The Guinea gold refinery opened on Sunday 1 November, when President Mamadi Doumbouya inaugurated the country’s first plant that refines gold into bars. The Nimba Gold Refinery stands in Gbessia, a district of the capital Conakry beside the international airport.
For US buyers and investors, it follows Guinea’s ban on raw gold exports, so only bars refined at home may now leave. Our reports on the export ban and the first refined bars show how the rule came about.
In Plain English, Who Is Who
Refining means melting and purifying mined gold into bars of known purity that banks and jewellers will accept. Nimba Gold Refinery (NGR) is the company that runs the new plant.
Bouna Sylla is Guinea’s Minister of Mines and Geology, and Moussa Magassouba spoke for the refinery’s management and staff. Mamadi Doumbouya is the army officer who took power in a 2021 coup and now serves as president.
What Happened at the Opening
Doumbouya inaugurated the plant on Sunday 1 November at the Cité de l’Air site in Gbessia. The authorities present it as the first of a series of refineries, with more expected in the coming months.
Sylla told the ceremony that Guinea has long exported its gold raw and lost the value of refining, and that this era is over. Magassouba said no country can build lasting prosperity by exporting raw materials alone.
How Big Is the Refinery
The company puts the nominal capacity of the Guinea gold refinery at 733 tonnes a year, its limit at full use. Magassouba said that at half capacity it could handle about US$4.5 billion a year, without saying how that was calculated.
For scale, Guinea exported roughly 70 tonnes of gold in 2025, say the mines ministry’s figures. The plant is built to take far more than the country mines, and its management lists partnerships with international gold buyers among its aims.
Why Guinea Wants Its Gold Refined at Home
About 70% of Guinea’s gold still comes from small-scale artisanal miners, Sylla said, and the government wants more from larger, formal mines. Doumbouya announced the end of raw gold exports on Friday 19 June, and a July decree gave operators 90 days to adapt.
The first refined bars left the country on Friday 9 October, as our earlier report describes. It fits a wider push to earn more from mining, covered in our Guinea explainer and our report on Simandou 2040 spending rules.
What the State Will Buy
Under the Mining Code, the state will buy up to 30% of the gold from semi-industrial and industrial companies, paying in Guinean francs. Sylla said this is meant to build up the foreign-currency reserves of the Central Bank of the Republic of Guinea.
He also said three alumina refineries are under construction, as Guinea tries to process more of its bauxite at home. Alumina is the white powder refined from bauxite that is later smelted into aluminium.
What It Means for US Readers
Refined bars are now the only form in which Guinea’s gold may leave the country. US jewellers and funds that must prove their gold’s origin will therefore see Guinean-certified bars.
The Guinea gold refinery does not change world gold prices by itself, because it has yet to show how much it will refine. How much gold the state will buy, and at what price, has not been announced.
What Is Not Known
The government gave no cost for the Guinea gold refinery and did not name its owners or investors. It also gave no number of jobs, only a pledge of lasting skilled work and training for young Guineans.
It is not clear how much gold the plant refined before the opening, or when it will reach its nominal capacity. The company did not say what the US$4.5 billion figure measures.

Frequently Asked Questions
What opened in Guinea on 1 November?
President Mamadi Doumbouya opened the Nimba Gold Refinery in Gbessia, Conakry, the country’s first gold refinery. It is meant to refine Guinea’s gold at home instead of exporting it raw.
How much gold can the refinery handle?
The company says the Guinea gold refinery has a nominal capacity of 733 tonnes a year. Nominal capacity is the maximum at full use, not expected output.
Who owns the Nimba Gold Refinery?
The government did not name the owners or investors at the opening. It also gave no cost for the plant.
Can Guinea still export raw gold?
No. Only gold refined and certified in Guinea may leave the country since the export ban announced on 19 June.
Does this matter to US readers?
Mainly for gold buyers who need proof of origin, and for investors in West African mining. The opening alone does not move world gold prices.
