Argonaut Securities and Canaccord Genuity were offering shares at 1.4¢ apiece and had room for $2 million in oversubscriptions.

Of note, Linden’s existing shareholder St Barbara would tip into the raise and emerge as 13 per cent shareholder in Brighstar. It comes after St Barbara agreed to sell its Leonora Assets to Genesis Minerals for $600 million last year.

Lastly, graphite hopeful Black Rock Mining has Petra Capital building support for a $10 million placement at 6.5¢ a share, representing a 20.7 per cent discount to the last close.
