The Company will use the gross proceeds from the issue and sale of the FT Shares and Charity FT Units to incur eligible "Canadian exploration expenses" that qualify as "flow-through critical mineral mining expenditures" as both terms are defined in the Income Tax Act (Canada) (the "Qualifying Expenditures") on the Company's flagship Roger Project, located in the Chibougamau district in Quebec.. The Qualifying Expenditures are to be incurred on or before December 31, 2026, and the Company will renounce all the Qualifying Expenditures in favour of the subscribers of the FT Shares and Charity FT Units effective December 31, 2025.

In connection with the Offering, the Company paid certain persons ("Finders") finders' fees consisting of cash payments of up to $219,257, representing up to 7% of the aggregate proceeds raised by the Finders, and up to 2,311,353 non-transferable warrants ("Finder's Warrants"), representing up to 7% of the number of FT Units and Charity FT Units sold to subscribers introduced to the Company by the Finders.
