ITH Reports Initial Drilling Results from its North Bullfrog Project, Nevada


Drilling intersects 0.4 metres @ 17.6 g/t Au and 1.2 metres @ 3.7 g/t Au

VANCOUVER, BRITISH COLUMBIA--Sep 5, 2007 -- International Tower Hill Mines Ltd. ("ITH" or the "Company") (CDNX:ITH.V - News)(AMEX:THM - News)(Frankfurt:IW9.F - News) is pleased to announce the initial results from its phase one drilling program at its North Bullfrog Joint Venture (earning up to a 70% position from Redstar Gold Corp (CDNX:RGC.V - News). This initial phase drilling program intersected a number of broad lower grade zones of gold mineralization in the Sierra Blanca target area (including 7.6 metres @ 1.1 g/t Au) and high-grade mineralization in the Pioneer area (including 0.4 metres @ 17.6 g/t Au and 1.2 metres @ 3.7 g/t Au). The results have confirmed the presence of a large widely distributed gold system on the property and have set the stage for further drilling of a number of untested priority targets (see Table 1). The Company anticipates its phase II drilling program for the North Bullfrog project will begin early in the first quarter of 2008 as field activities slow down on its Alaskan projects.

Interpretation

At Sierra Blanca, holes NB0701 and NB0702 confirmed the presence of widespread low-grade mineralization encountered in historic drilling. NB0701 intersected numerous low-grade intervals, with 28% of the 247 metre hole mineralized at greater than or equal to 250 ppb Au. NB0702 also intersected low-grade mineralization, with a high of 2.060 g/t over 3 metres (0.060 opt over 9.8 feet). Previous drilling in the area of the two holes intersected thick low-grade intervals, including 0.343 g/t over a combined 40 metres (0.010 opt over 130 feet), 0.480 g/t over 35 metres (0.014 opt over 115 feet) and 0.425 g/t over a combined 26 metres (0.012 opt over 85 feet). The drilling tested only a small portion of the extensive low-grade mineralization at Sierra Blanca and did not evaluate areas with relatively higher-grade gold mineralization (greater than 1 g/t) encountered at surface and in shallow previous drilling. The potential for higher-grade structurally-focused mineralization also remains poorly tested at this stage, and the nearby Yellowjacket vein system target was not tested by the phase I program.

The shallow mineralization intersected in the Pioneer target area in NB0704 occurs along the margins of a strongly-altered dike, an important geologic control which will assist in on-going exploration. Hole NB0703 attempted to cross the west-dipping mineralized zone about 120m down dip and encountered anomalous gold values but failed to intersect the high grade shoot that was the original target. The Pioneer mine area has all of the earmarks of a large gold mineralizing system with the potential for more high-grade vein zones such as those intersected in NB0704.
