The Canadian government will not ask the Export Development Corporation to withdraw its US$117-million insurance for a Tanzanian gold mine operated by Barrick Gold in light of a video released yesterday that alleges local miners were killed during an eviction at the site...A national coalition made the requests after releasing footage from a police videotape, photographs of corpses, family testimony and eyewitness accounts, alleging that mass killings took place in August, 1996, as part of an operation to remove thousands of local miners from a site owned by Kahama Mining Corporation, a subsidiary of Sutton Resources of Vancouver. Barrick Gold acquired Sutton's assets in March, 1999. As part of its due diligence, the company probed the three-year-old allegations and found they were unfounded, said Patrick Garver, executive vice-president and general counsel.
