Each Unit shall be comprised of one common share of the Company ("Common Share") and one half of one (1/2) Common Share purchase warrant ("Warrant") of the Company. Each whole Warrant shall entitle the holder thereof to acquire one additional Common Share at a price of $0.50 per Common Share for a period of three (3) years from the closing date (the "Closing Date") of the Offering.

The gross proceeds raised from Offering will be used: (i) to fund the US$700,000 option payment due on April 2, 2023 in respect of the Company's Tonopah West project; (ii) to fund the US$500,000 lease payment due on October 27, 2023 in respect of the Company's Silver Cloud project; (iii) for exploration of the Company's portfolio of silver and gold projects in Nevada; and (iv) for working capital and general corporate purposes.

All of the Units offered in the Offering shall be offered to purchasers pursuant to the listed issuer financing exemption under Part 5A of National Instrument 45-106 - Prospectus Exemptions and will not be subject to resale restrictions in Canada under applicable Canadian securities laws.

The Offering is anticipated to close on or about March 14, 2023, or such later date as the Company may determine. The closing is subject to certain conditions including, but not limited to, completion of the Minimum Offering and the receipt of all necessary regulatory and other approvals, including the approval of the TSX Venture Exchange.

The Company has agreed to pay the Agents a cash commission equal to 6.0% of the gross proceeds from the Offering and to issue the Agents warrants ("Compensation Warrants") equal to 6.0% of the aggregate number of Units issued under the Offering. The Compensation Warrants will be exercisable into Common Shares at a price per Common Share equal to the Offering Price for a period of three (3) years from the Closing Date.
