This meteorite was found by Inspector of Mines A.W. Winzer in 1917, about 80 kilometres south of Youanmi, and then presented to the Western Australian Museum. Note: that Younami is located in Sandstone Shire.
Simpson in 1938 gave the location as 80 km south of Youanmi. Ina later publication, by McCall & De Laeter in 1965 gave the locality as 80 km north of Younami.
A mass of 118.5kg (48cm x 46cm x 15cm) was discovered. Two one-kilogram slices were removed from the mass for study.
It is 19cm x 18cm x 6cm.
The surface is deeply and broadly pitted, with several holes from burnt out troilite. The crust is fused hematite and magnetite, the magnetite also penetrating deeply into cracks. The meteorite show imperfect crystallisation, and is a medium octahedrite. It contains kamacite plates 0.5-1.0mm, and small amounts of schreibersite.
