The Company will issue up to an additional 2,500,000 units (the "Additional Units") at a price of $0.40 per Additional Unit for additional gross proceeds of up to $1,000,000.

The Offering is being led by Research Capital Corporation and Eventus Capital Corp. as the co-lead agents and joint bookrunners, on behalf of a syndicate of agents, including Eight Capital (collectively, the "Agents").

Each Additional Unit will be comprised of one common share of the Company (a "Common Share") and one-half of one Common Share purchase warrant (each whole warrant, a "Warrant"). Each whole Warrant shall be exercisable to acquire one Common Share at a price of $0.55 per Common Share for a period of 24 months from the closing of the Offering.

The net proceeds of the Offering will be used for further exploration work on the Company's projects and for general working capital purposes.

In addition, the Company has granted the Agents an option (the "Agents' Option") to increase the size of the Offering by up to $900,000 by giving written notice of the exercise of the Agent's Option, or a part thereof, to the Company at any time up to 48 hours prior to closing of the Offering.

The Additional Units are expected to be offered to purchasers pursuant to the accredited investor exemption under section 2.3 of National Instrument 45-106 - Prospectus Exemptions and will be subject to a statutory hold period of four months and one day.

The Offering is anticipated to close on or about November 1, 2024, or such later date as the Company may determine. The closing is subject to certain conditions including, but not limited to, the receipt of all necessary regulatory and other approvals, including the approval of the TSX Venture Exchange.

In addition, the Company has agreed to issue to the Agents broker warrants of the Company exercisable for a period of 24 months, to acquire in aggregate that number of common shares of the Company which is equal to 7% of the number of Units sold under the Offering, subject to a reduction for orders on a "president's list", at an exercise price of $0.40.
