RE:what we need for a higher SP? it's really simple...Inventories of zinc and copper and other base metals will be put under even more pressure, given all the rebuilding that will be necessary in places like Texas, Florida and other places affected by Harvey and Irma. Sorry to be so callous, but that's the reality here from these natural disasters. This will support higher base metal prices at least for the foreseeable future. The added debt in the US, and other geo-political hot-spots around the world, will go to supporting higher gold prices. Base metals and gold is the place to be right now. NSU has had its issues over the last year, but the future actually looks pretty good.
