Guinea's Gold Export Ban Bet Could Backfire

Guinea, which holds significant gold reserves and is one of West Africa’s emerging gold producers, has imposed a full ban on unrefined gold exports as of June 2026. The ban, aims to encourage local value addition and increase government revenue.

Guinea has substantial gold reserves, estimated at over 1,000 tonnes (some industry reports put proven and probable reserves closer to 1,200–1,500 tonnes. This places Guinea among the top gold jurisdictions in West Africa, with significant untapped potential, particularly in the Siguiri, Kouroussa, and Mandiana regions.

Annual Foreign Income from Gold Exports (Pre-Ban)

Before the June 2026 ban on unrefined gold exports, the state had annual gold production of approximately 600,000 – 750,000 ounces (roughly 18–23 tonnes) in recent years.

Export Revenue is now also at risk with gold exports being Guinea’s second-largest source of foreign exchange after bauxite, with annual earnings from gold exports ranging between $1.2 billion and $1.8 billion in recent years (2023–2025 average). In peak years, gold contributed around 25–30% of total mining export revenue.

The new ban aims to shift more of this value-addition onshore, but it also risks short-term revenue disruption and foreign currency inflows until local refining capacity is built.

Risk to Economy – High Short to Medium Term

Guinea currently has no operational industrial-scale gold refineries capable of producing 99.99% (four nines) pure gold bars that meet LBMA or international marketable standards. All major gold producers in the country such as Siguiri, Lefa, Kouroussa Gold Project, export gold in the form of doré bars (typically 80-95% purity) for refining abroad, predominantly in the UAE (Dubai), Switzerland, and South Africa.

Mining companies acknowledge the policy’s long-term goal but are pushing for a phased rollout of 12–24 months, and for government support for refinery development. Analysts expect negotiations between the government and operators to continue in the coming weeks.

Smaller operators in particular are likely to be hardest hit as they lack the financial backing to maintain production while refining capacity is being addressed. Many are seeking exemptions or joint ventures with foreign refiners. Some mining opperators have temporarily scaled back operations. The alternative is that they would have to cease production – risking the loss of their licences. Industry experts note that building compliant refineries will take time and significant investment. No major independent or foreign-owned refinery project has been completed yet.

Planned Gold Refinery Projects in Guinea (as of June 2026)

There are several planned refineries, however these are still mostly in the planning stage.

1. Guinea Gold Refinery Project (Government-led)
   • Location: Conakry area
   • Capacity: Planned for up to 100 tonnes per year (initial phase)
   • Status: Early development stage. Government seeking international partners.
   • Goal: Meet LBMA standards for refined gold bars.
2. Mano River Resources / Private Consortium Project
   • Foreign-backed initiative involving Chinese and Middle Eastern investors.
   • Planned capacity: 50–80 tonnes per year.
   • Status: Feasibility studies completed; awaiting final approvals and funding.
3. Siguiri Area Refinery (AngloGold Ashanti linked)
   • Proposed by one of the major miners to support local value addition.
   • Status: Discussions ongoing; not yet under construction.

While the new export ban is intended to accelerate these developments, estimates are it will take 18–36 months before any large-scale, LBMA-compliant refinery becomes operational. Challenges include high capital costs, technical expertise, and reliable power supply.

The added risk is that the three planned refineries could require 35–55 MW of reliable power once fully operational. This additional demand represents a significant portion of Guinea’s current power gap. Without major new generation projects (e.g., new hydro or solar), the refineries may face reliability issues or force the government to prioritise power allocation creating even more uncertainty in the gold production sector.
