when Perseus moved to acquire Amara. Located in central Côte d’Ivoire, it has the potential for large-scale, long-life, low cost production. An optimised PFS completed by Amara earlier this year outlined an open-pit mine with an aver- age annual production of 248 000 ounces in years 1-5 and average annual produc- tion of 203 000 ounces over a 15-year life of mine (LOM) from a single open pit containing 3,2 Moz. The average head grade processed would be 1,62 g/t based upon the mineral reserve estimate announced in January this year. The PFS estimated the upfront capital cost at US$334 million, including a US$44 million contingency and US$60 mil- lion for an owner-operated mining fleet. The PFS put the payback period at 2,1 years with mining throughout this period focused on the higher grade, continuous CMA zone where 72 % of Yaouré’s proven mineral reserves are located. Perseus is now starting work on a bankable feasibility study for Yaouré, commencing with a 42 000 m drilling programme designed to

confirm mineral resource estimates as a basis for mine optimisation. It expects to complete the DFS, financing and execution plan within 18-24 months with mine commissioning following roughly within 18 months of a devel- opment decision. 
