This mining district (not a mine, as erroneously reported in some sources) has produced wonderful specimens from various levels of four shafts: #31, #46, #55, #57.
Production is from sedimentary rocks of Permian age over an area of approximately 10 x 10 km.
One of the mines is a Late Bronze age copper mine.
"The Dzhezkazgan sandstone copper deposit consists of 10 ore-bearing sandstone members, numbered 1 to 10 from stratigraphically lowest to highest, within a 600 m Pennsylvanian stratigraphic section (fig. 4). Two to four ore-bearing sandstone beds occur within each ore-bearing sandstone member, and these beds and their incorporated ore bodies (“Mineralization” in fig. 5) are given the sandstone member numeral and a Roman numeral increasing from lowest to highest. Ore bodies extend over an 80 km2 area, with distinctly different distributions for each ore horizon (fig. 5). Ore bodies occur within the dipping ore-bearing section over about a 550-m vertical range from 400 m above to 150 m below sea level (Daukeev and others, 2004). Arcuate (concave to east-northeast) ore bodies 2-I, 4-I and 6-I (fig. 5) occur at progressively higher stratigraphic levels down the plunge of the Kingir Anticline to the west-southwest but at roughly similar (±100 m) elevations (fig. 6). Stratigraphically higher ore bodies (8-I and 9-I in fig. 5) have elongate, northeast-trending shapes along and parallel to the sharp, south-southeast-dipping limb of the Kingir Anticline."
