Overview

South Windarra was mined intermittently by WMC between 1974 and 1992 using a combination of open-cut and underground mining techniques.  A total pre-mining resource size of 6 million tonnes of ore @ 1.39% Ni for 83,405 tonnes of contained nickel metal was defined by WMC at South Windarra.  Records show that 3 million tonnes of ore at 1.40% Ni was mined from the South Windarra Deposit, producing a total of 41,301 tonnes of nickel. 

Poseidon has calculated a JORC compliant resource estimation for the remaining mineralisation at South Windarra which is associated with the known mineralisation that was identified and left behind by WMC.  Recent geological reinterpretation and resource modelling has resulted in the resource estimation of  902,730t @ 1.14% Ni for 10,298 tonnes of nickel metal at a 0.9% Ni cut-off grade.
