Here's the section from the September quarterly when the raising was completed:
"Strategic investment secured with leading Indian mining conglomerate the Vimson Group, through its Singapore-based,wholly owned subsidiary, V. M. Salgaocar & Bro. (Singapore) Pte. Ltd., for a strategic investment into TNG of approximately$10M (before costs).
Share Purchase Plan (SPP) announced to raise up to a further $5M, enabling eligible shareholders to participate in TNG’scapital raising on terms which are as close as possible to the Vimson Group subscription agreement"
We still haven't been told why. Especially given how close the board have said we are to finalising offtakes and finance.
