Gold Fields Output Holds, Costs Climb 26%
Gold Fields reported higher South Deep and Tarkwa output in the September quarter while group all-in sustaining costs rose sharply.
Updated on Nov. 5, 2026 in Manufacturing
Gold Fields reported South Deep produced 80,700 ounces and Tarkwa produced 101,000 ounces in the September quarter, with production at both mines rising 5% and 4% from the preceding quarter. Group attributable gold-equivalent production declined 3% year on year to 605,000 ounces, while group all-in sustaining costs increased 26% to US$1,965/oz.
Why it matters
The rise in costs reflects pressure from higher royalties tied to gold prices, stronger producer-country currencies and increased input costs. Gold Fields said it still expects to reach the upper end of its 2.4-2.6 million-ounce annual production guidance.
Group all-in sustaining costs rose 26% to US$1,965/oz, while group attributable gold-equivalent production fell 3% year on year to 605,000 ounces. The source does not break down the individual contribution of royalties, currency and input costs to the increase.
The players
Gold Fields
Gold Fields is a South Africa-headquartered gold mining company with operations across several countries, including the South Deep mine in South Africa and the Tarkwa mine in Ghana.
The details
South Deep benefited from higher mining volumes and grades, while Tarkwa's tonnes milled rose 5% on improved plant availability and utilisation. Gold Fields attributed cost pressure to higher royalties linked to gold prices, stronger producer-country currencies and increased input costs.

Market Landscape
Gold producers' margins are increasingly shaped by royalty structures that rise with the gold price, which compresses returns even as output holds steady. Gold Fields' 26% rise in all-in sustaining costs shows that cost inflation can outpace production stability in this sector.
Higher all-in sustaining costs at gold miners can influence the valuation of mining equities and related investment funds held by households. The source does not describe any direct change to gold prices or consumer goods.
The takeaway
Output stability does not guarantee margin stability when royalties and input costs rise together. Watching all-in sustaining costs alongside production gives a clearer picture of a gold miner's financial health.
