Red Cloud Securities Inc. acted as lead underwriter and sole bookrunner, on behalf of a syndicate of underwriters that included Haywood Securities Inc., SCP Resource Finance LP and Eight Capital (collectively, the "Underwriters").

Each FT Unit consists of one common share of the Company (each, a "Common Share") issued as a "flow-through share" within the meaning of the Income Tax Act (Canada) (each, a "FT Share") and one half of one Common Share purchase warrant (each whole warrant, a "Warrant"). Each whole Warrant shall entitle the holder to purchase one Common Share (a "Warrant Share") at a price of C$0.485 per Warrant Share at any time on or before September 12, 2025.

The expenditures to be renounced in respect of the Common Shares comprising the FT Units will be used for "Canadian Exploration Expenses" (within the meaning of the Income Tax Act (Canada)) (the "Tax Act") and will qualify as "flow-through critical mineral mining expenditures" as defined in subsection 127(9) of the Tax Act and a "flow-through mining expenditure" as defined in paragraph 2(2)(d) of The Mineral Exploration Tax Credit Regulations, 2014 (Saskatchewan) (the "Qualifying Expenditures"). The Qualifying Expenditures will be renounced to the purchasers of the FT Units with an effective date no later than December 31, 2023.

The securities issued pursuant to the Offering are subject to a four-month and one day hold period ending on January 13, 2024.

In connection with the Offering, the Company paid to the Underwriters an aggregate cash commission of C$1,086,250, equal to 5.50% of the gross proceeds raised under the Offering (except for gross proceeds raised from the sale of FT Units sold to purchasers on a president's list (the "President's List"), which was subject to a reduced 2.75% cash commission).
