NEWS RELEASE
Surge Copper Advances Berg Toward Pre-Feasibility with Successful 2025 Drilling and
Data Validation Program
January 8, 2026 – Vancouver, British Columbia – Surge Copper Corp. (TSXV: SURG)
(OTCQB: SRGXF) (Frankfurt: G6D2) (“Surge” or the “Company”) is pleased to report
results from its 2025 multidisciplinary drilling and field program at the 100%-owned Berg
Project in central British Columbia. The program was designed to advance Berg toward
completion of a Pre-Feasibility Study (“PFS”) planned for H1-2026 (see November 19, 2025
press release ), and was successfully executed with a focus on resource category
conversion, validation of historic drilling through modern QA/QC procedures, acid rock
drainage characterization, and geotechnical investigations for planned mine infrastructure.
Highlights
In 2025, Surge completed a focused multidisciplinary program to support a planned
2026 mineral resource update and PFS at Berg
Four infill drill holes targeting the outer margins of the deposit successfully
intersected continuous porphyry-style mineralization and are expected to support
conversion of Inferred resources to Measured and Indicated Categories
Historic core re-assaying has identified a meaningful silver component in the
northwest portion of the Berg deposit, where multiple holes now return long intervals
with elevated silver grades
Combined with 2025 infill drilling, these results increase copper-equivalent values in
an area targeted for resource category conversion and may positively impact future
resource estimates

Seventeen historic core holes were resampled using modern analytical methods and
QA/QC protocols, materially increasing confidence in the historical dataset and
enabling their use in future resource classification
Dedicated acid rock drainage and geotechnical drilling programs were successfully
completed providing critical environmental and engineering data required for mine
design and permitting
Leif Nilsson, Chief Executive Officer, commented: “The 2025 drill program at Berg delivered
the critical technical data required to advance the project toward pre-feasibility, including
information to support resource category upgrades, geotechnical design, and
environmental geochemistry studies, putting us well on track to complete the PFS on
schedule. I want to sincerely thank our exploration team and partners for executing this
complex program safely, efficiently, and with outstanding attention to detail. In addition to
achieving our technical objectives, the resampling of historic core has revealed a meaningful
precious metal component, particularly silver, in the northwest portion of the deposit,
enhancing copper-equivalent value and highlighting potential upside ahead of our next
resource update.”

Summary of the Berg Project 2025 Program
The 2025 field program was designed to address key technical data gaps required to
advance the Berg Project from a Preliminary Economic Assessment (“PEA”)-level study to
PFS, including improvements to resource confidence, geotechnical design parameters, and
environmental characterization. During the program, Surge completed a total of 4,143
metres of diamond drilling, comprising 4 resource conversion holes targeting upgrades of
Inferred resources (1,926 metres), 4 acid rock drainage (“ARD”) characterization holes
designed to define the boundary between potentially acid-generating and non-acid-
generating rock within the waste rock envelope surrounding Berg mineralization (1,522.6
metres), and 11 geotechnical drill holes completed in areas of planned project
infrastructure (618.4 metres). In addition, 3 short anchor holes were drilled to support the
ARD program; these holes were logged and sampled for assay and contribute an additional
76 metres of data to the Berg drill database.
In parallel with the drilling program, the Company resampled and assayed 17 historic Berg
core holes drilled between 1964 and 1973. The objective of this work was to apply modern
analytical methods and QA/QC procedures to increase confidence in the historical dataset,
add gold and silver analyses that were previously unavailable, and enable these holes to be
incorporated into future resource classification.
Geotechnical investigations focused on characterizing soil and rock properties relevant to
mine infrastructure design and ground stability in support of the ongoing PFS. Fieldwork
included detailed geotechnical logging, collection of samples for laboratory strength testing
and physical property measurements, standard penetration tests, packer tests, and
installation of vibrating wire piezometers. In addition, 20 seismic refraction geophysical
survey lines were completed to map overburden thickness, depth to bedrock, and measure
shear and compressional wave velocities for geotechnical design applications. Baseline
environmental studies also continued in 2025, including additional fish and fish habitat
assessments, installation of hydrometric stations to collect water flow data, and ongoing
water sampling.

Resource Conversion Holes
Four resource conversion holes, BRG25-257 to 260, totaling 1,926 metres of drilling, were
drilled along the western and southwestern margins of the Berg deposit with the objective
of upgrading Inferred resources to Measured and Indicated categories for inclusion in the
upcoming PFS. All holes were successfully drilled to their planned target depths and
intersected continuous porphyry-style alteration and mineralization. Mineralization extends
well below the conceptual PEA pit shell, supporting the continuity of the system at depth
and along its outer margins. As expected for these peripheral areas, grades are lower near
surface but increase at depth with all holes ending in strong mineralization below the PEA
pit boundary. Alteration and mineralization are characterized by quartz-anhydrite stockwork
veining containing pyrite-chalcopyrite-molybdenite associated with potassic and lesser
phyllic alteration.

1. Width refers to drill hole intercepts; true widths have not been determined. High grades have not been capped in the
averages.
2. CuEq (copper equivalent) is provided for illustrative purposes only to express the combined abundance of copper,
molybdenum, silver, and gold, with secondary metals calculated net of assumed metallurgical recoveries using
deposit average recovery assumptions from the PEA of 76% for molybdenum, 65% for silver, and 55% for gold. The
calculation uses metal prices of US$4.00/lb copper, US$15.00/lb molybdenum, US$23.00/oz silver, and
US$1,800/oz gold resulting in the formula: CuEq [%] = Cu [%] + 2.85 x Mo [%] + 0.0055 x Ag [g/t] + 0.3609 x Au [g/t].
Hole BRG25-259, located on the far western margin of the Berg deposit, intersected a
sequence of andesite and intrusive porphyry units and returned 235 metres grading 0.31%
copper equivalent (0.19% copper, 0.025% molybdenum, 8.61 g/t silver, and 0.016 g/t gold)
from 278 metres depth to the end of the hole at 513 metres depth.
Hole BRG25-259 was drilled within a large volume of Inferred resources in the current
resource model. This hole, together with the resampling of holes BRG013, BRG098 and
BRG079, is expected to support the conversion of a significant volume of Inferred resources
to the Measured and Indicated categories in the forthcoming resource update. The results
from BRG25-259, combined with increased copper-equivalent values in historic holes
following the addition of silver and gold assays, also indicate potential for higher-grade
resource extensions toward the western portion of the deposit.

location.
Hole BRG25-260, located on the northwestern margin of the Berg deposit, intersected
predominantly andesite and returned 279 metres grading 0.20% copper equivalent (0.16%
copper, 0.007% molybdenum, 2.51 g/t silver, and 0.016 g/t gold) from 132 metres depth to
the end of the hole at 411 metres depth.
Hole BRG25-260, together with the resampling of historic holes BRG083 and BRG079, was
designed to support conversion of a strip of Inferred resources along the western edge of the
deposit. In addition, resampling of hole BRG078 targeted conversion of a substantial zone
of Inferred resources within the lower-grade central portion of the Berg deposit.
