SASKATCHEWAN – Crews safely re-entered the main working level at of the Cigar Lake uranium mine development on Feb. 10, 2010. Test mining was halted in October 2006 when the workings flooded.
Prior to re-entry, the mine was fully dewatered and the main shaft refurbished including installation of the ladderway, replacement of electrical and mechanical components, and extension of the in-shaft pumping system. The workings at the 420 metre level, where the last inflow occurred, have been inspected and secured.
Safe access to the 480-metre level has been established and work to inspect, assess and secure the underground development has begun, according to 50% owner and operator Cameco Corp. of Saskatoon. This work will be followed by restoration of underground mine systems and infrastructure in preparation for resumed construction activities. Areva Resources Canada holds the other 50% of the joint venture.
Cameco expected to complete work to secure the Cigar Lake mine before October 2010. No word on how much remediation has cost or an expected start-up date for commercial production.
