Guinea has reached significant milestones in its industrial and infrastructure sectors under the leadership of President Mamadi Doumbouya. In October 2026, the President inaugurated the Transguinéen (CTG) passenger train, a key component of the Simandou project. This railway is part of a 650 km corridor designed to connect Morébaya to mining blocks in southern Guinea, featuring major engineering works such as the longest railway tunnel in West Africa.

On November 1, 2026, the government inaugurated the Nimba Gold Refinery (NGR) in Gbessia, Conakry. As the nation’s first gold refinery, the facility has an estimated annual capacity of 733 tonnes. Moussa Magassouba, a representative of the refinery, stated that operating at 50 percent capacity could generate an estimated annual financial flow of 4.5 billion US dollars.

The refinery is part of the Simandou 2040 program, which aims to position Guinea as a regional mining hub. To support this industrial shift, the state has introduced requirements for domestic processing. The government plans to have the central bank purchase up to 30 percent of the gold produced by industrial and semi-industrial mining companies in Guinean francs. A 90 day transition period was introduced in July to allow producers to prepare for these new domestic refining requirements. These initiatives represent a strategic effort to transition Guinea from an exporter of raw materials to a hub for local industrial processing and resource value capture.
