Medieval Mines

 

I'm pretty much looking for any imformation, but some things like how much a certain mine could mine per year or so. Like how much gold would come from one gold mine, or how much from a silver mine, etc. How many people would work a mine(of course each mine would be different, but what was the normal, or maybe the largest or smallest). Which kingdoms had what kind of mines, or which were more common and less common in any given nation.

 

Hopefully I gave enough, I don't know if anyone can help me on this one, but anything would be useful. Thanks.
