Eureka Conducts Portfolio-Wide Sampling Program and Identifies Large, Outcropping Pegmatites at New Leaf Project, Nunavik, Quebec

Vancouver, British Columbia--(Newsfile Corp. - September 4, 2024) - Eureka Lithium Corp. (CSE: ERKA) (OTCQB: UREKF) (FSE: S580) ("Eureka Lithium" or "Eureka" or the "Company), owner of the largest lithium-focused land package in the top third of Quebec, is actively underway in its 2024 exploration program targeting lithium-bearing pegmatite deposits in the mineral-rich region of Nunavik.

Eureka Lithium is pleased to announce the completion of an aggressive field exploration program at the New Leaf project. This program set out to perform follow-up prospecting, till and lake sediment sampling within areas previously prospected during the Company's 2023 field work. Additionally, reconnaissance prospecting was completed within the newly acquired add-on ground at the Leaf River West and SR Leaf River West properties.

Preliminary Results from New Leaf

The GroundTruth team successfully completed 576 samples in the till program, 404 rock samples, and 153 lake sediment samples.

The new Leaf River West and SR Leaf River West properties contain the largest and most interesting pegmatites observed to date by the field crew. A particularly large, zoned pegmatitic outcrop in the Leaf River West block contains some regions bearing garnet, tourmaline and minor muscovite. This pegmatite is hosted within a metasedimentary package and is hypothesised to be within a fault zone. Pegmatites observed in the SR Leaf River West property contained an abundance of 1-10 cm scale muscovite, tourmaline and garnet. The pegmatites across all Eureka claims are trending NW/SE and are hypothesised to be part of a regional pegmatite swarm. Extensive samples have been collected in both these zones of pegmatites and are pending assay results.

The samples collected during this program are being initially scanned and sorted in the field using a handheld XRF analyzer and all samples will be sent to the laboratories for analysis. A field quality assurance program has been developed which includes retaining traverse trackfiles, inserting QAQC samples for assays, and retaining digital data files of all geological data collected.

DJ Bowen, Eureka interim-CEO commented: "The New Leaf area has shown great prospective geology and we are looking forward to receiving the final results of this 2024 program."
