The study incorporates the July 2026 Mineral Resource Estimate of 47.9Mt at 1.0g/t gold equivalent (AuEq) for 1.6Moz AuEq, showing a 39% increase in resource tonnes and a 69% increase in Indicated Resources since the May 2026 Scoping Study. The processing and marketing strategy remains unchanged, with a cyanide-free flotation flowsheet producing a saleable precious metal concentrate. The study is expected to be completed in the December 2026 quarter.
