Joe Cullen, CEO of Metalsource Mining, commented:

"This is a strategic acquisition we've been working toward for some time. As drilling, geophysics and geological interpretation have continued to improve our understanding of the Silver Hill system, it became increasingly important to secure these highly prospective properties while the opportunity was available. We're grateful to the families who have owned this land for generations and appreciate the trust they've placed in our team. Every successful drill hole has strengthened our confidence in the broader district and helped define where we believe the next phase of exploration should be focused. These newly acquired properties provide access to compelling exploration targets that we look forward to advancing in the near term as we continue expanding the known mineralized footprint at Silver Hill.
