It doesnt work very well in German.
I'm sorry about that. Maybe you should try out a translation into English.
There is the website METEORYT MORASKO run by the University of Poznań
meteorytmorasko.amu.edu.pl/rezerwat.html, but it deals mainly with the events centered around the 100th anniversary of its discovery with the two lectures of prof. J.T. Wasson of the University of California given in Poznań in 2014 (no podcast of the lectures unfortunately)
The area is now a natural reserve, so I am not sure if any unauthorized digging is allowed there. The piece I mentioned in an earlier post is the biggest one of this meteorite found so far. It was found in 2017 by Andrzej Owczarzak and Michał Nebelski outside this natural reserve.and weighs ca 271 kg after cleaning.
A good English google translation can be obtained of this site:
