On November 1 local time, Guinean President Mamadi Doumbouya presided over the official commissioning ceremony of the Nimba Gold Refinery at the Aviation City in Gbessia, Conakry. This is the first modern gold refinery built in Guinea and a flagship industrial project under the country’s push for local downstream processing and the Simandou 2040 national development plan.
The facility is a gold refinery, handling local smelting, refining and certification prior to export, which is distinct from gold mining or increasing mine output. Initial daily throughput stands at 2,000 kg of gold, rising to 4,000 kg once 24-hour continuous operations are achieved. At full capacity, annual processing capability reaches approximately 733 tonnes, significantly exceeding Guinea’s current production scale. In 2025, Guinea’s gold production was about 69.3 tonnes, with total gold exports across all entities reaching around 72.8 tonnes.
Historically, most gold mined in Guinea has been exported as doré bars, with limited local value addition. The Nimba Gold Refinery provides key infrastructure for Guinea’s “local doré refining” policy. Under regulations issued in June 2026, gold must in principle be refined and certified domestically before export; the transition period for the raw gold export ban ended in early October. Officials stated that local refining marks only the beginning of broader efforts to develop the gold value chain, with further work planned on processing, certification and export systems.
According to Guinean state media, the facility targets 99.99% purity gold bars, and the first batch of locally refined gold was exported on October 9. The national integrated gold traceability platform, PINTO, has been activated, assigning a unique identifier to each batch to track flows from mining to export. Local refining and batch traceability are two separate components of gold sector governance.
At the event, Minister of Mines and Geology Bouna Sylla said local refining would help retain more resource value domestically and stressed the need for stronger sector governance and gold source traceability. Reports also indicated that the government plans to purchase up to 30% of gold production from industrial and semi-industrial miners in Guinean francs to bolster central bank foreign exchange reserves; implementation details remain to be clarified.
The refinery’s impact extends beyond added capacity. If supporting services such as assaying, transport, insurance, warehousing and financial settlement develop in tandem, new service-sector demand could emerge. For companies considering investment in Guinea, the linkage between upstream mineral resources and downstream processing capacity is becoming an important window into changes in the local business environment.
