Ashanti (Obuasi Operations) gold mine project

Report summary

Gold mining and processing in the Ashanti pre-dates the colonisation of Ghana. At its peak in the mid-90s, the mine produced approximately 1Moz/a but due to legacy issues such as ageing infrastructure, production was on a downward trend. In 2014, mining activities ceased and the mine was placed on care and maintenance. In 2017, a feasibility study was completed for a possible re-start of operations at Obuasi. Phase 1 construction (with plant and infrastructure refurbishment) is expected to be completed in 18 months for an initial production rate of 2kt/d. First gold pour is anticipated in Q4 2019. Under plans for Phase 2, major infrastructure works are planned at the underground mine (including shaft and ventilation works), and installation of a primary crusher, SAG and ball mills, and a carbon regeneration circuit at the processing plant over a 12 month period. In the first 10 years of operation, gold production at Obuasi is expected to average between 350 - 450koz/a.
