Transaction Highlights

  • Aura to acquire 100% of Big River and form an 80%/20% joint venture with Dundee Resources
  • Big River Shareholders (other than Dundee Resources) to receive A$0.36 in Cash Consideration for each Big River Share held, which values Big River at a purchase price of approximately A$91.7 million (on a fully diluted, equity basis1)
  • Dundee Resources, a 19.3% Big River Shareholder2, has executed a Cooperation and Commitment Deed with Aura pursuant to which Dundee Resources will (subject to certain conditions) ultimately hold a 20.0% indirect interest in Big River

ROAD TOWN, British Virgin Islands, April 19, 2022 (GLOBE NEWSWIRE) — Aura Minerals Inc. (TSX:ORA, B3:AURA33) (“Aura” or the “Company”) is pleased to announce that it has entered into a binding Scheme Implementation Deed (“SID”) with Big River Gold Limited (ASX:BRV) (“Big River”), pursuant to which a subsidiary of Aura (“Aura BidCo”) will acquire 100% of the issued and outstanding ordinary shares in the capital of Big River (“Big River Shares”) by way of a scheme of arrangement under Part 5.1 of the Australian Corporations Act 2001 (“Scheme”). Pursuant to the Scheme, holders of Big River Shares (“Big River Shareholders”), other than Dundee Resources Limited (“Dundee Resources”), will receive A$0.36 in cash (“Cash Consideration”) for each Big River Share held. Aura will hold its interest in Aura BidCo through an intermediate holding company (“Aura JVCo”) and Dundee Resources has agreed, subject to certain limited conditions, to receive shares in Aura JVCo (“Share Consideration”), in lieu of the Cash Consideration in order to indirectly maintain an equity interest in Big River (“Transaction”). Unless otherwise stated, all dollar values in this announcement are in Australian dollars.

The acquisition represents an attractive opportunity for Aura to expand its pipeline of development stage projects through the acquisition of Big River’s Borborema Gold Project in Brazil (“Borborema”). Borborema, which is expected to operate an open pit gold project, has a JORC-compliant Measured and Indicated Mineral Resource estimate of 1.87Moz Au at 1.14 g/t Au and an additional Inferred Mineral Resource of 0.57Moz Au at 1.0 g/t Au.3 Aura’s management and skilled personnel have extensive experience in the Brazilian mining industry and are well suited to develop Borborema in partnership with Dundee Resources.

Rodrigo Barbosa, Aura’s President & Chief Executive Officer, commented: “Our strategy is to grow beyond our current production plan through advancing high-quality projects that have a clear path to construction and are located in the Americas, preferably in jurisdictions where we are already operating. Borborema fits well within this strategy. We are also proud to partner with Dundee Resources on this project as they are a leader in the industry.”

Dundee Resources Support

Dundee Resources, which holds 19.3% of all issued Big River Shares, has entered into a binding Cooperation and Commitment Deed with Aura pursuant to which Dundee Resources has agreed to receive the Share Consideration in order to indirectly maintain its equity interest in Big River post-closing. It is expected that, following closing of the Transaction (if certain conditions are satisfied), Dundee Resources will ultimately hold an indirect 20.0% equity interest in Big River through Aura JVCo. In limited circumstances, including where Aura determines to proceed to completion of the Scheme notwithstanding a termination right having arisen under the SID, Dundee Resources may elect to receive the Cash Consideration in lieu of the Share Consideration, with Aura then acquiring 100% of Big River for 100% Cash Consideration.

Key Transaction Terms

The Transaction is subject to certain conditions precedent including, among others:

  • Shareholder approval being obtained from Big River Shareholders in relation to the Scheme;
  • Court and ASIC approval in relation to the Scheme, and ASX waivers and consents to the extent required;
  • Delivery of a report from an independent expert concluding (and continuing to conclude) that the Scheme is in the best interests of Big River Shareholders;
  • No material adverse effect or prescribed event occurring in relation to either Big River;
  • Big River unlisted option holders agreeing to the cancellation of their options; and
  • Big River maintaining a certain minimum cash balance.

Big River’s independent board committee (“Big River IBC”) has unanimously recommended that Big River Shareholders vote in favour of the Scheme, subject to certain standard conditions. The SID also includes certain exclusivity arrangements in respect of the Transaction (including “no shop”, “no talk” and “no due diligence” obligations on Big River, and a “notification” and “matching right” in favour of Aura), as well as a customary break fee payable by Big River to Aura in certain circumstances, and a reverse break fee payable by Aura to Big River in certain circumstances. As Big River is a public company in Australia, the exclusivity arrangements are subject to customary exceptions that enable the Big River IBC and Big River’s directors to comply with their fiduciary and / or statutory duties.

Big River Shareholders will be asked to approve the Scheme at a shareholder meeting which is expected to be held in July 2022, with closing of the Transaction anticipated to be in or around late July or early August 2022.

Aura notes that in Big River’s ASX announcement in connection with the Transaction, Big River details the receipt of a voting intention statement from the Copulos Group (“Copulos”), a 18.8% Big River Shareholder, to the effect that Copulos intends to vote or cause to be voted all of the Big River Shares held by Copulos (directly or indirectly) at the time of the Big River Scheme meeting, in favour of the Scheme resolution, in the absence of a superior proposal and subject to an independent expert opining that the Scheme is in the best interests of Big River Shareholders (with that opinion being maintained up to the date of the Scheme meeting). Refer to the Big River ASX announcement at (under the Big River ASX ticker “BRV”) for further details of the terms of the intentions of Copulos.

The technical information in this press release was reviewed by Mr. Farshid Ghazanfari, a Qualified Person (“QP”) who is a Registered Member of the ‘Professional Geoscientists Ontario’, a ‘Recognized Professional Organization’ (“PGO”). Mr. Ghazanfari is Director of Mineral Resources and Geology and a Qualified Person to Aura.

In this press release, the Company has disclosed resource estimates in respect of Borborema that are not based on Canadian Institute of Mining, Metallurgy and Petroleum (“CIM“) definitions, but instead have been prepared in reliance upon the Australasian Code for Reporting of Exploration Results, Mineral Resources and Ore Reserves (“JORC Code“). Estimates based on the JORC Code are recognized under NI 43-101 in certain circumstances. The Company’s QP confirmed that while the CIM definitions are not identical to those of the JORC Code, the resource and reserve definitions and categories are substantively the same as the CIM definitions mandated in NI 43-101 and will typically result in reporting of substantially similar reserve and resource estimates.
