The news wires are alive with reports of a billion dollar estimate for remediating the Giant Mine in Yellowknife, Northwest Territories. Here is an extract from one report:
Documents obtained by northern environmentalists show the government expects the cost of cleaning up the Giant Mine just outside Yellowknife to be nearly a billion dollars – perhaps the largest single environmental cleanup in Canada and paid for entirely by taxpayers. Initial estimates for safely dealing with the huge site, which includes a toxic smorgasbord of buildings, tailings ponds and a quarter-million tonnes of arsenic stored underground, were about $488 million. A federal progress report on the project says costs have increased as more has become known about the scale of the problem.
“The increase in estimated costs occurred as a result of the normal progression through the preliminary phases of the remediation project (… increased site information and detail obtained over time),” the report says. Rising labour and equipment costs are also part of the problem. So is the current state of the mine, which is so bad that emergency measures need to be taken this summer before large amounts of arsenic start escaping from collapsing buildings. The official price tag of $903 million could get higher yet.
