Vault Minerals Limited (ASX:VAU) is part of a proposed merger with Genesis Minerals that changes what investors would hold. How does a proposed merger with Genesis Minerals change what investors are really holding in Vault Minerals? The practical answer is that Vault's operating results, which were encouraging in the September 2026 quarter, now sit alongside a scheme of arrangement under which each Vault share is to receive 0.7629 Genesis shares plus 47.5 cents in cash, with completion targeted around late November 2026. If the scheme proceeds, Vault would cease to be a stand-alone listed company, so the transaction matters as much as the quarterly production.

The merger terms

Genesis and Vault then announced a merger valued at about A$5.6 billion for Vault, to be implemented by a scheme of arrangement. On a fully diluted basis, Genesis shareholders would own 59.8 per cent of the enlarged group and Vault shareholders 40.2 per cent. The board would have four Genesis directors and three nominated by Vault.

The combined business is forecast to produce roughly 600,000 to 700,000 ounces of gold a year, all in Western Australia. A scheme booklet has been released, and an independent expert concluded the deal is in the interests of Vault shareholders, in the absence of a superior proposal. Completion is subject to shareholder, court and regulatory approvals.

Vault also paid a break fee of about A$50.7 million to Regis, which shows up in the quarter's cash flow. Underlying free Cash Flow was A$95.7 million before that fee.

The September 2026 quarter

Operationally, Vault produced 76,849 ounces of gold in the quarter and sold 79,085 ounces at an average realised price of A$6,023 per ounce. All-In Sustaining Cost was A$3,529 per ounce. Leonora produced 44,467 ounces at an all-in sustaining cost of A$2,885 per ounce, although the company noted softer underground output because of manning and equipment constraints. Cash and bullion at quarter end was A$886.7 million and the company has no corporate debt.

The difference between the realised price and sustaining cost is large, about A$2,500 per ounce on these averages, which explains why free cash flow stayed encouraging even in a quarter with a one-off payment.

FY27 guidance

For FY27 Vault guides to production of 355,000 to 375,000 ounces at an all-in sustaining cost of A$3,150 to A$3,350 per ounce. FY26 output was reported at 336,540 ounces. The September quarter annualises to about 307,000 ounces, below the guidance range, so, as with many producers, the company is relying on improvement through the year. The cost guidance also sits below the 3,529 achieved in the quarter, which is a further reason to follow the December quarter closely.

Projects underway

Two growth items stand out. The Stage 2 upgrade of the processing plant at King of the Hills was finished ahead of schedule and on budget, with commissioning beginning in October and performance testing planned for late October. Additional throughput at King of the Hills supports the Leonora hub, the area that underpins the merger logic for both companies.

Sugar Zone underground Mining is ramping up, and staffing there increased 87 per cent over the quarter. A fast ramp-up can strain cost control and productivity, so the next quarter's performance there is an important marker.

Sector context

Gold producers have benefited from encouraging prices, as the A$6,023 realised price shows. In the same quarter Perseus Mining reported a realised price of US$3,881 per ounce. Western Australian gold has also seen a wave of consolidation, with larger entities seeking scale, shared infrastructure and bigger resource bases. The Genesis proposal reflects that trend, and the interest from Regis shows Vault was regarded as a valuable asset by more than one bidder.

Risks and things to watch

The main risks fall into three groups. The first is transaction risk: the scheme needs approvals, and it could still Fail or be delayed. The second is operational: underground manning and equipment constraints at Leonora, the Sugar Zone ramp-up and the move from the September run rate to the guidance range. The third is the gold price and Australian dollar, since sustaining costs of about A$3,500 per ounce are lower than the realised price but not immune to cost inflation.

The key dates are the scheme meeting and court approval, expected to lead to implementation around late November, the King of the Hills test results, and the first combined reporting if the merger proceeds. After implementation, investors will be assessing Genesis, with Vault's Assets inside it, so the analysis shifts to the enlarged group's guidance and Capital allocation. Investors who hold Vault should read the scheme booklet and the independent expert's report, because those documents set out the terms, assumptions and conditions in full.
