OMINECA PROVIDES OPERATIONAL UPDATE OF PLACER GOLD RECOVERY AT WINGDAM

Omineca Mining and Metals Ltd. has provided an operational update from the Wingdam underground paleoplacer project located in the Cariboo mining district of south-central British Columbia. The company's mining contractor D&L Mining has reported the following.

Following the year-end holiday break, tunnelling and placer recovery operations have recommenced at crosscut 3A. Additional time was given to tunnelling through a fault zone at the channel periphery. Modified grout formulations and spiling patterns were implemented, allowing operations to return to standard tunnelling and excavation procedures. Having safely managed the faulted ground conditions, D&L anticipates the tunnelling and excavation will proceed at an increased pace within the more competent compacted sand and gravel of the channel interior.

As expected, pay gravels excavated from the initial advance into the channel interior have yielded increasing amounts of placer gold and nuggets compared with the earlier bedrock contact zone (see news release dated Dec. 5, 2025).

Placer gold recoveries will be fully tabulated, subject to quality assurance and quality control by a qualified person and reported as the crosscut makes its way through the central main placer gold target and through to the opposite side of the channel.

Exploration program

Separate from the underground placer project, approximately 3,500 metres of core from six holes drilled during the 2025 winter drill program has been logged and split and samples sent in for assay. Results will be reported once they are received with a drill program to be designed to follow up on these results.

About Omineca Mining and Metals Ltd.

Omineca's flagship Wingdam gold exploration and placer recovery projects are located along the Barkerville Highway 45 kilometres east of the city of Quesnel. The Wingdam property includes mineral tenures totalling over 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 an exploration and diamond drill program currently under way exploring for the potential multiple hardrock sources of the placer gold at Wingdam.
