I would think that it is, but it seems like a bottom-less pit (in terms of buying with a share price seemingly 'always' going down)...
Holding some already but it is starting to get attractive...surely coal can't be that bad...
TO buy the ASX listed or NZX listed stock is also another question on my mind (given a weaker currency now, and also that they are going to be covered to ASX only shares soon as well)
