complete and utter BS - how in the world would they know where it came from. That gold will be put on the open market and bought and mixed with other sources.
Just corporate BS trying to jump on the green bandwagon. Besides they currently buy gold that came from mines that have destroyed other ecosystems, it just wasn't from North America so who cares right
As a side note, if anybody wants to save wild salmon - boycott farmed salmon its the best thing a consumer could do to help this fish.
