Managing and conserving water

Potential impacts to ground and surface water resources are among the most significant environmental risks faced by the Company’s operations, making it a key point for engagement with communities and other water users who share water resources in the catchment.

Our water management standard mandates the comprehensive understanding of water risks and the implementation of tailored management and monitoring plans, supported by context-specific objectives and targets.

Our operations source water from rivers, lakes or groundwater aquifers, subject to conditions set by regulatory authorisations, often after a licencing process that take into account the needs of communities and other water users in the catchment. In addition, water is often purchased from water utilities and precipitation that falls onto mining infrastructure areas, or groundwater that drains into mine workings, is absorbed into the process water inventory.

A core objective for operational water management is to minimise new water withdrawals from the ground and surface water bodies and to maximise our recycling and reuse of water to the extent possible. Another core objective is to prevent contamination of water resources through our activities. This is achieved by either maintaining zero water discharge on sites, or by treating and releasing excess water from the process circuit, which is typically the case for high rainfall areas.

During 2021, Iduapriem mine’s water treatment facility was expanded to accommodate greater water volumes to be released from the process water inventory during construction and the ramp-up of a planned new tailings facility. Rehabilitation of Iduapriem’s Block 1 waste rock facility, that required active treatment of low pH seepage water, was reworked to encapsulate acid generating rock more effectively, and to reduce rainfall infiltration.

The in-situ groundwater remediation project in Tanzania progressed more slowly than planned, with a joint venture partnership between Sensatec Tanzania and German-based technology provider established late last year. Phase 1 of the production scale project is planned to start in earnest during 2022.

A site-wide water optimisation project started at Tropicana and aims to reduce water abstraction from aquifers and use water by preference, namely water from higher eficiency bores requiring less energy consumption and providing higher water yields, including those around the mine’s TSF. Variable speed pumps with reduced energy usage, operating off the mine’s internal electricity supply grid, have been introduced, eliminating the need for stand-alone diesel generators, which further helps to reduce GHG emissions. The project resulted in an increase of the site’s recycled water and cut diesel consumption for the borefield pumping by up to 35%

Responsible water stewardship is vital for AngloGold Ashanti, with water being a valuable, often scarce resource crucial for a variety of operational tasks and hygiene services.

Water sources significantly affected by withdrawal of water

The 401,000 ha Niger-Tinkisso Ramsar site is an extensive area of river and freshwater ponds and marshes between and around the Tinkisso and Niger Rivers, however its boundaries are not clearly defined. As many as 101,000 ha of the Ramsar site may overlap the (159,000 ha) Siguiri mine concession in Guinea. The mine abstracts less than 0.5% of the Tinkisso River’s annual flow.

Value of environmental fines

A USD 84,000-equivalent fine was paid by the Quebradona project to the Regional Environmental Authority following a violation in La Fea tributary in 2011 (Note: this is below the significance threshold of USD 100k).

Cuiaba mine was levied a fine over equivalent to USD 141,500 following a 2020 environmental incident, however the appeal process continued during 2021.

Reportable Incident Summary

Event Type Site Date Event Summary
Process water spill Obuasi 17 March 2021 An HDPE pipe, that transports underground mine water to the process plant area, was found leaking behind the KMS Shaft’s compressor house. It had failed at a fusion joint. The spill was estimated as 270m3 and contained dissolved arsenic in excess of the Ghanaian discharge limit. It entered the nearby stormwater drainage system and made its way into a wetland.   After switching off the pumps, the joint was rewelded and the system was restarted. Precautionary measures to reduce pipeline pressure were later taken. Water samples taken along the discharge path showed that the spill was diluted shortly by the streamflow volume, shortly after entering the wetland.
Process water spill Cuiaba 01 April 2021 A PVC pipeline conveying excess spillage from the milling and flotation plant to the mine’s new tailings filtration and drying area failed, releasing sediment-laden water onto access roads within the immediate area. A portion of the spill entered a nearby stormwater channel and reached the Sabará River, impacting it visually over a length of about 40 metres. While water analyses in the impacted zone did not reflect a determinable impact on water chemistry, the spillage included constituents marginally above applicable release limits. Approximately 90 m3 of sediment was recovered from the impacted area. The PVC pipeline was replaced with a more durable HDPE pipeline and additional monitoring cameras were installed along the pipeline, as was the frequency of physical inspections.
Tailings slurry spill Córrego do Sitio 05 May 2021 A concrete channel transporting tailings slurry by gravity from the process plant to the mine’s Tailings Storage Facility, overflowed at an inspection point, where it was uncovered. An estimated 30m3 of tailings spilled over into an adjacent concrete channel that drains treated mine effluent water from the process plant to the Conceição river. The tailings flow was stopped and the event was communicated to the relevant authorities and representatives of downstream communities. Samples of the spill-impacted effluent water indicated that the legal release limit for dissolved arsenic, manganese and total suspended solids had been exceeded. Upstream and downstream water quality analysis continued during clean-up activities that we immediately initiated and completed by May 27th. Additional information was requested from AGA after inspections by the State Env Agency, National Mining Agency, Environmental Police and the State Public Attorney. On Aug 27th a notice of violation and associated fine of R$ 183k (US$35k) was received from the authorities. Measures to prevent a recurrence include installation of physical barriers between the two channels, and monitoring cameras at points of high-risk.
Process water spill Obuasi 10 June 2021 Staff at Obuasi’s South Processing Plant discovered an estimated 3m3 of process water seeping into the stone pitched drain that transects the process plant, and directs rainwater from higher-lying ground off the operational area to a downstream watercourse, via the central Channel 13. Plant operations were immediately shut down and water samples were taken at four different locations; from Channel 13, the Nyankumasu watercourse, up to the downstream Nyam river. Cyanide concentrations in the Nyamkumasu stretch were found to be above the permissible limit, but within the standard at the Nyam river sample location. The water sampling continued up to June 13, to confirm the situation had fully normalised.
Process water spill Córrego do Sitio 15 July 2021 Volumes of water being pumped to surface from the Córrego do Sitio I underground mine, for treatment and release, exceeded the storage tank’s capacity. This resulted in an estimated overflow of approximately 500m3 of untreated mine water reaching the downstream Conceição River. The untreated water contained high levels of suspended solids and dissolved arsenic levels marginally over the release limit. Once detected, the overflow was stopped and field sampling initiated. While the event did not trigger regulatory reporting thresholds it was classified as ‘High’ in accordance with AGA’s environmental incident management standard. Investigations revealed that flow rates from the mine had increased progressively, placing pressure on the flexibility of the water treatment system. Measures to prevent recurrence included review and amendment of the facility’s water treatment capacity, and improved control and information systems for operators.
