- mining kimberlite pipes which are actually cones, so smaller and deeper (eventually underground mining)
- even if the mines are well-done in Canada, they're done by De Beers which may not be so great elsewhere
- huge excavation: destroys land, how do you fix? what about tailings?
- 1 carat from 1 ton of kimberlite from 10K tonnes of rock
- crushing, washing and screening; no chemicals
- debeers checks: soil, vegetation, wildlife, air, water & energy conservation
- objective : identify & mitigate impacts during planning & operation, leave productive, self-sustaining, hazard-free
- iso 14001: having an enviro mgmt policy
- de beers committed to enviro, community eg in town hall meetings; how to herd caribou, fence off etc
- ekati then diavik, jericho, soon snap lake, victor (ontario)
- diavik: caribou right-of-way, water collection/treatment
- diavik owner: Environmental, political, safety and labour rights concerns have been raised against Rio Tinto by both environmental groups and unions
