The manager of the Iron Monarch quarry discovered the mineral middlebackite. It was named for the quarry’s home, the Middleback Range in Australia, where another 163 minerals have been identified, 17 of them containing carbon. The middlebackite sample was discovered in 1990, but only characterized as a new mineral species some 25 years later when sophisticated analytical tools made it possible to identify the structure of this new carbon mineral. Type material is deposited in the mineralogical collections of the South Australian Museum, Adelaide, Australia, registration number G34300.
