So is it worth buying gxy or better to put monies into DSO. With low oil prices shipping is negligible, maybe $10-20 additional a tonne (assuming iron ore charter rates). So assuming 2% lithium conc you need to ship 50 tonnes to get 1 tonne of lithium. So additional $1000. Chinese can probably process at 25% of the cost in Australia. At $10000 a tonne for lithium DSO might be worth it.
