Chile's Mantoverde Mine Workers Threaten Strike from Dec 29 if Contract Talks Fail

Published: Dec 26, 2025 09:41
Workers at Capstone Copper’s Mantoverde mine in Chile are prepared to go on strike if mediation for a new labor contract fails, with a potential walkout set to begin on December 29. The 645-member union turned down a contract proposal in mid-December, clearing the way for a strike. An initial five-day government-mediated negotiation period is currently underway and may be extended by another five days if both parties agree.

[SMM Brass Billet Express] Copper prices fluctuated at highs in January, putting pressure on raw material procurement, while orders for brass billets contracted in industries such as valves and sanitary hardware due to difficulties in raising prices. Affected by high costs and reduced orders, some small copper billet enterprises began their holidays early from mid-to-late January. Currently, enterprises generally maintain low inventories to mitigate risks, with sample enterprises averaging only 3.95 days of raw material inventory and approximately 6.77 days of finished product inventory, reflecting overall weak stockpiling sentiment.
