Back of an envelope. and i'm sure my numbers will be corrected.
Well the DSO is meant to represent 1-1.5m p/a from this quarter (once approval arrives) then your talking the sale of manganese. I personally haven't done the maths, but 5 smelters over 5 years and the manganese price looking to have turned a decisive corner....
I think i recall each smelthing unit is capable of smelting 15,000 tons of fero per annum. thats (15 million kgs x $2.10USD) = $31,500,000 USD per smelter, with a plan for a total of 5 smelters over 5 years making a total revenue of $157,500,000USD per annum - costs. or
$204,227,192 AUD - Costs. per annum.
