Environmental, social and governance report for the year ended 31 December 2024 

Integrating mine closure and rehabilitation

We take a holistic, integrated approach to mine closure and rehabilitation*, balancing environmental stewardship, social wellbeing and financial sustainability. Our commitment to environmental rehabilitation also creates opportunities to support our employees and communities through sustainable land use alternatives.

Showcasing our response in action

Exxaro is advancing the rehabilitation of Durnacol discard dump 7, a legacy site from historical mining activities at Durnacol. As part of our commitment to responsible environmental stewardship, this project is restoring the site through comprehensive rehabilitation efforts that improve land stability, enhance water management and support long-term ecological recovery.

Dump 7 comprises a combination of burned and partially burned discard, along with coal slurry co-disposed over time. The rehabilitation strategy includes final profiling of the dump, the construction of contour benches and the covering of intra-bench slopes and plateau areas with stabilising materials. Additionally, stormwater management infrastructure, including down chutes and concrete energy dissipation structures, is being installed to control runoff and minimise erosion. By integrating advanced rehabilitation techniques and strategic land management, we aim to restore the integrity of the Durnacol site while contributing to sustainable land use practices in the region.

The project was initiated in October 2022, with a contractor appointed to execute the rehabilitation in 2023. To date, 75% of the work has been completed, including the covering of 19.2ha of the dump's top surface and the partial installation of stormwater chutes using repurposed concrete railway sleepers. The project continues to progress according to plan, with complete rehabilitation scheduled for September 2025.

Social impacts

* Mine rehabilitation restores the post-mined landscape to the intended post-mining land use.

Our mine closure and rehabilitation management approach at a glance

Our mine closure and rehabilitation plans integrate land management with ongoing operational planning, aiming to minimise closure costs and optimise sustainable post-mining land use. Execution of this approach is driven through:

Accountability and responsibility

Our sustainability managers, supported by the rehabilitation team and on-site environmental specialists, led by the chief sustainable impact officer, oversee the implementation of our policy and practices. BUs are accountable for concurrent rehabilitation and have site-specific rehabilitation procedures to follow.

Regulatory compliance

We manage our environmental liabilities and land rehabilitation in compliance with all relevant legislation, including section 24P of the NEMA. Financial provisions for rehabilitation costs and effective mine closure are calculated in terms of Government Notice R1147 (GNR1147) regulations. Our reporting aligns with MPRDA requirements.

Beyond compliance

Exxaro applies international rehabilitation standards, including Coaltech protocols, and innovative environmental solutions. Through collaborations with partners such as the Impact Catalyst, we work to create sustainable post-mining economies in host communities and aim to transfer 90% of rehabilitated land to emerging farmers by 2026.

Our comprehensive approach to land management, mine closure and concurrent rehabilitation is outlined on the following page. This approach focuses on supporting sustainable outcomes through:

  • Assessing impacts on employees, communities, the environment, government and infrastructure
  • Proactively managing environmental effects to limit residual liabilities, particularly in areas such as water quality, water retention and soil health, which could influence Exxaro’s financial resilience
  • Executing concurrent rehabilitation in alignment with operational timelines
  • Protecting rehabilitated areas from water ingress
  • Establishing financial provisions for all operational and closure sites, with annual assessments by our sustainability and finance teams in partnership with independent specialists
  • Updating and approving liabilities through structured internal governance processes
Closure and rehabilitation strategic objectives
Integrating concurrent rehabilitation and mine closure into daily operations at all BUs
Aligning with standards that promote sustainable post-mining land uses, including vegetation suitable for carbon sequestration
Setting specific, measurable targets for concurrent and continuous rehabilitation
Embedding accountability within operational management KPIs
Lowering the environmental financial liability associated with mine closure

Annual environmental liabilities are approved through internal governance processes and updated as follows:

Identify impacts and
rehabilitation areas
  • Add identified impacts
  • Remove rehabilitated areas
 
Adjust tariffs and
escalation
  • Current tariffs and producer price index escalation
 
Separation of immediate
and LoM cost
  • Apply definition and optimisation option
 
Calculate and prioritise
concurrent liability
  • Prioritise rehabilitation according to environmental risk assessment
  • Calculate volumes to be moved during concurrent rehabilitation
 
Schedule concurrent
rehabilitation
  • Schedule rehabilitation according to mine plan schedule
 
Budget
  • Budget the first year per month and the next four years per annum in five-year slices
 
Report
  • Report monthly physical movement against budget
 

Exxaro developed a new mine closure and rehabilitation strategy this year, underpinned by our updated policy and management standard changes. The strategy, policy and management standard changes progressing through board approval for early 2025, align with our Sustainable Growth and Impact strategy. The new strategy outlines specific roles, responsibilities and metrics for tracking rehabilitation progress across all BUs. A key focus of the updated strategy is on final land use outcomes, enhancing social impact after closure, and integrating environmental and social sustainability into land rehabilitation efforts.

Integrating social impact

Our approach is closely aligned with Exxaro's Social Impact strategy, integrating principles that support employee and community resilience both during and after mine closure.

Key areas of focus include equipping employees with portable skills for alternative employment, establishing effective communication plans and delivering specialised training for managing closure plans.

We prioritise safety, health and job creation in impacted communities, ensuring ongoing socio-economic activities and identifying stakeholder needs to guide our closure practices. Our commitment extends to preparing host communities with skills for commercial and infrastructure use post-closure, while maintaining alignment with SLP commitments to improve quality of life.

Through active engagement with communities, government bodies and NGOs, we strive to ensure a responsible and liability-free closure that meets community expectations and supports a sustainable transition.

Integrated stages of mining and mine closure planning

We aim to incorporate land and liability management into daily mine planning to reduce final closure costs and enhance post-closure land use for each operation.

1 Monitoring, measuring and reporting

  • Leverage advanced systems and tools to oversee environmental liabilities and rehabilitation efforts
  • Operations provide updates on concurrent rehabilitation KPIs through monthly management reports

Regular environmental management programme performance assessments guide amendments to rehabilitation plans and closure objectives.

2 Social impact

We remain committed to transferring 90% of rehabilitated post-mining land to emerging farmers in local communities by 2026.

To manage Exxaro-owned land effectively and efficiently while supporting current and future operations, biodiversity offsets and social impact initiatives, we categorise land parcels as follows:

Long-term agricultural leases

Through our minerals succession programme (MSP) we empower farmers by providing access to funding, mechanisation, inputs and training under a three-year contract with an external service provider.

Available land for emerging farmers and communities

  • Mpumalanga
    • Strathrae: 5 447ha (seven farmers on 4 495ha for crop and cattle farming)
    • Sheepmore: 740ha (two farmers on 740ha for cattle farming)
  • KwaZulu-Natal
    • Durnacol: 190ha (110ha leased to one female farmer for cultivation)
  • Limpopo
    • Lephalale: 296ha (112ha leased to three entities for intensive vegetable farming)

Land is diversified for agricultural use, including dryland maize, soya bean cultivation and livestock farming). Internal and external audits evaluate farm transfer success.

Donations

  • Donate land where either a right is established or social impact can be achieved (such as local municipality projects)
  • Transfer land under claims to government for redistribution
  • Support resettlement and local government projects in areas where our operations impact communities
  • Help uplift communities (such as Phumulani agri-village in Belfast) through livelihood restoration programmes

Current and future operations

Areas designated for operations are actively managed to protect against land grabs and ensure our sustainability.

Biodiversity and conservation

  • Preserve harmony between operations and natural surroundings, such as at Manketti game reserve
  • Maintain biodiversity management plans (including alien invasive control) and sensitive ecosystem enhancement to uphold environmental licences to operate
  • Control invasive alien plant growth to improve water quality, surface water runoff and indigenous vegetation health, increasing biodiversity and productive land availability

3 Employee engagement and development

  • Provide employees with portable skills, such as vegetable farming to support their transition into alternative employment and economic opportunities
  • Deliver training programmes that enable employees to implement and manage mine closure plans effectively
  • Implement a communication plan for employees

4 Infrastructure

  • Assess power lines, water pipes, buildings and dams and retain infrastructure that supports sustainable final land use
  • Integrate retained assets into the final closure environmental management plan and transfer them to an appropriate entity for ongoing management

5 Assets

Redundant but serviceable assets, such as vehicles and furniture, are retained if they can support social impact programmes and transferred to appropriate entities for implementation

6 Financial

We conduct annual reviews of our mine closure and rehabilitation obligations, with plans and closure objectives updated based on environmental management programme performance assessments. Cost estimates for concurrent and final closure rehabilitation activities are evaluated and adjusted. External auditors carry out biannual site visits, document reviews, and environmental liability audits, identifying potential rehabilitation alternatives to reduce long-term closure liabilities.

CENNERGI
An external consultant reviews Cennergi’s financial provisions for facility closure and rehabilitation every three years. Cennergi reviews and adjusts cost estimates for concurrent and final closure rehabilitation programmes as needed.

Exxaro’s Environmental Rehabilitation Fund, along with bank and insurance guarantees, supports new developments and addresses financial provision shortfalls. The fund’s assets are managed in terms of asset and liability modelling, ensuring alignment with site-specific risks, returns, and liabilities. The fund’s goal is to maximise investment growth relative to liability costs. Trustees are supported by an external specialist who provides technical expertise to assess and recommend suitable investment structures. Current implementation includes:

  • Two income building blocks benchmarked against cash rates and investing in government treasury bills, banks and corporate paper
  • Three growth building blocks targeting inflation-linked returns and investment in insurance and bank-guaranteed products
  • Equity-driven portfolios without explicit investment guarantees, where capital risk is controlled by managing volatility through portfolio adjustments

7 Community safety, health and job creation

Programmes such as the MSP are in place to address health and safety issues, as well as employment opportunities for communities.

8 Mining plan

Each BU maintains five-year conceptual concurrent rehabilitation plans, schedules and associated budgets to:

  • Establish measurable targets
  • Prevent backlogs that could increase rehabilitation liabilities
  • Enable managers to implement strategies without cash flow constraints
  • Integrate concurrent rehabilitation in operational tracking

9 Safety and risk control

Health and safety standards at mines undergoing closure are as rigorous as those at operational mines. Exxaro applies consistent health and safety policies across all its operations, including those in closure. Security risks remain a significant challenge during the closure process, requiring continuous safeguarding of infrastructure and assets to ensure safety and compliance.

10 Interested and affected parties

  • Ensure socio-economic activities can continue after mine closure
  • Identify the needs and expectations of stakeholders and socio-economic impacts
  • Assist host communities in acquiring skills for commercial activities and infrastructure use after mine closure
  • Create opportunities to enhance quality of life for affected communities
  • Align closure with community expectations to honour SLP commitments
  • Develop and implement plans for engagement with communities, government and NGOs, among others
  • Assist mine owners and operators achieve liability-free closure within a reasonable timeframe

11 Environmental stewardship

Exxaro’s disturbed footprint, which encompasses buildings, roads, and mining areas, is rehabilitated in accordance with the environmental management programme and aligned with the final land use plan, including provisions for ongoing maintenance and monitoring.

Rehabilitated land increased by 477.27ha due to Matla rehabilitated areas being signed off and handed to external farmers for utilisation. Although this led to an overall decrease in land disturbed compared to 2023, new areas opened for mining in 2024 increased land disturbed by 243.75ha.

Active sites

Concurrent rehabilitation continued at all active sites, with substantial investment allocated to backfilling mined-out areas. While exceeding the initial budget, this proactive approach allowed for more extensive rehabilitation. However, challenges such as equipment limitations, regulatory delays and extreme weather conditions impacted the timely completion of backfilling activities. To optimise future backfilling processes and reduce environmental impact, we aim to improve planning, resource allocation and stakeholder collaboration.

Government indefinitely postponed the expected NEMA financial provisioning for mine closure regulations in February 2024. This delay creates legislative uncertainty in financial provisions for environmental rehabilitation. In the interim, Exxaro follows GNR1147 for liability calculations.

We completed the rehabilitation of 477ha of land at Matla mine, which was transferred to local farmers for agricultural use. The land is used for cattle and crop farming and supports local economic activity.

The design phase for a new Grootegeluk dump is underway and expected to be finalised in 2025. We have actively engaged with government authorities to finalise the rehabilitation designs for Grootegeluk dumps 4 and 5. Productive discussions with the DWS confirmed the requirements for the new designs. Exxaro appointed specialists to lead the design process, ensuring that our rehabilitation plans meet regulatory standards and follow environmental best practices.

Inactive sites

Exxaro progressed on rehabilitation projects at Fripp, Zwartkops and Hoornbosch. At Fripp, headgear was dismantled, and the shaft sealed, with further physical rehabilitation scheduled for 2025 following plan approval. The Zwartkops site was secured, with a comprehensive rehabilitation plan under development for completion in 2025.

Closed mines

Rehabilitation at Tshikondeni mine progressed well, with 80% of planned work completed by year end and finalisation set for May 2025. The discard dump showed early signs of natural vegetation regrowth, prompting a detailed assessment of soil and vegetation to guide

further enhancements. At Durnacol, the design for dump 3 was approved, preparing the site for rehabilitation activities to begin in 2025. Exxaro appointed a service provider to implement a water treatment solution to treat the decant from the closed mine at Durnacol, with the plant operating since November 2024. This initiative aims to address the long-lasting issue of acid mine drainage and contributes to the protection of local ecosystems and water resources.

Work is also progressing at Hlobane, where the design phase is set to complete in the first half of 2025. A water treatment solution is under review by the DWS as part of our integrated WUL application, and we appointed a specialist to explore alternative options for optimal environmental performance.

Our primary focus in 2025 will be:

  • Aligning rehabilitation schedules with mine schedules and tracking performance monthly
  • Updating closure liabilities monthly to address financial sensitivities
  • Implementing the water treatment solution at Durnacol
  • Finalising rehabilitation designs for Grootegeluk and Hlobane dumps
