A letter warning the province to cease jade and placer mining activities on their territories has been penned by the Tahltan Central Government.
According to TCG President Chad Day, the mining activities taking place around Dease Lake are causing harm to the environment.
Day also says the operations do not respect Tahltan title and rights.
Day says the TCG will take all steps necessary to shut down the activities themselves should the province not take action.
They are also calling for the province to stop issuing jade and placer claims, and address unauthorized use of access roads.
