Private Placement

The Company further announces that it proposes to undertake a non-brokered private placement (the "Offering") to raise gross proceeds of up to $750,000 through the sale of up to 10,000,000 units (each, a "Unit") of the Company at a price of $0.075 per Unit. Each Unit consists of one post-consolidation common share and one-half of a share purchase warrant, with each whole warrant exercisable into one further post-consolidation common share at a price of $0.10 for a term of 12 months.

The proceeds from the Offering will be used to pay trade payables, existing liabilities, exploration work and for general working capital.

Finders' fees may be paid in connection with the Offering in accordance with the policies of the TSXV. The Offering is subject to the approval of the TSXV.
