Cameco announced that dewatering and shaft remediation at the Cigar Lake project are proceeding as expected. The remediation effort is currently focused on refurbishment of the main shaft and is about two-thirds complete. This work involves installation of the ladderway in the shaft, replacement of mechanical and electrical components, and extension of the in-shaft pumping system.
Cameco Corporation announced today that dewatering of the underground development of the Cigar Lake project has resumed. The inflow on the 420 metre level that forced suspension of dewatering on August 12, 2008 has been remediated by remotely placing an inflatable seal between the shaft and the source of the inflow and subsequently backfilling and sealing the entire development behind the seal with concrete and grout. The 420 level is not part of future mine plans. It is currently expected to take six to 12 months to dewater and secure the mine depending on what conditions are found in the shaft and the underground workings. Cameco owns 50% and is operator of the Cigar Lake project located in northern Saskatchewan, Canada.
