ITH Discovers Bulk Tonnage Gold System in Nevada
Intersects 51.8m @ 2g/t Gold on its North Bullfrog Project, Nevada

April 14, 2008

Vancouver, B.C........International Tower Hill Mines Ltd. ("ITH" or "the Company") - (TSXV: ITH, AMEX:
THM, Frankfurt: IW9) is pleased to announce initial results for the first 11 holes of its resource definition drill program at the North Bullfrog project, Nevada. Results to date from the Mayflower target are highly encouraging, with broad zones of gold mineralization cored by narrower zones of high grade gold being intersected, such as 51.8 meters of 2.0 g/t gold (including 9.1 meters of 7.2 g/t gold) and 38.1 meters of 1.4 g/t gold (including 15.2 meters of 2.9 g/t gold) (See Table 1).

This initial drill program is addressing 2 of 6 priority targets in the North Bullfrog District scale gold system, located 10 kilometres north of the historic Bullfrog mine that produced approximately 2.3 million ounces in the 1980-90's. The new ITH drill results, when linked with the very encouraging historic drill results (see ITH-NR 07-32), continue to support the Mayflower as a new bulk tonnage gold discovery in Nevada with significant expansion potential.

In addition, the Company has recently completed an initial 11 borehole test on the Air Track Hill target, located 3 kilometres northwest of the Mayflower. The boreholes have intersected broad zones of permissive alteration and gold assay results are expected imminently. The encouraging alteration and mineralization discovered to date in the North Bullfrog offers strong encouragement for the development of a series of deposits in this District scale gold system which, in total, could form a major new Nevada gold deposit.

Initial Mayflower Results

The total mineralized intervals above 0.25 g/t gold for all 11 holes have returned an average thickness of 33.3 metres with an average grade of 0.91 g/t gold, highlighting the project's bulk tonnage potential (See Table 2). These initial holes have confirmed the presence of a broad zone of silicification and adularia alteration around the main Mayflower fault zone which is intimately associated with the gold mineralization. Alteration appears to be best developed in specific horizons and is noticeably more intense in the north-western part of the target area. The mineralized intervals are highly oxidized to depth and representative samples have submitted for initial metallurgical testing.

Drilling has confirmed the continuity of the structure over a strike length of at least 900 metres and is providing insights into the structural controls on higher grade mineralization. Drilling currently underway will test several structural concepts as the system expands at depth (Figure 1). This drilling phase will conclude in mid April, at which point the Company will assess the resource potential of this new Nevada discovery. Results from this phase of exploration will form the foundation for a follow-up District wide resource development program in the late fall as the Company's Alaskan programs are advanced.

As a note, drill holes NB-08-08, NB-08-09 and NB-08-16 were drilled through old workings and had no or very poor recovery through the mineralized zone, and were therefore ineffective at evaluating it. Hole NB-08-13 was a stratigraphic hole which did not cross the main mineralized zone.

Property Summary

The North Bullfrog Project area is located near Beatty, Nevada and has excellent access and infrastructure. It is 7 kilometres north of the historic Bullfrog mine, which was operated by Barrick Gold Corporation until the mid 1990's (see NR07-05). The North Bullfrog project is held under option from Redstar Gold Corporation (TSXV: RGC), whereby ITH can earn up to a 70% interest in the project. To date, the Company has completed approximately half of the work commitment required to earn its initial 60% interest.

The Mayflower target is comprised of 11 patented mining claims and is focused along a northwest-trending, steeply-dipping, high-grade quartz-calcite vein system hosted in volcanic rocks. The broad, well-mineralized intercepts in both the historic and recent drilling are primarily developed within favourable volcanoclastic units along a well developed, broad structural zone forming a large bulk tonnage target.
