While a modest number of whitlockite specimens have been found by collectors at the Palermo mine, it is a very rare phosphate in other New England pegmatites.
WHITLOCKITE Palermo Mine, N. Groton, NH 2.0 mm clear crystal WHITLOCKITE Palermo Mine, N. Groton, NH 2.0 mm clear crystal	Species: WHITLOCKITE Locality: Palermo Mine, N. Groton, NH Specimen Size: 2.0 mm clear crystal, with line drawing second photo Field Collected: Bob Whitmore - from a tub of Palermo phosphate rocks gifted by Bob. Catalog No.: u2448 Notes: [tm] The crystal shape suggests wardite, but the crystal lacks the lateral striations that are usually present on wardite. Palermoite and type 3 goyazite were also found in proximity to this crystal. Jim Nizamoff opined: This "is most likely whitlockite based on the appearance and siderite host. In my experience wardite mainly occurs in the hydrothermal quartz veins and is usually found with/near altered albite (probably source of the Na)."
WHITLOCKITE Fletcher Mine, Groton, NH 2.1 mm field of view	Species: WHITLOCKITE Locality: Fletcher Mine, Groton, NH (per label with gifted specimen) Specimen Size: 2.1 mm field of view Field Collected: Clayton Ford. A gift from Gordon Jackson Catalog No.: u1975 Notes: Another whitlockite group on specimen u1975. During a May, 2022 discussion on these Fletcher Mine whitlockite specimens with Jim Nizamoff, he expressed some reservations about attributing these specimens to the Fletcher Mine. He was not aware of a whitlockite occurrence at Fletcher and opined that the pegmatite chemistry of Fletcher did not well match that needed for whitlockite formation. Jim felt the possibility that these specimens were comingled with Palermo specimens was a strong possibility.
WHITLOCKITE Fletcher Mine, Groton, NH 1.4 mm crystal	Species: WHITLOCKITE Locality: Fletcher Mine (?), Groton, NH Specimen Size: 1.4 mm crystal Field Collected: Clayton Ford. A gift from Gordon Jackson Catalog No.: u1975 Notes: Chemistry computed from EDS analysis is Ca_7.55(Na_0.74Mg_0.71)P_7.0O₃₇ normalized for 7 P. For whitlockite chemistry, Ca₉Mg(PO₃OH)(PO₄)₆ . The chemistry of this specimen suggests moderate substitution by Na for Ca and/or Mg. See locality source caution with above photo.
WHITLOCKITE Palermo Mine, Groton, NH Large crystal is 1.8 mm.	Species: WHITLOCKITE Locality: Palermo Mine, Groton, NH Specimen Size: Large crystal is 1.8 mm. Field Collected: Clayton Ford Catalog No.: u2584 Notes: Water clear crystal. The color comes from siderite matrix behind. From a stack of 70 images with Canon MPE-65 lens.
WHITLOCKITE Palermo Mine, Groton, NH 3.5 mm crystal WHITLOCKITE Palermo Mine, Groton, NH 3.5 mm crystal	Species: WHITLOCKITE Locality: Palermo Mine, Groton, NH Specimen Size: 3.5 mm crystal two views Field Collected: Jim Nizamoff Catalog No.: Gifted ? Notes: Water clear crystal.
WHITLOCKITE Palermo Mine, Groton, NH 3.5 mm field of view WHITLOCKITE Palermo Mine, Groton, NH 3.5 mm field of view	Species: WHITLOCKITE Locality: Palermo Mine, Groton, NH Specimen Size: 3.5 mm field of view. Front and side views Field Collected: Jim Nizamoff Catalog No.: u2583 Notes: Water clear tabular crystal. Tabular whitlockite is uncommon.
