WTS crap copper for crap tin

[Darthjew]

I've found 16 (!!!) copper spots, not to count the prospected ones, and no tin spot so far, Im tired and frustrated, and want to trade copper for tin. Have 1 cupboard and can always mine more.
The q of bars is 37-40.
Im offering 1 bar for 1 bar of q30+ tin.
Or 2 bars for 3 bars of q10+ tin.
Or 1 bar for 6 ore of q10+ tin (please mine with industrial character).
I will use your totem.

Can also offer curiosities like Flotsams or Edels.

I had that same problem, try prospecting for tin in your cave then make another shaft inside of it to go down to level two.
