Described as located on the eastern flank of the Gregory and Isabella Ranges, extending north north-west. Ridges are capped by veins of white quartz, across an area of 150 kilometres. It was first discovered by Newcrest in the early 1990's.
The veins are 30 to 50 metres long, up to 100 metres wide. The quartz is banded, crustiform, colloform, breccias and highly irregular stockworks. The quartz contains crystalline forms, amethystine, with disseminated to banded very fine pyrite, and platey calcite replaced by microcrystalline quartz.
While decent quartz specimens appear likely, the writer warns the area is very remote, lacks any access, desert with no water or human habitation within hundreds of kilometres. The world is not lacking in fine quartz specimens, with a cheaper and safer option is buying one from another part of the planet from the comfort of your home.
Due to the extensive coverage of the quartz veins, the Mindat co-ordinates mark the general area, in particular they are sited on Koongaling Hill.
