This survey will be submitted to the relevant authorities along with a technical document that defines the physical methods for clean-up and disposal of the tailings. The clean-up of an initial high-priority section of the Kamenica River commenced last week with the agreement of the authorities.\n Wardell Armstrong Limited has been engaged together with local consultants, EcoMosaic to assess the social and environmental impact on the full length of the river (approximately 14 kilometres) and lake. EcoMosaic will lead the Environmental and Social Damage Assessment and Wardell Armstrong will produce a Remediation and Mitigation Report. These consultants will be on site this week to agree the work programme, which should commence in early October. \n Along the river, 17 sampling points have been established and samples have been taken daily since 14 September 2020 and sent to an independent accredited laboratory. Samples analysed in the days after the event have demonstrated that lead, iron, arsenic and cadmium are all within the allowed levels of Sasa's mining licence terms at all sampling points along the length of the river. While zinc and manganese levels are slightly elevated, this is also the case up-stream before the river enters the Sasa mining licence area and recent readings are in line with typical historic trends. In addition, there has been no material impact on dissolved oxygen levels at any of the monitoring stations. \n Sasa management team has been informed that the Ministry of Environment and Physical...
