OPERATIONS

Production, Costs and Notional Cashflow

Perseus’s three operating gold mines, Yaouré and Sissingué in Côte d’Ivoire, and Edikan in Ghana, demonstrated strong performance in Q3 FY26 producing a combined total of 107,144 ounces of gold, 21% more than the 88,888 ounces achieved in Q2 FY26. Higher production was achieved across all three operating gold mines.

The weighted average production cost was US$1,238 per ounce, while the weighted average All-in-Site Cost (AISC) was US$1,748 per ounce. The weighted average AISC for the quarter was lower than the Q2 FY26 AISC of US$1,800 attributable to higher production.

Gold sales from all three operations totalled 96,260 ounces or 9,653 ounces more than in Q2 FY26 attributable to higher production. The weighted average realised gold price was US$4,143 per ounce, US$706 per ounce more than the Q2 FY26 price of US$3,437 per ounce.

Perseus’s average cash margin for the quarter was US$2,395 per ounce, resulting in notional operating cashflow of US$252 million from all operations. This was US$107 million higher than in Q2 FY26.

FUEL SUPPLY CONDITIONS AND OPERATIONAL IMPACT

The Group continues to closely monitor fuel supply availability, consumption levels and inventory positions to mitigate the risk of operational disruption in the short to medium term.

Perseus is working with its long-standing fuel suppliers in the region to assess any material impacts of the current Iran conflict. There were no operational disruptions to the Group’s activities during Q3 FY26, and fuel supply is expected to be sufficient to support operations. Refer to the “Group Gold Production and Cost Guidance” section for the sensitivities of diesel price to AISC.
