Saskatoon, Saskatchewan – TheNewswire - October 27, 2026 – Omineca Mining and Metals Ltd. (TSXV: OMM) (“Omineca” or the “Company”) is pleased to announce that in the matter of the declared, voluntary bankruptcy of D&L Mining Corp (see news release October 9th , 2026),  the Licensed Insolvency Trustee, MNP Ltd., has disclaimed/quit claimed D&L’s interest in the Wingdam underground project.

Since receiving this notice, Omineca has taken steps to secure management of the mine site in order to provide continuity of operations.  In support of these measures, Omineca has engaged PSI Mining of Saskatoon, Saskatchewan to assume temporary operating responsibility for the Wingdam placer project.

This significant outcome returns full control of the Wingdam Paleoplacer project to Omineca, allowing management to complete an agreement directly with a development partner prepared to advance the project without delay.

About Omineca Mining and Metals Ltd.

Wingdam, BC

Omineca’s flagship Wingdam hard rock exploration and placer gold recovery projects are located along the Barkerville Highway 45 km east of the City of Quesnel. The Wingdam Property includes mineral tenures totaling 61,392 hectares (613 square kms) and in excess of 15 linear kilometers 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, BC

Part of Omineca’s original acquisitions in the Cariboo Mining District, the Fraser Canyon Project located 12 kilometers northwest of Quesnel, BC, 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 oz of raw placer gold.
