Faro mine cleanup slowed by complications: Yukon minister

Cleanup of one of Canada's most notorious contaminatedsites continues, with no end in sight.

Yukon's mines minister told the legislature on Monday that the government is trying to close the Faro mine site, but there have been frequent setbacks.

"Some of the complications that have emerged in the last year includesome water quality challenges in the north fork of Rose Creek," Minister Scott Kent said.

"That may translate into the construction of a new dam and diversion system worth a substantial amount of dollars in the next three to five years."

The Faro mine produced lead, silver and zinc from about 1970 until 1998. The federal government took over the site when the owner went bankrupt. In 2009, the federal and Yukongovernments agreed on a plan to deal with the estimated64,000 hectares of contaminated soil and groundwater.

Part of the agreementrequires Yukon to come up with a closure plan for the Faro site, with the help of federal money.

"What does Yukon have to show for the millions of dollars spent on the Faro remediation project?" asked NDP mining critic Jim Tredger.

"There is still no finalized closure plan for Faro. And it is unclear if the mine site has even been stabilized to an appropriate level."

The Faro mine has become one of Canada's most expensivecleanup projects.Contaminantsat the site include petroleum hydrocarbons, metal, metalloid and organometallics.
