On 19 June 2026, President Mamadi Doumbouya chaired a strategic meeting in Conakry with industrial, semi-industrial and artisanal gold operators and gold-buying counters, announcing that "l'exportation de l'or brut appartient désormais au passé" — a formal and permanent prohibition on exporting unrefined gold mined in Guinea. All gold must henceforth be refined domestically, primarily via the state-backed Nimba Gold Refinery (Gbessia, Conakry), before any international sale. Operators who continue exporting raw gold risk suspension or revocation of their operating licence and mining convention. The measure extends Guinea's Simandou 2040 local-transformation doctrine — already applied to bauxite and iron ore — to the gold sector for the first time.

On 21 May 2026, the Guinean State and Chalco Guinea Company (a subsidiary of China's Aluminum Corporation of China / Chinalco) signed a supplementary investment agreement for a USD 1.68 billion alumina refinery to be built at the Lisso-Demougala site near Boffa, with official capacity of 1.2 million tonnes per year. Construction was formally launched on 13 June 2026 by Minister of Mines Bouna Sylla alongside the Secretary General of the Presidency and the Chairman of the Simandou 2040 Strategic Committee. The plant is Guinea's third alumina refinery post-independence (after the SPIC Boffa plant and the Winning Consortium facility), deepening Guinea's Simandou 2040 strategy of shifting from raw bauxite export to in-country alumina processing.

Guinea's Conseil National de la Transition (CNT) adopted two laws on March 5, 2026 — Loi-Plan L/2026/004/CNT (2026–2040 development plan) and Loi-Programme L/2026/005/CNT (2026–2030 implementation programme) — constituting the first-ever national-plan legislation to encode the Simandou 2040 economic-transformation agenda into law. President Mamadi Doumbouya promulgated both laws by presidential decree on March 20, 2026. The programme targets average GDP growth of 10.3% per year, a projected GDP of ~$152B by 2040 (vs. ~$35B today), 122 megaprojects, 36 structural reforms, and >5 million new jobs, with iron ore, bauxite-to-aluminium, energy, infrastructure, and agriculture as the six transformation pillars.

On 11 November 2025 President Mamadi Doumbouya officially inaugurated start of operations at the Simandou Integrated Project — Africa's largest greenfield mine-and-infrastructure asset — at a ceremony attended by the presidents of Rwanda and Gabon, China's Vice-Premier, and PMs from Côte d'Ivoire and Sierra Leone. The project comprises Blocks 1–2 (WCS: Winning International / China Hongqiao / Baowu) and Blocks 3–4 (SimFer: Rio Tinto 53% / Chinalco-led JV 47%), connected by 622 km of multi-use trans-Guinean railway to barge and transhipment port facilities at Forécariah, operated by Compagnie du TransGuinéen (CTG). Combined design capacity is up to 120 Mt/yr of high-grade (~65% Fe) iron ore, the largest single addition to seaborne supply since Vale's S11D ramp in 2016, structurally reshaping Australia-Brazil price competition and China's iron-ore import geography.

President Mamadi Doumbouya signed two decrees on 5 August 2025 revoking Guinea Alumina Corporation's (GAC, a subsidiary of UAE's Emirates Global Aluminium) 690.20 km² bauxite mining concession in Boké Prefecture — citing GAC's non-compliance with article 88 of the October 2004 base convention requiring an alumina refinery development plan under the Simandou 2040 processing mandate. The concession was transferred without compensation to newly created 100%-Guinean state entity Nimba Mining Company SA (NMC), which received a 25-year mining title with a one-year deadline to commence operations. All technical reports and geological data (~400 Mt resource) were transferred to the State without indemnification.

Guinea's Council of Ministers activated a longstanding right in the Mining Code on 14 July 2025, mandating that at least 50% of all bauxite export volumes be shipped on Guinean-flag vessels. To operationalise the mandate, the government simultaneously created Guinéenne des Transports Maritimes (GUITRAM), a 100% state-owned maritime company designated as the exclusive Guinean-flag carrier for the mandated share. A complementary Guinea Bauxite Index (GBX) was launched simultaneously to establish a state-managed reference price for export pricing. The measures redirect freight revenues — estimated at $15–25 per tonne — from existing (predominantly Chinese-controlled) shipping operators toward the Guinean state, applied to approximately 130 Mt/year of exports that constitute roughly 60% of global seaborne bauxite supply.

On 26 March 2025 President Mamadi Doumbouya presided over the groundbreaking ceremony for Guinea's first alumina refinery since independence, developed by Chinese state enterprise SPIC International Investment and Development (Guinea) Co. Ltd. in Boffa Prefecture (Koundindhé district). The plant — USD 1.03 billion investment — will process 15 Mt/yr of bauxite into 1.2 Mt/yr of alumina, paired with a 250 MW integrated power plant (100 MW to Guinea's national grid); commercial production is targeted for late 2028. The project operationalises Guinea's Simandou 2040 in-country processing mandate, under which all bauxite concession holders must commit to building alumina refineries or face licence revocation, cementing Chinese-capital control of Guinea's bauxite-to-aluminium value chain.

On 3 February 2024 Guinea's National Transition Council (CNT) ratified three inter-linked conventions structuring the Simandou integrated iron-ore mega-project: (i) the co-development agreement for the 670km Trans-Guinéen rail and Morebaya/Forécariah port, executed via the Compagnie du TransGuinéen (CTG) JV between the Republic of Guinea, Winning Consortium Simandou (WCS) and Rio Tinto Simfer; (ii) the WCS operating framework for blocks 1–2; and (iii) the bilateral adjustments to Simfer's amended-and-consolidated base convention covering blocks 3–4 with Rio Tinto and Chinalco/Baowu participation. Estimated integrated capex USD 15–20bn; first commercial shipment from Forécariah occurred in November 2025 with President Mamadi Doumbouya attending. At full ramp Simandou is designed for ~120 Mt/yr of high-grade (~65% Fe) ore — the largest single addition to seaborne iron-ore supply since Vale's S11D (2016).

Guinea's Minister of Mines and the Minister of Finance and Budget issued a joint ministerial arrêté (approximately July–September 2022, official date recorded as 2022-09-01) establishing a mandatory bauxite reference price mechanism — the first fiscal-transparency instrument requiring all bauxite exporters operating in Guinea to apply a government-set benchmark FOB price on all export transactions. Any declared export price below the reference benchmark triggers an automatic upward adjustment to the benchmark level for purposes of royalty and tax computation, eliminating the transfer-pricing and underpricing loophole that the International Monetary Fund and the Intergovernmental Forum on Mining, Minerals, Metals and Sustainable Development (IGF) estimated caused >$1 billion per year in revenue leakage for the Guinean state. The mechanism operates separately from export quota and cap actions; it functions as a fiscal floor applicable across all operators. Chinese joint-venture operators — which control the majority of Guinea's bauxite production and export volumes — were the primary target given the prevalence of intracompany transfer pricing in Chinese-financed bauxite-to-aluminium supply chains.
