Guinea has exported its first refined gold, bars made by the Nimba Gold Refinery that left the country on Friday 9 October. The West African mining nation announced a ban on raw gold exports in June, and only metal refined at home may now go abroad.
For US investors and gold buyers, the shipment tests whether Guinea can keep more of its mineral wealth at home. VisionGuinee, a Conakry news site, reported the export on Sunday 11 October, citing the presidency’s press office.
What Guinean Officials Said About the Shipment
Three officials described the shipment, according to VisionGuinee. Ibrahima Sory Conté heads the national office that assays and certifies diamonds, gold and other precious materials.
“Today, we are taking a historic step in the development of our country’s gold sector,” Conté said in French. He added that every gram of gold must be identified, checked and documented before it leaves Guinea.
Mamadou Sylla directs precious materials at the Central Bank of the Republic of Guinea, the country’s central bank. He said the bank certifies exported gold together with the assay office and customs.
“Every gram of gold exported must now be exclusively refined, no more raw gold,” Sylla said. He tied the new export procedure to a presidential decree.
How Guinea Banned Raw Gold Exports
The shipment follows a decision President Mamadi Doumbouya announced on Friday 19 June, at a meeting with industrial and small-scale gold miners and gold buyers. He declared the end of raw gold exports, the Guinean outlet Guinéenews reported on Saturday 20 June.
Doumbouya, an army officer, seized power in a September 2021 coup and won the presidential election of 28 December 2025. Guinéenews named the plant behind his policy as the Nimba Gold Refinery, in Gbessia, the Conakry district around the international airport.
The state news agency, Agence Guinéenne de Presse, said the president wanted local refining to speed up the country’s industrialisation.
On Wednesday 24 June, Foreign Minister Morissanda Kouyaté told diplomats in Conakry that the ban does not stop the sale of gold refined in Guinea. The refinery is not state-owned but “a private investment,” he said, Africaguinee reported.
A decree read on national television on Friday 3 July gave operators 90 days to adjust, Guinéenews reported. After that, only refined gold in bar form, certified by an approved refinery and carrying a certificate of origin, may be exported.
The first exported bars show the new refining chain at work, nearly four months after the raw gold export ban was announced.

Why the Refinery’s Size Stands Out
Moussa Magassouba, a former Guinean minister of mines and now an official at the refinery, gave its size. “The refinery has a nominal capacity of 733 tonnes a year,” he said.
He said the plant would process gold mined in Guinea and gold from neighbouring countries. Nominal capacity is what a plant can handle at full use, not what it actually refines.
That is more than ten times Guinea’s own output. The country produced over 2.2 million ounces of gold in 2025, about 68 tonnes, according to a Ministry of Mines text carried by Africaguinee.
In June, the presidency put the plant’s throughput at 2,000 kilograms of gold a day, rising to 4,000 kilograms with round-the-clock work.
On Saturday 10 October, Ethiopia opened a precious metals refinery rated at more than 600 tonnes a year. Neighbouring Mali began building a refinery in Bamako with a Russian partner in June 2025, Forbes Afrique reported in July.
What It Means for US Readers
Guinea’s gold now leaves only as refined gold bars, so buyers abroad depend on Guinean certificates to know where it came from. That matters to US investors, jewellers and funds that must show their gold is not tied to conflict or smuggling.
Guinea is also a major source of bauxite, the ore used to make aluminium, and is home to the Simandou iron ore project. Its push to process more minerals at home is a signal for every US company that buys or mines there.
For mining companies in Guinea, the rule means their gold must pass through a local refinery before export. Officials have not said how the change affects their costs or contracts.
Gold miners also face new money rules. On 1 October, Mines Minister Bouna Sylla told gold miners the central bank will buy up to 30% of their output in Guinean francs.
He also reminded them they must bring home at least 50% of export earnings, a share the government may raise to 60% to 70%.
What Is Not Known
Officials gave no weight, value or purity for the first shipment of refined gold. They also did not name the buyer or the country where the bars were sent.
Officials have not named the private investors behind the Nimba Gold Refinery or said how much they spent. Nor has the refinery said whether it will seek accreditation from the London Bullion Market Association, which sets standards for bars traded in London.
It is also unclear how much gold the refinery will receive. A capacity of 733 tonnes a year means little until officials publish how much refined gold actually leaves Guinea.
A technical commission of the ministry, the central bank and the mining companies is still setting the terms of the bank’s gold purchases.

Frequently Asked Questions
What did Guinea export on 9 October?
The first gold bars refined inside Guinea, made by the Nimba Gold Refinery. The presidency’s press office announced the export, which VisionGuinee reported on 11 October.
Can Guinea still export raw gold?
No. President Mamadi Doumbouya announced the ban in June, and a July decree set a 90-day transition. Only gold refined in Guinea may now be exported, after checks by the central bank, the assay office and customs.
How big is the Nimba Gold Refinery?
A refinery official, former mines minister Moussa Magassouba, said its nominal capacity is 733 tonnes of gold a year. He said it would also process gold from neighbouring countries.
How much refined gold was in the first shipment?
Officials did not say. They gave no weight, value, buyer or destination for the first export.
Why does this matter to US investors?
Guinea is a large mineral producer, and its refined gold now reaches world markets only with Guinean certificates of origin. Buyers who must trace their gold will rely on those checks.
