("Cormark"), pursuant to which Cormark has agreed to purchase 2,650,000 units ("Units") at a price of C$0.38 per Unit and 4,226,000 flow-through common shares ("Flow-Through Shares") at a price of C$0.50 per Flow-Through Share of the Company, on a bought deal private placement basis, for aggregate gross proceeds to the Company of approximately C$3.1 million (the "Offering").
