montanhistorik.deI come from Poland and I'm interested mostly in abandoned mines exploration. I was looking for a German mine-explo community for some time and I guess I finally found it here
I think there are lots of interested mines in Germany that could be a great opportunity for us. On the other hand I'm sure you are not familiar with polish mines which means we could help each other to get a better understanding of mines and exploration opprotunities in both countries.
As far as I know polish and german communities are not cooperating so far which in my opinion could change with a nice results for both sides
