Hm, Mining Watch Canada has their hands full with all the international bullshit that canadian mining companies get up to, so sadly they aren't blowing the whistle on this one.
Since it's a Vancouver company and a lot of folks in Vancouver have experience struggling with resource extraction firms who are violating indigenous sovereignty, I hope these folks reach out to organizations in BC. Resistance needs to put local pressure on these fuckers where they work and live, shielded from accountability by geography.
