The Company completed 17 holes and multiple wedges during the campaign. The
drilling was primarily infill drilling with the holes selected to maximize the
potential conversion of inferred resources to measured and indicated resources
for inclusion in the Company’s Definitive Feasibility Study. The drilling
program was also designed to provide the core samples needed to complete the
remaining rock mechanic and metallurgical test work required for the
completion of a Definitive Feasibility Study.

The drilling was primarily performed by Boart Longyear, one of the premier
drilling companies in the world.

The completion of the drilling program is a critical step towards completion
of a Definitive Feasibility Study, and the Company is on track to complete an
updated NI 43-101 resource report by the end of 2013.
