Livengood Deposit Significantly Expands High Grade Core Zones

September 4, 2008

MK-RC-0031 161.6 metres @ 1.02 g/t Au and 15.2 metres @ 2.0 g/t Au

Vancouver, B.C....International Tower Hill Mines Ltd. ("ITH" or the "Company") - (TSXV: ITH, AMEX: THM, Frankfurt: IW9) is pleased to announce the latest drill results from the ongoing 2008 resource expansion program at its bulk tonnage Livengood gold project in Alaska. The ongoing results continue to significantly expand the open ended, higher-grade Core Zone of the deposit, which has now been intersected for approximately 1000 metres along strike, across widths of 300-500 metres and is mineralized over an average thickness of approximately 100 metres. The Company has received results from 21 additional drill holes with another 32 holes completed but assays pending. To date the Company has completed a total of 75 holes of its planned 150 hole resource expansion drilling program (Figure 1). To date the 2008 drill pattern has tripled the size of the area previously drilled and used in the February 2008 resource statement which returned 87.8Mt containing 2 million ounces at an average grade of 0.71 g/t using a 0.5 g/t Au cutoff. The currently defined orebody at Livengood is a relatively flat lying tabular zone which outcrops at surface and appears amenable to low cost bulk mining. Notable intersections from the different parts of the Core Zone are:

Southern Extension 

  • MK-RC-0031: 161.6 m @ 1.02 g/t Au (including 3.05 m @ 7.07 g/t Au) and 15.2 m @ 2.0 g/t Au
  • MK-RC-0034: 39.6 m @ 1.94 g/t Au (including 4.57 m @ 8.33 g/t Au), 30.5 m @ 1.13 g/t and 12.2 m @ 1.29 g/t Au
  • MK-RC-0033: 38.1 m @ 1.33 g/t Au
 Western Extension
  • MK-RC-0024: 50.3 m @ 1.38 g/t Au (including 6.1 m @ 6.52 g/t Au)
Eastern Extension
  • MK-RC-0037: 29 m @ 1.32 g/t Au
Central
  • MK-DD-08-30: 55.89 m @ 1.05 g/t Au, 13.4m @ 2.31 g/t Au and 9.1 m @ 3.53 g/t Au
These holes along with early geochemical arsenic 'gold-pathfinder' results indicate the Core Zone is extensive and remains fully open along strike, to the east and at depth. Mineralization from the south end has extended into all units and is interpreted to indicate that the system is growing in strength and grade in this direction (Table 1). The favourable sedimentary and volcanic package as well as the overlying thrust appears to be flattening as the drilling follows the Core Zone to the south, bring the ore zone closer to the surface.

Drilling has tripled the size of the 2007 drill area, focusing on expanding higher grade Core Zone. The collars of holes with continuous intercepts of greater than 50 metres width and >1 g/t gold are highlighted.

The bulk of the 2008 drilling will be focused on expanding the higher grade Core Zone, which has consistently returned thicker and higher grade intercepts. The Company is planning to have the new drilling modeled in October of this year with a new NI 43-101 resource statement due in late October. This new resource statement should better characterize the size and grade of the newly discovered Core Zone and set the stage for further expansions as the other half of the 2008 drilling is completed this fall.

In addition to the encouraging results from the Core Zone two scout core holes were drilled 500 metres to the east in the phase II target area which returned encouraging intercepts including MK-08-27: 15.6m @ 1.06 g/t Au and MK-08-28: 14.5 m @ 0.95 g/t Au and 17.3 m @ 0.67 g/t Au. Each of these holes also encountered numerous other mineralized intersections which indicate that the Livengood gold deposit extends in this direction offering significant expansion potential.

The Company has submitted 23 additional metallurgical characterization samples to Hazen labs to further assess the leachability of the Livengood ore. These samples are an extension of the existing study which found gold to be occurring as native gold and electrum and extractable with cyanide leaching (see NR NR08-06).

The Company continues to operate two reverse circulation drills and one diamond drill on the property and anticipates completing its 2008 drilling program by November. The Company is currently planning a February start-up for the 2009 drilling program. The Company has adequate funds in its treasury to complete its currently planned 2009 drilling program for Livengood.
