TSX: ITH | NYSE American: THM

International Tower Hill Mines Ltd. (TSX: ITH; NYSE American: THM)

is an advanced exploration stage company focused on the development of its 100% interest in the Livengood Gold Project located 70 miles northwest of Fairbanks, Alaska.

The Company announced the results of the Pre-Feasibility Study (the "PFS") for its Livengood Gold Project located near Fairbanks, Alaska on November 4, 2021. The PFS details a project that would process 65,000 tons per day and produce 6.4 million ounces of gold over 21 years from a gold resource estimated at 13.6 million ounces at 0.60 g/tonne. The PFS utilized a third-party review by Whittle Consulting and BBA Inc. to integrate new interpretations based on an expanded geological database, improved geological modelling, new resource estimation methodology, an optimized mine plan and production schedule, additional detailed metallurgical work at various gold grades and grind sizes, changes in the target grind for the mill, new engineering estimates, and updated cost inputs, all of which significantly de- risk the Project. The PFS has estimated the capital costs of the Project ("CAPEX") at US$1.93 billion, the total cost per ton milled ("OPEX") at US$13.12, the all-in sustaining costs ("AISC") at US$1,171 per ounce, and an after-tax NPV (5%) of US$400 million at $1,800/oz, US$975 million at US$2,000/oz, and US$2.3 billion at $US2,500/oz.
