Policy influence

Largest Contributions & Expenditures

Lobbying and Trade associations

As members of the ICMM, we adhere to their principles. Climate change is one of the most critical global challenges of our time. Therefore, ICMM acts in line with the goals of the Paris Agreement to achieve the Sustainable Development Goals, recognising the interconnected nature of climate change, water, biodiversity, and socio-economic development. This integrated approach is central to ICMM's Mining Principles, reflecting its longstanding commitment to responsible mining and enhancing the contribution of minerals and metals to sustainable development.

As a company that complies with ICMM principles, we ensure that we do not lobby against the Paris Agreement or engage with trade associations that fail to comply with it. In Chile, ties with governments and regulators are subject to strict engagement mechanisms, defined under Lobby Law No. 20,730. This Law regulates lobbying activity and other efforts to represent specific interests to support greater transparency.

We comply with our own policies and the laws and regulations of host countries, always maintaining high engagement standards. Our lobby activities follow the law, and their purpose is to present the Group's projects to the authorities. These projects comply with our own social and environmental policies, climate change strategy, and commitments that are aligned with the Paris Agreement, such as emissions reduction and carbon neutrality by 2050, reduction of continental water withdrawal, and active community engagement.

Wellbeing

Employee Support Programmes

Antofagasta PLC complies with Chilean law, which gives parents the right to parental leave. Mothers have 18 weeks of paid parental leave, which is divided into 6 weeks pre-birth and 12 weeks after birth. Fathers have 1 week after birth.

Living wage commitment

At Antofagasta plc, we are committed to paying ethical wages (AKA living wages) to 100% of our employees and contractors, which, as of December 2023, were 35% higher than the Chilean legal minimum. We also provide benefits such as life and health insurance.

The ethical wage refers to a wage or income level that is sufficient to provide for a person’s basic needs and a decent standard of living, which is higher than the minimum wage, considering basic expenses like housing, food, clothing, education, healthcare and transportation.

Living wage methodology

In 2007, the group adopted the living wage criterion based on good public practices from think tanks, NGOs, and the Centro de Estudios CEP (which uses studies that calculate the living wage based on the minimum income necessary for a worker to meet their basic needs, which include necessities such as food, housing, healthcare, education, transportation, and clothing, among others). It is a concept of guaranteed fixed monthly remuneration (excludes any fixed and/or variable bonus), plus life insurance and supplementary health insurance.

Every January, the minimum living wage is reviewed and updated in conjunction with the Procurement area, after which the different companies are informed about its application. In the last two years, it has been between 50% and 55% above the national minimum wage increase and in line with the CPI increase.

Diversity

Talent Development, Retention and Attraction

At Antofagasta, we seek to strengthen human capital and talent at our Company and in the local communities where we focus our recruitment efforts. We strive to provide the proper tools to enable our employees to develop their full and diverse potential, delivering innovative solutions to multiple challenges, and to support the digital transformation of our business.

Employee Development Programmes

Female Leadership Programme:

Antofagasta Minerals' Women's Leadership Programme aims to leverage the development and promotion of women within the organisation and, through a series of strategic initiatives, seeks to create an inclusive and equitable environment in which women can develop their management skills and reach their full potential. The initiatives include:

1. Mentoring: An initiative in which mentors and mentees from the Group participated to create an environment where women can thrive, grow and reach their full potential, promoting their professional development and strengthening their leadership through guidance, feedback and opportunities for advancement.
2. Promociona: Initiative that increases the presence of women in management positions in companies, promoting shared and inclusive leadership.
3. BOW (Board of Women): is an initiative that seeks to train high-potential women professionals in management skills.
4. WoomUP: Inter-company mentoring programme where mentors and mentees from different companies collaborate for mutual development.
5. Leadership for managers: Initiative that promotes leadership for women, focused on female executives and their managers.
6. Mentoring with Comunidad Mujer: Accompaniment of women in the Mining Group by the Comunidad Mujer organisation, empowering female talent within their teams.
7. WIM (Woman in Mining): Certification of directors with the Women in Mining organisation in collaboration with Adolfo Ibañez University.

The objective of the Women's Leadership Programme is to enable women to assume leadership roles within the Antofagasta Minerals Group, fostering an environment that recognises and values female talent.

It seeks to enhance their capabilities, offer growth opportunities and strengthen their positioning in the Group, contributing to developing a more diverse and inclusive work environment.

This comprehensive approach benefits not only the women participants in terms of internal mobility or promotion but also all Antofagasta Minerals employees since promoting diversity and inclusion improves the commitment of the teams and enriches the organisational culture. It allows variety within teams, which provides ideas and solutions, improves decision-making, and fosters creativity.

Through these types of programmes, we can achieve an inclusive environment that contributes to the safety and well-being of all and reinforces our commitment to social responsibility.

In total, 70 women (9% of FTE) actively participated in at least one of the above-mentioned initiatives:

• 30 women obtained internal mobility (lateral or promotion), representing 43% of the total programme participation.
• 24 women upgraded their performance during the year they received training (34% of total programme participation).
• 21 people obtained a salary band change (30% of total programme participation).

In general, this programme does not directly impact the business KPIs, but the percentages shown do impact engagement, talent retention, internal mobility, talent attraction, and employer branding.

Maintenance Training

In 2023, Antofagasta Minerals worked on Maintenance Training, an initiative that includes two programmes: one exclusively for the maintenance area, the Maintenance Leaders Programme, and a second called Shift Supervisors Programme, aimed at different critical operational areas, including Maintenance.

The first initiative is aimed at Superintendents and Senior Engineers in the areas of Execution, Reliability and Maintenance Planning (executive and supervisory roles). It seeks to encourage participants to empower, train and enable a new maintenance culture, promoting excellence, commitment and a sense of belonging to the Antofagasta Minerals Group. This initiative contains modules related to personal leadership, teamwork, maintenance management, change management, negotiation, communication and psychological safety, and integration of learning.

The second initiative is aimed at Shift Supervisors (supervisory role) and seeks to empower them since they are the direct line of the organisation to operators. They are key enablers of the Operating Model, which will leverage the execution of the Group's strategy. This initiative contains modules related to leadership, people management, labour relations, key competencies, and knowledge that allow them to act as an effective link between management and operators and facilitate their empowerment and team management.

The Maintenance Training aims to strengthen and develop leadership, technical, and management competencies in the key roles in this area for each of our companies. Through a series of training modules, this programme is designed to ensure that executives and maintenance shift managers develop the necessary skills to improve operational efficiency, promote a safe and collaborative work environment, and effectively lead teams.

Implementing Maintenance Training benefits the Mining Group by improving operational efficiency through the standardisation of criteria, practices, and knowledge in all the Group's operations. This ensures more efficient and coordinated maintenance management, thus strengthening the "Safety and Sustainability" strategic pillar.

This training also fosters innovation and adaptability by training leaders to manage tensions and resistance, facilitating the adoption of new practices and work habits, supporting the Innovation pillar.

In total, there were 15 people participated in the Maintenance Leaders programme and 195 people participated in the Shift Supervisors programme, accounting for a 47% FTE participation.

In the case of the Maintenance Leaders programme

For the case of the Shift Supervisors programme:

The impact on the business is seen in better role execution, from a higher knowledge of leadership topics to an impact on employee engagement, talent attraction and retention, and internal mobility.

Type of Performance Appraisal

The company conducts performance evaluations by objectives to all workers twice a year. At the beginning of each year, all employees establish their individual goals per management's expectations and/or plan for the year and the Group's overall objectives. 60% of the score obtained is linked to individual goals, and the remaining 40% is related to ensuring compliance with our code of conduct and deploying the behaviours of our charter of values. Progress is reviewed at half-year between the individual workers and their superiors, and the final performance evaluation is carried out at the end of the year.

In 2023, 95% of employees in the mining division and corporate office completed their performance appraisals. The remaining 5% of employees who did not complete their performance appraisals were due to a minimum of 6 months of seniority required for the evaluation to be carried out.

The following table shows the percentage of employees who completed the performance appraisal carried out in 2023, separated by mining group/corporate office and management level.

Health and Safety

Safe production based on a sustainable internal culture is our main asset. We have been making steady progress in spreading this approach at our Company's grassroots and among our contractors, supported by trust, planning and the principles of roles and responsibilities. As one of our five strategic pillars, health and safety is at the centre of our daily activities.

Our Approach to Climate Change

Climate change is one of our top priorities. We recognise the contribution of copper to increasing electrical demand relating to the worldwide energy transition and the need to adapt our operations to reduce our GHG emissions.

Our Progress towards Decarbonisation

At Antofagasta we have the ambition to reduce our Greenhouse Gas (GHG) emissions in the short and medium term, and to achieving carbon neutrality by 2050, or sooner if technology allows. Our comprehensive approach to decarbonisation involves our mining site operational teams, our corporate teams and our suppliers.

Energy Management

Energy is a strategic resource that must be managed in order to ensure a safe, efficient and sustainable supply for our operations, in accordance with our Climate Change Strategy. Energy represents approximately 18.9% of the total of operational costs of our mining operations. Of this percentage, about 10.4% corresponds to electricity and 8.5% to fuels, mainly diesel.

In accordance with our Energy Policy framework, implemented in 2022, we have incorporated the role of Energy Management Representative at each mining site. They supervise the achievement of decarbonisation and energy goals through energy performance plans and GHG reduction. The role consists of leading and ensuring the implementation and improvement of the Energy Management System according to Chilean Law No. 21,305 on Energy Efficiency.

Energy audits to identify opportunities for improving energy performance

During 2023, we conducted an audit to certify our Energy Management System ISO 50001:2018 at each of our mining operations, which was approved and certified by Bureau Veritas Chile. This system allows us to monitor our energy consumption in the areas of highest use within the company, where we need to demonstrate improvements in reducing our energy intensity.

This certification audit validated that each of our companies tracks Its energy consumption and manages it when it falls outside the established normal ranges, in addition to proposing improvements in this regard.

Quantified targets to address energy savings

Our Energy Management Systems at each site have objectives and goals associated with areas of Significant Energy Use, which include a KPI called the Energy Performance Indicator (EPI). These KPIs measure an energy variable against a relevant productive factor for the process. During 2023, each of our operations set the following objectives and achieved impacts as detailed below:

Actions to reduce the amount of energy use

Based on our Energy Management System, we have studied various initiatives currently in the evaluation stage and address significant energy use areas. These include the electrification of mining fleets and operational measures for plant areas. In this regard, we published our first climate action plan this year, which outlines the measures we are evaluating to decarbonise our mining operations through fleet electrification and energy management via our Energy Management System.

Evaluation of progress in reducing energy consumption

We track the significant energy uses (SEUs) of each company's Energy Management System (SGEn) to assess progress in reducing energy consumption. This tracking involves monthly comparisons of actual consumption against expected consumption using the Energy Baseline (LBEn), identifying causes of significant increases, and estimating reductions due to operational improvements.

Each company holds forums with senior management to present energy consumption data, evaluate control measures for out-of-range values, and provide updates on the status of their SGEn and commitments.

Use of clean or green energy

Since April 2022, all our mining operations have used only energy from renewable contracts. Furthermore, our corporate offices have a 98.4% renewable electricity supply. The remaining 16 tCO2e of Scope 2 emissions are due to non-renewable electricity consumption at our corporate offices. Our renewable contracts resulted in annual savings of 793,431 tCO2e comparing location-based versus market-based Scope 2 emissions.

Investments in innovation or R&D to decrease energy consumption

All investments in decarbonisation are aimed to reduce emissions and improve energy consumption efficiency. With a lens focused on long-term viability, we assessed emerging technologies’ availability that allows us to solve the challenge of charging the equipment with a substitute for diesel or a battery without generating stoppages or impacting the availability of that equipment. Among those solutions, we particularly focused on dynamic charging, allowing us to charge the truck while moving electrically. Another key factor to consider when choosing technologies is their potential to deliver economic benefits today and their potential to enable other technologies, such as fully electric vehicles, in the future. This process allows us to select technological solutions that meet immediate needs and are scalable for future enhancements. We have defined clear design principles for the transition, such as introducing dynamic charging onwards and potential upgrades to batteries in vehicles requiring engine rebuild from that date forward.

Energy efficiency training provided to employees to raise awareness of energy consumption reduction

Our company, certified under ISO 50001, has training plans focused on energy efficiency and provides corporate e-learning for all its mining sector employees.

See ISO 50001 certificates in the Sustainability Databook 2023

Water Stewardship

In 2023, in acknowledgement of the strategic value of water for our company and our own sustainability, we created the Water Resources Management area to improve technical advice and our role in planning. We also assigned a water lead expert at each mining site to improve water management and to increase water efficiency.

Leading Seawater Use

Antofagasta Minerals has long been a pioneer of the use of seawater in the Chilean mining industry. We are moving away from dependence on continental water sources and increasing seawater use. In 2023, we achieved two milestones: completion of the Los Pelambres desalination plant as the first of its type in central Chile, and operations at Centinela only use 100%1 seawater following Antucoya's lead.

Water Consumption in Water-Stressed Areas

The reported values do not account for the precipitation at Minera Los Pelambres.

Water Efficiency Management Programmes

Water use assessment to identify opportunities for water efficiency improvements and actions to reduce water consumption

Each company within the Antofagasta Minerals Group presents its performance metrics related to water usage according to the standards established by the International Council on Mining and Metals (ICMM) regarding efficiency, reuse, and recycling. This information is made publicly available annually through the company’s official platforms and is subject to external audits to ensure accuracy and transparency. The complete details of these reports are available on the Sustainability Databook 2023.

In accordance with our Water Policy and Climate Change Strategy, each company must have a Water Efficiency and New Technologies Implementation Plan. The goal is to promote the efficient use of water resources from continental sources, seawater, or other alternative sources by analysing water usage indicators and promoting the implementation of industry best practices. This complements Antofagasta Minerals' already implemented innovative initiatives, such as the use of seawater and thickened tailings technologies.

Actions to improve wastewater quality

The companies that are part of Antofagasta Minerals identify their discharges and manage them through specific monitoring and treatment actions as necessary. In the particular case of Minera Los Pelambres, the discharges from the desalination plant are monitored in accordance with the project's environmental monitoring plan, ensuring compliance with national discharge regulations for marine and inland water bodies (DS 90). Additionally, all companies in the group have wastewater treatment plants (WWTPs) for sanitary services. The effluents from these plants are treated and monitored to ensure they meet the established parameters in compliance with current regulations.

Establishment of targets to reduce water use

Antofagasta Minerals has a target for 90% of the water used by our operations to come from seawater and/or reused water once our desalination plant at Los Pelambres reaches its full capacity of 800 l/s.

Application of water recycling

In 2023, 84.7% of the water used in Antofagasta Minerals' Mining Group operations came from recycled and reused sources. This high percentage of reuse was achieved through various efficient and sustainable practices. Key reuse activities include the recirculation of water in tailings thickeners and tailings deposits and the recirculation of solutions used in heap leaching.

Awareness training provided to employees on water efficiency management programmes

Throughout 2023, presentations on the Water Management Standard were conducted for the Water Leads of the Mining Group's companies, where water efficiency is a key component of the standard. In addition to general presentations, specific training sessions were organised to address reporting and the implementation of stochastic water balances, which enable detailed identification of current water consumption and facilitate effective resource management and the adoption of measures that promote water efficiency.

Water Risk Management Programmes

Dependency-related water risks considered in risk assessment

Antofagasta Minerals has achieved several significant milestones in response to the water risks associated with dependency. The commencement of operations with 100% seawater at Minera Centinela in 2023, along with Antucoya, led to the cessation of extractions from wellfields. Additionally, in 2023, we completed the construction of Phase 1 of the Los Pelambres Future project, called "Complementary Infrastructure", which includes a desalination plant with a production capacity of 400 l/s of industrial-quality desalinated water. Furthermore, in October 2023, Los Pelambres received approval from the Coquimbo Environmental Evaluation Commission to expand the desalination plant, which aims to double the current production capacity to 800 l/s.

Impact-related water risks considered in risk assessment

The companies of Antofagasta Minerals are located in water-stressed areas. As such, they face the ongoing challenge of providing a secure supply while ensuring minimal impact on their surroundings. At the corporate level, the Water Resources Management is responsible for the Group's water management, with priorities including:

• Analysing the evolution of the water matrix, focusing on reducing the extraction of continental waters.
• Safety and reliability of the water supply.
• Promoting efficient water use and reducing the water footprint in operations.
• Achieving sustainable water performance and meeting climate change objectives.
• Establishing robust and transparent water management to report on our water management performance.

Regarding impacts, a cross-cutting risk is identified for the companies related to potential reductions and/or loss of water supply, which could partially affect or completely shut down operations.

Assessment of future water quantities available

Water and energy are enablers in each of Antofagasta Minerals' long-term mining plans: baseline case, development case, and Strategic Growth Plan. They are strategic inputs; there is no long-term plan without them. Antofagasta Minerals assesses future water availability and demand in this cycle based on the timelines of granted rights, existing infrastructure, and planned projects. From this information, various action plans are developed in line with possible demand scenarios, which are then subjected to technical and feasibility analysis to determine the optimal course of action.

Assessment of future water quality-related risks

Each of Antofagasta Minerals' projects is subject to an Environmental Impact Assessment (EIA) or Environmental Impact Declaration (DIA) to obtain an Environmental Qualification Resolution from the environmental authorities, which must detail, among other things, the risk associated with the alteration of baseline water quality in accordance with the provisions of the letter f) of Article 18 of D.S. N°40/2012 RSEIA.

Based on the studied baseline, an assessment is carried out to identify future risks related to water quality for the sector where the project is located. Environmental monitoring plans, early warning plans (PAT), and/or voluntary environmental commitments, which include hydrogeological and/or surface water monitoring, are implemented.

Assessment of impacts on local stakeholders

Impacts related to water resources and local stakeholders of the studied baseline of the sector where the project is located are analysed in the Environmental Impact Assessment (EIA) or Environmental Impact Declaration (DIA) that each of Antofagasta Minerals' projects are subject to. Impacts may include alterations to natural waterways due to the construction of new infrastructure (such as contour channels), surface water or changes in groundwater courses resulting from excavation activities in specific areas of the project, alterations in water quality, as well as changes in coastal oceanography, including current dynamics, winds, waves, among others.

A public participation phase is included in the process, allowing individuals and legal entities to become informed and provide input on a project or activity that may generate an environmental impact in their community. Within the framework of the project's Environmental Impact Study (EIA), Public Participation (PAC) allows individuals to:

• Access and review the physical or electronic evaluation file.
• Make observations.
• Receive responses to their observations.

This approach ensures that Antofagasta Minerals' projects meet regulatory requirements and guarantee community involvement.

Furthermore, Minera Los Pelambres actively participates in a Provincial Water Working Group established by the Regional Government to identify and implement solutions that improve water security in the area in the short, medium, and long term. This initiative has addressed drought challenges for both human and agricultural use by supporting rural drinking water wells, canal lining, and providing water for animal consumption.

Biodiversity Protection

Biodiversity protection is part of our long-term sustainability approach and policy. In 2023, our new, updated Biodiversity Standard started its implementation. In accordance with our Biodiversity Standard, and aligned with the ICMM's position statement on Mining and Protected Areas, we seek to protect wildlife around our mining sites.

Biodiversity Risk Assessment

Risk related to biodiversity in our four mining companies is assessed following Antofagasta´s risk management framework.

Our risk management methodology is applied to all of our operating companies, projects, exploration activities and support areas so that we have a comprehensive view of the uncertainties that could affect the achievement of our strategic goals. The framework is based on ISO 31000 and COSO ERM.1. The accurate and timely identification, assessment and management of principal risks give us a clear understanding of the actions required to achieve our objectives.

Risks associated with sustainability (among them biodiversity) – one of our five strategic pillars, jointly with health and safety – are monitored regularly to identify degrees of uncertainty and allow us to adopt measures in a timely fashion. Growing levels of risk, particularly in relation to climate change, impose new challenges that require an integrated approach.

Each operation holds an annual risk workshop, at which the business unit’s risks and mitigation activities are reviewed in detail and updated as necessary. Workshops assess principal risks that may affect relationships with stakeholders, limit resources, interrupt operations, and/or negatively affect potential future growth.

For more information, please check Antofagasta's Annual Report 2023, pages 74 to 85.

Waste Management

Action plans to reduce waste generation and integration of recycling programmes to reduce the waste sent to landfill

As part of Antofagasta's Circular Economy Strategy, action plans to reduce waste generation and integration of recycling programmes to reduce the waste sent to landfills have been implemented, such as:

Antucoya adapted and implemented the autonomous T-Rex 900 shredder to recycle High-Density Polyethylene (HDPE) industrial pipes and drippers. The shredder, adapted for this process, reduces the size of the plastic, allowing for more efficient transportation of HDPE to the recycling plant located in Santiago.

Antucoya transforms discarded HDPE pipes into mobile solar-powered lights to increase visibility in its leaching piles. The project, undertaken by the local company ID Chile, enhances worker safety.

FCAB — part of the Antofagasta plc group — sold 1,794 tons of locomotive parts, engines, bogies, and rails as scrap in 2022. It also donates wooden sleepers that have reached the end of their useful life for reuse in parks, urban squares, and community facilities in the Antofagasta, Calama, and Ollagüe communes and has installed 25 clean points for the collection and subsequent recycling of plastic bottles, aluminium cans, and office paper.

Quantified targets to minimise waste

The valorisation of industrial waste increased by 20% compared to 2022, with greater quantities of lubricating oils, drip lines, batteries, lead deposits, belts, scrap, and end-of-life tyres (ELTs) recycled.

Additionally, waste management is carried out within the framework of environmental and sectoral permits that authorise the operation.

Investment in innovation or R&D to minimise waste

As part of the Innovation Roadmap (IR), in 2023, we worked on the TECHNOLOGICAL PROGRAMME DEVELOPMENT “TAILINGS AND WATER MANAGEMENT,” with an amount of 365 thousand dollars.

The objective was to develop an innovation programme for tailings and water, with the main goal of creating a programme focused on these areas. The results achieved included defining the strategic intent, identifying four key areas for innovation, and pinpointing potential solution lines. Additionally, the programme involved technological monitoring, identifying innovative tailings treatment alternatives, prioritising technologies to study, and benchmarking, among other activities.

Implementing Our Circular Economy Strategy

In 2023, we launched our Circular Economy Strategy, approved at the end of 2022. Its three pillars are linked with four priorities: regulations and trends; engaging with stakeholders; innovation; and circular economy culture.

Innovation as a Driver of Sustainability
