Guinea Explained: Doumbouya’s Rule, Bauxite, Simandou Iron Ore and What to Watch

GUIDES · GUINEA

Guinea explained for readers far from West Africa. This small, poor country supplies much of the world’s aluminium ore and has just opened a giant iron-ore mine. Here is who runs it, how its economy works and what to watch.

Guinea sits on the raw materials behind two of the world’s most used metals, aluminium and steel. The soldier who took power in 2021 is now its elected president. The money from those minerals is only starting to arrive.

What kind of country is this?

Guinea, often called Guinea-Conakry to tell it apart from its neighbour Guinea-Bissau, lies on the Atlantic bulge of West Africa. It borders Guinea-Bissau, Senegal, Mali, Côte d’Ivoire, Liberia and Sierra Leone. It is about the size of the United Kingdom.

The country falls into four natural regions. Lower Guinea is the humid coast around Conakry. Middle Guinea is the Fouta Djallon plateau, where the Niger, Senegal and Gambia rivers rise. Upper Guinea is savannah, and Forest Guinea is the wet south-east near Liberia.

That geography matters for business. Most bauxite lies in the west, near the port town of Kamsar and the Boké region. Simandou, the great iron-ore range, sits deep in the south-east, far from any port. Getting ore to the sea has always been the problem.

Guinea was a French colony until 2 October 1958. It was the only French territory to vote against staying in a French-led community that year, and it left at once. Its first president, Sékou Touré, ruled until his death in 1984.

Soldiers then took over under Lansana Conté, who governed until he died in 2008. A new junta ruled briefly before Alpha Condé won the 2010 election, the first widely seen as competitive. Guinea’s history since independence has swung between strongmen and short democratic openings.

Who runs Guinea and how

Power sits with Mamadi Doumbouya, a former special forces commander. On 5 September 2021 his unit removed Alpha Condé, who had changed the constitution in 2020 to run for a third term. Doumbouya promised a return to civilian rule.

That return came on his terms. A new constitution passed in a referendum on 21 September 2025 with about 89 percent of the vote. It lengthened the presidential term from five to seven years, with a limit of two terms. It also let the junta leader stand for office.

The presidential election followed on 28 December 2025. Doumbouya won 86.72 percent, and the Supreme Court confirmed the result on 4 January 2026. The exiled opposition leader Cellou Dalein Diallo had called for a boycott. Doumbouya was sworn in on 17 January 2026.

Legislative and local elections were held on Sunday 31 May 2026. The main opposition parties could not take part. Authorities had dissolved the parties of Condé, Diallo and former prime minister Sidya Touré, plus 37 others. They cited failures such as unfiled financial statements.

Provisional results came on 5 June, Reuters reported. The pro-Doumbouya Generation for Modernity and Development (GMD) and its allies won at least 100 of the 147 seats. Turnout was 52.87 percent, well below the presidential vote.

Day-to-day government is led by Prime Minister Amadou Oury Bah, known as Bah Oury. Doumbouya reappointed him in January 2026 and kept him in a late-July reshuffle that produced a 31-member cabinet. Bouna Sylla is mines minister and Mariama Ciré Sylla runs the economy and finance ministry.

The new constitution also creates a Senate. Two-thirds of its members are to be indirectly elected and one-third appointed by the president. In practice, the presidency, the army and the mining file remain the centre of power.

How the economy works

Guinea’s economy produced about US$28.3 billion in 2025, according to World Bank data. That is roughly US$1,880 per person, which places Guinea among the world’s poorer countries. Most people still live from farming, trade and informal work.

The export economy, however, is almost entirely mining. Guinea is the world’s largest exporter of bauxite. Bauxite is refined into alumina and then smelted into aluminium, the metal in cars, cans, cables and aircraft.

Shipments reached a record 182.8 million tonnes in 2025, up 25 percent, according to mines ministry data reported by Reuters. China took about three-quarters. In the first half of 2026 exports rose another 15 percent, to 114.8 million tonnes.

The biggest shippers include Chinese group Chalco, Société Minière de Boké (SMB) and Compagnie des Bauxites de Guinée (CBG). The state holds 49 percent of CBG. Gold is the other large mineral export, much of it from Upper Guinea.

Simandou, the iron-ore prize

Simandou is a mountain range holding some of the world’s richest untapped iron ore. It lay idle for decades because it needed a railway of more than 600 kilometres and a new deep-water port. Chinese partners finally helped fund both.

The deposit is split into four blocks. Two belong to Winning Consortium Simandou, a Chinese-led group. The other two belong to SimFer, in which Rio Tinto holds 53 percent and a Chinalco-led consortium 47 percent. The Guinean state holds 15 percent of the operating companies and of the railway.

The first cargo, about 200,000 tonnes, left the coast on 2 December 2025 bound for China, Caixin reported. The partners plan to export up to 120 million tonnes a year. Rio Tinto’s chief executive has said the project should reach full capacity around mid-2028.

The government has wrapped the project in a national plan called Simandou 2040. It is meant to turn ore revenue into roads, power, schools and jobs. On 3 September 2026 Doumbouya set five binding rules for its spending. They include monthly dashboards and a ban on contracts awarded outside procedure.

The push to refine at home

Doumbouya’s central economic demand is local processing. Guinea exports raw ore cheaply and earns little from the refining that happens abroad. Officials want miners to build alumina refineries in the country, even though refineries need large, reliable power supplies that Guinea lacks.

The government has backed that demand with pressure. In 2025 it withdrew a wave of mining permits. The best-known case is Guinea Alumina Corporation, owned by Emirates Global Aluminium. Its exports were halted in 2024 and its assets passed to the state-backed Nimba Mining Company in August 2025.

The same logic now covers gold. In June 2026 Doumbouya banned exports of unrefined gold, saying the metal must be refined in Guinea first.

Emirates Global Aluminium wrote off the business, a charge of about US$680 million. A settlement announced on 6 May 2026 provides for Guinea to pay the company a lump sum. The amount was not disclosed.

Public finances are thin despite the boom. In August 2026 IMF staff reached a preliminary deal on a 41-month loan of about US$425 million. The IMF projects growth of 8.6 percent in 2026, driven by Simandou, and asks for better tax collection and spending control.

What is happening right now

As of 25 September 2026, Guinea is in the first year of an elected government built on the junta. The president, the prime minister and a large pro-government majority in parliament are all in place. The organised opposition is outside the system.

Media freedom is under strain. On 17 September the authorities suspended the French broadcaster France 24 after it described Doumbouya as a “putschist president”. A press-freedom watchdog has asked Guinea to lift the suspension.

The mining story is moving faster than the politics. SimFer began switching on its own Morebaya port in September, Rio Tinto’s venture said. Full commissioning is expected in the first quarter of 2027. Until then its ore leaves through the rival consortium’s port.

On 21 September US locomotive maker Wabtec announced a service contract worth more than US$700 million with the Simandou railway operator. It is the company’s largest services deal in Africa. Foreign partners are also courting Conakry. Rusal, the Russian aluminium group, met the president in September, and Morocco signed 25 cooperation agreements.

The IMF loan still needs approval from the Fund’s Executive Board, which was expected to consider it in September 2026. Bauxite exports remain near record highs. The government has discussed limiting them to support prices, but had not done so by late July, Reuters reported.

What to watch

The IMF board vote. Approval would unlock the first loan payment and give the programme’s targets force. Watch for the fiscal promises Guinea makes, especially on mining revenue and public spending.

Simandou’s ramp-up. The key markers are Morebaya’s full commissioning, due in the first quarter of 2027, and full capacity around mid-2028. Chinese iron-ore import data will show how quickly the new supply reaches steel mills.

Bauxite policy. Quarterly export figures from the mines ministry show whether growth continues. Any export cap, new licence withdrawal or refinery deadline would move global alumina prices.

Political space. Watch whether the Senate is formed, whether dissolved parties are allowed back, and how the new assembly treats mining contracts. Guinea marks its independence day on Friday 2 October.

What this means for foreigners

For investors, Guinea is a mining story with political risk attached. The resources are world-class and the state wants partners. It has also shown that it will revoke permits it thinks are not being used. Contracts depend heavily on relations with the presidency.

For aluminium and steel buyers, Guinea matters well beyond its size. It supplies a large share of the bauxite that feeds China’s alumina industry. Simandou adds a large new source of high-grade iron ore to a market long dominated by Australia and Brazil.

For travellers, the US State Department rates Guinea at Level 2, “exercise increased caution”, citing crime, unrest and weak health services. Visitors need a visa, applied for online, and proof of yellow fever vaccination. Travellers may take no more than 1,000,000 Guinean francs (about US$114) out of the country.

French is the working language of business and government. English is limited outside mining companies and embassies. Visitors should plan to carry cash in Guinean francs for everyday costs.

What Is Not Known

How much Simandou will pay the state. The tax, royalty and dividend terms have not been published in full, and the ramp-up schedule sets the timing. Guinea’s 15 percent stake will only pay out once the project turns a profit.

When the Senate will sit, and whether the dissolved opposition parties will be allowed to return. A full, final seat breakdown by party for the May assembly vote was not available in the sources consulted.

The size of the settlement with Emirates Global Aluminium is unknown. So is whether the Nimba Mining Company can run the former GAC mine at the same scale. Whether the IMF board approved the loan in September had not been announced by the date of this guide.
