Sudbury, Ontario-Officials with Vale S.A. aren’t revealing any details about the police investigation into ammonium nitrate being discovered in the gas tank of a contractor’s bulldozer at the company’s Sudbury mine in September. Reports are that Vale contacted police about what was termed an act of mischief after the bulldozer couldn’t be operated. “When they started looking at why the bulldozer stopped working, they found something had been poured into the gas line in the bulldozer,” Sudbury Sgt. Rick Waugh told the local press. Vale spokeswoman Angie Robson responded to Green Markets that “I will not be able to comment on this so as not to jeopardize the ongoing criminal investigation. All I can say is that we are taking this incident very seriously and are fully cooperating with the police in their investigation.” Nearly a year-long strike of more than 3,000 steelworkers was ended at Vale’s Sudbury operations in July.
