【Zinc Concentrate Tender】According to SMM, a zinc mine in Southwest China recently concluded its July zinc concentrate tender, with the mine pickup tender price settling at around -RMB 800 per metal tonne, down approximately RMB 700 per metal tonne from the previous month. SMM will continue to monitor subsequent changes in zinc concentrate treatment charges (TCs).

Russian base metal producer Norilsk Nickel expects the global copper concentrate market to remain in undersupply in 2026, with a deficit of 751,000 mt, which will continue to put pressure on processing enterprises' profits.The company stated in its copper market outlook report released on June 23 that benchmark treatment charges (TCs) for copper concentrates under the 2026 annual contract framework have been set at $0/mt, down from $21/mt in 2025, as smelting capacity continues to compete for scarce concentrate supply.

According to the latest customs data, China imported 396,500 metric tons (gross weight) of zinc concentrate in May 2026, down 11.42% (51,100 metric tons) from April and 19.31% lower year-on-year. Cumulative imports during January–May reached 2.3987 million metric tons, representing an increase of 8.84% compared with the same period last year.

Time flies as the midpoint of 2026 approaches. The zinc concentrate market has witnessed another extraordinary price cycle this year. As of June 12, domestic zinc concentrate treatment charges (TCs) plunged to -50 yuan per metric ton of zinc metal, marking the arrival of negative TCs. Meanwhile, TCs for imported zinc concentrate tumbled to -71.2 US dollars per dry metric ton, both hitting all-time record lows.

Central Asia Metals (CAML) announced that, thanks to improved operational efficiencies, its copper and zinc production for the first five months of 2026 both surpassed the same period last year. Copper output from the Kounrad operation in Kazakhstan totalled 5,141 tonnes, a near 4% increase over the last year. Meanwhile, the Sasa mine in North Macedonia produced 7,566 tonnes of zinc in concentrate, up over 2% compared to last year. In terms of pricing, the company reported significantly higher realized metal prices during the period. The average price of copper reached $13,076 per tonnes, representing a massive jump of nearly 40% over the last year, while average zinc prices rose 19% to $3,299 per tonne. In addition, historically low treatment charges for lead, which have turned negative, further boosted Sasa’s revenues. CEO Gavin Ferrar noted that the group is shaping up to deliver strong profitability and cash generation in the first half of 2026. Currently, the company is actively pushing forward with its acquisition of Australia's Cygnus Metals, announced last week, to expand its footprint into a high-grade copper-gold project in Quebec, Canada. The company remains highly confident in meeting its full-year production guidance (12,000–13,000 tonnes of copper, 18,000–20,000 tonnes of zinc concentrates, and 26,000–28,000 tonnes of lead concentrates).

【Domestic Zinc Concentrate Market】Domestic smelters maintained steady purchasing volumes of domestic zinc concentrate this week, and the tight supply pattern of domestic zinc concentrate persisted. Treatment charges kept edging down across most regions. Except for individual northern provinces, treatment charges for domestic zinc concentrate have generally slipped into negative territory nationwide.
