Mr. Ferguson is a highly accomplished executive who brings more than 35 years of international mining experience across mine development, project execution, operations, business transformation and executive leadership. Most recently, he served as general manager of the Carlin mining complex for Nevada Gold Mines, where he was accountable for five underground mines, three open pits and five processing facilities producing approximately 1.4 million ounces of gold annually.

Frederick H. Earnest, president and chief executive officer of Vista Gold, stated: "We are very pleased to welcome Gavin to Vista Gold. Gavin's wide-ranging experience leading some of the world's largest gold operations, together with his project development and turnaround experience, adds exceptional technical, operational and project execution capability to Vista Gold's team. Gavin's appointment underscores our commitment to building a strong Australia-based leadership team to advance Mt. Todd. We are confident that he will play a vital leadership role in developing the project and creating long-term value for our shareholders."

Gavin Ferguson commented: "I am honoured to join Vista Gold and lead the Australian project execution team at such an important stage in the advancement of Mt. Todd.

"The 2025 feasibility study has established a compelling development proposition. The combination of a substantial gold reserve, long mine life, reduced initial capital requirement and strong projected economics provides a strong foundation from which to advance the project.

"The opportunity now is to execute. I am committed to working with Vista's board and management teams to take the Mt. Todd project from its current project stage through detailed engineering, development and first gold. I also look forward to building strong relationships with the Northern Territory government, traditional owners, local communities, contractors and other stakeholders."
