Livengood, which contains 13.6 million ounces in gold resources, is among one of the largest undeveloped gold projects in the United States.

Marcelo Kim, chairman of International Tower Hill, stated: "We are extremely pleased to welcome David and Shane to the leadership team and board of directors of International Tower Hill. David brings extensive experience raising mine development capital, structuring project financing and leading public mining companies, while Shane brings deep permitting, mine development and operational experience in Alaska. Together, they form a highly complementary leadership team with the experience required to advance Livengood through feasibility, permitting, financing and construction to unlock its full value."

The company also announced that Karl Hanneman will transition from his role as chief executive officer and remain with the company as strategic adviser and director to support the leadership transition and continuing advancement of the Livengood gold project.

Mr. Kim continued: "We would also like to express our sincere gratitude to Karl Hanneman for his outstanding leadership, dedication and stewardship of the company. Karl has been instrumental in strengthening the company's technical foundation, maintaining strong stakeholder relationships and positioning the company for the future. We are very pleased that Karl will continue to work closely with the company as strategic adviser and director to ensure a seamless transition, and provide access to his deep knowledge of the project as we advance Livengood into its next phase."

Mr. Wiens brings more than two decades of mining finance, capital markets and strategic leadership experience across the global mining sector. Mr. Wiens most recently served as chief financial officer of Asante Gold Corp., where he led approximately $1-billion of innovative financing transactions to support its growth into a mid-tier gold producer while transforming its shareholder register.

Prior to his corporate roles, he was a mining investment banker at several financial institutions, including Deutsche Bank.

In connection with his appointment, Mr. Wiens has agreed to subscribe for $200,000 (U.S.) of common shares of the company. The investment reflects Mr. Wiens's confidence in the company's long-term prospects and further aligns his interests with those of shareholders. The private placement is expected to close following his commencement as chief executive officer, subject to customary regulatory approvals and the execution of definitive subscription documentation.

Mr. Parrow is a highly experienced mining executive with nearly 30 years of operational, engineering, and project development experience across open pit and underground mining operations. Most recently, Mr. Parrow served as vice-president and general manager of Kinross Alaska, overseeing the Fort Knox and Manh Choh operations.

Prior to Kinross, Mr. Parrow held senior operating and project leadership roles at Argonaut Gold, Sibanye-Stillwater, Barrick and Newmont.

Mr. Wiens commented: "I am excited to join International Tower Hill at such an important stage in the evolution of the company. Livengood is a world-class gold project with significant scale and strategic importance. I look forward to working closely with Shane, the board and the broader team to advance the project responsibly and create long-term value."

Mr. Parrow added: "Livengood represents one of the most compelling development-stage gold projects in North America. I am excited to apply my operational and project development experience in Alaska to help advance the project through the next stages of engineering, permitting and development."
