I'm amazed nobody has yet suggested ACB. A-Cap Resoures are sitting on one of the world's Top 10 uranium resources, in Botswana, one of the world's most stable and mining-friendly countries, with access to most of the vital infrastructure needed. They also have a huge coal resource too, to provide extra cash flow.
Can't see too much to go wrong on this one, currently under 5c, but could be a real multi-bagger. One of the best potential exploders on the ASX, in my 'umble opinion.
