From the third paragraph...
"Our estimated NPV10 (un-risked) for SYT is A$260m or 9c per fully-diluted share. Attaching a 50% discount for forecast risk (lack of visibility on timing and quantum of sales revenue, margin, capex), we calculate a risked NPV target price of A$130m or 4.5c per fully-diluted share "
I think we're all risk takers here aren't we?
