Berg Project advances toward pre-feasibility after Surge Copper's 2025 drilling and data validation program

Surge Copper completed a 2025 multidisciplinary drilling and data-validation program at the 100%-owned Berg Project, recording 4,143 metres of diamond drilling and resampling 17 historic core holes. The article reports the work is intended to support a Pre-Feasibility Study planned for H1 2026.

Surge Copper carried out a focused 2025 field program at its 100%-owned Berg Project in central British Columbia to provide technical data for a planned Pre-Feasibility Study. The program combined fresh drilling, resampling of historic core, geotechnical work, and environmental characterization. Work aimed to increase confidence in the database, test for acid-generating rock within the waste envelope, and gather parameters needed for mine infrastructure design. The company reports the program was executed to support a resource update and the PFS schedule. Key facts: - The 2025 program completed a total of 4,143 metres of diamond drilling, comprising 4 resource conversion holes (1,926 m), 4 acid rock drainage characterization holes (1,522.6 m), 11 geotechnical holes (618.4 m) and 3 short anchor holes (76 m). - Seventeen historic core holes drilled between 1964 and 1973 were resampled and assayed using modern methods, increasing the Berg database to 26,797 unique assay intervals and raising the share of samples with gold and silver analyses to about 82.6% (22,138 samples). - The four resource conversion holes intersected continuous porphyry-style mineralization along deposit margins; hole BRG25-259 returned 235 metres at 0.31% copper equivalent and BRG25-260 returned 279 metres at 0.20% copper equivalent, as reported. - The acid rock drainage (ARD) program delineated mineralized and altered rock beyond the interpreted pyrite halo; preliminary static tests indicate a transition toward non-acid-generating rock with distance from the deposit center, and representative samples were submitted for longer-term humidity cell testing. - Geotechnical work included detailed logging, laboratory strength testing, standard penetration and packer tests, installation of vibrating wire piezometers, and 20 seismic refraction lines to map overburden and bedrock conditions for infrastructure design. Summary: The article reports these 2025 drilling and data-validation activities are intended to support a mineral resource update and advance Berg from PEA-level study work toward a Pre-Feasibility Study planned for H1 2026. The company describes the results as improving confidence in historic data, adding precious metal assays, informing waste rock acid-base characterization, and providing geotechnical inputs for planned mine infrastructure. The forthcoming resource update and PFS will use the new database and test results to refine project technical work and classification.
