ITH Intersects New Zone of Mineralization at its North Bullfrog Project, Nevada

Highlights include: 25.9 metres of 1.02 g/t gold & 9.2 metres of 1.2 g/t gold

VANCOUVER, BRITISH COLUMBIA--(Marketwire - April 29, 2008) - International Tower Hill Mines Ltd. ("ITH" or the "Company") (TSX VENTURE:ITH)(AMEX:THM)(FRANKFURT:IW9) is pleased to announce the results of initial drilling at Air Track Hill target in the north-western portion of the North Bullfrog Project. Eleven holes were completed at Air Track Hill to follow up on historical broad near-surface zones of gold mineralization (Table 1). New drilling clearly confirms the bulk tonnage and significant expansion potential of this large well mineralized area. Consequently, the Company has acquired an additional 52 claims (approximately 400 ha) around both the Air Track Hill and Mayflower discoveries (project area now totals 18 km2). ITH is currently earning a 70% position in the North Bullfrog District from Redstar Gold Corp. (TSX VENTURE:RGC).

The eleven holes, totalling 2,469 metres, were drilled at Air Track Hill which is located 3 kilometres north of the Mayflower target, results from which included 51.8 metres of 2 g/t gold (see News Release dated April 14, 2008). The results confirm key ore controls for the greater Air Track Hill - Sierra Blanca target zone covering some two square kilometres in area and extending under post mineral cover. The higher grade mineralization appears to be related to lithologic contacts and possible structures related to the margins of a postulated intrusive dome complex including intersections in holes NB-08-21 with 25.9 metres of 1.02 g/t gold and NB-08-26 with 9.2 metres of 1.20 g/t gold (Figure 1).

The mineralization outlined from this current program suggests that multiple stages of gold mineralization and alteration have occurred and preferentially mineralized rhyolite tuff units. In addition to the higher grade intervals numerous zones of low-grade mineralization have been interested throughout the Air Track Hill - Sierra Blanca area which is believed to be a major center of gold mineralization in the Northern District (Figure 2). This large gold system appears associated spatially with a very significant gold/adularia alteration system further supported by results such as 7.6 metres of 1.11 g/t gold from the Company's Sierra Blanca's drilling last year. This bulk multi-million ounce target concept will be the focus of the Company's future work in this area of the District. The Company anticipates having the results completed for the remaining 13 drilled in the Mayflower deposit by late May after which it intends to complete a resource model for use in defining the economic potential of the deposit and planning follow-up expansion drilling to be conducted late in 2008 or early 2009 during an anticipated winter slow down on the Livengood resource expansion drilling project.
