Outstanding metallurgical results demonstrate gold recoveries ofover96% through the leach
circuit at the RPM NorthDeposit;
oThe average head grade of the RPMmetallurgicalcomposite was1.34g/t Au. The overall
average tail grade achieved from thecomposite was less than0.15g/t Au.
Can someone explain the way the 96% recovery is calculated. I make if you start with 1.34g and leave .15g I make that 88.9%.
What am I missing?
