coking coal versus thermal coal, page-4

They sell both. Vlak is domestic and low quality while Penumbra (the new mine) is high as well as Ferrier.
The project economics are that Penumbra should be profitable but a decent margin (check the last announcement), then Vlank and Ferrier is probably just breaking even.
The DeWit complex will probably have both low and high end stuff, if they ever get it out of the ground.
The wild cards (Colombia coal option - dont laugh!) lol, supposed to be high end coking coal and the Botswana exploration should be on the lower end as well.
