Cameco is saying that the start of production at the Cigar Lake uranium mine could be delayed by a couple of months.
The company says ground freezing at the site has not advanced as quickly as expected in some localized areas of the mine.
Given that the McClean Lake mill has not yet started processing Cigar Lake ore, Cameco has decided to temporarily stop jet-boring at Cigar Lake to allow the ore body to freeze more thoroughly in these areas.
It says the additional freezing will allow more continuous production at the mine once the mill is operational.
As a result, Cameco says the production schedule could shift by a couple of months. It could mean that ore that was expected to be milled at the end of the year will shift into early 2015.
The company says it will know more at the end of the month when an assessment is complete.
