All the miners have been similarly hammered. There's a perception that we have an over production of product which will likely depress prices for longer than we would like. This is true of aluminum and all the industrial metals as well as the precious metals and agricultural commodities. This will not last forever but I have no idea how long. It could be 2019 before we see a real recovery in these stocks. I have positions in this sector and have added reluctantly with recent weakness. In time I expect it to pay off.
