These ones. I'm either holding or rate very highly.
Cheap Potash - TRH/RDM (even with their big moves today)
Cheap Iron - MEP
Cheap Coal - MTE/EER/HDG/MOZ
But when it comes to buying a cheap stock, you forego the attached safety that some slightly more expensive explorers may have. It all comes down to risk vs. reward.
If you want a resource stock with long term safety that is reasonably cheap...
Cheap/Safe Potash - Given the 'bubble' like nature of the commodity at present, I'm not sure if there is such a thing. Not saying potash is bad, just saying that you want to see sustainability in current prices before diving head first into the thing.
Cheap/Safe Iron - CAP
Cheap/Safe Coal - EOC/CCC
Note: All these companies are speculative so I use 'safe' as a relative term.
