Gold M&A: Regis, Vault merge to create $7.7B producer

Regis Resources (ASX: RRL) has agreed to merge with Vault Minerals (ASX: VAU) in an all-share deal valued at about A$10.7 billion (US$7.7 billion), creating a new senior gold producer expected to turn out more than 700,000 oz. annually from assets across Australia and Canada.

Regis will offer 0.6947 of its shares for each Vault share, implying a value of about A$5.15 billion and an 11% premium to Vault’s last close. Upon completion, Regis shareholders will own about 51% of the combined company and Vault investors the remaining 49%, with both boards unanimously recommending the transaction.

“This merger creates Australia’s third largest primary ASX-listed gold producer, which demands global recognition,” Regis CEO Jim Beyer said in a release on Tuesday. “With a strong balance sheet, approximately A$1.9 billion in cash and bullion, and a compelling organic growth pipeline, including the McPhillamys development project and Sugar Zone, the combined company is exceptionally well-positioned.”

The deal reflects a broader push towards consolidation in the gold sector, as mid-tier producers seek greater scale, improved liquidity and access to lower-cost capital. The merged group is expected to generate about A$1.7 billion in annualized free cash flow and benefit from more than A$500 million in corporate tax synergies, while maintaining a debt-free balance sheet with roughly A$1.9 billion in cash and bullion.

Duketon complex

Shares in Regis Resources fell 5.9% to close at A$6.75 apiece on Tuesday in Sydney, valuing the company at A$5.11 billion. Vault Minerals stock gained 3.1% to A$4.64 each for a market capitalization of A$4.8 billion.

The portfolio spans multiple operating hubs, including Regis’s Duketon complex in Western Australia, which hosts 38 million tonnes grading 1.1 grams gold per tonne for 1.39 million oz. contained metal, and its 30%-owned Tropicana joint venture, which holds 12 million tonnes grading 1.5 grams for 576,000 ounces.

On a pro forma basis, the combined company would host 6 million oz. in ore reserves and 20.5 million oz. in mineral resources, underpinning long-life operations and future growth.

Vault contributes its cornerstone Leonora hub in Western Australia, which hosts 131.3 million tonnes grading 0.7 gram gold per tonne for 2.79 million oz. in reserves, alongside the Mount Monger and Deflector operations.

The company also brings the Sugar Zone project in Ontario, where reserves total 2.3 million tonnes grading 5.4 grams for 389,000 ounces. It plans to restart production by fiscal 2028 pending permitting for a new tailings facility.

McPhillamys project

Beyond its operating base, the merged group would also control advanced-stage development projects, including the McPhillamys open-pit project in New South Wales It hosts 78 million tonnes grading 1.1 grams gold per tonne for 2.66 million oz. in resources, and offers potential to become a new production hub.

The companies said the combination would deliver a diversified production base across underground and open-pit mines, supported by extensive processing infrastructure with more than 22 million tonnes per year of milling capacity across nine plants, rising to about 24 million tonnes following expansions at Leonora.

The enlarged group will retain the Regis name, remain headquartered in Perth and trade on the ASX. Regis’ Beyer will lead the company, with Russell Clark as non-executive chair, and the board split evenly between directors from both companies.

The transaction will be implemented through a scheme of arrangement and is expected to close in August or September, subject to shareholder, court and regulatory approvals, as well as an independent expert concluding the deal is in the best interests of Vault shareholders.
