Vancouver, B.C……..International Tower Hill Mines Ltd. (“ITH” or the “Company”) - (TSX: ITH, NYSE-MKT: THM, Frankfurt: IW9) is pleased to provide positive results from the metallurgical test work on its 100% owned Livengood Project located in Alaska.

Metallurgical studies have determined that the gold recovery for the four key rock types that comprise the majority of the Livengood Gold resource will range between 77 and 88 percent.  A substantial portion of the early production at Livengood is expected from these rock types.

The study program included tests to first determine the gravity recoverable gold, and then evaluated two alternative mill flow sheets for processing of the gravity tailing.  The tests showed a robust gravity recovery of between 43 and 55 percent.  The gravity recovery, total gravity/flotation/concentrate Carbon-in-Leach (CIL) recovery, and the total gravity/whole ore CIL recovery by major rock type are outlined below:

Table 1.  Gold Recovery by Rock Type as Determined by SGS Test work (%) 

Rock Type	Gravity	Gravity/flotation concentrate CIL	Gravity/whole ore CIL
Cambrian	49.0	81 (est.)	84.2
Upper Seds, Sunshine	44.1	76.1	87.7
Upper Seds, Core Zone	43.5	67.4	76.7
Volcanics, Core Zone	55.3	74.4	84.8

Note:  These four rock types comprised approximately 70% of the mineable resource described in the August 2011 PEA.  The Feasibility Study will update and define the percentage of each rock type contained in the mineable resource.

These results are based upon test work completed on a large number of representative samples contained in the 10,800 kg of mineralized rock that was delivered to SGS Canada Inc. in February, 2012.  This extensive program of optimization testing and analysis, overseen by Samuel Engineering, has defined the recovery for these rock types that will be used in the Feasibility Study.

Based on this successful test program and related engineering tradeoff studies, the Company has determined that a gravity circuit followed by a whole ore CIL circuit will be the mill flow sheet developed in the Feasibility Study.

Donald C. Ewigleben, CEO, stated: “I am very pleased with the results of these extensive metallurgical tests completed over the last eight months which have validated and defined the overall gold recoveries on this exceptional gold deposit.  This work has defined the milling flow sheet for the project as the Company continues to focus on other overall project optimization aspects that could further enhance its development.”

Additional metallurgical test work continues at SGS to confirm recovery on the Lower Seds, Core Zone rock type.  This rock type will be primarily encountered and processed later in the mine life.  This additional test work will be completed and incorporated into the Feasibility Study, which is on schedule for release by the first half of 2013.
