I'll start off today with a specimen from the mines at Trepca. There is active mining at this deposit again, so I hope we will see many more nice specimens from there in the future. The last piece is a heulandite from Iceland that was once part of the Washington Roebling Collection which went to the Smithsonian. I am very happy to have this piece as well as the accompanying labels.

Today's post include a few specimens from the Madan orefield in Bulgaria. This polymetallic deposit has been known since ancient times and includes a large number of mines. Although many are now closed, there are still several working mines and specimens are still being recovered from a few of the closed mines. I have been working on assembling a representative suite of specimens from the Madan, Zlatograd, and Laki Districts for about the last 20 years and will start off with several from the Madan District.
