Vote for your favorite mineral in #MinCup26! - Sphalerite vs. Anorthite Both zinc ore Sphalerite and calcium plagioclase feldspar Anorthite have perfect cleavage that will split cleanly if you hit them with a hammer, but only one can claim a larger split of your votes!
Redgillite was confirmed on one specimen (19/05/2025 XRD)collected from the Broadlaw Low Level. The redgillite is associated with confirmed bechererite, visual id leadhillite and possible 'new mineral' looks like namuwite, which has given an odd XRD result.
Quality for species:
Poor for species, only of interest for locality collectors. (#)
