Imagine Lithium Highlights Robust Initial

Mineral Resource, Strong Metallurgy and

Upcoming Drill Program at Jackpot Property

Vancouver, British Columbia--(Newsfile Corp. - October 15, 2025) -

IMAGINE LITHIUM INC.

(TSXV:

ILI) (OTCQB: ARXRF)

(the "Company" or "Imagine")

is pleased to provide a summary of the

Company's most significant technical milestones at its 100%-owned Jackpot Lithium Project, located

near Thunder Bay, Ontario, Canada. The following highlights include the results of the recently completed

NI 43-101 compliant Mineral Resource Estimate (MRE), metallurgical test work, surface exploration

programs which identified new high-priority targets. Together with on-going and future exploration plans,

these milestones continue to demonstrate the project's strong potential as an open-pit, hard-rock lithium

deposit.

RESOURCE HIGHLIGHTS - NI 43-101 MINERAL RESOURCE ESTIMATE

Indicated Resource: 3.1 million tonnes grading 0.85% Li

O (26,200 t contained Li

O)

Inferred Resource: 5.3 million tonnes grading 0.91% Li

O (49,500 t contained Li

O)

Cut-off Grade: 0.30% Li

O (pit-constrained)

Recovery: 81.5% Li

O, based on SGS metallurgical testing

Bulk Density: 2.69 t/m³

Estimation Method: Inverse distance squared (ID²) on 2 × 2 × 2 m blocks

Effective Date: September 3, 2024; prepared by P&E Mining Consultants Inc.; technical

report filed October 18, 2024.

The MRE outlines two conceptual pit shells

— Jackpot and Casino Royale — both exhibiting good grade

continuity and strong potential for resource expansion. The resources remain open along strike and to

depth.

METALLURGICAL TEST WORK

The early metallurgical results demonstrate that Jackpot mineralization can yield a high-grade

spodumene concentrate suitable for the lithium battery supply chain.

Metallurgical testing was conducted by SGS Lakefield (2022-2023) on a 200 kg composite

sample grading 1.72% Li

O and 0.29% Fe

O

.

Heavy Liquid Separation (HLS) produced a 6.0% Li

O spodumene concentrate with 81.5% Li

O

recovery, and a concentrate iron content of 0.76% Fe

O

, without magnetic separation.

Additional optimization through dense media separation (DMS) and flotation is expected to further

enhance recovery and concentrate grade.

The Company adopted the 81.5% recovery figure within the MRE cut-off assumptions.

RECENT SURFACE EXPLORATION PROGRAMS

In addition to drilling, Imagine Lithium has completed a series of surface exploration programs to refine

targets across the Jackpot property:

Diamond Drilling: Resource expansion drilling west of the Jackpot pit shell intersected 0.92% Li2O

over 35.10m in hole JP-24-31;

Channel Sampling: Continuous channel sampling of exposed spodumene-bearing pegmatite

outcrops returned exceptional results including 65.10 m @ 1.10% Li

O, 10.3 m @ 1.23% Li

O

(including 4.0 m @ 2.88% Li

O), and 10.0 m @ 1.02% Li

O (including 6.0 m @ 1.56% Li

O).

These broad, high-grade channels confirm excellent surface continuity along multiple dykes within

the Jackpot Main Zone and the emerging Casino Royale area.

Prospecting: geological mapping and sampling has identified six new spodumene-bearing

pegmatite zones outside the current resource pit shells, all of which remain untested by drilling.

Soil Sampling: Over 1,200 soil samples collected on a 100 m × 50 m grid defined lithium-cesium-

tantalum (LCT) anomalies extending over 2 km northwest of the Main Zone.

Geophysics: High-resolution magnetic and LiDAR surveys have defined structural corridors and

parallel dyke trends coincident with known mineralization, providing new high-priority targets for

2026 drilling.

These surface programs expand the mineralized footprint well beyond the current pit-constrained

resource and highlight the potential for continued resource growth at both Jackpot and Casino Royale.

UPCOMING EXPLORATION PROGRAM AND NEXT STEPS

An aggressive 2026 exploration program is designed to expand known mineralization and test newly

identified targets:

Expansion drilling at both the Jackpot and Casino Royale zones to grow existing resources;

Drill test new targets (South Newkirk, South Jackpot and Cosgrave North zones) that were

discovered along the Jackpot - Casino open pit trend during the 2025 field season;

Complete a fall bedrock stripping and channel sampling program on the spodumene pegmatite

north of the historic Foster-Lew pegmatite;

Complete geological mapping and bedrock stripping on the newly discovered Blay Lake, Jackpot

West and Southwest zones;

Advance metallurgical optimization and preliminary engineering studies;

Initiate environmental baseline work and permitting preparations for future development.

QA/QC Protocol

Imagine Lithium implemented a strict QA/QC protocol in processing all rock and soil samples collected

from the core material and soil horizons obtained on the Jackpot property. The protocol included the

insertion and monitoring of appropriate reference materials. High and low concentration certified lithium

standards, blanks and duplicates are used to validate the accuracy and precision of the assay results.

All collected core rock and soil samples were put in sturdy plastic bags, tagged, and sealed in the core

shack under the supervision of a professional geologist. The sample number, depth and brief description

of each sample is logged and entered to a digital database. Rock core samples were split using a

diamond saw with half of the sample remaining in the core box and the other being placed in a labelled

sample bag. Duplicate samples were quarter split and placed into individual sample bags.

All sample bags were put into rice bags and stored securely before being delivered to AGAT

Laboratories in Thunder Bay, Ontario. Samples are processed and crushed at the AGAT facility in

Thunder Bay. Lithium was analyzed by Sodium Peroxide Fusion with ICP-OES and ICP-MS Finish. Soil

samples were placed into small brown paper bags and analyzed by 4-Acid digest with ICP-OES and

ICP-MS Finish.
