Off the top of my head, you could look at Detour Gold, the De Beers mine, the Victor Diamond Mine, and the Musselwhite Mine. There are a number of signings between the industry and Moose Creek, Mushkegowuk Council, and Attawapiskat.
That's what I'd be prepared to say about actual successes, where the communities and the industries have actually come to an agreement and they're providing prosperity to each other.
