Specimens of primary minerals from the New Glencrieff Mine are not common. A handwritten label on the specimen provinces it from the 60 Fathom level West Branch of the New Glencrieff Vein, found/acquired in 1926 (the west branch was worked to a 160 fathom leve). The specimen shows a druse of milky white Baryte crystals partly investing crystals of scalenohedral Calcite, with black crytals of Sphalerite on a druse of Quartz. The matrix is grey slate with creamy Dolomite.
