SANTIAGO, Chile — October 30, 2026. Chile’s state-owned copper producer Codelco has dismissed eight executives and professional staff as an investigation into inaccurate production reporting expands across several major mining divisions, raising fresh concerns about the reliability of output figures from one of the world’s most important copper suppliers.
The company announced the dismissals on October 29 following internal reviews and audits involving professional services firms KPMG and EY.
The affected employees worked at the Chuquicamata, Ministro Hales and Salvador divisions, as well as Codelco’s corporate headquarters.
The move follows earlier findings that some material requiring additional processing had been incorrectly recorded as completed copper production. Investigators are also examining whether the same material was counted by more than one mining division during 2024 and 2025.
The company has provided information to Chilean prosecutors and said further investigations and possible legal action remain under consideration.
But the implications extend far beyond a dispute over accounting procedures.
If one of the world’s largest copper producers cannot reliably measure and report its own output, investors and commodity markets face a difficult question: how much confidence should they place in its recovery targets?
Codelco confirms eight dismissals as investigation expands
In its October 29 announcement, Codelco said its board had reviewed additional information uncovered through internal audits and external investigations.
It decided to terminate the employment of eight people holding responsibilities across mining operations, mineral resource development, metallurgical accounting and corporate management.
The dismissals included senior personnel associated with the Salvador division and resource-development managers at several locations.
The company said the action was intended to strengthen corporate controls and preserve the integrity of information provided to shareholders, public authorities and the market.
But the dismissals do not establish that all eight employees committed criminal offenses.
The company has said investigations remain ongoing and that further responsibilities or legal consequences may be determined through appropriate procedures.
The distinction matters because an employment decision, an audit finding and a criminal conviction are different legal outcomes.
Which executives and officials were removed?
The dismissals affected positions with direct influence over mining operations and the recording of copper output.
Among those removed were the general manager of the Salvador division, the corporate manager of mining resources and development, and the equivalent resource-development managers at Chuquicamata, Ministro Hales and Salvador.
Also affected were the head of metallurgical valuation at corporate headquarters, Salvador’s smelter operations superintendent and the head of quality and metallurgical balance at Ministro Hales.
Reuters reported that Felipe Lagno would assume the general manager position at Salvador, replacing Patricio Viveros.
The range of positions involved is significant.
The investigation concerns not just production inside the mines but also the systems used to classify, reconcile and report mineral output.
For a large mining company, those systems influence management decisions, production targets and performance-based compensation.
An earlier audit uncovered nearly 27,000 tons of improper reporting
The latest controversy builds on findings Codelco disclosed in May.
That earlier investigation identified 20,000 metric tons of fine copper contained in oxide material at Chuquicamata and 6,875 metric tons contained in calcium arsenite material at Ministro Hales.
Together, the quantities totaled 26,875 metric tons, equivalent to approximately 2% of the company’s reported own-mine copper production for 2025.
Codelco said the materials still required processing and did not fully satisfy internal requirements to be classified as finished products.
They should instead have remained recorded as work in progress.
The company identified failures involving the application of reporting rules, approval requirements and the use of exceptions.
Codelco dismissed one executive and imposed disciplinary measures on other personnel following that review.
It also instructed management to recalculate performance incentives affected by the production figures and pursue recovery where appropriate.
Importantly, the company said the May findings did not require changes to its audited financial statements for 2025.
That statement relates to the earlier audit. It should not be treated as a final conclusion about every subsequent issue now under investigation.
October investigation reveals possible double counting between divisions
A further development emerged on October 6.
Codelco disclosed preliminary evidence indicating that material may have been registered as production by more than one division.
The newly identified discrepancies involved Ministro Hales and Salvador and potentially affected the production figures reported for 2024 and 2025.
The company said the same material appeared to have been recorded by multiple divisions.
If confirmed, that would represent a separate reporting problem from the earlier classification of unfinished material as completed production.
Codelco asked EY to carry out an independent external investigation to establish the scope of the discrepancies, their causes and any economic effects.
It also submitted information to Chile’s Public Prosecutor’s Office.
The precise amount of duplicated production had not been established in the reviewed October 29 disclosures.
It would therefore be misleading to claim that the newly identified issue has already been quantified or to add an invented tonnage to the earlier 26,875-ton finding.
Why Codelco’s copper production figures matter worldwide
Codelco is among the world’s largest copper producers.
Its output helps supply international manufacturing industries that depend on the metal for electrical systems, construction, vehicles, industrial machinery and renewable-energy infrastructure.
Copper is essential for conducting electricity, making it an important material in power grids, electric vehicles and data centers.
Because Chile is a major international copper supplier, changes in production expectations can influence market assessments of future availability.
However, inaccurate reporting at one company does not automatically mean that the same number of tons disappeared from global physical inventories.
The audit concerns how production was classified and recorded.
The effects on saleable supply, inventories and previously reported financial results must be determined through the ongoing reviews.
For commodity traders, the concern is the reliability of information used to understand mine output and supply trends.
An extraordinary December production surge raised early questions
Questions about Codelco’s output began growing earlier in 2026.
Reuters reported in March that the miner produced approximately 172,300 metric tons of copper during December 2025, an unusually strong month that helped the company reach its annual production target.
But January 2026 production fell to approximately 91,000 metric tons.
That was a 47% decline from December and about 1.8% lower than January a year earlier.
Codelco initially attributed its December performance to factors including the processing of accumulated material, improved ore grades and operational gains at certain divisions.
Industry specialists nevertheless questioned whether the end-of-year increase was sustainable and whether the figures reflected material that met the company’s production-recognition standards.
The subsequent audit findings gave those questions greater significance.
Still, the sharp month-to-month decline should not be treated as proof that every ton of December production was invalid.
Mining output can vary because of maintenance, ore quality, processing schedules and operational disruptions.
The production scandal complicates Codelco’s turnaround plan
Codelco has been trying to recover from years of declining output and rising production costs.
In 2022 and 2023, its production dropped to levels not seen in decades.
The company subsequently reported around 1.33 million metric tons of copper production from its own mines for 2025, although the accounting concerns complicate interpretation of that headline.
Codelco previously pursued a goal of reaching approximately 1.7 million metric tons annually by 2030.
But newer management assessments have suggested production could remain closer to 1.3 million metric tons for the next several years.
The company is also reviewing its organizational structure, operating costs and future investment strategy.
Reuters reported in September that Codelco’s restructuring plan could be delayed until the end of 2026.
The production-reporting controversy increases the pressure on management to demonstrate that future targets are based on dependable operating data.
A recovery plan is only as credible as the information used to create it.
Potential workforce reductions add another complication
Codelco’s organizational review could have significant consequences for workers and contractors.
Reuters reported that people familiar with the restructuring discussions had suggested potential workforce reductions ranging from 5% to 20%.
Codelco cautioned that no final decisions had been made and that speculation about precise staffing changes was premature.
The company has a large workforce, much of it employed through contractors.
Any substantial restructuring could therefore affect mining communities and local economies.
The latest eight dismissals should not be confused with a finalized companywide layoff plan.
They were specifically linked to the production-reporting investigation.
The broader restructuring remains a separate management process, although both developments are influencing questions about corporate governance and operational performance.
Copper markets are already dealing with unusual supply pressures
The Codelco investigation comes during a volatile period for international copper trading.
Manufacturers need copper for infrastructure and technology, while trade-policy uncertainty has encouraged large movements of physical metal between markets.
WWC ONE MEDIA previously explored this issue in $500 Million Copper Shipment Heads to New Orleans as Port Nears Capacity — But the Bigger Problem May Be Just Beginning.
That report examined how tariff expectations encouraged traders to redirect copper toward the United States, placing pressure on storage and transportation infrastructure.
The situation is different from Codelco’s accounting investigation.
Nevertheless, both developments illustrate why copper-market participants need reliable information about production, available inventories and physical deliveries.
A strong price signal does not always indicate a straightforward global shortage, just as an overstated production figure does not automatically establish a matching physical loss of metal.
Corporate governance is now at the center of the mining debate
Codelco’s latest dismissals illustrate the importance of internal reporting controls in industries where large quantities of material move through complex production processes.
Copper may be mined, crushed, concentrated, smelted and refined through different operations.
Companies need clear standards for determining when material qualifies as finished production and when it should remain classified as work in progress.
Failure to apply those rules consistently can distort operational performance.
It can also affect executive incentives when bonuses or management targets are linked to reported output.
Corporate governance is an important issue for mining companies in the Philippines as well.
WWC ONE MEDIA recently examined oversight in DMCI Group Bags Seven Golden Arrows as First-Half Profit Rises 26% — But Can the Consunji-Led Conglomerate Sustain Its Governance Record?.
That article discussed governance recognition involving DMCI Holdings and Semirara Mining and Power Corporation.
It is not connected to Codelco’s investigation.
The broader lesson is that governance awards, internal controls and transparency standards must be judged alongside actual compliance and independently verified performance.
What the controversy means for Philippine mining
The Philippines also produces copper and other minerals important to global technology and manufacturing.
The country’s mining industry is attempting to increase domestic value addition while facing continuing questions about environmental protection, community benefits and regulation.
WWC ONE MEDIA explored these issues in Philippine Mining Under Scrutiny: Can Damaged Landscapes Become Thriving Communities Again — Or Are the Environmental Costs Too High?.
The article examined how mining operators should be assessed through measurable environmental results and long-term community outcomes.
Although the Chilean investigation concerns production accounting rather than mine rehabilitation, both issues involve the public’s ability to rely on information reported by mining companies.
Accurate production data, transparent financial reporting and credible environmental monitoring all contribute to accountability.
The lesson is especially relevant when governments are encouraging more investment in critical minerals.
Philippine copper projects also face financial and legal scrutiny
Copper projects can require substantial financing and long development periods before reaching commercial production.
Disputes over ownership, lending and project obligations can create additional uncertainty.
WWC ONE MEDIA previously reported on Celsius Faces Court Setback as ₱1.5-Billion Kalinga Mining Stake Heads Toward Auction — But the Legal Fight Is Far From Over.
That dispute involves a Philippine copper-gold project and is unrelated to Codelco’s production-reporting case.
But it illustrates how investors must examine legal arrangements, financing and governance rather than focusing only on a project’s estimated mineral resources.
For both Chilean and Philippine mining operations, credible public disclosures are essential to sustaining investor confidence.
What happens next in the Codelco investigation?
The next stage will depend on the findings of the ongoing internal and external audits.
Investigators must determine whether additional production was counted more than once, how the discrepancies occurred and which reporting controls failed.
They will also need to assess whether the issues affected inventories, performance incentives or financial results.
Chile’s prosecutors may determine whether any conduct warrants criminal proceedings.
Codelco has indicated that it may pursue legal remedies to protect its interests.
For investors and the public, several questions remain unanswered.
The final size of the newly identified discrepancies has not been established.
The financial consequences remain under review.
And any further personnel or disciplinary decisions will depend on the outcome of the investigations.
The company has committed to providing additional information as the process continues.
The bigger question: Can Codelco rebuild trust in its numbers?
Codelco is confronting two major challenges simultaneously.
It needs to improve mine production after a prolonged slump.
And it must demonstrate that the figures used to judge that recovery are accurate.
The dismissal of eight more staff members shows that management is taking further action in response to the investigation.
But changing personnel does not, by itself, solve the underlying reporting problem.
The company still needs clear accounting standards, effective internal controls, independent verification and transparent corrections where necessary.
The investigation could also influence how investors assess future output forecasts and management targets.
For Chile, the stakes are especially high because copper remains a critical industry and Codelco is a major state-owned enterprise.
For global markets, reliable production information is essential at a time when copper demand is being reshaped by electrification, infrastructure and changing trade policies.
Codelco has dismissed eight more employees as its copper-reporting investigation expands. But the decisive test is still ahead: can the company establish exactly how much output was misreported, hold the responsible parties accountable and rebuild confidence in its production targets before the controversy further undermines its turnaround?
