Llurimagua copper project 2026 tender: capex, resource and risk notes for mine planners

30 Second Briefing
Ecuador’s state miner Enami plans a 2026 international tender for the $3 billion Llurimagua copper-molybdenum project in Imbabura, designed for roughly 210,000 tpa of copper over 27 years from a 982-million-tonne resource on a 4,829-hectare concession. The move follows Codelco’s exit and an ICC arbitration that awarded the Chilean company $25.3 million, far below the more than $567 million in damages it sought. Llurimagua must still overcome a revoked 2014 environmental licence and local opposition, even as Chinese groups CMOC and Jiangxi Copper and Australia’s Fortescue step up Andean copper acquisitions.
Technical Brief
- A 2019 definitive agreement fixed ownership at 51% Enami and 49% Codelco, but JV incorporation stalled.
- Enami’s inability to finance its 51% development share blocked project company formation and delayed construction mobilisation.
- Ecuador’s 2020 mining law reform affected Codelco’s rights over ~42,600 ha of exploration ground linked to Llurimagua.
- ICC arbitration in 2025 awarded Codelco $25.3m, below both its $567m claim and ~$40m invested.
Our Take
With a 982 million tonne resource and a 27‑year mine life, Llurimagua would sit in the same long‑life Andean copper tier as Cascabel (28‑year operation life) and Peru’s Cañariaco, signalling that Ecuador is positioning Imbabura alongside northern Peru as a future large‑scale copper belt rather than a one‑off play.
The 2026 tender timing, coming after the 2025 arbitration conclusion with Codelco and following Ecuador’s 2020 mining law reform, suggests the state is trying to ‘reset’ Llurimagua under a clearer legal and fiscal regime, which bidders will likely price as reduced political but elevated social‑licence risk given the 700 ha advanced drilling footprint near Quito.
Recent Latin American copper M&A in our database—CMOC Mining’s C$581 million move on Lumina Gold’s Cangrejos and Fortescue’s C$139 million agreement for Alta Copper—indicates that any Llurimagua tender could attract both Chinese and Australian strategics already active in the region, especially those looking to secure copper plus molybdenum exposure in a single asset.
