West Vancouver, British Columbia--(Newsfile Corp. - June 9, 2025) - Surge Battery Metals Inc. (TSXV:

NILI) (OTCQX: NILIF) (FSE: DJ5) (the "

Company

" or "

Surge

") is pleased to report the results of its

2025 Preliminary Economic Assessment Study ("PEA") for the Nevada North Lithium Project ("NNLP")

located in Elko County north-northeast of Wells, Nevada.

The PEA, completed jointly by lead consultants M3 Engineering & Technology Corp. ("M3") and

Independent Mining Consultants ("IMC"), confirms robust economics for a low-cost, large-scale and long-

life conventional open pit and dry-stack tailings operation producing battery-grade lithium carbonate

through on-site treatment of the mined material processed through a sulfuric acid leaching circuit. The

PEA scenario envisions 2 phases over the initial 42-year mine life. Phase 1 includes 2.58 million tonnes

per annum ("Mtpa") processing throughput doubling to 5.15 Mtpa in Phase 2, which comes online in

Year 4 of production. A combination of the shallowest and highest lithium grades is prioritized for

processing, resulting in a variable battery-grade lithium carbonate production that peaks in Year 6 at

109,100 tonnes LCE, and averages 86,300 tonnes/year LCE for a total of 3.63 million tonnes LCE over

the LOM at a lithium recovery of 82.8%.

The PEA is derived using the inferred Mineral Resource Estimate ("MRE") effective as of October 9,

2024 and completed by Dr. Bruce Davis (the "MRE"). The effective date of the PEA is May 19, 2025,

and a NI-43101 compliant technical report (the "Technical Report") will be filed under the corporations

SEDAR+ profile within 45 days of this news release.

The preliminary economic assessment is preliminary in nature and includes inferred mineral resources

that are considered too speculative geologically to have the economic considerations applied to them

that would enable them to be categorized as mineral reserves.

There is no certainty that the preliminary

economic assessment will be realized.

Mineral resources that are not mineral reserves do not have

demonstrated economic viability.

The figures shown above represent the NNLP's potential economics with certain LCE selling price

assumptions.

The NNLP's sensitivity to LCE selling prices is detailed below in Table 2. To model 100%

ownership of the subsurface mineral rights on privately held land, Surge has assumed a 2% gross

revenue royalty in its economic model on all revenues from the private land.

Mr. Greg Reimer, Chief Executive Officer and Director, commented, "

We are ecstatic to present

the results of this PEA for the Nevada North Lithium Project. Our goal was to demonstrate that even

using best in class environmental practices, NNLP could potentially be a major low-cost producer of

battery-grade lithium carbonate for the United States battery industry, and we have taken a major step in

achieving that with today's results. The NNLP will benefit the local community with a long and stable 42-

year mine life, with significant extension potential, that will bring thousands of high paying jobs to

northeastern Nevada. Additionally, all of this is possible with a design that doesn't produce a tailings

pond. The combination of low OPEX, great ROI, and the ability to produce large quantities of battery-

grade lithium carbonate including a peak of 109,100 tonnes in one year showcases the Tier 1 status of

NNLP. We received the last assays from our initial drill program in January 2023 and are now reporting

an NPV of US$9.21 Billion in a period of 2.5 years. Our goal is to continue to advance and derisk the

NNLP at a rapid pace, and we hope for further improvements in the Pre-Feasibility and Feasibility

stages of development."

Project Details

The Nevada North Lithium Project is in Elko County in northern Nevada, USA. The Project is

approximately 73 kilometers (km) north-northeast of Wells, Nevada, 87 km west of the Utah Border and

35 km due south of the Idaho border. The Project is accessible via a paved highway and county-

maintained gravel roads with good regional infrastructure including power and rail. Northern Nevada is a

major hub for open pit mining operations and is recognized as one of the most concentrated areas in the

world for skilled mining labor. Nevada is home to experienced regulators where Federal and State of

Nevada agencies flow well-established protocols for hard rock mine permitting.

Drilling has identified a strongly mineralized zone of lithium bearing clays occupying a strike length of

more than 4,300 meters and a known width of greater than 1500 meters. The Nevada North Lithium

Project has a pit-constrained Inferred Resource containing an estimated 8.65 Mt of Lithium Carbonate

Equivalent (LCE) grading 2,956 ppm Lithium at a 1,250 ppm cutoff.

Mine Life & Production

The NNLP is planned as a simple truck and shovel operation that targets the shallow, high-grade

portions of the resource in the early mine life. A total of 205 Mt of mineralized material will be mined from

the open pit at an average lithium grade of 4,016 ppm. A total of 238 Mt of waste material will be

extracted, resulting in a low strip ratio of 1.16. The open pit operation will be executed in 14 pit phases

over 42 years, including 3 months of pre-production, with an owner-operated mining fleet.

Average LOM production of approximately 86,300 tonnes/year LCE for 42 years.

Figure 1 shows the lithium production and lithium grades in the plant feed and the post-

beneficiation leached lithium grade by Production Year.

The process is based on sulfuric acid leaching and industry standard techniques with a flowsheet

that produces a high-purity lithium carbonate that is subsequently upgraded to battery-grade in a

refining step. On-site acid production from elemental sulfur minimizes traffic to site, eliminates the

hazards of acid shipping, reduces the plant electricity demand, and ensures that best-in-class

environmental practices are employed.

Beneficiation is employed using Falcon 'C' Concentrators, which results in an average boost of

25% to the lithium grades prior to leaching (see

press release dated October 29, 2025

available

on the Company's SEDAR Profile).

total of US$2.97 Billion. The Phase 2 CAPEX is estimated to be US$2.35 Billion. Sustaining Capex is

estimated to total US$1.51 Billion over the LOM. The CAPEX is a Class 5 AACE estimate, and includes

offsite infrastructure, owner's cost and contingency.

The total Phase 1 construction period, including early works, commissioning and start-up is expected to

be 3.5 years. Phase 2 is expected to be a 3-year construction and commissioning schedule.
