Can't Find any Coal Mines

[NrG8]

Hey there,

I'm lvl 25, I've Sent my geologist 9 times now but he's not found any coal deposits! A friend of mine found a coal deposit lvl's ago (lvl 17 ish i think). I've opened the top left of the map where i know there's coal deposit.

Any Ideas?

Did you also build a storehouse in that top left sector? :)
