[Flash | Chile's Weather Bites Back: Caserones Copper Guidance Slashed, Molybdenum Caught in the Crossfire]

Published: Sep 07, 2026 09:26 (GMT+8)
Chile's Caserones copper-molybdenum mine was previously affected by extreme winter weather, experiencing two winter storms that disrupted power supply and site access, causing an actual impact on mine production. The impact of this event has now carried over from a short-term operational disruption into full-year output expectations: Lundin Mining subsequently lowered its full-year copper production guidance for Caserones from the original 130,000–140,000 tonnes to 120,000–130,000 tonnes. By-product molybdenum output is expected to come under pressure in tandem, though a specific molybdenum production guidance figure has not yet been separately disclosed.

Kobrea Exploration Corp. announced the approval of a US$4 million 2026/27 exploration programme for the Western Malargüe Mining District in Mendoza Province, Argentina, fully funded by BHP. The programme includes diamond drilling at the El Destino copper-gold-molybdenum porphyry target, induced-polarisation surveys at El Destino and KBX-17, as well as geological mapping, geochemical sampling and hyperspectral work. The exploration alliance covers seven projects totaling approximately 733 square kilometres, where copper, gold and molybdenum geochemical anomalies have been identified. SMM analysis: approval of the new budget moves the BHP-Kobrea partnership from an alliance framework into an active drilling phase. However, the properties remain at an early exploration stage, with no molybden

Glencore plans to submit the environmental impact report for its El Pachón copper-molybdenum project in Argentina in Q1 2027 and aims to secure approval under the Incentive Regime for Large Investments, or RIGI, before July 2027. Glencore previously reported approximately 6 billion tonnes of mineral resources grading an average 0.43% copper, 2.2 g/t silver and 130 g/t molybdenum, equivalent to around 0.013% Mo. Based on the disclosed tonnage and average grade, the resource contains roughly 780,000 tonnes of in-situ molybdenum, although this does not represent reserves, recoverable metal or future production. During the 2025/26 exploration season, the project completed 53 drill holes totaling 21,246 metres and advanced preliminary road and bridge infrastructure.
