The Green Dragon Mine is located 5 kilometres north north-east of Thaduna. It was discovered about the same time as Thaduna, and worked as a satellite operation to this mine. The abandoned open pit is 330m long by 70m wide, with adjacent mine waste dumps. There is also a historic 6.1m deep shaft, and a stope from the eastern side from which 200 tonnes at 8% copper was extracted between 1967-1968. The deposit is hosted by similar rock to Thaduna, with mineralisation being cuprite, chalcocite and malachite as a 50m east-west shoot. The supergene zone shows malachite, with lesser amounts of azurite, and cuprite.

The deposit is situated where two intersecting shears meet under the laterite capping. The source states in total there are three closely spaced shears trending east-west, the mineralisation 0.5-5.2 metres wide, with supergene mineralisation down to 53 metres from the surface.

Ore from the mine was blamed for the closure of the Thaduna plant in 1970, when it was mixed with Thaduna mine ore, the plant unable to cope with impurities from the Green Dragon material.
