I mean the small caps / smaller mid caps including a number of explorers in the Bowen and Surat basins. (speculative - hence risky - but with very substantial upside if you put them in the bottom draw for a few years - potential future multi-baggers). A couple of overseas coaler (ASX listed) are worth looking at also.
I don't mean Whitehaven , Gloucester and other large mid caps as the sp pretty fully priced in in terms of ev/tonne.
