International Tower Hill Begins Drilling at Coffee Dome Project, Alaska

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Sept. 2, 2009) - International Tower Hill Mines Ltd. ("ITH" or the "Company") (TSX VENTURE:ITH)(NYSE Amex:THM)(FRANKFURT:IW9) is pleased to announce that drilling has begun to test the "UAF Target" at its Coffee Dome Project, Alaska. The initial phase of the program will include 1,000 metres of diamond drilling, which the Company anticipates will be completed near the end of October. This will be the first drilling carried out at Coffee Dome, a major new, Alaskan, road accessible, gold discovery that lies just 17 kilometres from the Fort Knox Mine. The drilling will be testing one of three surface gold targets developed by Company geologists from the initial soil sampling and trenching program. The drilling will be targeting high-grade vein style mineralization similar to that discovered in surface trenches immediately to the south (Table 1) that have returned grades up to 168 g/t gold (see NR07-31).

UAF Target

The UAF target is focused along a projected northwest trending structural zone which appears to be steeply dipping to the south (Figure 1). The target is a coincident resistivity and high-grade gold in soil anomaly. The main UAF target as currently defined is 500 metres by 250 metres. The initial drilling will test the width and depth of the mineralized zone and establish the nature of the structural control on the mineralization.

Project Background

The Coffee Dome Prospect is characterized by very high-grade quartz-gold-arsenopyrite veins hosted in metamorphic rocks. Mineralization is characterized by high values of gold, bismuth and arsenic and is believed to represent high temperature mineralization similar to that found in the Fort Knox and Pogo Gold Mines. Trenching has shown that vein hosted mineralization is associated with a variety of fault structures in the schist, ranging from low-angle oblique slip structures to high-angle NE-trending faults. The geochemical anomaly at the UAF zone is parallel to and coincides with a major break in airborne resistivity, which suggests that the mineralization coincides with a fault that juxtaposes two different rock types. It is this structure that will be the target of the first two holes in this drilling campaign.

ITH controls 100% of the Coffee Dome land package, consisting of 41 square kilometres primarily made up of State of Alaska Mining Claims owned or leased by ITH and fee land leased from the University of Alaska. Coffee Dome is located in the Fairbanks Gold Mining District, 17 kilometres northeast of the Fort Knox Gold Mine. The project is accessible via a network of Alaska State maintained forest roads that connect to the State highway system near the Fort Knox Mine. The mineralization at Coffee Dome was discovered after fires in 2004 exposed the surface for the first time, revealing several boulder trains of quartz vein material hosting high-grade gold mineralization. Work to date has defined several gold targets stretching over a strike length of some 4 kilometres, outlining a large precious metal rich hydrothermal system.

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 and has approved the disclosure herein. Mr. Pontius is not independent of ITH, as he is the President and CEO and holds common shares and incentive stock options.

The work program at Coffee Dome was designed and is supervised by Dr. Russell Myers, Vice President, Exploration, and Chris Puchner, Chief Geologist (CPG 07048), of the Company, who are responsible for all aspects of the work, including the quality control/quality assurance program. On-site personnel at the project log and photograph the core from each individual borehole prior to preparing the split core. On-site personnel at the project log and track all samples prior to sealing and shipping. All sample shipments are sealed and shipped to Alaska Assay Laboratories in Fairbanks, Alaska for preparation and a preliminary gold assay. Pulps are then transferred to ALS Chemex in Fairbanks who forwards them to other ALS Chemex facilities for final gold and multi-element analysis. 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.
