R3D Copper Sulphate Plant Restart, page-2

The plant is for producing copper sulphate and not copper as per se. Currently copper sulphate price is about 1/3 of the LME copper price. (US $2 to $3 k per tonne) If all goes to plan, along with the extra revenue from the zinc slag in Tasmania (Unsure how many tonnes of zinc slag there is left, google earth shows a very depleted site compared to historical satellite images of the site) then perhaps $8 to $24 million revenue per year, which hopefully will fund explorations in a heavily under explored part of Australia and produce a couple of mother loads for shareholders.
