Ann: Trading Halt, page-88

Interpretation of Burwill's announcement from TheEdgeMarkets:
Burwill to pay A$25 mil for exclusive selling rights to Alliance Mineral Assets’ Bald Hill lithium

It also suggests that the deal has been signed:
"Burwill has made an initial advance payment of A$7.5 million upon signing of the agreement, and will make two further advance payments of A$8.75 million each in July and Sept 2017."

We shall await confirmation from TAW/AMAL announcement.

Also note that this deal is only for the lithium, we also have substantial tantalum credits, which will probably be another offtake party (IMO Mitsubishi).
