Each Unit consisted of one common share of the Company ("Common Share") and one common share purchase warrant ("Warrant").

The net proceeds of the Private Placement will be used to advance exploration on the Company's Resguardo project in Chile, the Captain Project in British Columbia and for general working capital purposes.

The Company has relied on exemptions from the formal valuation and minority shareholder approval requirements of MI 61-101 contained in sections 5.5(a) and 5.7(1)(a) of MI 61-101 in respect of related party participation in the placement as neither the fair market value (as determined under MI 61-101) of the subject matter of, nor the fair market value of the consideration for, the transaction, insofar as it involved the related parties, exceeded 25% of the Company's market capitalization (as determined under MI 61-101).
