Lustrous crystallized native copper exquisitely set up on a brecciated matrix. This is in super condition all around and in excellent large display quality example for the species from this locality.
The Itauz mine, situated within the Zhelandy ore field of the broader Dzhezkazgan region in the Karaganda Region of Kazakhstan, began modern industrial development and quarry operations around 1998 and remains active today as part of the major copper-producing operations managed by Kazakhmys. Geologically, the deposit is hosted within the extensive Dzhezkazgan-Sarysu sedimentary basin and is classified as a classic cupriferous sandstone and shale deposit. The mineralization occurs primarily as stratabound copper sulfides (such as chalcocite, bornite, and chalcopyrite) disseminated through thick sequences of Upper Paleozoic red-bed terrigenous sediments, accompanied by significant associated values of silver and osmium.
