I'm really surprised by the met results. How come no one has questioned the 58% silver recovery? I know we are not a silver company, but that number is pretty low. The rest of the percentages are great however.
Could be worse:
Through 2007 and 2008 Barrick Gold offered a USD $10 million prize to the scientific community in a bid to improve silver recovery rates at its Veladero mine in Argentina.[31] Recovery rates for silver were below 7%, because the metal is bound within silica, which is difficult to dissolve using conventional cyanidation processing.[31] 1,750 researchers from 43 countries registered as participants with 130 proposals submitted.[32] Wikipedia
