Old Mine, Chester Emery Mines, Chester, Hampden Co., Massachusetts, USA

StandardDetailedBy ChemistryMineral Photos (2)Site Photos (1)Search Google

This mine is the most extensive of the mines in the group, and it is the mine which has received the most attention from collectors and scientists over the years. Nearly all of the mineralogical studies which have been undertaken in regards to these mines have been done using samples from the Old Mine - very few samples from any of the other mines have been analyzed.
