Codelco, Collahuasi and Technical Governance in Chilean Copper
By Marta Rivera Muñoz and Eduardo Zamanillo
Chile has moved two important pieces in its copper leadership map, Jorge Gómez Díaz, after fourteen years leading Collahuasi, will become president and chief executive officer of Codelco on July 13, 2026. Patricio Hidalgo, currently president of Anglo American in Chile, will assume leadership of Collahuasi on July 1, 2026. The sequence is immediate and relevant: one of Chile’s most experienced copper executives moves from a major private joint venture to the state owned copper company, while Collahuasi enters a new leadership stage under an executive coming from one of its principal shareholders. The immediate story is executive succession. The deeper story is governance, expressed through institutional roles under pressure.
Gómez arrives at Codelco as an operator tested in a complex mining system. Hidalgo arrives at Collahuasi as the steward of an independent joint venture entering a new phase of growth, water infrastructure and permitting complexity. The role of governance, in both cases, is to create the conditions in which technical leadership can be accountable and effective. For Chile, copper is a national asset, a fiscal pillar and a strategic material in the global economy. It supports electricity grids, data centers, transmission networks, industrial infrastructure, defense systems, urbanization, renewable energy and the broader material base of modern life. In this context, the quality of governance inside Chile’s most important mining companies has become a strategic variable. Gómez’s move from Collahuasi to Codelco matters because it brings into the state owned copper company a leader associated with operational discipline, technical experience and the management of complex mining systems. Codelco highlighted his operational and management experience, his leadership of high-performance teams and his role in positioning Collahuasi among the most relevant, efficient and safe operations in the global mining industry. Codelco also stated that his mandate will focus on safety, profitability, maximizing contributions to the State, management control, and operational, environmental and social sustainability.
The question now is larger than Codelco itself. Chile has appointed a technically strong executive to lead its most strategic copper company. The question is whether the state owned copper system around him (the board, public authorities, internal controls and political environment) can give that mandate enough clarity, accountability and operating space to work.
That is why this transition matters. In copper, reserves are only the starting point. Supply is built through decisions made every day inside the operation: mine sequencing, safety, maintenance, water, energy, capital discipline, labor, communities, reporting and project execution. When those decisions are protected by technically competent governance, complexity can become reliable production. When they are absorbed by noise, the system loses focus.
Collahuasi as a governance case
Unlike many mining assets where one shareholder acts as the clear operator and the others participate mainly through ownership or governance rights, Collahuasi operates through a more balanced structure. Anglo American and Glencore each hold 44%, while Japan Collahuasi Resources B.V. holds the remaining 12%. This creates a different kind of governance challenge: the mine is not simply managed under the operating culture of one parent company. It must integrate the standards, expectations, technical systems and corporate cultures of two top-tier global mining companies with equal ownership weight.
That balance is part of what makes Collahuasi relevant as a case study. The company is described as an independently managed joint venture, located in the Tarapacá Region, with important growth opportunities and potential synergies with Quebrada Blanca. But independence in this context does not mean absence of shareholder influence. It means the capacity to translate different shareholder systems into one coherent operating logic at the mine level.
This structure matters because, before Gómez’s arrival, Collahuasi’s executive model had reflected a shareholder-balancing logic. The presidency and other key executive positions were associated with the two main shareholder groups, creating a form of internal equilibrium between Anglo American and Glencore/Xstrata. That model can be useful in a joint venture because it gives major shareholders representation and confidence. But it also creates a governance challenge: the operation can become organized around shareholder balance rather than around one integrated mine-centered management system.
Gómez’s appointment marked a different signal. He did not come from either of the two main shareholder organizations. His arrival opened the way for a leadership model less tied to shareholder rotation and more focused on selecting executives from the market according to operational capability, technical discipline and the needs of the asset itself. That distinction matters because the operation he inherited was under pressure. Gómez arrived at Collahuasi at the end of 2012, after one of the most difficult periods in the mine’s recent history. Public production figures show the scale of the challenge. Collahuasi’s copper production fell from 504,043 tonnes in 2010 and 453,284 tonnes in 2011 to 282,096 tonnes in 2012, a decline of 37.8% from the previous year. Its share of Chile’s total copper production also fell to 5.1%, compared with 8.6% in 2011 and 9.3% in 2010. The company attributed the decline to circumstantial and operational factors, including the effects of the altiplano winter and significant increases in operating costs.
The recovery that followed was visible in the numbers.
Collahuasi operating indicators
Source note: selected public indicators from Collahuasi sustainability reports, company disclosures and Glencore production reports. These indicators should be read as operational context, not as a simple causal attribution. Mining performance depends on geology, sequencing, grades, recoveries, labor, maintenance, weather, water, capital allocation and management systems.
On the cost side, Collahuasi moved from a high-cost position in 2012, with C1 at US$2.08/lb, to US$1.41/lb in 2015. By 2016 and 2017, C1 had fallen to US$1.14/lb, and by 2018 to US$1.07/lb. Collahuasi itself stated in 2018 that this placed the company in the first quartile of copper production costs. The Wood Mackenzie cost curve reinforces the same point: the operation moved from the high-cost end of the curve in 2012 toward a much more competitive position during the following management cycle.
The safety trajectory is equally important. In 2012, Collahuasi reported three fatal accidents and an accident frequency index of 1.18 per million hours worked. By 2015, the company reported no fatalities for a third consecutive year and an accident frequency index of 0.6. In 2018, the index had fallen to 0.131, which Collahuasi described as one of the lowest in the industry.
Together, these indicators make the governance case stronger. The recovery was not only about producing more copper. It was about restoring an operating system: lower costs, stronger safety performance, higher productivity, clearer risk management and greater discipline in how the mine converted plans into results. The Collahuasi case matters because the figures point to something deeper than production recovery. They show the return of operational order.
That return of operational order is the key point for this article. Collahuasi was not a simple asset waiting for better market conditions. It was a large copper operation inside a complex joint venture, with two top-tier global shareholders holding equal ownership weight, different corporate systems, different operating cultures and high operational pressure. In that structure, technical governance had to do more than balance shareholder expectations. It had to create one operating logic for the mine.
The recovery cycle suggests that Collahuasi was able to rebuild that integrated logic. Production recovered, costs improved, productivity strengthened and safety indicators moved in the right direction. The relevant lesson is institutional: technical leadership can create value when it gives the mine a clearer operating rhythm, stronger accountability and a single management logic. In a joint venture with two strong shareholder cultures, such integration requires leadership capable of applying shareholder standards without allowing the mine to become fragmented between different corporate centers.
That is the precedent Gómez brings to Codelco. The significance of his appointment lies in the role he is being asked to play: Codelco is appointing an executive whose public record is associated with recovery, integration and discipline inside a complex copper system. The question is whether that operating role can function inside a state owned company exposed to political visibility, public scrutiny, structural projects and institutional pressure.
The Codelco test
Codelco is not Collahuasi. Codelco is a different institution: older assets, structural projects, public ownership, fiscal pressure, political visibility, unions, parliamentary scrutiny and a national symbolic role. What worked in a private joint venture cannot simply be transplanted into a state owned enterprise. The underlying principle can travel: complex mining systems need integrated control, clear accountability and technical authority protected by competent governance. Codelco is a state owned enterprise, a national institution, a fiscal contributor, a political symbol and one of the most important copper producers in the world. Its decisions are watched by government, Congress, unions, communities, suppliers, investors, regulators, markets and citizens. That public role gives Codelco strategic weight. It also creates a permanent governance challenge: the company must remain technically focused while operating under intense political and public visibility.
Codelco now sits at the center of a broader institutional test. The company is no longer only a copper producer under operational pressure; it is becoming a measure of whether a state owned mining institution can protect technical judgment, operational truth and execution discipline under public visibility. Codelco needs strong supervision. It needs transparency. It needs accountability. It needs a demanding board, solid internal controls and public confidence. Recent events show why this matters. Codelco is not under scrutiny only because of production performance. It is under scrutiny because several dimensions of operational credibility have become visible at the same time.
One example is production recognition. On May 20, 2026, Codelco reported that an internal audit had detected deviations in the application of internal rules for production recognition. The case involved 20,000 metric tons of fine copper contained in oxides from Chuquicamata and 6,875 metric tons contained in calcium arsenite from Ministro Hales. Together, these amounts were equivalent to approximately 2% of Codelco’s own reported production for the year. The company said these materials required further processing and should have remained registered as work in process.
Another example is safety. The fatal accident at El Teniente in 2025 placed one of Codelco’s most important operations under intense public and institutional scrutiny. The purpose here is not to revisit the tragedy itself, but to situate it within a broader institutional question: how safety, geotechnical risk, contractor management, operational information and decision-making discipline are governed inside a state-owned mining company under public pressure.
Together, these examples move the discussion beyond copper output. For Codelco, the issue is the credibility of the systems that define what counts as production, how safety risks are escalated, how incentives are calculated, how technical information moves through the organization and how operational truth reaches the board, regulators and the public.Governance is the mechanism that protects that credibility. Good governance sets the mandate. It asks the right questions. It follows the right indicators. It protects safety. It monitors capital allocation. It ensures that incentives do not distort operational truth. It creates the conditions for management to execute.
In a mining company, governance must be technically literate. It must understand that production, safety, maintenance, projects, water, energy, tailings, sequencing, labor relations and communities are connected. Weakness in one part of the system can affect the entire operation. Gómez’s arrival does not solve Codelco’s problems by itself. It opens an institutional opportunity. Codelco can use this transition to strengthen operational discipline, restore confidence in control systems and give technical leadership a mandate with clear priorities, professional supervision and enough operating space to produce results.
The challenge for Chile is whether that distinction can hold. Technical leadership requires room to act, but it also requires serious accountability. If the new executive mandate is protected by competent governance, Codelco can use this transition to rebuild operational discipline. If the mandate is absorbed by political reaction, fragmented oversight or short-term pressure, the appointment will lose part of its strategic value. This is the institutional test behind the Gómez appointment: not whether Chile can name a technically strong executive, but whether it can create the conditions for that executive to govern complexity.
Supervision is not interference
State owned mining companies live under a different kind of pressure. They operate in public. They carry political symbolism. They are expected to generate revenue, sustain employment, execute large projects, manage communities, respond to national priorities and compete globally. Their leaders are often asked to explain technical decisions in political environments that do not always understand operational complexity. Codelco’s own governance model points in this direction. The company states that, under its corporate governance law, it is a company of the Chilean State administered by a nine-member board, and that the president and CEO is responsible for executing board agreements and supervising all productive, administrative and financial activities of the company.
A state owned mining company needs public accountability. It also needs enough institutional distance from the political cycle to protect technical judgment, long term planning and operational continuity. The board must supervise. The executive team must execute. When that boundary holds, governance strengthens the company. When it collapses, the mine begins to absorb political noise. Supervision clarifies priorities, protects the long term mandate, detects risk early and prevents distortion. Interference does something different. It multiplies noise. It turns operational decisions into political theater. It pressures executives to respond to the moment rather than to the mine. It disperses responsibility across too many actors and makes execution harder.
This is one of the central tests facing Codelco now. If Gómez is given a clear mandate, serious oversight and enough operational space, his technical profile can matter. If his role becomes trapped in political reaction, the appointment loses part of its value. The issue is whether supervision will be technically competent, institutionally mature and aligned with the long term performance of the company. The board’s role is to define priorities, protect the mandate, follow the right metrics and ask the right technical questions. The executive team’s role is to convert that mandate into operational discipline. When those roles are clear, governance strengthens the mine. When they become confused, strategic mining companies lose focus.
Patricio Hidalgo and the continuity question at Collahuasi
The other side of this transition is Collahuasi. Patricio Hidalgo’s appointment brings a strong mining profile and continuity with one of Collahuasi’s principal shareholders. Anglo American announced that Hidalgo, president of Anglo American in Chile, will become president and chief executive officer of Collahuasi from July 1, 2026. The company also highlighted Collahuasi’s status as an independently managed joint venture owned by Anglo American, Glencore and a Mitsui & Co.
His appointment creates a different governance question: stewardship. The issue is not Hidalgo’s technical capacity, but the institutional role he now assumes. His arrival reintroduces a familiar governance sensitivity for Collahuasi: how to preserve an independent, mine centered operating logic when the chief executive comes from one of the two principal shareholder groups. This matters because Collahuasi’s previous recovery cycle was associated with a shift away from a shareholder balancing executive model and toward a more market based, asset centered leadership structure. In that model, the chief executive’s role was not to extend one parent company’s operating culture, but to integrate shareholder standards, technical expectations and corporate disciplines into one coherent management system for the mine.
Hidalgo’s test, therefore, is whether he can preserve that independent operating logic while serving all shareholders, communities, workers and customers through a single management system. For a major joint venture, independence does not mean distance from shareholders. It means integration. It means transforming shareholder standards into one operating system that serves the mine. That requires a coherent operational rhythm across safety, productivity, sustainability, water, maintenance, sequencing, labor, communities and capital decisions, while managing two strong and distinct shareholder cultures and ensuring that the chief executive’s mandate is perceived as serving the asset as a whole, not one shareholder logic.
Collahuasi’s next stage is tied to C20+, the company’s infrastructure development and productive capacity improvement project. Collahuasi says C20+ includes a desalination plant that will deliver 1,050 liters per second, a water pumping system and transmission infrastructure to transport water by pipeline from the company’s port in Patache to the operation at 4,600 meters above sea level in Tarapacá. The permitting dimension is also active. On May 15, 2026, Chile’s Second Environmental Tribunal ordered a new analysis limited to the human baseline and marine environmental impacts of Collahuasi’s infrastructure and productive capacity improvement project. Anglo American later stated that, based on available information and existing alternative water sources, it did not expect an immediate impact on production, while Collahuasi sought clarity on the ruling from the Tribunal and the Environmental Assessment Service.
This makes the next leadership cycle at Collahuasi more demanding. The governance test is now both corporate and material. Collahuasi must preserve an independent operating logic among global shareholders while managing the physical systems that determine copper continuity: water, infrastructure, permitting, communities, marine impacts and execution discipline. Copper supply is becoming more strategic. Governments and markets often speak about copper as if supply could respond quickly to price signals or policy ambition. Mining works through longer, harder systems. Supply depends on assets that can be governed, expanded, permitted, financed, operated and sustained over time.
Technical governance as a strategic variable
Mining governance must understand the mine. A mine is a living technical system. It depends on geology, mine planning, processing, maintenance, tailings, water, energy, logistics, labor relations, environmental commitments, contractors, communities, permits, safety culture and capital allocation. These variables interact. They require governance with technical depth. Boards and executives do not need to operate the mine themselves. They need to understand what kind of questions a mine requires. They need to know when production targets are realistic. They need to detect when incentives create distortion. They need to distinguish between safety paperwork and real risk management. They need to know when maintenance is being postponed, when project timelines are losing credibility, when water or energy constraints are becoming strategic bottlenecks, and when public pressure is beginning to affect operational judgment.
This is the governance frontier of modern mining. In the age of critical minerals, governments increasingly speak about supply chains, industrial policy, national security and resource security. Those ambitions depend on a basic condition: mines must operate well. Mineral security requires operational discipline. Reliable supply requires technical governance. The Gómez-Hidalgo transition is a story about what modern copper institutions now require. Codelco needs an operator who can rebuild discipline inside a state owned system under pressure. Collahuasi needs a steward who can preserve independent operational logic while navigating growth, water and permitting complexity. Boards must protect the boundary between supervision and interference.
Strategic mining companies do not succeed because they have copper in the ground. They succeed when governance understands the mine well enough to turn complexity into reliable supply. In the age of geopolitical mining, that may become one of the most important competitive advantages of all.
