In addition, the company has granted the agents an option to sell additional offered shares at the same issue prices for additional aggregate gross proceeds of up to $3,750,412, exercisable not later than 48 hours prior to the closing date (as defined below). The term offering includes the additional offered shares that may be issued on the exercise of the agents' option, if any.

The offering is anticipated to include participation from new and existing fundamental institutional investors and existing cornerstone shareholders.

Concurrent to the brokered offering, the company will conduct a non-brokered private placement of 4,762,000 NFT (non-flow-through) shares at a price of $1.05 per common share to raise up to $5,000,100. Wheaton Precious Metals Corp. has indicated its intention to subscribe in the non-brokered offering subject to entering into a right of first refusal agreement with NorthIsle, to be negotiated in good faith, and certain other conditions.

The company will use an amount equal to the gross proceeds received by the company from the sale of the CFT shares to incur eligible Canadian exploration expenses that qualify as flow-through critical mineral mining expenditures, as such terms are defined in the Income Tax Act (Canada). The company will incur the critical minerals qualifying expenditures on or before Dec. 31, 2026, and renounce (on a pro rata basis) all such expenditures in favour of the subscribers of the CFT shares with an effective date no later than Dec. 31, 2025, in accordance with the Income Tax Act (Canada). The proceeds from the sale of the NFT shares will be used for general corporate and working capital purposes as described in the offering document for the offering.

Closing is expected to occur on or about Aug. 8, 2025, or other such date as the company and the agents may agree. The offering is subject to regulatory approval, including the approval of the TSX Venture Exchange.

The offered shares will be offered for sale to purchasers resident in Canada, except Quebec, pursuant to the listed issuer financing exemption under Part 5A of National Instrument 45-106, Prospectus Exemptions, and in such other jurisdictions as may be mutually agreed upon by the agents and the company.
