The situation is exacerbated by China's planned halt on sulfuric acid exports, which could impact global copper output. Ivanhoe Mines is expected to benefit from this supply squeeze, while Capstone Copper and Lundin Mining may face cost challenges in their Chilean operations. Current copper price stands at $78.52, down 4.52%."

# Copper Equities Down 5.5% Week over Week, RBC Says

11:47 AM EDT, 04/28/2026 (MT Newswires) -- Copper equities fell 5.5% over the past week driven by a pullback in gold, a firming U.S. dollar, and a sharp oil rally, as markets digest the spillover effects of the war in Iran, RBC Capital Markets said Monday.

Sulfuric acid availability remains in focus as China plans to halt acid exports in May to prioritize domestic fertilizer and battery production. Prices are reaching about $1,000 per tonne, threatening leaching operations that represent 20% of global copper output, while operations in the Democratic Republic of Congo rely primarily on Middle Eastern acid.

Ivanhoe Mines ( IVPAF ) stands out as a clear beneficiary of this acid supply squeeze, with the newly commissioned Kamoa-Kakula smelter producing 1,200 tonnes per day of acid that could generate over $400 million in annual byproduct revenues at spot prices.

Capstone Copper ( CSCCF ) and Lundin Mining ( LUNMF ) face potential cost headwinds from their

Chilean leaching operations, although local supply chains and term contracts could provide insulation in the near term, RBC said.

Price: 78.52, Change: -3.72, Percent Change: -4.52
