We recognise that we have a responsibility to the health of the environment and are committed to preventing, mitigating and controlling the impacts of our activities on the surrounding areas.
We look to produce our metals in a responsible manner and are focused on mitigating the negative impacts of our operations on the environment. We take our environmental responsibilities seriously and ensure that we comply with the laws and regulations of the countries of operation. Compliance with legal requirements is constantly monitored.
Central to CAML’s environmental work is the monitoring, measurement, analysis and evaluation of environmental aspects, such as water, air quality, soils, biodiversity, hazardous material handling, waste generation and recycling, greenhouse gas (‘GHG’) emissions and energy efficiency. Internal audits for environmental performance are undertaken frequently and documenting systems have been implemented at our operations. Comprehensive environmental management systems (‘EMS’) have been developed for both operations, with ISO14001 standards adhered to at Sasa (as confirmed by a 2019 audit). Leadership and commitment to these systems is demonstrated through our management approach and actions. IFC and Equator Principles are also implemented where feasible at both sites. Emergency response plans are in place for environmental situations at both operations.
Workforce education on environmental issues is considered important across the Group and is carried out via inductions, educational talks and other training sessions. We consider raising awareness of environmental issues important not only for employees but also amongst contractors and visitors. Constant competence and skills improvement for environmental employees is taken seriously.
Energy usage and emissions
CAML has committed to reporting its Scope 1 and Scope 2 emissions annually.

Air quality and pollution
Mining and processing operations produce air pollution both in the form of gases and dust. CAML is committed to preventing pollution of all environmental receptors, thereby aiming to remove any negative impact on the environment and human health, both for our employees and local communities.
The Company adheres to regulatory standards relating to air quality.
Air quality exceedences at Sasa and Kounrad in 2019
Water is a valuable and shared resource and one of the most important inputs in CAML’s production processes. At our operations, water is used for processing, dust management and domestic water services.
The Company is committed to the responsible and efficient use of water and to ensuring that discharges to the natural environment are at the appropriate environmental standards.
Decrease in net water consumption at Sasa
Waste generated from our mining and processing operations includes both mineral (mainly in the form of tailings) and non-mineral waste.
Significant spills at Sasa and Kounrad in 2019
Initiatives to reduce, reuse and recycle non-mineral waste in order to reduce the environmental impact of our operations are included within the site waste management plans and raising waste management awareness amongst employees, contractors and suppliers is a key focus in terms of our environmental practices. Training is regularly undertaken to facilitate appropriate on-site sorting.
The fundamental principles of waste management are as follows:
- our responsibility for ensuring the protection of environmental components (air, groundwater, soil) from pollution by waste production and consumption
- emphasis on the reuse, recycling, regeneration, cleaning or environmentally acceptable disposal of waste
- reduction of negative impact on the environment by using new technologies and equipment to reduce waste generation
- the prioritisation of preventive measures to eliminate the environmentally negative impacts of waste on the environment.
No tailings are produced at Kounrad due to the nature of the leaching operation, but mineral waste materials are generated by mining operations at Sasa, which must be effectively and responsibly managed.
CAML manages five tailings storage facilities (’TSF’) at Sasa, all of which are constructed using the downstream technique, widely viewed in the industry as the safest design. Construction of the newest dam, TSF4, was completed in 2019.
For more information on our tailings, please see separate page, ‘Tailings’.
Rehabilitation and biodiversity
The Company has mineral rights over 1,789 hectares of land, 73% of which is disturbed by its operations.
CAML is aware of the adverse effects that mining can have on biodiversity and has put in place specific programmes to manage and respond to biodiversity needs in the countries of operation.
Trees planted at Sasa since 2009
These programmes include:
- Mitigating the environmental impacts of our operations by implementing compensation measures, such as the rescue of species, soil conservation, restoration and reforestation
- Developing detailed closure plans for both operations to restore and recover the environmental conditions after metal production has ceased
- Restoring and, wherever possible, improving the conditions of the environment where our operations had been active by monitoring water bodies and flora and fauna, and by implementing ongoing improvement actions in line with local regulations. The teams have ongoing protection programmes for the flora and fauna to preserve native species in the ecosystems close to the operations.
Case study – Implementing successful water recycling strategies at Sasa
In order to assist in our goal to produce in a sustainable way, ensuring the efficient and effective use of water, Sasa carried out a Water Management Study in 2018, working together with Stip University.
Key recommendations from the study included:
- A reduction in surface water usage (abstraction from local catchments)
- An increase in contact water usage for processing
- Always maintaining a biological minimum level of water in rivers from which Sasa withdraws its resources
During 2019, we managed to significantly increase the percentage of contact and recycled waters used in the flotation plant from 0 to 47%. This equates to a reduction of freshwater abstraction for the flotation plant from 90 litres per second at the start of 2019 to 48 litres per second. Overall, Sasa demonstrated a 43% decrease in net water consumption in 2019 versus 2018. From 2020 onwards, the Sasa team will continue to maximise the use of recycled waters wherever possible.
