ITH Further Defines Mineralization at South Estelle

October 18, 2007
Values up to 238 g/t Gold from 700 metre long Shoeshine vein system

Vancouver, B.C........International Tower Hill Mines Ltd. ("ITH" or the "Company") - (TSXV: ITH, AMEX: THM, Frankfurt: IW9) is pleased to announce results from its preliminary exploration program on the South Estelle Project, Alaska held under option from Hidefield Gold plc. Fieldwork at South Estelle has identified outcropping high-grade gold mineralization at the Shoeshine, Train and Portage Prospects (Figure 1). The Shoeshine vein system has a currently defined strike length in excess of 700 metres containing numerous high-grade chip samples, including one characterization sample which returned 238 g/t gold and a 0.3 metre wide channel sample with 126 g/t gold (Table 1). The Company believes that the Shoeshine and Train vein systems represent attractive high-grade gold vein systems with potential to host significant high-grade gold mineralization similar to those being defined on the Terra project, located 40 kilometres to the west.

Background

The target at the South Estelle Project is the high-grade quartz-sulphide veins, which are generally hosted in the 65Ma Mount Estelle monzonite batholith. The property borders the large Kennecott Exploration Whistler project currently being explored for copper-gold deposits by Geoinfomatics. In 2006, fieldwork at South Estelle by the London-listed Hidefield Gold plc and Mines Trust Company of Anchorage identified a number of mineralized areas and the subsequent 2007 ITH program focussed on understanding the structural controls on vein development and, in addition, expanding these exciting new discoveries. Results show that, with the exception of the Train Prospect, all the vein systems have very similar orientations, trending north-northwest with steep dips to either the northeast or southwest. These are the same as the vein orientations found in the Company's high-grade Terra Project 40 kilometres to the west. Furthermore, the high-grade veins at Terra are developed in an intrusive of similar age to that at South Estelle. At Terra, these high-grade gold veins are best developed near the margins of the intrusive and can have exceptional continuity (see NR 07-24 and the Company's website at www.ithmines.com for details).

Preliminary Exploration Program Results

The Shoeshine and Train Prospects have produced the most interesting results to date (Fig.1, Table 2). The high-grade gold veins discovered to date at the Shoeshine prospect are narrow, but have a consistent north-northwest trend over an extensive strike length and could be an indication of a large high-grade system at depth. In at least one example, a fault hosts high-grade gold mineralization. Experience gained from work on the Company's Terra project suggests that these fault-hosted veins can develop significant lateral and vertical continuity. The Company is currently planning the 2008 exploration program for the Shoeshine and Train targets.
