The numbers posted on the header come from the reserves determined in the FS, which were derived from the resource numbers you posted. The May 2012 RE was input to the FS to create a mine plan and provide a high quality estimate of how much of the metal contained in the RE can be extracted economically. In general, you rarely get a pit design that recovers all of the metal in the RE but the metal that can be extracted is classed as reserves which command a higher market value.
