There's more than two or three dimensions to the concept of met coal quality.
The chart below of vol/CSR is only two dimensional.
The reality is that there is also fluidity as an important aspect of the blend, its correlated with CSN.
I don't have the data to plot the graph, but, the blend/availability of the coals changes the price/demand curve in the marketplace.

This is a long term play by BHP/Glencore to corner the met market.
Note the Glencore move on Teck assets.

It's my conclusion that it's everyone's interest that BHP is left bag holding the mines they're trying to offload.
BHP has very poor mining practices due to the size of their operations.
The only way to extract resources more efficiently is if BHP has a pineapple shoved where the sun don't shine.

Final image isn't all that relevant, but, its from a collection of conference papers that I've assembled over the years ... so yeah... do you really want to ignore me...
