Sorry to see ZYL share price dropped due to some issues and hope shareholders can recover at some stage.

I'm not a coal expert, I have a question regarding "Anthracite", because when I search the web, seems carbon should be between 86% to 98%, CV should be close to 15,000 BTUs-per-pound (8300kcal/kg)

ZYL's coal carbon below 80%, CV just around 7000kcal/kg after washed.

Just a little bit confused, any other standard to define “Anthracite”
