wingellina feasibility study, page-5

Probably no rush with Wingellina. Exploration on the new deposit is proving up more resource while nickel price in doldrums. Construction costs are very high in mining at the moment, but this will abate, with current trends in the markets. Why rush in and pay top dollar when you can wait a year or three and save in a big way?
This gives time to think about power supply etc. prove up underground water, wait out the acid price squeeze.
meanwhile back in Tasmania, the tin operation is humming at a time when Indonesia and China are cutting back production, a tribal war is breaking out in the DR Congo-again, looking like closing their tin production, and so on.
Best tactic just now looks to me to be what they are doing. Borrowing or going to the market just now to develop Wingellina would probably be bad timing.
Worley Parsons have set up a solar division and plan to put in big solar power generation in the hottest areas of Australia -such as where Wingellina is. Up to 60 degrees during the day, and low cloud cover makes for some pretty powerful solar potential. Based on superheating oil in tubes heated by big polished focused discs. A Mojave style solar plant would probably run cheaper than a huge set of high tension lines from wherever. take some analysis and thinking about no doubt. No rush.
