Locality: Franconia, NH
Specimen Size: 3.5 mm crystal
Field Collected: Acquired by Gene Bearss through trade. Gifted to Tom Mortimer
Catalog No.: TBC
Notes: A nifty little crystal. It would be valuable if more was known about its history and locality. Gene stated he acquired this specimen from a 1976 swap. The label said "Cobaltite." Lacking NH cobaltite specimens in other collections, the cobaltite identification of this specimen was suspect. However, a historical reference (Hayes, American Journal of Science #24, pg. 386, 1833) to cobalt rich arsenopyrite ("Danaite") in Franconia, NH gives some credence to a cobaltite identification. Mindat includes a page dedicated to cobaltian arsenopyrite: ( mindat.org link) giving a chemistry ranging from (Fe0.90Co0.10)AsS to (Fe0.65Co0.35)AsS
Philip Morrill in his New Hampshire Mines and Mineral Localities lists "danaite" for both the Franconia Iron Mine (listed under the town of Lisbon, but it is actually in Sugar Hill) and under "General" minerals for the town of Franconia.
A January, 2014 EDS analysis showed this small crystal to be arsenopyrite, but with a small measurable amount of cobalt, very likely exceeding the ten percent substitution required for danaite. Therefore, it is reasonable to identify this specimen as "arsenopyrite var. danaite."

Catalog No.: A Gene Bearss collection specimen
Notes:
Locality: Palermo #1 Mine, N. Groton, NH
Specimen Size: Pair of 2 mm clear whitlockite crystals

Locality: Palermo #1 Mine, N. Groton, NH
Specimen Size: 2.5 mm Foggite ball
Field Collected: Walter Lane 1995-96, Cat. #2394
Catalog No.: A Gene Bearss collection specimen
Notes: The square terminations of the individual foggite crystals are clearly evident here. This is a classic foggite crystal spheroid. Apatite also forms spheroids at the Palermo Mine and may be confused with foggite, but the apatite balls lack the square plate terminations.
