I owned HBM shares for a long time but they IMO have made major missteps in buying Rosemont, which will likely never be permitted, and in buying and developing Constancia, for which they grossly overpaid. And their decision to break their promise and truck the ore from Constancia has made them a lot of enemies in the surrounding areas, usually a recipe for big problems in that part of the world.
But you are right, they are a bit of an outlier on that list, but that is because, unlike the rest, think their balance sheet problems are yet to be manifest.
