Woodlawn Mine Cerrusite (lead carbonate) crystals in earthy gossan from original Woodlawn Mine exploratioin costeans circa 1971. Field of view approx. 15cm.

The Woodlawn deposit was discovered in 1969 by Jododex Australia Pty Ltd, a joint venture between two American companies, St. Joseph International (St. Joe Minerals Corp), the largest lead/zinc producer in the USA and Phelps Dodge, a large copper producer.

Mining of the open cut commenced in 1978 with CRA (now Riotinto) becoming the Australian partner in the mining joint venture. The open pit resource was exhausted in 1987 and the mine went underground via a single portal and decline. The Amewricans withdrew from joint venture and CRA sold the mine to Denehurst Ltd who mined the underground till the closure of the mine in 1998.

During the life of the mine 13.1Mt of ore was mined at a grade of 9.1% Zn, 3.6% Pb, 1.6% Cu, 74 g/t Ag and 0.5 g/t Au.
