TRIMERA METALS COMMENCES FIELD ACTIVITIES AT TAHLO LAKE PROPERTY, BRITISH COLUMBIA

Trimera Metals Corp. has provided an update on proposed exploration activities for its 1,692.22-hectare Tahlo Lake porphyry copper-molybdenum-gold property located in north-central British Columbia.

The property is located approximately 11 kilometres to the northeast of American Eagle Gold Corp.'s NAK project, where drilling has identified numerous long high-grade intervals of copper-gold mineralization. The property is within a prospective belt of rocks known as the Babine porphyry copper belt. This belt, measuring roughly 20 km by 80 km on the east side of Babine Lake, hosts many copper-rich mineral deposits at varying stages of development, from notable occurrences to developed prospects to past-producing mines. The property is at the northern end of this prospective belt of rocks.

Readers are cautioned that the geology of nearby properties is not necessarily indicative of the geology of the property.

Field crews have been mobilized to the property, with exploration activities commencing on Sept. 4. Initial work includes geological mapping, rock and basal glacial till sampling, and prospecting. This fieldwork is expected to be completed by Sept. 12.

Initial preparation work has already been carried out, including the acquisition of a light detection and ranging survey, a draft surficial geology map, and an interpretation of last year's ZTEM.

Patrick Donnelly, chief executive officer of Trimera, stated: "We are excited to finally get some boots on the ground for our inaugural field season at Tahlo Lake, which we believe has some compelling geological features that indicate the potential for porphyry copper-gold mineralization. I look forward to receiving initial results of our work, which may allow us to proceed to a drilling campaign."

The company also wishes to correct a typographical error in its Aug. 26, 2025, news release. Whereas the prior release referenced the company's new trading symbol on the OTCQB as TRMFF, the company's symbol on the OTCQB is TRMMF.
