What Led to the Arbitration Proceedings?

The arbitration proceedings arose from a fundamental breakdown in the planned joint venture structure, with each side accusing the other of failing to fulfill their contractual obligations. What began as a promising international partnership deteriorated into accusations of bad faith and contractual violations.

Original Joint Venture Agreement Terms

The 2016 agreements established a framework with several key provisions:

• Ownership structure: 51% Enami EP, 49% Codelco
• Codelco would lead technical exploration and development activities
• Formation of a joint operating company to manage the project
• Phased development approach with clear milestones
• Technical knowledge and data sharing protocols
• Joint investment commitments for project advancement

Alleged Breaches of Agreement

Codelco's arbitration claims centered on several alleged breaches by Ecuador:

• Failure to finalize the joint venture formation: Despite years of preparation, Ecuador allegedly failed to complete necessary steps to establish the operating company
• Negotiation breakdowns: Codelco claimed Ecuador "failed to negotiate with shareholders in good faith" as required by their agreements
• Operational impediments: Delays in permitting and administrative approvals allegedly hampered exploration work
• Intellectual property disputes: Disagreements emerged over ownership and use rights for geological data generated during exploration

Financial Stakes in the Dispute

The financial implications of the dispute were substantial:

• $567.7 million: Codelco's original claim against Ecuador
• Exploration investment: Codelco invested significant capital in drilling, geological analysis, and resource definition
• Maintenance costs: Ongoing expenses to maintain the project site during disputes
• Strategic value: Llurimagua represented a rare opportunity for Codelco to secure a major resource outside Chile
• National interests: For Ecuador, the project represented a significant potential contributor to GDP and export revenue

How Did the Arbitration Ruling Impact Both Parties?

The July 2025 ICC arbitration ruling produced a complex outcome that allowed both parties to claim victory, though the financial award represented just a fraction of Codelco's original claim.

The ICC's $25 Million Award

The International Chamber of Commerce tribunal ordered Ecuador to pay $25.3 million to Codelco, a figure representing less than 5% of the Chilean miner's original $567.7 million claim. This award included:

• Compensation for specific exploration phase costs
• Reimbursement for site maintenance expenses
• Interest accrued during the dispute period

This figure was significantly below Codelco's expectations but represented an acknowledgment of Ecuador's partial responsibility for the breakdown in relations.

Ownership and Control Outcomes

Despite the financial award, the ruling produced clear outcomes regarding project control:

• Enami EP retained full ownership and control of the Llurimagua project
• Codelco maintained ownership rights to the geological information it generated during exploration
• Ecuador's request for mandatory handover of geological data was rejected
• No provisions were made for Codelco's future involvement in the project

This outcome effectively ended Codelco's direct participation in Llurimagua's development while preserving its intellectual property rights to the valuable geological data collected.

Competing Victory Narratives

Following the ruling, both parties issued statements framing the outcome as favorable:

• Ecuador's Attorney General: Characterized the ruling as "a resounding legal victory for Ecuador" that saved the state approximately $540 million from the original claim
• Codelco's Statement: Emphasized that "the court determined that Ecuador incurred civil responsibility for failing to comply with agreements" and failing to negotiate in good faith

These contrasting perspectives highlight how arbitration outcomes can be interpreted through different lenses depending on initial expectations and political considerations.

Legal Analysis: "The ICC ruling represents a middle-ground solution typical in complex mining arbitrations. While Ecuador avoided the full financial liability, the ruling established important principles regarding data ownership and contractual compliance that will influence future state-to-state mining partnerships." — International Arbitration Review, 2025
