St Barbara recently announced results of the Simberi Expansion outlining the mining of multiple open pits to exploit the 2.8 Moz oxide and sulphide Ore Reserves. Average annual gold production rises from 65,000 to 75,000 ounces in FY25 to over 200,000 ounces per annum from FY28 through to FY34, with All-in Sustaining Costs between US$1,000 and US$1,200 per ounce.

The final investment decision is expected in late calendar 2025, with first production from sulphide ore in late calendar 2027.

In Nova Scotia, the Touquoy open pit mine (operating since 2017) moved to closure and care and maintenance in September 2023. The Company has three additional advanced stage gold projects (15-Mile, Beaver Dam and Cochrane Hill). The 15-Mile project (with additional ore from Beaver Dam) is being planned as the next operation, with relocation of the Touquoy processing plant to 15-Mile to produce ~70kozpa over an 11 year mine life.

The Company is well capitalised to deliver the next development milestones with ~A$216 million of cash (including A$45 million restricted) and liquid investments of ~A$25 million.
