Located 25 kms west-southwest of Broken Hill, 1km south of the Barrier Highway and 2.4 kms from the intersection of the Barrier Highway and the Triple Chance access road.
There was a small pit 10 metres wide by 20 metres long and 5 metres deep with euhedral almandine garnets up to 15cm across found embedded in a chloritic schist. The pit was first opened up by Alan Ireland in the 1960's and many good specimens were obtained including very large matrix pieces, over the next 40 years. The lease was passed onto his daughter when Alan died in the 1980's. In 2010, Alan's daughter sold the mining lease to Tom Kapitany of Crystal World (Melbourne) who has, after retrieving more quality specimens, pushed the dump material back into and covering the original pit. Along with the large well-formed garnets, small sharp octahedral magnetite crystals up to 6mm are found within the chloritic schists.
The chlorite schist is a retrograde shear zone cutting the local high grade felsic gneisses of mid-Proterozoic age.
