Too often, dry stacking or filtered tailings management is dismissed early in the alternatives assessment process due to the high production rates of many projects.
Running an effective and efficient exploration programme, be it in a well established jurisdiction or a remote location, not only requires a firm grasp of the geological and metallogenic processes and a competent geological team, but also robust field management and logistics.
Following catastrophic failures at Brumadinho (Brazil; 2019), Mariana (Brazil; 2015) and Mount Polley (Canada; 2014), there has been an ever-increasing focus on Tailings Storage Facility safety, both within the mining industry and by the wider public.
