VANCOUVER, BRITISH COLUMBIA--(Marketwire - Nov. 7, 2011) - International Tower Hill Mines Ltd. ("ITH" or the "Company") (TSX:ITH)(NYSE Amex:THM)(FRANKFURT:IW9) announces results from 92 drill holes completed since June 2011 at its Livengood project located near Fairbanks, Alaska. New results from close-spaced infill drilling in the Core and Sunshine Zones confirm resource estimates based on wider spaced-drilling. This, and other infill drilling, also encountered locally higher grade mineralization. Highlights include hole MK-RC-531 which intercepted 17.27 g/t gold over 4.6 metres in the Sunshine Zone, hole MK-RC-522 which intercepted 8.0 g/t gold over 4.6 metres in the Core Zone and hole MK-RC-537 which intercepted 8.7 g/t gold over 3.1 metres in the Tower Zone. These findings enable the Company to define the higher grade zones in the Livengood gold deposit which may be targeted during the initial phase of mining.
The results also include drill holes focused on project development activities related to mine design and environmental characterization as well as step-out resource growth drill holes. Results so far are supporting the identification of potential infrastructure locations, although new areas of significant gold mineralization have been identified. The Company has also completed an initial district-wide geophysical survey which has confirmed a strong response to alteration directly associated with the current deposit. This finding will greatly aid in further target definition along a 10-kilometre-long strike system previously identified on the 145 km2 Livengood land package. Analysis of geophysical data along trend is in progress with results expected in the following weeks to define the next phase of district exploration drill targets.
Site Development and District-Wide Exploration
The majority of step-out drilling conducted this summer was directed at project development activities related to mine design and environmental characterization. Results to date have been encouraging for development; however, condemnation hole MK-10-97, which was drilled over two kilometres southeast of the Money Knob deposit, did intercept significant mineralization of 4.82 g/t gold over 1.57 metres and favorable host rocks. In addition, holes MK-11-119 (1.68 m at 5.72 g/t Au), MK-11-120 (1.22 m at 5.00 g/t Au), and MK-123 (9.77 m at 0.83 g/t Au) intersected mineralized dikes over a broad area north and east of the deposit indicating further mineralization potential (see Figure 1 - http://media3.marketwire.com/docs/1107ITH_Fig1.pdf). Assay results for four additional holes in this area are pending. If findings warrant further exploration, the Company has already identified an alternative mill location.
Exploration drilling is also underway on the Moose and Lucky target areas located approximately 5 kilometres to the northeast of the current Money Knob deposit, which were previously identified through surface soil geochemistry. Results will become available in the upcoming months.
Geophysical Program
A district-wide 3D IP/Resistivity geophysical survey has been completed as part of an integrated exploration program targeting the discovery of further deposits to the east and northeast of the current Livengood deposit (lines shown in Figure 1 - http://media3.marketwire.com/docs/1107ITH_Fig1.pdf). Following the completion of data acquisition, analysis of the lines over the Money Knob Deposit has produced a strong and coherent anomaly over the main mineralized zones. Within the Livengood Deposit, alteration associated with the gold mineralization creates resistivity highs (see Figure 2 - http://media3.marketwire.com/docs/1107ITH_Fig2.pdf). This association of high resistivity and mineralization will be an invaluable tool in defining other district exploration targets within the 187-line-kilometre grid.
Confirmation Drilling
Infill drilling to date on the deposit has sucessfully achieved four objectives, all of which increase the confidence level of the resource size and grade:
- Evaluation of the shape and continuity of mineralization away from main feeder zones: Infill Reverse Circulation (RC) drilling to 15-metre spacing drilling was conducted on intersecting north-south and east-west sections in two locations marginal to the Core and Sunshine zones (see Figure 3 - http://media3.marketwire.com/docs/1107ITH_Fig3.pdf). Results to date indicate similar grades and continuity to those previously estimated.
- Confirmation of the continuity of mineralization in the Tower and Core zones: Infill drilling to 50-metre spacing was conducted in the Tower and Core zones and results to date continue to confirm continuity and grade in both zones.
- Confirmation of data collected through RC drilling: Additional evaluation holes were drilled to provide more RC and core drilling comparisons. To date, these have been favorable and support the data collected from RC drilling throughout the deposit.
- Evaluation of the correlation of grade between RC and diamond core drilling: Close-spaced (37.5-metre) alternating core and RC drilling of a 150 x 150 x 150 m block (Area 50) in the heart of the Sunshine Zone in two directions (north and northeast) was conducted to evaluate the correlation of grade between the two drilling techniques as well as the effect of drilling direction on the estimated grade of the block. Results to date compare favourably with prior wide-spaced drilling and suggest a higher grade, northwest trend within the mineralization.

Livengood Project Highlights
ITH controls 100% of its approximately 145 square kilometre Livengood land package, which is made up of fee land leased from the Alaska Mental Health Trust, a number of smaller private mineral leases and 115 Alaska state mining claims. The project has a favourable logistical location, being situated 110 road kilometres north of Fairbanks, Alaska, along the paved, all-weather Elliott Highway, the Trans-Alaska Pipeline Corridor, and the proposed Alaska natural gas pipeline route. The terminus of the Alaska State power grid lies approximately 80 kilometres to the south.
Ongoing metallurgical studies are focused on the optimization of the milling and flotation unit operations contemplated in the updated August 2011 PEA.
The geometry of the currently defined shallowly dipping, outcropping deposit enables development of a large scale, low stripping ratio surface mine capable of generating significant production economies of scale. The surface gold geochemical anomaly at Livengood covers an area 10 kilometres long by 2 kilometres wide, of which approximately one quarter has been explored by drilling to date. Surface exploration is ongoing as new targets are being developed to the east and west of the known deposit.
Geological Overview
The Livengood Deposit is hosted in a thrust-interleaved sequence of Proterozoic to Paleozoic sedimentary and volcanic rocks. Mineralization is related to a 90 million year old (Fort Knox age) dike swarm that cuts through the thrust stack. Primary ore controls are a combination of favorable lithologies and crosscutting structural zones. In areas distal to the main structural zones, the selective development of disseminated mineralization in favourable host rocks is the main ore control. Within the primary structural corridors, all lithologies can be pervasively altered and mineralized. Devonian volcanic rocks and Cretaceous dikes represent the most favourable host lithologies and are pervasively altered and mineralized throughout the deposit. Two dominant structural controls are present: 1) the major shallow south-dipping faults which host dikes and mineralization which are related to dilatant movement on structures of the original fold-thrust architecture during post-thrusting relaxation, and 2) steep NW trending linear zones which focus the higher-grade mineralization which cuts across all lithologic boundaries. The net result is broad flat-lying zones of stratabound mineralization around more vertically continuous, higher grade core zones with a resulting lower strip ratio for the overall deposit and higher grade areas that could be amenable for starter pit production.
The surface gold geochemical anomaly at Livengood covers an area 6 kilometres long by 2 kilometres wide of which approximately half has been explored by drilling to date. Surface exploration is ongoing as new targets are being developed to the northeast and west of the known deposit.

The resource work program at Livengood was designed and is supervised by Chris Puchner, Chief Geologist (CPG 07048), of the Company, who is responsible for all aspects of the work, including the quality control/quality assurance program. On-site personnel at the project photograph the core from each individual borehole prior to preparing the split core. Duplicate reverse circulation drill samples are collected with one split sent for analysis. Representative chips are retained for geological logging. On-site personnel at the project log and track all samples prior to sealing and shipping. All sample shipments are sealed and shipped to ALS Chemex in Fairbanks, Alaska for preparation and then on to ALS Chemex in Reno, Nevada or 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.
