Requirements: Mining Level 60
Location: In Falador east of the southern bank, underground

The Mining Guild is a good place for coal mining because there are 20 coal rocks. On the southern side there are also three mithril rocks and that's all there is.

You can enter the Mining Guild from two places. In Falador, there is little house east of the southern bank with a dwarf standing at the door. Try to climb down the ladder and if you've got enough mining levels you get in. And the Dwarven Mine entrance which is on the southern side past the scorpions. There is also a dwarf at the door here.

If your mining level is not at least 60 they both say, "Sorry only the top miners are allowed here". Tip: If your mining is 59 you should use dwarven stout and go in because it's really easier to mine coal there than anywhere else.
