Omineca Provides Operational Update of Placer Gold Recovery at

Wingdam

SASKATOON, SK – February 19, 2026 – Omineca Mining and Metals Ltd. (TSXV: OMM)

("Omineca" or the "Company") is pleased to provide an operati onal 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 reports:

Following the year-end holiday break, tunnelli ng 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

successfully implemented allowi ng operations to return to standard tunnelling and

excavation procedures. Having safely m anaged the faulted gro und conditions, D&L

anticipates the tunnelling, and excavation will now 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 gol d and nuggets compared to the earlier bedrock

contact zone (see news release dated December 5, 2025 and photos below).

Placer gold recoveries will be fully tabulated , subject to quality assurance and quality

control by a Qualified Pers on 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 meters of core from

6 holes drilled during the 2025 winter drill program has been logged, split and samples

sent in for assay. Results will be reported once they are re ceived with a drill program to

be designed to follow up on these results.

About Omineca Mining and Metals Ltd.

Omineca Mining and Metals Ltd.’s flagship Wingdam gold exploration and placer recovery

projects are located along the Barkerville Highway 45 km east of the City of Quesnel. The

Wingdam Property includes mineral tenures totaling over 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 an exploration and diamond drill program currently underway

exploring for the potential multiple hard rock sources of the placer gold at Wingdam.
