Canaccord Genuity Corp. and Red Cloud Securities Inc. acted as finders in connection with the offering. In consideration for acting as a finder in connection with the offering, the corporation paid an aggregate of $3,000 in cash finders' fees to the finders, representing 6 per cent of the gross proceeds of the traditional flow-through shares that were sold to subscribers introduced by such parties, and issued an aggregate of 24,000 non-transferable warrants to purchase common shares in the capital of the corporation to the finders, representing 6 per cent of the traditional flow-through shares that were sold to subscribers introduced by such parties, with each finder's warrant being exercisable for one finder's warrant share at a price of 10.5 cents per finder's warrant share until Sept. 26, 2026.

The net proceeds from the sale of the common shares will be used for exploration and development activities, feasibility study work, permitting activities, and working capital and general corporate purposes.

Ocean Partners U.K. Ltd., an insider of the corporation, and funds managed by Equinox Partners Investment Management LLC, an insider of the corporation, subscribed for 7,719,047 common shares and 7,719,048 common shares, respectively, under the offering on the same terms as arm's-length investors. Additionally, the corporation understands that Ocean Partners and funds managed by Equinox Partners were each party to an arrangement with the initial subscribers of the charitable flow-through shares or donees thereof, pursuant to which Ocean Partners and funds managed by Equinox Partners each purchased 5.75 million common shares in the capital of the corporation. The participation of Ocean Partners and Equinox Partners in the offering constitutes a related-party transaction for the purposes of Multilateral Instrument 61-101 (Protection of Minority Security Holders in Special Transactions). The corporation is exempt from the requirements to obtain a formal valuation or minority shareholder approval in connection with the offering in reliance on sections 5.5(a) and 5.7(1)(a), respectively, of MI 61-101, as neither the fair market value of the securities issued to the related parties, nor the fair market value of the consideration for the securities issued to the related parties exceeds 25 per cent of the corporation's market capitalization as calculated in accordance with MI 61-101. The corporation did not file a material change report more than 21 days before the expected closing date of the offering as the aforementioned insider participation had not been confirmed at that time and the corporation wished to close the offering as expeditiously as possible.

The offering was made by way of private placement in each of the provinces of Canada pursuant to applicable exemptions from the prospectus requirements and, in the case of the common shares, in certain other jurisdictions, in each case in accordance with all applicable laws. The offering of the common shares was conducted on a private placement basis to persons in the United States who are accredited investors as such term is defined in Rule 501(a) of Regulation D under the U.S. Securities Act of 1933, as amended, and in compliance with Rule 506(b) of Regulation D and applicable United States securities laws.

The offering is subject to final acceptance of the TSX Venture Exchange.
