securities for sale in the United States

TORONTO, Sept. 23, 2026 -- Fredonia Mining Inc. (“Fredonia ” or the “Company”) (TSXV: FRED) is pleased to announce that

it has closed its previously announced “bought deal” private placement, pursuant to which it has issued an aggregate of

17,692,400 common shares of the Company (the “ Offered Shares ”) at a price of C$0.65 per Offered Share for aggregate

gross proceeds of C$11,500,060, which includes the full exercise of the underwriters’ option (collectively, the “Offering”).

The Company intends to use the net proceeds from the Offering for the exploration and advancement of the Company’s El

Dorado Monserrat Project in Santa Cruz province, Argentina, and for general corporate and working capital purposes, all as

further described in the offering document relating to the Offering.

The Offering was completed by a syndicate of underwriters led by ATB Cormark Capital Markets (the “Lead Underwriter ”), as

lead underwriter and sole bookrunner, and which included Canaccord Genuity Corp. (together with the Lead Underwriter, the

“Underwriters” and each individually, an “ Underwriter ”). In consideration for the services provided by the Underwriters in

connection with the Offering, the Company paid the Underwriters a cash commission equal to 6.0% of the gross proceeds of

the Offering, other than in respect of gross proceeds from sales to purchasers on the President’s List, for which a cash

commission equal to 3.0% of the gross proceeds was payable.

Directors and executive officers of the Company subscribed for a total of 500,000 Offered Shares in the Offering for aggregate

gross proceeds of C$325,000. The participation of insiders in the Offering constitutes a “related party transaction”, within the

meaning of the TSX Venture Exchange (the “Exchange”) Policy 5.9 and Multilateral Instrument 61-101 - Protection of Minority

Security Holders in Special Transactions (“MI 61-101”). The Company relied on the exemptions from the formal valuation and

minority shareholder approval requirements of MI 61-101 contained in sections 5.5(b) and 5.7(1)(b) of MI 61-101 in respect of

the related party participation in the Offering, which will be described in further detail in a material change report to be filed in

connection with the Offering that will be accessible under the Company’s profile on SEDAR+ at www.sedarplus.ca. The

material change report relating to the Offering will be filed less than 21 days prior to the closing date of the Offering. The

Company believes the shorter period was reasonable and necessary in the circumstances, as the typical lifecycle for a

transaction of this nature is significantly less than 21 days and the Company desired to act on an available financing

opportunity.

In accordance with National Instrument 45-106 Prospectus Exemptions (“NI 45-106 ”), the Offered Shares were issued to

purchasers resident in certain provinces of Canada pursuant to the “listed issuer financing exemption” (the “ Listed Issuer

Financing Exemption ”) under Part 5A.2 of NI 45-106, as amended by Coordinated Blanket Order 45-935 – Exemptions from

Certain Conditions of the Listed Issuer Financing Exemption . The Offered Shares issued to purchasers resident in Canada

pursuant to the Listed Issuer Financing Exemption are not subject to a four-month statutory hold period in Canada. The

Offered Shares were also offered in the United States by way of private placement pursuant to exemptions from the registration

requirements of the United States Securities Act of 1933, as amended (the “ U.S. Securities Act ”), and in certain other

jurisdictions outside of Canada and the United States on a private placement or equivalent basis, in each case in accordance

with all applicable laws. The Offered Shares were issued to purchasers outside of Canada pursuant to an exemption from the

prospectus requirements in Canada available under OSC Rule 72-503 – Distributions Outside Canada and, accordingly, the

Offered Shares issued to purchasers outside of Canada are not subject to a four-month statutory hold period in Canada. The

Offered Shares sold to officers and directors of the Company (as described above) are subject to a four-month hold period

pursuant to the rules of the Exchange, expiring January 24, 2027.

The Offering remains subject to final approval of the Exchange.

The securities described herein have not been, and will not be, registered under the U.S. Securities Act, or any U.S. state

securities laws, and may not be offered or sold to, or for the account or benefit of, persons in the “United States” or to “U.S.

persons” (as such terms are defined in Regulation S under the U.S. Securities Act), absent registration under the U.S.

Securities Act and all applicable U.S. state securities laws or in compliance with an exemption therefrom. This news release

does not constitute an offer to sell or a solicitation of an offer to buy nor shall there be any sale of any of the securities in any

jurisdiction in which such offer, solicitation or sale would be unlawful.

Update on Warrant Amendment Transaction

Pursuant to a news release dated December 17, 2025, the Company announced an intention to amend the exercise price of

4,818,932 outstanding warrants to purchase common shares at a price of $1.40 per common share (in the case of each of the

price and amount, on an effective, “post-consolidation” basis) to $0.45 per common share. The reduction remained subject to

warrantholder and Exchange approvals. As the Company has since the date of the announcement been able to complete

financing activity at a higher price per share in order to fund its operations and work programs at the EDM Project, the

Company announces it will withdraw its application and intention to proceed with the price reduction. The warrants will remain

outstanding and be exercisable in accordance with their terms at a price of $1.40 per share until April 27, 2027.
