en.Wedoany.com Reported - International copper prices continued their strong momentum, closing at 633.5 cents per pound ($6.33/lb) on the London Metal Exchange (LME) on Tuesday, with a daily gain of 1.06%.

According to the daily report "La Rueda" published by the Chilean Copper Commission (Cochilco), copper prices also broke through the $13,966 per ton mark, consolidating one of the highest levels of the year. The agency's data indicates that the cumulative average price for 2026 stands at 589.4 cents per pound, up 38.96% year-on-year. In terms of monthly averages, the latest monthly average price reached 630.2 cents per pound, significantly higher than May's 612.7 cents per pound.

Copper inventories on the London Metal Exchange declined, dropping from 386,050 tons to 384,250 tons, a daily decrease of 1,800 tons, or 0.47%. The inventory reduction is considered one of the factors supporting high metal prices in recent weeks, against the backdrop of expected demand growth driven by electrification, infrastructure, and the energy transition.

The Cochilco report also showed that prices of other industrial metals on the LME rose in tandem. Aluminum closed at $3,855 per ton, zinc at $3,612 per ton, nickel at $19,170 per ton, and tin at $57,525 per ton. Additionally, according to reference information compiled by Cochilco, the FOB South America price for battery-grade lithium carbonate (99.5%) was $21.15 per kilogram.
