Name:Named by Pete Dunn in 1981 after Ogdensburg, New Jersey, USA, which is the borough where the Sterling Mine on Sterling Hill is located and where the species was discovered. (The combined name "Sterling Hill Mine" is incorrect.)


Found as somewhat earthy looking thin coatings usually on willemite-franklinite "black ore" at the type locality. Many ogdensburgite and yukonite specimens have been confused and are incorrectly labeled. At the type locality, Ogdensburgite formed with its perfect cleavage perpendicular to the growth surface, although high magnification is needed to see the apparent fibrousness of the ogdensburgite. Yukonite does not show the fibrousness and shows a uniform to waxy appearance.
