WATER RELATED CHALLENGES FOR THE MINING INDUSTRY Increasingly restrictive legislation & intensified corporate enforcement on water Water footprint is gaining in priority Acid rock drainage clean up national legislations (Peru: 300-400 ppm sulfates, Chile: 1000 ppm sulfates), Australia: [So4] down to 1000 ppm and TDS below 2400 ppm) Higher standards seeked for wastewater
Supply constraints Water scarcity in new mining operation areas Variations in water availabilities due to drought periods followed by flooding periods
Rising tariffs for water supply
Growing reliance on low grade ores requiring more water for extraction
