ABOUT THE TWG
The SAIMM has established a Tailings Storage Facilities Working Group in response to recent global tailings facility failures and increasing focus on Tailings Storage Facilities Management within the increasing focus on Environmental, Social and Governance (ESG) matters by investors, NGOs, Governments and other interested stakeholders.
Following failures at the Mount Polley dam in Canada in August 2014, the Mariana dam failure at the Samarco mine in November 2015 and the collapse of the tailings dam at the Córrego do Feijão iron ore mine in the town of Brumadinho in January 2019, mining companies worldwide conducted reviews and audits of their facilities, and posted these on their websites.
The International Council on Mining and Metals (ICMM), of which most major mining companies are members, initiated a global project to develop a Global Industry Standard on Tailings Management which was published in August 2020, and which is linked to this website.
At approximately the same time, the International Commission on Large Dams (ICOLD) initiated a project to develop a set of guidelines for tailings storage facilities. This is soon to be released.
Against this background, the Global Mining Professionals Alliance, of which SAIMM is a member, initiated a Global Action on Tailings group, in which the SAIMM participates.
The GMPA GAT group is an international Taskforce of experts representing each GMPA association working together to build awareness and knowledge of tailings management through information on design, operation, risk management and improvement opportunities, and education and professional development activities to enhance competencies in tailings management.
In addition, each GMPA organization has established specialist tailings committees providing guidance on conferences, online technical education, publications, as well as strategic input into industry reviews and consultations.
The SAIMM Tailings Group is such a group, which has terms of reference as attached to the webpage.
The current focus of the group is on the following.
- Establishing a competency and qualifications working group to define professional roles, and the requirements in terms of qualifications, capabilities and registration
- Defining professional ethics and behaviour in TSF management
- Engaging with ICMM and ICOLD and translating standards and guidelines into local requirements and investigating whether a Southern African Code within SAMCODES is necessary, or if the update of SANS 10286 is sufficient
- Engaging with DMRE
- Liaising with research organisations to ensure collaboration and support
- Researching best practice from audits
- Engage with SAICE on update of SANS 10286
- Participating in the development and publication of SME book, representing the interests of Southern Africa
- Organising a regional tailings event.
The SAIMM working group is working closely with the South African Institute of Civil Engineers, specifically the SAICE Geotechnical division.

1. Background
Since the failures of tailings facilities in South America in particular, an unprecedented amount of activity has occurred globally, with many different groups being formed to fulfill mandates defined by their principles.
These groupings include:
- The Church of England and Swedish Pension Fund Groups who requested a global review on tailings facility safety and environmental impact, through a self audit process conducted buy mining companies;
- A response by the ICMM to produce appropriate standards and guidelines for TSF design and management, centered on risk assessment and design and management competency and control;
- The establishment of a project within the Global Mining Professionals Alliance (GMPA) that focusses on risk management systems, competency and monitoring and communications to potentially affected communities. The GMPA (of which SAIMM is a member) has requested that member organisations establish a local task team, and to have a representative reporting in on local activities, to the quarterly GMPA meetings. It has also requested the nomination of technical experts to serve on adhoc GMPA committees or task groups;
- The establishment of a Global Research Consortium on Tailings, made up largely of academic members and organisations, to investigate competency requirements and requisite qualifications;
- The establishment of a group and framework to develop guidelines by ICOLD for use by industry and regulators.
Locally, the Minerals Council South Africa has coordinated inputs into the ICMM group, and the SAICE has which is considerably out of date.
This all creates a picture of much activity, and the risk exists of duplication of effort, the development of conflicting outcomes, and the possibility of creating odious and unworkable global standards.
2. Duties of the SAIMM Task Group
- Report on activities relating to TSFs in Southern Africa to the GMPA;
- Keep a watching brief and coordinate activities in Southern Africa, where possible;
- Provide inputs and comments on global and local activities and documents;
- Liaise with academic institutions on the development of competency and qualifications;
- Arrange, through SAIMM, conferences and schools to disseminate new knowledge and standards, guidelines;
- Provide local technical input to global committees and task groups, to represent Southern African interests;
- Report back to other working groups in Southern Africa, on GMPA initiatives;
- On the assumption that a process similar to that related to Mineral Resource and Reserve reporting is required, provide input to a high level, principle based global framework, and develop structures for the development of local codes, standards and guidelines for the Southern African environment. This may involve establishing and guiding various sub-groups.
3. Constitution
The Task Group will be made up of industry experts, drawn from academia, industry, consultants and the regulator. There will be no fixed term of membership or limit on numbers, and new members may be seconded through the suggestion of members.
The group will meet on a quarterly basis, prior to the GMPA meetings.
Adhoc meetings may be called where necessary.
ABOUT THE Tailings Conference
Global Tailings Standards and Opportunities for the Mine of the Future
Tailings storage facilities have been a feature of mining operations around the globe since mining began. They are the depositories of waste or gangue material from mining operations and mineral processing plants, or the storage facilities for pollution control. In some cases, they may still contain low grade minerals, high grade fines that are not economically viable to treat. They may also contain reagents and other radioactive or potentially harmful minerals and chemicals, that could damage ecosystems in the event of their escape. Tailings facilities are each in a way unique, either in terms of location, terrain, design and construction. Furthermore, in terms of design and construction, debate occurs globally on the merits and demerits of upstream and downstream facilities, and wet or dry facilities.
