ITH Reports Initial Drilling Results at West Tanana Project, Central Alaska

Multiple mineralized zones intercepted, including 4.3 metres at 2.5 g/t gold and 9.5 metres at 1.1 g/t gold

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 18, 2007) - International Tower Hill Mines Ltd. ("ITH" or "the Company") - (TSX VENTURE:ITH) (AMEX:THM) (FRANKFURT:IW9) is pleased to announce the initial drilling results from its West Tanana Project in central Alaska. Highlights include a 10 centimetre quartz vein with visible gold in quartz within a 0.3 metre interval assaying 15.6 g/t gold and a broader breccia zone returning 2.5 g/t gold over 4.3 metres.

The initial phase of diamond drilling encountered both high-grade quartz veins and broad zones of potentially stratabound mineralization. The results successfully confirm the presence of significant lode gold mineralization beneath the original large soil anomaly and the presence of high-grade quartz veins (Table 1). Work is ongoing to define the key structural and stratigraphic controls on the mineralized zone to target follow-up drill testing in the future.


The West Tanana property is held by ITH by via a lease option agreement with Doyon Limited (see NR06-05 for terms). The initial drill testing at West Tanana has defined a shallow easterly dipping zone of broad gold mineralization. This zone, seen in drillhole WT-07-02, is approximately 30 metres wide and was also intersected in the very tops of two drillholes collared to the southeast. Difficult drilling conditions within major fault zones resulted in poor recoveries in a number of the holes, all but one being lost prior to testing the proposed target zones. The mineralized zones appear related to a series of stacked low angle shear zones. High angle quartz vein/breccia zones encountered in drillhole WT-07-08 may have acted as feeders to the low angle shear zones. This possible feeder zone, which may have also been the source for the placer gold deposit immediately above and downstream from it, is the Company's current focus on the project.
