The gross proceeds received by the Company from the sale of the FT Shares will be used to incur Canadian exploration expenses that are "flow-through mining expenditures" (as such terms are defined in the Income Tax Act (Canada)) on the Company's properties in Saskatchewan (the "Qualifying Expenditures"). The Qualifying Expenditures will be renounced to the subscribers with an effective date no later than December 31, 2020, in the aggregate amount of not less than the total amount of the gross proceeds raised from the issue of FT Shares.

The closing of the Offering is anticipated to occur on or about December 22, 2020 (the "Closing Date") and is subject to certain conditions including, but not limited to, the receipt of all necessary regulatory approvals, including the acceptance of the TSX Venture Exchange.

The FT Shares will be offered by way of a private placement pursuant to exemptions from the prospectus requirements to residents of all of the provinces of Canada and such other jurisdictions as may be agreed to by the Company and the Underwriter.

All securities issued under the Offering will be subject to a statutory hold period in Canada expiring four months and one day from the date of issuance.
