Mt. Monger Station, Western Australia, Australia

    There is an increasing amount of evidence that some near surface gold is the product of biologically mediated deposition, involving plant derived compounds that assist in mobilization and deposition of metallic Gold. Some of the features displayed by this specimen, nicknamed "The Lightning Bolt" by the discoverers, are irregular cylindrical features running lengthwise down the piece. The sandy material from the walls of these features is very similar to material that accretes around tree roots in desert regions, where it has been associated with transport and deposition of Copper and Aluminum ions. Whether biological or strictly chemical, the appearance of this elongated structure revolves around numerous "fins" that are the edges of the hollow areas already mentioned. Luster is a combination of a hackly version on one side of the piece with a smoother "leaf" type on the obverse. The sandy 'matrix' is only present in the recesses of those same hollow areas. This is a very impressive display specimen - it has a very large surface area for its weight ratio. It comes complete with a custom labeled acrylic base. Total weight is 22.66 troy ounces. See the 360 degree video of this specimen which is available online.
    Overall Measurements: 9.72 x 1.57 x 1.32 inches (24.7 x 4.0 x 3.37 cm)
