Located 1.5 kilometres south east of Dowerin, 100 metres west of the Dowerin-Meckering Road, in the middle of a wheat field. It is on private property.

Discovered in 1930, but was soon abandoned as uneconomic. In 1991, the owner of the farm called in the Department of Mines to assess the deposit, but they came to the same conclusion as the original miners. It was the first discovery of chrysoberyl in Australia.

Both normal chrysoberyl and the alexandrite variety are found. The site shows plagioclase quartz-biotite-garnet gneiss, and cross-cutting tourmaline-plagioclase veins, situated adjacent to lenses of actinolite-cummingtonite-plagioclase schist, and closely intergrown with biotite and/or zincian-hercynite in the host rock gneiss.

Despite its complex and interesting geology, the chrysoberyl found is poor by world standards, and generally not of gem cutting quality. The biotite tends to dis-integrate when washed leaving the harder chrysoberyl nodules, and these are normally a cloudy pineapple colour. Alternatively it is found in thin stringers of andesine-quartz-biotite-almandine gneiss, with the chrysoberyl being green-yellow in colour.
