ITH Continues to Significantly Expand Sediment Hosted Mineralization at Livengood Gold Deposit, Alaska

September 27, 2007
Vancouver, B.C........International Tower Hill Mines Ltd. ("ITH" or the "Company") (TSXV: ITH, AMEX: THM, Frankfurt: IW9) is pleased to announce latest drill hole results from its ongoing Livengood exploration and phase I definition drill program. The results from the latest three holes have significantly expanded both the sediment and volcanic hosted gold zones to the south and east (Table 1). In total all three holes have returned composite mineralized intervals above cut-off in excess of 125 metres which are some of the broadest zones intersected to date. These three holes intersected a number of sediment hosted intervals significantly expanding this emerging zone of mineralization. In addition a new zone of gold mineralization was intersected in the overlying upper plate rocks which returned a 6.3 metre interval of 2.43 g/t Au.

The expansion of the Livengood gold system into all the rock units in the central 4 km2 target area is encouraging as the mineralized system is now totally unconstrained with potential to expand significantly beyond the central target area.

Ongoing drilling (assay pending) in broad step out holes has intersected the favourable volcanic host which is mineralized. This step out drilling has now extended the mineralized zone to at least 1 kilometre along strike and ½ km of width (Figure 1). Drilling is expected to continue until at least mid-October and will focus on larger step outs to the south, west and east in an attempt to constrain this large mineralized system. Initial 43-101 resource estimates for Livengood will be calculated this winter and a 50,000 metre resource definition and expansion drilling program is being planned for 2008.

Implications

The three holes reported here represent progressive step outs on the initial Lillian Creek discovery and have now added continuity to both the sediment and volcanic hosted mineralization. It is important to note that all of the drill holes completed to date have intersected numerous zones of gold mineralization over broad widths, a strong indicator the deposit has significant expansion potential (Table 2). This new data has provided important geological information to guide future drilling for the expansion of the deposit. In addition the near-surface, highly oxidized, sediment hosted portion of the deposit is developing into an attractive near-term production opportunity that is being closely evaluated by the Company.

At the request of the Company, internationally renowned geological consultant Dr. Richard Sillitoe recently visited a number of the Company's properties in Alaska, including the Livengood property. The results of his visit are summarized in a geological report dated August 26, 2007 and entitled "Comments on the Livengood, Chisna and Terra Prospects, Alaska". The report is not a "Technical Report", as defined in N.I. 43-101, but the complete report may be viewed at www.ithmines.com.

With respect to the Livengood property, Dr. Sillitoe had the following comments and strongly recommends additional work in order to fully ascertain the property's potential: "Livengood is interpreted as a strata-bound gold prospect located distally with respect to a parent pluton at depth. Numerous, narrow monzonite porphyry dikes connect the inferred pluton with the site of mineralization. Permeable stratigraphic horizons, most notably amygdaloidal andesite flows, moderately welded ash-flow tuff, and overlying decalcified calc-siltstone, host most of the gold, with minor amounts present in the feeder dikes. An exceptionally thick volcanic section, interpreted as the fill of a paleovalley, contains much of the gold. Tonnage extensions to the coherent zone of gold mineralization already defined are most likely to be found along the strike projections of the paleovalley, but could also occupy sites of enhanced permeability elsewhere. The concept of low-order geochemical values representing leakage from concealed gold zones at depth is valid and merits a scout-drilling program."
