In late November of early December 2005, ICG acquired Anker West Virginia Mining Company Inc who had been the official mine operator of Sago Mine. The official Sago Mine operator became Wolf Run Mining Company in late 2005. Wolf Run Mining Company was a subsidiary of Hunter Ridge Mining Company, which in turn was a subsidiary of the parent company ICG according to Vice President Sam Kitts in his testimony before the Mine Safety and Health Administration (MSHA) hearing on March 23, 2006. Kitts identified Ben Hatfield as his supervisor during the period of transition from Anker to ICG. ICG was in the process of acquiring Anker in November 2005.
