ITH Discovers Bulk Tonnage Porphyry Related Gold System at its Blackshell Project, Alaska

December 7, 2006
Vancouver, B.C..... International Tower Hill Mines Ltd. ("ITH" or the "Company") -- (TSX Venture: ITH, OTCBB: ITHMF, Frankfurt: IW9) is pleased to announce the results of the 2006 soil and rock sampling program on its, Blackshell Project, Alaska. The results confirm the presence of vein-style gold mineralization hosted within a porphyritic phase of a multiphase intrusive complex. In addition, significant gold mineralized veins have been encountered over an area of roughly 2 square kilometres. This mineralization exhibits a bismuth-arsenic association similar to that found at the Pogo gold deposit. These findings indicate that the Blackshell system has the potential to develop into a large, bulk tonnage deposit similar to the Fort Knox deposit.

Project Background

The Blackshell Property consists of 35 Alaska state mining claims (approximately 2,265 hectares) located in the Tintina Gold belt, 97 kilometres southeast of Fairbanks, Alaska and held 100% by ITH. The property is situated approximately 30 kilometres from an all weather paved road. The mineralization at Blackshell was discovered during an aggressive large regional stream sediment survey conducted by AngloGold Ashanti Exploration (U.S.A.) Inc. (AngloGold) in 2005. The program identified a number of late intrusions that are highly anomalous in bismuth and arsenic, elements that are intimately associated with mineralization at other producing gold mines in the belt, such as Pogo and Fort Knox. The granite that hosts mineralization is one of several younger granites that intrude a basement of Paleozoic sediments and metasediments and is believed to be of a similar age as the Fort Knox intrusions.

Results

The gold mineralization seen to date is hosted almost entirely within a porphyritic biotite-granite intrusion with several distinct textural phases. Gold bearing quartz veins have been found over an area of 2 square kilometres. Soil sampling and geological mapping have defined a core area of anomalous gold and sericitic alteration associated with a quartz-feldspar porphyry. Several styles of mineralization are present, including gold, molybdenum, and tungsten bearing veins and gold, copper, and tungsten mineralization associated with intense sulphidation in surrounding hornfels wall rock.

Two distinct styles of gold mineralization are present, one associated with higher temperature veins and one associated with silicification and lower temperature quartz (Table 1, sample 801639). There is a very strong correlation between gold and bismuth in the higher temperature veins (Table 1), which is typical at both the Fort Knox and Pogo deposits. The association of the gold mineralization and the late stage quartz-feldspar porphyry is a key factor in focusing the mineral system. ITH believes that the Blackshell Prospect has good exploration potential for a major bulk mineable gold deposit.



Qualified Person and Quality Control/Quality Assurance

EurGeol Dr. Mark D. Cruise, 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. Dr. Cruise is the Vice President-Exploration of Cardero Resource Corp. and is a shareholder of ITH. Cardero presently holds a 13.3% equity position in ITH.

The work program at the Blackshell project was designed and is supervised by Dr. Russell Myers, Vice President of Exploration for Talon Gold (US) LLC (a wholly owned subsidiary of ITH responsible for carrying out the exploration programs on ITH's Alaskan properties), who is responsible for all aspects of the work, including the quality control/quality assurance program. On-site personnel at the project rigorously collect and track samples which is then sealed and shipped to ALS Chemex 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.

International Tower Hill Mines Ltd. is a resource exploration company focused in Alaska that controls a number of exploration projects representing a spectrum of early stage to advanced gold discoveries. ITH is committed to building share holder value through new discoveries while maintaining a majority interest in its holdings, thereby giving its shareholders the maximum value for their investment.
