Vault Minerals Limited is an intermediate gold producer engaged in the exploration, development, operation, and sale of gold and gold-copper concentrates primarily in Western Australia and Canada. The company operates through four key segments: Leonora Operations, including the King of the Hills open pit and underground mines and Darlot operations; Mount Monger Gold Operations; Deflector Region, encompassing Deflector and Rothsay operations producing gold bullion and gold-copper concentrate; and Sugar Zone, focused on gold bullion and concentrate production. It maintains a diversified portfolio of producing assets and development projects, targeting gold production with byproduct copper credits, and serves markets through gold bullion and concentrate sales; operations span the Goldfields and Midwest regions of Western Australia and Ontario, Canada.
Founded in 1995 and headquartered in South Perth, Australia, the company, formerly known as Red 5 Limited, changed its name to Vault Minerals Limited in September 2024 following its June 2024 merger with Silver Lake Resources Limited, creating a production-ready intermediate producer with immediate scale, complementary assets, and enhanced financial capacity of approximately $575 million in cash.
Recent developments include an $80 million Stage 1 expansion of the King of the Hills processing plant, approved in early 2025, to increase throughput by 20% from 5 million to 6 million tonnes per annum, with construction starting April 2025 and commissioning in Q4 FY26, alongside a 39% increase in Leonora ore reserves to 2.8 million ounces and plans for a potential Stage 2 upgrade to 7-8 million tonnes capacity; the company also initiated an on-market share buy-back program in August 2025, repurchasing over 2.2 million shares by late November 2025 to optimize capital structure, and proposed a 6.5-for-1 share consolidation for November 2025 approval to streamline its share register and attract institutional investors.
