(the “Underwriters”) under which the Underwriters have agreed to purchase, on a bought deal basis, 22,000 floating-rate convertible unsecured subordinated debentures (the “Debentures”) at a price per Debenture of $1,000 for total gross proceeds of $22,000,000 (the “Offering”). The Underwriters have been granted the option (the “Option”) to sell up to an additional 15% of the Offering, exercisable in whole or in part at any time up to 30 days following the closing of the Offering which is scheduled for on or about July 24, 2012 (the “Closing Date”).

The Debentures will mature on June 30, 2017 (the “Maturity Date”) and will bear interest, accruing, calculated and payable semi-annually in arrears on June 30 and December 31 of each year, at a fluctuating rate, of not less than 8.5% and not more than 13.5%, dependent on the simple average of the Ux Weekly Indicator (Spot Price) published by the Ux Consulting Company, LLC (the “UxC U308 Weekly Indicator Price”) during the applicable semi-annual period (or such shorter period of time, if applicable) according to the table below:

The first interest payment date is December 31, 2012, and will consist of interest accrued from and including the Closing Date calculated in accordance with the above table based on the simple average of the UxC U308 Weekly Indicator Price during the stub interest payment period.

The Debentures will be convertible at the holder’s option into common shares (“Common Shares”) of the Company at any time prior to the close of business on the earlier of the Maturity Date and the business day immediately preceding the date fixed for redemption of the Debentures at a conversion price of $0.30 per Common Share (the “Conversion Price”), being a ratio of 3,333.33 Common Shares per $1,000 principal amount of Debentures.

The Debentures will rank subordinate in right of payment of principal and interest to all present and future senior obligations of the Company and will rank pari-passu to all present and future unsecured indebtedness.

The Debentures will be offered by way of a short form prospectus in all provinces in Canada. The Company agrees that the Underwriters may distribute the Debentures in the United States by private placement to “qualified institutional buyers” as defined in Rule 144A, and such other jurisdictions as may be agreed upon by the Company and the Underwriters.

The Company intends to use the net proceeds of the Offering for mine development of the Company’s existing properties, permitting of the Sheep Mountain Project, and working capital.
