Gold Miner Expands Mines in Three Countries
Mining suppliers serving Tanzania, Brazil and Guinea should expect project demand to rise as expansions proceed.
Updated on Nov. 5, 2026 in Corporate Finance
AngloGold Ashanti, the world's fourth-largest gold miner by output, plans to invest $900 million in expansions to lift annual gold production. The company reported a 12% rise in third-quarter EBITDA to $1.57 billion, supported by higher bullion prices, and operators in the mining supply and contracting chain should watch where that capital is directed.
Why it matters
The plan grows output at existing mines rather than through new sites, which the company says leverages current infrastructure to maximise returns. For businesses that supply equipment, power, logistics and engineering to gold mining, the spending points to where demand will concentrate across Tanzania, Brazil and Guinea over the coming years.
The company's third-quarter EBITDA rose 12% to $1.57 billion, and it produced 2.164 million ounces in the nine months to September 30 against a 2026 target of 2.8 to 3.17 million ounces. The Geita expansion in Tanzania is budgeted at $480 million to $580 million and the Cuiabá expansion in Brazil at $200 million to $250 million. Whether these projected costs and output gains will hold is not yet established.
The players
AngloGold Ashanti
A large gold producer and the world's fourth-largest by output, operating mines across Africa and South America.
The details
Rather than building new mines, AngloGold is adding capacity at Geita in Tanzania, Cuiabá in Brazil and Siguiri in Guinea, all of which use infrastructure already in place. The Cuiabá expansion adds 75,000 ounces to the 194,000 ounces it produced in 2025, while a further $70 million at Siguiri is expected to add 100,000 ounces to the 289,000 ounces that mine produced last year. The company is targeting at least 400,000 additional ounces a year by the end of the decade, with Geita alone reaching 600,000 ounces annually by 2030.
Timeline
2025: Geita produced 492,000 ounces and Cuiabá produced 194,000 ounces.
September 30: End of the nine-month period in which 2.164 million ounces were produced.
2026: Company output target of 2.8 to 3.17 million ounces.
By 2030: Geita expansion expected to reach 600,000 ounces a year.
End of the decade: Goal to lift annual production by at least 400,000 ounces.
Market Landscape
AngloGold's strategy of expanding existing mines rather than opening new ones favours brownfield growth, which generally requires less upfront infrastructure spending than building from scratch. The projected 35% real internal rate of return sets a benchmark that rival producers pursuing expansions will be measured against.
Suppliers to gold mining in Tanzania, Brazil and Guinea should expect project activity around the Geita, Cuiabá and Siguiri expansions to rise over the coming years. Operators should weigh whether their own capacity and cost structures can meet demand tied to these multi-year builds.
The takeaway
Capital allocation toward expansions at existing sites is a model worth tracking as a signal of how mid-tier and large producers manage cost and growth. Operators supplying mining projects should track the company's next quarterly production report against its 2026 target range to gauge how quickly contracted demand may materialize.
