From the report:

AMEC expects that the 2011 drill program will provide local changes in the geological
model. In the area of the chargeability anomaly, drilling is indicating the presence of
previously unrecognised mineralization. Although insufficient data are currently
available to fully assess the impact of the drilling, AMEC expects that the results will
provide Project upside within the current pit shell, and therefore represent upside
potential for the next Mineral Resource estimate update.

Yaay, some upside potential.
