hole lotta gold

While going through our photos taken at a mine public lookout recently at Ravenswood, I spotted this one where the company states " Nolans Pit gets 2 million tonnes of gold per annum"
Thats either a massive boost to royalties or a missprint, and should be ammended to gold bearing ore. The public display has, by its faded condition been there a fair while and if the statement is ammiss I would have thought the company wuold have corrected it to protect their reporting integrity
