Newberyite, a magnesium phosphate hydrate mineral, was verified by [Dunn] from Sterling Hill, where it occurs associated with niahite, sussexite, and severely altered pyrochroite. It is whitish and occurs as small casts after an unknown precursor mineral and as white crystals. It was identified using only X-ray methods; no other data were obtained. Newberyite is derived from bat guano at some localities, but nothing is known of the genesis of local newberyite. It has not been reported from Franklin. (Dunn, 1995)
