NEWS RELEASE
Surge Copper Evaluates Energy-Saving HPGR Technology for Berg Project
April 15, 2025, Vancouver, British Columbia – Surge Copper Corp. (TSXV: SURG) (OTCQB:
SRGXF) (Frankfurt: G6D2) (“Surge” or the “Company”) is pleased to highlight results from an
industrial energy efficiency study investigating the potential benefits of incorporating high-
pressure grinding rolls (“HPGR”) into the comminution circuit at its Berg Project in central British
Columbia. The study, conducted by Ausenco Engineering Canada ULC with input and support
provided by BC Hydro , evaluates the energy efficiency impacts of an HPGR -based circuit
compared to a traditional semi -autogenous grinding (“SAG”) and ball milling configuration. The
study incorporates updated breakage test work data from the ongoing metallurgical test program
conducted by ALS Metallurgy Kamloops (“ALS”).
Study Highlights
• Laboratory comminution tests confirm the amenability of Berg mineralized material to
HPGR technology.
• The HPGR configuration has the potential to reduce grinding power requirements by
approximately 25% compared to a comparable baseline SAG milling configuration.
• Overall annual energy consumption in the grinding circuit may be reduced by
approximately 20% with the HPGR configuration.
Leif Nilsson, Chief Executive Officer, commented: “ We are pleased to see early indications that
HPGR could be a viable option for improving energy efficiency at Berg. While many trade -off
studies remain ahead of us, this data suggests that alternative milling configurations may provide
additional strategic flexibility as the project advances. Power supply is often a primary bottleneck
for large -scale milling operations at porphyry copper mines, so evaluating options that could
reduce energy demand is an important aspect of our project planning.”
The study provides a conceptual-level assessment of the energy use and operating cost benefits
of an HPGR circuit while recognizing the potential for offsetting capital costs relative to a traditional
SAG milling configuration. The study does not directly consider additional factors such as
environmental impact, carbon footprint, or regional energy supply dynamics over the life of the
project. Given these additional considerations , further trade -off analysis is warranted as the
Surge Copper Corp. 2
Company progresses its technical studies toward a potential pre-feasibility assessment, ensuring
a comprehensive evaluation of project development options.
Additional Updates on the Berg Project
• The ALS metallurgical test program is progressing well and nearing completion, with
results expected to be reported in a future update.
• Results from six additional core holes drilled during the 2024 program for downhole
geotechnical analysis will be reported following completion of laboratory analysis and
reporting, expected in the coming weeks.
• Planning and preparations for the 2025 field program are underway, with details to be
provided once finalized.

About Surge Copper Corp.
Surge Copper Corp. is a Canadian company that is advancing an emerging critical metals district
in a well-developed region of British Columbia, Canada. The Company owns a large, contiguous
mineral claim package that hosts multiple advanced porphyry deposits with pit-constrained NI 43-
101 compliant resources of copper, molybdenum, gold, and silver – metals which are critical
inputs to modern energy infrastructure and electrification technologies.
The Company owns a 100% interest in the Berg Project, for which it announced a maiden PEA
in June 2023 outlining a large -scale, long-life project with a simple design and high outputs of
critical minerals located in a safe jurisdiction near world -class infrastructure. The PEA highlights
base case economics including an NPV8% of C$2.1 billion and an IRR of 20% based on long -
term commodity prices of US$4.00/lb copper, US$15.00/lb molybdenum, US$23.00/oz silver, and
US$1,800/oz gold. The Berg deposit contains pit-constrained 43 -101 compliant resources of
copper, molybdenum, silver, and gold in the Measured, Indicated, and Inferred categories.
The Company also owns a 100% interest in the Ootsa Property, an advanced -stage exploration
project containing the Seel and Ox porphyry deposits located adjacent to the open pit Huckleberry
Copper Mine, owned by Imperial Metals. The Ootsa Property contains pit-constrained NI 43-101
compliant resources of copper, gold, molybdenum, and silver in the Measured, Indicated, and
Inferred categories.
