Destroying rough stone?

[swirly]

Alright, so here is the situation. I often find myself with a full inventory. I'll be heading back to town and run across a mineral patch that I'd like to mine, like a copper vein for instance. Now I can take the copper ore because I already have some in my inventory and the stack isn't full. I have no use for the rough stone though and no room for it in my inventory. The problem is that if I don't take the rough stone then when I mine that patch again I'll just get the same rough stone and no copper ore. I can't take it and put it in my inventory then destroy it because I have no space. So does anyone know of a way to destroy an item from the loot screen without moving it to a bag first?

P.S. wasn't sure to put this in general or in here, but figure that a way to destory something without bagging it first might be considered a game mechanic or something similiar.
