Silver Ore

I have been searching high and low for silver ore for our guild and for the shops in Thebes for some time now. I finaly came across a stock of 4 lumps which i purchased at inflated prices unfortunately, on my return to Thebes, i discovered that i could not remove the ore from my horse!!! It is still stuck there as far as i know. Meanwhile, i assure you, the hunt continues. (The Baron command for purchasing ore in Thebes is not working - hence the lack of silver ore in Thebes)
