Specimens in the collection of the British Museum that are labelled as coming from Virtuous Lady Mine have been shown to be really from George and Charlotte Mine. Tiny childrenite crystals were identified however on a "Lady's Slipper" pseudomorph that probably came from Virtuous Lady Mine. While the occurrence of childrenite at this locality is likely, it still has to be confirmed (Braithwaite and Cooper, 1982).
