The tonnes of ore and contained ounces of gold presented in the Technical Report now filed on SEDAR are higher than those stated in the original press release. This change resulted from a correction made to the specific gravity used in calculations for the La Jojoba deposit.

The differences in the tonnes (605,334 tonnes) and contained gold ounces (15,049 oz. Au) for La Jojoba that result from this correction are shown in the following table.
