This contributed to a total reduced total of the latest tonnage advertised to possess the newest measured and inferred kinds when comparing to beliefs advertised within the the new 2004 financing guess.

The fresh new 2008 pre-feasibility data together with integrated the original NI 43-101 mineral set aside guess for the Casino investment. The brand new set aside estimate will be based upon gap build and the exploit manufacturing schedule designed in the new pre-feasibility analysis and is stated since a mill ore set aside and you can pile leach set aside.
