We are committed to being a responsible mining partner. To achieve this, we approach mine closure from a holistic and integrated perspective, understanding that responsible mining practices continuously evolve, as we strive to deliver a lasting positive legacy while balancing environmental protection and social wellbeing with financial performance.
We uphold our licence to operate through:
We see environmental rehabilitation as an opportunity to uplift our communities, leaving a positive legacy of alternative sustainable land use.
Due to the complex nature of environmental liabilities and rehabilitation, Exxaro adheres to several legislative frameworks that guide our management and approach. All assessments were done according to relevant regulations.
We review mine closure and rehabilitation financial provisions every year. Rehabilitation plans and closure objectives are amended after environmental management programme performance assessments. Cost estimates of activities in the concurrent and final closure rehabilitation programme are reviewed and adjusted. External auditors visit our sites, review documents and audit the provisions twice a year.
In 2021, we appointed consultants to compile reports on financial provisions for mine closure and rehabilitation. Except for ECC* and Leeuwpan, our operations were assessed in line with the regulations for financial provision for prospecting, exploration and mining operations (GNR 1147), which were published in December 2015 and amended in September 2018 by the DFFE.
New draft regulations (GN 765 in GG 45058) were issued on 27 August 2021 for comments. The proposed regulations will repeal GNR 1147. Exxaro forms part of the Environmental Policy Committee chaired by the Minerals Council and is aware of a draft of Financial Regulations published for comments on 27 August 2021. Discussions between the Minerals Council and the DMRE on the proposed regulations are still in progress. We continue engaging with all relevant parties on the financial rules attached to the entire mining industry.
External assessments were done at ECC*, Leeuwpan, Tshikondeni and Strathrea in 2021. If the new regulations are promulgated, all BUs will be assessed annually from 2022.
While we review the provisions annually, we use cutting edge systems and tools to manage environmental liabilities and rehabilitation. This year, we introduced a business analytics service to track expenses against budgeted figures. The application provides interactive visualisations and business intelligence capabilities, enabling timeous mitigation measures to be applied to fast-track concurrent rehabilitation.
At Cennergi, an external consultant is appointed to review the financial provisions for facility closure and rehabilitation every third year. We consider amendments to rehabilitation plans and closure objectives based on periodic environmental management programme performance assessments. The cost estimates of activities in the concurrent and final closure rehabilitation programme are reviewed and adjusted where necessary.
The implementation of our policy and practices at an operational level is overseen by the sustainability manager supported by the rehabilitation team and on-site environmental specialists under the leadership of the executive head: sustainability.
Each BU has five-year conceptual concurrent rehabilitation plans, schedules and associated budgets to:

Disturbed area is the footprint of disturbed area and includes all buildings, roads and mining areas that need to be rehabilitated, according to the Environmental Management Programme. Rehabilitated area is the area rehabilitated up to the required standard of the Environmental Management Programme and the final land use plan at which point only maintenance and monitoring is needed.
Land disturbed versus land rehabilitated (ha)
We are committed to rehabilitation beyond compliance. We believe it is our moral responsibility to conduct concurrent rehabilitation in a changing regulatory, economic and operating landscape.
On 31 December 2021, total land disturbed was 9 280ha (2020: 9 889ha) and total rehabilitated 1 933ha (2020: 1 981ha). Exxaro's Environmental Rehabilitation Fund (EERF) and additional bank guarantees provide for new developments and cover shortfalls in financial provisions.
The EERF's assets are managed in terms of asset and liability modelling aligned with risk, return and liability on each site. The objective is to maximise investment growth in the cost of liability provisions. An external specialist supports EERF trustees with technical skills required to profile and identify suitable structures for assessment by the trustees.
Current implementation includes:
Quarterly contributions to the EERF are based on closure cost estimates at LoM without considering any guarantees in place.
The Exxaro and the Matla rehabilitation trust funds (the funds) combined have shown growth of R261 million (2020: R249 million), mainly relating to cash contributions, interest earned on investments and fair value adjustments. The funds have grown by 13.0% (2020: 12.1%) from an opening balance of R2 006 million in January 2021 to R2 266 million in December 2021. In addition, Exxaro had bank guarantees of R3 606 million in place at year end. Updating these provisions twice a year highlights potential rehabilitation alternatives that could decrease the long-term closure liabilities of operations.
Calculation of rehabilitation cost is governed by relevant legislation (GNR 1147). It is conducted by independent technical and financial specialists, and our internal sustainability and finance departments, with expertise and experience in environmental management.
In 2021, our total unscheduled closure costs were R7 581 million (2020: R8 608 million).

Four Exxaro operations were in active closure in 2021, namely Tshikondeni, Durnacol, Hlobane and Strathrae (2020: five).
We understand that operational closure, concurrent rehabilitation, and land management activities directly connect employees, communities, the environment, government and infrastructure.
We are committed to:
Our land management goals for 2021 included transferring 90% of post-mining land to emerging farmers in local communities by 2026. We continued to create strategic partnerships with farmers to advance agri-economies in support of government's land redistribution policies.
Operational closure, concurrent rehabilitation and land management are part of Exxaro's operating philosophy and moral responsibility. We actively plan our operations with closure in mind, ensuring adequate financial resources are available to meet our rehabilitation commitments.
We also strive to integrate land and rehabilitation liability management in daily mine planning. This minimises final closure costs for each operation and optimises final land use after closure. All operations report concurrent rehabilitation KPIs every two weeks on Exxaro's Middle Eye platform.
The diagram below shows the 11 aspects that must be taken into account when closing a mine.
The social aspects of mine closure are integrated into our approach. These include the following principles:
Cennergi reviews its financial provisions for facility closure and rehabilitation every three years, and considers amendments to rehabilitation plans and closure objectives, based on periodic environmental management programme performance assessments. The cost estimates of activities in the concurrent and final closure rehabilitation programme are reviewed and adjusted where necessary.
We aim to:
