International Tower Hill Mines Announces Schedule

for Completion of Pre-Feasibility Study

Vancouver, British Columbia, July 15, 2020 – International Tower Hill Mines Ltd. (the “Company”) - (TSX:

ITH) (NYSE American: THM) today announced that it has finalized the key contracts for completion of the

previously announced Pre-Feasibility Study (PFS) on the Livengo od Gold Project and expects to release the

results of the PFS and the associated NI 43-101 Technical Report in October 2021.

The comprehensive study will inco rporate work that has been don e since the last NI 43-101 report was

completed to further de-risk and identify the optimal project c onfiguration. The Company has engaged BBA,

Inc. as its lead consultant and has retained Whittle Consulting , Resource Modeling, Inc., Resource

Development Associates, Easton Process Consulting, and NewFields Companies, LLC to provide specialized

technical support.

“BBA has been our lead consultant since 2015 and has extensive experience with similar large-scale gold

projects, such as Detour Lake and Canadian Malartic.” said Karl Hanneman, CEO. “We look forward to

working alongside BBA and our other consultants to provide an updated PFS during October of next year. The

work from this study will help the Company determine the approp riate next steps to continue to create

shareholder value.”

As set forth in the Company’s April 2017 NI 43-101 Technical Re port, the Livengood Gold Project has a

measured and indicated gold resource of 11.5 million ounces. Th e Company believes that the recent strength

in the price of gold arising from the unprecedented accommodative fiscal and monetary stimulus from central

banks and governments globally provides the necessary macroeconomic backdrop to support the advancement

of the large, highly-levered, and long-life gold asset at Livengood.
