Impacted Mine Water Initiatives Jacques Cilliers Watercare Mining On behalves of Melanie Vermaak
Strategic View On Water Ability to Mine is Linked to Stewardship Credentials Water Stewardship is Key Credential Water is Strategic to Sustainable Business Business Continuity Business Sustainability Business Growth Water is an Asset and not a Liability Water is a Resource to be Actively Managed and Conserved Innovate For Sustainability and Success Harmony and Watercare Mining Formed Technical Partnership in 2015
Risks And Concerns Security of Sustainable Supply Drought is Highlighting Business Risk Possible Reduction or Loss of Production Harmony Don’t Generate AMD, Do Impact on Water Quality Harmony Generate Excess Mine Impacted Water by Virtue of Mining Activities Mine Water Management is an ACTIVE Process
Initiatives Aggressively Reduce Consumption Footprint Optimize Recycling Efforts Independence from 3rd party Service Providers Benefit Host Communities Benefit Nasional Reserve Current Projects 100% Reduction of Fresh / Potable Water at Doornkop 30% Reduction of Fresh / Potable Water in Carletonville 30% Reduction of Fresh / Potable Water in Welkom
