"Before" photo (left) of Rio Algom's (now Billiton) Pronto Waste Management Area near Elliot Lake, taken in 1998 is shown on the left.  The "after" photo on the right was taken in 2002, and shows successful reclamation of these acidic, fine grained copper tailings through the use of papermill sludge from St. Marys Paper Ltd. (Sault St. Marie, Ontario). The gray area on the right side of the 2002 photo is fresh sludge that had just been applied.  (Photo courtesy B. Tisch, Natural Resources Canada)
