i can't find any Mining points

[Tristan]

I walk around now days in a row but I find no mining points
anybody knows what I do wrong?

[kLauE]

nothing, most mines are already built. try the outer supergrids!

[Peter]

They're all taken. What you did wrong is that you didn't get to the rustroot two days after the game started thanks to grinding your brains out. This is intended; you're supposed to trade for metal. Farm silk and/or huge quantities of linen, or else go to the very edges of the map and hope you get lucky.
