Ashanti (Obuasi Operations) gold mine

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, with a mine life of 21 years. In 2018, board approval was received, and the redevelopment project commenced in late 2018, with first gold poured during the fourth quarter of 2019. The development plan laid out two phases of development; Phase 1 – 2,000tpd operation and Phase 2 – 4,000tpd operation. Commercial production was achieved for Phase 1 in October 2020. The operation is expected to ramp up further to 5,000 tpd over the following three years after reaching 4,000 tpd.
