METALS — Copper edges up on mine supply disruption, tight stocks

(Adds analyst comment, updates prices) Oct 13 (Reuters) — Copper prices rose for a third straight session on Tuesday as persistent concerns over a supply shortage kept the metal within striking distance of an all-time peak. Benchmark three-month copper on the London Metal Exchange was up 0.1% at $14,636.50 a metric ton as of 0915 GMT, close to the record $14,875 seen last month. Supply concerns remained in focus after Chile's Codelco partially suspended operations at its El Teniente mine following a landslide, while Antofagasta's Centinela copper mine and two unions were set to resume talks as a strike continued. "Copper continues to benefit from physical-market tightness and declining exchange inventories, helping it withstand the firm dollar better than the wider complex," Sucden Financial said in a note. A stronger greenback makes dollar-denominated metals more expensive for holders of other currencies. The dollar took a breather on Tuesday but hovered near an 18-month high. All reported copper mine disruptions for 2025-26 — including at Indonesia's Grasberg mine and Kamoa-Kakula in the Democratic Republic of Congo — amount to 350,000-400,000 tons per year of contained copper, w
