URANINITE Chandlers Mill Mine, Newport, NH 6 mm field of view. Pair of black uraninite crystals.	Species: URANINITE Locality: Chandlers Mill Mine, Newport, NH Specimen Size: 6 mm field of view. Pair of black uraninite crystals. Field Collected: Tom Mortimer Catalog No.: TBC Notes: Uraninite has not been previously reported from the Chandlers Mill Mine. This small crystal group is intensely radio-active.
ZIRCON var. cyrtolite Chandlers Mill Mine, Newport, NH 5 mm prismatic zircon crystal with prominent pyramid termination.	Species: ZIRCON var. cyrtolite Locality: Chandlers Mill Mine, Newport, NH Specimen Size: 5 mm prismatic zircon crystal with prominent pyramid termination. Field Collected: Tom Mortimer Catalog No.: TBC Notes: This small zircon crystal is slightly radio-active.
BERMANITE on Phosphosiderite Fletcher Mine, N. Groton, NH 4.3 mm field of view BERMANITE on Phosphosiderite Fletcher Mine, N. Groton, NH 2 mm field of view	Species: BERMANITE on Phosphosiderite Locality: Fletcher Mine, N. Groton, NH Specimen Size: 4.3 mm field of view, top photo Field Collected: Catalog No.: A Bob Wilken specimen Notes: [tm] This is the best NH bermanite I have seen.
GRAFTONITE Keyes Mine, Orange, NH 12 cm specimen with 9 cm zone of deep reddish graftonite GRAFTONITE Keyes Mine, Orange, NH 1 cm zoom view	Species: GRAFTONITE Locality: Keyes Mine, Orange, NH Specimen Size: 12 cm specimen with 9 cm zone of deep reddish graftonite Field Collected: Ralph Lingard, ex. Gene Bearss Catalog No.: TBC Notes: The laminar structure of the graftonite is visible in the 1 cm zoom view.
PYRRHOTITE Palermo Mine, N. Groton, NH 6 cm specimen with brown thin plates of metalic pyrrhotite on triphylite. PYRRHOTITE Palermo Mine, N. Groton, NH 8 mm zoom view of dark-bronze pyrrhotite in triphylite.	Species: PYRRHOTITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 6 cm specimen with brown thin plates of metalic pyrrhotite on triphylite. Field Collected: Bob Wilken Catalog No.: TBC Notes: This pyrrhotite is weakly magnetic, a diagnostic test that differentiates it from pyrite. Pyrrhotite is reported from the Palermo Mine.
OVERITE group Pod 3, Palermo Mine, N. Groton, NH, NH 4 mm field of view	Species: OVERITE group Locality: Pod 3, Palermo Mine, N. Groton, NH Specimen Size: 4 mm field of view Field Collected: Forrest Fogg, collected during 1970's Catalog No.: u1475 Notes: An overite group mineral suggested by EDS analysis. Overite group minerals have not been previously reported from the Palermo Mine.
GRAFTONITE Rice Mine, N. Groton, NH 12 cm specimen with pinkish-brown zones of graftonite within broken cross-sections of well delineated triphylite crystals.	Species: GRAFTONITE Locality: Rice Mine, N. Groton, NH Specimen Size: 12 cm specimen with pinkish-brown zones of graftonite within broken cross-sections of well delineated triphylite crystals. Field Collected: Unknown - ex. Gene Bearss Catalog No.: TBC Notes:
GRAFTONITE Rice Mine, N. Groton, NH 7 cm specimen GRAFTONITE Rice Mine, N. Groton, NH 5 cm zoom view of edge GRAFTONITE Rice Mine, N. Groton, NH 2 cm zoom view of edge	Species: GRAFTONITE Locality: Rice Mine, N. Groton, NH Specimen Size: 7 cm specimen Field Collected: Ralph Lingard, ex. Gene Bearss Catalog No.: TBC Notes: Two zoom views showing laminar structure.
GRAFTONITE Rice Mine, N. Groton, NH 8 cm specimen with red-brown graftonite embedded in blue triphylite	Species: GRAFTONITE Locality: Rice Mine, N. Groton, NH Specimen Size: 8 cm specimen with red-brown graftonite embedded in blue triphylite Field Collected: ex Gene Bearss - Purchased from Perham's, West Paris, ME for $8.00 Catalog No.: TBC Notes:
ARROJADEITE group Chandlers Mill Mine, Newport, NH A 6 cm specimen with pale green arrojadeite group mineral embedded in feldspar. DICKINSONITE - label Chandlers Mill Mine, Newport, NH A 6 cm specimen with pale green arrojadeite group mineral embedded in feldspar.	Species: ARROJADEITE group Locality: Chandlers Mill Mine, Newport, NH Specimen Size: A 6 cm specimen with pale green arrojadeite group mineral embedded in feldspar. Field Collected: ex Gene Bearss - Purchased from Perham's, West Paris, ME for $4.00 Catalog No.: TBC Notes: Likely not dickinsonite, (as indicated on Perham's label) but another arrojadite group member. The arrojadeite-dickinsonite group has undergone substantial revision since the 1960's. The Moore & Ito article, Alluaudites, wyllieites, arrojadeite: crystal chemistry and nomenclature , June 1979 Mineralogical Magazine contains an analysis of a "Smith Mine" specimen indicating the species of this Smith Mine mineral is arrojadeite, not dickinsonite. Collectors not familar with arrojadeite may easily mistake a specimen like this to be apatite. The "Smith" Mine of Newport, NH has been clarified to be the Chandlers Mill Mine, see Chandlers Mill mines (pdf) - Fred Davis (2013)
