ITH Intersects 4.2 Metres of 22.3 g/t Gold on Major Extension of the Vein System on the Terra Project, Alaska
|November 16, 2006
Vancouver, B.C........International Tower Hill Mines Ltd. ("ITH" or the "Company") -- (TSX Venture: ITH, Frankfurt: IW9, OTCBB: ITHMF) is pleased to announce results from its drilling and surface exploration program on the Terra project. ITH has expanded the surface prospecting program at Terra to cover the full 8 kilometre strike length of the system and, as a result, has identified new vein systems which have returned a number of high-grade gold values. In addition, the Company conducted a limited drilling program on the extension of the "Ben Vein" (the focus of the 2005 drilling campaign) which returned high-grade intervals from both holes drilled on the 150 metre step out. The Ben Vein system has now been intersected in all eight holes drilled along the greater than 250 metres of strike length and 250 metres down dip and it remains completely open. Results from the six holes drilled in 2005 and the two holes drilled in 2006 indicate the Ben Vein system has remarkable continuity of grade and appears to be expanding in width to the northwest, as shown by the last hole which intersected 4.2 metres averaging 22.4 g/t gold (see Table 1 and Figure 2 below).

The Terra project is located approximately 200 kilometres west of Anchorage, Alaska within the Cretaceous porphyry belt of the Western Alaska Range (which hosts the Pebble and Whistler deposits). ITH is earning a 60% interest in the Terra project from AngloGold Ashanti (U.S.A.) Exploration Inc. ("AngloGold"). In order to earn its interest, ITH is required to incur US$3 million in expenditures on the project over 4 years, and it anticipates incurring approximately US$1 million in 2006. Upon ITH earning its 60% interest, AngloGold will have a one time opportunity to earn back 20% by incurring US$4 million in expenditures over two years, leaving ITH with a 40% interest.
During the surface mapping and sampling program in 2006, ITH collected 136 rock and rock chip channel samples from the Terra project, which ranged in values from <2 ppb to 130 g/t Au (average value for all 136 rock samples is 6.8 g/t Au and 33.7 g/t Ag). This work have now defined 4 main zones of veining in the core Terra target area, as well as a new zone of veining 4 kilometres to the south in the Ice Vein area (13 samples averaging 24.8 g/t gold and 170 g/t silver with a high chip sample of 0.5 m @ 72.3 g/t gold and 453 g/t silver) (See Figure 1 and Table 2). Each of these five vein zones has multiple high-grade veins that are intimately associated with the Terra Diorite. The grades in each are comparable to those found in the Ben Vein zone, which has averaged in the drilling, over a minimum true width of 1 metre, approximately 25 g/t gold (gold values ranging from 6 g/t to 136 g/t). Structural studies indicate that all of the veins have a common north-northwest to north-south trend with variable westerly dips. In addition, a new blind vein was discovered in the 2006 drilling (1.65 metres @ 13.9 g/t gold), which increases the tonnage potential of the system.

The Terra mineralization has been characterized as deep epithermal and could have significant extent down dip and along strike. The project has potential to develop a number of continuous high-grade veins forming a highly attractive mining target. Gold characterization work on the Ben Vein system indicates a very large percentage of the gold and silver can be recovered through gravity concentration.
The Company's proposed 2007 work program at Terra will include approximately 50 metre spaced drilling along 300 metres of strike length and 300 metres down dip on the Ben Vein system to evaluate the grade and continuity of this potentially large, high-grade deposit. In addition, ITH plans to test two of the other vein systems to asses their potential to develop similar systems. The proposed 2007 work program has an estimated budget of US$2 million.
Qualified Person and Quality Control/Quality Assurance

Pontius, President of 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 are 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.
