in 2005 and has since become one of Canada's largest underground gold mines, currently producing over 200,000 ounces of gold per year under the ownership of Alamos Gold Inc.

One of Mr. Obradovich's most notable achievements was his role as a founding member of Aurelian Resources Inc., which discovered the Fruta Del Norte gold deposit in Ecuador. Following its acquisition by Kinross, the project was brought into production by Lundin Gold, earning its place as one of the world's lowest-cost gold producers.

Michael Henrichsen, CEO of Gold X2, commented, "Goldshore Resources' rebranding to Gold X2 Mining marks a pivotal moment in our evolution, as we prepare to release an updated Mineral Resource Estimate (MRE) and Preliminary Economic Assessment (PEA), and advance the Moss Gold Project into its next phase of development. As we embark on this new chapter, we're sharpening our focus on holistic de-risking, driving value creation, and positioning Gold X2 for long-term success. We're also delighted to welcome Tom Obradovich to our board, whose 42 years of mining expertise, experience working on iconic gold mines, and vast industry network will undoubtedly move Gold X2 forward."

Corporate Update

• Economic Study and Advanced Technical Work: The Company is working closely with G Mining Services to publish a Preliminary Economic Assessment (PEA) in late Q4, which will feature an updated Mineral Resource Estimate (MRE) incorporating 21,329 meters of new drilling data and 15,972 meters of re-assayed historical drill core
• Environmental & Permitting Work: Our consultants are progressing environmental base line studies on schedule, including the initial sampling of aquatic species across thirty sites in the Wawiag and neighbouring catchments, the initial analyses to evaluate waste rock geochemistry, and stage 2 archaeological field studies with the assistance of local community members. Additionally, the Company has been expanding access to allow the drilling of the remaining nested water well pairs in the vicinity of the potential tailings management facility.
• Resource Expansion and Growth: With the aim of resource expansion the Company has commenced 29,000 meters of drilling in the "Moss Block", an area approximately 8 km x 6 km that is centred on the Moss Gold deposit containing 91% of the current Mineral Resource ounces of the project. Management believes that this ongoing drilling will ultimately help continue growing the project ounces and protect performance as the Company shifts focus from PEA to PFS.

In addition, the Company is pleased to have completed the repurchase of a 1% NSR from Wesdome Gold Mines, thereby reducing future project obligations and enhancing the Moss Gold Project's long-term economics by preserving future cash flow. Furthermore, Gold X2 Mining is actively working towards meeting the requirements for a potential listing on a major US exchange, targeting the second half of 2026 to satisfy requirements and list securities in the United States.
