What CBG does

Compagnie des Bauxites de Guinée (CBG) is a Guinea-based bauxite mining joint venture founded in 1963, with commercial operations beginning in 1973 from the Sangarédi open-pit mine in the Boké region. The company is owned 49% by the Guinean State and 51% by the Halco Mining consortium (Alcoa, Rio Tinto, Dadco Investments), and operates a vertically integrated value chain spanning open-pit extraction at Sangarédi, 132 km of dedicated railway (the Chemin de Fer de Boké), a crushing and drying plant at Kamsar (reducing moisture to 3%), and a dedicated mineral pier capable of simultaneously loading two 60,000-tonne vessels. Following completion of the approximately $1 billion Extension Project in 2024, CBG's nameplate capacity increased from 13.5 million to 25–28 million tonnes per year, with current production exceeding 17 million tonnes annually.

The company sells high-quality bauxite exclusively to international aluminum smelters and alumina refiners under long-term offtake contracts, generating revenue through commodity transactions priced against international bauxite market indices. Pricing is contract-driven based on alumina content and quality specifications; there is no retail or spot distribution channel. The customer base is a single horizontal segment of major global aluminum producers, with no intermediaries or resellers in the export chain. Approximately 2,300 direct employees (over 95% Guinean nationals) support operations, with medical coverage extended to roughly 15,000 beneficiaries, and women representing 11% of the workforce including 73 in managerial positions.

CBG's operational moat rests on its state-backed concession structure, integrated mine-to-port logistics chain, multi-user railway governance under ANAIM, and adherence to international ESG standards (triple ISO 9001/14001/45001 certification renewed in January 2026 with zero major non-conformities, plus ASI certification). The company has cumulatively contributed over $5.5 billion to the Guinean state since 1973 and maintains active community programs including health centre upgrades (33,000+ beneficiaries at Port-Nènè), environmental rehabilitation (26,000 trees planted, 30,000+ m² restored under the REB network), and passenger rail service via the Kakandé Express. Recent strategic signals — including a stated future refinery ambition presented at the Simandou 2040 Forum — indicate potential downstream vertical integration beyond raw bauxite export.

Revenue model

1. Bauxite Mining and Export: CBG extracts bauxite at Sangarédi, processes it at the Kamsar plant (drying to 3% moisture), and exports it via ship from the Kamsar mineral pier. Revenue is generated through long-term offtake contracts with international aluminum producers. Production capacity exceeds 18.5 million tonnes per year following the extension project completed in 2024.

Core offering

CBG extracts high-quality bauxite from the Sangarédi open-pit mine in the Boké region of Guinea and exports over 17 million tonnes per year through an integrated value chain: 132 km dedicated railway transport to the Kamsar processing plant (crushing, drying to 3% moisture, automated quality sampling), followed by shiploading at the dedicated Kamsar mineral pier capable of handling two 60,000-tonne vessels simultaneously. The company sells under long-term offtake contracts to international aluminum smelters.

Product overview

CBG operates an integrated bauxite mining and export operation with a unified platform spanning four key stages: extraction at the Sangarédi mine, 132 km rail transport via the Chemin de Fer de Boké, processing at the Kamsar plant, and port export at Kamsar. The core product is high-quality bauxite with 17+ million tonnes annual production. This platform is enhanced by two major projects: the Extension Project (Projet d'Extension) that modernized and expanded capacity to 25-28 million tonnes, and the Multi-User Railway Project (Projet Multi-Utilisateurs) enabling shared infrastructure with other mining companies. Support is delivered through dedicated services covering HSE, technical maintenance, strategy, HR, finance, legal, procurement, engineering, and security functions.

Direct peers

• Guinea Alumina Corporation (GAC): GAC is a major Guinean bauxite exporter owned by Emirates Global Aluminium. It co-signs the Multi-User Railway Contract with CBG and shares the same Boké–Kamsar rail and port corridor, making it the closest geographic, logistical, and product analogue to CBG.
• Compagnie de Bauxites de Dian-Dian (COBAD): COBAD is a Guinean bauxite mining joint venture that is also a co-signatory of the 2015 Multi-User Railway Agreement alongside CBG and GAC. It operates in the same Boké region and competes for shared rail capacity on the Boké corridor.
• Société Minière de Boké (SMB): SMB is one of the largest Guinean bauxite producers, shipping tens of millions of tonnes per year through its own and shared port infrastructure. It directly competes with CBG for international aluminum market share out of Boké.
• RUSAL: Russian aluminum major RUSAL is a co-user of the Boké Railway under the Multi-User Project and one of the world's largest integrated bauxite-aluminum producers. It competes in global bauxite markets and overlaps with CBG on logistics infrastructure in Guinea.
• Bosai Minerals Group: Bosai operates the Awaso bauxite mine in Ghana and has been expanding West African bauxite capacity. It is a regionally focused bauxite producer that competes in the same West African corridor of international aluminum supply.

Broad incumbents

• Alcoa: Alcoa is one of the three Halco Mining partners (alongside Rio Tinto and Dadco) and a 51%-consortium shareholder of CBG. As a global integrated aluminum major, Alcoa directly competes in upstream bauxite supply and has deep operational overlap with CBG's value chain.
• Rio Tinto: Rio Tinto is one of the three Halco Mining partners of CBG and runs its own global bauxite business (notably in Australia). As a diversified mining major with significant aluminum exposure, Rio Tinto is a direct competitor in seaborne bauxite markets.
• Emirates Global Aluminium (EGA): EGA is the parent of Guinea Alumina Corporation and one of the largest bauxite-to-aluminum producers outside the China / Russia / North America axis. EGA's vertical integration into alumina refining provides a comparable business model benchmark and a competitor in Guinea.
• South32: South32 operates the Worsley alumina refinery and bauxite mine in Australia and is a significant seaborne bauxite exporter. It competes with CBG for share of international aluminum smelter offtake contracts.
• Norsk Hydro: Norsk Hydro is a global integrated aluminum producer with owned bauxite mining (notably Paragominas in Brazil). Its vertical bauxite-to-aluminum model and seaborne alumina/bauxite supply make it a relevant comparable for CBG's scale and customer base.
