Specimen data for Xanthoxenite

Tom Mortimer catalog number: 1536

Identification method: Purchased from Excalibur Minerals, Peekskill, NY, Aug 11, 2006, East Coast Mineral show. Given Excalibur was the source for this specimen, I greatly trusted the identification. Reviewing the xanthoxenite species in 2024 and knowing Tony Nikischer of Excalibur performed EDS for many years I contacted Tony to inquire if he had analytic data to support the identification. The label accompanying the specimen had a blacked out name of Curten Mineral Co. Forwarding this information to Tony, he replied: "The late Forrest Cureton was the king of rare species dealers, and his identifications were consistently excellent. He relied on authors, analytical work by the late Dr. Sidney Williams of Phelps-Dodge, Andy Roberts, chief X-ray mineralogist at the Geological Survey of Canada, and many other competent scientists. I have a very high level of confidence in his material."

Notes: Palermo is the co-type locality for Xanthoxenite.
