I suppose in my mind the silver and gold are the bird in the hand ....(although I'd expect exploration to increase resource ).....with a big Cu project as the WILD card if you'll pardon the mixed metaphors .

I suppose it would depend on scale more than commodity as to whether they maintain interest longer term .
