ITH Doubles Gold Resource at Livengood Project, Alaska

International Tower Hill Mines Ltd. ("ITH" or "the Company") (TSX VENTURE: ITH)(NYSE-A: THM)(FRANKFURT: IW9) is pleased to announce the results of its independently prepared mid-year mineral resource estimate for the Money Knob deposit at its Livengood gold project near Fairbanks, Alaska. The independent study incorporates approximately half the drilling that has been completed on the property in 2008. The Company anticipates a further major expansion of the open-ended resource when the results from the outstanding drilling are returned and an 'end-of-program' resource estimate is completed in mid-first quarter 2009. In addition, the Company is very pleased to see such a large percentage of the estimated resources upgraded to the indicated category (approximately 45% indicated resources and 55% inferred resources), noting that the average grade of the previous 2007 inferred resource increased significantly in the 2008 indicated resource (a 17% increase in grade), see Table 1.

This new data confirms the Company's belief that the Livengood Deposit has an excellent possibility to become one of North America's largest new gold discoveries. The pre-eminent gold endowment of the system is strongly illustrated by a 95% increase in the overall gold ounces when calculated at a 0.30 g/t cutoff (Table 2) and a 160% increase in the overall gold ounces when calculated at a 0.7 g/t gold cutoff. This increase dramatically highlights the overall grade increase of the estimated resource in the deposit (Table 3).

Livengood Project Highlights

- Independent study notes that the Livengood Deposit has significant expansion potential beyond its current 1.86M ounce indicated and 2.17M ounce inferred gold resource estimate (at 0.5 g/t gold cutoff), with assay results still pending for many drill holes and the deposit remaining open in all directions.

- New deep and eastern step out drill holes to the Core Zone have intersected thick alteration zones, highlighting the potential for significant near-term expansions of the deposit.

- Preliminary metallurgical information shows favourable cyanide solubility for possible heap leaching with increasing recoveries at finer crush sizes offering milling potential of the higher grade areas.

- The project has a favourable logistical location and no major permitting hurdles have been identified to date.
