No option to store water within a dry stack facility. A conventional tailings facility, designed to store water, can provide a mining operation with a buffer ( storm water storage) to maintain operations during dry months of the year. Oxidation of sulphides in the tailings can create high concentrations (but low volume) of seepage water.

· Tailings are thickened into a paste by removing excess water and recycling the water back into the mine processing stream via holding ponds. First adopted in the 1980s, and following Earle Klohn's prescient address to the University of Missouri in 1977 on the advantages of producing "dry" tailings (McLeod et al. 2015), the process of thickening tailings was capitalintensive and expensive.
gold, referred to as flour, flood, or colloidal gold, is lost in processing. Early miners recovered no more than 60% of assayed gold values, and as late as 1945 recovery of free gold averaged only 7075% (Spiller, 1983). Moreover, it is likely that most remaining placer deposits have a higher percentage
