(TheNewswire)

SASKATOON, SK – February 19, 2026 – Omineca Miningand Metals Ltd. (TSXV: OMM) ("Omineca" or the"Company") is pleased to provide an operational update fromthe Wingdam underground paleoplacer project located in the CaribooMining District of south central British Columbia. The Company’smining contractor, D&L Mining reports:

Following the year-end holiday break, tunnelling andplacer recovery operations have recommenced at crosscut 3A. Additionaltime was given to tunnelling through a fault zone at the channelperiphery. Modified grout formulations and spiling patterns weresuccessfully implemented allowing operations to return to standardtunnelling and excavation procedures. Having safely managed thefaulted ground conditions, D&L anticipates the tunnelling, andexcavation will now proceed at an increased pace within the morecompetent compacted sand and gravel of the channel interior.

As expected, pay gravels excavated from the initial advance into the channel interiorhave yielded increasing amounts of placer gold and nuggets compared tothe earlier bedrock contact zone (see news release dated December 5,2025 and photos below).

Placer gold recoveries will be fully tabulated, subjectto quality assurance and quality control by a Qualified Person andreported as the crosscut makes its way through the central main placergold 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 the2025 winter drill program has been logged, split and samples sent infor assay. Results will be reported once they are received with adrill program to be designed to follow up on these results.
