BIG RIVER SHAREHOLDERS VOTE IN FAVOUR OF ACQUISITION BY AURA

Big River Gold Ltd. has stated in a press release that the requisite majorities of each class of shareholders voted in favour of the proposed scheme of arrangement, pursuant to which Borborema LLC, an indirect wholly owned subsidiary of Aura Minerals Inc. (BidCo), will acquire all of the shares in Big River (other than the shares held by Dundee Resources). As previously disclosed, Aura will hold its interest in BidCo through an intermediate holding company (JVCo) with Dundee Resources, which agreed, subject to certain limited conditions, to receive shares in JVCo, in lieu of the cash consideration, in order to indirectly maintain an equity interest in Big River and form a joint venture with Aura.

Further details of the transaction shall be informed in a specific press release after the confirmation of approval of the scheme by the Supreme Court of Western Australia at a second court hearing scheduled for Sept. 8, 2022.

Next steps

Big River will now seek approval of the scheme from the court at the second court hearing.

If the court approves the scheme at the second court hearing, it is expected that the scheme will take effect on Sept. 9, 2022.

Scheme implementation is expected to occur on Sept. 20, 2022, subject to the satisfaction or waiver of the remaining conditions precedent to the scheme, including approval by the court at the second court hearing.
