Marked to market valuation today, page-29

I don't get the market at all, and I know that there a heap of investor smarter and more knowledgeable than I am, so please can you tell me why GXY should be at the current price.

I mean, let assume the other half of SDV is the same value which we sell to Posco.
SDV ($280 mil us = $395 mil Australia ) + we will have $450 mil shortly from the first sale and our current asset, that in total give us = $845 mil (Australia) and our current market cap is $921 mil?
so does that mean Jame Bay and Mount Cathlin is only $76 mil?

Mount Cathlin is giving us at least $30 mil of net profit every year, even with the Q3 hip up?, so for 2 and half years Mount Cathlin can pay this $76 mil off and you can have Jame bay for free?

All this with the current lithium spot price in China rising back up or staying stable?
EV continues to growth?
Is the SP down because the investor doesn't like the direction GXY taking in regarding to developing SDV?
