TitleChief Executive Officer, Antofagasta plc

Iván Dagoberto Arriagada Herrera (born October 1963) is a Chilean business executive who has been chief executive officer of Antofagasta plc, the London-listed, Chile-focused copper mining group controlled by the Luksic family, since April 8, 2016.[1][2][3] Before that he ran the group's mining division, Antofagasta Minerals, from February 2015, and between 2012 and 2014 he was vice president of administration and finance, the chief financial officer role, at the Chilean state copper company Codelco.[2][4]

Arriagada trained as a commercial (business) engineer in Chile and took a master's degree at the London School of Economics. He worked for Shell in Chile, the United Kingdom, Argentina and the United States between 1987 and 2005, and then moved into copper mining with BHP Billiton's Base Metals business. There he held finance and operating posts, among them chief financial officer of the division, and was president of its Pampa Norte unit, which ran the Spence and Cerro Colorado mines.[4][1]

As chief executive, Arriagada has overseen the expansion of Los Pelambres, including a desalination plant, the approval and construction of a $4.4 billion second concentrator at Centinela, the group's exit from the Reko Diq project in Pakistan, and the purchase of a stake of about 19 percent in the Peruvian miner Compañía de Minas Buenaventura.[5][6][7][1] Antofagasta's revenue went from $3.6 billion in 2016, his first year in charge, to $8.6 billion in 2025, a year in which EBITDA reached a record $5.2 billion.[8][9]

Outside the company, Arriagada chaired the International Council on Mining and Metals (ICMM) from 2022 to 2024. The council's members elected him chair again on December 11, 2025, for a two-year term.[10] He is also a director of Buenaventura and a former president of the International Copper Association.[11] As of October 2026 he remains chief executive of Antofagasta, and he was quoted in that role in the company's third-quarter production report on October 15, 2026.[12]

Early life and education

UK Companies House records give Arriagada's date of birth as October 1963, his nationality as Chilean and his country of residence as Chile.[3] Antofagasta gave his age as 52 when it announced his appointment as group chief executive in April 2016.[2]

He studied at the Escuela de Negocios of the Universidad Adolfo Ibáñez, which the 2016 appointment notice described as part of the Universidad Federico Santa María, and graduated as an ingeniero comercial (commercial or business engineer).[2][4] Antofagasta has described him as a "commercial engineer and economist".[13] He then took a Master of Science at the London School of Economics and Political Science; the 2016 Antofagasta announcement gives the subject as finance.[2][4] He has also attended executive education programmes at the Wharton School, INSEAD and the MIT Sloan School of Management.[2]

Career

Shell (1987 to 2005)

Arriagada began his career in the oil and gas industry with Shell. Codelco's 2012 announcement of his appointment states that he worked for Shell between 1987 and 2005, in Chile, the United Kingdom, Argentina and the United States.[4] Antofagasta's biographies describe more than 15 years at Shell with "senior assignments" in those four countries, and the 2016 appointment notice puts the figure at almost 20 years.[1][2] Buenaventura's annual report says he spent "a large part of his career" at Royal Dutch Shell International before moving into copper mining.[11] The published sources do not list the individual posts he held at Shell.

BHP Billiton (2005 to 2012)

In 2005 Arriagada joined BHP Billiton's Base Metals division, its copper business. According to Codelco he held posts there that included vice president of finance, chief financial officer, interim president, and vice president of operations for Australia, Peru and the United States.[4] Antofagasta's 2025 annual report describes these as "various positions over eight years at BHP Base Metals", including vice president of operations and chief financial officer of the division.[1] Filings that BHP Billiton made with the US Securities and Exchange Commission in early 2007 list an "Ivan Arriagada" as an investor relations contact, with London and South African telephone numbers and the e-mail address [email protected].[14]

From October 2011 he was president of Pampa Norte, the BHP Billiton unit that operated the Spence and Cerro Colorado copper mines in northern Chile.[4] He held that post during a BHP Billiton Base Metals investor site tour of Spence on September 30, 2012.[15]

Codelco (2012 to 2014)

On October 8, 2012, Codelco informed Chile's securities regulator, the Superintendencia de Valores y Seguros, that it had appointed Arriagada vice president of administration and finance, with effect from November 19, 2012. He filled the vacancy left by Thomas Keller, who had become Codelco's executive president.[4] Antofagasta's biographies list the post as chief financial officer of Codelco.[13]

On November 11, 2014, Codelco told the regulator that Arriagada had resigned voluntarily "to take on new professional challenges", with effect from December 15, 2014. Executive President Nelson Pizarro thanked him for "a little more than two years" at the company and singled out his work on Codelco's capitalisation and on putting in place its structural productivity and cost programme.[16]

Antofagasta Minerals (2015 to 2016)

Arriagada joined the group in 2015 and became chief executive of Antofagasta Minerals, the group's mining division, in February of that year.[2] At the same time his predecessor in that job, Diego Hernández, moved up to run the parent company.[17] The company's 2015 annual report states that the mining division was "managed by the Antofagasta Minerals Executive Committee under the leadership of Iván Arriagada", while Hernández as group chief executive led the senior management team.[13]

His year at the head of the mining division came during a sharp fall in copper prices. In its announcement of his promotion, the company said that Arriagada had "led a rigorous cost reduction programme" aimed at keeping the balance sheet sound and making sure every operation generated operating cash flow at prevailing copper prices.[2] In December 2015 the group bought a 50 percent interest in the Zaldívar copper mine from Barrick Gold for a total consideration of $1,005 million and took over as operator. In the same year the Antucoya mine, which the company called the only new mine opened in Chile that year, was completed.[13]

Chief executive of Antofagasta plc (2016 to present)

Appointment

On April 8, 2016, Antofagasta announced that Hernández was retiring as chief executive with immediate effect and that Arriagada would succeed him. Hernández stayed on as an adviser to the board.[2] Chairman Jean-Paul Luksic said that Arriagada was "the right person to succeed Diego" and that his leadership had "proven effective to navigate the current challenges of low copper prices without losing our ability to grow and develop in the future". Arriagada said that he was "proud to be taking on the role of CEO of the Company".[2] Analysts at Barclays wrote that he was "already well respected by the market", and that afternoon the shares were trading 1.3 percent higher at 432.6 pence.[18] The company's remuneration committee later described the appointment as an internal one, made under the group's succession plan.[8]

Arriagada is not a member of Antofagasta's board. The company explains this as reflecting "the law and practice in Chile": the board is made up only of non-executive directors, and the chief executive attends meetings, chairs the Executive Committee and is responsible for carrying out the strategy the board sets.[1][8]

Downturn and portfolio changes (2016 to 2018)

In the company's 2016 annual report Arriagada described his first year as one of "putting people and safety first, focusing on improving our operating efficiency and rebasing our cost structure". He listed the start-up of Antucoya, the integration of Zaldívar and the sale of Michilla, the group's first operating mine, as the main structural changes to the portfolio.[8] Michilla was sold to Haldeman Mining Company at the end of 2016.[8] The group produced 709,400 tonnes of copper that year.[8] Also in 2016, the company reached a settlement with the Caimanes community near Los Pelambres that resolved two court cases over the El Mauro tailings dam (see Controversies and disputes).[8] Two fatal accidents in 2016, at Antucoya in April and in the transport division in July, led Arriagada to write that "it is not acceptable that we still have" such accidents.[8]

Over 2017 and 2018 Arriagada sold non-core assets and put the capital back into copper or returned it to shareholders. The group sold its interest in the Alto Maipo hydroelectric project in 2017, then its electricity transmission lines at Centinela for $117 million in July 2018 and its holding in the El Arrayán wind farm for $28 million in August 2018.[5] In 2018 Antofagasta produced a record 725,300 tonnes of copper, at net cash costs of $1.29 per pound, and reported EBITDA of $2,228 million, a margin of 47 percent. In his annual letter Arriagada attributed 10 cents per pound of savings, equivalent to $184 million, to the group's Cost and Competitiveness Programme.[5]

Los Pelambres expansion and the purpose statement (2018 to 2019)

In November 2018 the board approved the expansion of Los Pelambres. At a cost of $1.3 billion, including a $500 million desalination plant, the project was meant to raise plant throughput from 175,000 to 190,000 tonnes of ore a day and add an average of 60,000 tonnes of copper a year over 15 years. Arriagada wrote that the company had used the downturn to advance detailed engineering and secure better terms from suppliers, and that it would finance the whole project with debt rather than from cash flow.[5]

During the 2018 strategy review with the board, the company adopted the purpose statement "Developing Mining for a Better Future". Arriagada said it reflected the idea that "as a business organisation, we work to be a cause for good in wider society".[5]

COVID-19 pandemic (2020)

In 2020 the group produced 733,900 tonnes of copper, 4.7 percent less than its 2019 record, at net cash costs of $1.14 per pound. Work on projects including the Los Pelambres expansion was halted for part of the year to protect workers.[19] Antofagasta set up a $6 million fund to support communities near its operations and issued its first corporate bond. After the pandemic it permanently adopted a mix of remote and in-person work for office-based staff, a model Arriagada said would make the organisation more resilient and help employees balance work and home.[19] In October 2020 the board approved a climate change strategy.[19]

Drought, Reko Diq and Twin Metals (2021 to 2022)

The group's production fell to 646,200 tonnes in 2022, 10 percent below 2021, mainly because drought in central Chile limited water and so throughput at Los Pelambres, and because of planned lower grades at Centinela. Net cash costs rose to $1.61 per pound from $1.20 per pound.[7] In 2022 Antofagasta completed the switch of all its operations to electricity supplied under renewable-source contracts. That process had begun at Zaldívar in July 2020 and ended at Los Pelambres in April 2022.[7]

In 2022, under Arriagada, the group also left the Reko Diq copper and gold project in Pakistan. It had held the project equally with Barrick Gold through Tethyan Copper Company, and work there had stopped a decade earlier (see Major deals and strategic decisions).[7] In January 2022 the US Department of the Interior cancelled two federal mineral leases held by Antofagasta's Minnesota subsidiary Twin Metals. Arriagada wrote that the company was challenging the decision and still regarded the project as "world-class".[7]

Centinela, Buenaventura and growth projects (2023 to present)

In 2023 the first phase of the Los Pelambres Expansion, which Arriagada described as "a $2 billion investment", was completed, and the desalination plant came into operation.[6] In his letter for that year he reported the approval of the Centinela Second Concentrator Project, a $4.4 billion investment expected to employ nearly 13,000 people at the peak of construction.[6] In its 2022 report the company had said the decision on Centinela depended on "greater clarity" about the mining royalty and tax bills before the Chilean Congress and on the process of drafting a new constitution.[7]

In December 2023 the group, through a subsidiary called Andean LFMA Investment Limited, revealed a large holding in Compañía de Minas Buenaventura, Peru's largest listed precious and base metals miner. Arriagada signed the US regulatory filing as Antofagasta's chief executive.[20] He joined Buenaventura's board in 2024 (see Board memberships and outside roles).[11]

For 2025 the company reported revenue of $8.6 billion, 30 percent more than in 2024, and record EBITDA of $5.2 billion, a margin of 60 percent. The group invested $3.7 billion during the year, and its board recommended a final dividend of 48 cents per share.[9] Arriagada said that the Centinela and Los Pelambres projects were "on time and on budget" and that peak group capital expenditure for the current projects had passed in 2025, which put the company "on track to deliver 30% growth in production over the medium term".[9] In his 2025 letter he wrote that women made up 30 percent of the workforce.[1]

In July 2026 heavy rain and power cuts forced a controlled shutdown of Los Pelambres, beginning late on July 18. The company reported no safety incidents, and operations restarted within days.[21] In the half-year results, published on August 13, 2026, Arriagada said that the restart had "progressed in a safe and orderly manner". He also said the company had approved investment to move Zaldívar away from continental water sources, which could allow the mine's life to be extended to 2051.[22] In the third-quarter production report of October 15, 2026, he said that the Centinela and Los Pelambres projects had "entered the final phases of each schedule", with construction and commissioning due to finish in 2027. He also gave production guidance for 2027 of 630,000 to 690,000 tonnes of copper.[12]

Leadership and management style

The company's remuneration reports set out how its board has judged Arriagada's performance. For 2025 the remuneration committee rated his performance against his personal objectives at 100 percent of maximum. Its summary credited him with "transparent, proactive and consistent communication with the Board" and "visible and values-based leadership". It also said he had led a restructuring of the Executive Committee and senior leadership "promoting internal capability while selectively attracting external expertise".[1] The same report states that he "contributed significantly to reinforcing and stabilising relationships with communities, authorities and government stakeholders".[1]

In his shareholder letters Arriagada has repeatedly put safety first. After a contractor died at Los Pelambres in October 2018, ending a run of more than two years without a fatality, he wrote that "a fatality free environment is possible" and was "an absolute imperative".[5] In 2020 he reported 27 months without a fatality.[19] He has also stressed cost control, digital technology and innovation. These included a $40 million budget for the group's technology platform, remote operations centres for Centinela and Los Pelambres, autonomous haulage trucks at Centinela, and the company's patented Cuprochlor-T leaching process for primary sulphide ores.[5][19][7]

On workforce diversity, Arriagada wrote in 2018 that improving diversity was "one of my current focuses" and that the company had joined the 30% Club, which campaigns for gender balance.[5] He reported female representation of 23.6 percent in 2023 and 30 percent by 2025, against a target of 30 percent by the end of 2025.[6][1] He has also described the climate crisis as "the greatest environmental emergency of our times". He has backed the company's target of carbon neutrality by 2050 at the latest and its shift to sea water and recirculated water at its mines.[7]

Major deals and strategic decisions

  • Zaldívar (December 2015). While Arriagada was chief executive of Antofagasta Minerals, the group bought 50 percent of the Zaldívar mine from Barrick Gold for $1,005 million and became its operator.[13]
  • Michilla (2016). The group sold Minera Michilla, its first operating mine and its highest-cost operation, to Haldeman Mining Company.[8]
  • Non-core disposals (2017 to 2018). It sold its interest in the Alto Maipo hydroelectric project in 2017, then the Centinela transmission lines for $117 million and the El Arrayán wind farm stake for $28 million in 2018.[5]
  • Los Pelambres expansion (approved November 2018). A $1.3 billion project including a $500 million desalination plant, funded entirely with debt. The completed first phase was later described as a $2 billion investment.[5][6]
  • First bond issue (2020). Under Arriagada the company issued its first bond, entering the debt capital markets to diversify its funding.[19] By 2025 it had issued its fourth corporate bond.[1]
  • Reko Diq exit (2022). In 2019 the World Bank's International Centre for Settlement of Investment Disputes awarded $5.84 billion in damages to Tethyan Copper Company after Pakistan denied the project a mining lease in 2011. In March 2022 the parties agreed a framework under which the project would be reconstituted and Antofagasta would exit. Under definitive agreements signed in December 2022, the award was resolved and Antofagasta was to receive proceeds of $946 million. It recognised an exceptional gain of $945 million in 2022.[7]
  • Centinela Second Concentrator (approved 2023). A $4.4 billion project, which Arriagada wrote would add about 170,000 tonnes a year of copper-equivalent production, with construction due to finish in 2027.[6][1]
  • Buenaventura (December 2023 onward). In December 2023 the group's subsidiary Andean LFMA held about 7.1 percent of Buenaventura's shares directly. It had also arranged for a further 11.8 percent to be delivered under a contingent share purchase agreement with a dealer.[20] By the end of 2025 the group held an 18.94 percent interest, which it treats as an associate.[1]
  • Zaldívar water transition (2026). The group approved investment to replace continental water at Zaldívar, opening the way to a possible extension of the mine's life to 2051.[22]

Sources: annual reports for 2016,[8] 2018,[5] 2020,[19] 2022,[7] 2023[6] and 2025.[1]

Copper production was 709,400 tonnes in 2016, a record 725,300 tonnes in 2018, 733,900 tonnes in 2020, 646,200 tonnes in 2022, 660,600 tonnes in 2023, 664,000 tonnes in 2024 and 653,700 tonnes in 2025.[8][5][19][7][6][1]

EBITDA was $2,228 million in 2018, a margin of 47 percent, and a record $5.2 billion in 2025, a margin of 60 percent. Net debt was 0.53 times EBITDA at the end of 2025.[5][9] For the first half of 2026 the company reported revenue of $4,479.0 million, up 18 percent, and EBITDA of $2,840.5 million, up 27 percent, a margin of 63.4 percent.[22] Production for the first nine months of 2026 was 436,900 tonnes, 8 percent lower than a year earlier, mainly because of lower grades at Centinela Concentrates and lower recoveries at Centinela Cathodes.[12]

Remuneration

The company voluntarily publishes Arriagada's pay. His total single-figure remuneration, in thousands of US dollars, was 681 for part of 2016 (from April 8), 1,790 in 2017, 2,513 in 2018, 2,458 in 2019, 4,675 in 2020, 4,134 in 2021, 5,292 in 2022, 5,046 in 2023, 5,561 in 2024 and 8,698 in 2025.[1] The 2025 total was made up of a salary of $1.324 million, benefits of $136,000, an annual bonus of $2.374 million (84.3 percent of the maximum), restricted awards of $1.216 million and performance awards of $3.647 million. According to the report, $1.8276 million of the performance award came from the rise in the share price over the performance period.[1]

He is employed by the Chilean subsidiary Antofagasta Minerals S.A. under a contract governed by Chilean labour law. The contract has no fixed term and can be ended by either side on six months' notice. His salary is paid in Chilean pesos, adjusted for inflation every quarter, with a further adjustment if the peso weakens by more than 5 percent against the US dollar.[1] His long-term incentive awards are phantom shares settled in cash. According to the company, he holds no shares in Antofagasta, and it makes no pension contributions on his behalf.[1]

Board memberships and outside roles

  • International Council on Mining and Metals. Companies House records show Arriagada as a director of The International Council on Mining and Metals Limited since April 8, 2016.[3] He chaired the ICMM from 2022 to 2024. On December 11, 2025, he was elected chair again for a two-year term, succeeding Tom Palmer of Newmont. ICMM President Rohitesh Dhawan said that Arriagada's earlier term had made progress on the Global Industry Standard on Tailings Management and started work on the Consolidated Mining Standard Initiative.[10][23] Antofagasta reported in 2023 that its main tailings facilities at El Mauro and Centinela fully complied with that standard.[6]
  • Compañía de Minas Buenaventura. Arriagada joined Buenaventura's board in 2024, with a term running to March 2029. In 2025 he sat on its compensation committee. He is entitled to director's fees from Buenaventura, which fall outside the remuneration Antofagasta reports for him.[11][1]
  • International Copper Association. Buenaventura's annual report states that he was formerly president of the International Copper Association.[11]
  • Within the group, Arriagada chairs the Executive Committee.[1]

Controversies and disputes

Caimanes and the El Mauro tailings dam

Los Pelambres' El Mauro tailings dam had been the subject of long litigation with the nearby community of Caimanes. In April 2016, the month Arriagada became group chief executive, Antofagasta reached an agreement with the community that resolved two court cases concerning the dam. Chairman Jean-Paul Luksic called it the start of "a new era of community engagement" for Los Pelambres.[8] Arriagada wrote that the company was going ahead with the plans agreed with the community and the courts on future water supply, additional safety measures and community development.[8] Press coverage at the time of his appointment noted that protesters worried about water shortages had disrupted operations around Los Pelambres.[17]

Twin Metals

Twin Metals Minnesota, a subsidiary of the group, is developing a copper, nickel and platinum group metals project in north-eastern Minnesota. In 2019 it renewed two federal mining leases for the project.[7][6] In January 2022 the Department of the Interior cancelled federal mining leases 1352 and 1353; in 2021 and 2022 federal agencies also rejected the company's preference right lease applications and its mine plan of operation. Antofagasta wrote off the full $150.1 million carrying value of Twin Metals' mining licence assets at the end of 2021.[7][1] Twin Metals sued in the US District Court for the District of Columbia, arguing that the government's actions were "arbitrary and capricious". The court dismissed the claims in September 2023, and the company appealed in November 2023.[6] In its 2025 annual report Antofagasta said that Twin Metals believed it held a valid legal right to the leases, but that the project as configured remained on hold while the litigation continued.[1]

Chilean royalty and constitutional debates

Between 2021 and 2023 Chile debated a new mining royalty and a rewrite of its constitution after the 2019 protests, and the mining industry sought "stability" in the new constitutional text.[24] Under Arriagada, the company made the timing of its largest investment, the Centinela second concentrator, depend on "greater clarity" about those bills and the constitutional process.[7]

Recognition

In its 2025 assessment of Arriagada, the company's remuneration committee recorded that the board recognised him "for authenticity, commitment and disciplined execution".[1] His election as ICMM chair, a post chosen from among the chief executives of its 26 member companies, is the main external recognition recorded in the sources.[10]
