90% owned by Perseus

Yaouré Gold Mine, in central Côte d’Ivoire, poured first gold in December 2020, becoming Perseus’s third operation. Perseus declared Commercial Production at Yaouré at the end of the March 2021 Quarter.

Yaouré is expected to produce more than 200,000oz gold per year over the first five years of its mine life at an average AISC of around US$734.

Perseus has identified a number of highly encouraging nearby exploration targets that will be followed up in coming periods with the expectation of delineating sufficient addition mineable Resources to materially extend the current 8.5 year mine life of Yaouré.

Following the granting of an Exploitation Permit and negotiation of a Mining Convention with the government of Côte d’Ivoire, development of Yaouré started in May 2019, using the same combination of development teams (Perseus and Lycopodium) that delivered Sissingué ahead of time and on budget. Development was funded through a combination of existing cash, corporate debt and cash flow from the Edikan and Sissingué operations and progressed on time and on budget allowing Perseus achieved a stretch target of pouring first gold at Yaouré in December 2020 and commenced commercial production in March 2021.

Geology

Yaouré lies within the eastern half of the informally named Bouflé greenstone belt in central Côte d’Ivoire. The belt is a north-north-east-trending assemblage of Palaeoproterozoic volcanic, sedimentary and intrusive rocks of the Birimian Supergroup.

Gold mineralisation at the Yaouré has been subdivided into two main zones: the CMA Zone and the Yaouré Zone.

The CMA zone is a relatively continuous 20-45m thick fault zone featuring quartz-carbonate (dominantly ankerite) veining and disseminated pyrite in albite-carbonate altered metabasalt wall rocks. It strikes approximately north-south, dips at 30 degrees to the east, extends along 1,200 metres strike and its down-dip continuity has been tested for in excess of 450m.

The Yaouré Zone comprises a system of structures in a 300m wide zone, 200m stratigraphically below the CMA Zone and beneath the Yaouré Cen-tral Pit. Gold mineralisation is hosted by a series of brittle-ductile structures divided for convenience into ‘Y’ and ‘S’ types. The ‘Y’ fault zones, parallel to CMA, consist of Y1, Y2 and Y3 – shallow easterly dipping reverse faults with associated albite, carbonate and quartz veins in variably altered host rocks with disseminated pyrite. The ‘S’ type structures comprise sub-vertical faults filled with quartz-tourmaline veins. The ‘S’ type structures are oriented southwest-northeast and northeast-southwest. Mineralisation in the Yaouré Zone is hosted by metabasalts and by a north-south trending granodiorite intrusive body.

Yaouré Production Process

Workforce & Community

We employ more than 1,000 employees and contractors at Yaouré Gold Mine. Around 90% of our workforce are Ivorian nationals and 40% are drawn from the villages nearest the mine.

Perseus is implementing a similar community engagement model at Yaouré to that successfully employed at Sissingué. As the mine moves into operation, community consultation and skills assessments will be undertaken and training and employment committees established. As required under Ivorian law, 0.5% of the revenue generated by Yaouré will be paid into a Community Development Fund, from which a range of community determined, infrastructure and livelihood development projects will be funded.
