The Kaiwu Mine in Hezhang County, Bijie, Guizhou Province, China, is situated within a complex regional geology characterized by carbonate and sedimentary rock formations hosting hydrothermal base metal deposits. Originally worked as a regional commercial metal mine, it gained international attention within the mineral collecting community around 2013 when exceptional specimen-grade mineral associations began entering the global market. Miners and local collectors recovered striking aesthetic combinations from underground operations, most notably lustrous brown siderite blades with brilliant metallic chalcopyrite crystals.
