Already hold a good size, and quite underwater, position in AUNFF. Don't forget CSI.TO on your list. I think it is also "stupid cheap" at these prices.
Who really knows? If you look at multi year charts on most of these what have they done? The best you can do is hope to trade, but this is precisely why I have abandoned the sector. I spend several years investing in mining companies and it's usually pure punishment. No matter how much higher gold and silver, etc. are relative to a few years back, the miners themselves do squat. Please correct me if I'm wrong.
