Lundin Mining Corporation has announced the results of the integrated technical study (Preliminary Economic Assessment) for the Vicuña Project, confirming its potential as a world-class mining district. The project combines the Filo del Sol and Josemaria deposits and is operated by Vicuña Corp., a 50/50 joint venture between Lundin Mining and BHP(Lundin Mining | News, n.d.).
Vicuña Corp. has unveiled its Preliminary Economic Assessment (PEA), integrating Josemaría and Filo del Sol deposits into a unified technical roadmap for a major copper district across Argentina and Chile. Phase 1 targets the Josemaría open-pit mine and concentrator with US$7 billion capex from 2027, aiming for first production in 2030. Phase 2 develops Filo del Sol oxide resources for copper, gold, and silver recovery, while Phase 3 expands to sulfides with processing up to 293,000 tpd, including desalination and transport infrastructure. In 2026, efforts focus on engineering, procurement, earthworks, roads, and camp upgrades(Minero, 2026).
It is projected to deliver world-class annual production of approximately 395 kt of copper, 711 koz of gold, and 22 Moz of silver over a mine life exceeding 25 years.
This scale of output underscores the project’s long-term strength and multi-metal significance.
As a result, Vicuña is expected to rank among the top five copper-gold-silver operations globally.
