Agnico Eagle holds to this day the rights of a portion of the historic mining sites in the  
Cobalt-Coleman Area (about 230 properties). Some of these sites were operated and  
closed well before Agnico Eagle acquired the properties. From 1957 to 1989, Agnico  
Eagle Silver Division operated 23 mines, 4 mills and 1 refinery in the Cobalt-Coleman  
Area. Closure plans (7) were developed and filed with the Ministry of Northern  
Development and Mines (MNDM) between 1993 and 1998. Closure and rehabilitation  
work was done during the same period, and extended up to 2004.  
In 2012, the MNDM asked for amendments to 1990’s closure plans. Agnico Eagle thus  
engaged in a thorough inventory and investigation of their properties. The amount of  
information gathered during this exercise called for a system to be developed to support  
data analysis. We also needed to process the information in order to prioritize  
additional/required rehabilitation actions based on criteria that would take into account  
technical and economic factors, but also environmental and socio-cultural factors. A risk  
assessment approach was selected to reach that goal.
