ITH Acquires Key Land Position on Its Coffee Dome Project, Alaska and Dramatically Expands Its Gold Soil Anomaly

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - March 13, 2007) - International Tower Hill Mines Ltd. ("ITH" or the "Company") (TSX VENTURE:ITH)(OTCBB:ITHMF)(FRANKFURT:IW9) is pleased to announce that it has entered in to an Exploration Agreement with Option to Lease with the University of Alaska regarding a key University of Alaska property adjacent to the Company's Coffee Dome project. This new ground expands the Coffee Dome Project by approximately 1,300 hectares. The target concept at Coffee Dome is for an intrusion related high-grade vein deposit similar to the Pogo Mine.

In 2006, the Company carried out an expanded soil survey on the University of Alaska ground, which generated a strong 700 by 200 metre gold and trace element anomaly. The results also indicate a possible extension of this anomaly a kilometre to the north. To date, the Company has also collected 111 rock samples on the University ground, which have returned values ranging from 2 ppb to 96.6 g/t gold. The top 15% of these samples (17) average 31.2 g/t gold, 3% arsenic, 109 ppm bismuth and 16.8 ppm tellurium (Figure 1).

Project Background

The Coffee Dome project was originally acquired by AngloGold Ashanti (U.S.A.) Exploration Inc. in 2005 by a combination of staking new ground and leasing a 1,800 hectare block of Alaska State claims. The project was subsequently acquired by the Company when it purchased AngloGold's Alaskan property portfolio in August, 2006. This road accessible project is located in the Yukon-Tanana geological terrane which, in this area, is composed of metamorphic rocks of the Fairbanks Schist formation. The regional structural fabric is dominated by northeast trending strike slip faults, whose subsidiary structures appear to be controlling the mineralization on the project. Despite the project's close proximity to a major multimillion ounce mine it has received little exploration prior to AngloGold's acquisition of the project. The first soil survey ever conducted on the project was that conducted by AngloGold in 2005. To date a total of 819 soil samples and 111 rock samples have been collected on the property, which have defined three significant gold in soil anomalies, including the most recent zone identified on the University land. The project has not yet been drilled.

Exploration Agreement

On March 7, 2007 Talon Gold Alaska, Inc. (the wholly owned Alaska subsidiary of ITH) ("Talon"), signed a two stage Exploration Agreement with Option to Lease with the University of Alaska. The Exploration Agreement has an effective date of January 1, 2007 and covers approximately 1,300 hectares of land lying to the north of the existing Coffee Dome project. ITH has guaranteed the obligations of Talon under the Exploration Agreement. The key terms of the Exploration Agreement (and any resulting mining lease) are as follows:

Exploration Agreement: In order to maintain the option to lease in good standing, Talon is required to pay the University USD 117,500 over five years (USD 15,000 first year) and incur exploration expenditures totalling USD 400,000 over five years (USD 25,000 commitment for the first year). If Talon does not terminate the option prior to January 1 in any option year, the specified minimum expenditures for that year become a commitment of Talon. Talon is also responsible for all taxes and assessments on the lands subject to the option.

Mining Lease: At any time during the option period, Talon has the right to enter into a mining lease over some or all of the lands subject to the option. The mining lease will have an initial term of 15 years and for so long thereafter as commercial production continues and requires escalating advance royalty payments of USD 30,000 in year 1 to USD 150,000 in year 9 and beyond. Advance royalty payments are credited against 50% of production royalties. Talon is also required to incur escalating minimum mandatory exploration expenditures of USD 125,000 in year 1 to USD 350,000 in year 5 and beyond and to deliver a feasibility study within 10 years of the commencement of the lease. Upon the commencement of commercial production, Talon will pay a sliding scale net smelter return royalty of from 3% (USD 300 and below gold) up to 5% (USD 500 and up gold). Talon will also pay a sliding scale net smelter return royalty of from 0.5% (USD 450 and below gold) to 1% (USD 450 and above gold) on any federal or state claims staked by Talon or its affiliates within a 2 mile area of interest surrounding the University land (not including Talon's existing leased claims).

Target Summary

The target concept for the Coffee Dome project is for a high-grade vein deposit hosted within the metamorphic rock package of schist and quartzite. The quartz veins encountered to date are commonly banded with scorodite and arsenopyrite having textures suggestive of crack-seal and open space filling. Due to the extensive cover in the area the majority of the veins are scattered rubble crop occurrences ranging in width from 10-30 centimetres that are highly anomalous in gold, arsenic, bismuth, and tellurium. Due to the limited exposure, trenching will be required to assess vein density, width and orientation; although it appears from work to date that the veins are occurring in swarms along a generalized northeast trend.

The new large, very strong soil anomaly on the University ground is highly encouraging as it is significantly larger than the previous anomaly to the south (which has returned the high-grade vein values in rock sampling). This new anomaly, as well as a new area developing to the north, may be suggestive of an en echelon series of vein deposits which, in total, could potentially represent a very large gold system covering several square kilometres. ITH is planning an aggressive trenching and drilling program for the Coffee Dome project in 2007 to follow-up on the outstanding results received to date.

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 work program at Coffee Dome was designed and is 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. All geochemical samples are secured 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.
