Outlook

As of October 31, 2010, the existing reserves at the Nuestra Señora mine provide the equivalent of six years of production at the current processing capacity of the Nuestra Señora plant. In the Cosalá district, the Corporation has NI 43-101 compliant mineral resources at the San Rafael and El Cajón projects, as well as having several advanced exploration projects. The Corporation is aggressively advancing its exploration activities to further increase mineral resources and prove additional reserves.

The Nuestra Señora processing plant has an existing capacity of approximately 1,500 tonnes per day ("TPD"), but is expandable up to approximately 4,000 TPD. The Corporation has commenced engineering studies to quantify the investment required for varying expansion scenarios. Other growth alternatives being evaluated include the development of a second processing facility in the Cosalá district. Such expansion would allow for the diversification of process circuits and reduce the distances between multiple ore sources and processing facilities.

The Corporation will advance feasibility studies for the expansion of processing capacity and make development decisions during 2011.

The Corporation continues to seek new projects that would increase its asset base as well as enhance value for its shareholders.
