Uranospinite, a calcium uranium arsenate hydrate mineral, was found as a light yellow post-mining encrustation on graphite-bearing calcite from the 1100 level at Sterling Hill; it has not been reported from Franklin. It was verified employing X-ray methods. Uranospinite has a moderate green fluorescence in shortwave and longwave ultraviolet. (Dunn, 1995)
