ENAMI Prepares International Tender for $3 Billion Llurimagua Copper Project After Arbitration Tribunal Awards Codelco Just $25.3 Million of $567 Million Claim

ENAMI Plans 2026 International Tender

ENAMI — Ecuador's state-owned mining company — plans to launch an international tender in 2026 for the Llurimagua copper-molybdenum project, a development estimated at approximately $3 billion in capital expenditure.

The tender follows the definitive exit of Chile's Codelco from the project after an International Court of Arbitration ruling in July 2025 rejected most of Codelco's $567 million damages claim, awarding just $25.3 million — below the approximately $40 million Codelco invested in exploration and studies.

Project Fundamentals

Metric	Value
Location	Imbabura Province, ~80 km northeast of Quito
Resource	982 million tonnes
Annual production capacity	~210,000 tonnes copper per year
Mine life	27 years
Estimated development cost	~$3 billion
Concession area	4,829 hectares (advanced drilling on ~700 hectares)
Primary metals	Copper, molybdenum

At current copper prices (~$4.20/lb), the project's annual revenue potential exceeds $1.9 billion, positioning Llurimagua as one of Latin America's most significant undeveloped copper deposits.

The Codelco Partnership: Rise and Collapse

The Llurimagua project's history illustrates the challenges of state-private mining partnerships in Ecuador:

Date	Event
2011	ENAMI and Codelco sign initial exploration agreement
2015	Shareholder agreement signed for joint venture
2019	Definitive terms: ENAMI 51%, Codelco 49%
2020	Ecuador reforms mining law; Codelco's exploration rights threatened
2021	Codelco files international arbitration, claiming $567M in damages
July 2025	ICC Arbitration awards Codelco just $25.3M — 95.5% reduction
2026	ENAMI prepares international tender for new partner

The joint venture was never formally incorporated, in part because ENAMI could not finance its share of development costs. The partnership collapse underscores a structural challenge: Ecuador's state miner lacks the capital to develop world-class deposits alone, yet partnership terms repeatedly fail to hold.

Environmental and Community Challenges

Llurimagua faces significant non-financial obstacles that any future partner must navigate:

• Environmental license overturned: Courts struck down a 2014 environmental license, citing violations of nature rights and inadequate consultation with affected communities
• Community opposition: Long-standing resistance from environmental groups and local communities in the Intag Valley, one of Ecuador's most biodiverse regions
• Rights of Nature precedent: Ecuador's constitution grants legal rights to nature — a provision that has been successfully invoked against mining projects, including at Llurimagua
• Prior consultation requirements: Indigenous and campesino communities must be consulted under both Ecuadorian law and ILO Convention 169

The successful bidder will need to secure a new environmental impact assessment, complete prior consultation processes, and likely offer community benefit agreements beyond standard royalties.

Strategic Significance: Who Will Bid?

Llurimagua's tender arrives at a pivotal moment in Ecuador's mining sector geopolitics:

Chinese interest: Three Chinese state-linked companies — Jiangxi Copper (Cascabel), CMOC Group (Cangrejos), and CRCC-Tongguan (Mirador) — already control Ecuador's three largest undeveloped mining projects. Chinese firms have the capital and operational experience in Ecuador to be competitive bidders.

Western alternative: The US FORGE initiative ($30 billion) and EXIM Project Vault ($10 billion), announced in February 2026, specifically target critical mineral supply chain diversification away from China. Llurimagua could become the test case for whether US-backed financing can compete with Chinese offers in Ecuador.

Other potential bidders: Major copper producers including BHP, Freeport-McMoRan, Teck Resources, and First Quantum Minerals have Latin American experience and may evaluate the opportunity.

Scenario	Implications
Chinese firm wins	Consolidates Chinese dominance in Ecuador's mining sector; complicates US strategic minerals framework
Western firm wins	Validates FORGE/EXIM financing model; creates counterweight to Chinese mining presence
ENAMI retains majority	Requires creative financing; risks repeating Codelco-era capital shortfalls

Ecuador's Copper Pipeline in Context

Llurimagua joins a broader pipeline of copper projects at various stages:

Project	Operator	Status	Copper Resource
Cascabel	Jiangxi Copper	Acquisition in progress	10.9M tonnes
Mirador	CRCC-Tongguan	Operating	3.2M tonnes
Llurimagua	ENAMI (tender)	Pre-development	TBD (est. world-class)
Warintza	Solaris Resources	Exploration	5.3M tonnes
Loma Larga	Dundee Precious	Permitting	Copper-gold

Ecuador's Mining Chamber projects mining exports will reach $4 billion in 2025, driven by higher gold and copper prices and increased production at Fruta del Norte and Mirador.

What to Watch

Track ENAMI's tender specifications and timeline — the terms will reveal whether the state seeks a majority stake (as with Codelco) or accepts a minority position for capital access. Monitor environmental permitting progress — a new EIA is prerequisite to any development, and the Intag Valley opposition has successfully blocked previous attempts. Watch for US or Chinese government statements on Llurimagua specifically — the project may become a proxy for broader supply chain competition. Track the arbitration payment — Ecuador's $25.3 million obligation to Codelco must be settled before the tender proceeds cleanly.
