It appears internal issues with coal pushing the price around.
It would be good if Kruiser's article compared costs with existing polish companies as the attached is what is driving prices at present.

especially as listed in warsaw as well, would assume a big dump on coal presently based on the above article.
It could work as a big positive if they can get very low costs and most other mines have closed or in maintenance. But it would appear for anything to happen coal price will need to go upward at least slightly.
Happy to hear others thoughts.
