Read 'em and weep, ace. ROFR already triggered, per Judge Martin.
Here is his ruling, with a link to the WASC Court website so you can verify it for yourself. BTW, heck of a lot more rigorous documentation than you're providing to this thread, with your unsubstantiated claims that "two Chinese billionaires" are backing Vangom LOL.
Paragraph 240: Consequently, at May 2017, an ROFR offer ought to have been made in parallel terms by both Vango and DPPL to Billabong Gold(DPPL in this May 2017 transaction is named as a party) to BillabongGold.
Paragraph 241: Towards this May 2017 occasion, I assess there to be a joint breach by both defendants by their omission as regards OTA cl 12.6(b)vis-à-vis Billabong Gold (albeit the second defendant is a 100%subsidiary of the first defendant, Vango).
