Imagine Lithium Inc.: Imagine Lithium Identifies New Lithium Zones on Jackpot Property

Highlights:

• Prospecting has identified six NEW spodumene mineralized zones that are outside the known resource envelope.
• Expansion of the Jackpot lithium mineralization through geological mapping and surface rock sampling.
• Sample results include 4.155% Li2O, 3.918% Li2O and 3.596% Li2O from 145 samples throughout the property.
• The Jackpot Property consists of 297 mineral claims covering 18,800 hectares.

Vancouver, British Columbia--(Newsfile Corp. - October 3, 2025) - IMAGINE LITHIUM INC. (TSXV: ILI) (OTCQB: ARXRF) (the "Company" or "Imagine") is pleased to report a successful field season to expand the known lithium mineralisation on the Jackpot property.

The Jackpot lithium project is located in the Georgia Lake Pegmatite Field, approximately 140 km northeast of Thunder Bay, Ontario (Figure 1). The Jackpot property is characterized by swarms of mineralized lithium-bearing granitic pegmatite dikes distributed over at least five zones on an 18,800 ha land package (Figure 2).

The 2025 exploration program focused on property wide expansion of the known lithium mineralization on the property (Figure 2). Geological mapping and surface rock sampling was completed to follow-up soil geochemical anomalies identified by the 2024 program and additional soil sampling was completed to infill gaps in the older girds. During the 2025 field program, a total of:

• 1,106 field mapping stations were observed;
• 145 surface grab samples were collected for assay outside the current resource envelope;
• 28 muscovite samples were collected for LIBS geochemical analysis;
• 306 soil samples collected from the northern portion of the property (Jackpot West and Newkirk area); and
• 199 soil samples collected from the SW infill grid (north of MNW area).

Results of the geological mapping and sampling program yielded 34 samples that returned greater than 0.10% Li2O, with an additional 8 samples returning tantalum values anomalously higher than 100 ppm Ta in bedrock (Table 1). The highest bedrock sample returned 3.92% Li2O from 85 bedrock samples and the highest boulder sample returned 4.16% Li2O from 60 boulder samples throughout the property (Figure 3).

Of the six new spodumene mineralized zones, Jackpot West and Cosgrave North have in-situ lithium pegmatite on surface (Figure 3). The Jackpot South and Newkirk Zones consist of subcrop and boulders, while the Southwest Zone and Blay Lake Zone are defined by boulders (Figure 3). The Jackpot South, Blay Lake, Jackpot West, Cosgrave North and Newkirk Zones will all be permitted for diamond drilling and bedrock stripping that will be completed in the winter and spring of 2026.

Simone Suen, President of Imagine, commented: "We have discovered lithium mineralization in new areas of the property that have previously been untested and we are currently prioritizing diamond drill targets based on a very productive summer prospecting season. Our team is very excited to commence drilling on these new targets and we are in an excellent position to build on our 3.1 Mt indicated and 5.3 Mt inferred (grading 0.85% and 0.91% Li2O, respectively) Mineral Resource on the project."

Scale (m)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.
