Use of Proceeds

The gross proceeds received from the sale of the Flow-Through Shares and Charity Flow-Through Units will be used to incur Canadian exploration expenses ("CEE") as defined in subsection 66.1(6) of the Income Tax Act (Canada) (the "Tax Act") on the Company's Muus, Muus East, Nisk, Fancamp and Embry properties and renounced to subscribers in the Offering effective December 31, 2020. Such CEE will also qualify as "flow-through mining expenditures" as defined in subsection 127(9) of the Tax Act, and (i) for inclusion in the "exploration base relating to certain Québec exploration expenses" within the meaning contained in section 726.4.10 of the Taxation Act (Québec); and (ii) for inclusion in the "exploration base relating to certain Québec surface mining exploration expenses or oil and gas exploration expenses" within the meaning contained in section 726.4.17.2 of the Taxation Act (Québec). The net proceeds from the sale of the Units will be for the exploration of the Company's properties and for general working capital purposes.

Finders Fee Agreement

The Company has entered into an agreement (the "Agreement") with Red Cloud Securities Inc. (the "Finder") whereby the Company has agreed to pay a fee to the Finder in respect to those purchasers under the Offering introduced to the Company by the Finder. The Finder shall be be paid a cash payment equal to 7% of the gross proceeds received by the Company from purchasers under the Offering who were introduced to the Company by the Finder, with such fee representing a maximum of $157,500 paid by the Company to the Finder (the "Cash Finder's Fee"). In addition, the Company shall issue common share purchase warrants to the Finder in an amount equal to 7% of the common shares issued by the Company to purchasers under the Offering who were introduced to the Company by the Finder, with each such warrant entitling the Finder to acquire one common share for a period of 24 months following the closing of the Offering at a price of $0.10 per common share (the "Finder's Warrants").
