Loulo-Gounkoto Complex… Q3 update Combined production from Loulo and Gounkoto increased 16% quarter on quarter to 174 018oz due to 21% improvement in grade Total cash cost per ounce of $577/oz was 16% lower on the back of increased gold production Profit from mining increased 19% quarter on quarter to $111.9 million Preliminary economic assessment completed on potential of Loulo 3 expanded open pit and underground project Drilling continues to expand high grade mineralisation in south of the Yalea orebody Exploration on the Gounkoto permit leads to review of the Faraba structure where multiple zones of mineralisation show potential to be extended and combined $1.1 million spent on construction of 10 drinking boreholes for communities, village houses, seeds and fertilizers for local farmers Both mines remain ISO 14001 certified
