Processing route
Process selection and design philosophy
The process selection at Houndé was based on a design philosophy outlined in Section 17.2.1 of the report. The report states that the process flowsheet is described in Section 17.2.2. The plant description covers the Houndé Process Plant as detailed in Section 17.3, with electrical supply addressed in Section 17.4 and control philosophy in Section 17.5.
Metallurgical testing
Section 13 of the report covers mineral processing and metallurgical testing. A metallurgical summary is provided in Section 13.2. Metallurgical sampling is described in Section 13.3, with sampling conducted for various deposit types including Vindaloo, Bouéré, Dohoun, and Kari deposits. Detailed metallurgical testing is reported in Section 13.4, which includes testwork results that underpin the process design assumptions.
Historical operating performance
Section 17.7 of the report presents historical performance data for the Houndé process plant. This section provides actual operating results from the facility. Section 17.8 addresses the metallurgical life of mine plan and associated assumptions used for forward-looking estimates.
