This is a meteorite which fell in 1516 and not found until 1958. It is sawed on one side, so probably analyzed. You can actually see some alterations to a green mineral, indicating there is a component of nickel in the mineral. The Akaganeite is within the orange crusts at the top and sides and mixed with goethite.

Dull dark grey long strands of Alabandite crystals to over 3cm. This is by all accounts a very nice, choice, specimen.
A note from a fine mineralogist:
First, no Alabandite was found at the Proprietary (Broken Hill Proprietary; BHP) Mine at Broken Hill. It is probably from the Zinc Corp. (ZC) Mine, 20st Level at Broken Hill. This is where these "Plumrose Spray" crystal groups were found. Second, current research has now found that these "Plumrose Spray" crystal groups are actually Alabandite pseudomorphs of Ramberite crystals not native Alabandite crystals.
