Lundin Mining has cut 2026 copper guidance at its high‑altitude Caserones mine in Chile’s Atacama region to 120,000–130,000 tonnes, from 130,000–140,000 tonnes, after a second severe winter storm caused fresh power outages and infrastructure damage. The storm on 13–14 August brought heavy rain, strong winds and unusually heavy snow that damaged an already compromised transmission tower, extending downtime that began with a 12‑day outage in July and blocking access routes. Consolidated copper guidance is now 300,000–325,000 tonnes, with Caserones cash costs raised to $2.15–$2.35/lb and group costs to $1.95–$2.15/lb, underlining weather‑driven availability risk for Andean operations.

Maaden and Aramco have signed a shareholders’ agreement to create a joint venture focused on mineral exploration and hard‑rock mining across Saudi Arabia. The JV will combine Maaden’s multi‑commodity mining portfolio with Aramco’s capital strength and subsurface data capabilities to target new resources beyond the kingdom’s existing gold, phosphate and bauxite operations. For geotechnical and mine planning teams, the move signals a likely ramp‑up in greenfield drilling, resource definition and associated infrastructure development in under‑explored terrains.

Metso is expanding its South American service footprint with new investments in local service centres and repair capability located close to major copper and iron ore belts. The OEM is bundling on-site maintenance, component refurbishment and lifecycle services to lift uptime and throughput on its crushers, mills and screening equipment. For mine operators, the move signals greater access to OEM spares, faster turnaround on critical repairs and more scope for performance-based service contracts across the region.
