Notes:
- CIM definitions were followed for the estimation of Mineral Resources.
- Mineral Resources for the Lac des Iles mine were estimated by Scott Wilson Roscoe Postle Associates, Inc.
- Mineral Resources for the Roby open pit were estimated at a cut-off grade of 1.8 g/t PdEq, within an optimized pit shell run below the current pit survey (October 2008).
- Mineral Resources in Lac des Iles mine stockpiles were estimated at a cut-off grade of 1.9 g/t PdEq.
- Mineral Resources for the Roby and Offset Zones underground were estimated at a cut-off grade of 5.8 g/t PdEq.
- Lac des Iles mine cut-off grades were determined under the assumption that a production rate of 14,000 tpd would be resumed in the event of restarting operations.
- For Lac des Iles mine, metal price assumptions of US$350/oz palladium, US$1,400/oz platinum, US$850/oz gold,US$6.50/lb nickel, and US$2.00/lb copper were used in the estimation of PdEq and cut-off grade. A US$/C$ exchange rate of C$1.11 was used.
- The mineral resource estimates for the Shebandowan West Project were prepared by F.H. Brown, CPG, Pr. Sci. Nat. (a “qualified person” under NI 43 101) using a cut-off grade of US$60.00 NSR and 18-month trailing average metal prices of US$300/oz palladium, US$750/oz platinum, US$400/oz gold, US$7/lb nickel and US$1.50/lb copper.
- Assumes a net inventory to North American Palladium of 50% for the Shebandowan West Project. The Company’s interest is currently 50%, which could be reduced to 40% upon the exercise by Vale Inco of a claw-back right.
- Palladium and platinum ounces are stated as contained ounces. Disclosure of contained ounces is permitted under Canadian regulations; however, the SEC generally permits resources to be reported only as in place tonnage and grade.
