How long would it take me to mine 33k exp of coal?

You'll only need to mine 660 coals, probably not longer then half a day.

It would take you under 2 hours mining iron and banking the ore (under 1 hour if you dropped the ore), don't know about coal, but I do think it is slower. And your mining level matters, too, I'm pretty sure :)

I can mine about 700 per hour at the mine field north east of Yanille. There's three rocks perfectly placed together and 700 ores per hour is easy even without too much concentration.

thanx for the help
