Barry's valuable experience, in successfully building and operating large-scale mines throughout the Americas, is an important addition to the U.S. GoldMining team as we advance studies which we believe could unlock opportunities to develop a robust potential future mining opportunity. Having recently announced a State of Alaska led transformative access initiative that would directly connect the Whistler Project with existing transportation and energy infrastructure within the greater Anchorage region of Southcentral Alaska and combined with the launch of our 2025 exploration campaign that will explore multiple targets across our mineral district-scale Whistler Project land package, we are excited about the near-term and long-term opportunities to advance development of the Whistler Project."
