Vault Minerals Limited operates gold mining assets across Western Australia and is progressing the restart of the Sugar Zone operation in Ontario, Canada. Its September 2026 quarterly report detailed production, cash generation and commissioning activity at the King of the Hills processing facility, while a proposed combination with Genesis Minerals remains under consideration. On 28 October 2026, Vault Minerals (ASX:VAU) shares were quoted at AUD 5.55, up 2.97% during the session. Key measures ahead include plant performance and FY27 guidance.

Company Business

Vault Minerals (ASX:VAU) operates the Leonora, Mount Monger and Deflector mining centres in Western Australia. Leonora includes the King of the Hills open-pit and underground operations, the Darlot underground mine and processing infrastructure. Mount Monger comprises mining assets near Kalgoorlie, while Deflector produces gold and associated copper in Western Australia’s Mid West. Its Canadian Sugar Zone project adds an underground development and restart program to the portfolio.

Output depends on ore grades, plant throughput, recovery rates and workforce availability.

Recent Development

In its 22 October 2026 quarterly activities report, Vault Minerals (ASX:VAU) reported 76,849 ounces of gold produced and 79,085 ounces sold in the three months to 30 September. The average realised gold price was AUD 6,023 per ounce and group all-in sustaining costs (AISC) were AUD 3,529 per ounce. Leonora contributed 44,467 ounces, Mount Monger 15,320 ounces and the Deflector region 17,062 ounces. Deflector also produced 76 tonnes of copper.

The stage-two King of the Hills processing upgrade was completed ahead of schedule and within budget, with performance testing scheduled for late October. The company also reported that underground development at Sugar Zone had recommenced in July. Staffing and equipment constraints affected the initial pace of underground operations, making the subsequent ramp-up a measurable operating issue.

A proposed scheme of arrangement with Genesis Minerals is scheduled for implementation in late November 2026, subject to the required approvals and other conditions. Vault had previously terminated a proposed transaction with Regis Resources. The earlier termination also involved a disclosed break fee.

Financial Performance and Sector Context

Vault Minerals (ASX:VAU) generated underlying free cash flow of AUD 95.7mn in the September quarter before paying a AUD 50.7mn break fee associated with the terminated Regis transaction. Cash and bullion stood at AUD 886.7mn at 30 September 2026. The company reported no corporate debt and no outstanding gold hedges, leaving realised revenue more directly exposed to prevailing bullion prices.

For FY26, Vault reported gold production of 336,540 ounces and sales of 334,904 ounces. Revenue from metal sales was AUD 1,880.2mn, up 31% on the previous comparable period, while underlying EBITDA rose 54% to AUD 953.3mn. Underlying profit before tax reached AUD 619.1mn and statutory net profit after tax was AUD 278.4mn. Underlying annual free cash flow totalled AUD 487.8mn.

Standalone FY27 guidance remains 355,000–375,000 ounces of gold at AISC of AUD 3,150–3,350 per ounce. September AISC exceeded the full-year guidance range, making subsequent costs important to monitor.

Risks to Consider

Vault Minerals (ASX:VAU) faces processing commissioning, underground mine ramp-up and workforce availability risks. The proposed Genesis scheme remains conditional, with timing and transaction execution still relevant. Cash flows are exposed to gold price movements, operating costs and capital expenditure.

What to Watch Next

Upcoming disclosures may clarify King of the Hills throughput, Sugar Zone productivity and quarterly costs. The scheme meeting, approvals and late-November timetable also remain relevant to the proposed transaction.

Key Insights

Vault Minerals (ASX:VAU) entered FY27 with 76,849 ounces of quarterly production, AUD 886.7mn in cash and bullion, and work continuing on processing and underground development. Standalone guidance remains unchanged, with commissioning, costs and the merger timetable central to subsequent updates.
