Toronto, Ontario, November 18, 2025 – Silver Mountain Resources Inc . ("Silver Mountain " or the

"Company") (TSXV: AGMR) is pleased to announce that it has completed its previously announced

prospectus offering (the "Offering") of units of the Company (the "Units"). The Offering was completed on

a "bought deal " basis pursuant to an underwriting agreement (the " Underwriting Agreement" ) dated

November 12, 2025 as amended on November 17, 2025, among the Company and a syndicate of

underwriters comprising Velocity Capital Partners, as sole bookrunner, and as co- lead underwriters with

SCP Resource Finance LP, together with Research Capital Corporation and Stifel Nicolaus Canada Inc

11,500,000 Units at a price of $2 .60 per Unit for aggregate gross proceeds of $ 29,900,000, including the

full exercise by the Underwriters of their over-allotment option.

Each Unit was comprised of (i) one class A common share of the Co mpany (each, a "Common Share"),

(ii) one-half of one 6- month Common Share purchase warrant ( each whole 6- month Common Share

purchase warrant, a "Series A Warrant "), and (iii) one-half of one 24- month Common Share purchase

warrant (each whole 24- month Common Share purchase warrant, a "Series B Warrant"). Each Series A

Warrant entitles the holder thereof to acquire one Common Share at an exercise price of $3.25 per Common

Share, subject to customary anti -dilution adjustments, until May 18, 2026, and each Series B Warrant

entitles the holder thereof to acquire one Common Share at an exercise price of $3.90 per Common Share,

subject to customary anti -dilution adjustments, until November 18, 2027. The Series A Warrants and the

Series B Warrants are each governed by warrant indentures dated November 18, 2025 between the

Company and Odyssey Trust Company, as warrant agent.

The Company intends to use the net proceeds from the Offering to conduct exploration activities on its

mineral properties, capital improvements to the plant and infrastructure to increase / maximize production

capacity, and for working capital and general corporate purposes.

In connection with the Offering, the Underwriters received a cash commission equal to 6.0% of the gross

proceeds from the sale of the Units (reduced to 3.0% for the gross proceeds in respect of sales to certain

investors on a president's list) in the aggregate amount of approximately $1,643,903.

The Offering was completed by way of a prospectus supplement (the "Supplement") dated November 12,

2025 to the short form base shelf prospectus of the Company dated October 16, 2025 (the " Base Shelf"),

in each of the provinces and territories of Canada, other than Québec, and in jurisdictions outside Canada

pursuant to exemptions from prospectus and registration requirements.

Certain directors of the Company (each, an "Insider") purchased an aggregate of 1,138,500 Units pursuant

to the Offering. Each subscription by an Insider is considered to be a "related party transaction" for the

purposes of Multilateral Instrument 61-101 – Protection of Minority Security Holders in Special Transactions

("MI 61-101"). The Company did not file a material change report more than 21 days before the expected

closing date of the Offering as the details of the Offering and the participation therein by each "related party"

of the Company were not settled until shortly prior to the closing of the Offering, and the Company wished

to close the Offering on an expedited basis for sound business reasons. The Company is relying on

exemptions from the formal valuation and minority shareholder approval requirements available under MI

61-101. The Company is exempt from the formal valuation requirement in S ection 5.4 of MI 61- 101 in

reliance on section 5.5(a) of MI 61- 101 as the fair market value of the transaction, insofar as it involves

interested parties, is not more than 25% of the Company's market capitalization. Additionally, the Company

is exempt from minority shareholder approval requirement in Section 5.6 of MI 61-101 in reliance on Section

5.7(1)(a) of MI 61-101 as the fair market value of the transaction, insofar as it involves interested parties, is

not more than 25% of the Company's market capitalization.

The Offering is subject to the final approval of the TSX Venture Exchange.

The securities offered pursuant to the Offering have not been, and will not be, registered under the U.S.

Securities Act of 1933, as amended (the "U.S. Securities Act") or any U.S. state securities laws, and may

not be offered or sold in the United States or to, or for the account or benefit of, United States persons

absent registration or any applicable exemption from the registration requirements of the U.S. Securiti es

Act and applicable U.S. State Securities Laws. .
