Surge Battery Metals Reports Optimization of Flowsheet Parameters and Extraction Successes at Nevada North
Surge Battery Metals Reports Optimization of
Flowsheet Parameters and Extraction
Successes at Nevada North
West Vancouver, British Columbia--(Newsfile Corp. - May 26, 2026) - Surge Battery Metals Inc. (TSXV:
NILI) (OTCQX: NILIF) (FSE: DJ5) (the "
Company
" or "
Surge
") is pleased to provide an update on the
metallurgical testing program currently underway to support the Pre-Feasibility Study (PFS) by Nevada
North Lithium, LLC ("NNL"), the joint venture formed by Surge and Evolution Mining Limited ("Evolution")
to develop the Nevada North Lithium Project.
Concurrently with the successful development of the upgraded Mineral Resource Estimate (

Release May 14, 2026
), NNL's technical team has advanced flowsheet optimization in collaboration with
industry-leading metallurgical laboratories, including Kemetco Research Inc., Pocock Industrial Inc., and
Sepro Mineral Systems Corp.
Utilizing a representative Master Composite sample, NNL has successfully completed critical front-end
beneficiation and pre-leach optimization and is now initiating the next phase of testing designed to
confirm target recovery rates and de-risk solid-liquid separation.
Program Highlights & Upcoming Milestones:
Successful Beneficiation:
Beneficiation work—recently conducted on both the Master
Composite and variability samples—with Sepro has yielded positive results, demonstrating that
run-of-mine material can be effectively upgraded early in the flowsheet. Rejecting gangue material
before leaching is a critical driver for reducing downstream capital and operating expenditures.
Leach Circuit Optimization:
Ongoing testing at Kemetco has achieved lithium extraction rates
exceeding 93% under optimized leaching conditions. This favorable extraction rate reflects strong
alignment with Fluor's flowsheet modeling; the overall recovery rate—which incorporates
downstream performance—will be published in the forthcoming PFS report. By refining acid
addition and residence times, the team is maximizing extraction while minimizing impurities.
Scaled-up testing will conclude this month to generate slurry for downstream separation.
De-risking Solid-Liquid Separation:
Solid-liquid separation of clay-rich lithium material is a
technically challenging unit operation in the flowsheet due to fine particle size, clay rheology, and
material handling requirements. Early testing has already produced a physically stable filter cake
from beneficiated material. Next, Pocock will utilize Kemetco's scaled-up leach slurry to execute
advanced thickening, filtration and washing studies, providing the empirical data required for PFS
equipment selection.
Mr. Greg Reimer, President, Chief Executive Officer and Director of Surge, commented,
"Following the success of our recent resource upgrade, the commercial viability of our flowsheet is our
next priority. The beneficiation and pre-leach optimization work we have already executed has unlocked
early-stage efficiencies. Now, with initial testing at Kemetco achieving lithium extractions above 93%,
our planned larger-scale program with Pocock will provide the data needed to correctly size and design
our equipment."

About Surge Battery Metals Inc.
Surge Battery Metals Inc., a Canadian-based mineral exploration company, is at the forefront of securing
the supply of domestic lithium through its active engagement in the Nevada North Lithium Project. The
project focuses on development of high-grade lithium energy metals in Nevada, USA, a crucial element
for powering battery electric storage and electric vehicles. With a primary listing on the TSX Venture
Exchange in Canada and a listing on the OTCQX Market in the USA, Surge Battery Metals Inc. is
strategically positioned as a key player in advancing lithium exploration.
About Evolution Mining Limited
Evolution Mining Limited is a leading, globally relevant gold miner. Evolution operates six mines,
comprising five wholly-owned mines – Cowal in New South Wales, Ernest Henry and Mt Rawdon in
Queensland, Mungari in Western Australia, and Red Lake in Ontario, Canada, and an 80% share in
Northparkes in New South Wales.
About Nevada North Lithium, LLC
Nevada North Lithium, LLC, jointly owned by Surge Battery Metals Inc (70.54%) and Evolution Mining
Limited (29.46%), owns the Nevada North Lithium Project southeast of Jackpot, Nevada about 73 km
north-northeast of Wells, Elko County. The first four rounds of drilling at the project identified a strongly
mineralized zone of lithium bearing clays occupying a strike length of more than 4,700 meters and a
known width of greater than 2,000 meters. Highly anomalous soil values and geophysical surveys
suggest there is potential for the clay horizons to be much greater in extent. As disclosed in the
Company's Preliminary Economic Assessment dated May 19, 2025 (PEA), completed jointly by M3
Engineering & Technology Corp. and Independent Mining Consultants (see the Company's news release
dated July 24, 2025 for further information regarding the PEA), the Nevada North Lithium Project
reported an after-tax NPV8% US $9.17 Billion and after-tax IRR of 22.8% at $24,000/t LCE and an
OPEX of US $5,243/t LCE. The Project now has a pit-constrained Measured & Indicated Resource
containing an estimated 10.51 Mt of Lithium Carbonate Equivalent (LCE) grading 3007 ppm Li at a
1,250-ppm cutoff.
