What did Vault Minerals report?

  • High-grade gold intersections at KoTH, including 7.60 m at 31.7 g/t, 10.25 m at 4.13 g/t, and 1.77 m at 16.5 g/t in the granodiorite host
  • Extensive infill and extensional drilling at Darlot's Pipeline and Warne areas, with results up to 151.5 g/t
  • Deflector's Contact lode returned 1.3 m at 22.8 g/t, 1.3 m at 17.1 g/t, and 0.8 m at 27.6 g/t
  • First assays at Sugar Zone TT8 yielded 1.05 m at 21.2 g/t and 6.29 m at 3.16 g/t, with more results pending
  • Significant resource definition drilling undertaken: 63,378 m at KoTH in FY25 and 26,101 m to date in FY26

What else do investors need to know?

Vault is expanding exploration across its key Western Australian and Canadian assets. At KoTH, drilling has extended mineralisation up to 500 metres beyond current mining areas, highlighting strong potential to grow underground reserves and extend mine life. Darlot's Warne and Pipeline zones have produced encouraging results, presenting new opportunities for near-term production fronts. Meanwhile, at Deflector, recent drilling is establishing the Contact lode as a fresh mining front.

The company is also assessing a potential refurbishment of the Darlot processing facility to strengthen its processing footprint in the gold-rich region. Regional drilling at Deflector and Sugar Zone is ramping up, with substantial untested targets set to be explored through 2026.

What did Vault Minerals management say?

Managing Director Luke Tonkin said:

This outstanding suite of results highlights the opportunity to grow our Mineral Resource base and extend the life of mine across multiple deposits. Our team continues to unlock the potential of our well-established assets in highly prospective regions.

What's next for Vault Minerals?

The company's strategy centres on aggressive exploration to support life of mine extensions and build new mining fronts at KoTH, Darlot, Deflector, and Sugar Zone. Resource definition and step-out drilling will continue throughout FY26, targeting further reserve growth. Vault intends to complete pending assays and progress plans for a potential processing upgrade at Darlot, which could accelerate production from emerging gold zones.

Regional exploration at Deflector's Gullewa trend and Sugar Zone's TT8 prospect is scheduled to ramp up in coming months, aiming to identify additional high-grade targets and support ongoing growth in resource inventory.
