Re: Pyrite mines in NH?
Probably the Davis Pyrite Mine in Rowe. Lots of places to look in MA and NH try Mindat and search localities with query like "Pyrite_NH or Pyrite_MA". I have found Pyrite here in RI at Conklins Q and Portsmouth in the shale beds next to fossils. Not sure abut Ruggles and pyrite as this is not a Sulphide locality as far as I ever heard.
