Silver Dollar Resources Proposes Warrant Expiry Extension

VANCOUVER, BC – September 22, 2026 – Silver Dollar Resources Inc. (CSE: SLV) (OTCQX: SLVDF) (FSE: 4YW) (“Silver Dollar” or the “Company”) announces it intends to extend the expiry date of 3,022,600 share purchase warrants (the “Warrants”) from October 29, 2026 to October 29, 2027 (the “Proposed Extension”), subject to acceptance by the Canadian Securities Exchange (the “CSE”), as applicable, the agreement of the holders and compliance with applicable securities laws.

The Warrants were issued on October 29, 2024 as part of a non-brokered private placement of 6,000,000 units priced at $0.25 each. The units comprised one common share and one-half of a non-transferable share purchase warrant with each full warrant entitling the holder to purchase one additional common share of the Company at a price of $0.40 per share for, originally, two years from the closing date of the offering. In conjunction with the offering, the Company also issued 89,600 warrants on the same terms in respect of finders’ fees.

Pursuant to the Proposed Extension, the exercise price and all other terms of the Warrants remain unchanged. The closing price of the Company’s common shares on the CSE on September 21, 2026 was $0.27.

The Proposed Extension will become effective on the closing date determined by the Company following receipt of CSE acceptance, as applicable, and the required holder agreements, accredited investor representations and other confirmations required by the Company for purposes of applicable securities laws. A holder that does not satisfy these conditions will not receive the benefit of the Proposed Extension, and the Warrants held by that holder will continue to expire on October 29, 2026 in accordance with their existing terms.

The Proposed Extension will constitute a new distribution of the Warrants under applicable Canadian securities laws. The Company intends to rely on the accredited investor exemption from prospectus requirements in connection with the Proposed Extension. The Warrants, as amended, and any common shares issued upon exercise thereof will be subject to a statutory hold period of four months and one day from the effective date of the Proposed Extension, in accordance with applicable Canadian securities laws. Any proceeds from the exercise of the Warrants will be used for general working capital purposes.

The Company will rely on subsections 5.5(b) and 5.7(1)(a) of Multilateral Instrument 61-101 to exempt the Proposed Extension from the requirements for a formal valuation and minority shareholder approval. To the Company’s knowledge, neither it nor the purchasers have knowledge of any material information concerning the Company or its securities that has not been generally disclosed.
