State-owned copper giant Corporación Nacional del Cobre de Chile (Codelco) is finalizing a definitive partnership with private miner Compañía Minera Pucobre SA (Pucobre) to develop the US$870 million Tovaku copper project in Northern Chile, marking a strategic shift toward private sector joint ventures under the current board leadership.
The Bottom Line
- Project Valuation & Scope: The Tovaku project carries an estimated capital expenditure of US$870 million, targeting an annual output of 46 mil toneladas de cátodos de cobre de alta pureza.
- Ownership Structure: Upon completion of mandatory investment milestones and environmental approvals, Pucobre will hold a 60% controlling stake, while Codelco will retain a 40% equity interest.
- Timeline to Operations: According to data from the Chilean Mining Council (Consejo Minero), commercial production at the Antofagasta deposit is scheduled to commence by 2035.
Structuring the Tovaku Partnership
State-owned Codelco is advancing its first major public-private development under current administration leadership, moving to formalize a corporate partnership with Pucobre—a mining entity controlled by the Hurtado Vicuña and Fernández León families. Board chairman Bernardo Fontaine confirmed that the administrative framework for the joint venture is nearing completion.
Here is the math. The initiative centers on Tovaku, an oxidized copper deposit located 50 kilometers northwest of Tocopilla in the Antofagasta Region. Geological surveys indicate a resource base of 633 millones de toneladas de toneladas de low-grade ore with an average copper grade of 0,20%. Environmental processing requires navigating the Servicio de Evaluación de Impacto Ambiental (SEIA), where an Environmental Impact Study (EIA) has been under review since July of last year.
The operational framework traces back to a foundational exploration accord signed in June 2009—historically notable as Codelco’s first partnership with a domestic Chilean mining firm. Under the terms of that agreement, then designated as the Puntillas-Galenosa project, Codelco contributed the underlying mining concessions and preliminary data, while Pucobre assumed management and financing of exploration work.
Capital Expenditure and Phased Equity Milestones
Financial disclosures from Pucobre through June indicate that private capital outlays for Tovaku have reached US$40 millones. But the balance sheet tells a different story regarding long-term funding requirements. Total capital deployment will scale dramatically toward the US$870 million ceiling as engineering and construction phases advance.
According to official corporate documents, Pucobre maintains an option to acquire 60% of the mining property rights currently held exclusively by Codelco. Exercising this option is strictly contingent upon fulfilling predefined capital investment thresholds, delivering rigorous technical and economic feasibility studies, and securing all necessary environmental permits. Upon satisfying these conditions, the partners will legally incorporate a joint venture entity apportioned 60% to Pucobre and 40% to Codelco.
| Project Metric | Project Data |
|---|---|
| Estimated Total Capex | US$870 Million |
| Private Capital Invested (YTD) | US$40 millones |
| Target Annual Production | 46 mil toneladas de cátodos de cobre de alta pureza |
| Ore Deposit Size | 633 millones de toneladas (0,20% Grade) |
| Construction Employment Peak | 700 Workers |
| Operational Workforce | 550 Direct Personnel |
Projections submitted within regulatory filings outline significant regional employment impacts. The construction phase will absorb approximately 700 workers, transitioning to 550 permanent direct operational positions once commercial extraction begins. Industry projections compiled by the Consejo Minero position the operational launch window just under a decade away, targeting 2035.
Broader Corporate Strategy and Portfolio Consolidation
This alliance is not an isolated transaction.
In September of last year, Codelco finalized an operating agreement with Anglo American plc (LON: AAL) to integrate adjacent mineral resources within the Andina-Los Bronces mining district. Simultaneously, the state producer expanded into the energy transition sector through its lithium partnership with Sociedad Química y Minera de Chile (NYSE: SQM), establishing the joint venture entity Novandino Litio.
