ITH Discovers New High-grade Gold Mineralization on West Pogo Project, Alaska

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 1, 2008) - International Tower Hill Mines Ltd. ("ITH" or the "Company") (TSX VENTURE:ITH)(NYSE-A:THM)(FRANKFURT:IW9) is pleased to announce the discovery of high-grade gold mineralization at its West Pogo Project in Alaska. The Company's 2008 West Pogo exploration program has discovered a new area of high-grade gold mineralization to the east of earlier discoveries. Six of the 24 rock samples taken from this new zone returned greater than 1 g/t gold, ranging in grade from 1.2 to 118.5 g/t gold from sericitically altered granite and quartz vein material. This zone falls within an overall east-west trend of high-grade gold occurrences extending for some 25 kilometres within the Pogo Gold District (Figure 1).

Previous exploration at West Pogo focused on the area on the western side of the property where historical sampling had encountered weakly anomalous rocks and soils. The 2008 program focused its effort on the eastern side of the property within a recently burned area which enhanced rock exposures. A train of mineralized granite float was encountered 150 metres northeast of the 2003 AngloGold Ashanti (U.S.A.) Exploration Inc. ("AngloGold") drill site with visible gold found in several pieces of float. Additional mineralized rocks and anomalous soils were found over an area extending over 700 metres to the east of the visible gold discovery. The mineralization consists of vuggy quartz veins and breccias in granite with strong sericitic and local tourmaline alteration. The mineralization has modest arsenic values and low bismuth values (Table 1).

(i) A total of 24 rock samples were taken from the new zone, ranging in
grade from nil to 118.5 g/t gold and averaging 5.54 g/t gold. Of
these samples, 54% exceeded 0.5 g/t gold and 25% exceeded 1 g/t gold.

The controls on mineralization are not well understood at the moment, however, the distribution of mineralized rocks and soils suggest the high-grade gold mineralization is related to an east-northeast structural zone along the margin of a granitic intrusive. This newly discovered high-grade mineralization is exciting in that it lies along a generalized east-west trend of district-scale gold occurrences that extend both east and west of the Pogo Mine. The Company plans to follow up on these highly encouraging results as time and resources become available.

West Pogo Project Summary

The West Pogo Project consists of a 20 square kilometre block of State of Alaska mining claims owned 100% by the Company and located 5 kilometres west of the Pogo Gold Mine. The bedrock geology consists of Paleozoic metamorphic rocks which have been intruded by younger, probably Cretaceous, granites. Gold mineralization was first discovered in the area in 1998 with the property being acquired by AngloGold in 2001. In 2003 a single hole was drilled by AngloGold which encountered wide zones of sericitic alteration and multiple zones of low-grade gold mineralization.

Qualified Person and Quality Control/Quality Assurance

Jeffrey A. Pontius (CPG 11044), a qualified person as defined by National Instrument 43-101, has supervised the preparation of the scientific and technical information that forms the basis for this news release. Mr. Pontius is the President and CEO of ITH.

The 2008 work program at West Pogo was designed and supervised by Dr. Russell Myers, Vice President of Exploration, Talon Gold (US) LLC (a wholly owned subsidiary of ITH responsible for carrying out the Company's exploration programs), who is responsible for all aspects of the work, including the quality control/quality assurance program. On-site personnel at the project photograph all sample shipments which are then sealed and shipped to ALS Chemex in Fairbanks, Alaska for preparation and on to Vancouver, B.C. for assay. ALS Chemex's quality system complies with the requirements for the International Standards ISO 9001:2000 and ISO 17025:1999. Analytical accuracy and precision are monitored by the analysis of reagent blanks, reference material and replicate samples. Quality control is further assured by the use of international and in-house standards. Finally, representative blind duplicate samples are forwarded to ALS Chemex and an ISO compliant third party laboratory for additional quality control.
