TRIMERA METALS COMPLETES 2025 TAHLO LAKE EXPLORATION PROGRAM

Trimera Metals Corp. has made significant progress on its 2025 Tahlo program, a key exploration initiative on its wholly owned Tahlo Lake property, located 11 kilometres from American Eagle Gold Corp.'s promising Nak project in British Columbia. The company continues to leverage advanced geophysical and geological techniques to identify high-potential mineral targets in this highly prospective region.

In August, 2025, Trimera completed the interpretation of data from a ZTEM (Z-axis tipper electromagnetic) survey, which delineated several prospective areas of interest (AOIs). Concurrently, the company acquired light detection and ranging (lidar) survey data, enabling the creation of a preliminary surficial geology map. This map was instrumental in guiding the selection of sample sites within and down-ice of the AOIs, targeting surficial polygons deemed suitable for till pitting.

From Sept. 2 to Sept. 8, 2025, a seven-day till sampling program was conducted. A team of four samplers collected 20 samples from 14 hand-dug till pits. These samples were delivered to the ALS preparation laboratory in Terrace, B.C., on Sept. 10, 2025. Assay results are anticipated within the next month, with a few additional rock samples still to be submitted for analysis.

Background on Tahlo Lake property

As highlighted in Trimera's Sept. 5, 2025, press release, the property is strategically located in a region known for its significant mineral potential, underscored by its proximity to American Eagle's Nak project, which has demonstrated promising copper-gold porphyry mineralization. The property encompasses favourable geological settings conducive to hosting similar mineral systems, and Trimera's systematic exploration approach aims to unlock its potential.

"We are excited about the progress of the 2025 Tahlo program and its potential to uncover significant mineralized zones in this highly prospective region," said Patrick Donnelly, president and chief executive officer of Trimera. "Our proximity to American Eagle's Nak project further underscores the strategic importance of the property, and we eagerly await the assay results to guide our next steps."

Trimera remains committed to advancing its exploration programs through innovative and sustainable practices, positioning the company to create value for its shareholders in one of British Columbia's most exciting mineral districts.
