A loose cluster of nicely crystallized native copper. In good condition. The specimen comes with a previous label from the collection of Ray DeMark.The Ray Mine in Pinal County, Arizona, is a massive porphyry-style deposit hosted within Precambrian schist and intrusive rocks that have undergone extensive faulting and hydrothermal alteration. Commercial mining activity began in the late 19th century, transitioning from early underground extraction methods to a large-scale open-pit operation by the mid-20th century. Over its long history, the site has yielded not only immense industrial metal production but also exceptional secondary mineral specimens, making it a celebrated locality for mineral collectors.
