Ore values at Pebble are reasonably estimated to be worth 500 (b)illion or even double. 19% of 500 (b)illion = 95(b)illion. That universe!
How much immediate cash value that has, depends on the bids ... but certainly for the next 100 years, that Native corporation would have been on easy street. Most importantly, they would have had the power of at least one of their own, on NDMs board of directors, to prevent harmful practices in Pebble's operations.
