The Eagle Mine is not an old mine. It's a new mine that failed.
Current regulations do not allow for new mines to be developed without providing some form of insurance to allow for proper reclamation once the mine is closed. All provinces will impose varying forms of bonding and so on to ensure that if a mine were to fail, the province would have the resources for reclamation in their absence.
Of course, mines themselves have an obligation to reclaim. They have to develop closure plans, which are reviewed every five years. There's a practice in our industry called “progressive reclamation”, which is that you try to reclaim as you go.
Prior to the 1970s or 1980s when these measures started to come into place, we used to build mines and then leave them, so there is a legacy of old and abandoned mines across the country. There have been efforts over the years to go back and restore some of them. One of the best examples is the Britannia Mine in British Columbia. I don't know if you're familiar with what's been done there, but it's an amazing story of how Howe Sound has really bounced back.
