Can someone please explain, page-4

hi Pamplona.
Anthony Tse has since updated the all-in production of spodumene to $260/t AUD.
The old figures are outdated and rely on some other method of making the calculations. I'm not exactly sure of the method but I'd presume Tantalum production and/or some LOM equation or something that lowers the overall per tonne price.
The recent figures from Anthony Tse come from an April 2016 interview and can be presumed to be the most accurate that we have been given so far. If you need a link I'll dig it up for you tonight.

Also worth noting that this is an old document and the throughput rate, expected income etc is no longer accurate either. The mine was operating at above 137ktpa spodumene production when it was decommissioned in 2012. Michael Fotios has now set the goal of it being ramped up from an initial start-up phase of 80kt to between 200-250ktpa.
