Ann: Burmeister Lithium Potential Defined, page-6

Delta also has a Yinnetharra JORC but yes the MC to the size of the potential deposit has huge upside for TG6.

There will be commentary by some that you need huge Mt volumes to be viable. Most of the time these will come from individuals holding shares in a deposit that is known or expected to shift to be in the 100Mt+ category. You don't need that size for the economics to work, if the ore you have defined is able to be recovered at sensible strip ratios and doesn't have bizarre processing/transportation costs.

So at say US$1,000/t for SC5.5, how much revenue would a mine 15Mt @ 1.2% mine potentially generate? Many would probably have a default guess in the mid-hundred's of millions (which is why they think you need the 100Mt type sizes to fund the capex).

15Mt * (1.2%/5.5%) * 70% recovery = 2,291kt of SC5.5. If this was sold at US$1,000/t and the exchange rate was around US$0.65 then the revenue is A$3.5b. There's obviously all the time value of money, mining, processing and capex costs to come out of that, but the starting potential revenue figure is big enough that this size can be economic.
