Richmont's main objective for the 2011 drilling campaign on Wasamac is to expand the overall resources on the Property and to evaluate the potential for an underground bulk mining operation. Additional drill results will be used to complete an updated resource calculation in Q4 2011 and a preliminary economic assessment in Q1 2012.

Richmont is also drilling on the adjacent Globex land package, optioned by Richmont from Globex Mining Enterprises Inc. in May 2011.
