ITH Discovers New Sediment Hosted High-Grade Gold Mineralization at Livengood Project, Alaska Intercepts Include 8.8m of 9.95 g/t Gold and 8.5m of 9.64 g/t Gold

August 1, 2007

Vancouver, B.C........International Tower Hill Mines Ltd. ("ITH" or "the Company") - (TSXV: ITH, OTCBB: ITHMF, Frankfurt: IW9) is pleased to announce significant new drill results from it ongoing resource definition drill program at the Livengood Project, Alaska.  Believed to be the first of its kind discovered in Alaska, the new results confirm the presence of high-grade, 'sediment-hosted', disseminated gold mineralization.  This new style of mineralization overlies the mineralized lower grade volcanic units which have been the main focus of the exploration in the central target area of the property (currently measuring 1500 metres long by 500 meters wide). Geologically, the sediment-hosted mineralization displays strong similarities to world-class gold deposits in Nevada.

Drilling is currently underway to define the extent of this new zone of mineralization, which was first intercepted in Hole MK-07-15 and then subsequently in Hole MK-07-18, 85 meters to the east (Table I). In addition to the high-grade sediment-hosted mineralization, Hole MK-07-18 intersected a 78.6 meter interval of 1.09g/t gold in the lower volcanic zone, significantly expanding this part of the Livengood deposit.

Implications

The discovery of high-grade, sediment-hosted gold mineralization in Hole MK-07-18 is highly encouraging, as it opens a new chapter of exploration for the Livengood project.  While previous drilling in 2006 had encountered calcareous siltstones similar to those that host the high-grade mineralization in other parts of the property, until now these were not seen as significant potential targets. The new intersections show that, in the correct structural setting, these siltstones can become a significant host for mineralization.

The newly discovered sediment-hosted mineralization occurs in the same flat-lying stratigraphic interval in both Holes MK-07-15 and MK-07-18.  This new mineralization type is characterized by decalcification, chaotic fracturing, strong oxidation and outboard silicification.  The highest grade parts of these new zones are associated with strong decalcification and commonly contain stibnite.  These features are some of the key defining characteristics observed in many of the world-class gold deposits of Nevada.

Hole MK-07-17 was targeted on expanding the southern extent of the mineralized volcanic unit below the upper thrust plate rocks in the Lillian target area.  The 37 meter intercept of 0.82 g/t gold in this hole continues to demonstrate the very considerable upside potential of this target.  Due to the orientation of the overlying thrust fault the stratigraphic interval which hosts the sediment-hosted mineralization has been truncated and was not intersected in MK-07-17.  This information indicates the volcanic hosted zone, which has been intersected in every hole drilled to date in the Lillian target area, will extend considerably to the south below the thrust.

The 2007 Livengood drill plan calls for approximately 8,000 meters of core drilling as an initial assessment of the central target zone.  This exploration program is the Company's initial step in assessing the 2 by 3 kilometre gold in soil anomaly on its 44 square kilometre property package at Livengood.
