This specimen has hundreds of micro Bournonite crystals in a large 3cm long aggregate. The oldest label which accompanied the mineral and attached to the Kristalle label states that it is "mullerine" from Nagyag, which is a synonym of Krennerite. This is definitely not Krennerite, but we will keep the label with the specimen.
