One of Canada's indigenous groups, the Tahltan Nation of British Columbia, has declared that all jade mining within its territory must cease. The Nation is located in prime jade country, the Dease Lake area.
Some 25 companies are active in jade business in the area. The Tahltan Nation apparently seeks to "co-manage" commercial operations, which would seem to provide them with a substantial piece of jade action there.
Making a cultural claim to jade or other resources is not uncommon among First Peoples of various locations, for example no jade can be mined in New Zealand except by Maori people and may not be exported without government approval.
Here is the Tahltan story.
