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 the first gold poured during the fourth quarter of 2019. The development plan laid out phases of development: Phase 1 – increase plant capacity to 2ktpd. Phase 2 – increase capacity further to 6ktpd. Phase 1 achieved commercial production in October 2020, followed by Phase 2 in October 2022. Phase 3 – refurbising the KMS and BSVS shafts, to support ore production up to 6ktpd, was completed in December 2024. In 2024, the mine produced 221koz of gold.
