Gold briefly tops $4,050 as mine output hits quarterly record and costs rise

Spot gold (XAU/USD) rose to about $4,065/oz in a trading session after US midterm election results, gaining more than 3.60% intraday, the biggest single-day gain since mid-August, and reclaiming the psychological $4,000/oz threshold. At the same time, global mine production set a quarterly record in Q3, but total supply fell rather than rose and all-in sustaining costs continued to climb, tying the gold price rebound and mine-side supply constraints into the same set of market signals.^[4][6]

Weaker dollar and fiscal worries lift gold

In Asian morning trading cited in market commentary, spot gold (XAU/USD) rose to about $4,065/oz, gaining more than 3.60% on the day, the biggest single-day gain since mid-August. After Democrats swept the Senate and House of Representatives, the dollar fell to a more than one-month low; a weaker dollar makes dollar-priced gold cheaper for overseas buyers, boosting its appeal. Markets also worried about the US fiscal outlook, with Scotiabank analysts attributing the precious-metals rally to the dollar's move and concerns about the US fiscal outlook, and noting that silver also rose nearly 5% over the same period. Expectations that political gridlock could restrain further fiscal expansion were also seen as a factor affecting the dollar and precious-metals allocations.^[4]

However, the rate path remained a drag. The CME FedWatch tool showed the market then priced about an 82.7% probability of a US rate hike in December, and higher rates raise the opportunity cost of holding non-yielding gold. Technically, spot gold remained below its 20-day and 100-day simple moving averages, with RSI (14) at about 48, indicating neutral momentum rather than oversold conditions. Initial upside resistance sat at the 20-day Bollinger mid-band around $4,075/oz, followed by the 100-day moving average at $4,205/oz and the upper Bollinger band around $4,255/oz. Support was at the lower Bollinger band around $3,900/oz; a break below could open a deeper pullback, while holding it would keep the market in a broad range.^[4]

Global mine output sets record, but total supply falls

The World Gold Council said in its quarterly assessment that global mine production rose 3% year on year to 1,071 tonnes in Q3, a record for the third quarter. The council said mine output could set another record high, but the overall supply response should remain modest, with recycling still subdued. Weaker recycling and a further reduction in producers' outstanding hedges pushed total global supply down 1% year on year to 1,369 tonnes. That means new mine output did not translate into a matching expansion in total supply.^[6]

By country, Canada's Q3 output rose 22%, with newly commissioned projects such as Equinox Gold's Valentine mine and B2Gold's Goose mine, plus higher output at existing mines, pushing the country's growth above the global rate. Valentine entered commercial production last November and is expected to produce 140,000-150,000 oz this year. Indonesia's output rose 21%, helped by higher grades at Batu Hijau, the start-up of Pani Gold and the recovery of Grasberg production; Chile rose 19%, supported by Salares Norte and the newly commissioned Fenix project. In contrast, Australia fell 12% and the US fell 7%, due to lower grades and mine sequencing, affecting Cadia, Nevada Gold Mines and Round Mountain. Global mine output rose 2% in the first nine months and is on track for a record year unless Q4 delivers broad disappointment.^[6]

Cost curve continues to shift higher

Higher output came with higher costs. Citing Metals Focus data, the World Gold Council said the industry's average all-in sustaining cost reached a record C$2,698 (US$1,930)/oz in Q2, up 22% year on year, the fastest annual growth since early 2013. Rising energy and consumables prices and higher sustaining capital expenditure combined to push costs higher, while the cost data lag production data by one quarter.^[6]

BMO Capital Markets' GoldPages estimates showed that production-weighted sustaining costs for producers in its coverage were expected to average $1,795/oz this year, 16% higher than in 2025; after including development capital, average all-in costs were expected to rise 22% to $2,298/oz. BMO's company sample differs, but the direction is consistent with World Gold Council data, showing that higher gold prices have not eliminated cost pressure on miners.^[6]

Operational and capital-spending disruptions at individual miners

I-80 Gold maintained annual production guidance of 40,000-50,000 oz but expects to land in the lower half of the range. Contractor labour turnover in Nevada slowed mining, access to high-grade ore at Granite Creek was delayed, and some Archimedes ore was deferred to early 2027 because of a processing adjustment. The company said contractor staffing had returned to previous levels, while production mining at Archimedes and refurbishment of the Lone Tree processing plant remained on schedule.^[2]

In Q3, I-80 Gold produced 11,685 oz, down 6% year on year; revenue rose slightly to $32.7 million on stronger gold prices despite fewer ounces sold; net loss widened to $48.4 million, or 6 cents per share, from $41.9 million, or 5 cents per share, a year earlier. In early trading on the session after the disclosure, the stock fell 5.2% to C$1.83, valuing the company at about C$1.6 billion (US$1.1 billion).^[2]

Lone Tree remained central to the growth plan, with a refurbishment budget of about $430 million and first gold targeted for Q4 2027. Labour costs were 5% to 10% above the initial estimate but remained within project contingency; about 44% of capital had been committed and 20% of contingency used, above the roughly 10% mentioned in last month's update. Contract payments were made four to five months after commitment, versus an original assumption of 30 days, moving some spending into 2027. As of Sept. 30, cash and equivalents were $411.4 million, down from $464.6 million three months earlier.^[2]

What to watch

Gold's short-term rebound and mine-side supply cost pressure are emerging at the same time: on the macro side, a weaker dollar, fiscal concerns and rate expectations will determine whether gold can hold above $4,000/oz; on the supply side, record mine output has not yet translated into total supply growth, while rising costs and project execution risks continue to constrain incremental supply. Ahead, watch the impact of US employment data on rate pricing, whether Q4 mine output can deliver a full-year record, and capital spending and ramp-up progress at projects such as Lone Tree.^[4][6][2]
