[SMM Copper Morning Briefing] News:
(1) On September 19 (Saturday), Sprott Asset Management said that despite copper prices hitting record highs, global mine copper production is likely to see its first decline in nearly a decade this year, affected by production disruptions, falling ore grades, and weak output in Chile. This also highlights the slow supply response of miners to higher prices.
Sprott's latest report showed that mine copper production fell 1.1% YoY in H1 2026. Production disruptions at Freeport-McMoRan's Grasberg copper mine in Indonesia and Ivanhoe Mines' Kamoa-Kakula copper complex in the DRC together reduced expected 2026 production by about 600,000 mt, accounting for roughly 2.5% of annual global mine copper output.
Jacob White, head of ETF product management at Sprott Asset Management, wrote in the report: "Higher prices can improve project economics, but they cannot compress the full project development cycle, nor can they quickly replenish exploration discoveries." He noted that copper mine projects take an average of about 17.5 years from discovery to production.
Supply-side constraints are compounded by growing copper demand from power grids, AI data centers, and national defense, while US tariff policies have driven massive volumes of copper cathode into US warehouses. Toronto-based Sprott data showed copper prices rose 47% in the 12 months through August.
Spot:
(1) Shanghai: On September 18, SMM #1 copper cathode spot prices against the SHFE copper 2610 contract were quoted at premiums of 660-810 yuan/mt, with an average premium of 735 yuan/mt, down 15 yuan/mt from the previous trading day. The SHFE copper 2610 contract shot up in early trading before consolidating lower. After the open, prices edged up, briefly rising to around 109,620 yuan/mt, then quickly pulled back to around 109,400 yuan/mt. Copper prices subsequently rebounded, but upward momentum was limited, and futures consolidated, with prices rebounding slightly multiple times before pulling back. Prices recovered modestly near midday, and the morning session closed at 109,500 yuan/mt. The Back month spread was between 360 yuan/mt and 400 yuan/mt, and the import profit margin for SHFE copper against the 2609 contract was between a loss of 1,000 yuan/mt and a loss of 410 yuan/mt. During the day, the sales sentiment for copper cathode in Shanghai was 3.31, up 0.41 MoM, and the procurement sentiment was 3.54, up 0.62 MoM. Historical data can be queried in the database. Looking ahead to this week, the tight supply-side pattern is expected to continue supporting spot premiums. According to SMM, from October to November, multiple domestic copper smelters will enter planned maintenance periods. Against the backdrop of persistently tight supply of copper concentrates and blister copper and copper anode, production and shipment pace at some smelters may be affected to some extent, with limited growth in available market supply. Meanwhile, port congestion in Shanghai has not fully eased, and the arrival pace of imported copper remains uncertain, making it difficult for short-term imported supply to see a significant increase. Demand side, with copper prices staying high, downstream procurement remains primarily need-based, with limited acceptance of high premiums. Overall, if arrivals do not increase significantly this week, spot premiums in the Shanghai market are expected to continue to consolidate at highs.
(2) Guangdong: On September 18, spot #1 copper cathode in Guangdong against the front-month contract: high-quality copper was quoted at a premium of 900 yuan/mt, up 200 yuan/mt from the previous trading day; standard-quality copper was quoted at a premium of 700 yuan/mt, up 150 yuan/mt from the previous trading day; SX-EW copper was quoted at a premium of 640 yuan/mt, up 150 yuan/mt from the previous trading day. The average price of #1 copper cathode in Guangdong was 110,255 yuan/mt, up 1,620 yuan/mt from the previous trading day, and the average price of SX-EW copper was 110,095 yuan/mt, up 1,595 yuan/mt from the previous trading day. The purchase sentiment for copper cathode in Guangdong was 2.61, up 0.05 from the previous trading day, while the selling sentiment was 2.70, down 0.07 from the previous trading day (historical data can be queried in the database). Overall, with inventories continuing to decline, suppliers actively held prices firm, driving premiums sharply higher.
(3) Imported copper: On September 18, the average warrant price rose $3/mt from the previous trading day to $124/mt (price range: $118-130/mt); the average B/L price was flat from the previous trading day at $116/mt (price range: $112-120/mt); the average price of EQ copper (CIF B/L) was flat from the previous trading day at $65/mt (price range: $60-70/mt), with quotes referencing cargoes arriving from September to mid-to-late October.
(4) Secondary copper: On September 18 at 11:30, the futures closing price was 109,500 yuan/mt, up 1,130 yuan/mt from the previous trading day. The average spot premium was 735 yuan/mt, up 105 yuan/mt MoM from the previous trading day. Copper scrap prices rose 800 yuan/mt MoM. The selling sentiment index for copper scrap rose to 2.71, while the purchase sentiment index fell to 1.91. The price difference between copper cathode and copper scrap was 2,936 yuan/mt, up 315 yuan/mt MoM. The price difference between copper cathode rod and secondary copper rod was 1,540 yuan/mt. According to SMM survey, as copper prices continued to recover, selling sentiment among copper scrap suppliers improved. However, with secondary copper rod prices forced to carry premiums due to high raw material costs, purchase willingness among end-user wire and cable enterprises remained very weak. With insufficient new orders for secondary copper rod, purchases of high-priced raw materials were limited.
Prices: On the macro front, Trump is open to meeting with the Iranian president at the UN General Assembly, while also saying he is considering thorough military action against Iran; Qatar said the US wants to reach a deal, and the Houthis agreed not to engage in war with the US. Trump will speak at the UN General Assembly on Tuesday, the Iranian president will speak on Wednesday, Netanyahu's visit to the US was unusually brief, and Turkey may provide defense assistance to Saudi Arabia. The pullback in crude oil eased inflation expectations, providing support for copper prices. On the fundamentals side, available supply remained tight, with suppliers holding prices firm and holding back from selling, keeping the overall supply situation tight. On the demand side, purchase sentiment rebounded sharply MoM, and downstream purchase willingness improved, but purchases remained primarily just-in-time, with limited acceptance of high premiums. Overall, copper prices are expected to drift higher today.

Centinela Strike Could Cut November Copper Output by Half, Unions Say

A workers’ strike at Antofagasta’s Centinela copper mine in Chile could reduce the operation’s November copper production by around 50% if the work stoppage continues, according to union representatives. The strike began on October 7 after two unions rejected further negotiations with Antofagasta Minerals following the failure of government-mediated talks to produce an agreement. The labour groups represent more than half of Centinela’s critical mine operators and more than 60% of equipment maintenance workers. The unions said the initial operational impact is expected to worsen gradually because mining and mine-development activities have been affected, while a large volume of waste rock still needs to be removed. They expect the full effect of the strike to become more visible in November, when production could fall by as much as half. Antofagasta has said it continues to maintain its production guidance despite the strike and declined to comment on the unions’ estimate of the potential November production impact. The dispute centres on differences in pay and benefits between union groups. Labour representatives are seeking equivalent benefits for employees regardless of union affiliation, while Antofagasta has said bargaining schedules have been separated since 2020 and wage adjustments have been negotiated at different times. The union estimate of a potential 50% decline in November production materially increases the supply significance of the Centinela strike compared with the initial work stoppage. However, the estimate has not been confirmed by Antofagasta, which continues to maintain its production guidance. The scale of any actual copper loss will therefore depend on the duration of the strike, the extent of disruption to mining and maintenance activities, and whether negotiations resume before November.

Magna Mining Approves Levack Mine Restart, Targets Mid-2028 Commercial Production

Magna Mining has approved the restart of its fully permitted Levack Mine in Ontario, Canada, following completion of a Preliminary Economic Assessment that outlines 7.3 years of commercial production and estimated initial capital requirements of C$70.1 million. The PEA outlines average annual payable production of approximately 36.8 million lb of copper-equivalent over the commercial production period, with output comprising nickel, copper and precious metals. Magna is targeting the start of commercial production in mid-2028. The study estimates an after-tax NPV at a 7% discount rate of C$227.0 million, an after-tax IRR of 92.4%, and a payback period of 0.6 years under the base-case assumptions used in the PEA. The development plan involves restarting the existing underground operation and utilizing established mine infrastructure. Following board approval, Magna plans to advance detailed engineering, underground development and other activities required to support the proposed restart schedule. The PEA includes approximately 2.1 million short tons of Inferred Mineral Resources. Magna cautioned that the assessment is preliminary in nature and that the restart decision was not based on a feasibility study of Mineral Reserves demonstrating economic and technical viability. The board approval moves Levack from technical evaluation toward restart execution, with commercial production targeted for mid-2028 and initial capital estimated at C$70.1 million. The strong PEA economics indicate potentially attractive project returns under the study assumptions, but the inclusion of Inferred Mineral Resources and the absence of a feasibility-level reserve case mean execution and economic uncertainty remain material. Attention will now turn to detailed engineering, underground development and capital deployment as Magna advances toward the planned restart.

Ivanhoe Reports 76,401 mt Q3 Copper in Saleable Products at Kamoa-Kakula, Guidance Trends Toward Lower End

Ivanhoe Mines reported that the Kamoa-Kakula Copper Complex in the Democratic Republic of Congo produced 76,401 mt of copper in saleable products in Q3 2026, up approximately 19% from 64,328 mt in Q2. The company maintained its 2026 production guidance of 290,000–310,000 mt, while stating that output is trending toward the lower end of the range. Q3 saleable copper comprised 61,506 mt of copper in anode, 2,347 mt of toll-treated copper in blister, 5,645 mt of copper in slag concentrate, and 6,904 mt of high-grade copper fines designated for sale. Ivanhoe said the high-grade fines had been produced previously and stockpiled before being assayed, surveyed and designated for sale during the quarter. The Phase 1, 2 and 3 concentrators processed a combined 3.493 million mt of ore during Q3, compared with 2.968 million mt in Q2. Combined feed grade averaged 2.22% copper, while recovery reached 87.6%, compared with 87.4% in the previous quarter. Copper contained in concentrate increased to 68,188 mt from 61,134 mt in Q2. Mining rates across Kamoa and Kansoko increased by approximately 30% to more than 700,000 mt/month, equivalent to around 8.5 million mt/year. Ivanhoe said higher mining rates are expected to continue supporting production as underground operations recover. Kamoa-Kakula’s on-site smelter remained at around 60% of its 500,000 mt/year design capacity during the quarter. The smelter also produced a record 118,638 mt of high-strength sulphuric acid in Q3. Ivanhoe continues to work on improving concentrate quality and reducing silica levels that have contributed to increased slag concentrate production. Kamoa-Kakula’s Q3 saleable copper output increased approximately 19% quarter on quarter, supported by higher mining rates, increased concentrator throughput and the designation of previously stockpiled high-grade copper fines for sale. However, Ivanhoe’s indication that 2026 production is trending toward the lower end of its 290,000–310,000 mt guidance range shows that the complex remains in a recovery and ramp-up phase.
