Vault Surges Toward Processing Milestone at King of the Hills

Why It Matters

The upgrade positions Vault to capture higher gold output while maintaining low‑cost production, strengthening its competitive edge amid tightening global supply. Enhanced power reliability also reduces exposure to energy disruptions, appealing to investors seeking stable, low‑cost producers.

Key Takeaways

• Stage 1 upgrade lifts capacity to 6 Mtpa.
• Stage 2 aims for 7.5‑8 Mtpa by FY 27.
• Capital intensity $57 per tonne, 50% throughput boost.
• New crusher and conveyor start processing 31 Mar 2026.
• 15 Mt stockpile holds ~180k oz gold, ensuring flexibility.

Pulse Analysis

Vault Minerals’ Stage 1 upgrade at the King of the Hills (KoTH) operation marks a pivotal step for the Australian gold sector. By installing a new primary crusher and linking conveyor, the mine will process its first ore through the upgraded circuit on 31 March 2026, lifting annual throughput to roughly 6 million tonnes. This capacity jump, combined with four extra carbon‑in‑leach tanks and an upgraded regeneration kiln, delivers a 50% increase in processing efficiency while keeping capital intensity at an industry‑leading $57 per tonne.

The strategic addition of two gas‑fired generators, backed by a three‑year gas‑supply contract, mitigates the risk of power shortages that have plagued many mining projects worldwide. Reliable, on‑site power not only safeguards continuous mill feed but also enhances the mine’s environmental profile by reducing reliance on diesel. As global supply chains face volatility, Vault’s ability to maintain uninterrupted operations gives it a competitive advantage and supports steady cash flow in a market where gold prices remain buoyant.

Beyond operational gains, the upgrade bolsters Vault’s balance sheet. With 15 million tonnes of stockpiled ore containing an estimated 180,000 ounces of gold, the company can flexibly respond to market price movements and potential export constraints. The forthcoming Stage 2 expansion, slated for the second half of FY 27, aims to push capacity toward 7.5‑8 million tonnes, further cementing Vault’s position as a low‑cost, high‑throughput gold producer. Investors are likely to view these developments as a catalyst for earnings growth and dividend sustainability.
