Two headline numbers from the same World Gold Council dataset seem, on the surface, to pull in opposite directions — but read together, they tell a coherent story about where gold actually comes from, and why supply-side news like this eventually shows up in the price of a piece of jewellery.
Global gold mine production hit an all-time quarterly record of 966 tonnes in the second quarter of 2026 — and in the same period, the industry's cost of getting that gold out of the ground also hit a record, with all-in sustaining costs reaching US$1,785 an ounce, up 5% quarter-on-quarter and 16% year-on-year, according to Mining.com's coverage of World Gold Council data. At first glance, record output and record costs happening simultaneously might look like a contradiction. It isn't — and understanding why explains a lot about why gold jewellery prices have moved the way they have this year.
Where the Extra Gold Actually Came From
The production gains weren't spread evenly. Canada led with a 29% increase as new and expanding operations ramped up, including Agnico Eagle's Detour Lake mine. Chile added 24% following Gold Fields' Salares Norte project reaching steady-state output and the commissioning of Rio2's Fenix mine. Burkina Faso rose 17% on higher mill throughput and a first full quarter of hard-rock mining at a newly commissioned operation. Meanwhile, Mexico's output actually dropped 23% as Newmont's Peñasquito mine transitioned to a lower-grade phase not expected to improve until 2028 — a reminder that even in a record-output quarter, individual mines still move in very different directions.
Why Costs Rose Even as Output Rose
Rising all-in sustaining costs reflect a mix of pressures largely outside any single miner's control: higher royalties (which scale with the gold price itself, so as gold gets more valuable, governments and landowners take a proportionally larger cut), energy inflation — with oil trading above US$90 a barrel pushing up diesel and fuel costs for mining equipment worldwide — and general cost inflation across labour and materials. None of these pressures are unique to gold mining, but gold miners feel them acutely given how equipment- and energy-intensive extraction is.
The Part That Actually Matters: Margins
Here's the key point often lost in the "record costs" headline: costs rose 16% year-on-year, but gold's price rose considerably more than that over the same period. With gold averaging roughly US$4,872.90 an ounce in the first quarter of 2026 against an AISC of US$1,785, the implied operating margin came in close to US$3,100 an ounce — one of the widest spreads in the industry's history, according to the same Mining.com analysis. Separately, S&P Global's 2026 Mine Cost Outlook projected industry-wide AISC would actually decline roughly 5% for the full year even as gold prices were forecast to rise around 24%, implying record margins of approximately US$2,800 an ounce for the year as a whole, according to analysis from Merchant Gold Group.
Margins Have Been Widening for Years, Not Just This Quarter
This isn't a one-quarter anomaly. The trend of margins expanding even as costs rise has been building for several years, as gold's price gains have consistently outpaced input cost inflation across the mining sector. Analysts at asset managers covering the space have described gold miners as generating record margins and free cash flow, with disciplined capital allocation and industry costs holding below US$2,000 an ounce through much of the year — a combination that's left the sector well positioned even if prices were to stabilise or ease somewhat from current levels.
Why This Actually Matters for Jewellery Shoppers, Not Just Investors
It's easy to assume mining economics are a story purely for stock investors, but there's a direct line from this data to what you pay at a jewellery counter. The AISC figure functions as a long-run price floor for gold: when the gold price falls meaningfully below the industry's average cost of production, miners start losing money on marginal operations, which eventually forces mine closures and reduces future supply — a self-correcting mechanism that has historically put a soft floor under gold prices over multi-year periods. With AISC now sitting at a record US$1,785 and climbing, the level at which mining supply would start meaningfully contracting has risen right alongside it. In plain terms: there's a structural reason gold isn't likely to become dramatically cheaper any time soon, regardless of short-term price swings.
That's a useful piece of context if you've been waiting for a big price drop before making a purchase. It doesn't mean prices can't ease in the near term — they have, several times this year — but the mining industry's own cost structure suggests a return to the much lower prices of a few years ago isn't the base case most analysts are working from.
A Note From Starlight Jewellery
None of this changes what actually matters when you're choosing a piece: design, purity, and how efficiently a piece uses its gold. Our wide, modestly designed collection of lightweight rings is built with exactly this kind of price environment in mind, and with Buy Now, Pay Later available at checkout, you don't need to wait for a mining-driven price correction that may not come to bring home a piece you love today.
