The company that's building an Upper Peninsula nickel and copper mine says it has contained and cleaned up a chemical leak at a water treatment plant on the Marquette County site.
According to Kennecott Eagle Minerals Co., less than 100 gallons of the chemical spilled early Saturday inside a storage area.
Kennecott says no one was hurt and no risk was posed to the environment.
The company says a faulty valve caused a container to leak the chemical into a containment area in a section of the plant designed to store chemicals used in the treatment process.
The chemical was contained within the sealed area, and cleanup of the leak was completed later Saturday.
Company spokeswoman Deb Muchmore says mineral extraction at the Eagle Mine is to begin in 2014.
