Specialist hard-coking coal prices around the world bode ill for the likes of debt-laden Solid Energy and litigation-bound Bathurst Resources, and their respective West Coast operations.
Since 2011, hard-coking coal has plunged in price from US$290 ($367) a tonne to about US$140.
Similarly, lower grade thermal coal (on Newcastle prices) for energy generation has gone from US$121 a tonne to about US$94.
Hard-coking prices in 2008 were 60 per cent higher at US$350, a period when Solid Energy was investigating speculative fossil fuel alternatives, and were still about US$330 in 2011.
However, Solid Energy was plunged into crisis in March because of the declining global coal price, shedding hundreds of staff and revealing about $390 million in debt, while Bathurst is fighting in the courts over consent challenges.
