Trimera Metals Completes 2025 Tahlo Lake Exploration Program

Executive Summary

• Trimera Metals reported significant progress on its 2025 Tahlo exploration program, including completion of ZTEM data interpretation and acquisition of LiDAR survey data.
• A seven‑day till sampling campaign (Sept 2‑8, 2025) collected 20 samples from 14 hand‑dug pits; assays are pending and expected within the next month.
• The company highlighted the strategic location of the Tahlo Lake property adjacent to American Eagle’s NAK project, underscoring its potential for porphyry copper‑gold mineralization.

Key Details

• Geophysical work: Completed interpretation of Z‑Axis Tipper Electromagnetic (ZTEM) survey data in August 2025, identifying several prospective areas of interest (AOIs).
• LiDAR acquisition: Obtained Light Detection and Ranging data to produce a preliminary surficial geology map used for target selection.
• Till sampling program: Conducted from 2–8 Sept 2025; four samplers collected 20 samples across 14 hand‑dug till pits within the AOIs.
• Sample handling: All samples were delivered to ALS preparation laboratory in Terrace, BC on 10 Sept 2025 for assay.
• Assay timeline: Results are anticipated within one month of delivery; a few additional rock samples remain to be submitted for analysis.
• Strategic context: Property lies ~11 km from American Eagle’s NAK project, which has demonstrated copper‑gold porphyry mineralization, suggesting similar potential at Tahlo Lake.
• Qualified Person: Patrick Donnelly, P.Geo., President & CEO, reviewed and approved the technical information under NI 43‑101.
