This article appears to be a dictionary definition. Please rewrite it to present the subject from an encyclopedic point of view. (May 2023)

Plumosite is a questionable mineral. Most of the time, it can refer to any feather ore, i.e. any ore that forms fine capillaries within the surrounding rock.

Older specimens could be either boulangerite, jamesonite or zinkenite (Pb₂Sb₂S₅, sulfosalt mineral).^[1][2][3]
