Looks like it's lignite guys, but apparently a lot of it.
Wouldn't have a clue what to value this at at this stage but what a trader.
From Google:
"Lignite is a geologically young coal which has the lowest carbon content, 25-35 percent, and a heat value ranging between 4,000 and 8,300 BTUs-per-pound. Sometimes called brown coal, it is mainly used for electric power generation"
