OK so we differ in point of view.
I merely want to point out that I would prefer that the value of those other metals I would prefer if they were in the form of nockel and added on. Different metals mean more expensive processing and some of the matals instead of being extracted at 90% end up only at 80.
Second, multi metal processing is harder to control environmentally, i.e. more added cost.
I think you are looking at it psychologically, as if more metals means more, while I often see less.
To me total processed value per ton is what I look for.
Nickel is an industrial metal. Nickel price follows the economy. Economy can not be in the dumps forever. you get your value sooner or later, you just have to have decent goods in the ground.
Cheers.
