Barrick Gold Cuts 2026 Production Guidance After Flooding Shuts Key Mali Operations
May 26, 2026 — Barrick Gold Corporation has lowered its full-year 2026 gold production guidance after prolonged seasonal flooding forced a suspension of mining and processing activities at the Loulo-Gounkoto complex in southwestern Mali. The pause, which began in mid-May and is now entering its second week with no firm restart date, is expected to remove between 55,000 and 70,000 ounces of attributable gold output from the company's annual tally — a reduction of roughly 3 to 4 percent against prior guidance of approximately 1.85 million ounces.
Loulo-Gounkoto is one of Barrick's flagship African assets. The complex produced more than 500,000 ounces in 2025 at an all-in sustaining cost well below the company's portfolio average, making it a disproportionate contributor to group margins. Any extended interruption therefore carries significance beyond the raw ounce count: it compresses cash flow at a time when Barrick and its peers have been leaning on high-grade African mines to offset declining grades at older North American and Australian operations.
Flooding Scope and Infrastructure Damage
According to a company statement released Monday, unusually heavy rainfall in the Kayes region during May has overwhelmed drainage infrastructure at both the Loulo underground mine and the Gounkoto open pit. Water ingress at Loulo's deeper levels triggered an emergency suspension of underground haulage, while surface haul roads at Gounkoto have been rendered impassable. The company stated that no injuries were reported and that employees have been safely redeployed to surface maintenance roles pending water removal.
Barrick said it has mobilised additional pumping capacity and is working with local contractors to reinforce drainage channels, but acknowledged that a full return to normal throughput may not occur before late June at the earliest. The processing plant at Loulo, which handles ore from both pits and the underground operation, has been placed on care-and-maintenance mode, consuming power and labour with no corresponding output.
Broader Supply Implications
The Loulo-Gounkoto disruption arrives against a backdrop of already-tight global gold mine supply. The World Gold Council's latest data show that total mined gold output in the first quarter of 2026 grew by only 1.2 percent year-on-year — the slowest rate of growth since 2023 — as grade decline at mature operations in South Africa, Australia, and Canada offset volume gains from newer projects in West Africa and Ecuador.
West Africa has in recent years assumed a larger share of global gold production, with operations in Mali, Senegal, Burkina Faso, and Côte d'Ivoire collectively accounting for an estimated 8 to 9 percent of world supply. That concentration creates systemic exposure to regional weather events, political developments, and infrastructure constraints. Analysts at BMO Capital Markets noted in a morning briefing that Monday's guidance revision from Barrick is "a timely reminder that West African mine schedules carry a wider confidence interval than equivalent assets in more stable jurisdictions."
Other Producers and Market Reaction
Spot gold edged 0.4 percent higher in early London trading following Barrick's announcement, reaching approximately $4,538 per troy ounce, as traders factored in a modest near-term tightening of physical supply. The move was contained, however, reflecting the fact that the lost ounces represent a fraction of annual global mine output of roughly 3,600 tonnes.
Rival operator Allied Gold, which operates the Sadiola mine in the same general region of Mali, said through a spokesperson that it has not experienced material flooding at its own operations but is monitoring conditions closely. AngloGold Ashanti, which exited Mali in 2023, declined to comment.
Barrick said it would provide a further update at its scheduled second-quarter operational review in July. In the meantime, the company indicated it would attempt to partially offset the lost Loulo-Gounkoto output by accelerating mining rates at its Kibali operation in the Democratic Republic of Congo, where ground conditions remain favourable.
The episode underscores an increasingly familiar challenge for the gold mining sector: sustaining production volumes in a world where the most accessible deposits have been exhausted, forcing operators deeper into geographically or logistically complex environments where weather, infrastructure, and political risk loom larger than they once did.
