FAIRBANKS- A local man has been named the new president and chief executive officer of International Tower Hill Mines . Tom Irwin has served as vice president of the company for two years, overseeing its Livengood gold project, 70 miles north of Fairbanks. Irwin's promotion comes amid significant changes at the British Columbia–based firm. The company is cutting about 30 percent of its staff, and its board of directors is being sliced from seven members to three. He starts his job on January first. Irwin says the moves are designed to conserve cash, advance discussions with other companies and continue environmental studies required for permitting.
