International Tower Hill Mines To Commence District-Wide Exploration Program at the Livengood Gold Project, Alaska

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 04/18/12 -- International Tower Hill Mines Ltd. ("ITH" or the "Company") (TSX: ITH)(NYSE Amex: THM)(FRANKFURT: IW9) announces that, on May 1, 2012, it will be commencing two major field drill programs consisting of district-wide exploration and condemnation drilling at the Company's 100% controlled Livengood Gold Project near Fairbanks, Alaska. Results from the drill programs are expected throughout the summer and fall of 2012.

The Company plans to drill 3,000 metres in 10 core holes as part of its initial district-wide exploration program focused on making new discoveries in the Company's 145 km2 land package. Prior drilling, mapping and surface geochemical sampling conducted in 2010 had identified an area northeast of the Money Knob deposit where faults, dikes and anomalous gold coincide, indicating an area of potentially significant mineralization. An initial three holes are planned to target the area to assess the extent of the mineralization (see Figure 1). Subsequent exploration drill sites are contingent on the results of the initial holes.

In addition, a 40-hole, 6,000-metre program of condemnation drilling will be carried out to either sterilize or establish the presence of significant mineralization in the area surrounding the Money Knob deposit and extending northeast towards existing mineralized exploration drill holes. The purpose of the condemnation drilling program is to determine appropriate areas for infrastructure development.

"With our Money Knob deposit sitting at over 16.5 million ounces in the Measured and Indicated, and 4.1 million ounces in the Inferred, resource categories, it is important for us to look in new areas of our land package to see if we can find additional gold deposits," stated Jim Komadina, Chief Executive Officer. "In addition, as the Livengood project progresses toward permitting and development, it is crucial to begin engineering data acquisition so that regulatory and community engagement can begin. The condemnation drill program is designed to enable Tower Hill Mines, Inc. to be ready for these important discussions in the first quarter of 2013."

In separate news, the Company confirmed today that the report of the Company's independent public accounting firm on its audited consolidated financial statements for the seven month period ended December 31, 2011 and for the year ended May 31, 2011, as filed with certain Canadian regulatory authorities and with the United States Securities and Exchange Commission in the Company's annual report on Form 40-F, on March 26, 2012, contained an "emphasis of matter" paragraph in relation to a going concern explanatory note. The note did not modify the report of the independent auditor, but instead draws attention to Note 1 of the Company's audited consolidated financial statements which describe certain material uncertainties related to the ability of the Company to continue as a going concern. Under rules of the NYSE Amex the inclusion of such a paragraph is required to be announced. As disclosed in Note 1 to the Company's audited consolidated financial statements, the Company's current working capital is considered sufficient to fund its operations and exploration program for the current fiscal year.
