International Tower Hill Expands Higher Grade SW  

VANCOUVER, BC - International Tower Hill Mines Ltd. reported assay results for 16 additional holes of the 2010 Winter drilling campaign at the Livengood gold project, including the first holes this year from the high-grade SW Zone. Seven of the nine new holes reported from the SW Zone returned cumulative grade thicknesses exceeding 100 gram metres and demonstrate this area as a new large emerging high-grade zone along the currently defined western limit of the deposit. Higher grade intercepts in the SW area include 71.6 metres at 1.11 g/t gold, 24.4 metres of 2.81 g/t, 59.4 metres at 0.96 g/t and 19.8 metres at 4.43 g/t gold, thus confirming and expanding the Zone as defined in 2009.

Many of the new higher grade SW holes intersected several +1 g/t gold intervals within the top 150 metres from surface, thereby outlining potential starter pit mineralization for the proposed mill. The combination of higher grades, significant areal extent, and open-ended mineralization indicate high potential for significant resource addition to the Money Knob gold deposit. Assays are pending for an additional 10 holes in the SW Zone, all of which will be included in the ongoing Preliminary Economic Assessment (PEA) that is examining the potential of a combined mill-heap leach recovery circuit. Significantly, three of the four new holes in the Sunshine Zone returned cumulative grade thicknesses greater than 100 gram metres, including hole MK-RC-0328 with 21.3 metres at 2.9 g/t gold. In addition, thick mineralization was encountered from near surface to +150 metres in depth from the two northern most holes (MK-RC-340 and 331) in the currently defined Sunshine Zone, thereby indicating significant potential for expansion. Assays for the final three North Sunshine holes in the winter campaign are pending. Results from two core holes - one in the Northwest Zone (MK-10-49) and one in the Core Zone (MK-10-48) - returned comparable values to those in the surrounding holes. Intervals from these core holes will be used in the Company's ongoing metallurgical and environmental studies (hole MK-10-49 was completed as a ground water monitoring well).
