OMINECA UPSIZES PRIVATE PLACEMENTS TO $1,300,000

Omineca Mining and Metals Ltd. has increased the size of its previously announced concurrent non-brokered private placements of aggregate gross proceeds of up to $1-million to an upsized $1.3-million on the same terms.

The offerings will now consist of: (i) 14,702,000 common share units of the company at a price of five cents per unit for gross proceeds of $735,100; and (ii) 9,414,998 flow-through units of the company at a price of six cents per flow-through unit for gross proceeds of approximately $564,900. All other terms of the offerings remain unchanged from those disclosed in the company's Sept. 10, 2026, news release.

Closing of the offerings remains subject to the acceptance of the TSX Venture Exchange and other customary closing conditions.

Certain insiders of the company are participating in the offerings. Such participation constitutes a related party transaction within the meaning of Multilateral Instrument 61-101, Protection of Minority Security Holders in Special Transactions. The company is relying on the exemptions from the formal valuation and minority shareholder approval requirements of MI 61-101 contained in sections 5.5(a) and 5.7(1)(a) of MI 61-101, as neither the fair market value of the securities to be issued to, nor the consideration to be paid by, insiders exceeds 25 per cent of the company's market capitalization. The company did not file a material change report more than 21 days before the expected closing date of the offerings, as the details of insider participation had not been confirmed at that time and the company wishes to close the offerings on an expedited basis for sound business reasons.

About Omineca Mining and Metals Ltd.

Wingdam, British Columbia

Omineca's flagship Wingdam hard rock exploration and placer gold recovery projects are located along the Barkerville Highway, 45 kilometres east of the city of Quesnel. The Wingdam property includes mineral tenures totalling 61,392 hectares (613 square kilometres) and in excess of 15 linear kilometres of placer claims, both encompassing the Lightning Creek valley, where topographic conditions created thick layers of overburden, which preserved a large portion of a buried paleochannel containing placer gold-bearing gravels. Omineca also has a program exploring for the potential multiple hard rock sources of the placer gold at Wingdam.

Fraser Canyon, British Columbia

Part of Omineca's original acquisitions in the Cariboo mining district, the Fraser Canyon project, located 12 kilometres northwest of Quesnel, B.C., is now slated to reinitiate the development of the underground paleochannel for the recovery of placer gold. Historically, two mines north and south of the Fraser River collectively produced 1,482 ounces of raw placer gold.
