Devilline, a calcium copper sulfate hydroxide hydrate mineral, was reported from Sterling Hill by Cook (1973). He found it as bluish-green coatings and feathery microcrystals associated with brochantite, linarite, and gypsum.
Devilline was subsequently reported by Jenkins and Misiur (1994) from below the 700 level at Sterling Hill. It has not been reported from Franklin. Devilline is a rare mineral locally.
